The molding apparatus is not limited to the illustrated example, and various other combinations are possible. However, for convenience of description, the illustrated example will be described. In each embodiment, 1 is a partition member, 2 is an outer frame, 3 is a supply means for supplying the granular material M ₁ to the pattern space A inside the partition member, and 4 is an outer frame 2 outside the partition member. Supply means 5 for supplying the powder M ₂ to the pattern space B, an inclination 5 for guiding the flow of the powder M supplied to the pattern space A toward the lower end of the inner surface of the partition member 3, and 6 a pattern space B 3 shows an inclination for guiding the flow of the powder or granules supplied to the partition member 1 toward the lower end of the outer surface of the partition member 1. It should be noted that the powder particles M ₁ and M ₂ supplied to the pattern spaces A and B are dried, water, oil, a lubricant binder,
Water, even if it contains one or more of solvent, curing agent, plasticizer,
Use a dry material that is not kneaded with any of oil, lubricant binder, solvent, hardener, or plasticizer, and can be easily loosened and supplied to the pattern spaces A and B, and then on the reference surface 7. Even after removing the partition member and the outer frame from the reference surface after forming the molded body M, the material does not lose its shape on the reference surface.

The first embodiment of the molding apparatus shown in FIGS. 1 to 8 is for holding a molded body on the reference surface 7 as shown in FIGS. 6 and 7, and the partition member 1 is attached to the outer frame 2. On the other hand, they are concentrically fixed by a connecting rod 11 and slightly project downward from the open lower end of the outer frame. The outer frame 2 has a conical surface whose diameter is reduced downward, and the conical surface has an inclination 6 that guides the flow of the powder or granular material supplied to the pattern space B toward the lower end of the outer surface of the partition member 1. .

The powder and granular material supplying means 3 and 4 are composed of an inner cylinder 13 and an outer cylinder 14 of a supply tank 12 which is composed of concentric inner and outer double cylinders. The supply tank 12 is a bottom plate 15 that closes the lower ends of the inner cylinder and the outer cylinder.
And a circular shutter 18 that rotates on the bottom surface of the bottom plate.

As shown in FIG. 2, the bottom plate 15 has concentric arc-shaped holes 1 inside and outside, which can communicate with the inner cylinder and the outer cylinder, respectively.
Two 6 and 17 are provided. The arcuate holes 16 and 17 are each slightly shorter than the semicircular arc. 2 between arcuate holes 16 and 16
One of the two spacings 16a and one of the two spacings 17a between the arcuate holes 17 and 17 are located in the same radial direction, and the other spacing 16b between the arcuate holes 16 and 16 and the spacing between the arcuate holes 17 and 17 are On the other hand, 17b is different in radial position.
Further, the shutter 18 is provided with a fan-shaped outlet 19 communicating with the arc-shaped portions 16 and 16 and a fan-shaped outlet 20 communicating with the arc-shaped holes 17 and 17 concentrically at the same radial position. As a result, the discharge ports 19 and 20 are separated from each other by the space 16 between the arcuate holes 16.
The discharge ports 19 and 20 are closed by arranging them below the space 17a between the a and the arcuate hole 17 (see FIG. 7).
In addition, the discharge port 19 has a space 16b between the arc-shaped holes 16 and the other side of the arc-shaped holes 16.
When positioned below, the outlet 20 communicates with the arcuate hole 17, and conversely the outlet 20 is spaced apart from the arcuate holes 17 and 17 by the distance 1
When located below 7b, the outlet 19 communicates with the arcuate hole 16.

On the supply tank 12, a motor 21 with a rotating shaft 22 facing downward is supported by several stays 23. The rotating shaft 22 passes through the center of the inner cylinder 13, and the lower end of the rotating shaft 22 is the bottom plate 15.
And the center of the shutter 18 is fixed. Therefore, the shutter 18 is rotated by the motor 21, and when the discharge port 19 communicates with the arcuate hole 16, the powder or granular material M ₁ in the inner cylinder 13 which is the supply means 3 flows down from the discharge port 19. Similarly, when the discharge port 20 communicates with the arcuate hole 17, the granular material M ₂ in the outer cylinder 14 which is the supply means 4 flows down from the discharge port 20. When the rotation of the shutter 18 is stopped and the gap 16b between the arcuate holes 16 and 16 closes the discharge port 19 at that time, the powder M ₂ flows down from the discharge port 20 and the gap 17b between the arcuate holes 17 and 17 is reduced. When the discharge port 20 is closed, the granular material M ₁ flows down from the discharge port 19. When the motor 21 stops rotating, the space between the arcuate holes 16
a, 17a is at a position where the discharge ports 19 and 20 are closed at the same time, and a space 16b is at a position where the discharge port 19 is closed.
A controllable stop position is used so that the discharge port 7 can be closed by 7b.

