Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1

[0027] like Figures 1 to 4 The mold shown includes a bottom mold 1, side molds 2, end molds 3, and a cover plate 4. There are two side molds 2 and two end molds 3. The end molds 3 are installed on the left and right sides of the bottom mold 1 via bolt assemblies, and the side molds 2 are installed on the front and rear sides of the bottom mold 1 via bolt assemblies. Figure 2 As shown, limiting devices 9 for controlling the opening and closing angle of end mold 3 or side mold 2 are provided at the connection between end mold 3 and bottom mold 1 and at the connection between side mold 2 and bottom mold 1. Cover plate 4 is an integral cover plate. Cover plate 4 is installed on the top of end mold 3 and side mold 2. Several lifting rings 41 for hoisting cover plate 4 are symmetrically arranged on both sides of the top of cover plate 4. Cover plate 4 is installed and disassembled by using tools such as cranes through lifting rings 41. An arc-shaped cavity is formed between bottom mold 1, side mold 2, end mold 3 and cover plate 4. The arc-shaped cavity is the cavity for casting precast components. Precast components of the shaft are made by injecting concrete and other materials into the arc-shaped cavity.

[0028] Specifically, at least four lifting rings 41 are provided on the top of the cover plate 4.

[0029] Specifically, such as Figure 1 As shown, the cover plate 4 has an opening 42 in the middle for casting component materials.

[0030] Specifically, such as Figure 4 As shown, the end mold 3 is provided with several bending mandrels 31 and bending mandrel fixing devices 32. The bending mandrels 31 are used to form arc-shaped through holes in the precast components, which facilitates the splicing and installation of the precast components.

[0031] Specifically, such as Figure 1 and Figure 4 As shown, several mold support components 13 are provided on both sides of the bottom mold 1. By connecting the lifting rings or hooks to the support components, the mold can be moved and transported using tools such as cranes, which facilitates the movement and transportation of the mold.

[0032] Specifically, several fasteners are provided around the cover plate 4 to achieve a tight connection between the cover plate 4 and the end mold 3, and between the cover plate 4 and the side mold 2.

[0033] Specifically, the bolt assembly includes a hinge bolt 6, a fastening bolt 7, and an adjusting bolt 8. The hinge bolt 6 is used to adjust the opening angle of the end mold 3 and the side mold 2 relative to the bottom mold 1. The adjusting bolt 8 is used to adjust the size of the arc-shaped cavity of the mold during mold installation. The fastening bolt 7 is used for the fastening connection between the side mold 2 and the bottom mold 1, the end mold 3 and the bottom mold 1, and the side mold 2 and the end mold 3.

[0034] Specifically, the opening and closing bolt 6 is a bolt with both positive and negative threads. The bottom mold 1 is equipped with a nut with a negative thread corresponding to the opening and closing bolt 6, while the side mold 2 and end mold 3 are equipped with nuts with positive threads corresponding to the opening and closing bolt 6. The opening and closing bolt 6 is used to control the opening and closing of the end mold 3 or the side mold 2. Limiting devices 9 are provided at the connection points between the end mold 3 and the bottom mold 1, and between the side mold 2 and the bottom mold 1, to control the opening and closing angle of the end mold 3 or the side mold 2. The limiting devices 9 limit the maximum opening angle of the end mold 3 or the side mold 2, providing a safety protection function.

[0035] Specifically, the adjusting bolt 8 serves a positioning function, used for positioning and installation between the side mold 2 and the bottom mold 1, and between the side mold 2 and the end mold 3. Controlling the fixed position of the end mold 3 and the side mold 2 by adjusting the adjusting bolt 8 is equivalent to adjusting the tilt angle of the end mold 3 and the side mold 2 relative to the bottom mold 1 when they are fixed. This allows the size of the arc-shaped cavity formed between the bottom mold 1, the side mold 2, the end mold 3, and the cover plate 4 to be adjusted according to the needs of the precast component. After adjustment, a welded fixing plate ensures that the adjusting bolt 8 does not rotate during mold use.

[0036] When the fastening bolt 7 is used for fastening the connection between the side mold 2 and the bottom mold 1 and the end mold 3 and the bottom mold 1, the fastening bolt 7 is used in conjunction with the adjusting bolt 8. When it is used for fastening the connection between the side mold 2 and the end mold 3, the end mold 3 and the side mold 2 are provided with through holes or threaded holes for installing the fastening bolt 7 at the contact parts of the end mold 3 and the side mold 2.

[0037] Example 2

[0038] As a further improvement to Embodiment 1, the bottom of the bottom mold 1 is provided with several adjustable level supports 11. The horizontal state of the mold can be adjusted by adjusting the level supports 11.

[0039] Specifically, multiple attached vibrators are installed at intervals on both sides of the bottom surface of the bottom mold 1, with the attached vibrators on both sides being staggered. For example... Figure 3 As shown, several mounting seats 5 for attached vibrators are arranged in a zigzag pattern on the bottom surface of the bottom mold 1. Attached vibrators are installed at corresponding positions on the bottom mold 1 via the mounting seats 5. The attached vibrators are attached gas vibrators.

[0040] Specifically, the air inlets of multiple attached vibrators on the same side face the same direction, while the air inlets of attached vibrators on both sides face opposite directions. This arrangement of the attached gas vibrators ensures a more uniform distribution of vibration force, effectively eliminates air bubbles in the concrete, and guarantees the strength of the components. Furthermore, this arrangement of air inlets facilitates the connection of the air distribution pipes.

[0041] Specifically, each air inlet is connected via a vent pipe, and the main air inlet 12 of the vent pipe is located on the side of the bottom mold 1. The size and position of the main air inlet 12 can be adjusted according to the actual application.

[0042] The specific working state of the precast component mold for vertical shafts provided by this utility model is as follows:

[0043] When closing the mold, the foundation is first leveled using the adjustable leveling support 11 to ensure the mold is in a horizontal production state. During mold closing, the end mold 3 is closed first, followed by the side mold 2. First, the end mold 3 is closed using the opening and closing bolts 6, then the side mold 2 is closed using the opening and closing bolts 6. After the end mold 3 and side mold 2 are closed, the dimensions of the arc-shaped cavity are adjusted using the adjusting bolts 8. After adjustment, the side mold 2 and end mold 3, the side mold 2 and bottom mold 1, and the end mold 3 and bottom mold 1 are securely connected using the fastening bolts 7, completing the mold closing process. After mold closing, the release agent is evenly applied into the arc-shaped cavity of the mold. After application, a wire cage is placed according to the needs of the precast component, and the cover plate 4 is hoisted and secured.

[0044] Concrete and other precast component materials are injected through the opening 42 in the middle of the cover plate 4. During the injection process, the attached vibrator is turned on to ensure that the concrete can quickly and evenly fill the arc-shaped cavity, while vibrating out air bubbles to ensure the quality of the precast component. After filling, wait for the component to form. When the component strength meets the requirements, the mold is opened. The mold opening sequence is the reverse of the mold closing sequence. When opening the mold, first loosen the fasteners of the cover plate 4, connect the crane to the lifting ring 41 of the cover plate 4, and lift the cover plate 4 as a whole with the crane. Then loosen the fastening bolts 7 of the side mold 2 and open the side mold 2 with the opening and closing bolts 6. Then loosen the fastening bolts 7 of the end mold 3 and open the end mold 3 with the opening and closing bolts 6. After the mold is fully opened, the precast component is lifted out of the mold by the crane to complete the demolding of the precast component.

[0045] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
