Strengthened stamping die and manufacturing method

The invention discloses a strengthened stamping die. A strengthening rib network is arranged inside the cantilever. When the cantilever part is formed on the stamping die, the toughness of the cantilever is guaranteed and the problem of breakage of the cantilever component under repeated stress is solved; the mechanism is used for stamping dies needing the cantilever to press materials. The invention also provides a manufacturing method of the strengthened stamping die; a main rib and an auxiliary rib are integrally welded to form the strengthening rib network; the strengthening rib network is fixed in the cantilever, and then pouring is performed; after the poured material is cooled, the casting is bonded with the strengthening rib network; finally, a limiting block and a pressure source are mounted on the casting. The strengthened stamping die is capable of guaranteeing the service life of the cantilever, the pressing component and the shaping component, and also has the advantages of simple structure, high practicability, safety and reliability, and the like.
