Vacuum die-casting die of large thin-walled structure part

Abstract

The invention discloses a vacuum die-casting die of a large thin-walled structure part. The vacuum die-casting die comprises a lower die plate. A lower die seat is mounted at the top of the lower dieplate. An upper die seat is mounted at the top of the lower die seat. An upper die plate is mounted at the top of the upper die seat. A die cavity groove is formed in the top of the lower die seat. Athird groove is formed in the bottom of the lower die seat. The die cavity groove communicates with the third groove. A first groove is formed in the front surface of the lower die plate, and a threaded pipe is arranged in the first groove. According to the vacuum die-casting die, a die cavity shell is placed on a supporting plate, through motor drive, under cooperation of a limiting plate to sliding plate limiting, two sliding plates drive the supporting plate upwards, the supporting plate drives the die cavity shell to move upwards, then the die cavity shell is mounted into the die cavity groove, and the stabilization effect during mounting of the die cavity shell is improved; and a large amount of manual operation is avoided, time consumption of die cavity replacement is reduced, and dismounting and replacement are convenient for die cavity mounting.

Description

technical field [0001] The invention relates to the technical field of metal casting molds, in particular to a vacuum die-casting mold for large thin-walled structural parts. Background technique [0002] Die-casting mold is a tool for casting metal parts, a tool that completes the die-casting process on a special die-casting die forging machine. The basic process of die-casting is: the molten metal is first cast at a low or high speed and filled into the cavity of the mold. The mold has a movable cavity surface, which is forged under pressure during the cooling process of the molten metal, which eliminates the shrinkage of the blank. Loose defects also make the internal structure of the blank reach the broken grains of the forged state. The comprehensive mechanical properties of the blank have been significantly improved. During the production process of different parts, the mold cavity inside the mold needs to be taken out and replaced. The existing mold cavity requires w...

Problems solved by technology

The comprehensive mechanical properties of the blank have been significantly improved. During the production process of different parts, the mold cavity inside the mold needs to be taken out and replaced. The existing mold cavity requires workers to spend a lot of time to replace it, and the position of the mold cavity is changing. It is not conducive to its positioning, resulting in the deviation of the mold cavity, resulting in easy errors. Therefore, a vacuum die-casting mold for large thin-walled structural parts is proposed
