【発明の詳細な説明】 この発明は、樹脂管を連続的に押出成形するた

き、その規制内壁面に樹脂管の外周面を接触させ
外径を規制する場合がある。 When manufacturing resin pipes by continuously extruding resin such as vinyl chloride resin, a device with an outer diameter regulating device attached to the mouthpiece attached to the tip of the extruder immediately controls the outer diameter of the resin pipe discharged from the mouthpiece. In some cases, the outer circumferential surface of the resin pipe is guided to a regulating device, and the outer peripheral surface of the resin tube is brought into contact with the regulating inner wall surface of the regulating device to regulate the outer diameter.

の除去が困難であつた。 According to this device, the outer peripheral surface of the resin pipe is always in contact with the inner wall surface of the outer diameter regulating device, which is inconvenient, such as not being able to cut the resin pipe discharged from the mouthpiece at the start and attaching the outer diameter regulating device. Furthermore, when the resin pipe was cut, the resin clogged inside the device and was difficult to remove.

らなかつたからである。 The inventor focused on the fact that it would be convenient to install and remove the outer diameter regulating device by dividing it vertically so that it could be opened and closed. I didn't like it because it left some residue behind. Therefore, we considered making the dividing surface inclined with respect to the axis, but this could be done by attaching it to the cap,
It was a pain to remove. This is because if the splitting surface was inclined, when opening and closing the device, it would not be possible to open and close the device in a direction perpendicular to the axis of the cylindrical portion where the cap is attached, and each device would have to be set while being offset from the axial direction. be.

を特徴とする樹脂管の製造装置に存する。 This invention was made based on these points, and its gist is to extrude a resin tube from a mouthpiece attached to the tip of an extruder, and to pass it through an outer diameter regulating device to regulate the outer diameter. In the apparatus for manufacturing resin pipes, the outer diameter regulating device has an outer diameter regulating device main body which is vertically divided so as to be openable and closable, and the dividing plane is inclined with respect to the axis; The apparatus for manufacturing a resin pipe is characterized by comprising a splitting auxiliary cylinder having a dividing surface that coincides with a plane passing through an axis for attaching the apparatus main body to the base.

1 is an outer diameter regulating device main body, which has a cylindrical hollow portion and is vertically divided into semi-cylindrical bodies 21 and 22, and the dividing surface 23 thereof is inclined with respect to the axis of the cylindrical hollow portion.
If this angle of inclination is set too large, it will be difficult to open the semi-cylindrical bodies 21 and 22 while they are fitted into the resin pipe A, so the angle of inclination should be 5° or more.
The angle is preferably about 15°. Although not shown, an annular groove is bored in the cylindrical hollow inner surface of the regulating device main body 2, and this groove leads to an exhaust pipe.
When the semi-cylindrical bodies 21 and 22 of the device main body 2 are closed, the air between the inner surface and the resin pipe A is discharged,
This allows the resin pipe A to come into close contact with the cylindrical hollow inner surface of the device 2, and also allows the cooling medium to circulate in the device body 2.

This splitting auxiliary cylinder 3 is attached to the outer mold 11 in such a way that the semi-cylindrical bodies 31 and 32 fit into the attachment cylindrical part 111 of the outer mold 11, but usually it is integrated with the device main body 2 or can be detached. It can be attached to or detached from the cap 1 at the same time as the device main body 2.
Incidentally, it is convenient if a lubricant supply section is provided in this splitting auxiliary cylinder 3 to supply lubricant to the outer peripheral surface of the resin pipe A.

なるものを押出す場合などに好適に用いられる。 The resin pipe A coming out of the outer diameter regulating device main body 2 is passed through a forming tube as required, passes through a cooling water tank (not shown), and is taken up by a take-up machine. Such a device is used when extruding a resin pipe A consisting of a thick part and a thin part by setting the take-up speed of the resin pipe A in at least two stages, high speed and low speed. Suitably used.

きわめて容易となる。 As described above, in the resin pipe manufacturing apparatus of the present invention, although the outer diameter regulating device is vertically divided so as to be openable and closable, its main body is inclined with respect to the axis. It is possible to manufacture resin pipes with an excellent appearance without leaving any marks on the joints of the surfaces, and the axis of the cap can be easily attached to and removed from the cap by using a splitting auxiliary tube whose dividing surface matches the plane passing through the axis. This is possible by opening and closing in the direction perpendicular to the opening and closing directions, which makes it extremely easy.
