Plastic injection mold based on heat dissipation

Abstract

The invention provides a plastic injection mold based on heat dissipation. The plastic injection mold comprises a mold structure, wherein a heat dissipation structure is arranged on the outer side surface of the mold structure; a fan structure is arranged at the top end of the mold structure; a pesticide spraying structure is mounted at the bottom end of the fan structure; a one-way structure is mounted at the lower end of the pesticide spraying structure; a discharging structure is arranged between the one-way structure and the pesticide spraying structure; the fan structure comprises a fan box and a mounting hole; the fan box is arranged at the top end of the mold structure; a filter screen is arranged at the top end of the fan box; the mounting hole is formed in the front end of the fanbox; an air cavity is formed in the fan box; the air cavity is in a state of gradually reducing from back to front; the air cavity extends forwards to the mounting hole; the filter screen capable offiltering a part of impurities is arranged at the top of the fan box; and the air cavity at the lower end of the filter screen is in an inward contraction state, so that the entering air speed is higher.

Description

technical field [0001] The invention belongs to the technical field of injection molds, and more specifically relates to a heat-dissipating plastic injection mold. Background technique [0002] Plastic injection molding, which is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automatic operation, various designs and colors, simple to complex shapes, large to small sizes, accurate product sizes, easy replacement of products, and complex shapes. Parts, injection molding is suitable for mass production and complex-shaped products and other molding processing fields. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product. method. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods. [0003] ...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a heat-dissipating plastic injection mold to solve the problem that the existing mold will have a large amount of heat when it is taken out, so that the injection mold cannot be taken out quickly, and the inner wall of the mold after taking out will also have residues. Certain high temperature, if used for a long time will cause the phenomenon of staining
