<p>The shifting of the parting line between split molds due to mold tightening force is prevented. A blow mold device (11) wherein a pair of split molds forming a blow cavity (12) are a set of molds, and a plurality of such sets are attached in parallel to mold attaching plates (15, 16) with a clearance defined between adjacent sets. One split mold (13) is attached by bolts (17) inserted in bolt holes (23) in the form of loose holes in the mold attaching plate (15) in such a manner as to allow relative lateral shifting of the split mold (13) and mold attaching plate (15). The other split mold (14) is fixedly attached to the mold attaching plate (16) by positioning pins (18) and bolts (17). A joint is installed that integrally connects the two split molds to their parting surface and that is composed of a taper pin (19) and a socket (21) for preventing the shifting of the parting line.</p> |
