[0002] In the production process of reinforced concrete drainage pipes, the demolding stage directly affects production efficiency, product quality, and production costs. Existing molds for reinforced concrete drainage pipe production cannot guarantee that the reinforcing cage placed inside the pouring trench is in a centered position, which can lead to misalignment of the reinforcing cage and result in poor molding quality of the reinforced concrete drainage pipe.

[0003] To address the aforementioned issues, there is an urgent need for innovative designs based on existing reinforced concrete drainage pipe production molds. Utility Model Content

[0004] The purpose of this utility model is to provide a production mold for reinforced concrete drainage pipes to solve the problems mentioned in the background art.

[0006] The inner mold has an inner cavity, and a positioning mechanism is provided inside the inner cavity;

[0007] The top of the base is provided with a vertical moving mechanism;

[0008] The vertical moving mechanism includes a second cylinder. The second cylinder is fixed at the center of the top of the base. A lifting plate is fixed at the output end of the top of the second cylinder. A second guide rod is slidably installed through the side of the lifting plate. The lower end and upper end of the second guide rod are fixedly connected to the top of the base and the bottom of the platform, respectively. A top rod is fixed at the top of the lifting plate. The upper end of the top rod is slidably installed inside the through hole. The through hole is opened on the platform and is located between the inner mold and the outer mold.

[0009] Preferably, the horizontal moving mechanism includes a fixed plate, and fixed plates are fixed on both sides of the top of the platform. A first cylinder is fixedly fixed inside the fixed plate, and the end of the first cylinder is fixedly connected to the outer wall of the outer mold. A first guide rod is slidably installed inside the fixed plate on both sides of the first cylinder, and the end of the first guide rod is fixedly connected to the outer wall of the outer mold.

[0010] Preferably, the positioning mechanism includes a rotating shaft. The rotating shaft is rotatably mounted at the top center and bottom center of the inner cavity via bearings. A cam is fixed to the outer wall of the rotating shaft. The lower end of the rotating shaft passes through the bottom of the inner mold and the interior of the platform, and is fixedly connected to the output end of the top of the servo motor. The outer wall of the servo motor is fixed to the bottom of the platform via a mounting plate. A movable plate is attached to the side of the cam. A positioning rod is fixed to one side of the movable plate away from the cam. The end of the positioning rod is slidably mounted inside a positioning hole, which is located on the side of the inner mold. The end of the positioning rod coincides with the outer side of the inner mold. A spring is movably nested on the outer side of the positioning rod. The two ends of the spring are respectively connected to one side of the movable plate and the inner side of the inner cavity.

This causes the left movable plate to push the two positioning rods on the left to move to the left, while the right movable plate pushes the two positioning rods on the right to move to the right, until the ends of all four positioning rods simultaneously contact the inside of the reinforcing cage, thus positioning the reinforcing cage and ensuring it is centered in the pouring trough, guaranteeing the quality of the formed concrete drainage pipe. The design of six second guide rods facilitates the horizontal lifting and lowering of the lifting plate. During the lifting and lowering process, the six top rods can be simultaneously lifted and lowered, allowing the bottom of the formed concrete drainage pipe to be uniformly pushed upwards, which is beneficial for demolding the formed concrete drainage pipe.

Detailed Implementation

[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] Please see Figure 1-7 This utility model provides a technical solution: a production mold for reinforced concrete drainage pipes, including a base 1, a platform 3 fixed to the top side of the base 1 by a support column 2, an inner mold 4 fixed at the center of the top of the platform 3, two outer molds 5 arranged on the outer side of the inner mold 4, and a horizontal moving mechanism arranged on the outer side of the outer molds 5. The horizontal moving mechanism includes a fixing plate 13, and fixing plates 13 are fixed on both sides of the top of the platform 3. A first cylinder 14 is fixedly fixed inside the fixing plate 13, and the end of the first cylinder 14 is fixedly connected to the outer wall of the outer mold 5. A first guide rod 15 is slidably installed inside the fixing plate 13 on both sides of the first cylinder 14, and the end of the first guide rod 15 is fixedly connected to the outer wall of the outer mold 5.

