DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0018] In one embodiment, see Figure 1A casting formwork for civil engineering construction comprises a base 1, a molding cavity 2 is provided on the top of the base 1, two symmetrically distributed pressing plates 8 are slidably connected inside the molding cavity 2, the bottoms of the pressing plates 8 are slidably connected to the bottom of the molding cavity 2, and the two relatively distributed side walls of the pressing plates 8 are slidably connected to the two relatively distributed inner walls of the molding cavity 2 respectively, a rotating rod 6 runs through the inside of the base 1, one end of the rotating rod 6 is connected to a rotating part 5, the rotating part 5 is used to drive the rotating rod 6 to rotate, the rotating rod 6 is connected to the two pressing plates 8 through a driving mechanism 3, the driving mechanism 3 is used to drive the two pressing plates 8 to move relative to each other, a trough body is provided at the bottom of the molding cavity 2, a top plate 7 is slidably connected inside the trough body, the shape of the top plate 7 is adapted to the shape of the trough body, the top plate 7 is connected to the rotating rod 6 through a supporting mechanism 4, and the supporting mechanism 4 is used to drive the top plate 7 to move upward.

[0019] When the pressing plate 8 moves to the specified position, the top of the top plate 7 is flush with the bottom of the molding cavity 2. At this time, concrete can be poured into the molding cavity 2. After the concrete is molded to a certain extent, the rotating part 5 drives the rotating rod 6 to rotate in the opposite direction. The rotating rod 6 drives the top plate 7 to move upward through the supporting mechanism 4, and the molded concrete is ejected from the molding cavity 2 through the top plate 7. At the same time, the rotating rod 6 drives the two pressing plates 8 to move away from each other through the driving mechanism 3, so that the pressing plate 8 is separated from the concrete, which can effectively reduce the friction between the molding cavity 2 and the concrete, making it convenient for the top plate 7 to eject the molded concrete from the molding cavity 2, and then facilitate the staff to take the molded concrete out of the molding cavity 2.

[0020] See also Figure 1 The driving mechanism 3 includes a plurality of first elastic components 31 fixedly connected to the inner wall of the molding cavity 2, the other end of the first elastic component 31 is fixedly connected to the pressing plate 8, the pressing plate 8 is fixedly connected to a slide bar 32, the end of the slide bar 32 away from the pressing plate 8 is fixedly connected to a baffle 33, the baffle 33 is fixedly connected to a traction rope 34, wherein a winding roller 35 is fixedly connected to the outside of the rotating rod 6, and the winding roller 35 is fixedly connected to the traction rope 34;

[0021] When it is necessary to pour concrete, the winding roller 35 is driven to rotate by the rotating part 5, and the winding roller 35 pulls the baffle 33 through the traction rope 34. The baffle 33 drives the pressure plate 8 to move closer to each other through the sliding rod 32. When the pressure plate 8 moves to the specified position, the rotating rod 6 stops rotating. At this time, concrete can be poured into the molding cavity 2, and the baffle 33 is pulled by the traction rope 34, which can effectively improve the stability of the pressure plate 8. During the concrete pouring process, the first elastic component 31 is in a stretched state. The first elastic component 31 can be a spring. After the concrete is formed, the rotating rod 6 rotates in the opposite direction, and the first elastic component 31 automatically resets, thereby driving the pressure plates 8 to move away from each other, thereby separating the pressure plates 8 from the concrete, making it convenient for the top plate 7 to eject the concrete from the molding cavity 2.

[0022] See also Figure 2 The base 1 is provided with a channel 37 inside, and the traction rope 34 passes through the channel 37. A guide roller 36 is fixedly connected inside the channel 37, and the guide roller 36 is slidably connected to the traction rope 34;

[0023] The traction rope 34 is guided by the channel 37 and the guide roller 36 , which can effectively reduce the friction between the traction rope 34 and the base 1 , thereby increasing the service life of the traction rope 34 .

[0024] See also Figure 3 The supporting mechanism 4 is fixedly connected to the bottom of the top plate 7 with symmetrically distributed supporting rods 41, the lower ends of the supporting rods 41 extend into the interior of the base 1, and the outsides of the supporting rods 41 are fixed with fixed plates 43, the top of the fixed plates 43 is fixedly connected with a second elastic component 42, and the upper end of the second elastic component 42 is fixedly connected to the top of the base 1, wherein the rotating rod 6 is fixedly connected with an extrusion assembly, and the extrusion assembly is used to extrude the supporting rods 41;

[0025] During the concrete forming process, the extrusion assembly no longer squeezes the support rod 41. Under the action of the fixed plate 43 and the second elastic component 42, the top of the top plate 7 is flush with the bottom of the forming cavity 2, thereby avoiding the interference of the top plate 7 with the concrete forming. When the concrete is formed to a certain extent, the rotating rod 6 squeezes the support rod 41 through the extrusion assembly, and the support rod 41 pushes the formed concrete out of the inside of the forming cavity 2 through the top plate 7, thereby facilitating the staff to take the formed concrete out of the inside of the forming cavity 2.

[0026] See also Figure 1 and Figure 3 The extrusion assembly includes a rotating disk 44 fixed to the outside of the rotating rod 6 and symmetrically distributed, the side of the rotating disk 44 is in contact with the lower end of the support rod 41, and a groove 45 is provided on the side of the rotating disk 44;

[0027] During the concrete forming process, the bottom of the support rod 41 is in contact with the groove 45 of the turntable 44, and the top of the top plate 7 is flush with the bottom of the forming cavity 2. When the concrete is formed to a certain extent, the rotating rod 6 drives the turntable 44 to rotate, and the circular side surface of the turntable 44 squeezes the support rod 41, so that the support rod 41 drives the top plate 7 to move upward, and then the formed concrete is ejected from the inside of the forming cavity 2.

[0028] Working principle: When the casting template is in use, the rotating part 5 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the winding roller 35 and the turntable 44 to rotate. The winding roller 35 pulls the baffle 33 through the traction rope 34, and the baffle 33 drives the pressing plate 8 to approach each other through the sliding rod 32. When the pressing plate 8 moves to the specified position, the rotating rod 6 stops rotating. At this time, the bottom of the support rod 41 is in contact with the groove 45 of the turntable 44. Under the action of the fixed plate 43 and the second elastic component 42, the top of the top plate 7 is flush with the bottom of the forming cavity 2, avoiding the interference of the top plate 7 with the concrete forming. After that, concrete can be poured into the molding cavity 2. After the concrete is molded to a certain extent, the rotating part 5 drives the rotating rod 6 to rotate in the opposite direction, and the rotating rod 6 drives the turntable 44 to rotate. The circular side surface of the turntable 44 squeezes the support rod 41, so that the support rod 41 drives the top plate 7 to move upward, and then the molded concrete is ejected from the molding cavity 2. At the same time, the traction rope 34 no longer pulls the baffle 33, and the pressing plates 8 move away from each other under the action of the first elastic component 31. The pressing plates 8 are automatically separated from the concrete, so that it is convenient for the top plate 7 to eject the concrete from the molding cavity 2.
