  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  This embodiment is a positioning device used when exchanging molds of an injection molding machine.

  In the drawings, reference numeral 1 denotes a base disposed in an injection molding machine. An upper end surface (hereinafter referred to as “base surface”) 1 f of the base 1 constitutes a horizontal contact surface (reference surface) on which a mold M as a workpiece is seated. A platen 2 stands up from the base 1, and a side surface (hereinafter referred to as “platen side surface”) 2f of the platen 2 is configured as a plane substantially perpendicular to the base surface 1f.

The mold M is a board-like member having a flat lower end surface F ₁ that can be seated on the base surface 1 f, and a back surface (side surface) F ₂ formed so as to be orthogonal to the lower end surface F _1. .

On the other hand, a paralleling member 3 with which the back surface F _{2 of the} mold M contacts is provided on the platen side surface 2f. Each of the paralleling members 3 is set so that the front end surface 3f has an equal length L ₀ (see FIG. 4) from the platen side surface 2f. Thus, the mold M, when contacting the back F ₂ on the distal end surface 3f, as shown in FIG. 3, away from the platen side 2f distance L _0, the position near the platen side 2f, platen side Aligned parallel to 2f.

A lateral groove extending in the width direction is formed on the platen side surface 2 f so as to be cut out from the side surface of the platen 2. From the notch portion of the horizontal groove, the paralleling member 3 is detachably fitted into the horizontal groove. Thereby, the paralleling member 3 can be attached or detached from the platen side surface 2f as needed. That is, unlike the platen side 2f of the present embodiment, when the irregular surface of different widths to the back F ₂ of the mold M is formed, parallel out as place the distal end surface 3f abuts avoid uneven The member 3 is disposed. Note that the paralleling member 3 can be used not only when the concave and convex shapes and the curved shape are present on the back surface F _{2 of the} mold M, but also when the back surface F ₂ is a surface parallel to the platen side surface ₂ f. it can.

Reference numeral 4 denotes crane means for suspending the mold M so that the lower end face F _{1 of the} mold M is on the lower side.

  The crane means 4 has an arm 4a that can be swung and expanded and contracted, and a deformable linear member 4b typified by a wire or a chain hangs down from the distal end side of the arm 4a. The linear member 4b can be detachably fixed to the upper end side of the mold M by a locking means such as a hook. Thereby, as shown in FIG. 1, the crane means 4 can suspend and hold | maintain the metal mold | die M so that raising / lowering is possible by drawing out and winding up the linear member 4b via the arm 4a.

  Reference numeral 10 denotes a positioning tool for positioning the mold M with respect to the platen 2.

As shown in FIG. 2, the positioning tool 10 stands up from a cylindrical roller member 11, a main body 12 on which a road surface F _{r serving as} a rolling surface of the roller member 11 is formed, and a side surface of the main body 12. And two side walls 13 extending along the road surface F _r .

Each of the side walls 13, along the road F _r slit (long hole) 13s are formed. Each of the slits 13s passes through a shaft portion 11a protruding from the side surface of the roller member 11. Thus, when the roller member 11 is assembled together with the main body 12 and the side wall 13, the roller member 11 is held by the main body 12 and the side wall 13 so as to roll along the road surface F _r .

Further, in this embodiment, by raised one end of the road F _r formed in the body 12, and constitutes the end as bulging portion 12a. A magnet 14 is incorporated in the bulging portion 12a so that a magnetic field is formed on the road surface _Fr side. Thus, if the roller member 11 is made of a magnetic material such as alloy tool steel (for example, SKS3), the initial position of the roller member 11 is a position adjacent to the bulging portion 12a as shown in FIG. Can be easily set.

In addition, the bulging part 12a can be made to function also as a stopper surface which controls the rolling of the roller member 11 with the longitudinal direction edge part of the slit 13s. Also, the magnet 14 is, for example, as shown in FIG. 2 (a), the inside of the raised portion 12a, to form a penetrating hole 12n which form the openings A ₁ on the side surface f ₁₂ of the raised portion 12a, the introducing hole 12n It fixes with the fixing member 16 in the state fitted inside. Thereby, the magnet 14 is held in the main body 12 so as not to be detached.

  Further, in this embodiment, the main body 12 is provided with a handle 15 for operating the tool 10. By providing the handle 15, the operability as the tool 10 is improved. Thereby, the tool 10 can be positioned at a desired position on the base surface 1f in a simpler and shorter time.

Next, a method for seating the lower end surface F ₁ of the mold M on the base surface ₁ f using the positioning tool 10 so that the back surface F _{2 of the} mold M is parallel to the platen side surface ₂ f will be described.

If lifting the mold M using the crane unit 4, that the center of gravity O _M of the mold M is moved, as shown in FIG. 1, as the lower end surface F ₁ of the mold M is moved away from the platen side 2f When tilting, first, as a first step, the positioning tool 10 is taken out, and the roller member 11 of the tool 10 is raised as shown in FIG. 2 so that the raised portion 12a side is the initial position. Positioning is performed by moving toward the portion 12a. Thereby, the roller member 11 is positioned so as not to roll easily by the magnet 14.

Next, as a second step, the positioning tool 10 is arranged on the base surface 1 f using the handle 15. Upon placing the positioning tool 10, the position of the rolling axial O _r of the roller member 11, as shown in FIG. 3, be between the base surface 11 and the mold M, from the platen side 2f by a dimension L ₁ It is positioned so that it is located directly below the center of gravity O _M when the mold M is hung, or just below the position L ₂ closer to the platen 2 than the center of gravity O _M. That is, the positioning tool 10 is positioned on the base surface 1 f so that the lower end surface F _{1 of the} mold M is placed on the roller member 11 as the mold M is lowered.

