DETAILED DESCRIPTION

[0022] like Figure 1-5 As shown, a carbon ring winding mold comprises a side plate 1, a partition plate 2, and an insert 3. A first step 4 is provided at the center of a plane of the side plate 1, and a second step 5 is provided at the center of a plane of the insert 3. The shape and size of the upper surface of the first step 4 are smaller than the shape and size of the plane on the side plate 1 where the first step 4 is provided, and the shape and size of the upper surface of the second step 5 are smaller than the shape and size of the plane on the insert 3 where the second step 5 is provided. The height of the first step 4 is equal to the height of the second step 5. The front side wall of the partition plate 2 is in close contact with the plane on the first step 4 facing away from the side plate 1 and the plane on the second step 5 facing away from the insert 3. The geometric center of the whole formed by the plane on the first step 4 facing away from the side plate 1 and the plane on the second step 5 facing away from the insert 3 coincides with the geometric center of the front side wall of the side plate 1. The plane on the first step 4 facing away from the side plate 1 The shape and size of the whole formed by the plane on the second step 5 facing away from the insert 3 is smaller than the shape and size of the front side wall of the partition 2, the side wall on the second step 5 facing away from the first step 4 is a protruding arc-shaped surface, and the side wall on the first step 4 facing away from the second step 5 is also a protruding arc-shaped surface, the insert 3 is provided with a second through hole 7, the side plate 1 is provided with a first through hole 6, and the partition is provided with a fifth through hole matching the first through hole 6 and the second through hole 7, the axis of the first through hole 6 is perpendicular to the side of the first step 4 facing away from the side plate 1, the axis of the second through hole 7 is perpendicular to the side of the second step 5 facing away from the insert 3, the first bolt 16 passes through the first through hole 6 and a fifth through hole to lock the partition 2 and the side plate 1 together, and the second bolt 17 passes through the second through hole 7 and another fifth through hole to lock the partition 2 and the side plate 1 together.

[0023] In the present application, when in use, after the insert 3 and the side panel form an integral body, the side of the second step 5 facing away from the side panel 1 and the side of the first step 4 facing away from the side panel 1 form an overall plane, and then this overall plane is concentrically fitted with the front side wall of the partition 2. Since the shape and size of the upper surface of the first step 4 are smaller than the shape and size of the plane on which the first step 4 is set on the side panel 1, and the shape and size of the upper surface of the second step 5 are smaller than the shape and size of the plane on which the second step 5 is set on the insert 3, after the side panel 1, the partition 2 and the insert 3 form an integral mold, the surface of the mold body has a receiving groove for accommodating the carbon ring 2, and the bottom wall of the receiving groove is the side wall of the integral body formed by the combination of the first step 4 and the second step 5, and one side wall of the receiving groove is the side wall of the side panel 1. The plane of the first step 4 is set, and the other side wall of the receiving groove is the plane on the partition 2 facing the side plate 1. After that, the side plate 1, the partition 2, and the insert 3 are locked together by the first bolt 16 and the second bolt 17, so that the carbon yarn impregnated with glue can be wound on the integral side wall formed by the combination of the first step 4 and the second step 5. After winding to the specified number of turns, the entire mold is placed in a baking oven for baking. After baking, the second bolt 17 is unscrewed, so that the insert 3 can be removed from the partition 2 first. Since the contact surface between the insert 3 and the carbon ring 22 is not large, it does not require too much force. After the insert 3 is removed, the inner surface of the carbon ring 22 is exposed, which is convenient for holding. After that, the first bolt 17 is unscrewed, and it is easier to remove the carbon ring 22 from the side plate 1. This solves the problem that in the process of disassembling the mold for manufacturing the carbon ring in the traditional way, the carbon ring is easily damaged due to excessive force that is difficult to control.

[0024] As a preferred embodiment, a protrusion 8 is provided on the plane of the insert 3 facing the side plate 1, and a groove 9 is provided on the plane of the side plate 1 facing the insert 3 to cooperate with the protrusion 8. In this way, by providing the protrusion 8 and the groove 9, the side plate 1 can limit the insert 3 to a certain extent, preventing the insert from rotating during the process of rotating the second bolt 17.

[0025] As a preferred method, a glue overflow groove 10 is provided on the upper surface of the side panel 1, and the glue overflow groove 10 is parallel to the plane of the first step 4 facing away from the side panel 1, and a preset distance is provided between the plane of the side panel 1 on which the first step is provided and the glue overflow groove 10. The molding of the carbon ring 22 may be accompanied by excessive resin dosage or overflow caused by the extrusion of the cover plate 18. Since it is difficult to remove the surface of the side panel 1 or the partition plate 2, excessive processing in the later stage may damage the receiving groove, and incomplete processing may affect the next mold product, so adding the glue overflow groove 10 can improve this problem.

[0026] As a preferred mode, one of the partition plates 2 is combined with two of the side plates 1 and two of the inserts 3, the front side wall of the partition plate 2 is in close contact with the first step 4 on one of the side plates 1 and the second step 5 on one of the inserts 3, and the rear side wall of the partition plate 2 is in close contact with the first step 4 on another of the side plates 1 and the second step 5 on another of the inserts 3. With this arrangement, two carbon rings 22 can be manufactured at the same time.

[0027] As a preferred embodiment, a chamfer is provided on the upper surface of the side plate 1 facing the partition plate 2, and a chamfer is also provided on the upper surface of the partition plate 2 facing the side plate 1. The chamfer is provided in this way to facilitate the removal of the insert 3 during disassembly.

[0028] As a preferred embodiment, the cover plate 18 is further included. The side plate 1 is provided with a third through hole 11 perpendicular to the upper surface. The cover plate 18 is provided with a fourth through hole 12. A third bolt 19 passes through the third through hole 11 and the fourth through hole 12 to lock the cover plate 18 on the side plate 1.

[0029] As a preferred embodiment, a blind hole 14 is provided on the front side wall of the partition plate 2 away from the first through hole 6, and a positioning protrusion 15 matching the blind hole 14 is provided on the plane of the first step 4 facing away from the side plate 1. This arrangement prevents the side plate 1 from rotating relative to the partition plate 2 during the process of rotating the first bolt 16.