The outer frame 2 in which the partition member 1 is concentrically fixed is replaceably attached by an appropriate means. When the outer frame 2 is thus attached below the supply tank 12, the lower end of the inner cylinder 13 of the supply means 3 is located on the pattern space A surrounded by the partition member 1, and the lower end of the outer cylinder 14 of the supply means 4 is the partition member. It is located on the pattern space B surrounded by the outer frame 2. The partition member 1 fixed concentrically to the outer frame 2 has a continuous star shape in the case of FIG. 3, a continuous moon shape in the case of FIG. 4, and a discontinuous sun shape in the case of FIG. Since the outer frame to which these partition members are fixed is provided with a brim that is joined to the brim of the bottom plate 15, it can be replaced and attached below the supply tank 12.

[0011] have manually supply tank 12, against the lower end of the partition member 1 in the reference plane 7, when driving the motor 21, granular material M ₁ from supply means 3 by the rotation of the shutter 18 is the partition member 1 is enclosed The powder M ₂ from the supply means 4 flows down into the pattern space A, and flows down into the pattern space B surrounded by the outer frame outside the partition member (FIG. 6). Since the outer frame 2 has the slope 6, the powder M _{2 that} has flown down into the pattern space B is pressed to the outside of the partition member 1 by the slope 6. Therefore, as shown in FIGS. 7 and 8, when the outer frame and the partition member are pulled up from the reference surface together with the supply tank, the molded body M in which the powder particles M ₁ and M ₂ are integrated is formed on the reference surface. Molded. Further, when the amount of the powder or granular material M ₁ forming the compact is insufficient, the shutter 18
To close the discharge port 20 with the space 17b between the arcuate holes 17,
Powder M ₁ is added from the discharge port 19. Similarly, powder M
_When the amount of ₂ is insufficient, the discharge port 19 is closed at the interval 16b between the arcuate holes 16 and the powder M ₂ is added from the discharge port 20. The molded body M is hardened by humidifying it if necessary. Alternatively, the reference surface 7 may serve as a backing layer, and the reference surface 7 may be molded on the backing layer to be solidified together with the backing layer. Although the opening at the lower end of the outer frame 2 has a similar shape which is slightly larger than the partition member 1 in the illustrated embodiment, the opening is not limited to this and may be circular, polygonal or the like.

In the second embodiment of the molding apparatus shown in FIGS. 9 to 11, the partition member 1 and the outer frame 2 are separated, the partition member is arranged on the reference surface 7, and the outer frame and the supply means 3 and 4 are connected to the hand robot 30. Then, the outer frame is put on the partition member from above to form a molded body.
Also in this embodiment, the powder and granular material supply means 3 and 4 are constituted by the inner cylinder 33 and the outer cylinder 34 of the supply tank 32 which is composed of concentric inner and outer double cylinders. The outer frame 2 is replaceably attached to the lower end of the outer cylinder 34 with bolts, nuts and the like. The outer cylinder 34 includes a closing lid 35 that closes the upper end, the inner cylinder 33 is concentrically supported through the closing lid 35, and the lower end thereof is located inside an outer frame attached below the outer cylinder. 36 is a storage tank for the powder particles M ₁ supplied to the pattern space A surrounded by the partition member 1, 37 is a storage tank for the powder particles M ₂ supplied to the pattern space B surrounded by the outer frame of the partition member, The powder M ₁ is supplied to the inner cylinder by a flexible pipe conveyor 38 with a built-in screw connected to the upper end of the inner cylinder 33 protruding above the block 35, and the powder M ₂ in the storage tank 37 is connected to the lid 35. It is supplied to the outer cylinder by a flexible pipe conveyor 39 with a built-in screw.

