A systematic numerical simulation is conducted for the right?angled ABS plastic elbow pipe by dint of moldflow, which has not only accomplished the gating system design of plastic elbow pipe, but also weakened the influence of welding marks. Meanwhile, the influence of cooling system design on product's temperature distribu?tion has been predicted to optimize the cooling solution. Additionally, the warp analysis is implemented to deter?mine that the uneven contraction is the major factor to product size, shape and precision, based on which product molding process and features are figured out. Finally, based on the numerical simulation analysis results, the in?jection mold of plastic elbow pipe is designed to optimize injection mold structure. The practice proves that this method plays a guiding role in the design of injection mold.
