[0029] See attached Figures 1 to 7 , which is the main structure of a horizontal wind power hybrid tower variable thickness mold provided in this embodiment. The horizontal wind power hybrid tower variable thickness mold includes a base 1, a bottom mold 2, a side mold 3, an end mold 27 and two covers 4. Among them, the bottom mold 2, the side mold 3, the end mold 27 and the covers 4 together enclose an inner cavity to form a casting space. The outer arc surface of the horizontal wind power hybrid tower corresponds to the cover 4, and the inner arc surface corresponds to the bottom mold 2. A support 5 is respectively provided at both ends of the base 1, and a cover 4 is hinged on the upper end of each support 5; the two covers 4 are flip forms commonly used in the industry.

[0030] The base 1 is provided with three arc-shaped support ribs 6, and the bottom of the bottom mold 2 is provided with three interval adjustment plate groups 7 along its width direction, corresponding to the three support ribs 6 respectively. The adjustment plate group 7 is adjustably connected to the corresponding support ribs 6 to adjust the thickness of the inner cavity. Specifically, the adjustment plate group 7 includes a plurality of fish scale-shaped adjustment plates 8, and the plurality of adjustment plates 8 are spaced apart along the length direction of the bottom mold 2. The support rib 6 is a double-layer steel plate structure, and the adjustment plate 8 is inserted in the middle of the double-layer steel plate.

[0031] The adjustment plate 8 has a first perforation group 9, a second perforation group 10 and a third perforation group 11; correspondingly, the support rib plate 6 has a fourth perforation group 12, a fifth perforation group 13 and a sixth perforation group 14. The first perforation group 9 can be combined with the fourth perforation group 12 to correspond to the first thickness of the inner cavity, the second perforation group 10 can be combined with the fifth perforation group 13 to correspond to the second thickness of the inner cavity, and the third perforation group 11 can be combined with the sixth perforation group 14 to correspond to the third thickness of the inner cavity. The first thickness, the second thickness and the third thickness are different, that is, the mold can produce products of three different thicknesses. In this embodiment, each perforation group includes two perforations, and the perforation groups are combined in the form of aligning the perforations and connecting them by bolts 15.

[0032] The supporting ribs 6 located on both sides are provided with a plurality of first ear plates 18 on their sides. Second ear plates 19 are provided on both sides of the bottom of the bottom mold 2, corresponding to the middle of each adjustment plate 8. In other words, the number of first ear plates 18 and second ear plates 19 is the same, and the position of each second ear plate 19 is aligned with the center line of the corresponding adjustment plate 8. Each first ear plate 18 is connected to the corresponding second ear plate 19 through a positive and negative buckle tie rod 20. The curvature fine adjustment of the bottom mold 2 is achieved by tightening or loosening the positive and negative buckle tie rod 20 to shorten or lengthen the tie rod.

In this embodiment, after the positioning bolts 21 are initially installed, the verticality of the side mold is adjusted by adjusting the positioning bolts 21, and the positioning bolts 21 are welded to the support portion 17 after the adjustment is completed.

[0034] The three support ribs 6 are fixedly connected by a plurality of first reinforcing ribs 23, and the support portion 17 passes through the corresponding support ribs 6 through a plurality of tension bolts 24 and is screwed to the ends of the first reinforcing ribs 23. Optionally, among the plurality of tension bolts 24 corresponding to each support portion 17, one is a positive and negative adjustment bolt, and the rest are ordinary bolts. Preferably, the tension bolt 24 in the middle position is a positive and negative adjustment bolt. The first reinforcing rib 23 can be a steel pipe with internal threads at both ends. In this embodiment, a steel gasket is provided on the tension bolt 24 to connect the support portion 17. Two second reinforcing ribs 28 are provided at the bottom of the three support ribs 6, and two sliding components 25 are provided at the bottom of the support portion 17. The sliding components 25 can be slidably arranged at the ends of the corresponding second reinforcing ribs 28.
