Abstract: A multi-station rubber injection molding machine including plural molding stations for respective molds, a rubber injection unit, and a manifold assembly for selectively transferring uncured rubber from the rubber injection unit to a mold in any one of the molding stations. The manifold assembly includes an inlet for receiving molding material from the injection unit and a plurality of nozzle members each including a transfer passage and being movable into and out of operative engagement with a mold in the respective molding station. Each nozzle member has associated therewith members for connecting and disconnecting the transfer passage therein to and from the inlet respectively in response to movement of the nozzle member into and out of operative engagement with the mold.
