Description

Technical Field

[0001] This utility model relates to the field of die-casting equipment technology, specifically a die-casting equipment for aluminum alloy parts. Background Technology

[0002] Aluminum alloy fittings refer to various parts made of aluminum alloy materials. They have properties such as light weight, high strength, corrosion resistance, and easy processing. Aluminum alloy fittings come in a wide variety of types and are widely used in many fields such as construction, aerospace, and transportation.

[0003] Die casting is one of the processes in the processing of aluminum alloy parts. Molten aluminum alloy is rapidly injected into a mold under high pressure, and after cooling and solidification, it forms the aluminum alloy parts of the required shape. This process requires the use of a die casting device. During the die casting operation, the parts formed by hydraulic molding of aluminum alloy have a very high temperature, so when the parts are removed, it is necessary to wait for them to cool down. The traditional air cooling method is slow, which reduces work efficiency. Therefore, a die casting device for aluminum alloy parts is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a die-casting device for aluminum alloy parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a die-casting device for aluminum alloy parts, comprising a worktable and an electric cylinder. A fixed seat is fixedly connected to the upper surface of the worktable, and a receiving cavity is formed on the upper surface of the fixed seat. A mounting frame is fixedly connected to the upper surface of the fixed seat, and a fixed mold base is fixedly connected to the inner side wall of the mounting frame. A lifting plate is fixedly connected to one end of the piston rod of the electric cylinder, and a moving mold base is mounted on the lower surface of the lifting plate. An injection pipe is provided on the front surface of the moving mold base. A cold water tank is provided on the left side wall of the worktable, and a water outlet pipe connects the upper surface of the cold water tank to the bottom of the left side wall of the fixed seat. The upper surface of the worktable is located on the left side... A pump body is installed, with an inlet pipe connecting the pump body's inlet end to the top of the left side wall of the fixed base, and a pumping pipe connecting the pump body's outlet end to the upper surface of the cold water tank.

[0010] As a further preferred embodiment of this technical solution: the lower surface of the workbench is uniformly welded with support legs.

[0011] As a further preferred embodiment of this technical solution, a rubber pad is adhered to the bottom of the support leg.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses an electric cylinder to drive a lifting plate and a moving mold base downwards, causing the moving mold base and the fixed mold base to close. Molten aluminum alloy is then injected under high pressure into the mold cavity through the injection pipe to achieve die casting. A pump draws cold water from the cold water tank and delivers it to the receiving cavity. The cold water contacts the fixed mold base for heat exchange, cooling the fixed mold base and the components within it. A motor drives the connecting shaft, driving bevel gear, driven bevel gear, rotating column, and propeller to rotate, agitating the cold water and promoting its flow. This enhances the cooling effect, accelerates the cooling speed, and improves the efficiency of the aluminum alloy component die casting process. Attached Figure Description
