It is more difficult to find the motion and interference elements produced by the injection molding mold than the obstacle elements, because the motion and interference elements of the injection molding parts are more hidden and difficult. In general, it can be found through the motion analysis diagram or motion modeling of the motion and interference elements of the injection molding part, and the motion analysis diagram or modeling of all parts of the motion mechanism

In addition to the three basic forms of motion in the molding process: mold opening and closing, core pulling and mold ejection, injection molding manufacturers also have different forms of motion according to the selection of motion actuators in the molding process. It can be seen that the motion form of the injection mold depends on the motion form required for injection molding, the coordination of motion organization and the form of the selected motion actuator. Only when the injection mold can complete all the required customized movements can the analysis, core pulling and mold ejection of the injection parts be achieved. At the same time, the rhythm of various sports organizations should coordinate with each other, otherwise there will be sports interference