[0025] The inner mold 4 has an inner cavity 6, and a positioning mechanism is installed inside the inner cavity 6. The positioning mechanism includes a rotating shaft 7. The rotating shaft 7 is rotatably mounted at the top center and bottom center of the inner cavity 6 via bearings. A cam 8 is fixed to the outer wall of the rotating shaft 7. The lower end of the rotating shaft 7 passes through the bottom of the inner mold 4 and the interior of the platform 3, and is fixedly connected to the top output end of the servo motor 9. The outer wall of the servo motor 9 is fixed to the bottom of the platform 3 via a mounting plate. A movable plate 10 is attached to the side of the cam 8. A positioning rod 11 is fixed to one side of the movable plate 10 away from the cam 8. The end of the positioning rod 11 is slidably installed inside the positioning hole 21, and the positioning hole 21 is opened on the side of the inner mold 4. The end coincides with the outer side of the inner mold 4. The outer side of the positioning rod 11 is movably nested with a spring 12. The two ends of the spring 12 are respectively connected to one side of the movable plate 10 and the inner side of the inner cavity 6. The central axes of the rotating shaft 7, cam 8, inner mold 4, outer mold 5 and inner cavity 6 coincide with each other. The movable plate 10, positioning rod 11, spring 12 and positioning hole 21 are symmetrically distributed about the central axis of the cam 8. This ensures that when the rotating shaft 7 drives the cam 8 to rotate, the positioning rods 11 set on the left and right sides of the rotating shaft 7 can move away from each other at the same time, positioning the steel cage inside the pouring groove between the outer mold 5 and the inner mold 4, so that the steel cage is in the center of the pouring groove, ensuring the quality of the formed concrete drainage pipe.

[0026] A vertical moving mechanism is provided on the top of the base 1. The vertical moving mechanism includes a second cylinder 16. The second cylinder 16 is fixed at the center of the top of the base 1. A lifting plate 17 is fixed to the output end of the top of the second cylinder 16. A second guide rod 18 is slidably installed through the side of the lifting plate 17. The lower end and upper end of the second guide rod 18 are fixedly connected to the top of the base 1 and the bottom of the platform 3, respectively. A push rod 19 is fixed to the top of the lifting plate 17. The upper end of the push rod 19 is slidably installed inside the through hole 20. The through hole 20 is opened on the platform 3 and is located between the inner mold 4 and the outer mold 5. There are six guide rods 18, top rods 19, and through holes 20, all distributed at equal angles to the central axis of the lifting plate 17. The central axes of the lifting plate 17, the inner mold 4, and the outer mold 5 are all coincident. A sealing rubber sheet is fixed to the inner side of the through hole 20, and the inner side of the sealing rubber sheet is in contact with the outer side of the top rod 19. The design of six second guide rods 18 is conducive to the horizontal lifting and lowering of the lifting plate 17. During the lifting and lowering process of the lifting plate 17, it can drive the six top rods 19 to lift and lower simultaneously, so that the bottom of the formed concrete drainage pipe can be pushed upward evenly, which is conducive to the demolding of the formed concrete drainage pipe.

[0027] The inner side of the outer mold 5 and the outer side of the inner mold 4 are both provided with an anti-stick coating. The anti-stick coating material can be boron nitride coating, which is conducive to the separation of the outer mold 5 and the inner mold 4 from the formed concrete drainage pipe. The connecting surfaces of the two outer molds 5 are fixed with sealing rubber sheets, and the bottom of the outer mold 5 is fixed with a sealing rubber sheet. Moreover, the bottom of the sealing rubber sheet is in contact with the top of the platform 3 to prevent the concrete liquid inside the pouring groove between the outer mold 5 and the inner mold 4 from flowing out.

[0028] Working principle: When using this reinforced concrete drainage pipe production mold, first place the steel cage inside the pouring trough between the outer mold 5 and the inner mold 4, then start the servo motor 9. The servo motor 9 drives the two cams 8 to rotate through the rotating shaft 7. The two protruding ends of the cams 8 move closer to the two movable plates 10 respectively, pushing the two movable plates 10 to move away from each other. This causes the movable plate 10 on the left to push the two positioning rods 11 on the left to move to the left, while the movable plate 10 on the right pushes the two positioning rods 11 on the right to move to the right, until the ends of the four positioning rods 11 simultaneously contact the inside of the steel cage, completing the positioning of the steel cage, so that the steel cage can be in the center of the pouring trough. At the same time, the four springs 12 are further compressed.

[0029] Then, concrete liquid is injected into the pouring tank. When the concrete liquid is about to reach the top of the inner mold 4, the injection of concrete liquid is stopped. Then, the servo motor 9 is started to rotate in the opposite direction, so that the protruding end of the cam 8 is away from the movable plate 10. Under the elastic force of the four springs 12, the four positioning rods 11 are retracted into the four positioning holes 21, so that the positioning rods 11 will not affect the ejection of the formed concrete drainage pipe.

[0030] After the concrete drainage pipe dries, the two first cylinders 14 are activated to drive the two outer molds 5 to move away from each other, thus separating the outer molds 5 from the outside of the concrete drainage pipe. Then, the second cylinder 16 is activated to push the lifting plate 17 and the six top rods 19 upward to lift the concrete drainage pipe. Finally, a crane is used to move it away, thus separating the concrete drainage pipe from the inner mold 4.

[0031] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
