Abstract
Description
Technical Field
[0001] This utility model relates to the field of pole production technology, specifically to pole production equipment with quick mold change capability. Background Technology
[0002] Cement poles are supporting structures used for power transmission and wire suspension. They are typically made of concrete, possessing high strength and durability, capable of withstanding the weight of the wires and wind forces. Cement poles are widely used in power transmission and wiring systems. The production process of cement poles involves first placing a steel reinforcement frame inside a mold and then pouring concrete. After the concrete is poured, the mold is transferred by crane to a centrifuge for high-speed centrifugal molding to ensure the pole's density and strength. However, most cement pole production molds on the market currently have simple structures and are cumbersome to operate. When closing the mold, workers must use a wrench to rotate multiple locking bolts along the mold's edge one by one to ensure a tight connection. This process is time-consuming, and all locking bolts must be manually removed during demolding, significantly reducing production efficiency.
[0003] Patent CN221850642U discloses a cement pole production mold, including an upper mold and a lower mold that cooperate with each other. The upper mold has a first mold-opening assembly symmetrically arranged on both sides, and the lower mold has a second mold-opening assembly symmetrically arranged on both sides, cooperating with the first mold-opening assembly. The first mold-opening assembly includes a housing fixed to both sides of the upper mold, a rotating rod rotatably disposed inside the housing, a worm gear equidistantly embedded on the rotating rod, a worm wheel meshing with one side of the worm gear and rotatably connected to the upper mold, and a bolt slidably disposed inside the worm wheel and rotating with it. The edges of both the upper and lower molds have threaded holes corresponding to the bolts. This invention can automatically connect and fix the upper and lower molds without requiring manual tightening of bolts, saving time and effort and improving production efficiency.
[0004] The aforementioned existing technology achieves automatic connection and fixation through mold opening and closing assembly one and mold opening and closing assembly two, but its structure is still complex. During the docking process, the meshing transmission between the worm gear and multiple worm wheels requires precise matching, and further matching of bolts and screw holes is also required, resulting in numerous transmission structures. In addition, the electric push rod is used to position the clamping plate, and the motor drives the worm gear to rotate, involving a large number of transmission structures. This not only increases the manufacturing cost of the equipment but also leads to potential wear and failure risks, thereby affecting the long-term performance and ease of maintenance of the equipment. In view of this, we propose a pole production equipment with quick mold change capability. Utility Model Content
[0005] The purpose of this invention is to provide a pole production equipment with quick mold change capability to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A quick-change mold pole production equipment includes an upper mold and a lower mold. The outer wall of the upper mold is provided with multiple sets of equidistantly arranged semi-circular first reinforcing plates to enhance the structural strength and stability of the mold and ensure that the mold will not deform during operation. Each set consists of multiple equidistantly arranged semi-circular first reinforcing plates. A semi-circular first roller is provided between two adjacent sets of semi-circular first reinforcing plates. Multiple semi-circular first reinforcing plates and multiple semi-circular first rollers are connected to two strip-shaped fixing plates arranged symmetrically front and back. The bottom of the strip-shaped fixing plates is provided with multiple rectangular docking blocks arranged equidistantly from left to right for docking with locking components.
[0008] The outer wall of the lower mold is provided with multiple sets of equidistantly arranged semi-circular second reinforcing plates. By enhancing the structural strength and stability of the mold, it ensures that the mold will not deform during operation. Each set consists of multiple equidistantly arranged semi-circular second reinforcing plates. A semi-circular second roller is provided between two adjacent sets of semi-circular second reinforcing plates. The semi-circular first roller and the semi-circular second roller are combined to form a complete roller. When high-speed centrifugal molding is performed on the centrifuge, the roller abuts against the drive wheel, allowing the mold to rotate smoothly. Multiple semi-circular second reinforcing plates and multiple semi-circular second rollers are connected to two locking components that are symmetrically arranged front and back. By fixing the upper mold and the lower mold, it is ensured that the molds are tightly connected during the production process.
