Numerical Simulation and Process Optimization of One Mold Multi-cavity Die Casting YL112 Aluminum Alloys Based on ProCAST
Aiming at the demand for uniformity of microstructure performance of YL112 die-casting aluminum alloy one-mold multi-casting products,ProCAST software was used to simulate the typical one-mold multi-casting process,and the two die-casting schemes with different filling sequences were compared.The results show that the uneven temperature field distribution of one-mold multi-cavity die-casting based on sequential solidification of one-mold multi-cavity die casting causes obvious shrinkage and shrinkage hole defects in the near gate end casting,resulting in poor uniformity of casting performance.Subsequently,the same process flow path pouring system is adopted to realize the simultaneous filling and solidification process of a mold multi-cavity casting,which improves the temperature field distribution of the casting and reduces the process defects.After actual production verification,die-casting parts with good microstructure uniformity are obtained.
