Description

Technical Field

[0001] This utility model belongs to the field of casting mold technology, specifically relating to a casting mold for wind power components. Background Technology

[0002] Wind turbine component casting molds are indispensable key tools in the manufacturing process of wind turbine generators, specifically designed to precisely shape the complex forms of various critical components. These molds, through the pouring of diverse materials such as concrete, composite materials, or metal alloys within a sealed mold cavity, undergo molding and curing processes to ultimately form parts that meet design requirements. Their core function lies not only in accurately replicating the three-dimensional shape of the parts but also in rigorously ensuring dimensional accuracy, structural strength, and surface quality. Dimensional accuracy directly affects the fit between parts and the stability of the entire turbine's operation; structural strength determines whether parts can withstand long-term loads under extreme climatic conditions; and superior surface quality helps reduce wind resistance, improve weather resistance, and extend the service life of parts. These performance indicators collectively ensure that wind power equipment can operate continuously, stably, and efficiently in complex and ever-changing natural environments, meeting the stringent requirements of the wind power industry for high reliability and low maintenance costs.

[0003] In the use of existing wind turbine component casting molds, a release agent is usually applied to the inner wall of the mold to facilitate demolding of the molded parts. However, the application of the release agent for existing casting molds is still mainly done manually. Since manual operation makes it difficult to ensure the absolute uniformity of the application force, angle and coverage, the release agent often exhibits uneven distribution. In some areas, the coating may be too thin to form an effective isolation layer, or local residue may occur due to accumulation, which can directly cause sticking problems, resulting in surface defects or even structural damage to the molded parts, significantly reducing the product yield. Therefore, the practicality of using wind turbine component casting molds is somewhat lacking. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1:

[0027] Please see Figure 1-4 This utility model provides a casting mold for wind power components, comprising:

[0028] Upper template 1 and lower template 2;

[0029] The movable template 3 is located at the bottom of the upper template 1, and the fixed template 4 is located at the top of the lower template 2. The movable template 3 is located at the top of the fixed template 4, and the bottom of the movable template 3 is provided with a punch 5. The upper end of the fixed template 4 is provided with a cavity that matches the punch 5.

[0030] The pouring channel 6 is set inside the upper template 1. The bottom end of the pouring channel 6 passes through the moving template 3 and the punch 5 in sequence. The bottom end of the moving template 3 is provided with an annular groove, which is located outside the punch 5.

[0031] The material storage ring 7 is set in the annular groove. The bottom end of the material storage ring 7 is provided with multiple fixing plates 8. The bottom end of each fixing plate 8 is rotatably connected to an mounting plate 9. Each mounting plate 9 is provided with a nozzle 10 on one side of its upper end.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the upper end of the lower template 2 is equipped with multiple hydraulic cylinders 11. The hydraulic cylinders 11 are existing technology and will not be described in detail here. The output ends of the multiple hydraulic cylinders 11 are all located at the bottom end of the upper template 1. The multiple hydraulic cylinders 11 can drive the upper template 1 and the moving template 3 to move up and down. This can not only open or close the cavity, but also drive the material storage ring 7 and multiple nozzles 10 to move up and down, adjust their height, and increase the spraying range that the multiple nozzles 10 can spray.

[0033] Specifically, such as Figure 3 As shown, the bottom end of the storage ring 7 is provided with multiple material conveying hoses 12, which are connected to multiple nozzles 10 respectively. The multiple material conveying hoses 12 can deliver the release agent in the storage ring 7 to the multiple nozzles 10 when the nozzles 10 are at different angles. The fixed template 4 located at the bottom end of the annular groove has an annular cavity at its upper end, which can prevent the storage ring 7 and the multiple nozzles 10 from affecting the mold closing of the casting mold.

[0034] Specifically, such as Figure 3 As shown, multiple electric push rods 13 are rotatably connected to the bottom end of the storage ring 7. The electric push rods 13 are existing technology and will not be described in detail here. The output ends of the multiple electric push rods 13 are rotatably connected to the upper ends of multiple mounting plates 9 respectively.

[0035] Its design allows multiple electric push rods 13 to rotate multiple mounting plates 9 upon activation, thereby flexibly adjusting the angles of multiple spray nozzles 10. This enables them to adjust the spraying direction according to the complex curved surface of the mold cavity, effectively covering dead-angle areas, ensuring comprehensive application of the release agent, and preventing sticking to the mold.

