1. IntroductionThe injection molding process is generally divided into the following steps: mold clamping → injection holding pressure → melt rubber feeding → cooling setting → mold opening thimble. The completion of each action has a precise fit of several parameters such as time, pressure, speed, position, etc., that is, the displacement at a certain position has a corresponding pressure and speed, and the pressure and the pressure in different positions and times The speed is variable. At the same time, after each action is completed, a termination signal is sent to the program control...
