Beschreibung
Zusammenfassung:	PURPOSE: A device for injecting resin and discharging gas from an injection molding machine is provided to reduce a time and costs to manufacture plastic resin products since gas from melted resin is discharged through a gas discharge unit simultaneously with injection of melted resin, so a process to remove gas is skipped. CONSTITUTION: A device for injecting resin and discharging gas from an injection molding machine comprises an injection nozzle(10), a gas discharge pipe(20), and a gas exhaust unit(30). Melted resin passes through a resin hole(11) in the injection nozzle. The gas discharge pipe comprises a gas hole(21). One end of the gas discharge pipe is coupled to at least a part of the injection nozzle. One end of the gas exhaust unit is connected to the other end of the gas exhaust pipe. Melted-resin gas flows into the gas hole and high-pressure gas flows into the other end of the gas exhaust unit from the outside.