[0009] The locking assembly includes a rectangular horizontal plate. An inverted T-shaped movable groove is provided on the left side of the rectangular horizontal plate to accommodate and guide the movement of the slider, ensuring the stability of the locking and releasing operation. A threaded groove is provided on the right side of the inner wall of the inverted T-shaped movable groove near the bottom, which, in cooperation with the screw, enables precise movement of the slider.
[0010] The threaded groove is threadedly connected to a screw rod, and the left end of the screw rod is provided with a connecting rod for driving the slider to move, thereby realizing the locking or unlocking operation of the mold. The connecting rod drives the screw rod to rotate. When the screw rod moves into the threaded groove, the connecting rod drives multiple sliders to move to the right, thereby inserting the rectangular block into the rectangular insertion hole, realizing the docking of the strip fixing plate and the locking component, thereby closing the upper mold and the lower mold. When the screw rod moves out of the threaded groove to the left, the connecting rod drives multiple sliders to move to the left, causing the rectangular block to move out of the rectangular insertion hole, releasing the positioning of the rectangular docking block, allowing the upper mold to move upward, thereby realizing the separation of the upper mold and the lower mold.
[0011] The outer wall of the connecting rod is rotatably connected to multiple sliders arranged equidistantly on the left and right. The top of the slider is provided with a rectangular protrusion, and the top right side of the rectangular protrusion is provided with a rectangular insert. The top of the rectangular horizontal plate is provided with a rectangular docking groove for the rectangular docking block to be inserted, which enhances the accuracy and firmness of the docking. The left side of the rectangular docking block is provided with a rectangular insertion hole for the rectangular insert to be inserted, which locks the mold through cooperation.
[0012] Preferably, a first reinforcing strip is provided between two adjacent semi-circular first reinforcing plates to enhance the rigidity of the mold structure and improve the service life of the mold. A first reinforcing strip is provided between adjacent semi-circular first reinforcing plates and semi-circular first rollers to further enhance the overall strength.
[0013] Preferably, the bottom of both the semi-circular first reinforcing plate and the semi-circular first roller is provided with a first U-shaped mounting groove, and the outer side of the strip-shaped fixing plate is welded into the first U-shaped mounting groove to improve the connection reliability of the mold.
[0014] Preferably, a second reinforcing strip is provided between two adjacent semi-circular second reinforcing plates to improve the stability of the overall mold structure, and a second reinforcing strip is provided between adjacent semi-circular second reinforcing plates and semi-circular second rollers to enhance the mold's compressive strength.
[0015] Preferably, the top of both the semi-circular second reinforcing plate and the semi-circular second roller is provided with a second U-shaped mounting groove, and the outer side of the rectangular horizontal plate is welded into the second U-shaped mounting groove to improve the overall rigidity of the mold.
[0016] Preferably, the outer wall of the connecting rod is provided with a first limiting ring at the position on the left and right sides of the slider to ensure that the slider moves left and right with the connecting rod, and the slider is slidably connected in the inverted T-shaped movable groove.
[0017] Preferably, an inverted T-shaped plug is rotatably connected to the outer wall of the connecting rod near the left end. A second limiting ring is provided on both the outer wall of the connecting rod and on both sides of the inverted T-shaped plug to ensure that the inverted T-shaped plug moves left and right with the connecting rod. The inverted T-shaped plug is located at the left end inside the inverted T-shaped movable groove, which plays a role in stabilizing the rotation of the connecting rod and preventing the left end of the connecting rod from bending.
[0018] Preferably, the left end of the connecting rod is equipped with a handwheel, which facilitates operation by the staff and allows for quick locking and unlocking of the mold.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. This quick-change mold pole production equipment achieves rapid locking and unlocking of the mold through the cooperation of locking components and rectangular docking blocks.

