Blow mold device

防止介于组合模具之间的分模线在模具夹紧力作用下移动。一种吹模装置(11)，其中，构成吹制空腔(12)的一对组合模具是一组模具，多个模具组被平行连接到模具连接板(15，16)上，使得在相邻模具组之间限定有间隙。一组合模具(13)被插装在设置于模具连接板(15)上的宽松螺栓孔(23)内的螺栓(17)以使组合模具(13)与连接板(15)沿横向相对移动的方式连接到连接板(15)上。另一组合模具(14)被定位销(18)和螺栓(17)固定连接到模具连接板(16)上。还安装有连接件，该连接件可将两个组合模具整体连接到其分模表面上并由锥形销(19)和插座(21)构成，以防止分模线的移动。 A blow mold device (11) comprises a pair of split molds forming a blow cavity (12), which are a set of molds, and a number of such sets are attached in parallel to mold attaching plates (15,16) with a defined clearance between adjacent sets. A blow mold device (11) comprises a pair of split molds forming a blow cavity (12), which are a set of molds, and a number 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 attached to the mold attaching plate (16) by positioning pins (18) and bolts (17). A joint is installed, which integrally connects the two split molds to their parting surface, and is composed of a taper pin (19) and a socket (21), for preventing the shifting of the parting line.
