Automobile mold, in a narrow sense, is the general term for stamping all stamping parts of the automobile body. That is, "car body stamping die". For example, the top cover flanging die, beam strengthening plate pressing die, etc.

1. The drawing die is a die that makes the sheet blank into an open hollow part, or makes the hollow part further change its shape and size.
2. The bending die makes the sheet blank or other billet bend and deform along a straight line (bending line), so as to obtain a mold of the workpiece with a certain Angle and shape
3. Forming die is the blank or semi-finished workpiece directly copied and formed according to the shape of the convex and concave die, and the material itself only produces local plastic deformation of the die. Such as expansion die, shrink die, flaring die, undulating forming die, flanging die, shaping die, etc.
4. The die is blanked along the closed or open contour line to make the material separate the die. Such as blanking die, punching die, cutting die, incision die, cutting die, cutting die, etc.
2. Classification according to the degree of process combination
1. The progressive die (also known as continuous die) has two or more stations in the feeding direction of the blank, and completes two or more stamping processes at different stations in one stroke of the press.
2. The composite die has only one station, and in one stroke of the press, two or more stamping processes are completed at the same station at the same time.
3. Single process die in one stroke of the press, only one stamping process die is completed.
According to the product processing method classification According to the different processing methods of the product, the mold can be divided into five categories such as punching mold, bending mold, drawing mold, forming mold and compression mold.
1. Forming die: refers to the use of various local deformation methods to change the shape of the wool embryo, the form of convex forming die, rolling edge forming die, necking forming die, hole flange forming die, round edge forming die.
2. Bending die: The flat wool embryo is bent into an Angle shape, depending on the shape, accuracy and production of the part, there are a variety of different forms of die, such as ordinary bending die, CAM bending die, curling die, arc bending die, bending die and bending die.
3. Punching die: It is used to complete the work by shearing. Commonly used forms are cutting die, blanking die, punching die, trimming die, finishing die, drawing die and punching die.
4. Drawing mold: Drawing mold is to make flat wool embryo into a seamless container with bottom.
