Description

Technical Field

[0001] The utility model relates to the field of casting moulds, in particular to a mould for vertical casting of guard plates. Background Art

[0002] Bridge guard plates are primarily installed on the exterior of rail transit bridges, serving as decoration, pedestrian guardrails, and the foundation for sound barriers. They are precast concrete components. Due to their structural and functional characteristics, they are constructed as a concrete structure combining columns and plates. Furthermore, after installation, they must not interfere with the train's route while still providing protection. Therefore, they are special-shaped precast concrete components.

[0003] Due to the structural characteristics of the guard plate, in order to ensure the smooth casting of the structure, it is generally cast in the form of horizontal casting. However, in order to ensure the appearance quality of the prefabricated components, horizontal casting is generally carried out in batches. The columns are cast after the concrete of the base plate has initially solidified. This casting method results in a long production time for a single component, low mold turnover efficiency, and low effectiveness. At the same time, the open casting surface of the guard plate needs to be polished and leveled manually, which will cause labor waste. At the same time, the quality of the polished surface is difficult to be effectively controlled due to manual operation. At the same time, due to the secondary casting, the interface of the secondary casting is prone to cracking due to inconsistent shrinkage of the concrete, resulting in product quality problems. Therefore, a mold for vertical casting of guard plates is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 2The present invention provides an embodiment of a mold for vertical casting of a guard plate, comprising a support base 1, the top of which is provided with a sliding track to facilitate the movement and adjustment of support blocks 2. The top of the support base 1 is slidably connected to multiple support blocks 2, and the bottom is equipped with a slide rail 3, which can flexibly move on the support base 1; the side of the support base 1 can be closely fitted with the front mold 4, forming part of the main frame of the mold; the bottom of the support block 2 is rotatably connected to two slide rails 3, wherein the adjacent sides of the two support blocks 2 are fixedly connected to the front mold 4, and the right side is provided with a notch 5 to facilitate the opening and closing of the side panel 7. The left side of the front mold 4 is fixedly connected to an auxiliary component for climbing, and the right side of the front mold 4 is provided with two notches 5. The inner wall of the adjacent side of the other two support blocks 2 is fixedly connected to the mold back plate 6, and the bottom end is also slidably connected to the support base 1, forming one side of the closed mold. The bottom end of the mold back plate 6 is slidably connected to the top of the support base 1, and the bottom end of the front mold 4 is slidably connected to the top of the support base 1.

[0032] Reference Figure 1 、 Figure 4 The front and rear sides of the mold back plate 6 are respectively rotatably connected to the side plates 7. The presence of the side plates 7 helps the mold maintain the accuracy of the shape and the integrity of the structure during the pouring process, especially during the concrete curing period. The side plates 7 can resist the pressure from the weight of the concrete and reduce the deformation caused by gravity. The outer wall of the side plate 7 is hinged to the front mold 4, and the outer wall of the side plate 7 is hinged to the outer wall of the top cover 9. The top of the support seat 1 is fixedly connected to the guard plate base 8. The top left side of the front mold 4 is rotatably connected to the top cover 9, covering the top of the guard plate base 8. It can be lifted or lowered as needed to facilitate the pouring of materials and the removal of finished products. The outer wall of the guard plate base 8 is slidably connected to the right inner wall of the support seat 1, and the outer wall of the guard plate base 8 is slidably connected to the inner wall of the slot 5. A pouring port 10 is provided at the top of the side close to the front mold 4 and the mold back plate 6. The front and rear sides of the mold back plate 6 are fixedly connected to a plurality of fixing components for fixing the mold.

[0033] Reference Figures 1 to 3 The fixed component includes a fixed block 11, which serves as a connection point and a bearing structure to ensure the stability of the mold during the casting process. The outer wall of the fixed block 11 is fixedly connected to the outer wall of the mold rear plate 6. A plurality of square openings 12 are provided on the right side of the mold rear plate 6. The plurality of square openings 12 are designed to match the installation of the hinge 13, which provides the necessary space for movement and ensures the rigidity of the structure. The inner wall of the fixed block 11 is rotatably connected to the hinge 13.

[0034] Able to rotate freely within the fixed block 11, this design allows the fixed assembly to adapt to different degrees of tension and relaxation, enhancing the adaptability and reliability of the mold. The outer wall of the hinge 13 is slidably connected to the inner wall of the square opening 12, and the outer wall of the hinge 13 is slidably connected to the right inner wall of the mold back plate 6. The auxiliary components include an inspection platform 14, which serves as an independent operating area and provides a safe and comfortable workstation for workers, especially suitable for high-altitude operations or the execution of complex processes. The right side of the inspection platform 14 is fixedly connected to the left side of the front mold 4. The top left end of the inspection platform 14 is fixedly connected to a platform guard plate 15, which is placed on the top edge of the inspection platform 14 and extends downward to the top of the ladder 16, effectively preventing potential falls and strengthening the safety protection of the work area. The bottom end of the platform guard plate 15 is fixedly connected to the top of the ladder 16, and the right side of the ladder 16 is fixedly connected to the left side of the front mold 4. The ladder 16 is fixedly connected to the bottom rear side of the inspection platform 14.

[0035] Working principle: The support block 2 slides along the track on the support base 1 to finely adjust the position distance between the front mold 4 and the mold back plate 6. This step ensures that the gap between the two meets the exact size of the guard plate to be cast, laying the foundation for subsequent processes. Turn the side panel 7, and use its linkage effect with the hinge 13 to prompt the hinge 13 to snap into the square opening 12 on the mold back plate 6. This action is equivalent to activating an automatic clamping system. As the hinge 13 goes deeper, pressure is gradually applied to make the front mold 4 and the mold back plate 6 fit more tightly, forming a highly sealed casting space. After finally confirming that all components are ready, gently turn the top cover 9 to expose the casting port 10. At this point, the guard plate base 8 is in the correct position, playing a crucial role in sealing and ensuring a tight, gap-free bottom, creating favorable conditions for pouring. Casting begins, and concrete or other materials are slowly poured through the pouring port 10. Thanks to the precise positioning and tight sealing measures taken in the early stages, the pouring process is smooth and orderly, reducing bubbles and unevenness, and ensuring the quality of the guard plate's one-shot molding. After the cast material hardens, the above steps are reversed, sequentially unlocking the side panels 7, opening the top cover 9, and finally slowly separating the front mold 4 and the rear mold plate 6. Leveraging the mold's inherent fine-tuning properties, demolding is effortless, resulting in a complete and intact prefabricated guard plate.

[0036] When the top cover 9 is in a horizontal state after closing, the top cover of the mold is the installation base of the guard plate, which plays a good sealing role. After the concrete is poured, bubbles will be enriched at the bottom of the top cover, forming a similar roughened surface, which can avoid secondary roughening of the guard plate during installation.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
