[0001] The utility model relates to concrete prefabricated component molding equipment, in particular to a prefabricated component mold. Background Art

[0002] With the continuous optimization of bridge construction technology, the application of prefabricated bridge deck components is increasing, and the quality requirements for prefabricated bridge deck components are also getting higher and higher. At present, prefabricated bridge deck components are generally produced using steel molds, which have the advantages of high molding quality, not easy to deform, and reusable. Generally, the molds include a bottom mold, side molds on both sides of the bottom mold, and end molds on both ends of the bottom mold. The molds are connected by bolts. Since the prefabricated bridge deck components are deep E-shaped structures, in order to facilitate demoulding, the current method is mostly to increase the demoulding slope. However, increasing the demoulding slope will make the thickness of the legs of the deep E-shaped prefabricated bridge deck components thinner, which will affect the strength of the prefabricated bridge deck components and fail to meet the design requirements.

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Embodiment 1

[0036] Figures 1 to 5 An embodiment of the prefabricated component mold of the utility model is shown. The prefabricated component mold of this embodiment includes a base frame 1 and a bottom mold 2. The bottom mold 2 includes a main body 21 and leg parts 22 arranged on both sides of the main body 21 (which can be used to produce deep E-type prefabricated bridge deck components). The main body 21 is arranged on the base frame 1, and the base frame 1 provides support for the main body 21. The leg parts 22 can rotate relative to the main body 21 (the rotation angle is equivalent to the demoulding slope, so only a small rotation is required, such as 1° to 3°). The prefabricated component mold also includes a mold retracting mechanism 3 for driving the leg parts 22 to rotate. Among them, in addition to the deep E-type prefabricated bridge deck component, the prefabricated component can also be an L-shaped component or other types of prefabricated components. When it is an L-shaped component, the main body 21 is only provided with a leg part 22 on one side.

[0037] In the prefabricated component mold of this embodiment, the leg parts 22 on both sides of the bottom mold 2 and the main body 21 between the two leg parts 22 are no longer a rigid whole, but can rotate relatively, and the leg parts 22 can be driven to rotate by the mold closing mechanism 3. When closing the mold, the leg parts 22 on both sides rotate toward the middle to achieve the purpose of shrinking and closing, which is conducive to smooth demoulding and improved production efficiency. There is no need to increase the demoulding slope of the bottom mold 2 to avoid affecting the strength of the prefabricated component 6.

[0038] Furthermore, in this embodiment, the working surface 23 of the main body 21 is connected to the working surface 23 of the leg 22, and there is a gap between the reinforcing ribs 24 of the main body 21 and the reinforcing ribs 24 of the leg 22. Preferably, the working surfaces 23 of the main body 21 and the leg 22 are formed of a whole steel plate to avoid the generation of seams. Of course, in other embodiments, the working surfaces 23 of the two can also be split structures and connected as a whole; the reinforcing ribs 24 can improve the strength of the working surface 23 to avoid deformation of the working surface 23 after being squeezed by concrete, and the gap between the reinforcing ribs 24 of the main body 21 and the reinforcing ribs 24 of the leg 22 can reduce resistance, facilitate the rotation of the leg 22 relative to the main body 21, and the structure is simple and reliable.

[0039] Furthermore, in this embodiment, side molds 4 are provided on both sides of the bottom mold 2, and the side molds 4 are hinged to the base frame 1. The mold retracting mechanism 3 includes a linkage rod 31, one end of the linkage rod 31 is connected to the side mold 4, and the other end of the linkage rod 31 is connected to the leg portion 22. When the side mold 4 is turned outward to open the mold, the leg portion 22 on the same side can be driven to rotate synchronously toward the middle through the linkage rod 31, so as to achieve the contraction of the leg portion 22, killing two birds with one stone, improving the efficiency of demolding, and having a simple and effective structure. When the side mold 4 is turned inward to close the mold, the leg portion 22 on the same side can also be driven to expand and reset synchronously outward through the linkage rod 31, so as to prepare for the casting of the next prefabricated component 6. Of course, in other embodiments, power components such as oil cylinders and air cylinders can also be set on the base frame 1 to drive the leg portion 22 to rotate, which can also achieve the purpose, but it will cause the mold structure to become complicated and the cost to be higher.