To form the molded body, the partition member 1 is placed on the reference surface. In this arrangement, a magnetic head 40 having a large number of electromagnets arranged in a matrix is attached to the arm robot 31, and a predetermined partition member placed in a storage place is attracted by the magnetic force of the magnetic head 40 and placed on a reference plane. The magnetic head is demagnetized, and the magnetic head is retracted from the partition member.
The partition member 1 is made of a magnetic material such as a thin iron plate. When the partition member 1 is placed on the reference plane in this way, the hand robot 30
Is operated to surround the partition member 1 with the lower end opening of the outer frame 2 fixed to the lower end of the outer cylinder, position the lower end of the inner cylinder 33 on the partition member 1, drive the pipe conveyors 38, 39, and store the storage tank 36.
The dry powdery particles M ₁ and M ₂ in 37 and 37 are supplied to the pattern space A surrounded by the partition member 1 and the pattern space B surrounded by the outer frame outside the partition member via the inner cylinder and the outer cylinder. The start and stop of the supply of the powders M ₁ and M ₂ and the supply amount are adjusted by the start and stop of the pipe conveyor, the driving time, and the like. Since the outer frame 2 has the slope 6, the granular material M _{2 that} has flown down into the pattern space B is pressed to the outside of the partition member 1 by the slope. When the supply of the powder and granules is completed in this way, the outer frame is pulled up together with the supply tank by the hand robot, and then the arm robot 31 described above is operated,
The magnetic head 40 is positioned directly above the molded body, the electromagnet is excited, the partition member 1 is pulled right above and adsorbed, and the partition member is removed from the molded body. The traces from which the partition member is removed are filled with the powder particles M ₁ and M ₂ by collapsing, and thus the molded body M is molded on the reference surface 7. The molded body M is hardened by humidifying it if necessary. Also, the reference surface 7 is used as a backing layer,
You may shape | mold on it and may harden it integrally with a backing layer.

The powder and granule storage tanks 36 and 37 are, for example, a plurality of tanks containing powder and granules of different colors. A shutter is provided at the outlet of each tank to open and close it, and it is connected to pipe conveyors 38 and 39. However, the shutters may be operated to select the powder particles M ₁ and M ₂ of arbitrary different colors and supply them to the pattern spaces A and B.

In any of the embodiments shown in FIGS. 1 to 8 and 9 to 11, as shown in FIGS. 12 and 13, the powder or granular material M ₁ flowing down from above is placed above the inside of the partition member 1, that is, the partition member. If a small diffusing plate 8 having a similar shape and having a slope 5 that diffuses toward the lower end of the inner surface of is attached concentrically with a stay or the like, the density of the powder M ₁ in the outer peripheral portion of the pattern space A is increased, The boundary with the granular material M ₂ supplied to the pattern space B can be expressed sharply.

In the embodiment shown in FIGS. 14 to 17, a plurality of (three in the figure) partition members 1 are provided inside a rectangular outer frame 2.
Is attached by slightly projecting downward from the open lower end of the outer frame. The outer frame is a pyramid whose outer shape is reduced downward, and the conical surface has an inclination 6 that guides the flow of the powder M ₂ supplied to the pattern space B toward the lower end of the outer surface of each partition member 1. ing. The outer frame is attached to the lower end of an outer hopper 51 of the same shape as the feeding means 4. Inside the outer hopper, an inner hopper 52 as a supply means 3 is fixed by a stay 53 apart from the inner surface of the hopper. A plurality of holes 54 having the same shape as the partition member are opened at the bottom of the inner hopper at intervals, and the partition member 1 is vertically provided below the hole. A shutter 55 can be inserted from the outside of the outer hopper onto the bottom surface of the inner hopper to close the hole 54.
Further, two shutters 56 can be inserted from the outside of the outer hopper to close the space between the outer hopper and the inner hopper. The shutter 56 is an L-shaped plate, one of which is inserted from the left, and the other of which is reversed in direction and inserted from the right. Supply tank 50 including the outer hopper 51 and the inner hopper 52
Is movable across the reference plane 7 in the width direction (Y direction) of the reference plane and in the vertical direction on the portal frame 58 which is movable by being guided by the rail 57 in the longitudinal direction (X direction) of the plane. It is attached to. For example, on a gate-shaped frame, a carriage that is guided by the frame and is movable in the width direction of the reference plane is provided,
The supply tank 50 may be provided so as to be vertically movable with respect to this dolly.

