Technical Field

[0001] This utility model relates to the field of punching mold technology, and in particular to an automatic cleaning punching mold. Background Technology

[0002] A punching die is a tool used to create holes in materials such as metal or plastic. It typically includes an upper die, a lower die, a template, a pressure plate, and guide pillars. Punching dies are a type of die, specifically belonging to the category of stamping dies.

[0003] After the metal material is placed on the drilling die, the drill bit is usually pushed down by the hydraulic push rod to drill through the workpiece. However, after the workpiece is drilled, dust and burrs will be generated at the drilling position, which will affect the quality of the product. Additional cleaning is required afterward, which is difficult and increases production costs. Utility Model Content
