A mold for use in a gas-assisted injection molding system having a nozzle includes a runner shut-off subsystem which prevents pressurized gas from flowing through the runnerand into the nozzle. A pair of pins are preferably mounted on a plate to move therewith between extended and retracted positions of the plate. The pins are slidably fit within one mold half of the mold to move within the runner between extended gas-blocking positions to block the flow of pressurized gas through the runner and into the nozzle and retracted positions to allow the flow o...
[ What is claimed is:] [1.] A mold for use in a gas-assisted injection molding system including a nozzle for injecting molten plastic into the mold, the mold comprising:a first mold half;a second mold half, the first and second mold halves being movable relative to each other between an open position and a closed position, wherein the first and second mold halves define an article-defining cavity, a runner, and a gate for flow coupling the runner to the article-defining cavity; anda runner shut-off subsystem including:a plate,a pair of pins mounted on th...
