It addresses the problem that existing technologies require using a utility pole mold for mold closure before pouring cement into the mold. However, current utility pole molds suffer from tooth wear, which reduces the fixing effect of the bolts on the two molds. When there are errors in the placement of the upper and lower molds, the shape of the produced utility poles becomes significantly inaccurate, reducing the working efficiency of the mold-closing device. The device includes a worktable, the lower end of which is fixedly connected to four vertical plates. The outer walls of every two vertical plates are rotatably connected to a housing via bearings. The dimensions of two grooves match the corresponding protrusions. Two insert rods movably pass through through holes on the surface of the worktable and are inserted into their corresponding grooves.

Description

Technical Field

[0001] This utility model belongs to the technical field of pole processing, and more specifically, it relates to a mold closing device that can double-fasten pole molds. Background Technology

[0002] In modern power and telecommunications engineering, cement poles are crucial supports for power lines, cables, and other equipment. As an important component of urban and rural infrastructure, their quality and performance directly affect the stable operation of the entire engineering system, as well as people's electricity safety and communication quality.

[0003] Currently, the production of cement poles requires the use of pole molds for assembly before cement is poured into the molds. However, current pole molds simply use bolts to lock the two molds together. After repeated use over a long period, the bolt teeth wear down, which reduces the bolts' fixing effect on the two molds. When there are errors in the placement of the upper and lower molds, it leads to significant errors in the shape of the produced poles, thus reducing the working efficiency of the pole mold assembly equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mold-closing device for double-fastening utility pole molds. This solves the problem that existing technologies require the use of utility pole molds for mold-closing before pouring cement into the mold. However, current utility pole molds only use bolts to lock the two molds together. After repeated use over a long period, the bolt teeth will wear down, which reduces the fixing effect of the bolts on the two molds. When there is an error in the placement of the upper and lower molds, it will result in a large error in the shape of the produced utility pole. This reduces the working efficiency of the mold-closing device for utility pole molds.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold-closing device for double-fastening utility pole molds, comprising a worktable, the lower end of which is fixedly connected to four vertical plates. The outer walls of every two vertical plates are rotatably connected to a housing via bearings. A pivot in the middle of each housing is fixedly connected to one end of two spring-loaded springs, and the other end of each spring-loaded spring is fixedly connected to a corresponding vertical plate. A pivot in the middle of the housing is fixedly connected to one end of a steel cable. The middle of the two steel cables is in contact with corresponding guide wheels. The outer walls of the two guide wheels are rotatably connected to the worktable via bearings. The ends of the two steel cables are fixedly connected to corresponding circular blocks. The surface of the worktable is machined with four grooves, the size of which is slightly smaller than that of the circular blocks. The ends of the steel cables movably pass through the worktable via the corresponding grooves. The upper surfaces of the two circular blocks are fixedly connected to corresponding protrusions, both of which are cylindrical in shape. The size of the two grooves matches that of the corresponding protrusions. Two insert rods movably pass through the surface of the worktable via through holes, and the two insert rods are inserted into the corresponding grooves.

[0006] As a preferred embodiment of this utility model, the upper end of the workbench is fixedly connected to the lower mold, and the upper surface of the lower mold is fixedly connected to four guide rods, which respectively pass through the upper mold via through holes.

[0007] As a preferred technical solution of this utility model, the surface of the upper mold is processed with multiple curved grooves, and rubber pads are installed inside the multiple curved grooves.

[0008] As a preferred embodiment of this utility model, both the lower mold and the upper mold are machined with mold cavities, and sealing rubber gaskets are installed on the outside of both mold cavities.

[0009] As a preferred embodiment of this utility model, threaded blocks are machined on the surfaces of both the lower and upper molds. The surfaces of every two threaded blocks on the same side are threadedly connected to a fixing bolt, and each fixing bolt movably passes through two threaded blocks.

[0010] As a preferred embodiment of this utility model, the surface of the upper mold is machined with a feed inlet.

