【Abstract】 This study analyzes the heat transfer during the filling/postfilling and cooling stages of an injection molding. In the simulation,heat exchange between melt and mold interface is treated as transient. Asymmetric temperatur e boundary condition is employed to treat non isothermal, non-Newtonian fluid flow. Non-uniform melt temperature is treated as initial conditions for cooling analysis. On the basis of the same triangle meth, an integrated simulation is realized by coupling interactively so as to match the temperature and heat flux at the mold-melt interface.更多还原
