。While holding the proximal end of the elastically deformable, cylindrical large diameter inner surface mold 8 in the opening on the large diameter molding surface 2 side of the rotary mold 1, the guide tube is inserted through the fixture 9. 10 is installed. The large diameter inner surface mold 8 is made of fluorine rubber, silicone,
It is made of urethane, etc., and can swing between a position facing the large-diameter molding surface 2 and a position that fits inside the guide tube 10, and usually swings to a position that fits inside the guide tube 10 due to its own elasticity. There is. Further, an annular convex portion 11 is integrally formed on the molding surface Ba. A short outer push tube 12 and a long inner push tube 13 are fitted into the guide tube 10 . In such a centrifugal molding apparatus, as shown in FIG. A large diameter portion (socket portion) 14 is centrifugally molded by supplying resin onto the large diameter portion molding surface 2. Next, the outer pushing cylinder 12 is pushed in, and as shown in FIG. Then, as shown in the imaginary line in FIG.
is centrifugally molded. Next, with the inner pushing tube 13 pushed in and positioned inside the intermediate diameter portion 15, resin is supplied onto the small diameter portion molding surface 4 of the gate as shown in FIG.
is centrifugally molded. As a result, a joint tube IT with different diameters as shown in FIG. 4 can be manufactured. As described above, according to the present invention, a joint pipe of different diameters can be formed quickly and reliably.

成形する異径継手管の成形方法。1 In a state where an elastically deformable large-diameter inner surface mold is held in an opening on the large-diameter molding surface side of a rotary mold having a large-diameter molding surface, an intermediate-diameter molding surface, and a small-diameter molding surface. In a centrifugal molding device in which a guide tube is attached and an outer push tube and an inner push tube are fitted to the guide tube, first, both push tubes are retracted and the large diameter inner mold is retracted, and then the large diameter A resin is supplied onto the diameter molding surface to centrifugally mold the large diameter part, and then an outer pushing cylinder is pushed in to mold the inner surface of the large diameter part with the large diameter mold, and then onto the intermediate diameter molding surface. The method involves centrifugally molding the intermediate diameter portion by supplying resin, then pushing an inner push-in cylinder to position it inside the intermediate diameter portion, and then supplying resin onto the small diameter portion molding surface to centrifugally mold the small diameter portion. Method for forming diameter joint pipes.
