PURPOSE:To obtain a mold for blow molding, which is excellent in heat conductivity and further excellent in releasability, stability to size and workability, by forming at least a part of a cavity with a graphite material. CONSTITUTION:The title mold is constituted of: a mold main body 12 made of a metal material; a graphite member 13 fitted into the mold main body 12 to constitute a cavity 11 and made of a graphite material; stationary members 14 adapted to fix the graphite member 13 fitted into the mold main body 12 to constitute a part of the cavity 11 and made of a metal material; and screws 17 for being screwed into the screw holes 16 of the stationary members 14 and into the screw holes 15 of the mold main body 12 and made of a metal material. Accordingly, in the mold 10 for blow molding, the graphite member 13 can be demounted by removing the screws 17, and the graphite member 13 alone, which relatively tends to be worn, can be easily replaced. Further, by forming at least a part of the cavity 11 with the graphite material, the heat conductivity of the cavity 11 is enhanced. |
