Aluminum pressing casting

Abstract

The invention discloses an aluminum pressing casting in the technical field of aluminum pressing castings. The aluminum pressing casting comprises four supporting legs, the tops of the four supportinglegs are jointly and fixedly connected with a supporting plate, the left side and the right side of the top of the supporting plate are both fixedly connected with guide rods, and the tops of the twoguide rods are jointly and fixedly connected with a rectangular fixing plate. According to the aluminum pressing casting, a first forming plate and a second forming plate extrude to form a die cavitywhen an upper die descends, the upper die is lifted for die opening after an aluminum pressing casting is formed in a die-casting mode, the first forming plate and the second forming plate are automatically opened, when a lifting mounting plate drives a rack to ascend, a gear is driven to slowly rotate reversely, a first spring extrudes an ejection sliding plate to enable the ejection sliding plate to slowly and stably slide out upwards along the inner wall of a lower die, an aluminum casting is ejected out, the surface of the aluminum casting is not shielded, thus people do not need to stretch into a die-casting cavity for a long time to take the casting, and the possibility of damage caused by taking inconvenience is reduced; and the top of the ejection sliding plate completely bears the aluminum casting, when the aluminum casting is ejected out, the aluminum casting cannot be damaged.

Description

technical field [0001] The invention relates to the field of aluminum die castings, in particular to a die aluminum casting. 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. [0003] The invention patent application number is CN201721902734.4, an aluminum casting die-casting mold, including a left mold base, a left mold, a right mold, a right mold base and a driving device, and the side walls of the left mold base and the right mold base are provided with open...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a die-casting aluminum casting to solve the above-mentioned background technology. After the existing die-casting aluminum die-casting is formed, most of the molded aluminum castings are manually taken out from the mold cavity, which takes a long time. It is easy to cause injury to personnel during the die-casting process, and due to the low hardness of aluminum castings, the ejection mechanisms of existing castings are mostly rod-shaped, and the force-bearing area at the end is small, which is easy to cause damage to aluminum castings and affect the quality of aluminum castings
