DETAILED DESCRIPTION

[0030] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0031] See also Figure 1 and Figure 2The molding device 1 for prefabricated guardrails in one embodiment of the present application can at least facilitate demoulding and improve the structural integrity of the molded prefabricated guardrail 2. Specifically, the molding device 1 includes a mold mechanism 10, which includes a frame 100, two side template assemblies 200, a first drive assembly 300, two clamping plate assemblies 400 and a second drive assembly 500. Each side template assembly 200 can be movably arranged on the frame 100, and the two side template assemblies 200 are relatively spaced apart. The direction in which one side template assembly 200 moves away from the other side template assembly 200 is the demoulding direction a, and the direction in which one side template assembly 200 moves toward the other side template assembly 200 is the clamping direction b. The first drive assembly 300 is arranged on the frame 100, and the first drive assembly 300 is used to drive the two side template assemblies 200 to move a first demoulding distance along the demoulding direction a, and then drive the side template assemblies 200 to rotate in a direction away from each other. Each clamping plate assembly 400 can be movably arranged on the frame 100, and two clamping plate assemblies 400 are arranged at a relative interval, and two side formwork assemblies 200 can be located between the two clamping plate assemblies 400 and together enclose a pouring space. The second driving assembly 500 is arranged on the frame 100, and the second driving assembly 500 is used to drive the clamping plate assembly 400 to rotate in a direction away from the pouring space. Figure 2 and Figure 4 As shown, for the side template assembly 200 on the left, the demoulding direction a is toward the left, and the mold closing direction b is toward the right; for the side template assembly 200 on the right, the demoulding direction a is toward the right, and the mold closing direction b is toward the left.

[0032] When in use, the first drive assembly 300 drives the two side formwork assemblies 200 to move along the mold closing direction b, and the second drive assembly 500 drives the two clamping plate assemblies 400 to rotate relative to the frame 100, so that the two side formwork assemblies 200 and the two clamping plate assemblies 400 together enclose a casting space. Then pour concrete into the casting space. After the concrete solidifies, the first drive assembly 300 drives the side formwork assembly 200 to move the first demoulding distance along the demoulding direction a, and then continues to drive the side formwork assembly 200 to rotate in a direction away from each other. Since the side formwork assembly 200 is provided with an avoidance hole for the reserved steel bar to pass through, or a positioning column structure for forming a reserved hole, the first drive assembly 300 drives the side formwork assembly 200 to move the first demoulding distance along the demoulding direction a, so that the reserved steel bar exits the avoidance hole or the positioning column exits the reserved hole of the prefabricated guardrail 2, and then continues to rotate the side formwork assembly 200 to achieve complete demoulding of the side formwork assembly 200. At the same time, the second driving assembly 500 drives the clamping plate assembly 400 to rotate in a direction away from the casting space, so as to realize demoulding of the clamping plate assembly 400, and facilitate the subsequent handling of the prefabricated guardrail 2. During the demoulding process of the mold mechanism 10, the driving side template assembly 200 moves outward first, which can avoid direct rotation, which may cause the reserved steel bar to be unable to pass through the avoidance hole or the positioning column to damage the hole wall of the reserved hole during the rotation process. By driving the side template assembly 200 to move outward first and then rotate, the convenience of demoulding is improved, and the integrity of the molding of the prefabricated guardrail 2 is ensured.

[0033] See also Figures 2 to 4In one embodiment, the side template assembly 200 includes a template body 210, a connecting member 220, a rotating shaft 230 and a limiting member 240. The connecting member 220 is connected to one end of the template body 210. The rotating shaft 230 and the limiting member 240 are both arranged on the side of the connecting member 220 away from the template body 210. The direction of the limiting member 240 toward the rotating shaft 230 is the demoulding direction a, and the axis of the rotating shaft 230 intersects with the demoulding direction a. The frame 100 is formed with a rotating groove 110, a connecting groove 120 and a limiting groove 130. The rotating groove 110 is connected with the limiting groove 130 through the connecting groove 120. The direction of the limiting groove 130 toward the rotating groove 110 is the demoulding direction a. The connecting groove 120 penetrates the frame 100 and forms a rotating opening 122 on the side of the template body 210. In the mold closing and casting state, the stopper 240 is located in the stopper groove 130, and the rotating shaft 230 is at least partially or completely located in the rotating groove 110. In the demolding state, the first driving assembly 300 is used to drive the template body 210 to move along the demolding direction a, the rotating shaft 230 moves along the demolding direction a into the rotating groove 110, the stopper 240 moves into the connecting groove 120 and is aligned with the rotating opening 122, and the first driving assembly 300 drives the template body 210 to continue to move, so that the rotating shaft 230 rotates in the rotating groove 110 and drives the template body 210 to rotate in the direction away from the template assembly 200 on the other side and drives the stopper 240 to rotate in the direction of the rotating opening 122.

