Adjustable die-casting machine for extrusion forging and using method thereof

Abstract

The invention relates to an adjustable die-casting machine for extrusion forging and a using method thereof, and belongs to the technical field of die-casting machines. The die-casting machine comprises a support table and a feeding device, wherein the feeding device is arranged above the support table; a support is further arranged on the support table, and the support is located at one side of the feeding device; an injection gun is mounted at the top end of the support through a fixing seat, and the injection gun is connected with a discharge hole of the feeding device through a feeding pipe; an injection valve is mounted at one side, close to the discharge hole of the feeding device, of the feeding pipe; a die-casting die is arranged below the injection gun; and a cooling bin is arranged below the die-casting die, and the cooling bin is mounted above the support table through an oscillation device. According to the die-casting machine, molten metal is stirred, the full fluidity of the molten metal is kept, the temperature of the molten metal is controlled and adjusted through a heating resistance wire, and secondary cooling is carried out on a casting after die opening, so that the situation that workers are burnt due to the fact that the temperature of the casting is too high is avoided.

Description

technical field [0001] The invention belongs to the technical field of die-casting machines, and relates to an adjustable die-casting machine for extrusion forging and a use method thereof. Background technique [0002] Die casting, referred to as die casting, is a relatively fast-growing method for manufacturing metal products without cutting. High pressure and high speed are important features that distinguish die casting from other casting methods. Die casting machine is a machine used for pressure casting. Under the action of pressure, the molten metal is hydraulically injected into the mold for cooling and forming. After the mold is opened, solid metal castings can be obtained. Most of the die casting castings do not contain iron, such as zinc, copper, Aluminum, magnesium, lead, tin and their alloys. Die-casting was originally used to die-cast lead characters. With the advancement of science and technology and industrial production, especially with the development of i...

AI Technical Summary

Problems solved by technology

[0003] 1. Since different metal castings require different temperatures during die-casting, the molten metal needs to reach a specified temperature during die-casting. At present, the feeding device of most die-casting machines does not heat the molten metal at a constant temperature, making the temperature of the molten metal unstable. , there are more defective products casted

[0004] 2. When feeding, the fluidity of the molten metal is not enough, so that the molten metal settles in the feeding channel, which not only causes a lot of waste of raw materials, but also is very inconvenient when cleaning the feeding channel

[0005] 3. The metal liquid needs to be injected at high pressure, which causes the injection head to wear out quickly and needs to be replaced in time. The installation and disassembly of the current injection machine and the injection gun are not flexible enough

[0006] 4. The casting after mold opening has not undergone secondary cooling, resulting in the temperature of the casting is still too high, and workers are prone to burns when storing the casting
