Abstract
An injection molding apparatus includes a plurality of valve-gated nozzles, each nozzle having a respective valve pin that is actuated by an actuator. A nozzle tip component for taking one of the valve-gated nozzles of the injection molding apparatus out-of service, wherein the nozzle tip component has a surface that grips the respective valve pin to lock the valve pin in an out-of-service position thereby preventing flow of molding material into an associated mold cavity and causing disengagement of the valve pin from the actuator.
