An injection molding apparatus includes an injection manifold having a melt channel. A hot runner injection nozzle includes an axial melt channel extending along a central axis and communicating with the manifold melt channel. The nozzle further includes at least two angled melt channels disposed at an angle to the central axis. At least two nozzle tips are provided, and each includes a nozzle tip melt channel in communication with one of the angled melt channels. An axial valve pin is disposed coaxially with the central axis and is disposed outside of the axial melt channel. Lateral valve pins movable within the nozzle tip melt channels are disposed at an angle to the valve pin. A linkage system connects the lateral valve pins to the axial valve pin. Movement of the axial valve pin is transmitted through the linkage system to the lateral valve pins to open and close communication between the nozzle tip melt channels and the lateral mold gates.
