According to the mold structure, such as single-process mold, compound mold, etc.
According to the object of use, such as automobile panel die and motor die;
Classification according to the properties of processing materials, such as molds for metal products and molds for nonmetal products;
According to the classification of 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 not fully reflect the structure, forming process characteristics and use functions of various molds. 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 manufacturing methods.
1
Stamping die (stamping die)
Punching die (punching with less waste, trimming, smooth punching, deep hole punching fine punching die, etc.). ), bending die, drawing die, single-process die (blanking, 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
Die, extrusion die and injection mold (vertical, vertical and angular injection mold); Thermosetting plastic injection mold, extrusion molding mold (pipe, flat mold with film, etc. ), foam molding mold, low-tool foam injection mold, blow molding mold, etc.
