In a glass product forming machine having moldsA andB each composed of a pair of split moldsand, and a mold cooling device X for cooling the moldsA andB to control the temperatures thereof, in order to prevent the occurrence of a defect such as deformation or cracks in a formed article due to a temperature difference between the split moldsand, the mold cooling device X is configured to include: cooling mechanismsR andL provided to the respective split molds, the cooling mechanisms each individually applying cooling air to each of the split moldsandof the moldsA andB; valve mechanismsR andL for individually opening and closing each of paths for introducing cooling air to the respective cooling mechanismsR andL; temperature detection means for detecting the temperature of at least one of the split molds; and a temperature control devicefor generating and outputting control signals for controlling the opening and closing operations of the respective valve mechanismsR andL on the basis of the detected temperature value by the temperature detection means.
