INJECTION MOLDING NOZZLE WITH SELF-SUPPORTING ACTUATING MECHANISM

摘要

An injection molding nozzle having selfsupported valve member actuating mechanism. The elongated valve member extends rearwardly into a cylinder assembly which is mounted on the main body of the nozzle. The rear end of the valve member is connected to a pneumatically actuated piston to reciprocate it between the open and closed position. A wedge clamp removably attaches the cylinder assembly to a connector member which is bolted to the rear end of the main body of the nozzle.
