[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] refer to Figure 1 , Figure 2 and Figure 4 In this embodiment: a mold for producing utility poles includes an upper mold shell 1, and an installation assembly is provided on the outer wall of the upper mold shell 1;

[0025] The mounting assembly includes a lower mold shell 4, which is detachably connected to an upper mold shell 1. Multiple evenly distributed mounting blocks 8 are fixedly connected to the outer surface of the upper mold shell 1. A fixing block 9 is fixedly connected to the bottom of each mounting block 8. Fixing grooves 10 are provided at both ends of each fixing block 9. Multiple evenly distributed mounting blocks 14 are fixedly connected to the outer periphery of the lower mold shell 4. Slide strips 18 penetrate both ends of each mounting block 14. Springs 19 are fitted around the outer periphery of each slide strip 18. A limiting block 15 is fixedly connected to one side of each slide strip 18, and the limiting block 15 matches the fixing groove 10. A limiting plate 11 is fitted around the outer periphery of each slide strip 18. A lever 12 is fixedly connected to the end of each slide strip 18 away from the limiting block 15. Two evenly distributed sliding grooves 16 are provided on one side wall inside the mounting block 14, and the limiting plate 11 is slidably connected to the sliding grooves 16.

[0026] Specifically, a spring 19 is fitted around the outer periphery of the slide bar 18 that runs through both ends of the mounting block 2 14. The spring 19 is in a naturally extended state, and the limiting block 15 on the opposite side of the slide bar 18 tends to move towards the fixed block 9 under the elastic force of the spring 19. As the upper mold shell 1 continues to move closer to the lower mold shell 4, the fixed block 9 and the limiting block 15 slide against each other, thereby squeezing the spring 19 and causing it to deform. This, in turn, causes the two slide bars 18 to slide apart. When the fixed block 9 and the limiting block 15 slide to a certain position, the limiting block 15 is inserted into the fixing groove 10 under the action of the spring 19, thereby achieving a tight connection between the upper mold shell 1 and the lower mold shell 4.

[0027] refer to Figure 4 In this embodiment, the bottom of the slide bar 18 is rotatably connected to the limiting rod 17, and the outer two side walls of the mounting block 14 are provided with limiting grooves 13. The limiting grooves 13 match the bottom of the limiting rod 17, the slide bar 18 is slidably connected to the side wall of the mounting block 14, and the limiting block 15 is slidably connected to the fixing groove 10.

[0028] Specifically, when it is necessary to disassemble the mold, the operator can manually move the lever 12. The lever 12 drives the slide bar 18 to move outward against the elastic force of the spring 19. At this time, rotate the limiting rod 17 so that the limiting rod 17 abuts against the limiting groove 13. The operator does not need to hold the lever continuously. The limiting block 15 disengages from the fixed groove 10, and the upper mold shell 1 and the lower mold shell 4 can be easily separated.

[0029] refer to Figure 2 and Figure 3 In this embodiment, multiple evenly distributed reinforcing ribs 2 are fixedly connected to the outer periphery of the upper mold shell 1 and the lower mold shell 4. Clamping rings 3 are fixedly connected to the outer periphery of both the upper mold shell 1 and the lower mold shell 4. Two evenly distributed rotating tracks 5 are fixedly connected to the outer periphery of both the upper mold shell 1 and the lower mold shell 4. A limiting groove 6 is provided at one end of the upper mold shell 1 near the lower mold shell 4. A limiting protrusion 7 is provided at one end of the lower mold shell 4 near the upper mold shell 1. The limiting protrusion 7 matches the limiting groove 6.

[0030] Specifically, during the production of utility poles, the multiple evenly distributed reinforcing ribs 2 fixedly connected to the outer periphery of the upper mold shell 1 and the lower mold shell 4 effectively enhance the overall structural strength of the mold. When concrete is poured into the mold, the reinforcing ribs 2 help the mold withstand the pressure generated by the concrete, preventing the mold from deforming due to excessive pressure. The clamping ring 3 facilitates the handling and fixing of the mold on the production line. During mold transfer, the clamping ring 3 is connected to hoisting equipment or other handling tools to ensure stable mold movement and prevent damage to the mold due to shaking or collision. The rotating track 5 facilitates centrifugal operation of the mold. The limiting protrusion 7 of the lower mold shell 4 abuts against the limiting groove 6 of the upper mold shell 1, reducing the probability of concrete overflow and the frequency of cleaning by workers.

[0031] The working principle and usage process of this utility model: The slide bar 18, which runs through both ends of the installation block 2 14, is fitted with a spring 19 on its outer periphery. The spring 19 is in a naturally extended state. The limiting block 15 on the opposite side of the slide bar 18 tends to move towards the fixed block 9 under the elastic force of the spring 19. As the upper mold shell 1 continues to approach the lower mold shell 4, the fixing block 9 and the limiting block 15 slide against each other, thereby squeezing the spring 19 and causing it to deform. This, in turn, causes the two sliding strips 18 to slide apart. When the fixing block 9 and the limiting block 15 slide to a certain position, the limiting block 15 is inserted into the fixing groove 10 under the action of the spring 19, thereby achieving a tight connection between the upper mold shell 1 and the lower mold shell 4. When it is necessary to disassemble the mold, the operator can manually move the lever 12. The lever 12 causes the sliding strip 18 to move outward against the elastic force of the spring 19. At this time, the limiting rod 17 is rotated so that the limiting rod 17 abuts against the limiting groove 13. Without the operator having to hold the lever, the limiting block 15 is disengaged from the fixing groove 10, and the upper mold shell 1 and the lower mold shell 4 can be easily separated. In the process of producing electric poles, the multiple evenly distributed reinforcing ribs 2 fixedly connected to the outer periphery of the upper mold shell 1 and the lower mold shell 4 can effectively enhance the overall structural strength of the mold. When concrete is poured into the mold, the reinforcing rib 2 helps the mold withstand the pressure generated by the concrete, preventing the mold from deforming due to excessive pressure. The clamping ring 3 facilitates the handling and fixing of the mold on the production line. During mold transfer, connecting the clamping ring 3 with hoisting equipment or other handling tools ensures stable mold movement and avoids damage to the mold due to shaking or collision. The rotating track 5 facilitates centrifugal operation of the mold. The limiting protrusion 7 of the lower mold shell 4 abuts against the limiting groove 6 of the upper mold shell 1, reducing the probability of concrete overflow and the frequency of cleaning by workers.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