[0017] To do molding placed granular material M ₁ in the inner hopper 52, add powder or granular material M ₂ in the interior surrounding the outer hopper 51 outside of the inner hopper. For that purpose, the powder M ₁
Then, the storage tanks 59 and 60 containing M ₂ and M ₂ are arranged above the end portion outside the reference plane in the X direction, and the supply tank 50 is moved directly below the storage tank 59 to receive the supply of the granular material. . And
The gate-shaped frame 58 and the supply tank 50 are moved on the reference surface 7 and stopped at a predetermined position, the supply tank is lowered to bring the lower end of the partition member 1 into contact with the reference surface, and the shutters 55 and 56 are opened.
The granular material M ₁ in the inner hopper 52 is caused to flow down into the pattern space A in the partition member, and the granular material M ₂ in the outer hopper 51 is caused to flow down into the pattern space B surrounded by the outer frame of the partition member. Since the outer frame has the slope 6, the granular material M ₂ that has flowed down into the pattern space B
Is pushed to the outside of the partition member 1 by the inclination. Powder M
_{When 1} and M ₂ flow down by a predetermined amount, the shutters 55 and 56 are closed and the supply tank 50 is raised. Thereby, the molded body M having, for example, three star patterns is molded on the reference surface.
The molded body M is hardened by humidifying it if necessary.
Alternatively, the reference surface may be a backing layer, and the backing layer may be molded on the backing layer to be solidified together with the backing layer.

As described above, not only the examples shown in FIGS. 1 to 17 but also various shapes, materials and combinations thereof can be used, and the partition member and the outer frame are not limited to the star shape, the moon shape and the sun shape. Various shapes can be used according to the pattern to be expressed. The partition member may be continuous or discontinuous, and the discontinuous member may have various shapes such as a pin, a small piece, a corrugated small piece, and a spiral. Further, the partition member may be one that simultaneously expresses a plurality of patterns as shown in FIG. 14 or one that expresses multiple patterns. Further, the height of the partition member may be determined in consideration of the finished thickness of the pattern. Furthermore, whether the lower end of the partition member is in close contact with the reference surface
It may be selected according to the pattern to be expressed. Materials for the partition member and outer frame include metals, ceramics, plastics,
Materials made of rubber, paper, wood, woven cloth, non-woven cloth, etc. can be used, and it is clearly defined that the reference surface and the partition member should be a combination of materials that can adhere to each other. Desirable for expression. In any of the devices, a peripheral frame may be further provided outside the supply port for supplying the granular material to the pattern space outside the partition member, if necessary.
By vibrating the outer frame and the supply tank at the time of supply, it is possible to supply evenly, and when removing the partition member from the granular material layer,
It can be removed cleanly by vibrating the outer frame and supply tank. Further, a vibration device may be attached to other portions as necessary. If a non-woven fabric, knitted fabric, paper, etc. that is breathable or liquid-permeable is used as the reference surface, it will adhere and at the same time prevent the powder particles from slipping, and also secure the strength and uniformity of the molded product. desirable. As the reference surface, any material such as a form bottom plate, a sheet, a belt, and a plate can be arranged as long as the device can be arranged, and a double-acting press bottom plate may be used as the reference surface, or a conveyor as the reference surface. It is also possible to use the bottom plate of the mold placed on the top, and further, an endless one such as a belt conveyor may be used as the reference surface. Alternatively, the powder / granular material layer may be placed as it is or inverted, and the powder / granular material layer may be placed on the board or sheet as a reference surface. For the opening and closing mechanism such as shutter and valve, manual, electric, pneumatic, hydraulic etc. type can be used.
It may be determined in consideration of the function, and the attaching / detaching mechanism of the outer frame with respect to the supply tank may be of a magnetic type, an adhesive type, a tightening type, a screw type, a fitting type, a hook type, or the like. Further, when arranging one or a plurality of frame bodies on the reference plane, the arrangement and removal of the frame bodies are not limited to the magnetic method shown in FIG. 2, and any other method may be used. A vibrating device, a static eliminator, various auxiliary tools, and the like may be attached to any of the devices, if necessary. By changing the height and shape of the frame and controlling the supply amount, the thickness to be supplied can be changed arbitrarily, or by changing the partition member, it moves from a continuous clean line to a mixed line In addition, various complex and sophisticated expressions can be realized by controlling the supply and using a combination of continuous color mixing devices. The whole device can be combined with various positioning devices such as the articulated robot of FIG. 9, and various methods such as XY table, combination of gate frame and conveyor, combination of horizontal robot and conveyor are taken. You can
Further, as shown in FIG. 14, a multi-feed port type device having a plurality of feed ports may be used. In addition, it is easy to install because it has a simple mechanism, and since it is possible to use a tube, it does not take up space,
It can be attached to existing equipment that requires speed and space, and can be used as a device for manufacturing various molded products, which does not cost much and allows quick start-up to production.

