A gas discharging system of a multifunctional molding machine is provided to discharge the gas generated in a molding machine cylinder to the outside efficiently by using an exhaust gas discharging unit. A gas discharging system of a multifunctional molding machine comprises a gas discharging and fuel supply unit, an exhaust gas discharging unit(200), and a control unit(250). The gas discharging and fuel supply unit is formed with dual outer pipes to form fuel injection pipes and exhaust gas discharging collecting spaces. The exhaust gas discharging unit has an electronic opening and closing valve configured at an air suction port(130) to discharge the exhaust gas to an air discharging port forcibly. The control unit controls the opening and closing time of the valve and changes the pressure of the exhaust gas discharging unit.
