Abstract
An injection nozzle has gearing which drives a valve pin to open and close a mold gate, with a venting chamber in a nozzle body allowing vapors to escape before reaching the gearing to avoid fouling of the gearing. The valve pin is actuated by a hydraulic cylinder driving the gearing, which includes a pair of pinion gears driving gear teeth on either side of the upper end of the valve pin. An adjustable stop is provided limiting piston travel in either direction, allowing adjustment of both the closed and open positions of the valve pin.