When the molding apparatus of claim 1 is used and the molding of FIG. 18 is molded by the method of claim 2, the apparatus of FIG. 1 is held by hand and is partitioned on the bottom plate of the frame 71 serving as a reference plane. Abutting the member, the yellow material 7 is placed in the pattern space A inside the partition member.
2. When the white material 73 is supplied to the pattern space 13 outside the partition member and the device is removed, a molded body M having a yellow star-shaped pattern in a white background on the reference surface is formed by the powder particles. This is repeated, for example, 9 times, and then the white material 73 'is supplied to the remaining reference surface in the frame by hand or another method. For example, when the apparatus shown in FIG. 1 is used as it is for supply, the supply port 16 for supplying the yellow material is closed and the supply port 1
Only the white material from 7 is supplied to the remaining space in the frame, and after that, the backing layers are overlaid as necessary, and then the respective materials are solidified together. The traces of the partitioning member are filled up cleanly as each material collapses. Also, in the case of FIG. 14, the gate frame is moved,
The molded body having the three star patterns is repeated three times and molded in the frame. On the other hand, in the case of the apparatus shown in FIG. 9, if nine partition members are arranged in advance on the reference plane and yellow material is supplied to the pattern space inside the partition member and white material is supplied to the pattern space outside the partition member, respectively. Good.

As another example, in order to mold the molded body of FIG. 20, the apparatus of FIG. 1 is used. For example, first of all, an outer frame having a star-shaped partition member is attached to a supply tank and a reference surface is attached. A partition member is brought into contact with the bottom plate of the frame 71, and a dry yellow material 72 is supplied to the pattern space A, and a dry white material 73 is supplied to the pattern space B. Then, the device is removed from the reference surface. Make a molded body 74 with a yellow star in the white background on the reference surface, then replace the outer frame with one having a moon-shaped partition member, operate in the same manner, and place it in the white background on the reference surface. Create a yellow moon-shaped feature 75, replace both the dry powder and granules in the supply tank and the outer frame to form a red sun-containing compact 76, and white material on the rest of the reference plane in the frame. 73 'is supplied by hand or other method, and after stacking a backing layer as needed, the respective materials are solidified. The traces of the partition member 1 are filled up cleanly as each material collapses. In the case of the apparatus of FIG. 9, star-shaped, moon-shaped, and sun-shaped partition members are arranged in advance on the reference plane, and the pattern space inside the partition member 1 and the pattern space outside the partition member 1 are arranged. Each material may be supplied, the partition member may be removed by the magnetic head 40, and the pattern layer may be formed. In this case, since the sun-shaped partition member 1 is a discontinuous partition member, by supplying the red material first, the red material protrudes outside the discontinuous portion, and the flare of the sun can be expressed. Since the star-shaped and moon-shaped partition members are continuous partition members, either material may be supplied first.

