| description | An injection molding apparatus includes an injection manifold (44) having an inlet and a melt channel. The manifold melt channel branches to a plurality of melt channel outlets (17). A hot runner injection nozzle (10) includes an axial melt channel (58) extending along a central axis (71) and communicating with one of the manifold melt channel outlets (17). The nozzle further includes at least two angled melt channels (204) disposed at an angle to the central axis. At least two nozzle tips (206) are provided, and each includes a nozzle tip melt channel (210) in communication with one of the angled melt channels. A valve pin (100) is disposed at least partially within the axial melt channel coaxially with the central axis and movable within the axial melt channel. Lateral valve pins (104) movable within the nozzle tip melt channels are disposed at an angle to the valve pin. Linkage elements (130) continuously connect the lateral valve pins to the valve pin. Axial movement of the valve pin is transmitted through the linkage elements to the lateral valve pins to open and close communication between the nozzle tip melt channels and the lateral mold gates. |
