且つ複雑な装置が必要となる。 Conventionally, demolding of a resin tube centrifugally molded onto the inner circumferential surface of a cylindrical shape has been carried out by extracting the resin tube from the cylindrical shape in the horizontal axis direction. However, the frictional resistance due to the surface contact between the inner circumferential surface of the cylinder and the outer circumferential surface of the resin tube is large, and therefore a large and complicated device is required to extract it.

る。 That is, the present invention is a demolding device for a resin tube centrifugally molded on the inner circumferential surface of a cylindrical shape rotatable around a horizontal axis, which is capable of being fitted into one end of the cylindrical shape and capable of removing the resin tube. It has a push member that can be brought into contact with one end, a screw shaft that is relatively rotatably connected to the push member, and a nut that is screwed onto the screw shaft and can be interlocked with the cylindrical shape via a clutch, The screw shaft provides a demolding device configured to be non-rotatable and movable in the direction of the horizontal axis. According to this configuration, by turning on the clutch and transmitting the cylindrical rotational force to the nut body, the screw shaft screwed into this nut body can be advanced, and therefore the pushing member attached to this screw shaft can be moved forward. The resin tube can be pushed back and removed from the cylindrical mold through the . This allows the device for extraction to be made smaller and simpler.

している。 Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 shows the state during centrifugal molding. In other words, 1 has a cylindrical shape, is supported by a plurality of wheels 2, and has a horizontal axis 3.
It is configured to be rotatable around the . End face jigs 4 are attached to both ends of the cylindrical shape 1. Therefore, by supplying resin liquid into the cylindrical mold 1 while rotating the cylindrical mold 1 around the horizontal axis 3, a resin pipe 5 is formed on the inner peripheral surface of the cylindrical mold 1 between the both end face jigs 4.
can be centrifugally molded. FIG. 2 shows the state in which the demolding device is arranged. A straight resin tube 5 is centrifugally formed, and the tubular mold 1 is stopped from rotating and the end jig 4 is removed. Reference numeral 6 denotes a push member which can be fitted into one end of the cylindrical mold 1 and can come into contact with one end of the resin pipe 5. 7 is a screw shaft connected to the pushing member 6 so as to be relatively rotatable;
The connection is achieved by passing a small diameter portion 8 formed at the tip through a hole 9 formed in the pusher member 6, and attaching a retaining plate 10 to the protruding end. 11 is a nut body screwed onto the screw shaft 7;
It is interlocked with the cylinder 1 via a clutch (such as an electromagnetic clutch) 12. The screw shaft 7 is
It is configured to be non-rotatable and movable in the direction of the horizontal axis 3.

る。 That is, the rear end of the screw shaft 7 is connected to a movable base 14 via a support rod 13, and this movable base 14 is connected to a wheel body 15.
is guided to the rail 16 via. The screw shaft 7
A fluid supply path 17 is provided through the resin tube 5 and is configured to supply fluid into the resin tube 5 via a pump 18 .

せる。 As shown by the solid line in FIG. 2, the cylindrical mold 1 is rotated with the demolding device attached. At this time clutch 1
2 is off, so the nut body 11 does not rotate, but the push member 6 rotates. but,
Due to the configuration of the small diameter portion 8 and the hole 9, it is separated from the screw shaft 7. In this state, the clutch 12 is turned on.

し部材６も逆動し、元の位置に戻る。 Then, the rotational force of the cylindrical mold 1 is transmitted to the nut body 11, which rotates the nut body 11. As a result, the screw shaft 7 moves forward (plunging motion), and the push member 6
The resin tube 5 is pushed back through the cylindrical mold 1, and the resin tube 5 is pulled out from the cylindrical mold 1 as shown by the imaginary line in FIG. Prior to such extraction movement, fluid such as water or air is supplied through the fluid supply path 17, and the resin pipe 5 is cooled by this fluid. As a result, the resin pipe 5
Because it contracts, the extraction movement is performed with little frictional resistance. After the resin tube 5 is completely extracted, the cylindrical mold 1 is rotated in the opposite direction. As a result, the pushing member 6 also moves backward and returns to its original position.
