<p>PROBLEM TO BE SOLVED: To provide a mold which is suited for forming box-shaped resin moldings incorporating a curved pipe part internally. SOLUTION: This mold 10 comprises a slide core 20 which is arranged at a position facing an opening part 1a of the resin moldings 1 and has a core part 21a for molding the inner face side of the curved pipe part 4a and a platen 15 as a support member for guiding the slide core 20 in such a manner that the slide core 20 rotates around the curve pivot OP when the mold is clamped. In addition, a guide groove 27 which is positioned outside the moldings 1 during clamping the mold and curves, drawing an arc centered around the curve pivot CP, is provided in either of the slide core 20 or the platen 15. Further, in the other one of the slide core 20 or the platen 15, a guide shaft 23 which fits into the guide groove 27 in a freely sliding manner, is provided.</p> |
