1. An injection molding system comprising:
an injection nozzle configured to inject, via an injection cylinder, resin into a mold;
a conveying device configured to convey the injection nozzle between a first position where the injection nozzle injects resin into a first mold and a second position where the injection nozzle injects resin into a second mold, and
a controller configured to switch an operational mode of the injection molding system between a first mode where initiating rotation of a screw of the injection cylinder occurs after the injection nozzle is moved from one of the first position and the second position to the other of the first position and the second position and a second mode where initiating forward rotation of the screw of the injection cylinder occurs while the conveying device conveys the injection nozzle.
