PROBLEM TO BE SOLVED: To provide a mold temperature controlling machine which is simply structured so that its manufacturing cost is low; highly mass-productive; capable of controlling the temperature of a mold successfully; and therefore, is of an extremely high goods-value. SOLUTION: The mold temperature controlling machine for controlling the temperature of the mold 1 by passing a temperature controlling liquid to a liquid passage part 2 formed in the mold 1 comprises a liquid storage part 3 equipped with a liquid temperature control mechanism which can store the temperature controlling liquid and control its temperature; a liquid feed flow path 4 for feeding the temperature controlling liquid from the liquid storage part 3 to a liquid passage part 2; and a liquid return flow path 5 for returning the temperature controlling liquid passing through the liquid passage part 2 to the liquid storage part 3. Further, the temperature controlling liquid is forcibly fed and circulated to the liquid passage part 2 and in the liquid temperature control mechanism, a coolant feed part 7 for feeding a coolant for lowering the temperature of the temperature controlling liquid to the interior of the liquid storage part 3, is provided and also a liquid discharging part 9 for discharging the excess liquid generated as a result of feeding the coolant from the coolant feed part 7 to the liquid storage part 3, to the outside of the liquid storage part 3, is provided in the liquid feed flow path 4.
