PROBLEM TO BE SOLVED: To materialize a mold with a cooling pipe in which the valve of a fluid coupler for feeding cooling liquid can smoothly be opened even when residual heat remains. SOLUTION: In the mold 10, the fluid couplers 14a, 14b having valves closed in a non-connected time and opened by pressure from the outside are mounted on ends of a cooling liquid pipe 12. The mold 10 has an air tank 18 (pressure governor) keeping the pipe inner pressure at a certain value or less at the cooling liquid pipe 12. In the mold 10, the air tank 18 keeps the pipe inner pressure at a certain value or less even if remaining heat remains, causing no increase of resistance when opening the valves. The mold 10 allows smooth opening of valves of the fluid couplers 14a, 14b for feeding cooling liquid even if remaining heat remains. COPYRIGHT: (C)2010,JPO&INPIT
