Numerical simulation of low pressure die-casting aluminum wheel
The FDM numerical simulation software, View-Cast system, was employed to simulate the low pressure die casting (LPDC) process of an aluminum wheel. By analyzing the mold-filling and solidification stage of the LPDC process, the distribution of liquid fraction, temperature field and solidification pattern of castings were studied. The potential shrinkage defects were predicted occur at the rim/spoke junctions which is in consistence with the X-ray detection result. The formation mechanism, as well as the distribution rule of the defects, has also been studied。A solution towards eliminating such defects has been presented. The cooling capacity of the mold is improved by installing water pipes both in the side mold and top mold. The analysis of the occurrence of shrinkage defects under forced cooling mode has proved that the cooling system in the mold is an effective method for the reduction of the volume of shrinkage defects.
