The upper die and the lower die are respectively provided with an upper die forming block and a lower die forming block for forming during stamping. During stamping, the workpiece is prone to sticking to the upper die forming block. In addition, during repeated stamping, the upper die forming block and the lower die forming block are worn, which is inconvenient to replace or repair. The existing device still has some defects; for example;

[0003] The existing patent publication number is CN211679626U, which is a stamping die for automobile hardware processing. When the technology is used, the parts to be pressed are placed in the lower die, and then the pushing device is started. The hydraulic cylinder on the pushing device will push the telescopic rod. Because the telescopic rod and the movable plate are fixedly connected, and the upper die is arranged on the movable plate, the telescopic rod will drive the movable plate to move downward. Because the upper die and the lower die are arranged to match, the lower die will be pressed, and the lower die is arranged on the top surface of the lower die placement plate, and a shock absorbing device is also arranged at the bottom of the lower die placement plate, and the shock absorbing device is arranged in multiple groups, so when pressing, the load-bearing column will bear the impact force, thereby pressing the movable block, and the movable block compression spring relieves the impact force, and a shock absorbing pad is arranged on the bottom surface of the lower die placement plate, and a protective pad is arranged on the top surface of the base, which can protect the lower die placement plate and the base, and can prevent the base and the lower die placement plate from colliding, and the lower die is connected to the lower die placement plate by screws, and the upper die is connected to the movable plate by screws.

[0004] The above device has some problems. It is troublesome to use. The stability of the telescopic rod is poor when it is moved. The design of the shock-absorbing pad leads to poor stamping effect. The mold has poor use effect and is not convenient to disassemble and replace.

[0005] Therefore, we propose a stamping die for automobile hardware that is easy to replace in order to solve the above-mentioned problems. Utility Model Content
