Description

Simultaneously-ejecting thread mold

Technical Field

The utility model relates to a simultaneously ejecting thread mould belongs to mould processing technology field.

Background

The die is various dies 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 shape an article, the tool being made up of various parts, and different molds being made up of different parts. The method realizes the processing of the appearance of the article mainly by changing the physical state of the formed material, and the article is called as 'industrial mother'.

The thread mould is mainly a device for producing parts with certain thread shape requirements.

After the part is formed, the thread die adopts an ejector pin to realize demoulding. When the ejector pins are used for demoulding, the ejector pins are in contact with a product, a certain acting force is applied to the product, the product is forcedly separated from the mould, the product is deformed to a certain degree at the contact position of the product and the ejector pins, and the quality of the product is even affected in severe cases. And the existing mold can only remove one product at a time when removing threads, and the efficiency is lower.
