Description

Technical Field

[0001] This invention relates to the field of demolding in cement pole manufacturing, specifically to an automated demolding device for cement pole manufacturing. Background Technology

[0002] Cement poles, as core components in infrastructure construction such as power transmission and communication networks, are widely used in urban and rural construction and transportation networks due to their advantages of stable structure, high compressive strength, and long service life. Their manufacturing quality directly affects the operational stability of power and communication systems. The molding and processing of cement poles falls under the category of molding processes involving cement-based material mixtures. The core production process includes key steps such as reinforcing cage erection, mold closing and positioning, concrete pouring, centrifugal curing, and mold demolding. Among these, the mold closing accuracy, sealing reliability, and positioning stability are fundamental to ensuring the molding quality of cement poles. Currently, in the existing cement pole manufacturing process, the mold closing, sealing, and limiting operations that are connected to the demolding process are mostly completed manually or with simple mechanical assistance. This makes it easy for the mold to deviate and jam during sliding, and the clamping force on the mold is unevenly distributed during mold closing, which can easily lead to mold misalignment and local deformation. This not only causes quality defects such as uneven wall thickness and axial misalignment in the cement pole after molding, but also increases the difficulty of subsequent demolding operations due to mold deformation, and may even scratch the surface of the pole during demolding, reducing the product qualification rate. In addition, manual operation requires multiple workers to work together to complete the mold position adjustment, bolt tightening, and external clamping processes. This is not only labor-intensive and inefficient, but also prone to human error due to differences in experience and physical strength of the operators, resulting in different batches. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an automated demolding device for cement pole manufacturing, which solves the problem that the mold closing of cement poles relies on manual operation or simple mechanical assistance.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An automated demolding device for cement pole manufacturing includes a main body plate. A fixing frame is provided in the middle of the upper part of the main body plate. A first mold and a second mold are provided on the upper part of the fixing frame. Stabilizing seats are provided on both sides of the first mold and the second mold. A stop frame is provided on the side of each of the two stabilizing seats away from the first mold. A threaded block is provided at the front end of the lower part of the stabilizing seat. A slider is provided at the rear end of the lower part of the stabilizing seat. A rotating groove is provided at the front end of the upper part of the main body plate. Sliding grooves are provided on both sides of the rear end of the upper part of the main body plate. A cylinder is provided at the middle of the front and rear ends of the fixed frame. Limit plates are provided at the front and rear ends of the upper sides of the main body plate. Positioning plates are provided at the front and rear ends of the upper sides of the main body plate near the corresponding limit plates. Movable frames are provided inside the two front positioning plates and the two rear positioning plates. Fastening blocks are provided on both sides of the movable frames near the first mold. A protective shell is provided at the middle of the front end of the main body plate. A drive motor is provided inside the protective shell. A worm gear is provided inside the front end of the main body plate. A bidirectional threaded rod is provided inside the rotating groove. A worm wheel is provided at the middle of the bidirectional threaded rod. The above technical solution enables the integrated installation of components such as mold closing drive, limit sealing, and power transmission. The components work together to form a linkage operation system, providing a stable structural support for mold closing, sealing and limiting, and subsequent demolding. At the same time, it realizes automated linkage control of each process, reduces the need for manual intervention, and improves the overall stability and automation level of the device.

[0005] Furthermore, the outer walls on both sides of the movable frame slide against the inner walls of the corresponding two positioning plates, the lower ends of the fixed frame are fixed to the corresponding positions on the upper part of the main body plate, the middle parts of the front and rear ends of the fixed frame are fixed to one end of the corresponding cylinder, and the output ends of the two cylinders are fixed to the middle of one end of the corresponding movable frame. The above technical solution enables the movable frame to slide smoothly along the positioning plate, avoiding deviation or jamming during the movement of the movable frame. The rigid connection between the cylinder and the fixed frame and the movable frame provides a stable and continuous linear driving force for the movable frame, ensuring that the movable frame drives the fastening block and the mold to make precise mold closing linear movements, thereby improving the smoothness and accuracy of the mold closing action.

