難いという問題点がある。To produce synthetic resin products with inwardly bent edges,
A pair of molds and a slide core for molding the inwardly bent edge are clamped together to form a cavity, and after injection molding a synthetic resin molding material into the cavity, the slide core is moved to open the mold. However, when using polyurethane resin for high-pressure reaction molding with extremely low viscosity as a molding material, such as urethane bumpers for automobiles, which are rapidly becoming popular in recent years, it is necessary to The viscous acid-containing resin molding material enters the fine slits formed on the joint surface between the mold and the slide core, causing burrs on the product.
Mold cleaning is not only necessary, but also prevents the synthetic resin molding material that has entered the minute gaps mentioned above from adhering firmly to the mold surface, making it impossible to move the slide core. There is a problem in that it requires a lot of work and is difficult to mass-produce high-quality products.

られることは全くない。With this structure, the other mold 2 is moved in the direction of one mold 1, the piston 9 of the suppressor 7 is advanced, the slide core 4 is moved, and the three molds are clamped. After clamping the molds, if the piston 16 of the pressing device 14 is advanced to bring the joint surface 13 between the slide core 4 and one of the molds into close contact, a joint is formed between the pair of molds 1 and 2 and the slide core 4. The cavity part 19 has an inwardly bent edge formed by the other mold 2 and the mold surface 5 of the slide core 4 connected to the upper end of the main body formed by the pair of molds 1 and 2, thereby forming a product. Therefore, if a low-viscosity synthetic resin molding material such as C polyurethane resin for high-pressure reaction molding is injected into the cavity 19 in this state, this type of molding material will have a low viscosity. Regardless of the case, the slide core 4 is of course pressurized by the press device 7 for mold clamping, and is also pressurized in the pressing direction of the press device 7, that is, in a direction perpendicular to the moving direction of the slide core 4. Since the joint surface 13 between the slide core 4 and one of the molds 1 is maintained in a close contact state by being pressurized by the suppressing device 14, the molding material injected into the cavity portion 19 is applied to this joint surface 13. Because it is molded and solidified without penetration,
Thereafter, the piston 16 of the pressing device 14 is retracted, and the piston 9 of the pressing device 7 is also retracted to move the slide core 4 backward, and then the other mold 2 is raised and molded in the cavity portion 19. The mold is opened with the inwardly bent edge remaining in the recess 3 of the other mold 2, and the product remaining in the other mold 2 that has finally risen is removed by ejecting pins or other similar methods. It is sufficient to release the mold using a mold release means.
Since the joint surface 13 is in close contact with the product after this mold release, almost no burrs can be seen, and the slide core 4 and mold 1
The movement of the slide core 4 is not hindered at all by the molding material adhering to the slide core 4.

A movable plate 39 is fixed, and the movable plate 39 is in contact with the lower surface of a mounting plate 37 connected to the other mold 22 via a connecting rod 38. When pressure oil is supplied from below the piston 36, the piston Since the movable plate 39 fixed to the upper end of the cylinder 36 is pressed against the mounting plate 37, the pressing force of the piston 36 is also applied to the joint surface 33 between the mold 22 and the slide core 24, causing the cylinder 35 and the piston 36 to slide. The core 24 is pressed in a direction perpendicular to its moving direction to form a joint surface 3 between the slide core 24 and the other mold 22.

動が妨げられるようなことは全くない。With this structure, the other mold 22 is moved in the direction of one mold 22, the piston 29 of the pressing device 27 is advanced, the slide core 24 is moved, and the three molds are clamped. After clamping the molds, if fluid pressure is applied to the pressing device 34 to bring the joint surface 33 between the slide core 24 and the other mold 22 into close contact with each other, a joint surface 33 is formed between the pair of molds 21, 22 and the slide core 24. The cavity portion 40 has a convex portion 2 of one of the molds 21 at the upper end of the main body formed between the pair of molds 21 and 22 and most of the slide core 24.
Since the inward bent edge formed by the mold surface 3 and the mold surface 25 of the slide core 724 are connected and have the same shape as the product, in this state, the mold surface 40 is
When a low-viscosity synthetic resin molding material is injected as in the case of the embodiment, the slide core 24 is of course pressurized by the mold clamping suppressing device 27, and the pressing direction of the pressurizing device 27 is That is, since the joint surface 33 between the slide core 24 and the other mold 22 is kept in close contact with each other by being pressurized by the suppressing device 34 that applies pressure in a direction perpendicular to the moving direction of the slide core 24, Since the molding material injected into the cavity 40 is molded without entering the joint surface 33, the cylinder 35 of the pressing device 34 is then moved back toward the moving plate 39, and the piston 29 of the suppressing device 27 is moved back. to move the slide core 24 to the supporting member 26 side together with the moving plate 39, and then move the other mold 22
The mounting plate 37 is raised along with the mounting plate 37, and the mold is opened while the product molded in the cavity 40 remains in the mold recess of one of the molds 21. Finally, the product remaining in one of the molds 21 is released to the general public. It is sufficient to release the mold using the existing mold release means, and the product after this mold release has almost no burrs because the joint surfaces are brought into close contact during injection, and the slide core 24 and mold 21 , 22 and the movement of the slide core 24 is not obstructed at all.

界にもたらすところ極めて犬なものである。As is clear from the explanation of the above-mentioned examples, the present invention does not cause bonding in products molded using a low-viscosity synthetic resin molding material, simplifies the deburring work, and has a low-viscosity synthetic resin molding material. Since the synthetic resin molding material does not adhere to the joint surface and impede the movement of the slide core, there is no need to frequently clean the mold, making continuous work possible, making mass production easier, and making molds easier. This pipe has various advantages, and has been introduced into the industry as a manufacturing method and equipment for synthetic resin products with inwardly bent edges suitable for manufacturing automobile bumpers, etc., using polyurethane resin for high-pressure reaction molding as a molding material. The results are extremely dog-like.
