| Abstract: | The injection molding process of a tooth shape ejection device was studied based on numerical simulation and experiments.Some key points related to the filling simulation of non-thin walled plastic parts were discussed.The effects of various geometric modeling approaches and grid models on the accuracy of injection molding simulation results were analyzed.A CAD modeling method suitable for plastic parts with a sharp change in thickness was obtained;and a 3D grid model is proved to be more suitable to the in... |