[0035] Please see Figures 1-9 This utility model provides a technical solution:
[0036] The pole production equipment with quick-change molds includes an upper mold 1 and a lower mold 2. The outer wall of the upper mold 1 is provided with multiple sets of equidistant semi-circular first reinforcing plates 10. By enhancing the structural strength and stability of the mold, it is ensured that the mold will not deform during operation. Each set consists of multiple equidistant semi-circular first reinforcing plates 10. A semi-circular first roller 11 is provided between two adjacent sets of semi-circular first reinforcing plates 10. Multiple semi-circular first reinforcing plates 10 and multiple semi-circular first rollers 11 are connected to two strip-shaped fixing plates 3 arranged symmetrically front and back. The bottom of the strip-shaped fixing plates 3 is provided with multiple rectangular docking blocks 30 arranged equidistantly from left to right for docking with the locking component 4.
[0037] The outer wall of the lower mold 2 is provided with multiple sets of equidistantly arranged semi-circular second reinforcing plates 20. By enhancing the structural strength and stability of the mold, it is ensured that the mold will not deform during operation. Each set consists of multiple equidistantly arranged semi-circular second reinforcing plates 20. A semi-circular second roller 21 is provided between two adjacent sets of semi-circular second reinforcing plates 20. The semi-circular first roller 11 and the semi-circular second roller 21 are combined to form a complete roller. When high-speed centrifugal molding is performed on the centrifuge, the roller abuts against the drive wheel, so that the mold can rotate smoothly. Multiple semi-circular second reinforcing plates 20 and multiple semi-circular second rollers 21 are connected to two locking components 4 arranged symmetrically in front and behind. By fixing the upper mold 1 and the lower mold 2, it is ensured that the molds are tightly connected during the production process.
[0038] The locking assembly 4 includes a rectangular horizontal plate 40. An inverted T-shaped movable groove 400 is provided on the left side of the rectangular horizontal plate 40 to accommodate and guide the movement of the slider 42, ensuring the stability of the locking and releasing operation. A threaded groove 402 is provided on the right side of the inner wall of the inverted T-shaped movable groove 400 near the bottom, which, in cooperation with the screw 44, enables the precise movement of the slider 42.
[0039] The threaded groove 402 is threadedly connected to a screw 44. The left end of the screw 44 is provided with a connecting rod 41, which is used to drive the slider 42 to move, thereby realizing the locking or unlocking operation of the mold. The connecting rod 41 drives the screw 44 to rotate. When the screw 44 moves into the threaded groove 402, the connecting rod 41 drives multiple sliders 42 to move to the right, thereby allowing the rectangular insert 421 to be inserted into the rectangular insertion hole 300, realizing the docking of the strip fixing plate 3 and the locking component 4, thereby closing the upper mold 1 and the lower mold 2. When the screw 44 moves out to the left from the threaded groove 402, the connecting rod 41 drives multiple sliders 42 to move to the left, causing the rectangular insert 421 to move out from the rectangular insertion hole 300, releasing the positioning of the rectangular docking block 30, allowing the upper mold 1 to move upward, thereby realizing the separation of the upper mold 1 and the lower mold 2.
[0040] The outer wall of the connecting rod 41 is rotatably connected to multiple sliders 42 arranged equidistantly on the left and right. The top of the slider 42 is provided with a rectangular protrusion 420, and the top right side of the rectangular protrusion 420 is provided with a rectangular insert 421. The top of the rectangular horizontal plate 40 is provided with a rectangular docking groove 401 for the rectangular docking block 30 to be inserted, which enhances the docking accuracy and firmness. The left side of the rectangular docking block 30 is provided with a rectangular insertion hole 300 for the rectangular insert 421 to be inserted, which locks the mold through cooperation.
[0041] In this embodiment, a first reinforcing strip 12 is provided between two adjacent semi-circular first reinforcing plates 10 to enhance the rigidity of the mold structure and improve the service life of the mold. A first reinforcing strip 12 is provided between adjacent semi-circular first reinforcing plates 10 and semi-circular first rollers 11 to further enhance the overall strength.
[0042] Specifically, the bottom of the semi-circular first reinforcing plate 10 and the semi-circular first roller 11 are both provided with a first U-shaped mounting groove 13, and the outer side of the strip-shaped fixing plate 3 is welded into the first U-shaped mounting groove 13 to improve the connection reliability of the mold.
