The present invention inserts a mold mounting base, to which one of the pressing molds is temporarily fixed, to which the other pressing mold is temporarily fixed, in a releasable manner with respect to an opening provided in the mounting panel, and attaches a locking member to the mold. The best mode is to restrict the mold mounting base from falling off when the sheet material is removed by being locked to the base.

The present invention will be described below with reference to the drawings showing embodiments.
The present embodiment corresponds to claims 2 and 9. In FIGS. 1 to 3, a punching die 1 according to the present invention is driven up and down in a sheet material punching device (not shown). A product having a desired developed shape from a sheet material (not shown) supplied to the fixed side surface plate 3 when the slider is driven to move downward toward the fixed side surface plate 3. Die-cut (not shown).

  The mounting board 7 of the punching die 1 is made of a wood board material such as veneer plywood, for example, and a punching blade 9 for punching the product from the sheet material on the lower surface (upper surface shown in FIG. 1) matches the outer shape of the product. Installed. Further, a ruled line blade 11 is attached to the mounting board 7 located in the die cutting blade 9 so as to coincide with the crease portion of the product.

  Further, an opening 7a is formed at an appropriate location in the die cutting blade 9 of the mounting board 7, and a mold mounting base 13 for mounting the pressing die 17 is detachably inserted into the opening 7a. . The mold mounting base 13 is made of, for example, a hard resin material, a wood material, or a metal material, and a lower portion thereof has a stepped locked portion 13a with both sides notched with a required width. A mounting plane portion 13b to which a pressing die 17 (to be described later) is mounted is formed on the lower surface at a height substantially matching the height.

  Each locked portion 13a of the mold mounting base 13 is formed with a shaft hole 13c having an axial line in the vertical direction. A positioning pin 15 as a positioning shaft is inserted into each shaft hole 13c so as to be able to protrude and retract. Each positioning pin 15 is maintained in a state where the shaft upper portion is inserted and fitted into the shaft hole 13c in a state where the lower end of the shaft protrudes slightly below the mounting flat surface portion 13b, and is inserted into the shaft hole 13c. The axial length is set so that the upper end of the shaft does not protrude from the mounting flat portion 13b.

  The above-described positioning pins 15 may be at least two inserted into the shaft holes 13c provided at the asymmetric positions of the respective locked portions 13a, but for example, two at one locked portion 13a, A total of 3 or more is desirable for the other locked portion 13a.

One female pressing die 19 constituting the pressing die 17 is fixed to the lower surface of the mounting flat portion 13b of the die mounting base 13 with, for example, a double-sided tape or an adhesive. The female die 19 is made of, for example, a metal plate such as stainless steel or a resin plate such as PET (polyethylene terephthalate), and has a concave portion (cavity) that matches various symbols such as a company mark, Braille, and an identification symbol to be stamped on its lower surface. 19a) is formed. Further, positioning plates 19b as positioning portions are respectively formed at both ends of the female push die 19 so as to extend in the horizontal direction and be separable at both ends of the mounting flat portion 13b. Each positioning plate 19b has a hole 19c into which the positioning pin 15 is inserted.

It should be noted that the positioning plate 19b in the female push die 19 only needs to be configured so as to be cut off by forming a thin portion 19d or a perforation (not shown) at the boundary portion.

When the female pressing die 19 is fixed to the lower surface of the mounting flat portion 13b, the female pressing die 19 is fixed to the mounting flat portion 13b with the shaft lower portion of the positioning pin 15 inserted into the hole 19c of the positioning plate 19b. The female pressing die 19 is fixed in a state where it is positioned with respect to the flat portion 13b.

Further, a male push die 21 constituting the other of the push die 17 is temporarily fixed to the lower surface of the female push die 19. The male pressing die 21 is made of, for example, a metal plate such as stainless steel, and a protrusion (core) 21a corresponding to various symbols to be pressed is formed on the upper surface thereof. At both ends of the male push die 21 opposite to the positioning plate 19b of the female push die 19, holes 21b through which the lower shafts of the positioning pins 15 through the holes 19c of the female push die 19 are inserted are formed. The holes 19c and 21b are formed by aligning the respective central axes so that the recesses 19a of the female pressing die 19 and the protrusions 21a opposed thereto coincide.

Further, an adhesive material 23 such as a double-sided tape is attached to the lower surface of the male pressing die 21 over almost the whole. A release paper 25 is attached to the pressure-sensitive adhesive surface of the pressure-sensitive adhesive material 23 and is in a non-sticky state.

When the male push die 21 is temporarily fixed with respect to the female push die 19, the positioning pin 15 that is inserted through the hole 19 c and protrudes into the hole 21 b is restricted and temporarily fixed by the frictional force. However, an adhesive such as a double-sided tape or a hot melt (thermoplastic resin adhesive) is interposed between the female pressing die 19 and the male pressing die 21 in a spot shape, so that the adhesive is weaker than the adhesive strength of the adhesive 23. The structure which temporarily fixes with force may be sufficient.

