In short, molds are tools used to make molded products. This 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 molding material. Known as the "mother of industry".
According to the processing object and processing technology can be divided into:
Mould for processing metal; Non-metallic and powder metallurgy processing dies. Including plastic molds (such as two-color molds, compression molds and extrusion molds, etc.). ), rubber mold and powder metallurgy mold. According to the structural characteristics, the die can be divided into plane blanking die and cavity die with space. Generally, molds are single-piece and produced in small batches.
Extended data:
A key part of die fittings is die spring.
1. Die springs include: Japanese standard die springs, German standard die springs, springs and polyurethane springs. Usually, the die spring refers to a rectangular die spring.
2. Die springs are widely used in stamping dies, metal die-casting dies, plastic dies, other elastic motion precision mechanical equipment, automobiles and other fields.
3. Chromium alloy steel is usually used as the material of die spring. Chromium alloy spring steel has the characteristics of high temperature resistance, high hardness and long service life.
4. Rectangular die spring has the characteristics of small volume, good elasticity, high rigidity and high precision. It is made of rectangular material, and the surface color separation spraying (electroplating) distinguishes different loads, which is beautiful in appearance.
