Title (EN) TUBE, METHOD FOR PRODUCING TUBE, AND DIE
(FR) TUBE AINSI QUE PROCÉDÉ DE FABRICATION DE CELUI-CI, ET MATRICE
(JA) チューブ、チューブの製造方法、及び金型
Abstract:
(EN) The present invention molds a tube that is difficult to bend and has a small outer diameter by means of an easy step. The present invention has: a primary molding step for molding a primary molded body by means of performing resin molding having disposed a reinforcing member and core pin (4) in the cavity of a first die formed from a bottom mold (30) and top mold (40) for primary molding; and a secondary molding step for covering the reinforcing member by means of performing resin molding having disposed the primary molded body in the cavity of a second die having a larger internal diameter than that of the abovementioned cavity.
(FR) Selon l'invention, un tube de petit diamètre externe et peu susceptible de se plier, est formé selon un processus simple. Le procédé de fabrication de tube de l'invention inclut : une étape de moulage primaire au cours de laquelle est formé un corps moulé primaire par exécution d'un moulage en résine tel qu'un élément de renforcement et une broche-noyau (4) est disposée dans la cavité d'une première matrice formée à l'aide d'un moule inférieur (30) et d'un moule supérieur (40) destinés à un moulage primaire ; et une étape de moulage secondaire au cours de laquelle l'élément de renforcement est revêtu par exécution d'un moulage en résine tel que le corps moulé primaire est disposé dans la cavité d'une seconde matrice qui possède un diamètre interne plus grand que celui de la cavité susmentionnée.
(JA)  外径が小さく、かつ折れ曲がり難いチューブを簡易な工程によって成形する。一次成形用の下型(30)と上型(40)とで形成される第1金型のキャビティに、補強部材と中子ピン(4)とを配置した樹脂成形をすることにより一次成形体を成形する一次成形工程と、上記キャビティの内径よりも大きな内径を有した第2金型のキャビティに一次成形体を配置した樹脂成形をすることにより、補強部材を被覆する二次成形工程と、を含む。
