Real-time temperature control system and method for improving casting quality of aluminum alloy component

Abstract

The invention provides a real-time temperature control system and method for improving the casting quality of an aluminum alloy component and belongs to the technical field of casting and manufacturing processes of aluminum alloys. The system comprises a temperature measuring sensor, a flow controller, an electromagnetic valve controller and an electromagnetic valve, wherein the temperature measuring sensor, the flow controller and the electromagnetic valve controller are located in a temperature anomaly region of a mold, and the electromagnetic valve is located in a pipeline of a cooling water pipe; an output end of the temperature measuring sensor is sequentially connected with flow control input ends of the flow controller and the electromagnetic valve, an output end of the electromagnetic valve controller is connected to an opening-closing signal control end of the electromagnetic valve. The method comprises the following steps: analyzing the temperature anomaly region of the mold in a mold design stage, and distributing the cooling water pipe on the temperature anomaly region; recording and analyzing the temperature measuring sensor in a casting pilot production stage, and determining a qualified temperature interval; opening and closing the cooling water pipe by virtue of the electromagnetic valve in a casting volume production stage. By utilizing the system and the method, the production is visualized, the repeated deliberation and testing are avoided, the testing cost is greatly saved, and the yield of products is guaranteed during the volume production.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy casting production technology, and in particular relates to a real-time temperature control system and method capable of improving the manufacturing quality of aluminum alloy parts. Background technique [0002] In recent years, with the development of light weight, high integration and high performance of products, more and more aluminum alloy parts with very complex structures and shapes and high performance requirements have appeared. When these castings are produced by die casting, it brings new challenges to the enterprise. During the casting process, if the local temperature is too high, it will cause poor heat shrinkage; if the temperature is too low, it will easily cause poor casting. Therefore, it is said in the industry that casting is a process of fighting against heat. For example, in the field of automobile manufacturing, the core control device of an automatic transmission is...
