Description

Technical Field

[0001] This utility model relates to the field of railway sleeper demolding technology, and more specifically, to a demolding device for railway sleeper production. Background Technology

[0002] With the rapid development of rail transit, people's travel methods have undergone tremendous changes. Rail transit, with its convenience and efficiency, has greatly transformed people's lives, making travel easier and significantly saving time, becoming an indispensable part of the modern urban transportation system. In the construction of rail transit, the installation of sleepers is crucial. Sleepers are like the "foundation" of the track, providing a solid foundation for the subsequent laying of rails and ensuring the smooth and safe operation of trains. Currently, sleeper production mostly uses molding molds combined with concrete pouring. However, existing methods have significant drawbacks in the demolding process. Demolding is usually done by flipping the mold, but after the mold is flipped, the formed sleepers often stick to the inner wall of the mold. This phenomenon makes the demolding process extremely difficult, requiring a lot of manpower and time to deal with the adhesion problem, and may even damage the sleepers due to forced demolding, affecting their quality. Moreover, the difficulty in demolding directly leads to delays in the entire sleeper production process, failing to meet the needs of rapid rail transit construction, and potentially adversely affecting the overall project schedule. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a demolding device for railway sleeper production, which has the advantage of facilitating the demolding of railway sleepers.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a demolding device for railway sleeper production, comprising a support platform, a lower mold fixedly mounted on the top of the support platform, an ejector plate movably mounted inside the lower mold, a threaded sleeve fixedly mounted on the top of the ejector plate, a box fixedly mounted inside the support platform, a threaded rod threadedly connected inside the threaded sleeve, one end of the threaded rod penetrating the interior of the box, a driven gear fixedly mounted on the bottom of the threaded rod, a fixed box fixedly mounted between the support platform and the box, a motor fixedly mounted on the top of the box, a drive gear fixedly mounted on the output end of the motor, and the drive gear and the driven gear meshing.

[0005] As a preferred embodiment of this utility model, a support frame is fixedly installed on the top of the support platform, a limit post is fixedly installed on the top of the lower mold, an upper mold is movably installed on the outer surface of the four limit posts, a first cylinder is fixedly installed at the bottom inside the support frame, and the output end of the first cylinder is fixedly connected to the upper mold, a fixing block is fixedly installed on the top of the support platform, a second cylinder is fixedly installed on the inner side of the fixing block, and a push plate is fixedly installed at the output end of the second cylinder.

[0006] As a preferred embodiment of this utility model, columns are fixedly installed around the bottom of the support platform, and a base is fixedly installed at the bottom of the columns.

[0007] As a preferred embodiment of this utility model, a limiting hole is provided inside the lower mold, and a limiting block is movably installed inside the limiting hole, with the top of the limiting block fixedly connected to the bottom of the upper mold.

[0008] As a preferred embodiment of this utility model, a support cover is movably mounted on the outer surface of the motor, and a support column is fixedly installed between the support cover and the housing.

[0009] As a preferred embodiment of this utility model, the outer surface of the support cover is provided with heat dissipation holes, and the heat dissipation holes are arranged in a circular array.

[0010] As a preferred embodiment of this utility model, the inner diameter of the limiting hole is equal to the outer diameter of the heat dissipation hole, and the interior of the limiting hole has a smooth surface design.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Compared with traditional devices, this utility model can trigger a series of continuous actions simply by starting the motor. It is easy and quick to operate, significantly improving production efficiency and reducing manual operation time and error rate. Regarding transmission stability, the meshing design of the drive gear and driven gear ensures the accuracy and smoothness of power transmission, allowing the threaded rod to rotate stably. The support platform and the housing are reinforced with a fixed box to enhance structural rigidity, effectively resisting vibration and stress during transmission, ensuring reliable operation of the entire transmission system, and reducing the probability of failure. For demolding, the rotation of the threaded rod is converted into linear motion by the threaded sleeve, pushing the ejector plate upwards smoothly. Its top evenly acts on the bottom of the sleeper, smoothly ejecting the sleeper from the lower mold, preventing sleeper damage, ensuring product quality, improving the finished product qualification rate, and bringing better economic benefits to the enterprise.

