が行なえない。 A centrifugal molding device inserts a mandrel wrapped with reinforcing fiber cloth in advance into a mold, and then winds the reinforcing fiber cloth of the mandrel onto the inner peripheral surface of the mold while rotating the mold at a predetermined speed. After that, resin liquid and sand are supplied into the mold to perform the desired centrifugal molding. By the way, the mandrel is cantilevered by a cart, and a material supply section for supplying resin sap and sand is provided on the tip side. Additionally, piping and a drive shaft that reach the material supply section are provided within the mandrel. In order to pre-wrap reinforcing fiber cloth around such a mandrel, conventionally, as shown in FIG. It is rotated on the path 4 and the reinforcing fiber cloth 1 is transferred onto the mandrel 3. According to this type, since the roll shaft 2 side must be rotated, automation is difficult, the device becomes large-scale, and efficiency is poor. The reason for the inefficiency is that the space cannot be used effectively during the period when the roll shaft 2 side is being rotated, and during that period it must be kept quiet, and molding cannot be performed during that period.

Annular bodies 13 are fitted into both ends of the mold 10, and a molding surface 14 is formed between these annular bodies 13. The core metal 16 supported by the trolley 15 is the mold 10
A material supply section 17 is provided at the distal end thereof. This material supply section 1
7 consists of a resin liquid supply section 18, a short fiber supply section 19, a sand supply section 20, and a resin liquid supply section 21, which are arranged in order from the distal end to the proximal end side, and further includes a press roll 22 at the distal end. is provided. Incidentally, inside the mandrel 16, there are provided piping and a drive shaft (none of which are shown) that reach the material supply section 17. Ring bodies 23 and 24 are rotatably attached to the intermediate and proximal ends of the mandrel 16 via seal members 25 and 26, respectively. 27 is both ring bodies 23, 2
A cylindrical body that is connected between the four spaces and is fitted onto the core metal 16,
A liquid 28 is sealed under pressure in the gap with the mandrel 16, with seal members 25 and 26 preventing leakage. The reason why this liquid 28 is sealed is because the pressure of the liquid 28 makes the cylindrical body thinner.
The purpose is to increase the lubrication effect by expanding the core 7, and at the same time, machining of the mandrel 16 can be omitted. As the liquid 28, oil or alcohol with low viscosity is used. The intermediate ring body 23 has a valve 2.
An air vent tube 30 having a valve 31 is provided at the proximal end, and a liquid injection tube 3 having a valve 31 is provided at the proximal ring body 24.
2 is provided. 33 indicates a reinforced fiber cloth.

As shown in FIG. 4, it may be rolled onto the cylindrical body 27 while rotating the cylindrical body 27. In that case, deposit 16
Even if there are irregularities on the outer peripheral surface of the tube or bending due to cantilevering, there is always a gap between the cylindrical body 27 and the mandrel 16, and the liquid 28 is sealed in this gap. The cylindrical body 27 can be wound up and rotated lightly and smoothly.

Further, it is possible to perform winding and transfer even during molding, thereby improving efficiency. Furthermore, when rotating the cylinder, even if there are irregularities on the outer peripheral surface of the mandrel or bending due to cantilevering, the cylinder can be rotated lightly and smoothly due to the presence of liquid. .
