Description

Technical Field

[0001] The utility model relates to the technical field of mold equipment, in particular to a mold for processing a bidirectional connection structure. Background Art

[0002] Stamping dies, commonly known as cold stamping dies, are specialized equipment used in the cold stamping process to process materials (metal or non-metal) into parts or semi-finished products. Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to the material at room temperature, causing it to separate or plastically deform, thereby producing the desired part. Thin sheet parts are among the most common parts in our lives, including standard and non-standard gaskets, washers, friction plates, and templates.

[0003] The existing production technology is to first stamp the parts to stamp out the initial shape of the buckle, and then stamp and bend them again to complete the production of the buckle. The whole process requires two stampings and when preparing for the second stamping, the workpiece needs to be placed and positioned manually, which greatly affects work efficiency. In addition, it is difficult to overlap the two stampings and it is easy to deviate, resulting in defective products. Utility Model Content
