    • PURPOSE: To obtain a FRP product containing roving densely, by a method wherein a cylindrical net body comprised of a tube wound around in the longitudinal direction to form a ring shape and a resin liquid is poured into a mold in which the ring shaped body is inserted.
      CONSTITUTION: Rovings 10A, 10B are wound around a tube 1 while being woven like a wire net to form a cylindrical net body 16 on the tube 1 which is lowered on a shaft center 4. The cylindrical net element 16 is wound around the tube 1 in the longitudinal direction to form a ring shaped body 17. A resin liquid 20 is supplied into a pair of molds 18A, 18B with the ring shaped body 17 deformedly inserted into the molding space thereof. Simultaneously, degassing 21 is conducted from a space 19 and after the resin liquid 20 is hardened, it is taken out of the molds 18A, 18B in order to obtain a fiber reinforced resin product 22. In other words, a fiber reinforced resin product containing a ring shaped body molded with dense roving is obtained.

    • PURPOSE:To obtain the titled equipment by which the molded product of a high dimensional accuracy and not leaving an unnecessary resin part is obtained, by arranging the closed curve-shaped injection gate for injecting a synthetic resin to the entire periphery of the end face of a cylindrically molded product simultaneously and a heat insulator between said gate and a mold. CONSTITUTION:The ring like injection gate 24 connected to the ring like runner 23 which succeeds a vertical runner 21 and a branched runner 22 is shaped and a manifold 13 and a runner block 14 are heated by the heaters, etc. Each runner 21, 22, 23 and the injection gate 24 are heated and heat insulated against the cooled parts of the molds 31, 32 with a heat insulating plate 16. The open-close of the injection gate 24 is done by a ring valve 15 and it is prevented that an unnecessary resin part remains at the molded product 26 taken out from the molds 31, 32.
    • 目的:为了获得具有高尺寸精度并且不留下不必要的树脂部件的成型品的标题设备,通过将合成树脂注入的闭合曲线形注入门布置在端面的整个外周 同时具有圆柱形模制产品,并且在所述浇口和模具之间具有隔热材料。 构成:连接到成为垂直流道21和分支流道22的环状流道23的环状喷射门24成形,并且歧管13和流道块14被加热器等加热。每个流道21,22 23和喷射门24通过隔热板16被加热并与绝热板16的模具31,32的冷却部分进行隔热。注入门24的开闭由环形阀15完成,并且防止了 从模具31,32取出的成型品26中残留有不需要的树脂部分。
