Zinc alloy die-casting die

Abstract

The invention discloses a zinc alloy die-casting die. The zinc alloy die-casting die comprises a lower die holder and an upper die holder, wherein a die cavity is formed in the middle end of the top of the lower die holder, first preformed grooves are respectively formed in an inner cavity of the lower die holder and are located in the left and right sides of the die cavity, a first electric telescopic rod is fixedly connected to the inner sides of the first preformed grooves, and a first movable die holder is fixedly connected to the tail end of the first electric telescopic rod. According tothe zinc alloy die-casting die, the first preformed grooves are respectively formed in the inner cavity of the lower die holder and are located in the left and right sides of the die cavity, and second preformed grooves are respectively formed in the left and right ends of an inner cavity of the upper die holder, so that under the action of the first electric telescopic rod and the first movabledie holder as well as a second electric telescopic rod and a second movable die holder, the size adjusting requirement of people on the die-casting die can be satisfied, and the problems that the sizeof an existing die-casting die is fixed, different types of corresponding dies need to be used when die-casting operation needs to be performed on products of different sizes by people and the use ofpeople is inconvenient are solved.

Description

technical field [0001] The invention relates to the technical field of die-casting molds, in particular to a zinc alloy die-casting mold. Background technique [0002] Die-casting mold is a method of casting liquid die forging. It is a process completed on a special die-casting die forging machine. Its basic process is: the metal liquid is first filled into the cavity of the mold by low-speed or high-speed casting, and the mold There is a movable cavity surface, which is forged under pressure during the cooling process of the molten metal, which 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. However, the size of the existing die-casting molds is fixed. When people need to die-cast products of different sizes, they need to use different types of corresponding molds, whi...