In any case, which molding apparatus is used and how the pattern is expressed is arbitrary, and various patterns are not limited to the above examples depending on the combination of various devices and various expression methods. The expression and molded body of Furthermore,
Even when a molded product having the same pattern is molded, it is arbitrary which partition member or outer frame is used and how it is expressed, and various other methods can be adopted. In any case, a pattern can be beautifully expressed by controlling the supply amount at the time of supplying the material. In addition, when the material of the reference surface is made of rubber, sponge, paper, non-woven fabric, etc. and has some bulkiness or elasticity, when the partition member of the frame is pressed, the reference surface and the partition member are separated from each other. In between, it becomes possible to take a play, positioning of the frame body in the height direction becomes easy, and moreover, since it is more firmly separated by the partition member, a sharp line can be drawn. Similarly, an elastic body such as a spring or rubber may be used for a part or all of the frame body to press the frame body, or an elastic material such as a string or a string may be attached to the contact surface of the partition member. In any case, it is desirable to use a continuous color blending device and add pigments, colorants, etc. as coloring materials to the base material before supply, so that a full-color expression can be achieved. Therefore, when the work is advanced to a dark color, it is desirable that the influence of the mixing of the coloring material is small. In any case, by applying vibration to the frame and the supply port,
It is preferable that it can be evenly supplied at the time of supply, and further, when the frame body is removed, it collapses and can be molded densely. In any case, the press plate under the double-acting press may be used as a form bottom plate as a reference surface, and after the pattern is expressed on the press plate, the parts may be integrally pressure-molded. Further, after a large number of pieces are integrally molded and hardened, they may be cut into individual pieces.

The dry pattern material for producing a molded product by the method of the present invention contains water, oil, even if it contains at least one of water, oil, a lubricating binder, a solvent, a curing agent and a plasticizer. Use a dry one that is not kneaded with any of a lubricant binder, solvent, hardener, or plasticizer, and that can be easily loosened and supplied onto the reference surface. Even when using a dry backing material, wet water, oil, lubricating binder, solvent, hardener,
A mixture of one or more plasticizers may be used, or other materials such as metal, wood, cement, glass, boards such as ceramics, paper, non-woven fabric, woven fabric, plastic Sheets such as a sheet can be used. When boards or sheets are used as the backing material, the boards or sheets serve as the reference surface. Further, the pattern material may be layered and integrated with various existing moldings as a reference surface. As the above-mentioned various materials for producing the molded body, different finishes such as different materials or colors, gloss, and texture are used depending on the molded body to be manufactured.

The dry patterning material for producing a concrete molded body is cement powder or resin simple substance,
Alternatively, the main component is a mixture thereof, and further, a mixture obtained by adding a pigment or fine aggregate to them. Further, the backing material is mainly composed of cement powder or resin alone, or a mixture thereof, or a mixture of fine aggregate added to them, and if necessary, a pigment, coarse aggregate or various fibers. A mixture containing one or both of them, which may be dry like the pattern material, or may be wet such as fresh concrete kneaded with water or the like.
In addition, if necessary, wood chips can be used as aggregates or fine aggregates for both patterning materials and lining materials, and crushed stones and powders of granite and marble, slag, light-reflecting particles, and inorganic hollows such as shirasu balloons Crushing or crushing powder of the body, ceramics, granules and powders of new ceramics, powders or grains of metal or other minerals, mixing of setting hardening accelerator, waterproofing agent, expanding agent and other admixtures Sometimes. The above-mentioned various fibers include metal fibers, carbon fibers, synthetic fibers, glass fibers and the like. Then, in order to solidify the respective materials together, a necessary amount of water or the like is added as it is, but when a wet backing material is used together, the amount of water added is reduced in consideration of water exuding from the backing material. Further, other backing materials, for example, boards such as metal, wood, cement, glass, and ceramics, or sheets such as paper, non-woven fabric, and woven cloth may be solidified together. It is also possible to make patterned asphalt concrete or the like using a heat-melting material such as asphalt.

The patterning material and the lining material for producing the artificial stone compact are one or two kinds of granules such as rock grains, ceramic grains, new ceramic grains, glass grains, plastic grains, wood chips, and metal grains. A mixture of aggregates containing a pigment if necessary, and a curing agent added to bond the mixture aggregates, wherein the curing agent is cement powder and water, cement powder and resin and water, or resin and water. Or solvent, or a mixture of these with a powder consisting of one or more of rock, ceramics, new ceramics, glass, and plastics as a main component, and if necessary, a mixture containing a pigment and a coloring agent. Powder or granules, various fibers, various admixtures and various additives may be mixed. Incidentally, the various powders or grains, slag and fly ash, light-reflecting grains and other substances, each fiber, metal fibers, carbon fibers, synthetic fibers, glass fibers, etc., various admixtures and various additives Are shrinkage inhibitors, setting hardening accelerators, retarders, waterproofing agents, swelling agents, water reducing agents, fluidizing agents and the like. Also, for the mixed aggregate,
In order to improve the adhesion to the curing agent, water, a solvent, a surface treatment agent, etc. may be sprinkled or dipped in these if necessary. Then, in order to solidify the material integrally, a curing agent may be spread between the aggregates by vacuum suction or the like, and as the lining material, a mixture of the aggregate and the curing agent may be used in advance.

