Description

Technical Field

[0001] This utility model relates to the field of railway sleeper mold technology, and more specifically, to a double-block railway sleeper mold. Background Technology

[0002] Railway sleeper molds are key equipment in modern railway construction. Made of high-strength steel and precision-machined and heat-treated, they possess high strength and durability. Sleeper molds allow for precise control of sleeper dimensions and appearance, improving production efficiency. Furthermore, sleeper molds are reusable, reducing sleeper manufacturing costs.

[0003] When manufacturing railway sleeper molds, various factors such as the sleeper's size, shape, and load-bearing capacity must be considered to ensure the mold's strength and stability. Simultaneously, the sleeper molds must be easy to assemble, disassemble, and transport, meeting the needs for convenient production and maintenance. However, most existing sleeper molds adopt an integrated design, which is difficult to process, making manufacturing inconvenient and costly. Utility Model Content

[0004] The main purpose of this utility model is to provide a two-block sleeper mold to solve the problems of inconvenient manufacturing and high manufacturing cost of existing sleeper molds.

[0005] To achieve the above objectives, according to one aspect of the present invention, a double-block sleeper mold is provided, comprising:

[0006] The base has a first groove and a second groove spaced apart along its length.

[0007] A panel assembly comprising multiple panels, the multiple panels surrounding the outer periphery of the upper surface of the base and forming a cavity with the base, at least one of the adjacent panels and the panel and the base being provided with a positioning component, the base and the panel and the adjacent panels being positioned by the positioning component and then connected as a whole by a weld.

[0008] Furthermore, the enclosure assembly includes a first enclosure, a second enclosure, a third enclosure, and a fourth enclosure arranged sequentially along the outer periphery of the upper surface of the base. The first enclosure, the second enclosure, the third enclosure, and the fourth enclosure are positioned by the positioning component and then connected end to end by the weld.

[0009] Furthermore, the first enclosure and the third enclosure extend at least partially along the length direction of the base, the second enclosure and the fourth enclosure extend at least partially along the width direction of the base, and the second enclosure and the fourth enclosure are provided with clearance notches, which are at least used for placing trusses.

[0010] Furthermore, there are multiple clearance notches on both the second and fourth enclosures. Each clearance notch is recessed from the top of the corresponding second and fourth enclosures toward the base. The width of the clearance notch gradually narrows from the top to the bottom of the double-block sleeper mold. The multiple clearance notches on the second enclosure correspond one-to-one with the multiple clearance notches on the fourth enclosure, and the line connecting the corresponding clearance notches on the second and fourth enclosures is parallel to the length direction line of the base.

[0011] Furthermore, both ends of the second enclosure plate have first bent sections, which extend along the length direction of the base and are respectively positioned with the first enclosure plate and the third enclosure plate by the positioning component and then connected by the weld; and / or,

[0012] Both ends of the fourth enclosure have second bent sections. The second bent sections extend along the length of the base and are respectively positioned with the first enclosure and the third enclosure by the positioning component and then connected by the weld.

[0013] Furthermore, the positioning component includes a positioning groove and a positioning protrusion, one of which is disposed on one of the two adjacent enclosure plates, and the other is disposed on the other of the two adjacent enclosure plates.

[0014] Furthermore, along the height direction of the base, the inner wall surface of the cavity is inclined towards the outside of the cavity.

[0015] Furthermore, the first groove and the second groove are spaced apart at both ends of the base along the length direction of the base. Both the first groove and the second groove are recessed towards the bottom of the base. The maximum depth of the first groove is greater than the maximum depth of the second groove. Both the first groove and the second groove have a protrusion on the side closest to each other. The protrusion protrudes from the bottom surface of the inner side of the base and extends along the width direction of the base.

[0016] Furthermore, the first groove and the second groove are connected by a first inclined surface on the side closest to each other. The first inclined surface is located on the side of the opening of the first groove and the opening of the second groove. The protrusion protrudes from the upper surface of the first inclined surface, and the side of the first inclined surface closest to the first groove is lower than the side of the first inclined surface closest to the second groove.