After the positioning tool 10 is arranged, as a third step, the mold M is lowered toward the base surface 1f using the crane means 4 as shown in FIG. When lower the mold M, among the parallel producing member 3 provided on the platen 2, with the back F ₂ of the upper edge 3p mold M parallel producing member 3 in the upper contacts, the mold M The lower end surface F ₁ contacts the roller member 11. Then, the upper edge 3p of the paralleling member 3 becomes a fulcrum, and a part of the weight of the mold M is given to the roller member 11 as a horizontal component force. Thereby, the roller member 11 in the positioning tool 10 rolls toward the platen 2 along the road surface F _r formed on the main body 12, and the mold M placed on the roller member 11 is also a roller member. As shown in FIG. 4, the lower end surface F ₁ of the mold M becomes horizontal as a result of the movement toward the platen 2 with the rolling of the mold 11, and as a result, the mold M stands up.

As the mold M stands up, the back surface F _{2 of the} mold M comes into contact with each of the front end surfaces 3 f of the paralleling member 3, so that the mold M is arranged in parallel to the platen side surface 2 f. . A support member (parallel member) 5 for placing the mold M is disposed on the base surface 1f. The upper end surface 5 f of the support member 5 is configured as a flat surface such that the back surface F _{2 of the} mold M is parallel to the platen 2 when the lower end surface F ₁ of the mold M is seated. Therefore, the positioning tool 10, as shown in FIG. 4, as the lower end surface F ₁ of the mold M is seated on the upper end face 5f of the support member 5 is positioned with respect to the base surface 1f.

After the mold M is arranged in parallel to the platen 2, as shown in FIG. 5, the pressing member 6 is installed on the base surface 1f as a fourth step. The pressing member 6 has a side surface 6 f that presses the front surface F _{3 of the} mold M and presses the mold M against the front end surface ₃ f of the paralleling member 3. The pressing member 6 can be detachable from the base surface 1f, for example. In this embodiment, the support member 5 is placed on the base surface 1f in advance. However, the support member 5 can be disposed together with the pressing member 6 in the fourth step. That is, in the third step, the support member 5 is not necessarily required.

  Following this, as shown in FIG. 6, the mold M is slightly lifted using the crane means 4 as shown in FIG. 6, and then the handle 15 is used as the sixth process as shown in FIG. 7. Then, the positioning tool 10 disposed between the mold M and the base 1 is removed.

After removing the positioning tool 10, as a seventh step, the lower end surface F ₁ of the mold M is seated on the upper end surface 5 f of the support member 5 by lowering the mold M again using the crane means 4. . Thus, the mold M is installed in the injection molding machine so as to be parallel to the platen 2. In this embodiment, the leveling member 3 and the support member 5 are left as they are on the platen 2, but can be removed from the platen 2 as necessary.

By the way, according to the present invention, it is between the base surface 1f and the mold M, and is directly below the center of gravity O _M when the mold M is suspended, or closer to the platen 2 side than just below the center of gravity O _M. a position, when placing the rolling axial O _r of the roller member 11, as described above, simply by interposing the positioning tool 10 with a roller member 11 between the base surface 1f and the mold M In addition, the roller member 11 can be directly provided on the mold M.

Further, according to the present invention, as long as the relationship between the position of the rolling axial O _r position the roller member 11 of the center of gravity O _M hanging obtained mold M is satisfied, the other embodiment shown in FIG. 9 Thus, the mold M can be arranged in parallel to the platen 2 simply by placing the roller member 11 on the base surface 1 f. In this embodiment, the roller member 11 is placed via the pedestal member 7 disposed on the base surface 1f, but the presence or absence of the pedestal member 6 is arbitrary. Further, the upper end surface 7f of the base member 7 on which the roller member 11 is placed is configured by a plane parallel to the base surface 1f. Even with such a simple configuration, the positioning method according to the present invention can be realized.

As described above, according to the present invention, between the base surface 1f and the mold M, the platen is located directly below the center of gravity O _M in a state where the mold M is suspended or more directly below the center of gravity O _M. If the roller member 11 is arranged immediately below the position close to the second side, the mold M stands up just by lowering the mold M, so that the distance between the two platens 2 is wide. even in situations placing a mold M in the vicinity of the wall can be a side F ₂ of the mold M is placed the mold M so as to be parallel to the platen side 2f. For this reason, it is not necessary to use precision equipment, such as a shock absorber.

  Therefore, according to the present invention, it is possible to provide a new workpiece installation apparatus and workpiece installation method that can install the mold M easily and in a short time while suppressing costs, and that has a wider application range. Can do.

  In particular, if the roller member 11 is detachably arranged with respect to the base surface 1f (injection molding machine) as in the installation device of the present embodiment, the roller member 11 can be changed to correspond to various molds M. Can do.

  Further, as in the present embodiment, if the roller member 11 is held rotatably and movable by the slit 13s formed in the side wall 13 of the main body 12, the mold M can be easily made with respect to the vertical wall by unitization. In addition to being able to be arranged in parallel, the roller member 11 can ensure a large amount of movement for raising the mold M by moving along the slit 13s. The member 11 can be arranged in parallel to the platen 2 without changing.

Furthermore, as in the present embodiment, the main body 12, and the road surface F _r of the roller member 11 to roll, slit 13s is formed with extending along the road F _r stands up from both sides of the road F _r and two side walls 13 are provided, the shaft 11a which projects from the side surface of the roller member 11 be to penetrate the slit 13s, when the roller member 11 shall movably held along the road surface F _r, By further simplifying the configuration for holding the roller member 11 so as to be slidable, further cost reduction is realized.
