[0002] Thermal insulation pipe is short for heat-insulated pipeline. It is used for the transportation of liquids, gases and other media. It is used in thermal insulation projects for pipelines in petroleum, chemical, aerospace, military, district heating, central air conditioning, municipal and other industries. In the production process of thermal insulation pipe, in order to extend the service life of the thermal insulation pipe, the thermal insulation pipe is often inserted into the protective pipe and foam glue is filled between the thermal insulation pipe and the protective pipe to ensure that the heat is not easily lost. However, when assembling the thermal insulation pipe and the protective pipe, it is often necessary to manually install a collar on the surface of the thermal insulation pipe so that the thermal insulation pipe is centered in the inner cavity of the protective pipe.

[0003] The existing technology has the following problems: 1. Existing molds for producing thermal insulation pipes have a large size due to the slow water cooling efficiency during use; 2. In the process of using existing molds for producing thermal insulation pipes, the assembly efficiency of thermal insulation pipes is low because the installation of barrier rings is often required during the assembly and filling of the thermal insulation pipes.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A mold for producing thermal insulation pipes includes a base, a first electric telescopic rod is fixedly connected to the center of the inner cavity of the base, and a production chamber is fixedly connected to the output end of the first electric telescopic rod, and the bottom of the production chamber is slidably connected to the top of the base. A feeding funnel is fixedly connected to one end of the top of the production chamber, and a motor is fixedly connected to one side of the outer wall of the production chamber. A discharge port is opened at the end of the outer wall of the production chamber away from the motor. An extrusion roller is fixedly connected to the output end of the motor, and the outer wall of the extrusion roller is rotatably connected to the inner wall of the production chamber. The top of the base is fixedly connected to a shaping chamber at the end away from the production chamber, and an insulation pipe is slidably connected to the bottom of the inner cavity of the shaping chamber, while a binding assembly is provided on one side of the outer wall of the shaping chamber.

[0006] A further improvement of the present invention is that the binding assembly includes a binding chamber fixedly connected to one side of the outer wall of the shaping chamber, and a storage groove is provided at one end of the inner cavity of the binding chamber. A second electric telescopic rod is fixedly connected to the end of the inner cavity of the binding chamber away from the storage groove. A first electric telescopic frame is fixedly connected to the output end of the second electric telescopic rod, and the outer wall of the first electric telescopic frame is slidably connected to the inner cavity of the binding chamber.

[0007] A further improvement of the present invention is that: each of the output ends of the first electric telescopic frame is rotatably connected to an electric rotating shaft, and each of the output ends of the electric rotating shaft is fixedly connected to a second electric telescopic frame; each of the output ends of the second electric telescopic frame is fixedly connected to a clamping block, and a gathering strap is clamped between the clamping blocks; a plurality of blocking blocks are fixedly connected to the outer wall of the gathering strap, and the side of the outer wall of the gathering strap away from the blocking block is in contact with the outer wall of the insulation pipe.

[0008] A further improvement of the present invention is that: a drain pipe is fixedly connected to one end of the bottom of the shaping chamber, and a water storage chamber is fixedly connected to one end of the drain pipe; a water inlet pipe is fixedly connected to the top of one side of the outer wall of the water storage chamber; a water pump is fixedly connected to the side of the outer wall of the water storage chamber near the water inlet pipe; a double-ended water pipe is fixedly connected to the output end of the water pump; and one end of the double-ended water pipe is fixedly connected to the inner cavity of the shaping chamber.

[0009] A further improvement of this utility model is that: the inner cavity of the water storage tank is fixedly connected with a number of heat-conducting pipes, and one end of the heat-conducting pipe is fixedly connected with a heat-conducting sheet.

[0010] A further improvement of this utility model is that a cooling chamber is fixedly connected to the outer wall of the water storage tank on the side away from the water inlet pipe, and a fan is fixedly connected to one side of the outer wall of the cooling chamber.