[0017] Furthermore, the bottom of the first groove is provided with a first concave arc surface, and the bottom of the second groove is provided with a second concave arc surface. Along the height direction of the base, the first concave arc surface slopes downward from the opening of the first groove and towards the direction closer to the second groove, and the second concave arc surface slopes downward from the opening of the second groove and towards the direction closer to the first groove.

[0018] Applying the technical solution of this utility model, the double-block sleeper mold consists of a base and a surrounding plate assembly. This modular design gives the double-block sleeper mold clearly defined components in its overall structure, facilitating not only manufacturing and installation but also maintenance. The base and surrounding plate assembly cooperate to form a complete double-block sleeper mold, providing a foundation for sleeper molding. Multiple surrounding plates surround the outer perimeter of the upper surface of the base, forming a cavity. This provides a defined space for pouring sleeper concrete, ensuring that the sleeper can be molded according to the designed shape and size, thereby ensuring the consistency of sleeper specifications. The base has first and second grooves spaced apart along its length, which provides a limiting effect for the poured sleeper, providing a more precise position for subsequent track installation and preventing track deviation. Furthermore, the positioning components ensure that when the surrounding plates are fixed to the base or adjacent surrounding plates using welds, the structural deformation caused by displacement or deviation between the components of the double-block sleeper mold is prevented, ensuring the overall precision and stability of the double-block sleeper mold. Meanwhile, the welded connection method further enhances the structural strength and stability of the double-block sleeper mold, making it less prone to deformation under external forces such as concrete pouring pressure, thus increasing its reliability. Furthermore, the design of using multiple side panels to form the side panel assembly facilitates the manufacturing and transportation of the double-block sleeper mold. Compared to a single-piece side panel, the multi-panel design allows each panel to be manufactured separately, significantly reducing the manufacturing difficulty and cost of the double-block sleeper mold, and also making transportation more convenient. Moreover, the placement of positioning components makes the assembly of the side panels and base more convenient and faster, greatly improving the assembly efficiency of the double-block sleeper mold.

[0034] As mentioned in the background section, railway sleeper molds, as key equipment in modern railway construction, play a vital role. Sleeper molds require high-strength steel and undergo precision machining and heat treatment to achieve high strength and durability. Sleeper molds allow for precise control of sleeper dimensions and appearance, improving production efficiency, and are also reusable, reducing manufacturing costs. When manufacturing sleeper molds, factors such as sleeper size, shape, and load-bearing capacity must be considered to ensure mold strength and stability. Simultaneously, sleeper molds need to be easy to assemble, disassemble, and transport, meeting the convenience requirements of production and maintenance. However, most existing sleeper molds adopt an integrated design, which is difficult to process, inconvenient to manufacture, and has high manufacturing costs. Therefore, this application provides a two-piece sleeper mold that is not only easy to manufacture but also has lower manufacturing costs.

[0035] See Figures 1 to 7As shown, this application provides a double-block sleeper mold 100, which includes a base 10 and a surrounding plate assembly 20.

[0036] The base 10 has a first groove 11 and a second groove 12 spaced apart along its length. The enclosure assembly 20 includes multiple enclosures 21, which surround the outer periphery of the upper surface of the base 10 and form a cavity 22 with the base 10. At least one of the following is provided: a positioning component 23 between two adjacent enclosures 21 and between an enclosure 21 and the base 10. The base 10 and the enclosures 21, as well as two adjacent enclosures 21, are positioned by the positioning component 23 and then connected as a whole by a weld 24.

