According to the mold structure, such as single-process molds and compound dies;
according to the objects of use, such as automobile panel dies and motor dies;
classified according to the properties of processing materials, such as molds for metal products and molds for nonmetal products;
according to the mold manufacturing materials, such as cemented carbide molds; According to the process properties, such as drawing die, powder metallurgy die, forging die, etc.
Some of these classification methods can't fully reflect the structure of various molds, the characteristics of forming process and their functions. Therefore, a comprehensive classification method based on the technological properties and users of molds is adopted, and molds are divided into ten categories, as shown in Table 1, and can be divided into several subcategories or varieties according to mold structure, materials, use functions and mold making methods.
1
Stamping die (punching die)
Punching die (punching with little or no waste, trimming, smooth punching, deep hole punching, etc.), bending die, drawing die, single-process die (punching, bending, drawing, forming, etc.), compound die and progressive die; Automobile panel die, combined die, motor silicon steel sheet die
sheet metal stamping forming
2
plastic molding die
compression molding die, extrusion molding die, injection mold (vertical, vertical and angular injection mold); Thermosetting plastic injection mold, extrusion molding mold (pipe, flat film die, etc.), foam molding mold, low-tool tool bubble injection molding mold, blow molding mold, etc.
Plastic product forming plus Huangyan process (thermosetting and thermoplastic molding compound)
3
Die casting mold
Die casting mold for hot chamber die casting machine, die casting mold for vertical cold chamber die casting machine, die casting mold for Chen cold chamber die casting machine,. Non-ferrous metal (zinc, aluminum, copper, magnesium alloy) die-casting, ferrous metal die-casting die
non-ferrous metal and ferrous metal pressure casting forming process
4
forging die
forging die for die forging and large press, forging die for screw press, forging die for flat forging machine, rolling forging die, etc. All kinds of fasteners are cold heading dies, extrusion dies, wire drawing dies, liquid forging dies, etc.
