Stamping dies for easy demoulding

Abstract

The invention discloses a stamping die facilitating die releasing. The die is used for stamping a part (4), a puncher pin matched with a lower die (2) is arranged on an upper die (1), a pressing plate (3) is arranged on the lower portion of the upper die (1), a lifting table (5) is arranged on the upper portion of the lower die (2), the opposite faces of the pressing plate (3) and the lifting table (5) are respectively and symmetrically provided with at least one groove (6), and compression springs (7) are arranged in the grooves (6) respectively. The compression springs are arranged on the pressing plate and the lifting table of the die, after stamping forming is completed, the part can be ejected and is disengaged from the die, the good die releasing effect is achieved, manual die releasing is not required, the production safety is good, and efficiency is high. In the stamping process, the grooves can reserve a space for the compression springs, the pressing plate can still tightly compress the part on the lifting table, the stamping forming effect cannot be affected, the integrally-formed structure is adopted by the pressing plate, the puncher pin and the upper die, machining is convenient, and stability is good.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a stamping die which is convenient for demoulding. Background technique [0002] Stamping processing in mechanical processing occupies an important position in the processing industry of the national economy. The stamping process is adopted, which has the advantages of high precision, high efficiency, good quality, material saving and low cost. Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. Stamping die is an indispensable process equipment for stamping production, and it is a technology-intensive pr...

AI Technical Summary

Problems solved by technology

[0003] In existing stamping dies, when the contact area between the upper and lower dies and the parts is large, the parts are prone to stick to the upper die or the lower die and are not easy to fall off. Manual detachment is required, the operation is dangerous and the processing efficiency of the parts is low
