Pressing-casting die

Abstract

The invention discloses a die-casting mold, which comprises a top mold frame, a pressure chamber cavity is opened on the front of the top mold frame, a sealing box is fixedly connected to the top of the top mold frame, and both sides of the top of the sealing box are A through hole is opened, and the top of the top mold frame is fixedly connected with a motor in the inner cavity of the sealed box, the rotating shaft of the motor is provided with a first spur gear, and the inner cavity of the sealed box is located A cross bar is arranged above the top of the cross bar, and the surface of the cross bar is covered with a cover plate, and the top of the cover plate is fixedly connected with the top of the inner cavity of the sealed box. The invention can drive two threaded pipes to rotate at the same time, so that the threaded rod moves vertically, and the threaded rod drives the pushing block to move vertically, and the two threaded rods are fixedly connected with the pushing block, the connection is stable, and the stability of the pushing block is enhanced, avoiding The inclination of the pushing block during the die-casting mold improves the quality of the finished product and is convenient for people to use.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a die-casting mold. Background technique [0002] Die-casting mold is a method of casting liquid die forging, a process completed on a special die-casting die forging machine, its basic process is: the metal liquid is cast into the cavity of the mold at low or high speed, and the mold has The active cavity surface, which is pressurized with the cooling process of the molten metal, not only eliminates the shrinkage cavity and porosity defects of the blank, but also makes the internal structure of the blank reach the broken grains of the forged state, and the comprehensive mechanical properties of the blank are significantly improved. improve. [0003] The shape of the die-casting mold cavity is fixed, so only one type of die-casting product can be produced, that is, a die-casting mold must be produced for each type of die-casting product, and the cost is very high. For ...