[0012] 2. Compared with traditional devices, this utility model uses a support platform as its foundation, with the support frame providing a stable installation position, ensuring the structural stability of the entire device and laying the foundation for the precise operation of subsequent components. The first cylinder at the bottom of the support frame acts as the core for controlling the lifting and lowering of the upper mold. Together with the four limiting columns at the top of the lower mold, it can precisely guide the movement of the upper mold, achieving precise mold closing between the lower and upper molds. This greatly improves the molding quality of the sleeper, reduces defects caused by inaccurate mold closing, and lowers production costs. The output end of the first cylinder is fixedly connected to the upper mold, and the opening and closing of the upper mold can be easily achieved by extending and retracting the cylinder. The operation is convenient and efficient, saving manpower and time, and improving production efficiency. In addition, the demolding assistance structure composed of the second cylinder and the push plate on the inner side of the fixed block at the top of the support platform can assist in the smooth ejection of the sleeper during demolding, preventing the sleeper from getting stuck in the mold, further ensuring the continuity and stability of production, and improving overall production efficiency.

[0015] 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.

[0016] like Figures 1 to 7 As shown, this utility model provides a demolding device for railway sleeper production, including a support platform 1, a lower mold 3 fixedly installed on the top of the support platform 1, an ejector plate 16 movably installed inside the lower mold 3, a threaded sleeve 15 fixedly installed on the top of the ejector plate 16, a box 6 fixedly installed inside the support platform 1, a threaded rod 14 threadedly connected inside the threaded sleeve 15, one end of the threaded rod 14 penetrating the inside of the box 6, a driven gear 17 fixedly installed at the bottom of the threaded rod 14, a fixed box 13 fixedly installed between the support platform 1 and the box 6, a motor 19 fixedly installed on the top of the box 6, a drive gear 18 fixedly installed at the output end of the motor 19, and the drive gear 18 meshes with the driven gear 17.

[0017] When the sleeper meets the demolding conditions, the operator starts the motor 19 fixed to the top of the box 6. The output of the motor 19 drives the drive gear 18 to rotate at high speed. Since the drive gear 18 meshes with the driven gear 17, the driven gear 17 rotates synchronously and drives the threaded rod 14 to rotate inside the box 6. The rotation of the threaded rod 14 is converted into linear motion through the threaded sleeve 15, which pushes the ejector plate 16 to move upward along the inside of the lower mold 3. During this process, the support platform 1 and the box 6 are reinforced with the structural rigidity through the fixed box 13 to ensure the stable operation of the transmission system. The ejector plate 16 continues to rise, and its top directly acts on the bottom of the sleeper, smoothly ejecting the sleeper from the lower mold 3 and realizing the demolding action.

[0018] The motor 19, fixed to the top of the box 6, is started. The output of the motor 19 quickly drives the drive gear 18 to rotate at high speed. Because the drive gear 18 and the driven gear 17 are tightly meshed, the driven gear 17 rotates synchronously, thereby driving the threaded rod 14 to rotate stably within the box 6. When the threaded rod 14 rotates, the rotational force is converted into a linear upward thrust through the threaded sleeve 15, which is threaded with it. This pushes the ejector plate 16 to move precisely upward along the interior of the lower mold 3. The support platform 1 and the box 6 are reinforced by the fixed box 13, ensuring the smooth operation of the transmission system. Finally, the ejector plate 16 smoothly ejects the sleeper, efficiently completing the demolding. Compared with traditional devices, this device can trigger a series of continuous actions simply by starting the motor 19, making it simple and quick to operate and highly efficient. This system significantly improves production efficiency, reduces manual operation time and error rate. Regarding transmission stability, the meshing design of the drive gear 18 and driven gear 17 ensures accurate and smooth power transmission, allowing the threaded rod 14 to rotate stably. The support platform 1 and the housing 6 are reinforced by a fixed box 13, effectively resisting vibration and stress during transmission, ensuring reliable operation of the entire transmission system, and reducing the probability of failure. For demolding, the rotation of the threaded rod 14 is converted into linear motion by the threaded sleeve 15, pushing the ejector plate 16 to rise smoothly. Its top evenly acts on the bottom of the sleeper, smoothly ejecting the sleeper from the lower mold 3, preventing sleeper damage, ensuring product quality, improving the finished product qualification rate, and bringing better economic benefits to the enterprise.

