[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a precast concrete wall system, including a frame 6 and several unit molds (in this embodiment, it includes one first unit mold 1, five second unit molds 2, one third unit mold 3, three fourth unit molds 4, and one fifth unit mold 5). The structures of the first unit mold 1, second unit mold 2, third unit mold 3, fourth unit mold 4, and fifth unit mold 5 are as follows: Figure 2 The differences shown are for producing two different precast concrete products for electric walls 13), ten casting support platforms 17, a first end support frame 8, a second end support frame 9, a chain plate assembly 7, a mold opening and closing drive system, and five tensioning screws 20.

[0036] The frame 6 is provided with a horizontally extending travel track 25. The unit mold and the casting support platform 17 are movably set on the travel track 25 through a rolling support structure and are alternately arranged along the length of the travel track 25.

[0037] In this embodiment, a mold support 14 is provided at the bottom of the unit mold, and the mold support 14 is in rolling cooperation with the travel track 25 through the first travel roller group 11; a pouring support platform 16 is provided at the bottom of the pouring support platform 17, and the pouring support platform 16 is in rolling cooperation with the travel track 25 through the second travel roller group 15.

[0038] A casting support platform 17 is provided between two adjacent unit molds to form a casting cavity. Specifically, the opposite surfaces of the adjacent unit molds are provided with concave surfaces and contact surfaces on both sides. The concave surfaces, contact surfaces and the top surface of the casting support platform 17 together define the casting cavity. A second polyurethane pad 22 is provided between the contact surfaces, and a first polyurethane pad 19 is provided on the top surface of the casting support platform 17. The design of the pad can prevent grout leakage.

[0039] In this embodiment, the casting support platform 17 is a horizontally arranged I-beam perpendicular to the travel track 25. It is detachably connected to the casting platform bracket 16 by bolts, and its top plane is the working surface for supporting the precast power wall product 13. The travel track 25 is an I-beam, and its upper horizontal part has its top and bottom surfaces in contact with the rollers of the first travel roller group 11 and the second travel roller group 15, respectively, to form rolling pairs. The high load-bearing capacity of the I-beam ensures structural stability; the upper and lower flanges of the I-beam track form a double-sided contact rolling pair with the rollers, enhancing the track's resistance to deformation, preventing the rollers from derailing, and the double-sided support improves the smoothness of movement and reduces vibration.

[0040] The first end support frame 8 is fixed to the end of the frame 6. The second end support frame 9 is equipped with auxiliary walking wheels 10, which roll in cooperation with the walking track 25, and can be movably set on the walking track 25. The first unit mold 1 is detachably connected to the first end support frame 8, and the fifth unit mold 5 is detachably connected to the second end support frame 9.

[0041] like Figure 1 As shown, the extension and retraction direction of the chain plate assembly 7 is parallel to the travel track 25, and all unit molds and casting support platform 17 are connected in series through a linkage structure. In this embodiment, the chain plate assembly 7 includes multiple connecting plates with oblong holes; adjacent mold supports 14 and casting platform supports 16 are provided with protruding posts, which are embedded in the oblong holes of the connecting plates to form a linkage structure. The oblong holes of the connecting plates cooperate with the protruding posts, allowing adjacent components to have limited displacement along the track direction during extension and retraction, ensuring synchronous extension and retraction of multiple units and avoiding jamming.

[0042] The mold opening and closing drive system is connected to the fifth unit mold 5 for driving it to move back and forth along the travel track 25; the two ends of the tension screw 20 are detachably connected to the first end support frame 8 and the second end support frame 9 respectively.

[0043] In this embodiment, as Figure 2 and Figure 3 As shown, the mold opening and closing drive system includes a drive cylinder 12, a crossbar 24, a gear 21, and a rack 18. The drive cylinder 12 is mounted on the frame 6; the crossbar 24 is perpendicular to the travel track 25, and its shaft is connected to the fifth unit mold 5 and the piston rod of the drive cylinder 12 via a connecting plate 23; the gear 21 is rotatably mounted on the end of the crossbar 24; the rack 18 is mounted on the frame 6 and meshes with the gear 21. The drive cylinder 12 pushes the fifth unit mold 5 through the crossbar 24, and the gear 21 and rack 18 control the horizontal movement of the crossbar 24. The mechanical transmission precisely controls the mold opening and closing stroke, avoiding hydraulic system lag, and the meshing of the gear 21 and rack 18 ensures synchronized action.

[0044] The working principle of the precast concrete wall system described in this embodiment is as follows:

[0045] 1) The hydraulic cylinder extends the hydraulic rod; the fifth unit mold 5 begins to move, the gear 21 begins to rotate, and the motion system begins to work; the chain plate assembly 7 begins to extend, driving the fourth unit mold 4 to move, and so on, the third unit mold 3 and the second unit mold 2 begin to move, until the fifth unit mold 5, the fourth unit mold 4, the third unit mold 3 and the second unit mold 2 are pulled open in sequence, completing the mold opening process.

[0046] 2) After the mold opening process is completed, carefully inspect each mold and other components, remove foreign objects from the travel track 25, and apply grease to each moving part.

[0047] 3) The hydraulic cylinder retracts, the fifth unit mold 5 begins to move, the gear 21 begins to rotate, and the motion system begins to work; the chain plate assembly 7 begins to shorten, driving the fourth unit mold 4 to move, and so on, the third unit mold 3 and the second unit mold 2 begin to move, until the fifth unit mold 5, the fourth unit mold 4, the third unit mold 3 and the second unit mold 2 are pressed in sequence, completing the initial mold closing process.

[0048] 4) Using five tensioning screws 20, along with washers, spring washers, and nuts, tighten the nuts with a wrench to pull the first end support frame 8 and the second end support frame 9 towards each other, thereby completing the complete fixation of the mold.

[0049] 5) Inspect the unit mold and, after confirming that it is correct, apply a release agent to the inner wall of the casting cavity. After a certain period of time, add materials (steel bars and concrete) into the casting cavity and then tamp them down to ensure that the density of the poured materials is uniform and compact.

[0050] 6) Based on the material characteristics, check the material forming status inside the unit mold after a period of time.

[0051] 7) Repeat the mold opening process in sequence 1) to complete the mold opening of the fifth unit mold 5, the fourth unit mold 4, the third unit mold 3, and the second unit mold 2.

[0052] 8) After the mold opening process is completed, carefully check the solidification of the material product. If it meets the lifting requirements, it can be demolded and lifted out of the precast power wall product 13 with special lifting equipment and transported to the special placement area. This completes one production cycle.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
