Convex hull die structure for preventing product adhesion

The convex hull die structure capable of preventing the product from being adhered comprises a convex hull structure which is correspondingly arranged between an upper die and a lower die and used for forming a square boss formed by stamping the product, the convex hull structure comprises a lower die plate used for bearing the product, a lower die plate forming groove matched with the square boss is formed in the lower die plate, and the convex hull structure corresponds to the lower die plate forming groove. A forming punching needle is correspondingly arranged on the upper die, the end of the forming punching needle is in a spherical shape, the forming punching needle is used as a punching spherical groove forming part different from a square boss, and a convex hull die forming structure which is different in punching boss and groove shape and capable of effectively preventing products from being adhered after being stacked is formed through combination. 本实用新型防止产品粘连的凸包模具结构，包括对应设置于上模和下模间的，用于产品冲压方形凸台成形的凸包结构，