[0037] In this application, the double-block sleeper mold 100 consists of a base 10 and a surrounding plate assembly 20. This modular design gives the double-block sleeper mold 100 clearly defined components in its overall structure, facilitating both manufacturing and installation as well as maintenance. The base 10 and the surrounding plate assembly 20 cooperate to form a complete double-block sleeper mold 100, providing a foundation for sleeper molding. Multiple surrounding plates 21 surround the outer periphery of the upper surface of the base 10, forming a cavity 22. This provides a defined space for pouring sleeper concrete, ensuring that the sleeper can be molded according to the designed shape and size, thereby ensuring the consistency of sleeper specifications. The base 10 has first grooves 11 and second grooves 12 spaced apart along its length, which allows the poured sleeper to have a limiting function, providing a more precise position for subsequent track installation and preventing track deviation. Furthermore, the positioning component 23 ensures that when the enclosure 21 and the base 10, as well as adjacent enclosures 21, are fixed using welds, structural deformation will not occur due to displacement or deviation between the components of the double-block sleeper mold 100, thus guaranteeing the overall accuracy and stability of the double-block sleeper mold 100. Simultaneously, the connection method of the weld 24 further enhances the structural strength and stability of the double-block sleeper mold 100, making it less prone to deformation under external forces such as concrete pouring pressure, thus making the double-block sleeper mold 100 more reliable. Moreover, the design of using multiple enclosures 21 to form the enclosure assembly 20 facilitates the manufacturing and transportation of the double-block sleeper mold 100. Compared to a single enclosure 21, the combined design of multiple enclosures 21 allows each enclosure 21 to be manufactured separately, significantly reducing the manufacturing difficulty and cost of the double-block sleeper mold 100, and also making transportation more convenient. Furthermore, the positioning component 23 makes the assembly of the enclosure 21 and the base 10 more convenient and quick, greatly improving the assembly efficiency of the double-block sleeper mold 100.

[0038] In other words, by using a double-block sleeper mold 100 composed of a base 10 and multiple surrounding plates 21, this application not only reduces the processing difficulty of the double-block sleeper mold 100, making it easier to manufacture, but also greatly reduces the manufacturing cost of the double-block sleeper mold 100. While providing convenience, it can also save certain production costs, which is conducive to large-scale manufacturing.

[0039] Further, see Figures 1 to 4 As shown, the enclosure assembly 20 includes a first enclosure 211, a second enclosure 212, a third enclosure 213 and a fourth enclosure 214 arranged sequentially along the outer periphery of the upper surface of the base 10. The first enclosure 211, the second enclosure 212, the third enclosure 213 and the fourth enclosure 214 are positioned by the positioning component 23 and then connected end to end by the weld 24 to form a whole.

[0040] Specifically, the cofferdam assembly 20 consists of four cofferdam plates 21 connected end-to-end (i.e., the first cofferdam plate 211, the second cofferdam plate 212, the third cofferdam plate 213, and the fourth cofferdam plate 214). The formed cofferdam assembly 20 is then connected to the base 10, thus forming a complete mold structure (i.e., a double-block sleeper mold 100). The cofferdam assembly 20 is arranged around the outer periphery of the upper surface of the base 10. Each cofferdam plate (i.e., the first cofferdam plate 211, the second cofferdam plate 212, the third cofferdam plate 213, and the fourth cofferdam plate 214) is positioned by the positioning component 23 and then connected end-to-end by welds 24, ensuring the stability of the overall structure of the mold (double-block sleeper mold 100). During operations such as pouring sleeper concrete, the cofferdam plates and the base 10 can withstand significant pressure and impact, preventing deformation or damage and ensuring the quality of the sleeper formed using the double-block sleeper mold 100. The precise setting and connection of each panel in the panel assembly 20 ensures the dimensional accuracy of the internal space of the mold (i.e., cavity 22). The first panel 211, second panel 212, third panel 213, and fourth panel 214, arranged sequentially along the outer periphery of the base 10, are accurately positioned by the positioning component 23. This provides precise forming space for the double-block sleeper, ensuring that when the panel 21 is fixed to the base 10 using welds 24, there will be no positional shift between the structures, guaranteeing structural accuracy and reducing the difficulty of fixing with welds 24. Designing the mold as a combination of the panel assembly 20 and the base 10 facilitates manufacturing and assembly. Each panel 21 of the panel assembly 20 can be manufactured separately and then assembled on-site or in the factory. The use of the positioning component 23 simplifies the assembly process, improves assembly efficiency, and reduces manufacturing difficulty and cost. Simultaneously, this modular design facilitates mold transportation and installation. Furthermore, this structural design of the double-block sleeper mold 100 possesses a certain degree of versatility and adaptability. The size and shape of the base 10 and the surrounding plate assembly 20 can be adjusted according to different sleeper design requirements, or the base 10 and the surrounding plate 21 of different specifications can be replaced to meet the production needs of different types of double-block sleepers, thereby improving the scope and flexibility of mold application.

