摘要：
A mold tool includes one or more movable core members that push against molten material in the mold cavity during the packing stage of the molding process and thereby reduce the amount of time required for the packing stage of the molding process. The movable core member may be movably mounted in a cavity in a mold half, with nitrogen springs biasing the movable core member to generate a force on the molten material in the mold cavity.