A locking member 27 is attached to the mounting plate 7 corresponding to each corner of the mold mounting base 13 so as to be locked to the locked portion 13a. Each locking member 27 has a locking portion 27a at the distal end portion and a long hole 27b at the base end portion side, and a screw 29 inserted so as to be slidably contacted in a state of being prevented from coming off in the long hole 27b. The mounting board 7 is screwed and moved between a locking position and a non-locking position which will be described later.

That is, each locking member 27 includes a positioning pin 15 in which the locking portion 27a is locked to the locked portion 13a of the mold mounting base 13 and the mold mounting base 13 is inserted into the shaft hole 13c from the mounting board 7. Between the locking position where the positioning pin 15 is prevented from being pulled out and falling off and the locking portion 27a is separated from the locked portion 13a of the die mounting base 13 between the locking position and the non-locking position. It is slidably supported, and is fixed by screwing with a screw 29 at least when moved to the locking position.

Next, the operation and method when attaching the pressing die 17 to the punching die 1 will be described.
First, the positioning pin 15 inserted into the shaft hole 13c of the mold mounting base 13 is moved to a position where the protruding side shaft end slightly protrudes from the mounting flat portion 13b. In this state, the female pressing die 19 is fixed to the mounting plane portion 13b with a double-sided tape or an adhesive in a state where the shaft end of the positioning pin 15 protruding into the hole 19c of each positioning plate 19b is inserted. At this time, the female pressing die 19 is fixed in a state of being positioned with respect to the die mounting base 13 by inserting the positioning pins 15 into the holes 19c. (See Figure 4)

  Next, the male pressing die 21 is fixed to the female pressing die 19 fixed to the mounting flat portion 13b of the die mounting base 13 in the above state, and the shaft ends of the positioning pins 15 inserted into the holes 19c are holes. It is inserted into 21b and overlapped. At this time, the male pressing die 21 is positioned with respect to the female pressing die 19 by inserting the positioning pins 15 into the respective holes 21b, and the protrusions 21a are made to coincide with the recesses 19a. Further, the male push die 21 is temporarily fixed to the female push die 19 by restricting the withdrawal by the frictional force with the positioning pin 15 inserted in the hole 21 b of the male push die 21. (See Figure 5)

  If the friction force of the positioning pin 15 in the hole 21b is weak and the male pressing die 21 can easily come out of the positioning pin 15, a double-sided tape or hot melt is spotted between the female pressing die 19 and the male pressing die 21. Then, the male pressing die 21 may be temporarily fixed to the female pressing die 19 with an adhesive force (adhesive force) weaker than the adhesive force of the adhesive material 23.

  Further, as a mode of attaching the female pressing mold 19 and the male pressing mold 21 to the mold mounting base 13, after the mold mounting base 13 is inserted into the opening 7a of the mounting board 7, the pressing mold 17 is attached to the mold mounting base 13. Either the mounting mode or the mounting mode in which the mold mounting base 13 is inserted into the opening 7a of the mounting board 7 after the pressing mold 17 is mounted on the mold mounting base 13 may be used. .

  Next, prior to the sheet material punching operation, the punching die 1 to which the female pressing die 19 and the male pressing die 21 are attached is fixed to the lower surface of the slider and the release paper 25 is removed from the adhesive 23 on the lower surface of the male pressing die 21. After peeling off, the slider is driven downward to move the cutting edge of the die cutting blade 9 to the lowest point as close as possible to the upper surface of the fixed side platen 3. At this time, the male push die 21 temporarily fixed to the female push die 19 is pressed against the upper surface of the fixed side platen 3 and is fixed by the adhesive force of the adhesive material 23. (See Figure 6)

  Next, when the slider is driven to rise, as shown in FIG. 7, the positioning pin 15 is pulled out from the hole 21 b of the male pressing die 21 fixed to the upper surface of the fixed surface plate 3 and separated. The die 1 is raised with the male push die 21 left. Then, the positioning plate 19b of the female pressing die 19 fixed to the die mounting base 13 of the punching die 1 moved upward is separated by the thin portions 19d positioned at both ends of the mounting flat portion 13b, and each positioning pin 15 is moved to its axis. The shaft hole 13c is immersed so that the lower end substantially coincides with the lower surface of the locked portion 13a. (See Figure 8)

  Next, each locking plate 27 that has been moved to the non-locking position is engaged with the lower surface of the positioning pin 15 in which the locking portion 27a is immersed in the lower surface of the locked portion 13a and the shaft hole 13c. After moving to the stop position, the screw 29 is tightened and fixed. As a result, the slider is driven up and down to restrict the mold mounting base 13 from coming out of the mounting board 7 and the positioning pin 15 from the shaft hole 13c due to the vibration acting when the product is punched from the sheet material. (See Figure 9)

  In this embodiment, the female pressing die 19 is inserted into the positioning pins 15 inserted into the shaft holes 13 c of the die mounting base 13 by inserting the female pressing die 19 and the holes 19 c and 21 b of the male pressing die 21. And the male push die 21 can be attached in a positioned state, and both dies 19 and 21 can be positioned with high accuracy and temporarily fixed.