[0043] Furthermore, a second reinforcing strip 22 is provided between two adjacent semi-circular second reinforcing plates 20 to improve the stability of the overall mold structure. A second reinforcing strip 22 is provided between adjacent semi-circular second reinforcing plates 20 and semi-circular second rollers 21 to enhance the mold's compressive strength.
[0044] Furthermore, the top of both the semi-circular second reinforcing plate 20 and the semi-circular second roller 21 is provided with a second U-shaped mounting groove 23, and the outer side of the rectangular horizontal plate 40 is welded into the second U-shaped mounting groove 23 to improve the overall rigidity of the mold.
[0045] Furthermore, the outer wall of the connecting rod 41 is provided with first limiting rings 410 on both sides of the slider 42 to ensure that the slider 42 moves left and right with the connecting rod 41 and is slidably connected in the inverted T-shaped movable groove 400.
[0046] Furthermore, an inverted T-shaped block 43 is rotatably connected to the outer wall of the connecting rod 41 near the left end. A second limiting ring 411 is provided on both the outer wall of the connecting rod 41 and on both the left and right sides of the inverted T-shaped block 43 to ensure that the inverted T-shaped block 43 moves left and right with the connecting rod 41. The inverted T-shaped block 43 is located at the left end inside the inverted T-shaped movable groove 400, which plays a role in stabilizing the rotation of the connecting rod 41 and preventing the left end of the connecting rod 41 from bending.
[0047] Furthermore, a handwheel 45 is provided at the left end of the connecting rod 41, which facilitates operation by staff and allows for quick locking and unlocking of the mold.
[0048] In this embodiment of the quick-change mold pole production equipment, the equipment is first adjusted to the initial state, that is, the upper mold 1 and the lower mold 2 are separated. The operator places the steel reinforcement skeleton inside the lower mold 2, and then fixes and adjusts the skeleton as needed to ensure its stability. After the steel reinforcement skeleton is placed, the upper mold 1 is moved smoothly to the top of the lower mold 2, and then moved downward so that multiple rectangular docking blocks 30 are inserted into multiple rectangular docking slots 401 respectively, so that the two are aligned. At this time, the operator rotates the handwheel 45, and the rotation of the handwheel 45 drives the connecting rod 41 to rotate. The connecting rod 41 further drives the screw 44 to move inward along the threaded groove 402, and then pushes the slider 42 to slide to the right, so that the rectangular insert 421 is precisely docked with the rectangular insert 300. With the synchronous movement of multiple sliders 42, the strip fixing plate 3 and the locking component 4 are docked, and the upper mold 1 and the lower mold 2 achieve a firm mold closing state.
[0049] After the mold is closed, the operator begins to pour concrete into the mold. After the concrete is grouted, the operator uses a crane or other transport device to transfer the closed mold to a centrifuge. Under the action of the centrifuge, the high-speed rotation causes the rollers (composed of a semi-circular first roller 11 and a semi-circular second roller 21) to come into contact with the centrifuge drive wheel, thereby driving the entire mold to rotate at high speed. Centrifugal force is used to distribute the concrete evenly and further compact it, ensuring the structural strength and quality of the pole.
[0050] After the centrifugal molding process is completed, the mold needs to be demolded. At this time, the operator rotates the handwheel 45 again. The reverse rotation of the handwheel 45 drives the connecting rod 41 and the screw 44 to move in the opposite direction. As the screw 44 exits from the threaded groove 402, the slider 42 slides to the left, the rectangular insert 421 separates from the rectangular insert 300, and the connection between the strip fixing plate 3 and the locking component 4 is released. At this time, the upper mold 1 can be lifted to the open state, thereby separating from the lower mold 2. The operator then takes out the formed cement pole from the lower mold 2 and cleans and maintains the mold to prepare for the next production.
[0051] The entire process significantly improves production efficiency by simplifying mold closing and opening operations. A reliable locking mechanism and convenient manual operation ensure the accuracy and stability of mold docking, while reducing the labor intensity of operators and improving the ease of use and production efficiency of the equipment.
[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
