Description

Technical Field

[0001] This invention relates to the field of assembly mold technology, and in particular to a mold for an assembly-type steel structure corner hanging plate. Background Technology

[0002] With the development of the construction industry and the increasing maturity of precast concrete structures, prefabricated steel structures have also become a research focus. Existing steel structure corner cladding panels are prefabricated in the factory by using molds to fill the gaps between concrete columns and concrete outer leaves, and finally installed on the construction site.

[0003] Current molds, such as the one disclosed in Chinese Patent Publication No. CN111391076B for factory-assembled steel structure corner cladding panels, require concrete to be poured into the mold during use. However, air bubbles and uneven concrete dispersion easily occur during the molding process, resulting in air bubbles and inconsistent compactness in the finished product. Therefore, this invention proposes a mold for prefabricated steel structure corner cladding panels. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mold for prefabricated steel structure corner hanging panels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mold for a prefabricated steel structure corner cladding panel includes a mold closing assembly, a reciprocating assembly, and a simultaneous opening assembly;

[0007] The mold assembly is used to shape and mold concrete, and the mold assembly includes a fixed steel frame and a mold frame fixed on the fixed steel frame.

[0008] The reciprocating assembly is driven by electricity to complete the up-and-down reciprocating sliding motion. The reciprocating assembly includes a motor and a rotating rod fixedly installed at the motor drive end.

[0009] The simultaneous opening assembly is used to block and release excess and missed concrete material. The simultaneous opening assembly includes two rotating plates and a baffle fixedly connected to the bottom of the rotating plates.

[0010] Preferably, two electro-hydraulic rods are provided on one inner wall of the mold closing frame, and four electro-hydraulic rods are provided on the other inner wall of the mold closing frame. A first template is fixedly provided on one side of the two electro-hydraulic rods, and a second template is fixedly provided on one side of the four electro-hydraulic rods. A feed groove is provided on one side of the first template, and an electric controller is fixedly provided on both sides of the mold closing frame.

[0011] Preferably, an inner chamber is provided on the side of the first template away from the feed chute, a fixing plate is fixedly provided on the outer side of the inner chamber and on the first template, a fixing block is fixedly provided on the inner wall of one side of the inner chamber, the rotating rod and the fixing block are rotatably connected, a worm gear is fixedly provided on the rotating rod, and a first rotating shaft is rotatably connected on the inner wall of the fixing plate and inside the inner chamber, and a worm wheel is fixedly connected on the first rotating shaft.

[0012] Preferably, a first gear is fixedly disposed on the first rotating shaft and located on one side of the worm gear, and a second rotating shaft is rotatably connected to the inner wall of the fixed plate and located inside the inner chamber. A second gear is fixedly disposed on the second rotating shaft, a first sector tooth is fixedly disposed on the first rotating shaft and located on the side of the first gear away from the worm gear, and a second sector tooth is fixedly disposed on the side of the second rotating shaft close to the first sector tooth.

[0013] Preferably, a guide rod is fixedly connected inside the inner compartment, and a slider is slidably connected through the guide rod. A toothed plate is fixedly provided on the side of the slider near the first sector tooth.

[0014] Preferably, the inner wall of the inner chamber is provided with a tamping component for continuously reciprocating to tamp and stir the inside of the feed trough. The tamping component includes two through holes opened inside the inner chamber, one through hole opened on the inner wall of the inner chamber and the other through hole opened on the side wall of the first template near the feed trough. The two through holes are interconnected by a horizontal hole, wherein a sliding rod is slidably installed inside the horizontal hole.

[0015] Preferably, a push block is fixedly provided on the side of the slide rod near the inner chamber and slidably connected to a through hole, and a spring is fixedly provided between the push block and the inner wall of the through hole. A tamping block is fixedly provided on the side of the slide rod near the feed chute and slidably connected to a through hole on the other side.

[0016] Preferably, the bottom of the mold frame is provided with a return port, and two rotating plates are rotatably connected to the outer wall of the return port. A third gear is fixedly provided on the rotating node of the rotating plate. Two other rotating plates are also rotatably connected to the outer wall of the return port. Another baffle and a third gear are also fixedly provided at the bottom and on the rotating node. The two third gears mesh with each other, and the two sets of rotating plates are movably connected to each other by a cylinder.

[0017] Preferably, the worm and the worm wheel mesh with each other, and the first gear and the second gear mesh with each other.

[0018] Preferably, both the first sector tooth and the second sector tooth intermittently mesh with the tooth plate, and the tooth directions of the first sector tooth and the second sector tooth are opposite to each other.

