PROBLEM TO BE SOLVED: To prevent the solidification of a molten resin on the opening surface of the discharge port of a nozzle, a die or a T-die in resin molding equipment. SOLUTION: In the resin molding equipment constituted so that the molten resin is discharged on a mold from an injection device through the nozzle, the die or the T-die and mold clamping is subsequently performed to mold a resin product, an infrared heater 4 for keeping the temperature of the molten resin of the opening surface of the discharge port 2 of the nozzle, the die or the T-die or heating the molten resin is obliquely arranged in front of the discharge port 2 toward the discharge port 2. Further, a shutter 8 for closing the discharge port 2 in place of the keeping of the temperature of the molten resin of the opening surface of the discharge port 2 or the heating of the molten resin using the infrared heater and may be heated by a heater 9.
