ABSTRACT:
A mold assembly includes a stack of mold plates having a first plate and a second plate movable towards one another and away from one another in opening and closing directions between open and closed positions. The stack of mold plates includes a third plate disposed between the first and second plates. The mold assembly also includes a plate movement control device having at least one linkage. Each linkage may include a traveling element mounted to the third plate for movement along a predetermined path of motion relative to the third plate, a first arm having a first end pivotally connected to the traveling element and a second arm having a first end pivotally connected to the second plate and a second end pivotally connected to the traveling element. The at least one linkage is arranged so that upon movement of the first and second plates between the closed position and the open position, the third plate moves away from the first plate by a first predetermined distance and moves away from the second plate by a second predetermined distance.