[0006] Furthermore, the ends of the two fastening blocks near the corresponding movable frame are fixedly connected to the corresponding sides of the movable frame, the ends of the two front fastening blocks away from the corresponding movable frame are adapted and fixed to the corresponding sides of the outer wall of the second mold, the ends of the two rear fastening blocks away from the corresponding movable frame are adapted and fixed to the corresponding sides of the outer wall of the first mold, and the two limiting plates limit the position of the corresponding movable frame. Through the above technical solution, the fastening block enables precise linkage between the movable frame and the first and second molds, ensuring that the two molds move closer together synchronously under the drive of the cylinder to achieve precise mold closing, ensuring the coaxiality of the molds during mold closing, and the limiting plate can effectively limit the maximum movement stroke of the movable frame to prevent excessive mold closing from causing mold extrusion deformation or component damage, thus accurately ensuring the accuracy of the mold closing position.

[0007] Furthermore, the outer wall of the worm rotates at the middle of the inner wall of the front end of the main body plate, the protective shell is fixed to the middle of the outer wall of the front end of the main body plate by bolts, the inside of the protective shell is fixed to the outside of the drive motor, the output end of the drive motor is fixed to the front end of the worm, the inner walls on both sides of the rotating groove are rotatably connected to the two sides of the bidirectional threaded rod, and the inner wall of the worm wheel is fixed to the middle of the body of the bidirectional threaded rod. Through the above technical solutions, stable power transmission from the drive motor to the worm gear and bidirectional threaded rod is achieved. Each rotating connection structure ensures the smooth rotation of the transmission components, reduces mechanical wear during transmission, and the protective shell effectively protects the drive motor, isolating it from impurities such as concrete slurry and dust during the production process, preventing the motor from being contaminated and damaged, and extending the service life of the drive motor.

[0008] Furthermore, the rear end of the worm gear meshes with the outer wall of the worm wheel, both sides of the bidirectional threaded rod body are threadedly connected to the inner walls of the two threaded blocks, the outer walls of the two threaded blocks slide with the sides corresponding to the rotating groove, and the outer walls of the two sliders slide with the inner walls of the sliding groove. The above technical solution utilizes the meshing transmission of worm gears to convert the rotational power of the drive motor into the rotational power of the bidirectional threaded rod, and then converts it into the linear motion of the threaded blocks on both sides through threaded transmission, thereby realizing the synchronous movement of the two stabilizers in opposite directions or in opposite directions. The dual sliding guidance of the threaded blocks and the rotating groove, and the slider and the groove, ensures the synchronicity, straightness and stability of the stabilizer movement, and improves the accuracy of the mold's limiting and sealing action.

[0009] Furthermore, the front end of the lower part of the stabilizer is fixed to the upper end of the corresponding threaded block, the rear end of the lower part of the stabilizer is fixed to the upper end of the corresponding slider, and the center of the stabilizer away from the main body plate is fixed to one side of the corresponding abutment. Both abutments are adapted to the grooves on both sides of the first mold and the second mold. Through the above technical solutions, a firm connection is achieved between the stabilizing seat and the transmission and guiding components, ensuring the effective transmission of power and guiding force. This ensures that the stabilizing seat moves synchronously and precisely with the threaded block and the slider. The precise fit between the support frame and the grooves on both sides of the mold allows the support frame to be embedded in the mold groove, forming a reliable mechanical limit and seal for the mold after mold closing. This prevents the mold from loosening or shifting during the pouring and curing process, providing a solid structural foundation for preventing leakage during pouring.

[0010] Furthermore, both the front and rear limiting plates are fixed to the corresponding positions on the upper part of the main body plate, and both the front and rear positioning plates are fixed to the corresponding positions on the upper part of the main body plate. The above technical solutions provide a stable and reliable guiding and limiting foundation for the movement of the movable frame. The fixed connection method ensures that the limiting plate and positioning plate do not loosen or shift during the operation of the device, ensuring that their guiding and limiting functions on the movable frame are continuously effective, avoiding the impact of loose parts on the mold closing accuracy, and further improving the overall structural robustness and operational stability of the device.

[0011] Furthermore, the four fastening blocks have an arc-shaped contact surface on the side that contacts the first mold and the second mold, and the arc-shaped contact surface is fixed to the outer wall of the first mold and the second mold in an arc shape; By using the above technical solutions, the contact area between the fastening block and the outer wall of the mold is increased, so that the clamping force of the fastening block on the mold is evenly distributed on the outer wall of the mold, avoiding mold deformation and misalignment caused by uneven local force. At the same time, the fit between the fastening block and the outer wall of the mold is improved, the sealing effect of the mold splicing surface after mold closing is enhanced, and the leakage path of concrete slurry is further blocked, reducing the problem of pouring leakage.

