An injection molding machine, comprising a plurality of cavities formed in a die device, resin flow passages for filling a resin in the cavities, selection means disposed in the resin flow passages corresponding to the cavities and selectively opening and closing the resin flow passages, and a control device controlling the selection means. Since valve gates disposed in the die device or die supporting devices are controlled by the control device, the resin can be filled according to molding conditions for each cavity, moldings can be molded in optimum molding conditions without variations in molding accuracy and quality, and the die device can be manufactured at low cost.
