Injection molding nozzle manifold

In a multi hot tip gate injection molding apparatus having a heated melt distribution manifold with a front surface mounted in a mold, the melt distribution manifold having a melt passage branching therein from a common inlet to a plurality of spaced outlets on the front surface of the melt distribution manifold, the improvement wherein;

• a plurality of single piece nozzle manifolds are closely mounted to extend frontwardly from the front surface of the melt distribution manifold, each of the single piece nozzle manifolds formed by a plurality of spaced nozzle portions extending forwardly from a single rear manifold portion with a rear surface, the rear manifold portion having a rectangular cross-section with the entire rear surface of the rear manifold portion abutting against the front surface of the melt distribution manifold, each nozzle portion having a conical front surface extending to a pointed tip mounted in alignment with an injection gate, each of the single piece nozzle manifolds having a melt channel extending therethrough from an inlet on the rear surface to receive pressurized melt from the melt passage in the melt distribution manifold, the melt channel branching in the rear manifold portion into a plurality of branches, a respective one of the branches extending to an outlet on the conical surface of each of the nozzle portions.