[0040] As a preferred embodiment, one end of the linkage rod 31 is hinged to the side mold 4, and the other end of the linkage rod 31 is provided with a linkage hole 32. The leg portion 22 is provided with a connecting pin 25, and the connecting pin 25 is inserted into the linkage hole 32 and has a gap with the linkage hole 32, which can allow the linkage rod 31 and the leg portion 22 to move relative to each other, avoiding the side mold 4 from getting stuck during the opening and closing process, and the structure is simple and reasonable. Among them, the linkage hole 32 is preferably a waist-shaped hole, and of course in other embodiments it can also be a round hole with an inner diameter larger than the diameter of the connecting pin 25.

[0041] Embodiment 2

[0042] Figures 6 to 9 Another embodiment of the prefabricated component mold of the utility model is shown. The structure of the prefabricated component mold of this embodiment is basically the same as that of the first embodiment, except that:

[0043] In this embodiment, the bottom mold 2 includes two split parts of a few shapes, and the mold collection mechanism 3 is connected between the leg parts 22 on both sides of the split parts. The bottom mold 2 is split into two split parts of a few shapes, and the distance between the leg parts 22 on both sides of the split parts is reduced compared with the first embodiment, so it is convenient for the mold collection mechanism 3 to simultaneously connect the leg parts 22 on both sides. A total of four parts of the bottom mold 2 can be rotated to disengage from the prefabricated component 6, so it is easier to take out the prefabricated component 6. Of course, in other embodiments, as the size of the bottom mold 2 increases, the number of split parts can also be further adjusted.

[0044] Furthermore, in this embodiment, the mold closing mechanism 3 includes a screw rod 33 and a plurality of nut seats 34 spaced apart along the length direction of the screw rod 33, and a connecting rod 35 is hinged on the nut seat 34, and the connecting rod 35 is hinged with the leg portion 22. When the screw rod 33 rotates, the nut seat 34 thereon moves along the screw rod 33, and then pulls the leg portions 22 on both sides to rotate and move closer to the middle through the connecting rod 35. Conversely, when the screw rod 33 rotates in the opposite direction, the nut seat 34 moves in the opposite direction along the screw rod 33, and pushes the leg portions 22 on both sides to rotate and spread out to both sides through the connecting rod 35, and the structure is reasonable and effective.

[0045] As a preferred embodiment, the mold retracting mechanism 3 also includes a demolding drive member (not shown in the figure, for example, it can be a motor, a hydraulic motor, etc.) for driving the screw rod 33 to rotate, which can realize the automatic rotation and contraction of the leg part 22, making it more convenient to use.

[0046] Embodiment 3

[0047] Figures 10 to 12 Another embodiment of the prefabricated component mold of the utility model is shown. The structure of the prefabricated component mold of this embodiment is basically the same as that of the second embodiment, except that:

[0048] In this embodiment, the mold closing mechanism 3 includes a demoulding rod 36 that can reciprocate in the axial direction and a plurality of connection seats 37 that are spaced apart along the length direction of the demoulding rod 36. A connecting rod 35 is hinged on the connection seat 37, and the connecting rod 35 is hinged with the leg portion 22. When the demoulding rod 36 moves, the connection seat 37 thereon is driven to move, and then the leg portions 22 on both sides are pulled to rotate and move closer to the middle through the connecting rod 35. Conversely, when the demoulding rod 36 moves in the opposite direction, the connection seat 37 thereon is driven to move in the opposite direction, and the leg portions 22 on both sides are pushed to rotate and spread out to both sides through the connecting rod 35. The structure is reasonable and effective.

[0049] Furthermore, in this embodiment, end molds 5 are provided at both ends of the bottom mold 2, the end molds 5 are hinged to the bottom frame 1, and one end of the demoulding rod 36 is hinged to the end mold 5. When the end mold 5 is turned outward to open the mold, the demoulding rod 36 can drive the leg part 22 to rotate synchronously toward the middle to achieve the contraction of the leg part 22, killing two birds with one stone, improving the demoulding efficiency, and having a simple and effective structure. When the end mold 5 is turned inward to close the mold, the demoulding rod 36 can also drive the leg part 22 to expand and reset synchronously outward to prepare for the casting of the next prefabricated component 6.

[0050] In this embodiment, the mold retracting mechanism 3 also includes a demolding drive member (not shown in the figure, for example, it can be an oil cylinder, an air cylinder, etc.) for driving the demolding rod 36 to move back and forth, which can realize the automatic rotation and contraction of the leg part 22, making it more convenient to use.
