[0002] In the process of producing automobile gearbox guard plates, stamping is usually used to make them. In this process, a stamping die is used. The stamping die is a device that applies pressure to the material to separate or plastically deform it, thereby obtaining the required parts.

[0003] At present, after the stamping die completes the stamping of the gearbox template, it is difficult to quickly remove the gearbox guard plate because the gearbox guard plate is tightly attached to the inner wall of the lower die. The existing mold usually uses an electromagnet to suck the finished product out of the lower die, but the electromagnet is easily separated from the finished guard plate under a large pulling force, which is not conducive to the use of operators and reduces the demoulding efficiency of the finished guard plate. In addition, during use of the existing mold, the lower mold is usually riveted to the top of the base, which makes it difficult to quickly disassemble and assemble the lower mold from the base, making it inconvenient to perform regular maintenance on the lower mold, reducing the convenience of the mold.
