Abstract:  By using Visual C++, a model with post-processing was carried out to simulate the temperature and strength distributions of the mold(core). The results are shown in 256-color graphic mode. With this model, the temperature and strength distributions of the mold(core) both in case of heating process for core inthe furnace and solidification process for a thin-wall aluminum alloy casting in the mold(core) are numerically simulated. The results show that the temperature and strength distributions of the mold(core) were uneven because the thermal conductivity of the resin sand was much small. This study laid a basis for the optimum design of the mold(core) properties.
