Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a drawplate press mold. Background Art

[0002] The drawplate press mold is mainly used for stamping and forming metal sheets. Especially in the production of metal molds, it can make the metal sheet undergo plastic deformation through the mold closing action of the upper and lower molds, so as to obtain workpieces with the required shapes and sizes.

[0003] After the material is formed in the drawplate press mold, it is usually manually demolded. The operation is very inconvenient, with a large labor intensity. And the difficult demolding will prolong the production cycle, thus reducing the overall production efficiency. Moreover, if the material is subjected to inappropriate forces or friction during demolding, it may cause scratches, deformation or damage to the product surface, affecting the quality and appearance of the product. At the same time, long-term manual demolding or forced demolding may cause wear or damage to the mold, shortening the service life of the mold and increasing the maintenance cost. In view of this, the present utility model is specifically proposed. Summary of the Utility Model
