Description

Technical Field

[0001] This utility model relates to the field of electric pole production molds, specifically a cement electric pole production mold. Background Technology

[0002] Cement poles are a widely used support structure in the construction of infrastructure such as power and communications. Currently, the production of cement poles typically relies on specific molds, and the performance and quality of these molds directly affect the production efficiency and product quality of the cement poles.

[0003] Existing mold structures are complex to assemble and disassemble, requiring significant manpower and time. The connection methods between different components are not convenient enough, resulting in low production efficiency and failing to meet the demands of large-scale production. Furthermore, the complex assembly process is prone to inaccurate installation, affecting the overall precision of the mold and consequently the dimensional accuracy and shape quality of the cement poles. Therefore, we propose a new cement pole production mold. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cement pole production mold, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a cement pole production mold, comprising a tubular object, an intermediate connecting ring, and a sealing assembly for sealing the ends of the tubular object. The intermediate connecting ring is disposed between two adjacent tubular objects. The tubular object is composed of two mirror-arranged arc-shaped shells. The cross-section of the arc-shaped shell is arc-shaped, and grooves are provided at both ends of the arc-shaped shells. When the two arc-shaped shells are fitted together, the two grooves form an annular groove. An annular protrusion is integrally formed on the intermediate connecting ring at the position corresponding to the annular groove, and the annular protrusion engages with the annular groove.

[0006] Preferably, the sealing component includes an end plug, and an annular protrusion is integrally formed on the end plug at the position corresponding to the annular groove. The annular protrusion engages with the annular groove on the end of the tubular object opposite to the middle connecting ring.

[0007] Preferably, the two ends of the arc-shaped outer shell are integrally formed with connecting protrusion two, and the middle connecting ring and the end block are integrally formed with connecting protrusion three and connecting protrusion one respectively at the positions corresponding to connecting protrusion two.

[0008] Preferably, one of the arc-shaped outer shells has a rectangular groove on its side, and the other end block has a strip-shaped protrusion integrally formed on its side. When the two end blocks are fitted together, the strip-shaped protrusion engages with the rectangular groove to increase the airtightness.

[0009] Preferably, each of the arc-shaped shells has a side strip block integrally formed at the arc-shaped side end position, and the side strip blocks at the ends of the two corresponding arc-shaped shells are fixed by a snap-fit ​​assembly.

[0010] Preferably, the snap-fit ​​assembly includes a tension spring and a connecting block. Rectangular grooves are equally spaced on the side wall of the side strip block away from the arc-shaped shell. A tension spring is fixedly installed in one of the rectangular grooves on the side strip block. A plug-in block is integrally formed on the connecting block at the position corresponding to the rectangular groove. The plug-in block snaps into the two rectangular grooves respectively, and the plug-in block corresponding to the tension spring is fixedly connected to the tension spring.

[0011] Compared with the prior art, this utility model provides a cement pole production mold, which has the following beneficial effects:

[0012] Improved sealing performance

[0013] Annular sealing structure: Grooves are created at both ends of the arc-shaped outer shell, and the two arc-shaped outer shells fit together to form an annular groove. Annular protrusion one on the connecting ring in the middle and annular protrusion two on the end plug respectively engage with the annular groove. This annular engaging structure effectively prevents cement slurry from leaking from the connection points of adjacent tubular objects and the ends of the tubular objects when flowing inside the mold, greatly improving the overall sealing of the mold, ensuring the molding quality of the cement pole, and reducing surface defects and raw material waste caused by cement slurry leakage.

[0014] Side sealing design: A rectangular groove on the side of one of the curved shells engages with a strip protrusion on the side of the other curved shell, further enhancing the seal between the two curved shells. This design prevents cement slurry from seeping out from the gaps on the side of the mold, ensuring that the sides of the cement pole are smoothly and flat, improving the appearance quality and overall performance of the product.

[0015] Easy and efficient assembly

[0016] Modular design: The mold adopts a modular design, consisting of multiple arc-shaped shells forming a tubular object, which is connected and sealed by a central connecting ring and end plugs. When manufacturing cement poles, the number of tubular objects can be flexibly selected according to the required pole length, and the mold length can be easily and quickly adjusted to meet the production needs of cement poles of different specifications, thus improving the mold's versatility and applicability.

[0017] Quick-connect snap-fit ​​and bolt connection: The snap-fit ​​structure between the annular protrusion and the annular groove, along with the bolt connection between the connecting protrusions, makes the assembly process of each part of the mold simple and efficient. The snap-fit ​​structure allows for quick initial positioning of each part of the mold, followed by further fixing with bolts to ensure a strong connection. At the same time, this connection method facilitates disassembly, allowing the mold to be quickly disassembled after the cement pole is formed, improving production efficiency.

[0018] Enhanced connection stability

[0019] Multi-part reinforcement: In addition to the snap-fit ​​between the annular protrusion and the annular groove, and the bolt connection between the connecting protrusions, the side strips at the ends of each arc-shaped shell are fixed by snap-fit ​​components. The tension spring and connecting block in the snap-fit ​​components work together to ensure that the two arc-shaped shells are tightly connected together. This multi-part connection method greatly enhances the overall connection stability of the mold, effectively resisting the weight and pressure of the cement during the cement pouring process, preventing the mold from deforming or loosening, and ensuring the dimensional accuracy and shape quality of the cement pole.

[0020] Simple and practical structure

[0021] One-piece molding design: The various protrusions and grooves on the curved outer shell, intermediate connecting ring, and end plugs are all manufactured using a one-piece molding process, reducing the number of parts and assembly steps, and lowering the production cost and manufacturing difficulty of the mold. At the same time, the one-piece molding structure has higher strength and stability, extending the service life of the mold. Attached Figure Description