The material used in the present invention is not limited to the exemplified ones, but different materials or materials having different finishes such as colors and textures can be used in combination depending on the molded product. Sand or metal powder can be used to mold molds and form sintered metal with patterns.

In any of the moldings, when the powder is supplied to the reference surface, vibration is applied to smooth the movement of the powder and granules. Further, the boundary of the pattern material can be disturbed by a brush, a comb, an air jet, a water jet, etc. to blur the pattern.

Further, at the time of molding, by laying a non-woven fabric or other water-absorbing or oil-absorbing mat on the reference surface or the pattern layer, excess water, oil, lubricating binder, plasticizer, solvent in the material is removed. Absorbed by the mat or excess water of some of the material,
The oil, the lubricating binder, the plasticizer and the solvent can be replenished to other parts where it is deficient, and the water, the oil, the lubricating binder, the plasticizer and the solvent in the entire molding are made uniform. Further, as a result, the surface water (auxiliary agent): cement (resin) ratio becomes smaller, and the strength of the molded product can be improved. Further, when the air-permeable mat is used for pressure molding, deaeration is assisted and a dense molded body can be formed. Further, when solidifying, one or both of the pattern layer and the backing layer may be vibrated or pressed so that the pattern layer becomes solid and the strength can be improved. Furthermore,
Various long fibers and short fibers can be put between the pattern layer and the backing layer or in the layer to reinforce by inserting wire mesh or rebar.The backing layer can be formed by a papermaking method or an extrusion molding method. By using various boards and sheets, it is possible to deal with molded articles for various purposes such as construction panels and boards, wall sheets, and tiles. Alternatively, the reference surface may be an existing concrete molding, for example, and a pattern layer may be laid on it to be solidified integrally with the existing molding.

As described above, according to the present invention, even in the case of a complicated pattern such as a star shape, the powder can be efficiently supplied to the inside and outside of the partition member by holding it with a simple device. And, in order to express the repeating pattern thickly, when an auxiliary frame or the like is used,
I used a combination of multiple auxiliary frames and partition members, and I needed a mask to fill the auxiliary frames.
According to the present invention, without using a large-scale device or a mask,
It becomes possible to express with a simple device, and since it is not necessary to connect a plurality of auxiliary frames and partition members, it is possible to freely express a variety of perfect repeating patterns, and by exchanging the frame body, Various shapes can be expressed, and it has become possible to handle both small-area molded products and large-area molded products. As a result, it has become possible to reduce the cost required for production. By these manufacturing methods, the pattern layer is exposed on a part or the whole surface to express the pattern, a concrete molded body, an artificial stone molded body, a ceramic molding sintered body or a ceramic molded body, a thick coating molded body, Plastic molded products, confectionery and other molded foods can be easily manufactured, and even if the surface of the pattern layer is worn away, the expressed pattern disappears,
It doesn't get ugly. And since the pattern layer is formed by a combination of dry pattern materials, each material collapses and can be supplied without gaps, the boundaries between pattern layers can be expressed in detail, and the pattern is very clear. Further, after supplying each pattern material, the boundary part of the pattern or the entire pattern is disturbed, so that a unique pattern having a texture of marble or other various natural stones can be expressed. In the case of a sintered body of a ceramic molded body or a ceramic molded body, two or more kinds of materials having different properties such as an insulator, a conductor, a semiconductor, a dielectric, a piezoelectric body, and a magnetic body are combined and cured integrally. Thus, various large-capacity elements, circuits, antennas, etc. can be easily manufactured. Furthermore, even if the boards for construction are chamfered, the same pattern will appear, and the cutting process can be freely performed.