[0034] By setting the positional relationship between the rotating shaft 230 and the stopper 240 and the rotating groove 110 and the stopper groove 130 on the frame 100, when the first driving assembly 300 drives the template body 210 to move, the stopper 240 is located in the stopper groove 130, thereby limiting the template body 210 to move only. At this time, the first demoulding distance of the template body 210 can be controlled by controlling the moving distance of the stopper 240 to the rotating opening 122. When the stopper 240 moves into the connecting groove 120, the limiting effect of the stopper groove 130 and the stopper 240 is eliminated, and the rotating shaft 230 can rotate in the rotating groove 110 again, and then the first driving assembly 300 can drive the template body 210 to rotate relative to the frame 100 through the rotating shaft 230. At this time, the stopper 240 can rotate out of the rotating opening 122 around the axis of the rotating shaft 230 without interfering with the rotation of the rotating shaft 230. By virtue of the different positions of the rotating shaft 230 and the limiting member 240 at different times, the template body 210 is effectively moved first and then rotated.

[0035] Specifically, in the demolding state, the first driving assembly 300 is used to drive the template body 210 to move along the demolding direction a, the rotating shaft 230 moves into the rotating groove 110 and abuts against the inner wall of the rotating groove 110 facing the limiting groove 130, and the limiting member 240 moves into the connecting groove 120 and is aligned with the rotating opening 122. By the rotating shaft 230 abutting against the inner wall of the rotating groove 110, the stability and reliability of the rotation of the rotating shaft 230 can be improved, thereby improving the stability of the rotation of the template body 210.

[0036] See also Figure 6 In this embodiment, the first driving assembly 300 includes a driving unit 310, a first moving member 320 and a first linkage member 330, a second moving member 340 and a second linkage member 350. One end of the first linkage member 330 is rotatably connected to a template body 210, and the other end is rotatably connected to the first moving member 320. One end of the second linkage member 350 is rotatably connected to another template body 210, and the other end is rotatably connected to the second moving member 340. The driving unit 310 is used to drive the first moving member 320 and the second moving member 340 to move along the demoulding direction a or the mold closing direction b. When the first moving member 320 is driven to move by the driving unit 310, when the limiting member 240 is located in the limiting groove 130, the first moving member 320 drives the template body 210 to move along the demoulding direction a through the first linkage member 330. When the stopper 240 moves into the connecting groove 120, the limiting effect of the stopper 240 is released, and the first moving member 320 continues to move, and can drive the template body 210 to rotate around the axis of the rotating shaft 230 through the first linkage member 330, and then the driving unit 310 only needs to drive the first moving member 320 to move, so as to achieve the effect of first moving and then rotating the template body 210 when demolding, without switching the driving mode of the driving unit 310 according to the active position of the template body 210. Similarly, the driving unit 310 drives the second moving member 340 and the second linkage member 350 in the same way to drive the other template body 210 to move.

[0037] Specifically, the driving unit 310 is used to drive the first moving member 320 and the second moving member 340 to move synchronously in opposite directions or toward each other. The driving unit 310 synchronously drives the first moving member 320 and the second moving member 340 to operate synchronously, thereby improving the demoulding and clamping efficiency of the two template bodies 210. In other embodiments, there may be two driving units 310, and the two driving units 310 drive the first moving member 320 and the second moving member 340 to move respectively.

[0038] See also Figure 2 , Figure 4 and Figure 6In one embodiment, the driving unit 310 includes a driving power source 311, a transmission gear set 312, a first moving rack 313 and a second moving rack 314. The first moving rack 313 is connected to the first moving member 320, the second moving rack 314 is connected to the second moving member 340, and the first moving rack 313 and the second moving rack 314 are both meshed with the transmission gear set 312. The driving power source 311 is used to drive the transmission gear set 312 to rotate, so as to drive the first moving rack 313 and the second moving rack 314 to move synchronously in opposite directions or toward each other. The transmission gear set 312 is used to realize the synchronous movement of the first moving rack 313 and the second moving rack 314 in opposite directions or toward each other, thereby realizing the synchronous movement of the first moving member 320 and the second moving member 340 in opposite directions or toward each other.

[0039] In one embodiment, the first moving rack 313 and the first moving member 320 can be an integral structure, or the first moving rack 313 and the first moving member 320 can also be a split structure, and can achieve synchronous movement after being connected. Similarly, the second moving rack 314 and the second moving member 340 can be an integral structure, or the second moving rack 314 and the second moving member 340 can also be a split structure, and can achieve synchronous movement after being connected.