[0011] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a mold for producing thermal insulation pipes. The water is drained back into the water storage tank through a drain pipe to form a water circulation. In order to cool the water temperature quickly, several heat-conducting pipes are set in the inner cavity of the water storage tank. The heat-conducting pipes absorb the temperature of the water and send the heat to a cooling chamber set on the outer wall of the water storage tank away from the water inlet pipe through a heat-conducting plate set at one end. By activating a fan set on the outer wall of the cooling chamber, the heat-conducting plate is cooled. This further solves the problem that the traditional mold for producing thermal insulation pipes has a large device size due to the slow water cooling heat dissipation efficiency during use.

[0012] 2. This utility model provides a mold for producing thermal insulation pipes. By activating the electric rotating shaft between the first and second electric telescopic frames, the second electric telescopic frame rotates around the output end of the first electric telescopic frame, causing the two ends of the gathering tape held by the second electric telescopic frame to be attached to the outer wall of the thermal insulation pipe. Since the contact surfaces between the gathering tape and the thermal insulation pipe are provided with spaced rubber tubes, this further solves the problem of low assembly efficiency of thermal insulation pipes during the use of traditional molds for producing thermal insulation pipes, which often require manual installation of barrier rings when assembling and filling the thermal insulation pipes.

[0015] The present invention will be further described in detail below with reference to embodiments: like Figures 1-5As shown, this utility model provides a mold for producing thermal insulation pipes, including a base 1. A first electric telescopic rod 2 (the electric telescopic rod mentioned in the text is prior art) is fixedly connected to the center of the inner cavity of the base 1. The output end of the first electric telescopic rod 2 is fixedly connected to a production chamber 3, and the bottom of the production chamber 3 is slidably connected to the top of the base 1. A feeding funnel 4 is fixedly connected to one end of the top of the production chamber 3, and a motor 5 is fixedly connected to one side of the outer wall of the production chamber 3. A discharge port 6 is opened at the end of the outer wall of the production chamber 3 away from the motor 5. An extrusion roller 7 is fixedly connected to the output end of the motor 5, and the outer wall of the extrusion roller 7 is rotatably connected to the inner wall of the production chamber 3. A shaping chamber 8 is fixedly connected to the top of the base 1 away from the production chamber 3, and the bottom of the inner cavity of the shaping chamber 8 is slidably connected to... A heat insulation pipe 9 is connected to the outer wall of the shaping chamber 8, and a binding assembly is provided on one side of the outer wall. A drain pipe 19 is fixedly connected to one end of the bottom of the shaping chamber 8, and a water storage tank 20 is fixedly connected to one end of the drain pipe 19. A water inlet pipe 21 is fixedly connected to the top of one side of the outer wall of the water storage tank 20, and a water pump 22 is fixedly connected to the side of the outer wall of the water storage tank 20 near the water inlet pipe 21. A double-ended water pipe 23 is fixedly connected to the output end of the water pump 22, and one end of the double-ended water pipe 23 is fixedly connected to the inner cavity of the shaping chamber 8. Several heat-conducting pipes 24 are fixedly connected to the inner cavity of the water storage tank 20, and a heat-conducting plate 25 is fixedly connected to one end of the heat-conducting pipe 24. A cooling chamber 26 is fixedly connected to the side of the outer wall of the water storage tank 20 away from the water inlet pipe 21, and a fan 27 is fixedly connected to one side of the outer wall of the cooling chamber 26.