[0012] This invention provides an automated demolding device for cement pole fabrication. It has the following advantages: 1. This invention provides an automated demolding device for cement pole manufacturing. A cylinder drives a movable frame to slide along a positioning plate, and a fastening block with an arc-shaped contact surface achieves coaxial mold closing between the first and second molds. This increases the mold contact area, avoids misalignment caused by uneven local stress, and further ensures mold closing accuracy through the bidirectional guiding constraint of the limiting plate, laying a solid foundation for the uniformity of wall thickness and the straightness of the axis of the cement pole after molding. After mold closing, the drive motor drives the bidirectional threaded rod to rotate smoothly through the precise meshing of the worm gear and worm wheel. Combined with the guiding action of the slider and the groove, the two stabilizing seats move synchronously towards each other, allowing the support frame to accurately embed into the pre-set grooves on both sides of the mold, forming a reliable mechanical sealing barrier. Simultaneously, the cylinder continuously outputs stable pressure, applying a continuous pre-tightening force to the mold through the movable frame and the fastening block, forming a double-sealed protective structure. This completely blocks the path of concrete slurry leakage from the mold gaps, effectively avoiding process defects such as honeycomb, pitting, and chipped edges on the pole surface.

[0013] 2. This invention provides an automated demolding device for cement pole manufacturing. The device's automated control enables unmanned operation of the entire process, from mold closing to sealing and limiting, eliminating the need for manual adjustment of the mold position, tightening of bolts, or installation of seals. This not only eliminates the heavy physical labor of traditional manual operation but also avoids the impact of human error on work quality, ensuring a high degree of consistency in mold closing accuracy and sealing effect across different batches. The overall structure is rationally laid out and the stress is balanced. Key stress-bearing components are reinforced to have excellent compressive and deformation resistance. The transmission components are encapsulated and protected to isolate impurities and reduce component wear, significantly extending the equipment's service life. In automated control mode, the mold closing pressure and sealing force ensure consistent molding quality for each cement pole, reducing the risk of product scrap and minimizing concrete slurry waste. It also avoids safety hazards such as mold tipping and pinching that may occur during manual operation, providing strong support for enterprises to reduce production costs, improve production qualification rates, and enhance market competitiveness.

A fixing frame 8 is provided at the middle of the upper end of the main body plate 1. A first mold 2 and a second mold 21 are provided on the upper part of the fixing frame 8.

Limit plates 4 are provided at the front and rear ends of both sides of the upper part of the main body plate 1. A fixed... The positioning plate 41, the two front positioning plates 41 and the two rear positioning plates 41 are all equipped with movable frames 5. The movable frames 5 are equipped with fastening blocks 51 on both sides near the first mold 2. The protective shell 6 is provided in the middle of the front end of the main body plate 1. The drive motor 62 is provided inside the protective shell 6. The worm gear 61 is provided inside the front end of the main body plate 1. The double-threaded rod 64 is provided inside the rotating groove 11. The worm wheel 63 is provided in the middle of the double-threaded rod 64. The integrated installation of the mold closing drive, limit sealing and power transmission components is realized. The components work together to form a linkage operation system, which provides a stable structural support for mold closing, sealing and limiting and subsequent demolding. At the same time, it realizes the automated linkage control of each process, reduces the need for manual intervention and improves the overall stability and automation level of the device.

[0018] Both outer walls of the movable frame 5 slide against the inner walls of the corresponding two positioning plates 41. The lower ends of the fixed frames 8 are fixed to the corresponding positions on the upper part of the main body plate 1. The middle of the front and rear ends of the fixed frames 8 are fixed to one end of the corresponding cylinder 7. The output ends of the two cylinders 7 are fixed to the middle of one end of the corresponding movable frame 5. This enables the movable frame 5 to slide smoothly along the positioning plates 41, avoiding deviation or jamming during the movement of the movable frame 5. The rigid connection between the cylinder 7, the fixed frame 8, and the movable frame 5 provides a stable and continuous linear driving force for the movable frame 5, ensuring that the movable frame 5 drives the fastening block 51 and the mold to make precise mold closing linear movements, improving the smoothness and accuracy of the mold closing action.

