Description

Technical Field

[0001] This utility model relates to the field of automotive stamping technology, and in particular to a mold for forming automotive stamping parts with anti-springback properties. Background Technology

[0002] Automotive stamping forming molds refer to the molds used in the automobile manufacturing process to process metal sheets into automotive parts of specific shapes and sizes through stamping.

[0003] Existing automotive seat side panel forming molds generate excess scrap during use. If the residual waste is not cleaned up in time, it will affect subsequent processing. Traditional automotive seat side panel forming molds cannot automatically clean up the residual scrap, which requires manual cleaning, which is time-consuming and labor-intensive.

[0004] An existing patent (publication number: CN218340824U) relates to a molding die for an automotive seat side panel in the field of automotive stamping die technology. A lead screw is rotatably connected to one side of the support frame. The end of the lead screw is fixedly connected to the output end of a motor. A slider is threaded onto the surface of the lead screw. A dust collection box is fixedly installed on the bottom surface of the slider. A vacuum cleaner is embedded in one side of the dust collection box, and a suction pipe is fixedly connected to one side of the dust collection box. A suction hopper is fixedly installed at one end of the suction pipe. Through the vacuum cleaner and the dust collection box, the suction hopper can clean the residual scrap material on the top of the processing table. By turning on the motor, the dust collection box moves back and forth at the bottom of the lead screw, increasing the area for cleaning residual scrap material and facilitating user operation.
