Types of automobile mould

In a broad sense, “automobile mould” is the general name of mould for manufacturing all parts of automobile, such as injection mould, stamping mould, forging mould, casting wax mould, glass mould, etc. This paper introduces the most important plastic mould, casting mould and stamping mould in automobile mould.

1. Plastic mold

According to the different processing methods of plastic parts, automobile plastic mould can be divided into injection mould, compression mould, transfer mould and extrusion mould. Plastic molds are used to make most of the plastic parts in automobiles, such as bumpers, door handles, seat decorative side plates, etc,.

2. Casting mold

According to the purpose and complexity of the parts, the automobile casting mold can be divided into two categories: Automobile complex parts casting mold and automobile common parts casting mold. The automobile cover casting die is often used to make the blanks of complicated parts such as engine cylinder block, engine cylinder head, clutch shell, etc., while the automobile common parts casting die is used to make the blanks of simple parts such as engine connecting rod.

3. Stamping die

Stamping parts on automobile body are generally divided into covering parts, beam frame parts and general stamping parts. The stamping parts that can clearly represent the image characteristics of the automobile are automobile cover parts. Therefore, the more special automobile die can be called “automobile cover stamping die”, which is short for automobile cover stamping die, such as front door outer plate trimming die, front door inner plate punching die, etc. All the metal covers on the automobile, such as the engine cover, heat shield, etc., need to be made by the automobile stamping die.

After comparing and analyzing the processing parameters of the above three kinds of dies with the process characteristics of the three kinds of processes introduced in this paper, it is not difficult to find that the stamping dies are not suitable for manufacturing with 3D printing technology due to their high-strength characteristics, but in their R & D and design stages, 3D printing technology can be used to assist design, so as to shorten the R & D cycle and reduce the R & D cost. 3D printing technology can be used in the design, development and production of plastic mold and casting mold.
