[0003] In the prior art, most of the building staircase molds are designed with fixed dimensions, that is, once the mold is manufactured, the width of the stairs it can produce remains fixed. However, in actual construction projects, the width of the stairs often varies due to design requirements, building specifications or space limitations. Therefore, when encountering requirements for stairs of different widths, traditional prefabricated staircase molds are unable to cope with the situation and often need to be re-prepared, which not only increases production costs, but also prolongs the construction period and reduces the utilization rate of the mold. Therefore, in response to the above problems, we propose a new type of building staircase mold. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0022] Example 1: Figure 1-Figure 4 As shown, the utility model provides a building stair mold, including a first mounting plate 1 and a second mounting plate 2, a plurality of horizontal plates 3 are fixedly connected to the front surface of the first mounting plate 1 at equal intervals, a plurality of vertical plates 31 are fixedly connected to the right surface of the horizontal plate 3 at equal intervals, an inclined plate 32 is fixedly connected to the front surface of the first mounting plate 1, a plurality of first movable grooves 21 are opened at equal intervals on the outer surface of the second mounting plate 2, a plurality of second movable grooves 22 are opened at equal intervals on the outer surface of the second mounting plate 2, the first movable grooves 21 are connected to the second movable grooves 22, a third movable groove 23 is opened on the outer surface of the second mounting plate 2, the outer surface of the horizontal plate 3 is slidably fitted with the inner surface wall of the first movable groove 21, the outer surface of the vertical plate 31 is slidably fitted with the inner surface wall of the second movable groove 22, and the outer surface of the inclined plate 32 is slidably fitted with the inner surface wall of the second movable groove 22. The surface is slidably fitted with the inner surface wall of the third movable groove 23, and a threaded screw 4 is arranged near the four corners on the front surface of the first mounting plate 1, and the outer surface of the threaded screw 4 slides through the outer surface of the second mounting plate 2 and extends to the front side. The outer surface of the threaded screw 4 is located at the rear side of the second mounting plate 2 and is threadedly connected with a first movable sleeve 41, and the outer surface of the threaded screw 4 is located at the front side of the second mounting plate 2 and is threadedly connected with a second movable sleeve 42. A first bolt 5 is installed on the top of the second mounting plate 2, and the outer surface of the first bolt 5 penetrates the top of one of the horizontal plates 3 and extends to the inside. A second bolt 51 is installed on the top of the second mounting plate 2 near the right side, and the outer surface of the second bolt 51 penetrates the top of the inclined plate 32 and extends to the inside.
[0023] The effect achieved by the entire embodiment 1 is that when using the present mold, the operator needs to adaptively adjust the width of the mold according to the required width of the staircase component, which is achieved by rotating the first movable sleeve 41 and the second movable sleeve 42 on the threaded screw 4, which rotate to the two sides of the mold respectively, driving the second mounting plate 2 to move, thereby changing the overall width of the building staircase mold, and taking out the first bolt 5 and the second bolt 51 on the second mounting plate 2. At this time, the second mounting plate 2 can be moved away from the first mounting plate 1, and as the second mounting plate 2 is released, the horizontal plate 3, the vertical plate 31 and the inclined plate 32 can slide freely along their corresponding first movable grooves 21, second movable grooves 22 and third movable grooves 23. By sliding these plates, the operator can accurately adjust the relative positions between them to adapt to different stair width requirements, and the second mounting plate 2 is firmly fixed on the first bolt 5 and the second bolt 51. On the first mounting plate 1, ensure the stability of the mold structure and the accuracy during the injection molding process. At the same time, it is necessary to tighten the first movable sleeve 41 and the second movable sleeve 42 to lock the current width setting of the mold. After the mold adjustment is completed, the injection molding operation can be carried out. The molten plastic material is injected into the interior of the building staircase mold to fill the cavity formed by the horizontal plate 3, the vertical plate 31, the inclined plate 32, etc. As the plastic cools and solidifies, the required shape of the staircase component is formed. After the injection molding is completed, it is necessary to wait for the plastic component to completely cool and solidify. Subsequently, the operator loosens the first bolt 5 and the second bolt 51 again, as well as the tightening of the second movable sleeve 42, so as to separate the various parts of the building staircase mold. The flexibility and versatility of the entire mold reduces the cost caused by frequent mold replacement, and since the mold width is adjustable, the time for re-preparing the mold due to size mismatch is reduced, thereby extending the construction period and greatly improving the reuse rate of the mold.
[0024] Example 2: Figure 1-Figure 4 As shown, two reinforcing plates 11 are symmetrically fixedly connected to the rear surface of the first mounting plate 1, and the two reinforcing plates 11 are in the shape of a triangle.
[0025] The effect achieved by the entire embodiment 2 is that the reinforcing plate 11 serves to reinforce the first mounting plate 1, and the triangular shape is more stable.
[0026] Working principle: When using this mold, according to the width of the required staircase components, the operator needs to adaptively adjust the width of the mold, rotate the first movable sleeve 41 and the second movable sleeve 42 to the two sides of the mold respectively, drive the second mounting plate 2 to move, thereby changing the overall width of the building staircase mold, and take out the first bolt 5 and the second bolt 51, move the second mounting plate 2 away from the first mounting plate 1, and with the release of the second mounting plate 2, the horizontal plate 3, the vertical plate 31 and the inclined plate 32 can slide freely along their corresponding first movable grooves 21, second movable grooves 22 and third movable grooves 23. By sliding these plates, the operator can accurately adjust the relative positions between them to adapt to different stair width requirements, and firmly fix the second mounting plate 2 on the first mounting plate 1 through the first bolt 5 and the second bolt 51 to ensure the stability of the mold structure and the accuracy during the injection molding process. At the same time, it is necessary to tighten the first movable sleeve 41 and the second movable sleeve 42 to lock the current width setting of the mold. After the mold adjustment is completed, the injection molding operation can be carried out. The molten plastic material is injected into the interior of the building staircase mold to fill the cavity formed by the horizontal plate 3, the vertical plate 31, the inclined plate 32, etc. As the plastic cools and solidifies, the required shape of the staircase component is formed. After the injection molding is completed, the operator loosens the first bolt 5 and the second bolt 51 again, as well as the fastening of the second movable sleeve 42, so as to separate the various parts of the building staircase mold. The flexibility and versatility of the entire mold reduce the cost caused by frequent mold replacement, and because the mold width is adjustable, the time for re-preparing the mold due to size mismatch is reduced, thereby extending the construction period, greatly improving the reuse rate of the mold, and the reinforcement plate 11 serves to reinforce the first mounting plate 1, and the triangular shape design will be more stable.
