Abstract
Multi-cavity injection molding apparatus having a number of heated nozzles extending from a melt distribution manifold. Each nozzle is aligned with a tapered insert seated in an opening extending through the manifold. Each insert has a melt duct with a smoothly curved bend to connect the melt passage in the melt distribution manifold with the melt bore through the nozzle. Each insert has a flat disc portion abutting against the rear surface of the manifold. Screws extend through this disc portion and the manifold into an outer collar portion of the nozzle to secure the insert and the aligned nozzle directly to the manifold, while allowing the nozzle to be mounted with its electrical terminal having a selected orientation.