[0011] This utility model provides a mold closing device that can double-fasten utility pole molds, which has the following beneficial effects:

[0012] 1. This new type of device, consisting of a workbench, vertical plate, housing, spring, steel cable, guide wheel, round block, protrusion, groove, and insert rod, allows for initial mold closing of the utility pole mold. First, the operator inserts the upper end of the guide rod into the corresponding through hole of the upper mold. Then, the lower surface of the upper mold is pressed tightly against the upper surface of the lower mold. Next, the fixing bolts are screwed into the corresponding two threaded blocks to initially fix the upper and lower molds. Then, the operator moves the round block upwards, causing the steel cable below to move out of the housing. At this time, the other end of the steel cable drives the rotating shaft in the middle of the housing to rotate. The rotating shaft drives the spring to rotate, and the round block drives the upper protrusion... The block passes over the upper mold from above, and the steel cable is pressed tightly against the curved groove machined on the upper mold. Rubber pads installed on the surface of the curved groove prevent wear on the steel cable. Then, the protrusion on the round block is inserted into the groove on the worktable. After that, the insert rod is inserted into the worktable, passing through the groove and the protrusion, so that the protrusion is fixed on the worktable. At this time, because the spring always exerts a force on the rotating shaft on the housing in the opposite direction, the steel cable always presses the upper mold tightly. In this way, when the upper mold and the lower mold are closed, the mold can be fixed by the double fastening method of fixing bolts and steel cables, which improves the working efficiency of the pole mold closing equipment.

[0013] 2. By using the lower mold, guide rod, and upper mold, the upper mold can be moved downwards along the guide rod, thereby avoiding large positional errors between the upper mold and the lower mold when the upper mold is placed. This also improves the working efficiency of the pole mold closing equipment. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figures 1 to 4This utility model provides a mold-closing device for double-fastening utility pole molds: It includes a workbench 1, the lower end of which is fixedly connected to four vertical plates 9. The outer walls of every two vertical plates 9 are rotatably connected to a housing 10 via bearings. The housing 10 rotates on the vertical plates 9. A pivot in the middle of each housing 10 is fixedly connected to one end of two springs 11. The springs 11 always apply a counter-rotating force to the pivot in the middle of the housing 10. The other end of each spring 11 is fixedly connected to a corresponding vertical plate 9. The pivot in the middle of the housing 10 is fixedly connected to one end of a steel cable 12. The middle of the two steel cables 12 contacts a corresponding guide wheel 13, which guides the steel cables 12. The outer walls of the two guide wheels 13 are rotatably connected to the workbench 1 via bearings. The workbench 1 rotates, and the ends of the two steel cables 12 are fixedly connected to the corresponding circular blocks 14. The circular blocks 14 drive the steel cables 12 to move. The surface of the workbench 1 is machined with four grooves 16. The size of two grooves 16 is slightly smaller than that of the circular blocks 14, and the circular blocks 14 can be stuck in the grooves 16. The ends of the steel cables 12 pass through the workbench 1 through the corresponding grooves 16. The upper surfaces of the two circular blocks 14 are fixedly connected to the corresponding protrusions 15. The circular blocks 14 drive the protrusions 15 to move. The two protrusions 15 are both cylindrical in shape. The size of the two grooves 16 matches the corresponding protrusions 15, and the protrusions 15 can be inserted into the grooves 16. The surface of the workbench 1 has two insert rods 17 that pass through through holes. The two insert rods 17 are inserted into the corresponding grooves 16, and the insert rods 17 fix the protrusions 15 in the grooves 16. When the pole mold needs to be closed, the operator first inserts the upper end of the guide rod 3 into the corresponding through hole of the upper mold 4, then makes the lower surface of the upper mold 4 tightly against the upper surface of the lower mold 2. Then, the fixing bolt 19 is screwed into the corresponding two threaded blocks 18 to initially fix the upper mold 4 and the lower mold 2. Then, the operator moves the circular block 14 upward, and the circular block 14 drives the steel cable 12 below to move out of the housing 10. At this time, the other end of the steel cable 12 drives the rotating shaft set in the middle of the housing 10 to rotate. The rotating shaft drives the spring 11 to rotate, and the circular block 14 drives the upper protrusion 15 to pass over the upper mold 4 from above, and makes the steel cable 12 tightly against the upper mold. The curved groove 5 processed on the 4th plate is protected from wear by a rubber pad installed on the surface of the curved groove 5. Then, the protrusion 15 on the round block 14 is inserted into the groove 16 on the worktable 1. Then, the insertion rod 17 is inserted into the worktable 1. The insertion rod 17 passes through the groove 16 and the protrusion 15, so that the protrusion 15 is fixed on the worktable 1. At this time, since the spring 11 always gives the rotating shaft on the housing 10 a force to rotate in the opposite direction, the steel cable 12 always presses the upper mold 4. In the above way, when the upper mold 4 and the lower mold 2 are closed, the mold can be fixed by the double fastening method of the fixing bolt 19 and the steel cable 12, which improves the working effect of the pole mold closing equipment.

