Abstract
The present invention relates to an improved nozzle-manifold assembly having utility in injection molding machines for making molded plastic articles. The nozzle assembly employs a clamp ring to apply a clamping force to the nozzle housing to cause it to mate with a manifold so as to prevent leakage of molten plastic material between the nozzle housing and the manifold. The clamp ring is mounted to the manifold by a plurality of screws whose tightening creates the desired clamping force and an effective seal between the nozzle housing and the manifold. The nozzle-manifold assembly also includes a centering ring for positioning the nozzle housing within a bore in a mold plate.
