ABSTRACT:
A valve gate assembly is provided for regulating a flow of molten material through a gate and into a mold. The valve gate assembly includes a movable valve having a closed position closing the gate to prevent molten material from entering the mold and an opened position opening the gate to allow molten material to enter the mold. The valve gate assembly further includes a biasing assembly operatively cooperating with the valve and providing a force to urge the valve in the closed position. The valve has a shoulder for cooperating with the molten material to create backpressure to move the valve against the force to the open position.