[0041] It is understandable that, since the double-block sleeper mold 100 of this application is formed by the combination structure of four side panels 21 and a base 10, each side panel 21 of the side panel assembly 20 can be manufactured separately and then assembled on-site or in a factory. However, the assembled double-block sleeper mold 100 can be reused, and since the double-block sleeper mold 100 is generally made of high-strength steel, even if the double-block sleeper mold 100 suffers minor damage, it can be repaired by welding or other methods, greatly saving costs.

[0042] Further, see Figures 1 to 4 , Figure 6As shown, the first enclosure 211 and the third enclosure 213 extend at least partially along the length direction of the base 10, and the second enclosure 212 and the fourth enclosure 214 extend at least partially along the width direction of the base 10. The second enclosure 212 and the fourth enclosure 214 are provided with clearance notches 2121, which are at least used to place the truss 30.

[0043] Specifically, the length direction of the base 10 is... Figure 2 and Figure 6 The length direction shown is the same as the width direction of the base 10. Figure 2 and Figure 3 The width direction is shown in the figure. The first and third side panels 211 and 213 extend at least partially along the length of the base 10, and the second and fourth side panels 212 and 214 extend at least partially along the width of the base 10. This arrangement allows the side panel assembly to fit tightly against the outer periphery of the base 10. This ensures the overall structural stability of the double-block sleeper mold 100, allowing it to better withstand the pressure generated during concrete pouring and other processes during sleeper production, ensuring the mold does not deform and thus guaranteeing the quality of the sleeper's molding. The design of the clearance notch 2121 facilitates the installation of the truss 30, allowing it to be accurately placed in the appropriate position within the mold, preventing positional displacement of the truss 30 during pouring and ensuring the molded sleeper does not meet requirements. The truss 30 plays a crucial role in enhancing the structural strength of the double-block sleeper. The clearance notch 2121 ensures the smooth installation of the truss 30, thereby guaranteeing the structural performance of the sleeper. Because the double-block sleeper mold 100 has a dedicated clearance notch 2121 for placing the truss 30, workers can install the truss 30 into the mold more quickly and accurately during production, reducing installation time and operational difficulty. This helps improve the production efficiency of double-block sleepers and reduce production costs. The clearance notch 2121 does not affect the overall structural function of the enclosure assembly. While ensuring the placement of the truss 30, the enclosure can still effectively form a complete mold space around the base, ensuring the integrity and accuracy of sleeper forming.

[0044] Further, see Figures 1 to 6 As shown, there are multiple clearance notches 2121 on the second enclosure 212 and the fourth enclosure 214. The clearance notches 2121 on the second enclosure 212 and the fourth enclosure 214 are recessed from the top of the corresponding second enclosure 212 and the fourth enclosure 214 toward the direction close to the base 10. The width of the clearance notch 2121 gradually narrows from the top to the bottom of the double-block sleeper mold 100. The multiple clearance notches 2121 on the second enclosure 212 correspond one-to-one with the multiple clearance notches 2121 on the fourth enclosure 214, and the line connecting the corresponding clearance notches 2121 on the second enclosure 212 and the fourth enclosure 214 is parallel to the length direction line of the base 10.

[0045] Specifically, the second and fourth enclosure plates 212 and 214 have multiple clearance notches 2121. This design provides more positioning for the truss 30, making it more stable on the double-block sleeper mold 100 and preventing positional displacement. During actual processing, the number and position of the clearance notches 2121 can be adjusted according to requirements to ensure they meet the needs of the truss 30. The width of the clearance notches 2121 gradually narrows from the top to the bottom of the double-block sleeper mold 100. This design not only allows for a more precise fit between the clearance notches 2121 and the truss 30 but also makes the truss 30 more stable on the double-block sleeper mold 100. The gradually narrowing clearance notches 2121 create a wedge-shaped fit between them, further enhancing the stability of the truss 30 on the double-block sleeper mold 100. Furthermore, the design of the clearance notch 2121, which gradually narrows from the top to the bottom of the double-block sleeper mold 100, facilitates demolding, allowing the cast sleeper to be easily removed from the mold. The multiple clearance notches 2121 on the second side plate 212 correspond one-to-one with the multiple clearance notches 2121 on the fourth side plate 214, and the line connecting the corresponding clearance notches 2121 is parallel to the length line of the base 10. This design not only ensures the symmetry and stability of the mold but also ensures that all parts of the mold work collaboratively during the manufacturing and use of the double-block sleeper mold 100, improving the production quality of the sleeper.

