Description

Mould with automatic demoulding function

Technical Field

The utility model relates to an injection mold, in particular to mould with automatic drawing of patterns function.

Background

Injection molding is a tool for producing plastic products and also for giving the plastic products complete structure and precise dimensions, and injection molding is a processing method used for mass production of parts with complex shapes. Specifically, the plastic melted by heating is injected into a mold cavity from an injection molding machine at high pressure, and a formed product is obtained after cooling and solidification.

The existing injection mold generally comprises an upper mold and a lower mold, a mold cavity is formed between the upper mold and the lower mold, and hot-melt plastic can be adhered to the wall of the mold cavity after being cooled, so that the existing injection mold needs a worker to manually take out an injection product from the mold cavity during demolding, and the demolding procedure of the injection product can be completed. There is a risk of manually removing the injection-molded product from the mold cavity, for example: when the injection molding machine breaks down, the hands of workers can be clamped easily; and the manual taking-out mode also increases the labor cost and reduces the production efficiency.
