摘要： Fluid flow grooves (11) with a flat cross section being formed between the back surface of a metal mold (2) for blow molding and a back-up member (4) which adheres tightly to this back surface. A plurality of these fluid flow grooves (11) are provided, and these fluid flow grooves are disposed densely in parallel with partition walls (21) interposed between the grooves. Fluid inlets (12) and outlets (13) are formed in the respective fluid flow grooves (11). A heating fluid or cooling fluid enters the respective fluid flow grooves (11) via the inlets (12) from a fluid supply manifold (14). The fluid flows out of the outlets (13), enters a fluid discharge manifold (15), and is discharged to the outside. Rapid heating and rapid cooling of the metal mold (2) are performed, no irregularity occurs in temperature, and the cycle time can be shortened, so that a metal mold device for blow molding in which the energy consumption is small can be obtained.
