[0019] The present application will be further described below with reference to the accompanying drawings and embodiments.
[0020] Example 1 This embodiment discloses a method for installing an arc-shaped side mold and a back rib: When machining the arc-shaped side mold 10, such as Figure 1 As shown: First, a flat plate is processed according to the unfolded dimensions. Then, slots are cut at equal intervals along the horizontal and vertical directions of the flat plate. The slots inside the two sides of the vertical direction are full holes 11, and the slots on the two sides of the vertical direction are half holes 12 with half the length of the full hole 11. Then, the center line connecting each column of full holes 11 in the horizontal direction is used as the bending line. While limiting the two sides of the bending line, force is applied to the bending line to bend and obtain the arc-shaped side mold 10.
[0021] The size and horizontal and vertical spacing of the slots on the flat plate are determined according to the curvature, thickness and material of the arc-shaped side mold 10, to ensure that the strength is not affected during use and that it will provide sufficient back support in conjunction with the back rib 20.
[0022] The slots on the flat plate are created using laser positioning and cutting.
[0023] The distance at which force is applied to the bend line is the bending distance at that location.
[0024] When machining the back rib 20, such as Figure 2 As shown: Based on the curvature of the arc-shaped side mold 10 and the lateral spacing of its slots, the back rib 20 and the protrusion along the inner arc edge of the back rib 20 are integrally cut on the flat plate to ensure that the back rib 20 can be attached to the outside of the arc-shaped side mold 10 and can be spliced laterally during assembly. The protrusions within both ends are full protrusions 21 that match the size of the full hole 11, and the protrusions at both ends are half protrusions 22 that match the size of the half hole 12.
[0025] Among them, the length of the inner arc edge of the back rib 20 must be an integer multiple of the slot on the arc-shaped side mold 10, and it must also be able to provide sufficient back support.
[0026] The back rib 20 and the protrusions are obtained by laser positioning and cutting on the flat plate.
[0027] During assembly, such as Figure 3 As shown: Both the arc-shaped side mold 10 and the back rib 20 are horizontally spliced. The two half-holes 12 form a whole hole 11 at the splicing point, and the two half-protrusions 21 form a whole protrusion 22 at the splicing point. The back rib 20 is struck from the outside and the arc-shaped side mold 10 is struck from the inside, so that the whole protrusion 21 is knocked into the whole hole 11 and the inner arc edge of the back rib 20 is completely attached to the outside of the arc-shaped side mold 10. The back ribs 20 of adjacent layers are staggered.
[0028] Specifically: First, align the protrusions with the corresponding slots, then tap the back rib 20 from the outside along the line from one end to the other. At the same time, tap the arc-shaped side mold 10 from the inside, so that the protrusions are inserted into the slots one by one along the line, and the inner arc edge of the back rib 20 and the outer side of the arc-shaped side mold 10 gradually fit together along the line.
[0029] Specifically: use a soft hammer to strike, and strike in a radial direction as much as possible.
[0030] This method can precisely fit the back rib 20 and the arc-shaped side mold 10. The back rib 20 is cut as a whole without bending, thus ensuring dimensional accuracy. The arc-shaped side mold 10 is obtained by bending a flat plate. Even if the initial arc accuracy is not high, in the subsequent assembly process, under the positioning action of the protrusions and slots, the back rib 20 is struck from the outside and the arc-shaped side mold 10 is struck from the inside. On the one hand, the protrusions overcome frictional resistance and enter the slots, and on the other hand, it has a shaping effect on the arc-shaped side mold 10. As long as the protrusions and slots cooperate... This method allows the inner arc edge of the back rib 20 to be completely attached to the outer side of the arc-shaped side mold 10. The back rib 20 can be tightly installed on the arc-shaped side mold 10. When processing the arc-shaped side mold 10, the center line connecting the centers of each row of holes 11 in the transverse direction is used as the bending line. After bending, the outer end of the hole 11 is slightly enlarged and the inner end is slightly narrowed. After the protrusion is inserted into the slot, it is an interference fit, and the two are firmly connected. In this method, the back ribs 20 of adjacent layers are staggered, which can eliminate continuous seams and improve the overall rigidity.
[0031] The curved side mold 10 and the back rib 20 can be made of multi-layer plywood or composite fiberboard.
[0032] Example 2 This embodiment discloses an installation structure for an arc-shaped side mold and a back rib, which is obtained from the installation method of the arc-shaped side mold and back rib in Embodiment 1 above.

The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
