Description

Technical Field

[0001] The utility model belongs to the technical field of stamping dies and relates to a stamping die capable of automatic demoulding. Background Art

[0002] Stamping dies are special process equipment used in cold stamping to process materials (such as metals or non-metals) into parts or semi-finished products. This process mainly uses the die installed on the press to apply pressure to the material to separate or plastically deform it, thereby obtaining the required parts. If the stamping die cannot be quickly demolded after stamping, a series of problems will arise, which will have a significant impact on production efficiency, product quality and production costs.
