Abstract

The invention discloses a liquid-filling forming mold which comprises a male mold, a female mold, a blank holder and a water retaining plate, wherein the female mold is fixedly arranged; a cavity is formed in the female mold; a liquid-filling cavity is formed in the bottom of the cavity; the male mold is movably arranged above the female mold; one side of the male mold close to the female mold has a shape matched with the cavity; a water inlet pipe is arranged on the female mold; a first end of the water inlet pipe is communicated with the liquid-filling cavity; the water retaining plate is mounted on one side of the female mold close to the male mold; the water retaining plate surrounds an opening position of the cavity; the blank holder is movably arranged above the female mold; a side surface of the male mold is connected with the inner wall of the blank holder in a sliding manner. The liquid-filling forming mold provided by the invention can eliminate phenomena of cracking, internal injury, scratching and the like caused by excessive local stamping force.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a liquid-filled forming mold. Background technique [0002] At present, the aluminum alloy outer panels of automobiles are mainly formed by cold stamping dies. [0003] In prior art, please refer to figure 1 , figure 1 It is a structural schematic diagram of a stamping die disclosed in the prior art, which includes an upper die 1' and a lower die 2', through the mutual cooperation of the upper die 1' and the lower die 2' to form a large stamping force to directly press the die to be stamped Stamping parts. [0004] In the process of cold stamping, due to the low rigidity of the aluminum alloy itself, in the process of direct cold stamping, cracking, hidden damage, scratches, etc. . [0005] How to reduce the phenomenon of cracking, dark damage, scratches and the like produced in the stamping process of aluminum alloy is one of the important problems to be solved urgently in th...
