1. An injection molding apparatus comprising:
- a manifold having at least one manifold melt channel for receiving a melt stream of moldable material under pressure;
a first nozzle having a first nozzle melt channel in fluid communication with said manifold melt channel;
a second nozzle having a second nozzle body, a second nozzle melt channel in fluid communication with said first nozzle melt channel and a plurality of outwardly extending melt passages in fluid communication with said second nozzle melt channel, said nozzle body having a length measured along a longitudinal axis of the second nozzle, a width and a depth;
a nozzle link provided between the first nozzle and the second nozzle and having a nozzle link melt passage for fluidly coupling the first nozzle melt channel and the second nozzle melt channel, the nozzle link being threadably attached to the first nozzle and slidable within an aperture of the second nozzle; and
a plurality of gate seals coupled to said second nozzle, said plurality of gate seals for delivering the melt stream from said plurality of outwardly extending melt passages to a plurality of mold cavities through respective mold gates, wherein the length of said second nozzle body is less than at least one of said width and said depth of said second nozzle body.

Abstract
An injection molding apparatus includes a first, rear-mounted nozzle that is coupled to a manifold for receiving a melt stream therefrom. A second, front-mounted nozzle is coupled to the first nozzle by a nozzle link that is provided between the first and second nozzles. A plurality of gate seals are coupled to a forward end of the second nozzle. The gate seals receive melt from a plurality of melt passages and deliver the melt to a plurality of mold cavities through respective gates. The second nozzle is slidably removable from the first nozzle via the nozzle link to facilitate repair or replacement of the gate seals.