The support platform 1 is fixedly mounted with a fixing block 9, the fixing block 9 is fixedly mounted with a second cylinder 10 on the inner side, and the output end of the second cylinder 10 is fixedly mounted with a push plate 11.

[0020] The support platform 1 serves as the foundation of the entire device. The support frame 2, which is fixedly installed on top of the platform, provides a stable mounting position for other components. The first cylinder 4, located at the bottom inside the support frame 2, is the core component for controlling the lifting and lowering of the upper mold 12. The four limiting posts 5 fixed on the top of the lower mold 3 can accurately guide the movement direction of the upper mold 12, ensuring accurate mold closing between the lower mold 3 and the upper mold 12 and guaranteeing the quality of the sleeper molding. The output end of the first cylinder 4 is fixedly connected to the upper mold 12. The opening and closing of the upper mold 12 can be easily achieved by extending and retracting the cylinder, making the operation convenient and efficient. In addition, the second cylinder 10 installed inside the fixed block 9 on the top of the support platform 1 and its output push plate 11 constitute a demolding assistance structure. When the sleeper needs to be demolded, the second cylinder 10 pushes the push plate 11, which can help to smoothly push the sleeper out of the mold.

[0021] The support platform 1 serves as the foundation of the entire sleeper production demolding device. The support frame 2 fixed on it provides a stable mounting framework for other components. The first cylinder 4 at the bottom of the support frame 2 is crucial for controlling the lifting and lowering of the upper mold 12. The four limiting posts 5 at the top of the lower mold 3 precisely guide the movement of the upper mold 12, ensuring accurate mold closing between the lower mold 3 and the upper mold 12, thus effectively guaranteeing the quality of sleeper molding. The output end of the first cylinder 4 is connected to the upper mold 12; the extension and retraction of the cylinder easily opens and closes the upper mold 12, making operation very convenient. Furthermore, the second cylinder 10 and push plate 11 inside the fixed block 9 at the top of the support platform 1 constitute a demolding assistance structure. During sleeper molding and demolding, the second cylinder 10 pushes the push plate 11, assisting in the smooth ejection of the sleeper. Compared to traditional devices, this device, based on the support platform 1 and with the support frame 2 providing a stable mounting position, ensures the structural stability of the entire device. To lay the foundation for the precise operation of subsequent components, the first cylinder 4 at the bottom of the support frame 2 serves as the core for controlling the lifting and lowering of the upper mold 12. Together with the four limiting posts 5 on the top of the lower mold 3, it can precisely guide the movement of the upper mold 12, achieving precise mold closing between the lower mold 3 and the upper mold 12. This greatly improves the molding quality of the sleeper, reduces defects caused by inaccurate mold closing, and lowers production costs. The output end of the first cylinder 4 is fixedly connected to the upper mold 12. The opening and closing of the upper mold 12 can be easily achieved by extending and retracting the cylinder. The operation is convenient and efficient, saving manpower and time, and improving production efficiency. In addition, the demolding assistance structure composed of the second cylinder 10 and the push plate 11 on the inner side of the fixing block 9 on the top of the support platform 1 can assist in the smooth ejection of the sleeper during the demolding process, preventing the sleeper from getting stuck in the mold. This further ensures the continuity and stability of production and improves overall production efficiency.

[0022] Among them, the support platform 1 has columns 7 fixedly installed around its bottom, and the bottom of the columns 7 has a base 8 fixedly installed.

