Quality Control Study on High Pressure Casting Based on Magma and Ultra-red Simulation

Abstract

The temperature control of high-pressure die casting mold is one difficult problem in die industry. The inner quality of product is greatly affected by mold temperature. Taking the automobile gearbox parts as an example, by the combination of waterproof thermocouple and TP700-16/TP700-40 multi-channel temperature tester, one set of device for monitoring mold real-time temperature is developed. The high pressure casting die and mold temperature field simulation are carried out by using Magma software. By simulating analysis and reducing process parameter interval of Magma, the ideal mold temperature is obtained and the quality problem of die casting is solved after the simulation parameters are copied to the die casting machine. The practical results show that the instability of die casting is decreased, the time cost of die casting is decreased by increasing die casting Overall Equipment Effectiveness (OEE), the risk of personal accident is reduced and the product scrap rate can be effectively reduced. Finally, the future research directions are pointed out.
