A liquid forming device for light alloy

Abstract

The invention relates to a liquid forming device for light alloy, which is designed for the circumstance that the defects such as dispersed shrinkage, shrinkage cavity, pores and inclusions are easily caused because the temperature of a mould is not easy to control when the liquid forming of the light alloy is performed, and the deviation between the actual temperature of the mould and the pre-set temperature of the mould is relatively large during pouring. A heating oil way is arranged in the mould, circulation heat transfer oil is used to guarantee the stability of the temperature of the mould, a thermocouple is used to monitor the temperature change of the mould, and a push-pull rod motor is adopted to realize the process of opening and closing the mould, so that the labour intensity is alleviated, and the production efficiency is improved; a liquid forming manner that a bent runner, a horizontal runner and a vertical runner are combined is used, so that the defects such as dispersed shrinkage, shrinkage cavity, pores and inclusions are eliminated, and the quality of light alloy castings is improved; and the device is easily is advanced in design, compact in structure, and convenient to mount and use, and is an advanced liquid forming device for the light alloy.

Description

technical field [0001] The invention relates to a light alloy liquid forming device, which belongs to the technical field of light alloy liquid casting. Background technique [0002] Light alloys include magnesium alloys, aluminum alloys, titanium alloys and other light metal alloys, which are widely used in automobiles, ships, aerospace, electronics, defense industries and other fields. [0003] The processing and forming of light alloys mainly include liquid forming, welding forming, forging forming, machining forming, etc.; light alloy liquid forming is to inject liquid metal into sand mold or metal mold, open the mold after cooling, take out the casting, and then carry out the casting process. Mechanical processing to make parts and components; the conventional metal mold liquid casting molding method is to preheat the mold before pouring, stop heating when it reaches the predetermined temperature and pour, and stop heating until the molten metal is poured into the mold....

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to design a light alloy liquid forming device for the deficiency and backwardness of the background technology. The mold is designed as a fixed mold and a movable mold, and an oil circuit is arranged inside the mold, and the temperature of the mold is guaranteed to be stable by using a circulating heat transfer oil circuit. The thermocouple is used to monitor the temperature change of the mold, and the push-pull rod motor is used to realize the mold opening and closing process; the liquid casting method combining curved runners, horizontal runners and vertical runners is used to eliminate shrinkage porosity, shrinkage cavities, air holes and inclusion defects , to improve the quality of light alloy castings
