RESIN MOLDED BODY, METHOD FOR PRODUCING THE SAME, AND INSERT TOOL FOR SHEATH CONNECTION PORT MOLDING
To perform correspondence by the same mold by suitably cutting a diameter expansion flange part even in the case the burial angle of a sheath is changed.SOLUTION: A cylindrical resin molding tube 30 with a prescribed length and a mold 31 for drawing having a tapered part 31a drawing a cylindrical part 11a having an external diameter smaller than the inside diameter of the opening edge 3a of a sheath connection tube 3 and a diameter expansion part 31b having an external diameter higher than that of the tapered part 31a and molding a diameter expansion flange part 11b are prepared. The resin molding tube 30 is heated, the heated resin molding tube 30 is inserted from the side of the diameter expansion part 31b, and pressurization is performed toward the tapered part 31a to mold a resin molded body 11' in which the cylindrical part 11a and the diameter expansion flange part 11b are integrally molded.SELECTED DRAWING: Figure 2
【課題】シースの埋設角度が変わる場合でも、拡径フランジ部を適切に切断することで、同じ金型で対応できる。【解決手段】所定長さの円筒状の樹脂成形管３０と、シース接続管３の開口端３ａの内径よりも小さな外径を有する円筒部１１ａを絞り成形する先細部３１ａ及びこの先細部３１ａよりも外径が大きく、拡径フランジ部１１ｂを成形する拡径部３１ｂを有する絞り加工用金型３１とを準備し、樹脂成形管３０を加熱し、加熱した樹脂成形管３０を拡径部３１ｂ側から挿入して先細部３１ａに向かって加圧し、円筒部１１ａ及び拡径フランジ部１１ｂが一体に成形された樹脂成形体１１’を成形する。【選択図】図２
