PURPOSE:To make possible favorable releasing even when an item having a rib or the like that interferes with the movement of a split mold is produced using a mold having such a structure that the split is moved in the oblique direction of an oblique rod, by dividing the split mold into two blocks, and moving only the block having an undercut section approximately normally to the releasing direction of the molded item. CONSTITUTION:A split mold 38 can be separated downward from a movable mold 22 and is divided into an extrusion block 40 and a slide block 39. The slide block 39 is formed with an undercut section 39a forming an extended section 1a, and the extrusion block 40 is fixed to the tip of a fixed rod 35. Accordingly when releasing is effected, the slide block 39 can be moved on the upper side, where it would not engage with a rib 1b, to a position where the extended section 1a is separated completely from the undercut section 39a, and the molded item 1 can be released below the movable mold 22. |
