Description

Technical Field

[0001] This utility model relates to the field of cement pole production technology, and more specifically, to a molding device for cement pole products. Background Technology

[0002] In urban construction and development, the construction of power grids is a crucial component, with the use of cement poles being particularly important. Cement poles are mainly composed of steel bars and concrete, and are primarily used as overhead line supports in industries such as power, telecommunications, railways, and petroleum. In the production process of cement poles, concrete and steel bars are mixed in a specific ratio, and concrete is poured into a special mold. Multiple steel bars are then evenly inserted into the concrete, ensuring that the steel bars are evenly distributed within the concrete. After the concrete has cured, the poles are demolded, thus producing the finished cement pole.

[0003] However, there are various types of molding equipment in the existing technology. For example, utility model patent CN218111193U relates to a molding equipment for processing cement poles. This utility model includes a cement pole mold, and the outer wall of the cement pole mold is equipped with a demolding structure. The demolding structure includes a locking block, which is installed on the outer wall of the cement pole mold. The outer wall of the cement pole mold has an impact groove, and an impact block is installed inside the impact groove. A spring is installed at the bottom end of the impact block. The outer side of the cement pole mold is fitted with a reinforcing locking structure, and a rotating shaft is installed on the outer wall of the cement pole mold. This utility model, by setting up a demolding structure, allows the cement pole to be quickly demolded after it has solidified inside the cement pole mold. By rotating the locking block at the top of the cement pole mold, the spring inside the impact groove will cause the impact block to pop out. The impact of the impact block will cause the internal cavity of the cement pole mold to vibrate, allowing the internal cement pole to be quickly demolded, thus achieving the function of easy demolding.

[0004] Although this molding equipment facilitates demolding of cement pole products and achieves mold sealing, during the cement pouring process, the reinforcing bars are placed inside the device. The impact force generated by the cement during pouring acts on the reinforcing bars, causing them to shift. This affects the uniform distribution of the reinforcing bars and reduces the compressive strength and durability of the cement pole after molding. To avoid this phenomenon, it is essential to design a molding device for cement pole products. Utility Model Content

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0030] like Figure 1 , Figure 2 , Figure 3 as well as Figure 5 The diagram shows the structure of the molding device for cement pole products in this embodiment. The molding device includes a first mold shell 1, a second mold shell 2 on one side of the first mold shell 1, a connecting plate 3 at one end of the first mold shell 1 and the second mold shell 2, and a limiting plate 5 at the other end of the first mold shell 1 and the second mold shell 2. The connecting plate 3 has several insertion holes 4, and the limiting plate 5 has several positioning holes 6. Sealing rings 7 are provided on the surfaces of the connecting plate 3 and the limiting plate 5 that are close to each other. Sealing grooves 8 are provided at both ends of the first mold shell 1 and the second mold shell 2, and sealing gaskets 9 are provided inside the sealing grooves 8. The sealing rings 7 can be embedded in the sealing grooves 8. Two threaded mounting holes 10 are provided at both ends of the first mold shell 1 and the second mold shell 2, and connecting rings 7 are threaded into the threaded mounting holes 10. Connecting bolt 11 is inserted through connecting plate 3 and limiting plate 5. Before cement pouring, multiple reinforcing bars are inserted into several insertion holes 4 to place them into the mold shell. Then, connecting plate 3 is attached to one end of the first mold shell 1 and the second mold shell 2, and sealing ring 7 is embedded in sealing groove 8 to seal one end of the mold shell. Then, multiple reinforcing bars are inserted into corresponding positioning holes 6 to limit their position, ensuring that the reinforcing bars are evenly distributed in the mold shell. Limiting plate 5 is attached to the other end of the first mold shell 1 and the second mold shell 2 to seal the other end of the mold shell. This positions the reinforcing bars in the mold shell, preventing them from shifting due to the impact of cement pouring, thus ensuring that the reinforcing bars are evenly distributed in the mold shell and improving the compressive strength and durability of the cement rod after molding.