[0046] Further, see Figure 1 , Figure 2 , Figure 4 as well as Figure 5As shown, both ends of the second enclosure 212 have first bent sections 2122. The bent sections extend along the length of the base 10 and are positioned with the first enclosure 211 and the third enclosure 213 respectively by positioning components 23 and then connected by welds 24. Specifically, the first bent sections 2122 not only allow the second enclosure 212 to better fit the shape of the base 10, but also help the operator to connect both ends of the second enclosure 212 to the first enclosure 211 and the third enclosure 213 respectively by welds 24. Because if the first bending section 2122 is not provided at both ends of the second enclosure 212, then welds 24 are required to connect the two corners from the second enclosure 212 to the first enclosure 211 and from the second enclosure 212 to the third enclosure 213. This is not only inconvenient for welding, but also makes the welds 24 at the corners more prone to cracking during the use of the double-block sleeper mold 100, which makes the double-block sleeper mold 100 easy to damage. Therefore, the double-block sleeper mold 100 of this application chooses to provide the first bending section 2122 at both ends of the second enclosure 212.

[0047] Optionally, both ends of the fourth enclosure plate 214 have second bent sections 2141. The second bent sections 2141 extend along the length direction of the base 10 and are respectively positioned with the first enclosure plate 211 and the third enclosure plate 213 by positioning components 23 and then connected by welds 24. Specifically, in this application, the first bent sections 2122 can be provided at both ends of the second enclosure plate 212 alone, or the second bent sections 2141 can be provided at both ends of the fourth enclosure plate 214 alone, or the first bent sections 2122 can be provided at both ends of the second enclosure plate 212 and the second bent sections 2141 can be provided at both ends of the fourth enclosure plate 214 at the same time. However, in order to ensure the structural integrity of the double-block sleeper mold 100, this embodiment shows the case where the first bent sections 2122 are provided at both ends of the second enclosure plate 212 and the second bent sections 2141 are provided at both ends of the fourth enclosure plate 214. The second bending section 2141 not only allows the fourth enclosure plate 214 to better fit the shape of the base 10, but also helps the operator to connect the two ends of the fourth enclosure plate 214 to the first enclosure plate 211 and the third enclosure plate 213 respectively via welds 24. If the second bending section 2141 is not provided at both ends of the fourth enclosure plate 214, welds 24 would be needed at the corners between the fourth enclosure plate 214 and the first enclosure plate 211, and at the corners between the fourth enclosure plate 214 and the third enclosure plate 213. This is not only inconvenient for welding, but also makes the welds 24 at the corners more prone to cracking during the use of the double-block sleeper mold 100, leading to easy damage to the double-block sleeper mold 100. Therefore, the double-block sleeper mold 100 of this application chooses to provide the second bending section 2141 at both ends of the fourth enclosure plate 214.

[0048] Further, see Figure 1 and Figure 4 As shown, the positioning component 23 includes a positioning groove 231 and a positioning protrusion 232. One of the positioning groove 231 and the positioning protrusion 232 is disposed on one of the two adjacent enclosure plates 21, and the other is disposed on the other of the two adjacent enclosure plates 21.

[0049] Specifically, the positioning component 23 consists of a positioning groove 231 and a positioning protrusion 232, and the positioning groove 231 and the positioning protrusion 232 are respectively disposed on one of the two adjacent side panels 21. This arrangement clarifies the distribution of the positioning component 23 on the side panels 21, enabling the positioning groove 231 and the positioning protrusion 232 to accurately engage during the assembly of the double-block sleeper mold 100, achieving precise positioning and effective connection of adjacent side panels 21. The positioning groove 231 and the positioning protrusion 232 can engage with each other to position adjacent side panels 21. Thus, when the adjacent side panels 21 are connected by weld seam 24, the adjacent side panels 21 will not shift in position, resulting in unreliable or inaccurate welding. Therefore, this application uses a positioning component 23 composed of positioning groove 231 and positioning protrusion 232 between adjacent side panels 21. During the manufacturing and use of the double-block sleeper mold 100, this positioning method of the positioning component 23 can ensure the accurate relative position between the side panels 21, improve the assembly accuracy and stability of the double-block sleeper mold 100, and thus guarantee the production quality of the double-block sleeper.

