HOT STAMPING DEVICE THAT PRE COOLES BLANK BEFOR FORMING

摘要

According to an embodiment of the present invention, a hot stamping device performing hot stamping and quenching a blank heated at a first set temperature range forms a molded product by pressing a lower surface and an upper surface of the blank and includes a lower mold and an upper mold which are simultaneously formed and quenched. On a molded surface of the lower mold or the upper mold, air is injected on a part of the blank loaded on the upper mold and the lower mold such that an air injecting hole forming an air cooling portion can be formed. Thus, the hot stamping device of the present invention is able to easily prevent formation of crack or necking in the molded product.
