Abstract: A position detector to detect the fully open position of a valve gate pin in a gate valve controlling the flow of molten plastic material to a die cavity includes a sensing member which has a DC voltage impressed thereon and which is electrically isolated from the valve gate assembly. An extension of the valve gate pin contacts the sensing member when the valve gate pin is in its fully open position to short the impressed voltage and thereby indicate a fully open condition.

Abstract: In order to facilitate the formation of a plastic member with an aperture in a central portion thereof, a ring gating valve arrangement is provided with a multi-piston servo arrangement which enables a specially configured pin to be stepwisely reciprocated back and forth within a molding device. The pin is formed with a land at one end which is dimensioned and shaped to produce the required aperture. The pin further features a channel structure which includes an annular recess adapted to permit plastic to flow into the center of the mold cavity area when the pin is thrust to a predetermined location. After the cavity is filled with hot plastic, the pin is retracted to a position wherein the annular recess is located within a removable gate bushing and the shaped land is pulled up until it is appropriately located in the mold cavity area. As the injected plastic cools and solidifies, the shaped land acts as the aperture molding pin and forms a clean aperture in the molded part. After solidification, the pin is retracted and the mold is opened to permit the molded part to be ejected.