[0050] Further, see Figure 1 , Figure 3 as well as Figure 6 As shown, along the height direction of the base 10, the inner wall surface 221 of the cavity 22 is inclined towards the outside of the cavity 22. Specifically, the height direction of the base 10 is... Figure 3 and Figure 6 The height direction is shown. Since the inner wall surface 221 of cavity 22 is inclined towards the outside of cavity 22, during sleeper production, the inclined inner wall surface 221 reduces the friction between the sleeper and the inner wall surface 221, making it easier for the sleeper to be removed from the double-block sleeper mold 100 after molding, improving production efficiency, and also reducing the risk of damage to the sleeper during demolding. Furthermore, when pouring concrete into cavity 22, the inclined inner wall surface 221 helps the concrete flow and fill better, resulting in a more uniform concrete distribution in all parts of the molded sleeper, thereby improving the quality and performance of the sleeper. To a certain extent, this inclined design of the inner wall surface 221 can also improve the stress condition of the double-block sleeper mold 100 under concrete pressure, enhance the overall structural stability of the double-block sleeper mold 100, and extend the service life of the double-block sleeper mold 100.

[0051] Further, see Figure 1, Figure 2 , Figure 4 , Figure 6 as well as Figure 7 As shown, the first groove 11 and the second groove 12 are spaced apart at both ends of the base 10 along the length direction of the base 10. The first groove 11 and the second groove 12 are both recessed toward the bottom of the base 10. The maximum depth of the first groove 11 is greater than the maximum depth of the second groove 12. The first groove 11 and the second groove 12 are both provided with a protrusion 13 on the side of each other. The protrusion 13 protrudes from the bottom surface of the inner side of the base 10 and extends along the width direction of the base 10.

[0052] Specifically, such as Figure 6 As shown, the maximum depth of the first groove 11 is S1, and the maximum depth of the second groove 12 is S2. The maximum depth of the first groove 11 is greater than the maximum depth of the second groove 12, i.e., S1 > S2. The first groove 11 and the second groove 12 are spaced apart at both ends of the base 10 along the length direction of the base 10. This arrangement provides positions for mounting clips (not shown in the figure) on the formed sleeper, which are used to fix the rail to the sleeper. The maximum depth of the first groove 11 is greater than the maximum depth of the second groove 12. This difference in depth results in a corresponding difference in the height of the protrusion on the top of the formed sleeper. This protrusion can limit the rail and ensure that the relative position between the rail and the sleeper is determined. Both the first groove 11 and the second groove 12 have a protrusion 13 on the side closest to each other. The protrusion 13 protrudes from the bottom surface of the inner side of the base 10 and extends along the width direction of the base 10. The protrusion not only enhances the structural strength of the base 10 but also improves the stability of the double-block sleeper mold 100 under pressure. Meanwhile, the protrusion 13 also gives the cast-in-place sleeper (not shown in the figure) a recess (not shown in the figure) that matches the protrusion 13. The formation of the recess makes the connection between the fastener of the fixed track and the sleeper more stable, and also provides positioning for the installation of the fastener, which can improve the installation efficiency to a certain extent.

[0053] In actual manufacturing of double-block sleepers using the double-block sleeper mold 100 of this application, a truss 30 of suitable size is used to connect two identical double-block sleeper molds 100, ensuring that the length direction of the double-block sleeper mold 100 is parallel to the length direction of the truss 30, and that the truss 30 is fitted into the corresponding clearance notch 2121 of the double-block sleeper mold 100. Then, a baffle (not shown in the figure) is used to surround and fix the two double-block sleeper molds 100 and the truss 30. Next, cement or similar materials are poured. After the double-block sleeper is formed and dried, it is demolded to complete the processing of the double-block sleeper.