[0019] Two fastening blocks 51 are fixedly connected to the corresponding sides of the movable frame 5 at their ends near the corresponding ends of the movable frame 5. The ends of the two front fastening blocks 51 away from the corresponding movable frame 5 are adapted and fixed to the corresponding sides of the outer wall of the second mold 21. The ends of the two rear fastening blocks 51 away from the corresponding movable frame 5 are adapted and fixed to the corresponding sides of the outer wall of the first mold 2. The two limiting plates 4 limit the position of the corresponding end of the movable frame 5. The fastening blocks 51 realize the precise linkage between the movable frame 5 and the first mold 2 and the second mold 21, ensuring that the two molds move closer together synchronously under the drive of the cylinder 7 to achieve precise mold closing, ensuring the coaxiality of the mold during mold closing. The limiting plates 4 can effectively limit the maximum movement stroke of the movable frame 5, preventing excessive mold closing from causing mold extrusion deformation or component damage, and accurately ensuring the accuracy of the mold closing position.

[0020] The outer wall of the worm 61 rotates with the middle of the inner wall of the front end of the main body plate 1. The protective shell 6 is fixed to the middle of the outer wall of the front end of the main body plate 1 by bolts. The inside of the protective shell 6 is fixed to the outside of the drive motor 62. The output end of the drive motor 62 is fixed to the front end of the worm 61. The inner walls on both sides of the rotating groove 11 are rotatably connected to the two sides of the bidirectional threaded rod 64. The inner wall of the worm wheel 63 is fixed to the middle of the body of the bidirectional threaded rod 64. This achieves stable power transmission from the drive motor 62 to the worm 61 and the bidirectional threaded rod 64. Each rotating connection structure ensures the smooth rotation of the transmission components and reduces mechanical wear during transmission. The protective shell 6 can effectively protect the drive motor 62, isolate it from impurities such as concrete slurry and dust during the production process, prevent the motor from being contaminated and damaged, and extend the service life of the drive motor 62.

[0021] The rear ends of the worm 61 mesh with the outer wall of the worm wheel 63. Both sides of the bidirectional threaded rod 64 are threadedly connected to the inner walls of the two threaded blocks 32. The outer walls of the two threaded blocks 32 slide with the corresponding sides of the rotating groove 11. The outer walls of the two sliders 33 slide with the corresponding inner walls of the sliding groove 12. The rotational power of the drive motor 62 is converted into the rotational power of the bidirectional threaded rod 64 by the meshing transmission of the worm 61 and the worm wheel 63. Then, it is converted into the linear motion of the two threaded blocks 32 through the threaded transmission, so as to realize the synchronous opposite or opposite motion of the two stable seats 3. The double sliding guide between the threaded blocks 32 and the rotating groove 11, and between the sliders 33 and the sliding groove 12, ensures the synchronicity, straightness and stability of the movement of the stable seats 3, and improves the accuracy of the mold limiting and sealing action.

[0022] The front end of the lower part of the stabilizing seat 3 is fixed to the upper end of the corresponding threaded block 32, and the rear end of the lower part of the stabilizing seat 3 is fixed to the upper end of the corresponding slider 33. The center of the stabilizing seat 3 away from the main body plate 1 is fixed to one side of the corresponding abutment 31. Both abutments 31 are adapted to the grooves on both sides of the first mold 2 and the second mold 21, so as to realize the firm connection between the stabilizing seat 3 and the transmission component and the guide component, ensure the effective transmission of power and guiding force, and ensure that the stabilizing seat 3 moves synchronously and accurately with the threaded block 32 and the slider 33. The precise adaptation of the abutment 31 to the grooves on both sides of the mold allows the abutment 31 to be embedded in the mold groove, forming a reliable mechanical limit and seal for the mold after mold closing, preventing the mold from loosening or shifting during the pouring and curing process, and providing a solid structural foundation for pouring and preventing leakage.

[0023] Both the front and rear limit plates 4 are fixed to the corresponding positions on the upper part of the main body plate 1, and both the front and rear positioning plates 41 are fixed to the corresponding positions on the upper part of the main body plate 1, providing a stable and reliable guiding and limiting foundation for the movement of the movable frame 5. The fixed connection method ensures that the limit plates 4 and positioning plates 41 do not loosen or shift during the operation of the device, ensuring that their guiding and limiting functions on the movable frame 5 remain effective, avoiding the impact of loose parts on the mold closing accuracy, and further improving the overall structural robustness and operational stability of the device.

