Mold stripping structure with sliding blocks for mold

Abstract

The invention discloses a mold stripping structure with sliding blocks for a mold. The structure comprises a large sliding block, a small sliding block, a shoveling machine and a plurality of guide rods, wherein a mounting groove is formed in the center of the large sliding block, the shoveling machine is arranged in the mounting groove, the other end of the shoveling machine extends out of the mounting groove of the large sliding block, an obliquely-downward notch is formed in the end, extending out of the mounting groove of the large sliding block, of the shoveling machine, an obliquely-downward guide rail is arranged on the notch, the small sliding block is arranged on the obliquely-downward guide rail in a sliding mode, a plurality of oblique inserting grooves are further formed in thelarge sliding block, and the corresponding oblique guide rods are inserted into the inserting grooves. The structure is simple, high in adaptability, and capable of guaranteeing smooth demolding of acomplex structure; the large sliding block slides in the corresponding direction, and in the sliding process of the large sliding block, the small sliding block obliquely moves downwards, and therefore demolding of a back mechanism is achieved, then the large sliding block continues to slide, and therefore demolding of the side edge mechanism is achieved; and in the process that the small slidingblock moves downwards, a product is separated from the small sliding block, and therefore smooth demolding is achived.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a mold ejection structure with slide blocks for molds. Background technique [0002] Injection molds are mainly used for injection molding plastic products with various structures, but demoulding after injection molding is always a problem. In particular, plastic products have relatively complex internal structures, such as the position of the bone position is reversed, and cannot be released from the mold. Traditional plastic products complete the demoulding action, usually through ordinary ejection mechanisms or ejection mechanisms. But these mechanisms are all difficult to realize the demoulding action of the plastic product of this kind of structure. [0003] For example, the general structure of some existing ejection mechanisms is very complicated, and it is necessary to design an oil cylinder to provide the power source of the inclined ejection mechanism, so that it is nece...

AI Technical Summary

Problems solved by technology

It mainly uses the secondary ejection action of the first elastic element and the second elastic element to prevent the product from being damaged and forcibly release the mold, but this structure cannot complete the mold release under the request of the reverse buckle
