Intelligent control method for cooling process and pressurizing process of aluminum wheel mold

Abstract

An intelligent control method for a cooling process and a pressurizing process of an aluminum wheel mold is characterized in that an upper computer system, a die-casting machine PLC system, the aluminum wheel mold and a standard temperature curve for temperature control of the aluminum wheel mold are included, the aluminum wheel mold serves as an installation carrier of a thermocouple, and the upper computer system is responsible for real-time mold temperature analysis, decision making and instruction sending; the die-casting machine PLC system is responsible for completing corresponding adjustment according to the instruction sent by the upper computer system. By means of the method, the pressurization process can be automatically adjusted according to the actually-measured temperature change of the aluminum wheel mold, and stable mold filling and timely pressurization and pressure relief are implemented; and meanwhile, the cooling process of the die can be automatically adjusted according to the actually measured temperature change of the aluminum wheel die, so that the temperature of the die fluctuates in a stable interval, and the production process is stable.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to an intelligent control method for a cooling process and a pressurizing process of an aluminum wheel mold. Background technique [0002] At present, intelligent casting and digital casting are more and more valued by the industry, and many companies have begun to invest in research and development in this area. The current situation is that no matter the cooling process or the pressurization process, it only depends on time control, such as Figure 10 As shown in the process card, the conditions at the casting site are constantly changing, such as temperature fluctuations of molten aluminum, mold coating peeling, environmental temperature changes, etc., and the time-controlled process cannot make corresponding adjustments in time for such changes, resulting in waste products. , and only when there is a waste product can the on-site personnel perceive the change of the on-site cond...

Problems solved by technology

The current situation is that both the cooling process and the pressurization process only rely on time control, such as Figure 10 As shown in the process card, the conditions of the casting site are constantly changing, such as the temperature fluctuation of the aluminum liquid, the peeling off of the mold coating, and the change of the ambient temperature. , and only when there are waste products, can the on-site personnel detect the changes in the site conditions and intervene in the adjustment

The key to the intelligentization of aluminum wheel low-pressure casting lies in how to realize the intelligent adjustment of the cooling process and pressurization process in the casting process. The purpose of realizing the intelligent adjustment of the cooling process is to always keep the mold temperature in a stable range. Once the stable production state changes, it will intervene in the adjustment, so that Ensure stable product quality and avoid unnecessary waste products; realize intelligent adjustment of pressurization process The purpose is to adjust the conversion of filling, pressurization and pressure relief in real time, thereby improving production efficiency, and it is impossible to realize intelligent casting with intelligent control of cooling process and pressurization process All are incomplete intelligent manufacturing
