うにしている。When manufacturing a cylindrical body made of fiber reinforced plastics (hereinafter referred to as FRP), usually a reinforcing fiber impregnated with resin is wound around the surface of a cylindrical core mold using a filament winding machine, etc. After the resin has hardened, the molded product is slid onto the cylindrical core mold in the axial direction and removed.
ところが、ベローズ形状をした筒体を成形する場合には
、筒状芯型の表面にベローズの曲部分を成形する凸部が
形成されているため、成形品を筒状芯型の軸方向にスラ
イドさせて抜き取ることができない。However, when molding a bellows-shaped cylindrical body, since a convex part is formed on the surface of the cylindrical core mold to form the curved part of the bellows, it is difficult to slide the molded product in the axial direction of the cylindrical core mold. It cannot be removed.
このため、従来は、ベローズ形状とした筒体を成形する

号）。For this reason, conventionally, when molding a bellows-shaped cylindrical body, a cylindrical core mold was divided in the circumferential direction as a split core mold, and when demolding, the split core molds were individually moved toward the center. The split core mold is disassembled and removed individually.

除くようにしたのである。In order to solve the above problems, this invention forms a bellows-shaped mold by fitting a ring made of an elastic material onto the outer peripheral surface of a cylindrical core mold, and injects resin onto the outer peripheral surface of this mold. After winding the impregnated fibers and hardening and molding, the molded product was removed by sliding it along with the ring in the axial direction of the cylindrical core mold, and then the ring fitted on the inner surface of the molded product was removed. It is.
上記方法によれば、ベローズ形状の成形品を、通常の筒

抜き取ることができるので、脱型作業が極めて容易であ
る。According to the above method, the bellows-shaped molded product can be removed by sliding it in the axial direction of the cylindrical core mold in the same way as a normal cylindrical molded product, so demolding is extremely easy.
また、筒状芯型の外周面の嵌まるリングは、弾性体によ

中心方向に変形させて成形品の内面から容易に取り除く
ことができ、また、成形時の組立ての際には、筒状芯型
の外周面に容易に嵌めることができる。In addition, the ring to which the outer peripheral surface of the cylindrical core fits is made of an elastic material, so after removing the cylindrical core,
It can be deformed toward the center and easily removed from the inner surface of the molded product, and can also be easily fitted onto the outer peripheral surface of the cylindrical core during assembly during molding.
以下、この発明の実施例を、第１図に示すような円筒部

成形する三本のリング６とから成る。The mold 4 for molding the cylindrical body 1 is comprised of a cylindrical core mold 5 for molding the cylindrical portion 2 and three rings 6 for molding the bellows portion 3, as shown in FIG.

せる必要がある。After that, the bolts 7 fixing the ring 6 are removed, and the cylindrical body 1 formed as described above is slid along with the ring 6 in the axial direction and removed from the cylindrical core mold 5, as shown in FIG. . When the ring 6 is bonded to the cylindrical core mold 5 by the adhesive side, it is necessary to apply enough force to overcome the adhesive force to slide the cylindrical body 1 together with the ring 6.
次いで、上記円筒体１のベローズ部３の内側に嵌まって

、脱型を極めて短時間で行なうことができる。In the conventional manufacturing method of a bellows-shaped FRP cylinder using a circumferentially divided mold, not only does it take a lot of time to assemble the core mold and remove the mold after molding, but it also takes a long time to reuse the core mold. Since it is necessary to remove and clean the resin that has penetrated into the divided parts of the core mold, it takes a lot of time to regenerate the core mold, but according to this invention, the molded product can be processed just like a normal FRP cylinder. Since the mold can be removed by sliding it in the axial direction, the mold can be removed in an extremely short time.

ることができる。Further, since the ring forming the bellows portion is formed of an elastic material such as rubber or plastic, it can be easily fitted into the cylindrical core mold and can be easily removed after molding. Furthermore, this ring can be manufactured inexpensively from rubber or plastic, so
It can be disposable, simplifying mold cleaning and mold regeneration.
