Abstract
A runner for supplying resin to a cavity includes a sprue that is supplied resin from a nozzle of an injection molding machine, a first path formed in the runner, where the resin flows in the first path from the nozzle when the nozzle connects to the sprue, a first pin that moves to a first position to increase the size of the first path before the resin is supplied to the first path and moves to a second position to decrease the size of the first path before the nozzle separates from the sprue.
