New description: [New technical field] [0001] The present invention relates to a stamping die, in particular to a stamping die which can effectively prevent the scrap from jumping during the stamping process. [Prior Art] [0002] In the stamping production process, the scrap back is the most common bad phenomenon in the on-site production process. The so-called scrap rebound B is in the middle pressure process, from the stamping die to the stripper. During the complete opening process, when the stripper plate is not left of the product and the recessed formwork, the scrap generated by the stamping will be due to the positive air pressure below it, the upper negative air pressure (or vacuum 〃' and thus the double action of air pressure and oil viscosity. Adhesively sticking to the mold and then as the die punches up, it is stuck directly under the product hole, so that when the stripping plate leaves the lower die, under the multiple action, the product is detached from the concave template and adhered to the stripping plate. At the same time, the air pressure under the waste is still greater than the air pressure on the waste. The waste jumps to the concave surface with the product and causes the appearance of the product to be bad, which seriously affects the quality of the product and the efficiency of the processing and production safety. [New content] The purpose of this creation In order to overcome the deficiencies in the prior art described above, a stamping die capable of effectively preventing scrap back from jumping is provided.
