hankingmould on 08 May 20The mold opening process: the three-plate mold has two parting processes, the first between the stripping plate and the cavity plate, and the second time between the cavity plate and the core plate. When the core side is pulled by the injection molding machine, as the A and B plate are equipped with a latch lock, and there is no connection or obstruction between the stripping plate and the A plate (in most cases, the pull rod is also equipped with a spring) At this time, the stripping plate is first separated from the cavity plate by the pulling force, and the cavity plate moves backward with the core plate. When moving to the set distance, it is blocked by the pull rod limiting block, because the A plate continues to move with the injection molding machine. Therefore, the pull rod is also driven, and the pull rod drives the stripping plate to move to the next set distance and then the pull rod and the cavity plate stops moving.
