<p><P>PROBLEM TO BE SOLVED: To provide a blow molding mold wherein (i) the mold structure is simplified (shortening of design period, manufacturing period), (ii) the maintainability is improved (in particular, reduction of work for clogging of a cooling water line), (iii) weight is reduced compared to conventional ones, and (iv) the molding quality is maintained, and the transfer of split lines is prevented as far as possible. <P>SOLUTION: The blow molding mold 10 provides a molding molded along the shape of a cavity formed inside by combining a plurality of mold members 1. Outer surfaces of the mold members 1 have a convex raised par 14, a partition wall 16 set at the highest part of the raised part or near the part, and a surrounding wall 17 set on a peripheral edge of the outer surfaces of the mold members to surround the raised part. A medium inflow port 11 and a medium outflow port 12 penetrating through the surrounding wall are provided on both right and left sides across the partition wall 16 at a predetermined face part of the surrounding wall 17. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
