ABSTRACT:
The nozzle manifold assembly of an injection molding machine is infinitely adjustable horizontally perpendicular to the nozzle axis. The nozzles themselves project through slots in the front clamp plate of the machine which give flexibility to the mold designer in his placement of sprues and runners for filling the mold. Additionally this manifold assembly and its associated injection hardware, such as the shot accumulator, hydraulic pressure accumulator and valving, are mounted on a carriage assembly which is capable of moving horizontally in a direction parallel to the axis of the nozzles thereby allowing the nozzles and associated heater bands to be accessed and maintained without the need for removing the mold from the machine.
