Numerical Simulation and Process Optimization of Low-pressure Die Casting for Aluminum Alloy Cylinder Blocks
To enhance the forming quality of low-pressure casting ZL114A aluminum alloy cylinder blocks, the filling and solidification processes were numerically simulated using ProCAST software to investigate the temperature field distribution, solid fraction variation, and formation of shrinkage porosities and cavities. Relying on simulation results, the tendency of mechanical property degradation in the bearing seat area was predicted and validated. After optimizing the gating system and adjusting process parameters, defect formation was effectively suppressed, and the mechanical performance of the bearing seat region was significantly improved. The solidification rate of optimized casting is increased by 9.37%, while shrinkage defects are reduced by 71.5%. Practical production confirms excellent forming quality and superior mechanical properties in critical areas, where tensile strength reaches 312 MPa, exceeding the standard requirement. The results indicate the feasibility of optimized scheme, providing valuable reference for production of similar complex structural castings.
