PURPOSE:To obtain the mold device capable of suppressing the generation of water contaminant in a circulating path, while the temperature-controlling capacity of the mold in the temperature circuit which has excess flowing amount is improved by providing the flowing amount-controlling valve for regulating the flowing amount in each branching pipe respectively. CONSTITUTION:After the flowing amount V fed from a thermostat 2 has circulated in each part of a mold and has achieved heat-exchange by branching into each branching pipe arrangement, the flowing amount returns to the thermostat 2. Such circulating path is formed. By throttling the flow amount-controlling valve 4 of the branching pipe arrangement in which excess amount is flowing the flowing amount is reduced to necessary amount, and the discharging pressure from the thermostat is increased as shown by marks. Consequently, in the branching pipe which has less flowing amount, the pressure-difference is increased as arrows, thereby increasing its flowing amount. The temperature- regulation of the whole mold may be kept uniformly. |
