Technical Field

[0001] The utility model relates to the technical field of stamping dies, and particularly relates to a stamping die for mechanical parts. Background Art

[0002] A die is various molds and tools used in industrial production to obtain required products by means of injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, etc. A stamping die is a special process equipment for processing materials into parts in cold stamping. It is called a cold stamping die. Stamping is a pressure processing method that applies pressure to materials by using a die installed on a press at room temperature to cause separation or plastic deformation, so as to obtain required parts.

The adopted solution is: including an upper module and a lower module located directly below the upper module. A compression through-hole is penetrated and opened in the middle position on the upper side of the upper module. A pressing module is arranged inside the compression through-hole. L-shaped blocks are arranged at opposite ends of two moving holes in the same left-right direction. Upper through-holes are penetrated and opened at the four corners of the upper end of the upper module. Lower through-holes are penetrated and opened at positions corresponding to the upper through-holes on the upper end of the lower module.
