Abstract
A melt delivery body is disclosed for an injection molding apparatus. The melt delivery body includes a manifold, housed in a manifold plate, having a melt network with an inlet for receiving melt from a machine nozzle and an outlet substantially axially aligned with the inlet. The melt delivery body further including an in-line valve gated nozzle having a nozzle melt channel, a valve pin in the nozzle melt channel, and a valve pin actuator coupled to the valve pin and positioned substantially axially aligned with the in-line valve gated nozzle and between the manifold and the in-line valve gated nozzle for controlling the movement of the valve pin within the nozzle melt channel. The melt delivery body further including a biasing member for biasing the in-line valve gated nozzle towards the manifold.
