Thermal Stress Analysis of the Die during High Pressure Casting

Abstract:

The distribution of temperatures and stresses in the die during high pressure die casting are computed through commercially finite element software developed by Wincast team, Germany. The deformation of the die during its continual running is predicted under the conditions without and with air cooling. The simulated results show that the regions of die, which contact with the casting, is subjected to compressed stresses and the other regions of the die subjected to tensile stresses. Compressed stresses are changed steeply from tensile to compress on the boundary between the casting and the inner cavity walls, which will results in hot-fatigue in those regions of the die. Setting cooling channel within the die is an efficient measure for eliminating hot-fatigue and prolonging life of the die.
