Notes:
In this study, numerical analysis applying the finite element method (FEM) was used toinvestigate the effect of heat flux and temperature on thermal strain of aluminum alloy casting mold.For numerical analysis, analysis model was considered the effect of shrinkage, rapid temperaturevariation on the casting mold and was applied the temperature calibration to reduce the deformationand stress by temperature difference of inside and outside the mold during the cooling process. Indetail, temperature, deformation and stress distributions occurred inside of casting mold predicted bynumerical method and then investigated the correlations between the heat flux and temperaturevariation during the cooling process. As a result, aluminum alloy casting mold is occurreddeformation and stress because of rapid temperature difference in the initial of cooling, but it can bereduced the thermal strain through the heat flux control and temperature calibration. Accordingly, thetechnique of this numerical study will be helped to make the effective and the good quality of castingmold products