[0031] It is worth noting that in this embodiment, several insertion holes 4 correspond to several positioning holes 6, and the diameters of the insertion holes 4 and the positioning holes 6 are the same; the first mold shell 1 is provided with a docking groove 22, and the second mold shell 2 is provided with a protrusion, which can be embedded in the interior of the docking groove 22. After the first mold shell 1 and the second mold shell 2 are combined, the protrusion is embedded in the docking groove 22 to seal the interior of the mold shell.

[0032] like Figure 9 As shown, in this embodiment, two mounting rings 25 are fitted onto the first mold shell 1 and the second mold shell 2. The outer surface of the mounting rings 25 is provided with guide grooves, and the mounting rings 25 are provided with two assembly holes 26, which are located inside the guide grooves. After the first mold shell 1 and the second mold shell 2 are assembled, the two mounting rings 25 are fitted onto the mold shells, and bolts are inserted into the assembly holes 26 respectively to fix the position of the mounting rings 25. Then, the device with the mounting rings 25 is placed on the centrifuge. With the help of the guide groove, the operator can insert the rotating wheel of the centrifuge into the guide groove. Driven by the rotating wheel, the mounting rings 25 can be rotated, so that the entire device rotates centrifugally with the mounting rings 25. In this way, the centrifugal force is used to make the cement evenly adhere to the inner wall of the mold shell to form a hollow cement pole.

[0033] like Figure 7 As shown, in this embodiment, the outer walls of the first mold shell 1 and the second mold shell 2 are provided with multiple longitudinal reinforcing ribs 23, and the multiple longitudinal reinforcing ribs 23 are distributed at equal intervals. Multiple transverse reinforcing ribs 24 are fixedly connected between the multiple longitudinal reinforcing ribs 23. By using the multiple longitudinal reinforcing ribs 23 and the multiple transverse reinforcing ribs 24 arranged in an alternating manner, the structural strength of the entire mold shell is increased, and the service life of the molding device is improved.

[0034] like Figure 4 as well as Figure 6 As shown, in this embodiment, the limiting plate 5 is provided with a pouring port 12, and the pouring port 12 is located in the center of the limiting plate 5. A sealing cover plate 13 is embedded inside the pouring port 12. Multiple snap-fit ​​plates 14 are fixedly connected to the sealing cover plate 13. Each snap-fit ​​plate 14 has a snap-fit ​​groove. Multiple threaded posts 15 are fixedly connected to the limiting plate 5, and the threaded posts 15 can be snapped into the corresponding snap-fit ​​grooves. Fastening bolts 16 are threadedly connected to the surface of the threaded posts 15. During the cement pouring process, cement is injected into the mold shell through the pouring port 12. Then, the sealing cover plate 13 is embedded into the pouring port 12, and the multiple threaded posts 15 are snapped into the snap-fit ​​grooves respectively. Then, the fastening bolts 16 are tightened to fix the sealing cover plate 13, thereby sealing the pouring port 12.

[0035] like Figure 7 as well as Figure 8 As shown, in this embodiment, the first mold shell 1 and the second mold shell 2 are provided with multiple grooves 17, which are distributed at equal intervals. The outer wall of the second mold shell 2 is fixedly connected to multiple sets of support plates 18. A rotating shaft is provided between each set of support plates 18 through a bearing. A connecting ball sleeve 19 is coaxially provided on the surface of the rotating shaft. A threaded limiting rod 20 is fixedly connected to the connecting ball sleeve 19. A fastening sleeve 21 is threadedly connected to the surface of the threaded limiting rod 20. In order to seal the first mold shell 1 and the second mold shell 2, the first mold shell 1 and the second mold shell 2 are put together. The rotating shaft rotating between the two support plates 18 drives the connecting ball sleeve 19 to rotate, deflecting the threaded limiting rod 20 fixed on the connecting ball sleeve 19 so that the threaded limiting rod 20 rotates into the groove 17. Then, the fastening sleeve 21 is tightened by the threaded engagement between the threaded limiting rod 20 and the fastening sleeve 21. The mold shells are pressed by multiple fastening sleeves 21, thereby sealing the first mold shell 1 and the second mold shell 2.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
