Secondary ejection die-casting die

Abstract

The invention relates to the technical field of die-casting dies, in particular to a secondary ejection die-casting die which comprises a base, a fixed die is fixedly connected to the outer surface of the upper end of the base, a movable die is movably connected to the outer surface of the upper end of the fixed die, and a sprue gate is formed in the outer surface of the upper end of the movable die. Vertical plates are evenly distributed at the position, close to the edge, of the inner bottom of the fixed mold, a shaping block is arranged at the center of the inner bottom of the fixed mold, vertical grooves are evenly formed in the outer circle face of the shaping block, buckling grooves are evenly formed in the lower end of the outer circle face of the shaping block, and the buckling grooves communicate with the vertical grooves. And a die casting is arranged on the outer surface of the upper end of the shaping block. The second ejector rod rotates when moving upwards, so that the second ejector rod rotates and drives the die casting to rotate at the same time, a buckle on the die casting is separated from a buckle groove in the shaping block and slides out along a vertical groove, and the problem that the die casting with the buckle is difficult to eject out through traditional secondary ejection is solved.

Description

technical field [0001] The invention relates to the technical field of die casting moulds, in particular to a secondary ejection die casting mould. Background technique [0002] Due to the special shape of the product in the mold, after one ejection during production, the finished product is still in the mold cavity, and another ejection action needs to be added, which is called secondary ejection. [0003] The Chinese patent discloses a secondary ejection die-casting mold, the patent application number is CN202011529575.4, a secondary ejection die-casting mold, including a fixed module, a movable mold assembly, a first hydraulic cylinder, an installation frame, and a lifting assembly; The first hydraulic rod is driven by the first hydraulic cylinder, the top of the first hydraulic rod is fixed on the support table, the first hydraulic cylinder pushes the core upward, the first hydraulic rod is driven by the first hydraulic cylinder, and the second hydraulic cylinder simulta...

AI Technical Summary

Problems solved by technology

[0004] During mold processing and production, in order to get the finished product out of the mold better, it is often necessary to eject the processed product multiple times. The above-mentioned patent aims at the tight fit between the die-casting product and the mold, and adjusts the height of the ejected part by lifting The length is used to make up for the shortage of the ejection parts, but when encountering some round die-casting parts with buckles inside, it is difficult to make the die-casting parts with buckles fall out of the mold only by pushing up and down multiple times