[0019] The present invention has the following beneficial effects:

[0020] 1. By setting up a reciprocating assembly, the motor drives the rotating rod to rotate the worm gear. Through the meshing transmission between the worm gear and the worm wheel, the first and second rotating shafts rotate in conjunction, causing the first and second sector teeth to intermittently mesh with the toothed plate, driving the slider to slide back and forth along the guide rod. This mechanical transmission structure can convert the rotational motion of the motor into the linear reciprocating motion of the slider without an additional power source, resulting in high transmission efficiency and strong stability.

[0021] 2. By setting up a tamping component as the actuator, the slider reciprocates to push the push block, compressing or releasing the spring, driving the slide rod to drive the tamping block to tampe at high frequency in the feed trough. On the one hand, it can fully mix the poured concrete and avoid aggregate accumulation; on the other hand, it can effectively remove air bubbles inside the concrete, enhance the bonding force between the concrete and the steel structure, and improve the structural strength and durability of the corner cladding panel. It is especially suitable for the production needs of high-strength cladding panels.

[0022] 3. The design of the simultaneous opening component enables coordinated control of surplus material recycling and the pouring process, combining environmental protection and practicality. The return port at the bottom of the mold frame provides a discharge channel for excess concrete, while the combination structure of two rotating plates, baffles, and a third gear achieves synchronous opening and closing through cylinder drive: after the concrete is poured, the cylinder extends and retracts, driving one set of rotating plates to rotate, and through two meshing third gears, the other set of rotating plates rotates synchronously, causing the baffle to open. Excess or missed concrete is collected and recycled through the return port, avoiding concrete waste and reducing production costs. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1:

[0036] Reference Figures 1-4 A mold for a prefabricated steel structure corner cladding panel, comprising a mold closing assembly, a reciprocating assembly, and a simultaneous opening assembly;

[0037] The mold assembly is used to shape and mold concrete. The mold assembly includes a fixed steel frame 1 and a mold frame 2 fixed on the fixed steel frame 1.

[0038] The reciprocating assembly is driven by electricity to complete the up-and-down reciprocating sliding motion. The reciprocating assembly includes a motor 11 and a rotating rod 13 fixedly installed at the drive end of the motor 11.

[0039] The simultaneous opening assembly is used to block and release excess and missed concrete material. The simultaneous opening assembly includes two rotating plates 29 and a baffle 30 fixedly connected to the bottom of the rotating plates 29.

[0040] Two electric hydraulic rods 4 are installed on one inner wall of the mold-closing frame 2, and four electric hydraulic rods 4 are installed on the other inner wall of the mold-closing frame 2. A first template 5 is fixedly installed on one side of the two electric hydraulic rods 4, and a second template 6 is fixedly installed on one side of the four electric hydraulic rods 4. A feeding groove 7 is opened on one side of the first template 5. Electric controllers 8 are fixedly installed on both sides of the mold-closing frame 2. It should be noted that the double templates, together with the mold-closing frame 2, form a closed forming cavity, which fits the corner structure design of the corner hanging plate, ensuring that the angle of the formed hanging plate is accurate and the shape is regular. The feeding groove 7 of the first template 5 provides a directional channel for concrete pouring, avoiding concrete splashing during pouring, and also facilitating the insertion of the vibration component. The design of the inner chamber 9 provides built-in installation space for the reciprocating component and the vibration component, realizing the hidden layout of functional components, not occupying external operating space, and protecting the internal transmission structure from concrete contamination.

[0041] In this embodiment, the electric controller 8 is activated to control the synchronous extension and retraction of the electric hydraulic rod 4, driving the first template 5 and the second template 6 to move towards the center of the mold-closing frame 2 until a closed corner forming cavity is formed. During this process, the electric hydraulic rod 4 adopts a hydraulic drive method, with large output force and high adjustment accuracy, which can accurately control the opening and closing distance and locking force of the template, adapting to the production needs of different specifications of products. The distributed arrangement of multiple hydraulic rods ensures that the template is subjected to balanced force, avoiding forming defects caused by excessive local pressure. At the same time, the frame structure of the mold-closing frame 2 provides a stable installation space for the double templates, and the side wall enclosure strictly limits the concrete forming range, ensuring the regularity of the corner hanging plate. After the mold is closed, the locking status of the template is checked again by the electric controller 8 to ensure that there is no looseness or gap.

[0042] Furthermore, the well-mixed concrete is slowly injected into the forming cavity through the feed trough 7 of the first template 5. The directional channel design of the feed trough 7 avoids splashing during concrete pouring and provides operating space for the subsequent vibration components. During the pouring process, the concrete injection speed is controlled to ensure that the cavity is gradually filled and to avoid the generation of a large number of air bubbles or concrete overflow due to excessive injection.

