[0001] The utility model relates to the technical field of stair tread foot protection production devices, in particular to a production mould for stair tread foot protection bricks. Background Art
[0002] At present, when laying stairs, the length, width and height of the stair steps are usually measured first, and then two stone slabs are cut out accordingly, and then one stone slab is pasted together, and then the two stone slabs are pasted together, so that the two stone slabs are vertically connected, and the connection between the two stone slabs is not handled well, which is easy to crack and cause the stone slabs to fall off, and the stone slabs on the plane of the stair steps are easily bumped, resulting in separation from the connection between the two stone slabs and causing damage.
[0003] Stair decoration is inseparable from the use of stair tread footing bricks. Stair tread footing bricks are generally in a right-angle shape. At present, during the production process of stair tread footing bricks, two stone slabs are generally cut out first, and then the two stone slabs are glued together in a vertical form. However, in fact, the bonding effect at the connection between the two stone slabs is limited, which can easily cause cracking and falling off at the connection between the two stone slabs. In order to avoid this problem, the present application specially proposes a production mold for stair tread footing bricks, so as to facilitate the integrated production of stair tread footing bricks and avoid the above problems.

[0005] Each of the limiting components includes a short shaft fixedly connected to the L-shaped buckle cover, the short shaft is coaxially rotatably connected to a collar, and the collar is integrally fixedly connected to a limiting plate that matches the limiting groove on the corresponding side thereof.
[0006] Preferably, a large rounded corner is inverted at the turning point of the L-shaped lower mold, and a small rounded corner is inverted at the turning point of the L-shaped buckle cover.
[0007] The beneficial effects of the utility model are:
[0008] When the present application is in use, the L-shaped buckle cover and the L-shaped lower mold can be quickly spliced to ensure production efficiency. The L-shaped buckle cover and the L-shaped lower mold are spliced together to form a production mold for casting stair tread footing bricks. The casting material is poured into the casting chamber of the L-shaped lower mold and waited to solidify. After that, the mold is demolded to produce an L-shaped, i.e., right-angled, stair tread footing. The manufactured stair tread footing is connected as an integral whole to ensure its overall quality. Compared with the traditional splicing type, it has better strength and quality. The present application has a simple structure, is easy to use, and the assembly and disassembly of the mold are simple and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is combined with Figure 1-7 The specific implementation methods of the utility model are further described in detail.
[0019] Embodiment 1, the technical solution is that when the present application is in use, the L-shaped buckle cover 1 and the L-shaped lower mold 2 can be quickly spliced to ensure production efficiency. The L-shaped buckle cover 1 and the L-shaped lower mold 2 are spliced to form a production mold for casting stair tread footing bricks. The casting material is poured into the casting chamber 3 of the L-shaped lower mold 2 and waited to solidify. After that, the mold is demolded to produce an L-shaped, i.e., a right-angled stair tread footing. The manufactured stair tread footing is connected as an integral whole to ensure its overall quality. Compared with the traditional splicing type, it has better strength and quality. The present application has a simple structure, is easy to use, and the assembly and disassembly of the mold are simple and quick.
[0020] Embodiment 2, based on embodiment 1, specifically, when the present application is used, firstly, a mold release agent is applied to the inner surface of the L-shaped buckle cover 1 and the casting chamber 3 of the L-shaped lower mold 2, so as to facilitate demoulding after casting, and then the L-shaped buckle cover 1 and the L-shaped lower mold 2 are spliced, and during splicing, the positioning holes 8 on the L-shaped buckle cover 1 are correspondingly plugged with the positioning posts 7 on the retaining edge 4, and the caliper 6 is slidably inserted into the card slot 5, and the positioning posts 7 and the positioning holes 8 are convenient for determining the connection and positioning of the L-shaped buckle cover 1 and the L-shaped lower mold 2. The card slot 5 and the card fit cooperate to limit the L-shaped buckle cover 1 to be tightly connected with the vertical part of the L-shaped lower mold 2, and the cooperation between the limiting rod and the limiting groove 9 of the limiting component 10 can limit the L-shaped buckle cover 1 to be tightly connected with the horizontal part of the L-shaped lower mold 2. The collar 13 of the limiting component 10 is rotatably mounted on the short shaft 12, so that the limiting plate 14 connected to the collar 13 can be turned to rotate. The limiting plate 14 can be turned into the limiting groove 9 to lock the horizontal part of the L-shaped buckle cover 1 and the L-shaped lower mold 2. According to the above steps, the L-shaped buckle cover 1 and the L-shaped lower mold 2 can be assembled to quickly form a production mold for stair tread footing bricks. The upper end of the production mold automatically leaves a pouring port 17, and the pouring material can be fed in from the pouring port 17.
[0021] After pouring is completed and allowed to stand and solidify, demoulding can be carried out. During demoulding, the limiting plate 14 is rotated to be out of the limiting groove 9, so that the L-shaped buckle cover 1 can be separated from the L-shaped lower mold 2. The operation is simple and quick.
[0022] Embodiment 3, on the basis of embodiment 2, the turning point of the L-shaped lower mold 2 is provided with a large rounded corner 15, and the turning point of the L-shaped buckle cover 1 is provided with a small rounded corner 16, which makes the turning point of the manufactured step foot protection brick more rounded, which is not only beautiful but also improves the safety during use. The vertical part of the L-shaped lower mold 2 is fixedly connected with a plurality of support legs 11 evenly distributed along its length direction. Since the assembled production mold is L-shaped, the stability is poor, and the support legs 11 are provided to ensure its stability during use.
