【Abstract】 In die casting process,the distribution of temperature field of mould board of the die-casting equipment has significant effect on the die-casting quality,the service life of equipment and productivity.According to characteristics of die-casting,on the basis of reasonable simplification of the heat transferring process during die casting,the mathematical model for temperature field of die-casting mould board was established suitable for the numerical simulation and the boundary conditions used to solve temperature field of die-casting molds were determined.The temperature and stress state in different parts of mould board during die casting process were analyzed and the structure of the mould board was optimized,which provided basis for the design and manufacturing of die-casting equipment.更多还原
