Numerical Simulation and Process Optimization of Die Casting for Aluminum Alloy Engine End Caps
The numerical simulation of die casting mold filling and solidification process of the rear end cover of an alu-minum alloy engine was carried out,and the possible shrinkage cavity and porosity were predicted.The filling and solidification were analyzed,and the cooling channel was optimized.The optimal process parameters were determined by orthogonal test:pouring temperature of 680℃,injection velocity of 4 m/s,preheating temperature of 220℃.The optimized scheme was used for die casting production and inspection.The test results reveal that the quality of die cast-ing is significantly improved.
