An object of the invention is to provide a blow mold unit and a blow molding machine which can stabilize a bottom mold clamping motion to thereby mitigate loads to be applied to a bottom mold driving mechanism and molds. A blow mold unit (10) has a construction in which, when clamping first and second blow cavity split molds (12, 14) which are fixed to first and second fixing plates (40, 50) and bottom molds (100) which are fixed to a bottom mold fixing plate (10), pressure receiving members (60) fixed to the first and second fixing plates (40, 50) are brought into engagement with the bottom plate fixing plate (110). Guide plates (120) are fixed to the bottom mold fixing plate (110), and guided members (70) capable of being brought into abutment with the guide plates (120) are supported by first and second pressure receiving plates (20, 30). The bottom mold fixing plate (110) includes a first connecting portion (116) to be connected to a bottom mold opening/closing unit (210) which is to be driven by a clamping mechanism provided to a blow molding machine, and a second connecting portion (116) to be connected to a moving and biasing member (250) which is provided to the blow molding machine (200) and moves and biases the bottom molds, which are in the closed position, in a direction in which the bottom molds are closed. |
