Blow molding mold unit

A blow molding mold unit comprising:

• a plurality of blow molds each including:
• a pair of split molds forming a plurality of cavities arranged in a row in a first direction;
• a plurality of bottom molds respectively corresponding to the cavities;
• and a bottom mold fixing plate to which the plurality of bottom molds are fixed, the plurality of blow molds being arranged in a second direction perpendicular to the first direction;
• first fixing members holding split molds that are arranged at both end positions in the second direction, the first fixing members being fixed to a mold clamping plate;
• second fixing members arranged between the first fixing members, and to which split molds other than the split molds fixed to the first fixing members are fixed;
• pressure receiving members fixed to the first fixing members and the second fixing members at both end positions outward of the pair of split molds in the first direction;
• and
• a coupling jig that prevents the pair of split molds from being mold-opened, the coupling jig being detachably attached across two adjacent pressure receiving members included in the pressure receiving members that are in contact with each other.
