Die casting forming process for semi-solid metal

Abstract

The invention relates to a die casting forming process for semi-solid metal, and belongs to the technical field of die casting. The die casting forming process includes placing aluminum ingots into smelting furnaces, allowing the temperature of molten aluminum to reach 700-720 DEG C, preserving heat of the molten aluminum at the temperature intervals of 700-720 DEG C for two hours, removing scum on the surface of the molten aluminum by the aid of scumming rods, filling the molten aluminum with gas mixtures of chlorine and nitrogen and cooling the molten aluminum until the temperature of the molten aluminum ranges from 600 DEG C to 650 DEG C; stirring the molten aluminum with the temperature ranging from 600 DEG C to 650 DEG C by the aid of stirring machines for the stirring time ranging from 40 minutes to 45 minutes to obtain stirred mixed molten aluminum; placing the stirred mixed molten aluminum in die casting machines to carry out die casting forming. The die casting forming processhas the advantages that the aluminum ingots are smelted to obtain the molten aluminum, the molten aluminum is purified by the aid of scumming and molten aluminum purifying methods and is stirred by the aid of electromagnetic stirring devices to allow the molten aluminum to be in semi-solid states, die casting is carried out on the semi-solid molten aluminum by the aid of the die casting machinesto obtain die castings, the die casting forming process is novel, and operation can be facilitated.

Description

technical field [0001] The invention relates to a semi-solid metal die-casting molding process, which belongs to the technical field of die-casting. Background technique [0002] Die-casting is a kind of pressure-casting part. It uses a pressure-casting mechanical die-casting machine equipped with a casting mold to pour liquid copper, zinc, aluminum or aluminum alloy into the feed port of the die-casting machine, and passes through the die-casting machine. Die casting, casting copper, zinc, aluminum parts or aluminum alloy parts of the shape and size limited by the mold, such parts are usually called die castings. Die-casting parts have different names in different places, such as die-casting parts, pressure castings, die-casting parts, die-casting aluminum, die-casting zinc parts, die-casting copper parts, copper die-casting parts, zinc die-casting parts, aluminum die-casting parts aluminum die-casting parts, aluminum die-casting parts Alloy castings, aluminum alloy die-ca...

Problems solved by technology

[0005] The semi-solid die-casting process is something that has been researched in the die-casting industry. At present, there is no perfect process plan. Since the temperature of semi-solid metal is lower than that of liquid metal, a new type of die-casting process is required. To meet the needs of semi-solid die casting
