Abstract

An injection molding nozzle comprises a material feed pipe subtending a flow duct communicating flow-wise with at least one nozzle tip. Each tip points transversely to axial direction A of the nozzle and is held by a manifold. The manifold is pluggable/insertable into the material feed pipe and includes a neck and a base. A manifold duct system is subtended in the manifold. A main duct extending the flow duct is in the neck and the base comprises a deflection site and at least one manifold duct. The manifold duct runs radially to axial direction A. The nozzle tip is affixed in a seating unit fitted with a central recess. Radial boreholes running transversely to axial direction A fit into the seating unit and receive plugged-in nozzle tips. The central recess receives the base, the nozzle tip being secured by the base to and in the seating unit.