[0040] In this embodiment, the number of the first moving rack 313 and the second moving rack 314 is two, the two first moving racks 313 are arranged at intervals, and the two second moving racks 314 are respectively located on the outsides of the two first moving racks 313 and are respectively arranged at intervals from the first moving racks 313. The transmission gear set 312 includes a driving gear 3121, a first gear 3122 and two second gears 3123. The driving gear 3121 is meshed with the first gear 3122 and is located between the two middle first moving racks 313. Each second moving rack 314 is meshed with an adjacent first moving rack 313 through a second gear 3123. The driving power source 311 is used to drive the driving gear 3121 to rotate forward or reverse. The two first moving racks 313 are connected to the first moving member 320, and the two second moving racks 314 are connected to the second moving member 340. By setting two first moving racks 313 to synchronously drive one template body 210 to move, the reliability of driving the template body 210 can be improved. Similarly, by using two second moving racks 314 to synchronously drive another template body 210 to operate, the reliability of driving the template body 210 can be improved. The moving directions of each first moving rack 313 and second moving rack 314 are limited by the driving gear 3121, the first gear 3122 and the two second gears 3123 to achieve synchronous movement toward or away from each other. During use, it is only necessary to control the driving power source 311 to drive the driving gear 3121 to rotate forward or reverse.

[0041] In one embodiment, the number of the first moving member 320 and the first linkage member 330 is at least two, each first linkage member 330 is connected to a first moving member 320, each first linkage member 330 is arranged at intervals along the length direction of the template body 210, and each first moving member 320 is connected to two first moving racks 313. The number of the second moving member 340 and the second linkage member 350 is at least two, each second linkage member 350 is connected to a second moving member 340, each second linkage member 350 is arranged at intervals along the length direction of the template body 210, and each second moving member 340 is connected to two second moving racks 314. Since the length dimension of the prefabricated guardrail 2 is large, which leads to the large length dimension of the template body 210, the reliability of the drive can be improved by arranging at least two first moving members 320 and the first linkage member 330 to synchronously drive the template body 210 to move.

[0042] Specifically, one end of each first moving member 320 is connected to a first moving member, and each first moving rack 313 is also connected to the first moving member, and the synchronous movement of each first moving member 320 can be achieved by driving the first moving member to move. Similarly, one end of each second moving member 340 can also be connected to a second moving member, and each second moving rack 314 is also connected to the second moving member. In other embodiments, the first moving member can be omitted, and the second moving member can also be omitted.

[0043] For example, in this embodiment, the number of the first moving member 320 and the first linkage member 330 are both two, and the two first linkage members 330 are evenly spaced and arranged on one template body 210. The number of the second moving member 340 and the second linkage member 350 are both two, and the two second linkage members 350 are evenly spaced and arranged on the other template body 210.

[0044] See also Figures 6 to 8In one embodiment, a driving cavity 140 is further provided on the frame 100, and the driving cavity 140 is located on the side of the rotating shaft 230 facing away from the template body 210. The driving unit 310 is arranged in the driving cavity 140. A first moving groove 150 and a second moving groove 160 are further provided on the frame 100. The length directions of the first moving groove 150 and the second moving groove 160 are both in the demolding direction a. The first moving groove 150 and the second moving groove 160 are both located between the driving cavity 140 and the rotating groove 110, and one end of the first moving groove 150 and one end of the second moving groove 160 are both in contact with the driving cavity. 140 is connected, the other end of the first movable groove 150 passes through one side wall of the frame 100, and the other end of the second movable groove 160 passes through the other side wall opposite to the frame 100, one end of the first movable member 320 is inserted into the first movable groove 150 and can move in the first movable groove 150, and the other end extends out of the first movable groove 150 and is rotatably connected to the first linkage member 330, one end of the second movable member 340 is inserted into the second movable groove 160 and can move in the second movable groove 160, and the other end extends out of the second movable groove 160 and is rotatably connected to the second linkage member 350. By setting the driving cavity 140, the installation of the driving unit 310 can be easily realized, and by setting the first movable groove 150 and the second movable groove 160, the installation and mobile drive of the first movable member 320 and the second movable member 340 can be easily realized. Moreover, by setting the driving cavity 140 at the top, the first movable groove 150 and the second movable groove 160 at the middle, and the rotating groove 110, the connecting groove 120 and the limiting groove 130 at the bottom, interference of the movement of each component can be avoided, and the linkage movement between the components can be effectively realized.

[0045] See also Figure 1 In one embodiment, there are two second drive assemblies 500, and the two second drive assemblies 500 are respectively used to drive the two clamping plate assemblies 400 to rotate. By providing two second drive assemblies 500 to respectively drive the two clamping plate assemblies 400 to rotate, it is convenient to control the demoulding separately and ensure the reliability of demoulding.

[0046] Specifically, one end of each second driving assembly 500 is rotatably connected to the corresponding clamping plate assembly 400, and the other end is rotatably connected to the frame 100, and the second driving assembly 500 can be extended to drive the corresponding clamping plate assembly 400 to rotate relative to the frame 100. For example, the second driving assembly 500 can be a hydraulic driving structure, or the second driving assembly 500 can also be an electric push rod or other structures.