[0043] Example 2:

[0044] Reference Figures 5-9Compared to Embodiment 1, in this embodiment, an inner chamber 9 is provided on the side of the first template 5 away from the feed chute 7. A fixing plate 10 is fixedly installed on the outer side of the inner chamber 9 and on the first template 5. A fixing block 12 is fixedly installed on the inner wall of one side of the inner chamber 9. The rotating rod 13 is rotatably connected to the fixing block 12. A worm gear 14 is fixedly installed on the rotating rod 13. A first rotating shaft 15 is rotatably connected on the inner wall of the fixing plate 10 and inside the inner chamber 9. A worm wheel 17 is fixedly connected to the first rotating shaft 15. It should be noted that the worm gear transmission has the characteristics of large reduction ratio and strong self-locking. It can convert the high-speed rotation of the motor into the low-speed and smooth rotation of the worm wheel 17, providing a suitable speed for the subsequent intermittent transmission of the sector gear. The self-locking function can prevent the transmission structure from reversing due to external forces such as tamping reaction force when there is no power input, ensuring the stability and safety of reciprocating motion.

[0045] A first gear 18 is fixedly mounted on the first rotating shaft 15 and located on one side of the worm gear 17. A second rotating shaft 16 is rotatably connected to the inner wall of the fixed plate 10 and located inside the inner chamber 9. A second gear 19 is fixedly mounted on the second rotating shaft 16. A first sector tooth 20 is fixedly mounted on the first rotating shaft 15 and located on the side of the first gear 18 away from the worm gear 17. A second sector tooth 21 is fixedly mounted on the second rotating shaft 16 and located on the side of the second sector tooth 20. It should be noted that the gear meshing transmission is precise, ensuring that the two rotating shafts rotate at the same speed and in opposite directions, thus guaranteeing the alternating action of the first sector tooth 20 and the second sector tooth 21. By adjusting the direction of force transmission through gear transmission, the power of a single motor can drive the two sets of sector teeth to work together, simplifying the power structure and reducing equipment costs.

[0046] Inside the inner chamber 9, a guide rod 22 is fixedly connected, and a slider 23 is slidably connected through the guide rod 22. A toothed plate 24 is fixedly installed on the side of the slider 23 near the first sector tooth 20. It should be noted that the intermittent meshing design of the sector teeth can convert the continuous rotation of the shaft into the reciprocating linear motion of the toothed plate 24. When the first sector tooth 20 meshes with the toothed plate 24, it drives the toothed plate to slide forward; when the second sector tooth 21 meshes with the toothed plate 24, it drives the toothed plate to slide backward. No additional reversing device is required, the structure is simple and the action is smooth. The design of opposite tooth directions ensures the smoothness of the reciprocating motion, avoids jamming, and improves the stability of the tamping frequency.

[0047] In addition, the guide rod 22 ensures that the slider 23 slides in a fixed direction, preventing the toothed plate 24 from deviating when meshing with the sector teeth, thus improving transmission accuracy; the fixed connection between the slider 23 and the toothed plate 24 converts the rotational power of the sector teeth into linear thrust, providing a stable reciprocating driving force for the tamping assembly; the sliding connection between the slider 23 and the guide rod 22 has low frictional resistance, reduces energy loss, and improves transmission efficiency.

[0048] The inner wall of the inner chamber 9 is equipped with a tamping component for continuously reciprocating and agitating the interior of the feed trough 7. The tamping component includes two through holes inside the inner chamber 9: one through hole is located on the inner wall of the inner chamber 9, and the other through hole is located on the side wall of the first template 5 near the feed trough 7. The two through holes are interconnected by a transverse hole, through which a sliding rod 25 is slidably mounted. It should be noted that this core component, which transmits the reciprocating thrust of the slider 23 to the tamping block 28, has a strong structural rigidity, is not easily bent or deformed, ensures effective transmission of the tamping force, avoids jamming during movement, and guarantees the continuity of the tamping action.

[0049] A push block 26 is fixedly installed on the side of the slide rod 25 near the inner chamber 9, and is slidably connected to a through hole. A spring 27 is fixedly installed between the push block 26 and the inner wall of the through hole. A tamping block 28 is fixedly installed on the side of the slide rod 25 near the feed chute 7, and is slidably connected to a through hole on the other side. It should be noted that the push block 26 increases the contact area between the slider 23 and the slide rod 25, avoiding excessive local force that could damage the components. The elastic return design of the spring 27 can quickly push the push block 26 and the slide rod 25 back to their original position when the slider 23 slides in the opposite direction, increasing the tamping frequency. At the same time, the spring 27 can buffer the reaction force during the tamping process, reduce the impact on the transmission structure, and extend the service life of the components.

[0050] In addition, the vibrating block 28 acts directly on the concrete, and its reciprocating motion can effectively remove air bubbles inside the concrete, avoiding defects such as honeycomb and pitting after molding; at the same time, it can stir the concrete in the feed trough 7, prevent material accumulation, ensure uniform concrete mix ratio, and improve the structural strength and surface quality of the outer panel; the sliding fit design of the vibrating block 28 and the through hole prevents concrete from entering the inner chamber 9, ensuring the cleanliness of the internal transmission structure.

