Simulation and analysis of flow in the injection chamber of die casting machine during the slow shot phase

摘要

A three-dimensional numerical model, developed on the basis of the finite difference method and the volume fluid method, is used to analyze the mechanism of the liquid metal flow and the possibility of air entrapment in the injection chamber of die casting machine during the slow shot stage. The model gives designers a clear overall picture of the slow shot process and enables them to optimize the injection parameters.
