Abstract
A nozzle assembly for use with injection molding apparatus includes an outer sleeve having a relatively large bore extending from an open rearward end forwardly to a substantially closed forward end, and having an injection orifice therein. An inner nozzle tip is located within the sleeve, and has a radial flange and an internal extending from a rearward open end to a forward tip having a plurality of flow orifices upstream of the injection orifice. A manifold insert is located within the outer sleeve and includes a through bore in axial alignment with the bore of the nozzle tip. The manifold insert has a forward end which receives the nozzle tip and which abuts the radial flange. A coil heater is located radially between the manifold and the outer sleeve, a forward end of the coil heater seated on the radial flange. The manifold insert, nozzle tip and coil heater form a subassembly which is easily removed and reinserted vis-a-vis the outer sleeve.
