Description

Technical Field

[0001] The embodiment of the present invention relates to the technical field of vertical staircase moulds, and in particular to a staircase mould. Background Art

[0002] With the continuous introduction of relevant national policies, the prefabricated building system is developing rapidly across the country. Prefabricated buildings are to produce the corresponding prefabricated building components in the processing plant, and then transport the prefabricated components to the construction site for assembly. Through this system, the purpose of short construction period, low cost and high efficiency can be achieved. In the prefabricated building component factory, the quality of the staircase mold determines the dimensional accuracy, visual quality, production cycle and other issues of the prefabricated staircase. Therefore, it is particularly important to make the prefabricated staircase mold easy to operate, low cost, high efficiency and high quality.

[0003] In the existing vertical staircase steel mold, the left end mold and the right end mold are both independent structures, which are opened and closed by rotating around the axis. The mold opening and closing requires manual rotation of the left end mold and the right end mold. Each time a component is produced, it needs to be opened once, and then the prefabricated staircase component is taken out, and then the end mold is closed and bolted for assembly. This method is inefficient and labor-intensive.

[0004] When the end molds are opened and closed, the left and right end molds need to be repeatedly positioned, which greatly affects the accuracy of the prefabricated stair components. In actual production, the left and right end molds are often opened and closed, and the long-term wear of the left and right end molds and the bottom molds causes the gap between the left and right end molds and the bottom mold to become larger and larger, and cement mortar leaks from the gap, reducing the service life of the mold.

DETAILED DESCRIPTION

[0023] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships should be regarded as within the scope of implementation of the present invention without substantially changing the technical content.

[0025] A staircase mould, such as Figure 1 and Figure 2 As shown, it includes a bottom mold 1, a fixed side mold 2 fixedly arranged on the bottom mold 1, and a movable side mold 3 arranged opposite to the fixed side mold 2.

[0026] The two ends of the fixed side mold 2 are respectively the first end 21 and the second end 22, and the two ends of the movable side mold 3 are respectively the third end 31 and the fourth end 32. The first end 21 is fixedly connected to the left end mold 4, and the fourth end 32 is fixedly connected to the right end mold 5.

[0027] The fixed side mold 2 includes a first flat plate 23 and a first inclined plate 24 and a second inclined plate 25 fixedly connected at both ends of the first flat plate 23. The first inclined plate 24 and the second inclined plate 25 are inclined in opposite directions. A side of the first flat plate 23 close to the movable side mold 3 is provided with a trapezoidal pattern adapted to the shape of the stairs. The left end mold 4 is fixedly connected to a side of the first inclined plate 24 close to the movable side mold 3 and is perpendicular to the first inclined plate 24.

[0028] The movable side mold 3 includes a second flat plate 33 and a third inclined plate 34 and a fourth inclined plate 35 fixedly connected to both ends of the second flat plate 33. The third inclined plate 34 and the fourth inclined plate 35 are inclined in opposite directions. The third inclined plate 34 is parallel to the first inclined plate 24, and the fourth inclined plate 35 is parallel to the second inclined plate 25. The right end mold 5 is fixedly connected to a side of the fourth inclined plate 35 close to the fixed side mold 2 and is perpendicular to the fourth inclined plate 35.

[0029] When the molds are closed, the prefabricated staircase component is located between the fixed side mold 2 and the movable side mold 3. Since the first flat plate 23 is provided with staircase patterns, the prefabricated staircase component can be formed by closing the molds.

[0030] like Figure 1 and Figure 2As shown, both ends of the fixed side mold 2 and the movable side mold 3 are provided with a clamping assembly 6 that can fix the fixed side mold 2 and the movable side mold 3 together. The clamping assembly 6 ensures the sealing between the fixed side mold 2 and the movable side mold 3, so that the stair prefabricated components can be more accurate.

[0031] The clamping assembly 6 includes a fixed block 61 fixedly connected to the end of the first inclined plate 24 and a clamping block 62 fixedly connected to the end of the movable side mold 3. The fixed block 61 and the clamping block 62 are at the same height. A clamping rod 611 is horizontally rotatably connected to the fixed block 61. The clamping block 62 is provided with a clamping groove 621 for the clamping rod 611 to be inserted, and the clamping groove 621 extends in the horizontal direction.

[0032] By rotating the clamping rod 611, the clamping rod 611 can be inserted into the clamping groove 621 to fix the fixed side mold 2 and the movable side mold 3. The clamping rod 611 and the clamping groove 621 are interference-fitted to ensure the stability of the fixation.

[0033] There are four groups of clamping assemblies 6, which are evenly distributed at both ends of the fixed side mold 2 and the movable side mold 3. This can further improve the sealing performance when the mold is closed.

[0034] like Figure 1 and Figure 2 As shown, in order to further improve the precision of the fixed side mold 2 and the movable side mold 3 when closing the mold, a positioning assembly 7 is further provided at the ends of the movable side mold 3 and the fixed side mold 2.

[0035] The positioning assembly 7 includes a first positioning piece 71 fixedly connected to the end of the first inclined plate 24, a second positioning piece 72 fixedly connected to the end of the movable side mold 3, and a positioning groove 721 for inserting the first positioning piece 71 is formed on the second positioning piece 72. The positioning groove 721 is a "V"-shaped groove, and one end of the first positioning piece 71 close to the positioning groove 721 is in a "V" shape that matches the shape of the positioning groove 721.

[0036] When the mold is closed, the first positioning piece 71 can be inserted into the positioning groove 721 to achieve the function of guiding and positioning, thereby ensuring the accuracy of the mold closing between the fixed side mold 2 and the movable side mold 3.

[0037] In this embodiment, the first positioning plate 71 is not limited to being fixed at the end of the first inclined plate 24, but can also be fixed at the end of the bottom mold 1 and the upper end of the first inclined plate 24. The position of the second positioning plate 72 can be changed accordingly according to the position of the first positioning plate 71 to achieve the effect of improving accuracy.

[0038] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
