Top mold of injection molding machine

Abstract

A top mold of an injection molding machine is disclosed. The top mold of this invention has a cylinder housing having a pouring gate, a manifold housing having a manifold and mounted on the lower surface of the cylinder housing, and a nozzle housing having an injection nozzle and mounted on the lower surface of the manifold housing. The top mold also has a heating wire guide hole formed on the lower surface of the nozzle housing. A heating wire extends from an external power source to the injection nozzle through the heating wire guide hole. A clip holding slit is formed on the sidewall of the heating wire guide hole. A clip is held in the clip holding slit and supports the heating wire at a desired place within the heating wire guide hole. The top mold of this invention allows a user to easily and simply repair or replace a heating wire within a short period of time without entirely disassembling the top mold. This top mold is thus reduced in its maintenance cost, and reduces the time the injection molding process is stopped while repairing or replacing the heating wire.
