Magnesium alloy semi-solid production method

Abstract

The invention relates to the technical field of cold die casting, and in particular relates to a magnesium alloy semi-solid production method. In order to mainly solve the problem that an existing semi-solid magnesium alloy forming machine can only produce small-size and thin-wall products due to limitation of an injection and pulping integrated material pipe and a heating system, the following technical scheme is provided that the semi-solid magnesium alloy forming machine comprises a production system, the production system comprises an injection system and a soup injection system, a servo motor is installed on the soup injection system, and oil cylinders are arranged on the two sides of the servo motor. The casting prepared through the method is compact in structure, defects such as casting or forging are reduced, the comprehensive mechanical property is greatly improved, the heating power and the feeding metering are increased, the large product requirements of automobile production parts and products in the communication field are met, magnesium alloy does not make contact with air, and the formed and melted magnesium alloy does not make contact with the air in a closed container. Therefore, the risks of spontaneous combustion and explosion are avoided, the casting production efficiency is high, and the cost is reduced through comprehensive utilization of the magnesium alloy.

Description

technical field [0001] The invention relates to the technical field of cold die casting, in particular to a semi-solid production method of magnesium alloy. Background technique [0002] Magnesium alloy semi-solid slurry is used in the production process of cold die-casting machines, which can also meet the performance requirements of semi-solid special equipment; at present, semi-solid magnesium alloy products are mainly produced by injection molding integrated machines with molds, due to injection force defects cannot It is cast into a large-scale high-strength product, and there are many uncontrollable factors in the application of the machine that cause the material pipe flange interface to leak or even be scrapped. After the injection is completed, the cooling time of the cavity product must wait until the pulping device is allowed to fall back. Stock preparation, which causes the whole cycle takt time to be lengthened. Currently, there is only one Japanese company in ...
