Description

Technical Field

[0001] This utility model relates to the field of turbine runner mold technology, and in particular to a turbine runner mold. Background Technology

[0002] The turbine runner is the core component of a water turbine, generally consisting of blades, an upper crown, and a lower ring. Common types include mixed-flow, axial-flow, and impulse turbines. Its main function is to convert water flow energy into mechanical energy to drive a generator to produce electricity. Its performance directly affects the efficiency, output, and stability of the water turbine. Turbine runner molds are the tools used to manufacture turbine runners. They provide precise shapes and dimensions for component forming, enabling mass production, improving production efficiency, reducing costs, and ensuring the consistency and interchangeability of components.

[0003] In the manufacturing process of turbine runners, compression molding is a commonly used process. However, the traditional turbine runner unloading process after molding has many problems. On the one hand, the traditional unloading method often requires manual intervention, which is not only inefficient, but also prone to damage when the runner is removed from the mold due to human error, affecting product quality and production efficiency. In addition, traditional molds lack effective automated drive components, which cannot realize the automation of the unloading process, increasing labor costs and production cycle.

[0004] Therefore, it is necessary to provide a new turbine runner mold to solve the above-mentioned technical problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5A turbine runner mold includes: a base 1, a hydraulic press body 2 for molding is mounted on the top of the base 1, a mold body 3 is mounted on the top of the base 1, a runner body 4 is placed on the top of the mold body 3, a rotating plate 5 is fixedly connected to the top of the mold body 3, clamping rods 6 are symmetrically mounted on the top of the base 1, an L-shaped rod 7 is fixedly connected to one side of the clamping rods 6, a first driving component for driving the clamping rods 6 to clamp is installed inside the rotating plate 5, a second driving component for driving the rotating plate 5 to move is mounted on the top of the base 1, a slanted rod 61 for unloading is fixedly connected to one side of the base 1, and rubber pads are fixedly connected to the opposite sides of the two clamping rods 6, both clamping rods 6 are arc-shaped.

[0032] It should be noted that the clamping rod 6 has an arc-shaped design and a rubber pad is fixedly connected to the opposite side, which can stably and reliably clamp the mold body 3 while avoiding damage to the mold body 3.

[0033] Please see Figures 1 to 4 The first drive assembly includes an electric push rod 21, a push plate 22, and a sliding column 23. The electric push rod 21 is fixedly connected inside the rotating plate 5, and the push plate 22 is fixedly connected to the output end of the electric push rod 21. The push plate 22 slides inside the rotating plate 5. A first sliding groove 24 is opened on the side of the push plate 22 away from the electric push rod 21. Both L-shaped rods 7 slide inside the first sliding groove 24. The top of both L-shaped rods 7 is fixedly connected to the sliding column 23. A second sliding groove 25 is opened on the side of the push plate 22 away from the base 1. Both sliding columns 23 slide in the second sliding groove 25. A guide groove 26 is opened inside the rotating plate 5. Both sliding columns 23 pass through the second sliding groove 25 and slide in the corresponding guide groove 26. An opening is opened on the side of the rotating plate 5 away from the electric push rod 21. The L-shaped rods 7 enter the first sliding groove 24 through the opening.

[0034] It should be noted that the sliding of the push plate 22 will push the two L-shaped rods 7 and the clamping rods 6 closer to the rotating wheel body 4. The sliding column 23 on the L-shaped rod 7 moves with the L-shaped rod 7, and the sliding column 23 at the top of the L-shaped rod 7 slides in the second sliding groove 25 of the push plate 22 and the guide groove 26 of the rotating plate 5, so that the two sliding columns 23 gradually approach each other along the second sliding groove 25 under the guidance of the obliquely designed guide groove 26, so that the two L-shaped rods 7 approach each other, and the two clamping rods 6 complete the squeezing and clamping of the rotating wheel body 4.

[0035] Please see Figure 2 , Figure 3 and Figure 5The second drive assembly includes: a fixed column 31, a drive motor 32, a threaded rod 33, a threaded sleeve 34, and a support block 35. The fixed column 31 is fixedly connected to the top of the base 1, the drive motor 32 is fixedly connected inside the base 1, the threaded rod 33 is fixedly connected to the output end of the drive motor 32, the threaded sleeve 34 is threadedly connected to the outer wall of the threaded rod 33, the threaded sleeve 34 slides in the fixed column 31, an L-shaped groove 36 is opened on one side of the fixed column 31, the threaded sleeve 34 passes through the L-shaped groove 36 and is fixedly connected to the support block 35, the top of the support block 35 is fixedly connected to the rotating plate 5, and the axes of the fixed column 31, the threaded rod 33, and the threaded sleeve 34 are all located on the same axis.

