Abstract
The shifting of the parting line between split molds due to mold clamping 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 locating 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.