[0051] In this embodiment, the motor 11 of the reciprocating assembly is started, and the motor 11 outputs stable rotational power, driving the rotating rod 13 to rotate around the fixed block 12, which in turn drives the worm gear 14 to rotate synchronously. Through the meshing transmission between the worm gear 14 and the worm wheel 17, the high-speed rotation of the motor is converted into the low-speed, smooth rotation of the worm wheel 17. Taking advantage of the large reduction ratio and strong self-locking of the worm gear, the reverse rotation caused by external force is avoided, thereby driving the first rotating shaft 15 to rotate. The first gear 18 on the first rotating shaft 15 meshes with the second gear 19 on the second rotating shaft 16, causing the two rotating shafts to rotate synchronously in opposite directions. The first sector tooth 20 and the second sector tooth 21 fixed on the rotating shaft rotate alternately accordingly.

[0052] Furthermore, since the first sector tooth 20 and the second sector tooth 21 have opposite tooth directions and intermittently mesh with the toothed plate 24, when the first sector tooth 20 meshes with the toothed plate 24, it drives the toothed plate 24 and the slider 23 to slide forward along the guide rod 22 to ensure accurate sliding direction and avoid deviation; when the second sector tooth 21 meshes with the toothed plate 24, it drives the toothed plate 24 and the slider 23 to slide in the opposite direction, realizing the reciprocating linear motion of the slider 23. During the reciprocating sliding of the slider 23, it continuously pushes the push block 26 of the tamping assembly. After the push block 26 compresses the spring 27, it transmits the thrust to the tamping block 28 through the slide rod 25, causing the tamping block 28 to reciprocate within the feed trough 7.

[0053] Furthermore, the high-frequency vibration of the tamping block 28 thoroughly mixes the concrete, preventing aggregate accumulation and ensuring a uniform concrete mix ratio. It also effectively removes air bubbles from the concrete, preventing defects such as honeycomb and pitting after molding, thus improving the structural strength and surface quality of the outer panel. Simultaneously, the elastic reset design of the spring 27 quickly pushes the push block 26 and slide rod 25 back to their original positions when the slider 23 slides in the reverse direction, increasing the vibration frequency. The push block 26 increases the contact area between the slider and slide rod, preventing excessive localized stress that could damage components, while the sliding fit between the slide rod 25 and the transverse hole ensures continuous and uninterrupted tamping. In addition, the enclosed design of the inner chamber 9 prevents concrete or dust from entering the transmission components, ensuring the cleanliness and lifespan of the reciprocating and tamping components.

[0054] Example 3:

[0055] Reference Figures 1-3 and Figure 10 Compared to Embodiments 1 and 2, in this embodiment, the bottom of the mold frame 2 is provided with a return port 3. Two rotating plates 29 are rotatably connected to the outer wall of the return port 3. A third gear 31 is fixedly installed on the rotating node of the rotating plate 29. Two other rotating plates 29 are also rotatably connected to the outer wall of the return port 3. Additionally, another baffle 30 and a third gear 31 are fixedly installed at the bottom and rotating node. The two third gears 31 mesh with each other. The two sets of rotating plates 29 are movably connected to each other via a cylinder 32. It should be noted that the flipping action of the rotating plate 29 drives the baffle 30 to move synchronously, realizing the rapid opening and closing of the return port 3. When the baffle 30 is closed, it ensures no leakage during concrete pouring; when it is open, it quickly discharges excess concrete, balancing molding quality and waste material recovery. The symmetrical design of the two sets of rotating plates 29 ensures uniform force on the return port 3, avoiding localized wear.

[0056] In addition, the gear meshing transmission enables the synchronous reverse flipping of the two sets of rotating plates 29, ensuring that the baffle 30 opens and closes in unison, avoiding leakage of residual material or incomplete recycling due to unilateral opening and closing. It responds quickly and can be driven in coordination with the cylinder 32 to improve the coordination of component actions.

[0057] In this embodiment, after the tamping operation is completed, if there is excess or missing concrete in the cavity, the cylinder 32 of the simultaneous opening component is activated. The cylinder 32 has sufficient power and responds quickly. When it extends or retracts, it drives a set of rotating plates 29 to rotate around the rotation node of the return port 3. Through the linkage of two sets of meshing third gears 31, the other set of rotating plates 29 rotates synchronously in the opposite direction, thereby driving the baffle 30 to open. The meshing transmission of the third gears 31 ensures that the baffle opens and closes in unison, avoiding leakage of excess material caused by unilateral opening and closing. Excess concrete is discharged and recycled through the return port 3 at the bottom of the mold frame 2. The size design of the return port 3 is adapted to common amounts of excess material, ensuring smooth discharge without blockage.

[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
