Description

A stamping die for a washing machine housing

Technical Field

The utility model belongs to the technical field of washing machine production equipment, and in particular relates to a stamping die for a washing machine case.

Background Art

Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

After searching, the Chinese utility model patent application document with Chinese patent authorization announcement number CN213317214U discloses a new type of multi-purpose stamping die for anti-fracture washing machine box, including a bottom plate, a heating unit, a pushing unit, a fixed column and a top plate. The bottom plate and the top plate are installed with the stamping machine, and the material is placed on the top of the lower mold. The air pump and the heating wire are started to heat the air inside the air pipe. The air pump sprays hot air to the material through the air outlet to heat the material. Then the stamping machine is started to press the top plate downward, so that the punch at the bottom end of the top plate presses the material. The inner guide column on the front side of the bottom end of the top plate is slidably connected with the top of the outer guide column, and the telescopic rod is pulled to adjust the height of the limit sensor. After the material is pressed, the electric push rod is started, and the push plate at the top end of the electric push rod pushes the stamped material out of the lower mold.

With respect to the above-mentioned related technologies, the punch provided in the stamping device cannot effectively stamp the housing during stamping, which affects the stamping quality of the housing. Therefore, it is urgent to design a stamping die for a washing machine housing to deal with these problems.
