Abstract

A molded blank reshaping die comprises an upper die body and a lower die body. The upper die body comprises an upper die base body, an upper die insert and at least one pair of shovel bases. The upper die insert is vertically and movably installed on the lower portion of the upper die base body, a prepressing spring is arranged between the upper die insert and the upper die base body, and the shovel bases are fixedly installed at the lower end of the upper die base body. The lower die body comprises a lower die base body, a lower die insert and at least one pair of sliding blocks. The lower die insert is installed on the upper portion of the lower die base body, and the sliding blocks are arranged on the upper surface of the lower die base body in a relatively sliding mode. The shovel bases and the sliding blocks are arranged in a one-to-one correspondence mode. When the upper die and the lower die are folded, the upper die base body drives the upper die insert to press downwards to form a molded blank through the prepressing spring, the lower die insert on the lower die base body upwards abuts against the molded blank, the shove bases drive the corresponding sliding blocks to move from outside to inside in pairs to inwards compress the molded blank from the outside. The molded blank reshaping die can conduct efficient and accurate reshaping on the molded blank.
