An injection molding die

Abstract

The invention relates to an injection molding and buried injection molding die set. The injection molding and buried injection molding die set comprises a dynamic die, and a stationary die which is matched with the dynamic die; the stationary die comprises a stationary die plate and a dynamic die core; the dynamic die comprises a dynamic die plate and a dynamic die core; the stationary die plate and the dynamic die plate form a complete die plate set; the stationary die core and the dynamic die core form a complete die core set; an embedding part which forms an integrated product with a part needing injection molding is also arranged in an inner cavity of the die core set; a sliding block for assisting to locate the embedding part is arranged between the die core set and the die plate set; the embedding part is arranged on the sliding block in a buckling manner; a corresponding locating groove is formed in the side locating surface of the sliding block, corresponding to the embedding part; a boss structure matched with the locating groove is arranged on the side locating surface of the embedding part; an initial locating structure for assisting to locate the embedding part on the sliding block is also added to the embedding part structure. According to the mode, the injection molding and buried injection molding die set has the advantages that the embedding part can be precisely located during molding according to the die structure design; in addition, the offset of the embedding part caused by the rebound deformation of the embedding part or the plastic cement flowing impact during molding can also be prevented, and thus the molding quality and precision can be greatly improved.

Description

technical field [0001] The invention relates to the field of injection mold equipment, in particular to an injection molding die set. Background technique [0002] Plastic injection molding is an excellent processing method for low-cost, high-volume production of plastic products, and it is also an indispensable processing technology for the development of high-tech products. Plastic has the advantages of easy formability, flexibility, and insulation; while metal has certain characteristics such as rigidity, strength, electrical conductivity, and heat resistance. The integrated product with matrix function and new function and meeting specific needs has become a hot spot in the field of injection molding in recent years. [0003] Submerged injection molding is also called injection molding or insert molding. There are many types of insert materials, not only metal can be used as insert material, but also other materials, such as cloth, paper, wire, plastic, glass, wood, et...

AI Technical Summary

Problems solved by technology

[0004] The main technical problem to be solved by the present invention is to provide an injection molding module, which has a reasonable design and a simple structure, and solves the problem that the precision of the product decreases due to the deviation of the insert during the molding process.
