摘要： PURPOSE:To obtain a core mold to form a plural kinds of reducing sockets by a method wherein 3 or more core molds for forming reducing joint portions core molds for forming central portion being divided into 2 or more truncated cone shaped ring portions are joined with intermediaries of ring bodies. CONSTITUTION:3 Truncated cone shaped ring bodies 13a-13c are coupled together by means of bolts 141, 142 to form a central-portion-molding core mold 13. A ring body 15 is laid between the ring body 13c and a connection-portion-molding core mold 11', hooking parts 13c2 and projection parts 116' being coupled together by means of bolts 143. A side plate 12' is positioned in contact with a side surface of a larger diameter portion 111' of a core mold 11', hooking parts 115' and the side plates being coupled together by means of bolts 144. A side plate 12 is brought into contact with a side surface of a larger diameter portion 111 of a connection-portion- molding core mold 11, hooking parts 115 and the side plate 12 being connected together by means of bolts 145. A shaft 15 whose both ends are male-screwed is inserted into perforations 121, 121' in the inside plates 12, 12', collars 17, 17' located at the shaft being clamped through the medium of washers 13, 13' by means of bolts 20, 20' to assemble a reducing-socket-molding core mold.

摘要： PURPOSE:To simplify a core mold and to enable the efficient production of a subject joint having a high precision resulting from elimination of the need for an extensive power rotation required for a heavy mold, by performing a molding of a bent portion and a molding of a receiving portion in a separate process by the respective winding systems. CONSTITUTION:A molding of a bent portion 2 is such that the rotation of a core mold 1 for a bent portion molding causes the formation of an internal surface layer 201 comprising a mat such as glass fibre whereinto resin solution of unsaturated polyester resin or the like mixed with hardener is soaked, a reinforcing layer 202, comprising a glass fibre screen cloth, wound around the layer 201, a line layer 203 such as glass rovings, wherein resin liquid is soaked, then wound around the layer 202, and a layer 204 whereat tow such as glass fibre are dispersed over surfaces of across ends and each one end of the end surfaces encroaches on the laminar layer so formed. Aforesaid work is hardened by heating to form the bent portion 2. After said bent portion is demolded, one end 21 of the bent portion 2 is fitted in a small- sized portion 32 of a receiving portion mold 3, the bent portion 2 being secured on the receiving portion mold 3 by expanding a hollow toroidal part 36 with air fed into by pressure. The respective layers 41, 42 and 43 are formed in the manner described above with regard to the formation of the bent portion 2, the pressure applied to the toroidal part 36 being released after heating. The receiving portion 4 is formed at one end of the bent portion 2, a receiving portion 4' being provided at the other end in the same manner as described above.

摘要： PURPOSE:To provide a pipe joint of good roundness property with simple equipment and workability by fitting at least one preformed socket material to a pipe joint forming core mold, feeding a reinforced resin around the socket material and the core mold, and hardening the resin. CONSTITUTION:A glass fiber mat or the like impregnated with a resin solution of a hardener and an unsaturated polyester resin is wound around the ouside surface of a core mold 1 to form an inside surface layer 301. A glass fiber fabric reinforcement layer 302, glass robing reinforcement layer 303, and short-glass-fiber layer 304 are formed on the layer 301, hardened, and separated from a mold to form a socket member 3. A large-diametered portion 32 of the member 3 is engaged with a projection 52 of a holder 5, and fixed to a predetermined position of a straight pipe portion mold 41 with screws. Similarly, socket members 3' and 3'' are fixed to predetermined positions of a straight pipe portion mold 41' and a branch pipe portion mold 42. After resin reinforcement layers 302'-305' are formed and hardened, the core mold 1 is split and removed to obtain a reinforced resin pipe joint.

摘要： PURPOSE:To easily mass-produce reinforced resin tubular bodies whose inner configuration is complicated, by forming a reinforcing resin molding material layer around a core mold having a synthetic resin foamed body on the outer surace layer followed by the curing of the reinforcing resin molding material layer. CONSTITUTION:A reinforcing resin molding material made up of a glass fiber reinforcing material and a low-temperature curing unsaturated polyester resin liquid is wound around the tubular foamed body 1 of the core mold to form the reinforcing resin molding material layer 5, which is cured by heating it at a temperature at which the foamed body 1 constituting the core mold would not be deformed to produce the reinforced resin tubular body 6. A rotating shaft 3, a support 4, setting members 2, etc. are removed to obtain the reinforced resin tubular body 6 with the tubular foamed body 1 retained therein, and the tubular body 6 is heated with steam from the outside so that the tubular foamed body 1 can be shrinked. Then as a gap 7 is formed between the reinforced resin tubular body 6 and the tubular foamed body 1, eityer the foamed body that has been shrinked is removed as it is or it is removed after it is broken to get the reinforced resin tubular body 6.
