[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-3 In this embodiment of the present invention, a side mold device for precast concrete components includes two side plates 1 and an end plate 2 located at the ends of the two side plates 1. The outer side of the side plate 1 is integrally formed with an outwardly protruding first fixing ear 3, and the two sides of the end plate 2 are integrally formed with outwardly protruding second fixing ears 4. A through hole is provided at the center of the first fixing ear 3 and the second fixing ear 4. A locking bolt passing through the inside of the first fixing ear 3 and the second fixing ear 4 is inserted into the inner wall of the through hole. A locking nut is threaded to one end of the outer wall of the locking bolt. An alignment mechanism is distributed at the docking position of the side plate 1 and the end plate 2. A demolding mechanism is formed at the end of the end plate 2 away from the side plate 1.

[0016] In this embodiment: First, when making precast concrete components, the side plate 1 and the end plate 2 are aligned by an alignment mechanism. At this time, the first fixing lug 3 on the side plate 1 and the second fixing lug 4 on the end plate 2 are aligned. Then, the locking bolt is passed through the through holes inside the first fixing lug 3 and the second fixing lug 4. Then, the locking nut is threaded onto the outer wall of the locking bolt. A tool (such as a wrench) is used to connect with the locking nut and rotate the locking nut. The locking nut is locked during the rotation until the hexagonal head at one end of the outer wall of the locking bolt is pressed against the second fixing lug 4 and the locking nut is pressed against the outer wall of the first fixing lug 3. The connection between the side plate 1 and the end plate 2 is completed, and the precast concrete components can then be made.

[0017] After the precast concrete component is formed, the locking bolts and locking nuts are removed, and then the demolding mechanism is pulled outward. The two parts of the demolding mechanism collide and generate an outward pulling force, which can separate the end plate 2 from the side plate 1 without the need to use a pry bar.

[0018] Please refer to this carefully. Figure 1 and Figure 2 The alignment mechanism includes mating grooves 10 at both ends of the side plate 1. The end plate 2 near the side plate 1 has an integrally formed mating block 9 protruding inward. A sealing element is provided at the contact position between the inner wall of the mating groove 10 and the mating block 9.

[0019] In this embodiment: when the side plate 1 and the end plate 2 are connected, the connecting block 9 is aligned with the connecting groove 10. After alignment, the end plate 2 is pushed, and the end plate 2 drives the connecting block 9 to connect with the connecting groove 10. After the connection is completed, the locking bolts and locking nuts are used for connection. At this time, the sealing element located on the inner wall of the connecting groove 10 is deformed by compression, which can improve the sealing of the connection position of the end plate 2 and the side plate 1.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The demolding mechanism includes a sliding rod 5 fixedly installed on the end plate 2 away from the side plate 1. The end of the sliding rod 5 away from the end plate 2 is integrally formed with a force plate 6. An impact block 7 is slidably connected to the outer wall of the sliding rod 5. A handle 8 is fixedly installed on the top of the impact block 7.

[0021] In this embodiment: after the precast concrete component is formed, when demolding, first remove the locking bolts and locking nuts, then hold the handle 8, the handle 8 drives the impact block 7 towards the force plate 6 until the impact block 7 contacts the force plate 6. At this time, under the action of the impact force, the force plate 6 drives the end plate 2 through the sliding rod 5, so that the end plate 2 can be separated from the side plate 1. Then, use the rod body, the rod body passes through the two first fixing ears 3 on the side plate 1, and then pull the rod body, the rod body drives the side plate 1 to separate from the precast concrete component through the first fixing ears 3.

[0022] Please refer to this carefully. Figure 3 The impact block 7 has a sliding hole 11 inside that is slidably connected to the outer wall of the sliding rod 5. The sliding hole 11 and the vertical cross section of the sliding rod 5 are rectangular.

[0023] In this embodiment: when the impact block 7 is pulled by the handle 8, the impact block 7 slides along the outer wall of the sliding rod 5 through the sliding hole 11, and the end plate 2 is separated by sliding impact.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