[0036] It should be noted that the threaded sleeve 34 passes through the L-shaped groove 36 and is fixedly connected to the support block 35. The top of the support block 35 is fixedly connected to the rotating plate 5. Therefore, the rotation of the threaded rod 33 will cause the threaded sleeve 34 to move linearly along the L-shaped groove 36 in the fixed column 31. Then, the rotating plate 5 will be driven to rise through the support block 35. When the threaded sleeve 34 reaches the top of the L-shaped groove 36, the L-shaped groove 36 will no longer restrict the rotation of the threaded sleeve 34. Thus, the threaded sleeve 34 and the support plate will follow the threaded rod 33 to make circular motion in the L-shaped groove 36, so that the rotating plate 5 drives the L-shaped rod 7 and then drives the rotating wheel body 4 to rotate above the inclined rod 61.

[0037] The working principle of the turbine runner mold provided by this utility model is as follows:

[0038] Compression molding stage:

[0039] The material to be formed is placed in the mold body 3, the hydraulic press body 2 is started, the hydraulic press body 2 applies pressure to the mold body 3, so that the material completes the molding process in the mold body 3, and the roller body 4 is obtained.

[0040] Clamping phase:

[0041] After the molding is completed, the electric push rod 21 inside the rotating plate 5 is activated. The output end of the electric push rod 21 pushes the push plate 22 to slide inside the rotating plate 5. Since the first groove 24 is opened on the side of the push plate 22 away from the electric push rod 21, the two L-shaped rods 7 slide inside the first groove 24. Therefore, the sliding of the push plate 22 will push the two L-shaped rods 7 and the clamping rod 6 closer to the rotating wheel body 4. The sliding column 23 on the L-shaped rod 7 moves with the L-shaped rod 7, and the sliding column 23 at the top of the L-shaped rod 7 slides in the second groove 25 of the push plate 22 and the guide groove 26 of the rotating plate 5. Under the guidance of the obliquely designed guide groove 26, the two sliding columns 23 gradually approach each other along the second groove 25, so that the two L-shaped rods 7 approach each other. The two clamping rods 6 complete the compression and clamping of the rotating wheel body 4. Since the clamping rod 6 is arc-shaped and has a rubber pad fixedly connected to the opposite side, it can stably and reliably clamp the mold body 3, while avoiding damage to the mold body 3.

[0042] Rotation phase:

[0043] The drive motor 32 in the second drive assembly is started. The drive motor 32 drives the threaded rod 33 to rotate. Since the threaded rod 33 has a threaded sleeve 34 connected to its outer wall and the threaded sleeve 34 slides in the fixed column 31, and an L-shaped groove 36 is opened on one side of the fixed column 31, the threaded sleeve 34 passes through the L-shaped groove 36 and is fixedly connected to the support block 35. The top of the support block 35 is fixedly connected to the rotating plate 5. Therefore, the rotation of the threaded rod 33 will cause the threaded sleeve 34 to move linearly along the L-shaped groove 36 in the fixed column 31. Then, the rotating plate 5 is driven to rise through the support block 35, so that the rotating wheel body 4 rises with the rotating plate 5 and is separated from the mold body 3. This avoids damage caused by uneven force on the rotating wheel body 4 due to manual removal. When the threaded sleeve 34 reaches the top of the L-shaped groove 36 in linear motion, the L-shaped groove 36 no longer restricts the rotation of the threaded sleeve 34. Thus, the threaded sleeve 34 and the support plate follow the threaded rod 33 to make circular motion in the L-shaped groove 36, so that the rotating plate 5 drives the L-shaped rod 7 and then drives the rotating wheel body 4 to rotate above the inclined rod 61.

[0044] Material feeding stage:

[0045] When the mold body 3 rotates above the inclined bar 61, the electric push rod 21 in the first drive assembly is retracted, causing the push plate 22 to slide in the opposite direction, which drives the two L-shaped rods 7 to move in opposite directions, thereby causing the clamping rod 6 to release its grip on the mold body 3. At this time, the formed water turbine runner slides down the inclined bar 61 under the action of gravity, completing the unloading process.
