<p>Injection molding apparatus having several side gate seals (24) extending radially from a heated nozzle (10). The nozzle has a locating flange portion (76) which is received in an opening (12) in the mold. This laterally locates the nozzle (10) while allowing it to be advanced for mounting of the side gate seals (24) and then retracted to an assembled position where it is longitudinally located by the side gate seals (24) being received in the mold. Thus, the nozzle (10) is longitudinally located in the same plane (124) as the gates (18) and in one embodiment a melt distribution manifold (44) is free to float with the rear ends (46) of the nozzles. This also provides for differences in the thermal expansion due to possible different operating temperatures. <IMAGE></p> |
