More Information
Summary:The utility model discloses a stamping die capable of improving the lapping-in rate of a large covering part. According to the stamping die capable of improving the lapping-in rate of the large covering part, the cross section of the periphery of an upper die is an arched curve which is oblique downwards from outside to inside, a middle molded surface is prevented from being deformed by means of arched surface compensation which is carried out on the periphery of the upper die, therefore, the primary molded surface lapping-in rate is effectively increased, and the production cycle is shortened.