  In addition, after the male pressing die 21 is fixed to the upper surface of the fixed side surface plate 3, each positioning pin 15 is not necessary. However, by inserting the positioning pin 15 into the shaft hole 13c, it is possible to perform the die cutting operation. It is possible to prevent the positioning pins 15 from being damaged by being pressed against the sheet material, and to form an excessive stamp mark, and the product can be punched out of the sheet material with high quality.

Similarly, after the male push die 21 temporarily fixed to the female push die 19 is fixed to the fixed surface of the fixed-side surface plate 3, the positioning plates 19b provided on both sides of the female push die 19 are used for die cutting work. In some cases, the surface of the sheet material may be damaged and is unnecessary. For this reason, before starting the die cutting operation, the positioning plate 19b is cut and removed to prevent the sheet material from being damaged, and the product can be punched from the sheet material with high quality.

  Further, at the time of the die cutting work of the sheet material, the mold mounting base 13 is moved from the mounting plate 7 by the vibration generated when the slider is lifted and the die cutting blade 9 collides with the sheet material, and the positioning pin 15 from the locked portion 13a. However, the locking member 27 prevents the mold mounting base 13 and the positioning pins 15 from coming out, and the sheet material can be safely punched out.

The present embodiment corresponds to claims 1 and 8 and relates to a punching die 51 that can easily and quickly perform replacement work when changing the stamping die 17 such as a stamped symbol. .
10 and 11, the mold mounting base 13 is detachably inserted into the opening 7 a formed in the mounting plate 7 of the punching mold 51. The mold mounting base 13 has mounting flat portions 13b having locked portions 13a on both sides. The locked portion 13 a is formed so that the upper surface thereof coincides with the lower surface of the mounting plate 7, and the mounting flat portion 13 b has a height that substantially matches the blade height of the die cutting blade 9 provided on the mounting plate 7. It is formed to become.

A female push die 19 that is one of the push dies 17 is fixed to the lower surface of the mounting flat portion 13b in a pre-aligned state. Further, the female pressing die 19 has a male pressing die 21 in which the concave portion 19a of the female pressing die 19 and the protrusion 21a of the male pressing die 21 are aligned, for example, an adhesive such as a double-sided tape provided in a spot shape. Temporarily fixed by an adhesive such as a material or hot melt. The mold mounting base 13 is prepared in advance for each different type of pressing mold 17.

Further, a locking member 27 is provided on the mounting board 7 corresponding to each corner of the opening 7a. Each locking member 27 is supported so that the locking portion 27a can move between a locking position where the locking portion 27a is locked to the locked portion 13a and a locked position separated from the locked portion 13a. When moved to the position, it is fixed by the screw 29.
In addition, about the same member as Example 1, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

In this embodiment, a die mounting base 13 prepared by temporarily holding a female pressing die 19 and a male pressing die 21 in advance according to a symbol of the product to be pressed is inserted into the opening 7 a of the mounting plate 7. After the fitting, the locking portion 27a of the locking member 27 is locked to the locked portion 13a to restrict the die mounting base 13 from coming out of the mounting board 7. (See Figure 12)

For this reason, the present Example can perform the replacement | exchange operation | work of the press die 17 with respect to the mounting board 7 easily and in a short time, and is excellent in workability | operativity. Further, in the mold mounting base 13 attached to the mounting board 7, during the mold drawing operation, the locking member 27 restricts the withdrawal from the mounting board 7, so that the mounting board 7 during the mold cutting work is controlled. There is no risk of disengagement from the mold, and the die cutting operation can be performed safely.

The present invention can be modified as follows.
1. In Example 1, the male pressing die 21 is fixed to the upper surface of the fixed surface plate 3, and then the positioning plate 19b of the female pressing die 19 fixed to the die mounting base 13 is separated. As shown in FIG. 13, an adhesive such as a double-sided tape may be provided in advance on the upper surface of the positioning plate 19b, and the positioning plate 19b may be bent and adhered to the stepped side surface of the mounting flat portion 13b instead of separating the positioning plate 19b. .
Further, instead of bending the positioning plate 19b and adhering and fixing the mounting flat portion 13b to the side surface of the step, the locking member that locks the locked portion 13a after the positioning plate 19b is bent along the step side surface. You may comprise so that 27 may be pressed and a bending state may be maintained.