[0023] Since the support platform 1 has columns 7 fixedly installed around its bottom, and the bottom of the columns 7 has a base 8 fixedly installed, the cooperation between the columns 7 and the base 8 facilitates stable support for the support platform 1, ensuring the stability of the support platform 1 during the process.

[0024] The lower mold 3 has a limiting hole 23 inside, and a limiting block 22 is movably installed inside the limiting hole 23. The top of the limiting block 22 is fixedly connected to the bottom of the upper mold 12.

[0025] Since the top of the limiting block 22 is fixedly connected to the bottom of the upper mold 12, the cooperation between the limiting hole 23 and the limiting block 22 facilitates the limiting and fixing of the upper mold 12 inside the lower mold 3, ensuring the stability of the upper mold 12 during use.

[0026] Among them, a support cover 21 is movably installed on the outer surface of the motor 19, and a support column 20 is fixedly installed between the support cover 21 and the box 6.

[0027] Since the support column 20 is fixedly installed between the support cover 21 and the box 6, the cooperation between the support cover 21 and the support column 20 facilitates stable support for the motor 19, reduces the shaking of the motor 19 during use, and improves the efficiency of the motor 19.

[0028] The outer surface of the support cover 21 is provided with heat dissipation holes 24, and the heat dissipation holes 24 are arranged in a circular array.

[0029] Since the outer surface of the support cover 21 has heat dissipation holes 24, and the heat dissipation holes 24 are arranged in a circular array, it is convenient to dissipate heat from the motor 19 in a timely manner, ensuring that the temperature of the motor 19 is stable during use and extending the service life of the motor 19.

[0030] The inner diameter of the limiting hole 23 is equal to the outer diameter of the heat dissipation hole 24, and the interior of the limiting hole 23 has a smooth surface design.

[0031] Since the inner diameter of the limiting hole 23 is equal to the outer diameter of the heat dissipation hole 24, and the interior of the limiting hole 23 has a smooth surface design, it facilitates the stability of the heat dissipation hole 24 during its up-and-down movement inside the limiting hole 23, thereby improving the efficiency of the upper mold 12.

[0032] Working principle and usage process of this utility model: When the sleeper meets the demolding conditions, the operator starts the motor 19 fixed to the top of the box 6. The output of the motor 19 drives the drive gear 18 to rotate at high speed. Since the drive gear 18 meshes with the driven gear 17, the driven gear 17 rotates synchronously and drives the threaded rod 14 to rotate inside the box 6. The rotation of the threaded rod 14 is converted into linear motion through the threaded sleeve 15, which pushes the ejector plate 16 to move upward along the inside of the lower mold 3. During this process, the support platform 1 and the box 6 are reinforced with the structural rigidity through the fixed box 13 to ensure the stable operation of the transmission system. The ejector plate 16 continues to rise, and its top directly acts on the bottom of the sleeper, smoothly ejecting the sleeper from the lower mold 3 and realizing the demolding action.

[0033] The support platform 1 serves as the foundation of the entire device. The support frame 2, which is fixedly installed on top of the platform, provides a stable mounting position for other components. The first cylinder 4, located at the bottom inside the support frame 2, is the core component for controlling the lifting and lowering of the upper mold 12. The four limiting posts 5 fixed on the top of the lower mold 3 can accurately guide the movement direction of the upper mold 12, ensuring accurate mold closing between the lower mold 3 and the upper mold 12 and guaranteeing the quality of the sleeper molding. The output end of the first cylinder 4 is fixedly connected to the upper mold 12. The opening and closing of the upper mold 12 can be easily achieved by extending and retracting the cylinder, making the operation convenient and efficient. In addition, the second cylinder 10 installed inside the fixed block 9 on the top of the support platform 1 and its output push plate 11 constitute a demolding assistance structure. When the sleeper needs to be demolded, the second cylinder 10 pushes the push plate 11, which can help to smoothly push the sleeper out of the mold.
