Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a side punching mold structure. Background Technology
[0002] In modern manufacturing, molds such as stamping dies, forging dies, and die-casting molds are essential tools for the industrial production of various parts. Stamping is a pressure processing method that uses stamping dies mounted on a press to apply pressure to raw materials at room temperature, causing the materials to separate or plastically deform, thereby obtaining the desired parts. Punching dies are molds that punch various shaped holes into raw materials.
[0003] As a commonly used type of mold, punching molds mainly use a punch to cut waste material from the workpiece from top to bottom. However, this type of punching mold cannot punch the side walls of some parts and requires the replacement of the punching device for further processing. The punching efficiency is low, so the existing technology needs to be improved. Utility Model Content