[0024] The four fastening blocks 51 have an arc-shaped contact surface on the side that contacts the first mold 2 and the second mold 21. The arc-shaped contact surface is fixed to the outer wall of the first mold 2 and the second mold 21 in an arc shape, which increases the contact area between the fastening blocks 51 and the outer wall of the mold. This makes the clamping force of the fastening blocks 51 on the mold evenly distributed on the outer wall of the mold, avoiding mold deformation and misalignment caused by uneven local force. At the same time, it improves the fit between the fastening blocks 51 and the outer wall of the mold, enhances the sealing effect of the mold splicing surface after mold closing, further blocks the leakage path of concrete slurry, and reduces the problem of pouring leakage.

[0025] Working principle: After the device starts the mold closing program, the cylinders 7 at the front and rear ends of the fixed frame 8 output power synchronously. The output end drives the corresponding movable frame 5 to slide linearly along the inner wall of the positioning plate 41. The positioning plate 41 provides precise guidance for the movement of the movable frame 5, avoiding deviation or jamming during the sliding process. While the movable frame 5 slides, it drives the fastening blocks 51 on both sides to move synchronously towards the mold. The fastening block 51 at the front end drives the second mold 21, and the fastening block 51 at the rear end drives the first mold 2 to move closer to each other until the movable frame 5 moves to the limit plate 4. The limit plate 4 forms a precise stroke limit for the movable frame 5. At this time, the first mold 2 and the second mold 21 just complete the coaxial mold closing, and the arc-shaped contact surface of the fastening block 51 is tightly attached to the outer wall of the mold, laying the foundation for subsequent casting and molding. After the first mold 2 and the second mold 21 are closed, the drive motor 62 inside the protective shell 6 starts and outputs rotational power, driving the worm 61 fixed to its output end to rotate smoothly on the inner wall of the front end of the main body plate 1; the worm 61 meshes with the worm wheel 63, transmitting the rotational power to the worm wheel 63, which in turn drives the bidirectional threaded rod 64 fixed to the worm wheel 63 to rotate synchronously in the rotating groove 11; the two sides of the bidirectional threaded rod 64 are threadedly engaged with the inner walls of the two threaded blocks 32, and under its rotation, the two threaded blocks 32 move synchronously in opposite directions along the rotating groove 11, while the slider 33 at the lower rear end of the stabilizer 3 slides synchronously along the slide groove 12 of the main body plate 1. This forms a dual-guide structure, ensuring the straightness and stability of the movement of the stabilizer 3. The two stabilizers 3 move synchronously towards the mold after mold closing, along with the threaded block 32 and the slider 33, driving the outer abutment 31 to move closer to the mold until the abutment 31 is precisely embedded in the grooves on both sides of the first mold 2 and the second mold 21, completing the mechanical limiting and initial sealing of the mold after mold closing. At the same time, the cylinder 7 maintains pressure, and through the movable frame 5, it drives the fastening block 51 to apply a continuous mold closing pre-tightening force to the mold, so that the mold splicing surface fits tightly. Combined with the sealing effect of the abutment 31, it forms a double protection, effectively preventing the grout leakage problem during the subsequent concrete pouring process. After the concrete in the mold is poured and centrifuged, the device starts the demolding procedure. The drive motor 62 starts in reverse, driving the worm gear 61 to rotate in reverse. Through the reverse meshing transmission between the worm gear 61 and the worm wheel 63, the bidirectional threaded rod 64 rotates in reverse in the rotating groove 11, thereby driving the two threaded blocks 32 to move synchronously in opposite directions along the rotating groove 11. The stabilizing seat 3 moves synchronously away from the mold along with the threaded blocks 32 and the slider 33, driving the abutment 31 to disengage from the grooves on both sides of the mold, releasing the seal and limiting of the mold. Then, the cylinder 7 outputs power in reverse, driving the movable frame 5 to slide linearly away from the mold along the positioning plate 41. The movable frame 5 drives the fastening block 51 to move synchronously, thereby pulling the first mold 2 and the second mold 21 to separate from each other, so that the mold is completely separated from the cured cement pole, completing the automated demolding operation. The demolded cement pole can be easily removed, thus completing a complete mold closing, sealing and limiting, and demolding operation process.
