Abstract
A cooling device () includes radiation thermometers (to), a plurality of nozzle parts, a plurality of electromagnetic valves (Vto V), and a control device (). The radiation thermometers detect pre-cooling temperatures that are temperatures at a plurality of places on the mold before cooling water is sprayed from the plurality of nozzle parts to the mold. The control device individually sets a cooling time to each of the plurality of places on the mold based on a deviation between the pre-cooling temperature at the place on the mold and a target temperature and controls the electromagnetic valves based on the cooling times individually set to the plurality of respective places on the mold.