[0047] In other embodiments, the number of the second drive assembly 500 may be one, and one second drive assembly 500 drives the two clamping plate assemblies 400 to rotate synchronously toward or away from each other. For example, the second drive assembly 500 may be a gear rack structure, which is synchronously driven to move toward or away from the two racks on both sides by driving the gear 3121 to rotate. For example, the second drive assembly 500 may be a nut screw structure, which is synchronously driven to move toward or away from each other by driving the screw rod to rotate.

[0048] See also Figure 1 and Figure 2 In one embodiment, the molding device 1 further includes a support mechanism 20, which is spaced relative to the surface of the frame 100 provided with the side formwork assembly 200, and the support mechanism 20 and the two side formwork assemblies 200 and the two clamping plate assemblies 400 together form a pouring space. By providing the support mechanism 20, it is convenient to support the concrete in the pouring space, thereby facilitating the formation of the prefabricated guardrail 2. In other embodiments, the support mechanism 20 can also be omitted, and the frame 100 is provided at the bottom, and the frame 100 itself is used to support the poured concrete.

[0049] In this embodiment, the support mechanism 20 is located at the bottom, and then during demoulding, the side template assembly 200 rotates upward after moving the first demoulding distance, and the clamping plate assembly 400 also rotates upward, so that the prefabricated guardrail 2 is exposed on the support mechanism 20. In the subsequent steps, the formed prefabricated guardrail 2 can be removed from the support mechanism 20. During the demoulding process, the molding equipment 1 and the mold mechanism 10 do not need to be flipped. To avoid flipping the load-bearing mold mechanism 10, not only is it necessary to set up a flipping mechanism, but also the load requirements of the flipping mechanism are high. At the same time, during the flipping process, it is necessary to pay attention to whether the prefabricated guardrail 2 will fall out of the mold mechanism 10. In this application, the support mechanism 20 is set at the bottom, and the side template assembly 200 and the clamping plate assembly 400 are both rotated upward. There is no need to flip the mold mechanism 10, and the demoulding process is convenient and simple.

[0050] Specifically, the end of the prefabricated guardrail 2 with a larger cross-sectional dimension is located at the bottom, and the end with a smaller dimension is located at the top, so that the prefabricated guardrail 2 after demoulding can be stably set on the support mechanism 20, reducing the possibility of the prefabricated guardrail 2 overturning after demoulding.

[0051] like Figure 2 and Figure 4 As shown, in one embodiment, a partition 202 is provided on the support mechanism 20, and two side formwork assemblies 200 are respectively located on both sides of the partition 202, so that the partition 202 can divide the casting space into two forming cavities, so as to facilitate simultaneous casting to form two prefabricated guardrails 2. The two prefabricated guardrails 2 are arranged back to back to improve the molding efficiency of the prefabricated guardrail 2.

[0052] In one embodiment, a clamping assembly 203 is provided on the top of the partition 202, and the clamping assembly 203 is movable relative to the partition 202 and clamped on the side of the prefabricated guardrail 2 facing away from the partition 202. After the prefabricated guardrail 2 is formed and demoulded, the side of the prefabricated guardrail 2 facing away from the partition 202 is completely exposed to the outside. By providing the clamping assembly 203 to clamp the side of the prefabricated guardrail 2 facing away from the partition 202, the possibility of the prefabricated guardrail 2 turning over during transportation is reduced, thereby ensuring stability and safety during transportation.

[0053] Specifically, the clamping assembly 203 includes a clamping member 204 and a rotating driving member 205. The clamping member 204 includes a connecting portion 2041 and a clamping portion 2042 disposed on the connecting portion 2041. One end of the connecting portion 2041 away from the clamping portion 2042 is connected to the rotating driving member 205. The rotating driving member 205 is disposed on the partition 202. The rotating driving member 205 is used to drive the clamping member 204 to rotate so that the clamping portion 2042 can rotate to the side of the prefabricated guardrail 2 that is away from the partition 202. The prefabricated guardrail 2 is restricted on the partition 202 by the clamping portion 2042, thereby reducing the possibility of the prefabricated guardrail 2 moving.

[0054] In this embodiment, there are two clamping members 204 , and the rotating driving member 205 can drive the two clamping members 204 to rotate respectively in the directions of the two casting cavities, and can be respectively clamped on the prefabricated guardrails 2 located on both sides of the partition 202 .

[0055] The molding device 1 for the prefabricated guardrail 22 is convenient for demoulding the prefabricated guardrail 22, has high molding efficiency of the prefabricated guardrail 22, reduces damage to the prefabricated guardrail 22 during the demoulding process, and ensures the structural integrity of the prefabricated guardrail 22.
