Optimization of High and Low Speed Switching Position of Injection in High Pressure Casting Main Housing of the Gearbox
Based on 9AT transmission housing,filling simulation was carried out for the die-casting process of the main housing and the influence of high and low speed switching positions on the flow and filling of the metal fluid was analyzed.The results reveal that with the low speed of 0.2 m/s,the high speed of 3.5 m/s and the switching position of 560 mm,the filling flow is smooth and the probability of gas-entrapment is the lowest.The optimized process parameters were adopted for the trial production,and products are dense with the satisfied mechanical properties.
