Injection mold holder: the core component in the production of plastic and rubber products

The injection mold holder is an indispensable core component in the production of plastic and rubber products. This paper will introduce the concept, classification, application scenario, design principle and manufacturing process of injection mould frame in detail, as well as its importance in the production process of plastic and rubber products.

First, the basic concept and classification of injection mold frame

An injection mold holder, also known as an injection mold, is a special tool for the production of plastic and rubber products. It is mainly composed of mold cavity, pouring system, cooling system, ejecting device and other parts. According to the structural characteristics of the mold, the injection mold frame can be divided into the following categories:

1. The second plate mold: composed of the upper template, the lower template and the mold cavity, it is one of the most widely used injection mold frames.
2. Three plate die: an intermediate plate is added on the basis of the two plate die, which is used to control the opening and closing of the mold cavity.
3. Hot runner mold: Using hot runner technology, multi-color or co-injection can be achieved, mainly used for the production of complex plastic products.
4. Gas assisted injection mold: improve the internal structure and appearance of plastic products by introducing gas, suitable for the production of large plastic products.
