New energy vehicles refer to the use of unconventional fuels as power sources (or the use of conventional vehicle fuels, the use of new on-board power devices), the integration of advanced technologies in vehicle power control and drive, and the formation of advanced technical principles and new technologies. 1. The new structure of the car, the brake disc of the new energy car is simply a round plate, and it also rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When the brake is applied, it clamps the brake disc to slow down or stop the car. The braking effect of the brake disc is good, and it is easier to maintain than the drum brake. When the brake disc is produced, it is generally molded by casting.

A mold is a tool used to make shaped objects. This tool is composed of various parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. It is usually used in industry to obtain various molds and tools for required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping, stretching and other methods.

For example, the Chinese patent whose authorized notification number is CN112191745B discloses a stamping die specially used for producing automobile brake discs, which relates to the technical field of automobile parts processing equipment.
