PROBLEM TO BE SOLVED: To provide a mold cooler capable of evenly cooling a cylindrical mold over an axial direction.SOLUTION: A coolant supply pipe (6) comprises a common pipe (10) disposed on outside of a mold (5); and plural branch pipes (11A-11C) disposed inside of the mold (5) and branched from the common pipe (10). Discharge ports (16A-16C) for discharging the coolant are respectively formed on axial end parts of the respective branch pipes (11A-11C), and whole lengths (L1-L3) of the branch pipes (11A-11C) are different from each other, respectively (L1>L2>L3). |
