Hot tip insulator retainer

摘要

An injection molding nozzle tip thermal insulator includes an apparatus for removably fastening the insulator to a nozzle tip having a receiving detent therein. The apparatus includes a fastening structure that engages the nozzle tip receiving detent and holds the insulator onto the nozzle tip. The fastening structure is movable between a first position where the insulator is fastened to the nozzle tip, and a second position where the insulator is removable from the nozzle tip. Also included are a method of removably attaching the insulator to the nozzle tip, and assembly and removal tools for attaching and removing the insulator from the nozzle tip, respectively.