[0016] During operation, the first electric telescopic rod 2, located at the center of the inner cavity of the base 1, is activated, causing the production chamber 3 at the output end to slide on top of the base 1. This causes the discharge port 6, located at the center of one side of the outer wall of the production chamber 3, to embed into one side of the outer wall of the shaping chamber 8. At this time, raw materials are poured in through the feed funnel 4 at the top of the production chamber 3, and the heating wire inside the production chamber 3 is activated to melt the raw materials. Subsequently, the motor 5, located on the side of the outer wall of the production chamber 3 away from the discharge port 6, is activated, causing the motor 5 to drive the extrusion roller 7 at the output end to extrude and convey the raw materials, which are then discharged into the shaping chamber 8 through the discharge port 6. At this time, water is injected into the water storage tank 20 through the water inlet pipe 21. The water pump 22 installed on one side of the outer wall of the water storage tank 20 is started, so that the water is discharged into the shaping tank 8 through the double-headed water pipe 23 installed at the output end of the water pump 22. The insulation pipe 9 entering the shaping tank 8 is cooled and shaped. When the insulation pipe 9 is shaped and continues to move through the traction device, the first electric telescopic rod 2 is started again, and the production tank 3 is reset, so that the discharge port 6 is away from the shaping tank 8. This avoids the insulation pipe 9 squeezed out of the discharge port 6 from not being completely cooled, causing some residue to adhere to the feed port of the shaping tank 8, which would cause the feed port to be blocked. It should be further explained that, since a drain pipe 19 is provided at one end of the bottom of the shaping chamber 8, and one end of the drain pipe 19 is connected to the top of the water storage chamber 20, the cold water entering the shaping chamber 8 cools the insulation pipe 9 and is then discharged back into the water storage chamber 20 through the drain pipe 19, forming a water circulation. In order to cool the water temperature quickly, several heat-conducting pipes 24 are installed in the inner cavity of the water storage chamber 20. The heat-conducting pipes 24 absorb the temperature in the water and send the heat to the cooling chamber 26 located on the outer wall of the water storage chamber 20 away from the water inlet pipe 21 through the heat-conducting plate 25 at one end. By starting the fan 27 located on the outer wall of the cooling chamber 26, the heat-conducting plate 25 is cooled, thereby achieving the purpose of cooling the water in the water storage chamber 20. This further solves the problem that the traditional mold for producing insulation pipe 9 has a large device size due to the slow heat dissipation efficiency of water cooling during use.

[0017] The binding assembly includes a binding chamber 10 fixedly connected to one side of the outer wall of the shaping chamber 8. One end of the inner cavity of the binding chamber 10 is provided with a storage groove 11. A second electric telescopic rod 12 is fixedly connected to the end of the inner cavity of the binding chamber 10 away from the storage groove 11. A first electric telescopic frame 13 is fixedly connected to the output end of the second electric telescopic rod 12. The outer wall of the first electric telescopic frame 13 is slidably connected to the inner cavity of the binding chamber 10. Electric rotating shafts 14 are rotatably connected to the output ends of the first electric telescopic frame 13. A second electric telescopic frame 15 is fixedly connected to the output end of the second electric telescopic frame 15. Clamping blocks 16 are fixedly connected to the output ends of the second electric telescopic frame 15. A gathering strap 17 is clamped between the clamping blocks 16. A plurality of blocking blocks 18 are fixedly connected to the outer wall of the gathering strap 17. The side of the outer wall of the gathering strap 17 away from the blocking blocks 18 is in contact with the outer wall of the insulation pipe 9.

