At first, this design acquires us to use Pro/E for the threedimensional modeling of the plastic workpiece. The next task is the injection simulation analysis of the workpiece by using Moldflow. Then we can determine every details of this design one after another. The mold cavity using a mold of two layouts of parts for MPI flow analysis for the spot side gate after the gate to determine the form of integrated injection molding capacity, clamping force, the largest injectionmold pressure area and the technical parameters, such as injection molding machine model to determine Horizontal injection molding XSZY125made. The characteristics of the mold are that slipper is in moving mold and cam finger is in setting template, which can ensure the corepulling acplished very well. This graduate design makes me master the professional knowledge more systematically.
