ABSTRACT:
Multi-cavity injection molding apparatus having several side gate seals seated around the front end of each heated nozzle. Actuating mechanism is provided to advance the melt distribution manifold and the attached nozzles to a forward position without removing the mold from the molding machine. In this position, the front ends of the heated nozzles protrude from the mold to facilitate removal of the side gate seals and hot tip torpedoes for cleaning or replacement.
