Patent ID: 7658605

Claim:
An injection molding apparatus comprising: an injection manifold having an inlet and a melt channel; a hot runner injection nozzle having an axial melt channel extending along a central axis and communicating with said melt channel, the hot runner injection nozzle also including an angled melt channel disposed at an angle with respect to the central axis such that the angled melt channel and the axial melt channel are not parallel to each other; a nozzle tip including a nozzle tip melt channel, wherein said nozzle tip melt channel is in communication with said angled melt channel; a primary valve pin disposed coaxially with the central axis and disposed entirely outside of the axial melt channel; a secondary valve pin movable inside the nozzle tip melt channel, wherein the secondary valve pin is disposed at an angle to the primary valve pin such that the secondary valve pin is not parallel to the primary valve pin; a linkage system continuously connecting the secondary valve pin to the primary valve pin; and a lateral mold gate disposed at an angle with respect to the central axis such that the mold gate is not parallel to the central axis, the mold gate communicating with a mold cavity, wherein movement of the primary valve pin is transmitted through the linkage system to the secondary valve pin to open and close communication between the nozzle tip melt channel and the lateral mold gate.