[0054] It should be noted that when the two double-block sleeper molds 100 are installed with the truss 30, the ends of the two double-block sleeper molds 100 with the second groove 12 located on them should be close to each other. This will allow the higher protrusions on the processed double-block sleepers to be located at both ends of the double-block sleepers, which will have a better positioning effect on the track.

[0055] Further, see Figure 1 , Figure 2 , Figure 4 , Figure 6 As shown, the first groove 11 and the second groove 12 are connected by a first inclined surface 14 on the side close to each other. The first inclined surface 14 is located on the side of the groove opening of the first groove 11 and the groove opening of the second groove 12. The protrusion 13 protrudes from the upper surface of the first inclined surface 14, and the side of the first inclined surface 14 close to the first groove 11 is lower than the side of the first inclined surface 14 close to the second groove 12.

[0056] Specifically, the first inclined surface 14 ensures that the top of the double-block sleeper, after being cast using the double-block sleeper mold 100 of this application, has an inclined surface that matches the first inclined surface 14. This inclined surface slopes downwards from the end of the double-block sleeper towards its inner side. This prevents trains and other vehicles traveling on the track from derailing after the track is installed on the double-block sleepers, greatly improving safety. Furthermore, the first inclined surface 14 also makes the formed double-block sleepers more conducive to track curvature. During actual installation, simply tilting the double-block sleepers to the desired angle and laying multiple double-block sleepers allows the track to curve in the desired direction.

[0057] Further, see Figure 1 , Figure 2 , Figure 4 , Figure 6As shown, the bottom of the first groove 11 is provided with a first concave arc surface 111, and the bottom of the second groove 12 is provided with a second concave arc surface 121. Along the height direction of the base 10, the first concave arc surface 111 slopes downward from the opening of the first groove 11 and towards the direction closer to the second groove 12, and the second concave arc surface 121 slopes downward from the opening of the second groove 12 and towards the direction closer to the first groove 11. Specifically, the arrangement of the first concave arc surface 111 and the second concave arc surface 121 not only allows the cast double-block sleeper to have a corresponding shape (i.e., the top of the double-block sleeper has a protrusion), but also, since both the first concave arc surface 111 and the second concave arc surface 121 are concave arc surfaces, it is convenient to demold the double-block sleeper during casting. This design can not only improve production efficiency, but also reduce damage to the double-block sleeper mold 100 during demolding, thereby improving the service life of the double-block sleeper mold 100 to a certain extent. Meanwhile, the design of the first concave arc surface 111 and the second concave arc surface 121 improves the stress distribution of the corresponding protrusions on the top of the cast double-block sleeper, making it less prone to damage. Furthermore, along the height direction of the base 10, the first concave arc surface 111 slopes downwards from the opening of the first groove 11 and towards the direction closer to the second groove 12, while the second concave arc surface 121 slopes downwards from the opening of the second groove 12 and towards the direction closer to the first groove 11. This design accelerates fluid flow, allowing cement and other casting materials to flow better towards the bottom of the first groove 11 and the second groove 12 when casting double-block sleepers using the double-block sleeper mold 100 of this application, resulting in a more robust and durable cast double-block sleeper.

[0058] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0059] (1) By providing a positioning component 23 between at least one of the two adjacent side panels 21 and between the side panel 21 and the base 10, it is easier to fix the two adjacent side panels 21 and the side panel 21 and the base 10 by using weld 24, thereby making the double-block sleeper mold 100 of this application easier to manufacture and reducing manufacturing costs to a certain extent.

[0060] (2) By setting multiple clearance gaps 2121 on the second enclosure 212 and the fourth enclosure 214, this application can position the truss 30 during casting, making the processed double-block sleeper more accurate and reliable.

[0061] (3) By tilting the inner wall surface 221 of the cavity 22 toward the outside of the cavity 22, this application facilitates demolding after the double-block sleeper is cast and formed, which greatly improves production efficiency.

[0062] (4) By providing a first bending section 2122 at both ends of the second enclosure 212 and a second bending section 2141 at both ends of the fourth enclosure 214, this application not only facilitates welding of each enclosure 21 by using weld seam 24, but also reduces the welding difficulty.
