[0029] Example 1

[0030] like Figs. 1-3 As shown, this embodiment provides a flat precast stair mold with a combined bottom mold, including: a base 1 and a bottom mold 2 disposed above the base 1, and further including: fixed side molds 3 disposed on both sides of the bottom mold 2, a front end cover 4 disposed at one end of the bottom mold 2 and a rear end cover 5 disposed at the other end of the bottom mold 2. The bottom mold 2 and the fixed side molds 3 are both detachable segmented combined connection structures, which facilitates the adjustment of mold size and shape, adapts to the precast stair requirements of different specifications, and improves the versatility of the mold.

[0031] The bottom mold 2 includes a first section 21 disposed at one end of the fixed side mold 3 and a last section 22 disposed on the opposite side of the first section 21. The first section 21 and the last section 22 are fixedly connected by a plurality of fixing components 23.

[0032] Meanwhile, the fixing component 23 includes: a fixing plate 231 for connecting the first segment 21 and the last segment 22, and a plurality of first fasteners 232 disposed on the fixing plate 231.

[0033] The fixing plate 231 increases the stress-bearing area at the connection between two adjacent bottom mold sections 2, enabling the entire mold to withstand a larger load, ensuring that the mold does not deform or break during the casting process, and extending the service life of the mold.

[0034] In this embodiment, the fixed side mold 3 includes: an initial segment 31 adapted to the first segment 21 and a tail segment 32 disposed on the opposite side of the initial segment 31 and adapted to the last segment 22, wherein the initial segment 31 and the tail segment 32 are fixedly connected by a connecting component 33.

[0035] In this embodiment, the connecting component 33 includes: a connecting plate 331 for connecting the initial segment 31 and the tail segment 32, and a plurality of second fasteners 332 disposed on the connecting plate 331. The first fastener 232 and the second fastener 332 can both preferably be bolts, which have simple structure, are easy to disassemble and assemble, and have low cost.

[0036] In this embodiment, the connecting plate 331 increases the stress-bearing area at the connection between two adjacent fixed side molds 3, enabling the entire mold to withstand a larger load, ensuring that the mold does not deform or break during the casting process, and extending the service life of the mold.

[0037] In this embodiment, a two-section combined structure is adopted, namely, the left and right bottom molds 2 and the fixed side molds 3, which can produce stairs with fewer steps.

[0038] In this embodiment, the segmented modular mold can be disassembled into smaller parts for transportation and storage, reducing transportation costs and storage space.

[0039] Of course, the assembly and disassembly of segmented modular molds are more flexible, reducing the time required for mold installation and disassembly. At the same time, this structure allows for the quick replacement of damaged or worn parts, reducing maintenance and downtime, thereby improving work efficiency.

[0040] In addition, the front cover 4 and the rear cover 5 are fixedly connected to the ends of the fixed side mold 3, which further ensures the stability and firmness of the fixed side mold 3, and prevents protrusions or cracks, thus ensuring the flatness of the staircase surface.

[0041] Example 2

[0042] like Figs. 4-6 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0043] The bottom mold 2 also includes an intermediate section 24 disposed between the first section 21 and the last section 22.

[0044] The first section 21 and the middle section 24, and the middle section 24 and the last section 22 are all fixedly connected by the fixing component 23. The fixing plate 231 can ensure that there are no protrusions or cracks at the connection, thereby ensuring the flatness of the two sides of the processed stair section.

[0045] Meanwhile, the fixed side mold 3 further comprises a middle section 34 arranged between the initial section 31 and the tail section 32, the initial section 31 and the middle section 34 are fixedly connected through the connecting assembly 33, and the tail section 32 and the middle section 34 are fixedly connected through the connecting assembly 33, the connecting plate 331 can ensure that the connection part is free of protrusions, cracks and other problems, thereby ensuring the flatness of the bottom surface of the processed stair section.

[0046] Of course, the three-section combined structure, i.e. the left-middle-right three-section bottom mold 2 and the fixed side mold 3 can be used to produce a stair with more steps.

[0047] In addition, the middle section 24 is arranged corresponding to the middle section 34, and the two are matched, and the middle section 24 and the middle section 34 can be provided with multiple groups, and then combined correspondingly to form a four-section combined structure, etc., and can be designed to have one or more step widths according to different step numbers, so as to meet the pouring requirements of different step number difference stairs, and have wide application range.

[0048] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
