Description

A computer shell mold with secondary ejection

technical field

The utility model relates to the field of plastic moulds, in particular to a computer shell mould with secondary ejection.

Background technique

Molds, various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. In short, molds are tools used to make molded articles , This kind of tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the molded material; most of the mold ejection structures on the market are one-time ejectors. However, when the glue surface facing the product is not on the same plane, the force of the product is uneven when the product is ejected at one time, and the relatively high glue position is difficult to fall off. It leads to the deformation or damage of the product, resulting in the aesthetics of the finished product and the waste of raw materials, and the residual glue sticks to the mold core, which requires the operator to clean the mold core before it can be put into production again, which affects the production efficiency. Computer shell mold for secondary ejection.
