[0002] Home appliance sheet metal molds are molds specifically used to process sheet metal parts required by the home appliance industry. During the production process of existing home appliance sheet metal parts, stamping is usually used to stamp the sheet metal parts into specific shapes for subsequent home appliance assembly.

[0003] During the stamping process of sheet metal parts through stamping dies, the sheet metal parts are placed inside the die, and then the punching head is started to quickly stamp the surface of the sheet metal parts to form a specific shape, which is convenient for subsequent assembly of home appliances.

[0004] In the current prior art, when existing sheet metal parts are stamped by stamping dies, the punching head will experience severe wear under long-term stamping, and the punching head needs to be replaced. However, the punching head is usually welded, which makes the replacement of the punching head more cumbersome, thereby reducing the stamping efficiency of the sheet metal parts.