[0018] During operation, a binding chamber 10 is installed on one side of the outer wall of the shaping chamber 8. When the shaped insulation tube 9 enters the binding chamber 10, the gathering strap 17 is placed into the storage slot 11 at one end of the top of the binding chamber 10. By activating the second electric telescopic rod 12 located at the end of the inner cavity of the binding chamber 10 away from the storage slot 11, the second electric telescopic rod 12 pushes the first electric telescopic frame 13 (the electric telescopic frame mentioned in the text is prior art) located at the output end, moving it within the inner cavity of the binding chamber 10, and positioning the first electric telescopic frame 13 in a certain position. The top of the gathering strap 17 is placed in the storage slot 11. At this time, the first electric telescopic frame 13 is activated, and the second electric telescopic frame 15 at its output end is brought close to both sides of the gathering strap 17. The second electric telescopic frame 15 is activated to clamp the gathering strap 17. Then, the second electric telescopic frame 15 is activated again to push the gathering strap 17 down and make the gathering strap 17 free from the restriction of the storage slot 11. At this time, the center of the bottom of the gathering strap 17 is at the center of the top of the outer wall of the insulation tube 9 and is in contact with the outer wall of the insulation tube 9. Then, the first electric telescopic frame is activated. An electric rotating shaft 14 is provided between the first electric telescopic frame 13 and the second electric telescopic frame 15, causing the second electric telescopic frame 15 to rotate about the output end of the first electric telescopic frame 13 as the center. This causes the two ends of the gathering strap 17 held by the second electric telescopic frame 15 to adhere to the outer wall of the insulation pipe 9. Because the surfaces of the gathering strap 17 and the insulation pipe 9 are provided with spaced-apart rubber tubes, the gathering strap 17 adheres firmly to the surface of the insulation pipe 9 when it is attached. Furthermore, because the outer wall of the gathering strap 17 is provided with several barrier blocks 18... Furthermore, the surface of the barrier block 18 is smooth and curved, so when the insulation pipe 9 and the binding tape 17 are inserted into the outer pipe, the smooth curved surface of the barrier block 18 reduces friction with the inner wall of the outer pipe, and at the same time, it ensures that the insulation pipe 9 is in the center of the inner cavity of the outer pipe, which facilitates the subsequent filling of insulation foam between the outer pipe and the insulation pipe 9. This further solves the problem that the traditional molds used in the production of insulation pipe 9 often require manual installation of barrier rings during the assembly and filling of insulation pipe 9, resulting in low assembly efficiency of insulation pipe 9.

[0019] The working principle of the mold used in the production of this thermal insulation pipe will be explained in detail below.

[0020] like Figures 1-5As shown, by activating the first electric telescopic rod 2 located at the center of the inner cavity of the base 1, the production chamber 3 located at the output end slides on the top of the base 1, and the discharge port 6 located at the center of one side of the outer wall of the production chamber 3 is embedded into one side of the outer wall of the shaping chamber 8. At this time, the raw material is poured in through the feed funnel 4 located at the top of the production chamber 3, and the electric heating wire located in the inner cavity of the production chamber 3 is activated to melt the raw material. Subsequently, the motor 5 located on the side of the outer wall of the production chamber 3 away from the discharge port 6 is activated, and the motor 5 drives the extrusion roller located at the output end. Shaft 7 extrudes and conveys the raw materials, discharging them into the shaping chamber 8 through discharge port 6. Simultaneously, water is injected into the water storage tank 20 through inlet pipe 21. The water pump 22, located on one side of the outer wall of the water storage tank 20, is activated, causing water to flow into the shaping chamber 8 through a double-ended water pipe 23 at the pump's output end. This cools and shapes the insulation pipe 9 entering the shaping chamber 8. Once the insulation pipe 9 is shaped and continues to move via a traction device, the first electric telescopic rod 2 is activated again, resetting the production chamber 3 and moving the discharge port 6 away from the shaping chamber 8. To prevent residue from adhering to the feed inlet of the shaping chamber 8 due to incomplete cooling of the insulation pipe 9 squeezed out of the discharge port 6, thus causing blockage, it should be further explained that a drain pipe 19 is installed at one end of the bottom of the shaping chamber 8, and one end of the drain pipe 19 is connected to the top of the water storage tank 20. This allows the cold water entering the shaping chamber 8 to cool the insulation pipe 9 before being drained back into the water storage tank 20 through the drain pipe 19, forming a water circulation. To rapidly cool the water, [further measures are taken] within the water storage tank 20. The cavity is equipped with several heat-conducting pipes 24, which absorb the temperature of the water and send the heat to the cooling chamber 26 located on the outer wall of the water storage tank 20 away from the water inlet pipe 21 through the heat-conducting plate 25 at one end. By activating the fan 27 located on the outer wall of the cooling chamber 26, the heat-conducting plate 25 is cooled, thereby achieving the purpose of cooling the water in the water storage tank 20. This further solves the problem that the traditional mold for producing heat-insulating pipes 9 has a large device size due to the slow heat dissipation efficiency of water cooling during use.

[0021] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