[0036] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the annular groove sidewall is provided with a snap-fit ​​groove, and the storage ring 7 is provided with an external toothed ring 14 that is adapted to the snap-fit ​​groove on the outside. The external toothed ring 14 is located in the snap-fit ​​groove and is slidably connected to the sidewall of the snap-fit ​​groove. Through the external toothed ring 14 located in the snap-fit ​​groove, its position can be limited without affecting the rotation of the storage ring 7.

[0037] Specifically, such as Figure 2 and Figure 4 As shown, a drive groove is provided on one side of the moving template 3, and a drive motor 15 is provided in the drive groove. The drive motor 15 is existing technology and will not be described in detail here. The output end of the drive motor 15 is provided with a drive wheel 16 that is adapted to the external gear ring 14. One end of the external gear ring 14 extends into the drive groove and meshes with the drive wheel 16. When the drive motor 15 is started, its output end will drive the drive wheel 16 to rotate, and the drive wheel 16 will drive the external gear ring 14 to rotate, thereby driving the material storage ring 7 and multiple nozzles 10 to rotate, so that the multiple nozzles 10 can evenly spray the demolding agent into the cavity, ensuring the smooth demolding of wind power parts.

[0038] Specifically, such as Figure 2 and Figure 4 As shown, the annular groove has an installation groove, which is arranged in a ring shape. A matching feeding ring 17 is fixed in the installation groove. The bottom end of the feeding ring 17 extends into the storage ring 7 and is slidably connected to the inner wall of the storage ring 7. Both sides of the moving template 3 are provided with feeding pipes 18. One end of each feeding pipe 18 is connected to the upper two sides of the feeding ring 17. The feeding ring 17 and the two feeding pipes 18 located in the storage ring 7 can add release agent or water into the storage ring 7 without affecting the rotation of the storage ring 7.

[0039] See Figure 1-4When using casting molds to mold wind turbine components, a release agent needs to be sprayed onto the inner wall of the mold cavity to ensure smooth removal of the molded components. First, the release agent is added to the feeding ring 17 through the feed pipe 18, and then enters the storage ring 7 through the feeding ring 17. Once in the storage ring 7, the release agent flows through multiple conveying hoses 12 into multiple nozzles 10, and is sprayed onto the inner wall of the mold cavity through the nozzles 10. When adjusting the spray range of the multiple nozzles 10, multiple electric push rods 13 need to be activated. The output ends of multiple electric push rods 13 will drive multiple mounting plates 9 to rotate, and the multiple mounting plates 9 will drive multiple nozzles 10 to rotate. The angle of multiple nozzles 10 can be flexibly adjusted. Then, the drive motor 15 is started, and the output end of the drive motor 15 will drive the drive wheel 16 to rotate. The drive wheel 16 will drive the outer toothed ring 14 and the material storage ring 7 to rotate, thereby driving the multiple nozzles 10 to rotate. This further improves the spray range and uniformity of the multiple nozzles 10, significantly reduces the risk of sticking to the mold, and ensures that the wind power parts can be successfully demolded after casting.

[0042] Upper template 1 and lower template 2;

[0043] The movable template 3 is located at the bottom of the upper template 1, and the fixed template 4 is located at the top of the lower template 2. The movable template 3 is located at the top of the fixed template 4, and the bottom of the movable template 3 is provided with a punch 5. The upper end of the fixed template 4 is provided with a cavity that matches the punch 5.

[0044] The pouring channel 6 is set inside the upper template 1. The bottom end of the pouring channel 6 passes through the moving template 3 and the punch 5 in sequence. The bottom end of the moving template 3 is provided with an annular groove, which is located outside the punch 5.

[0045] The material storage ring 7 is set in the annular groove. The bottom end of the material storage ring 7 is provided with multiple fixing plates 8. The bottom end of each fixing plate 8 is rotatably connected to an mounting plate 9. Each mounting plate 9 is provided with a nozzle 10 on one side of its upper end.

[0046] Specifically, such as Figure 2 As shown, a positioning groove is provided through the bottom of the cavity, and a matching ejector plate 19 is provided in the positioning groove. A cylinder 20 is provided at the upper end of the lower template 2. The cylinder 20 is existing technology and will not be described in detail here. The output end of the cylinder 20 extends into the positioning groove and is located at the bottom of the ejector plate 19. An inclined drainage groove 21 is provided through the side wall of the positioning groove at the bottom of the ejector plate 19.

[0047] With its design, when the cylinder 20 is started, it will drive the ejector plate 19 to move up and down. When the ejector plate 19 moves upward, it will eject the molded wind power parts in the cavity, which will further improve the demolding efficiency of the wind power parts. When the ejector plate 19 moves downward, it will allow excess mold release agent or moisture in the cavity to enter the positioning groove and be discharged through the drainage groove 21.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
