Claim:
A hot runner nozzle assembly for an injection mold comprising: a. an elongated nozzle core having a longitudinal axis and opposite first and second ends and a nozzle core melt channel extending along the longitudinal axis, b. a nozzle tip mounted to the first end of the nozzle core, the nozzle tip having a nozzle tip melt channel, the nozzle tip being coaxially aligned with the nozzle core such that the nozzle tip melt channel and the nozzle core melt channels are aligned, the nozzle tip having a gate, c. the nozzle core having a flange portion formed on the second end, the flange portion having a bulge extending from the axis of the nozzle core, d. a nozzle housing mounted to a hot runner manifold, the nozzle housing having an opening dimensioned and configured to receive the flange portion of the nozzle core, the nozzle housing having a shoulder portion and a slot, the slot being dimensioned to permit the bulge of the flange portion to pass through the slot when the bulge and the slot are aligned, the flange portion and the nozzle housing being dimensioned and configured to permit the flange to rotate in the housing between a first position wherein the bulge of the flange is aligned with the slot of the housing to permit the nozzle core to be inserted and removed from the housing and a second position wherein the bulge of the nozzle core abuts the shoulder of the housing thereby preventing the nozzle core from being removed from the nozzle housing, and e. a locking member for releasably locking the flange in its second position.
