DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] Please refer to Figures 1-5 The utility model provides a technical scheme: a prefabricated square pile quick demolding mechanism, including bottom plate 1, the die mechanism for producing prefabricated square pile is used to the bottom plate 1 upper end, the die mechanism includes first die plate 2, sliding slot 3, second die plate 4, first fixed block 5, hydraulic cylinder 6, second fixed block 7, reset spring 8, the bottom plate 1 upper end both sides are provided with first die plate 2, the bottom plate 1 upper end surface is set up with a plurality of sliding slots 3, the sliding slot 3 upper end is provided with second die plate 4, the bottom plate 1 upper end is fixedly arranged with first fixed block 5 on first die plate 2 side, the first fixed block 5 upper end is fixedly arranged with hydraulic cylinder 6, and the movable end of hydraulic cylinder 6 is fixedly connected with first die plate 2, the bottom plate 1 upper end both sides are fixedly arranged with second fixed block 7, and the surface of second fixed block 7 is fixedly arranged with reset spring 8, and one end of reset spring 8 close to second die plate 4 is fixedly connected with second die plate 4.

[0021] The outer side surface both sides of first die plate 2 are fixedly arranged with first extrusion block 9, and the outer side surface of second die plate 4 is fixedly arranged with second extrusion block 10, and the inclined surface of first extrusion block 9 and second extrusion block 10 mutually adheres, when first die plate 2 mutually approaches, utilizes first extrusion block 9 extrusion second extrusion block 10 to can make two second die plate 4 mutually approach, finally can make first die plate 2, second die plate 4 mutually tighten to form a die groove, to facilitate subsequent square pile grouting production;

[0022] When the reset spring 8 is in a stretched state, once the first extrusion block 9 and the second extrusion block 10 move away from each other, the spring can automatically contract and pull the second mold plate 4 away from each other, thereby automatically completing the demolding work of the mold.

[0023] A reinforcing cage 11 is provided between the first mold plate 2 and the second mold plate 4. The surface of the first mold plate 2 is provided with mounting holes 12. The two ends of the reinforcing cage 11 are movably inserted into the mounting holes 12. The mounting holes 12 can be used to fix the reinforcing cage 11 inside the square pile. The reinforcing cage 11 is movably inserted into the mounting holes 12. After the concrete is poured and solidified, the reinforcing cage 11 can be automatically fixed inside the square pile. When demolding is required, the hydraulic cylinder 6 retracts the two first mold plates 2 and moves them away from each other, so that they can be automatically separated from the reinforcing cage 11, thereby completing the demolding work.

[0024] A plurality of stabilizing blocks 13 are uniformly fixed between the hydraulic cylinder 6 and the first fixed block 5. The stabilizing blocks 13 can ensure the structural stability between the hydraulic cylinder 6 and the first fixed block 5.

[0025] The slide 3 and the second mold plate 4 are connected by a slider so that the second mold plate 4 can only move left and right along the slide 3. The slide 3 can ensure the stability of the left and right movement of the second mold plate 4.

[0026] Working principle: When using this device, the reinforcing cage 11 is fixed in the mold groove formed by the first mold plate 2 and the second mold plate 4 through the mounting hole 12. Then, grouting production can be carried out. Before grouting, a release agent should be applied to the surface of the first mold plate 2 and the second mold plate 4. After the grouting is completed and the concrete has solidified, when demolding is required, the hydraulic cylinder 6 can be contracted to move the first mold plate 2 away from each other. When the first mold plate 2 moves away from each other, the spring can automatically contract to pull the second mold plate 4 away from each other. In this way, the first mold plate 2 moves away from each other and separates from the square pile and the reinforcing cage 11, and the second mold plate 4 moves away from each other and separates from the square pile. In this way, the demolding work can be completed automatically.

[0027] When mold closing is required, the hydraulic cylinder 6 extends to bring the first mold plate 2 closer together. When the first mold plate 2 is close to each other, the first extrusion block 9 presses the second extrusion block 10 to bring the two second mold plates 4 closer together. Finally, the first mold plate 2 and the second mold plate 4 can be tightened together to form a mold groove, which facilitates the subsequent square pile grouting production.

[0028] Meanwhile, to facilitate and save on hydraulic cylinder 6, it can be as follows: Figure 5As shown, three adjacent molds share a set of hydraulic cylinders 6, and the first mold plates 2 of the three molds can be fixedly connected through connecting plates, so that the first mold plates 2 of the three molds can be easily linked on one side to facilitate mold opening and demolding; and in this way, cost can be saved.
