[0002] Stamping dies are also a type of mold used for batch molding of parts. The biggest difference between them and injection molds and die-casting molds is that the material does not need to be heated and softened before molding, and can be molded at room temperature, so it has the advantages of saving energy, no need to consider the cooling and solidification of the material during molding, and no need to set up an oil cooling or water cooling system.

[0003] The existing rear support plate stamping module of the automobile wheel cover outer panel requires an additional plate cutter to pre-process the plate and cut it into a suitable shape before stamping the plate, which wastes extra time; the existing rear support plate stamping module of the automobile wheel cover outer panel has hard contact between the stamping block and the stamping seat and lacks a buffer and wear-resistant structure, so it is very easy to wear and affect the service life of the stamped parts. Therefore, in view of the above problems, a rear support plate stamping module of the automobile wheel cover outer panel is proposed. Summary of the invention