[0023] The upper end of the workbench 1 is fixedly connected to the lower mold 2. The upper surface of the lower mold 2 is fixedly connected to four guide rods 3. The guide rods 3 enable the upper mold 4 to fit tightly against the lower mold 2 when it descends, thus avoiding errors. The four guide rods 3 pass through the upper mold 4 through through holes.

[0024] The upper mold 4 has multiple grooves 5 machined on its surface. Each groove 5 has a rubber pad installed inside. The grooves 5 and the rubber pads can reduce the wear between the steel cable 12 and the upper mold 4.

[0025] Both the lower mold 2 and the upper mold 4 have mold cavities 7 machined on their surfaces, and sealing rubber gaskets 8 are installed on the outside of both mold cavities 7.

[0026] Both the lower mold 2 and the upper mold 4 have threaded blocks 18 machined on their surfaces. The surfaces of every two threaded blocks 18 on the same side are threadedly connected to a fixing bolt 19. The fixing bolt 19 fixes the two threaded blocks 18 together, so that the upper mold 4 and the lower mold 2 are in close contact. Each fixing bolt 19 moves through the two threaded blocks 18.

[0027] The upper mold 4 has a feed inlet 6 on its surface, which allows concrete to enter the mold cavity 7 from the feed inlet 6.

[0028] The specific usage and function of this embodiment are as follows:

[0029] When using this utility model, if it is necessary to close the pole mold, the operator first inserts the upper end of the guide rod 3 into the corresponding through hole of the upper mold 4, then makes the lower surface of the upper mold 4 tightly against the upper surface of the lower mold 2, and then screws the fixing bolt 19 into the corresponding two threaded blocks 18 to initially fix the upper mold 4 and the lower mold 2. Then the operator moves the circular block 14 upward, and the circular block 14 drives the steel cable 12 below to move out of the housing 10. At this time, the other end of the steel cable 12 drives the rotating shaft set in the middle of the housing 10 to rotate, and the rotating shaft drives the spring 11 to rotate. The circular block 14 drives the upper protrusion 15 to pass over the upper mold 4 from above. The steel cable 12 is pressed tightly against the groove 5 machined on the upper mold 4. Rubber pads installed on the surface of the groove 5 prevent wear on the steel cable 12. Then, the protrusion 15 on the round block 14 is inserted into the groove 16 on the worktable 1. Then, the insertion rod 17 is inserted into the worktable 1. The insertion rod 17 passes through the groove 16 and the protrusion 15, fixing the protrusion 15 on the worktable 1. At this time, since the spring 11 always gives the rotating shaft on the housing 10 a force to rotate in the opposite direction, the steel cable 12 always presses the upper mold 4. Then, concrete is poured into the feed port 6. The concrete is formed in the mold cavity 7 between the upper mold 4 and the lower mold 2, completing the mold closing production of the pole mold.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
