Front-mountable injection molding nozzle

摘要

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.
