Gearbox shell aluminium alloy die-casting die

Abstract

The invention discloses a gearbox shell aluminium alloy die-casting die which comprises a base, wherein a second transmission mechanism is mounted in the base; a vertical plate is fixedly connected with the upper surface of the base; two connecting rods are fixedly connected with the right end of the vertical plate; a sliding plate is connected with the outer walls of the two connecting rods in asleeving manner; a first transmission mechanism is in threaded connection with the interior of the vertical plate; the outer walls of two die-casting cylinders are fixedly connected with the second transmission mechanism; and the left end of a die unloading mechanism is fixedly connected with the second transmission mechanism. According to the gearbox shell aluminium alloy die-casting die, throughcooperative application of an electric push rod, a connecting seat, a nut, a hydraulic rod and the like, plenty of manpower can be saved during the die unloading process to further improve the practicality of the entire gearbox shell aluminium alloy die-casting die; through cooperative application of a rotary table, a first threaded rod, the sliding plate, a second threaded rod and the like, popularization and application are facilitated; and through cooperative application of an ejection rod, a die-casting cylinder and a base feeding hole, the using demand of the die-casting die of a user isgreatly improved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to an aluminum alloy die-casting mold for a transmission case. Background technique [0002] Die-casting mold is a tool for casting metal parts. It is a tool that completes the die-casting process on a special die-casting die forging machine. It is widely used in the manufacturing process of gearbox housings. However, the existing gearbox housing aluminum alloy Die-casting molds are difficult to demould, resulting in a decline in the practicability of the overall mechanism, and the reduction in demoulding efficiency will lead to a reduction in production efficiency, which is not conducive to popularization and use, and it is difficult to meet the needs of modern industrial production for the use of die-casting molds. Contents of the invention [0003] The object of the present invention is to provide an aluminum alloy die-casting mold for a transmission case to solve the problem of ...
