technical field

The utility model relates to the technical field of stamping dies, in particular to a stamping die which is convenient for demoulding.

Background technique

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 product. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of molds. The level of mold design and manufacturing technology is one of the important symbols to measure the level of a country's product manufacturing, which largely determines the quality, efficiency and new product development capabilities of products.

In existing stamping dies, when the contact area between the upper and lower dies and the parts is large, the parts are prone to sticking to the upper die or the lower die and are not easy to fall off.
