Description

Automatic ejection demoulding mechanism for fixed die

Technical Field

The utility model relates to the technical field of mold, specifically an automatic ejecting demoulding mechanism of cover half.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother". The types of the die are various, and the die can be divided into the following parts according to processing objects and processing technologies: and (4) processing a metal die. Processing non-metal and powder metallurgy dies. Including plastic molds (e.g., two-color molds, compression molds, extrusion molds, etc.), rubber molds, powder metallurgy molds, and the like. According to the structural characteristics, the die can be divided into a plane blanking die and a cavity die with a space. The mold is generally one-piece and produced in small batches.

The existing fixed die ejection demoulding mechanism increases the contact area of a rear die core and a product, the product is left in the rear die core through static friction force during die opening, and then the product is ejected out by an ejector pin of the rear die.
