Description

Technical Field

[0001] This utility model relates to the field of liquid forging technology, and in particular to a heat dissipation mechanism for a worktable used in liquid forging of aluminum alloys. Background Technology

[0002] As the core load-bearing component of aluminum alloy liquid forging equipment, the worktable must simultaneously withstand the weight of the die, the forging pressure, and the heat conducted by the high-temperature molten aluminum alloy. During continuous production, the heat from the molten aluminum is continuously transferred to the worktable through the die, causing the worktable temperature to gradually rise. To prevent overheating, current technologies typically employ water cooling to cover the high-heat zone in the center of the worktable, and air cooling to assist the edge areas for heat dissipation. However, the heat conducted by the molten aluminum is not uniform. This results in the heat in the center of the worktable being quickly removed by water cooling, while the edge areas, due to the slower response and lower heat exchange efficiency of air cooling, form a temperature difference zone. This temperature difference, when transferred to the die, can easily lead to differences in the solidification rate of the molten aluminum alloy, causing defects such as shrinkage cavities and cold shuts, affecting the precision of the forgings. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a heat dissipation mechanism for a worktable for liquid forging of aluminum alloy, which solves the problem that the temperature difference during heat dissipation in the prior art can easily lead to differences in the solidification rate of the aluminum alloy melt, resulting in shrinkage cavities and cold shuts in the forging.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heat dissipation mechanism for a worktable for liquid forging of aluminum alloy, including a support frame and a coolant tank installed on both sides of the top of the worktable surface. A heat dissipation component for timely removal of heat from the casting mold is provided between the support frame and the coolant tank. The heat dissipation component includes a liquid cooling pipe disposed between the support frame and the coolant tank. The inlet and outlet ends of the liquid cooling pipe are respectively inserted into the coolant tank. The side of the coolant tank near the liquid cooling pipe is set as a concave surface. Several equidistant horizontal fins are provided on the concave surface and fixed to the coolant tank. A heat dissipation fan blade for blowing away heat from the casting mold is provided on one side of the concave surface. A drive component for accelerating the flow of coolant in the liquid cooling pipe and driving the heat dissipation fan blade to rotate is provided inside the coolant tank.

[0005] Furthermore, the bottom of the liquid cooling pipe is provided with a heat dissipation plate that can be detachably installed on the workbench surface. Several vertical fins are fixed on the heat dissipation plate, and the vertical fins are perpendicular to the horizontal fins.

[0006] Furthermore, the drive assembly includes a turbine body rotatably mounted inside the coolant tank, a plurality of impeller plates arranged in a circular array fixedly mounted on the outer ring of the turbine body, and a rotating horizontal shaft fixedly mounted at the central shaft of the turbine body.

[0007] Furthermore, one end of the rotating horizontal shaft passes through the coolant tank and is rotatably connected thereto in a sealed manner, and the other end of the rotating horizontal shaft is fixedly connected to the cooling fan blades.

[0008] Furthermore, the bottom of the liquid inlet is connected to a liquid inlet pipe located inside the coolant tank, and the bottom of the liquid inlet pipe is fixedly provided with a downwardly inclined liquid inlet.

[0009] Furthermore, the bottom of the outlet end is connected to an outlet pipe located inside the coolant tank, and the bottom of the outlet pipe is fixedly provided with an outlet symmetrically arranged with the inlet.

This utility model achieves efficient and uniform heat dissipation through the synergistic arrangement of multiple heat dissipation components, effectively preventing localized areas from being covered by high-temperature backflow water for extended periods, significantly reducing the temperature difference on the worktable, ensuring uniform temperature of the casting mold, and fundamentally reducing defects such as shrinkage cavities and cold shuts caused by differences in the solidification rate of aluminum alloy melt. Furthermore, the rotating heat dissipation fan blades create an orderly airflow circulation with horizontal fins for suction and vertical fins for blowing, achieving uniform heat removal across the entire worktable and further improving heat dissipation efficiency. The overall structure, through the deep synergy of liquid cooling and air cooling, not only ensures the stable working temperature of the casting mold but also extends the service life of the heat dissipation components and the worktable, improving the forming quality and production stability of aluminum alloy forgings.

[0012] 2. This utility model achieves deep synergy between liquid cooling and air cooling through the design of a drive component, which significantly improves heat dissipation efficiency and system economy. The water turbine body drives the cooling fan blades to rotate synchronously through the rotating horizontal shaft, eliminating the need for an additional drive motor. This reduces energy consumption and also helps to blow out an orderly airflow, ensuring that the heat of the workbench is dissipated evenly. The overall structure improves the forming quality of aluminum alloy forgings, simplifies the structure of the heat dissipation system, reduces maintenance costs, and extends the service life of the workbench through power reuse, circulation optimization, and sealing protection.

[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] Aluminum alloy liquid forging technology is an advanced forming process that combines the advantages of casting and forging. It involves directly injecting molten aluminum alloy into a mold cavity and then applying pressure to solidify and shape the metal. During liquid forging on a worktable, heat is transferred to the surrounding area, requiring a heat dissipation mechanism to prevent overheating. Currently, water cooling is typically used to cover the high-heat area in the center of the worktable, with air cooling assisting the edge areas. However, temperature differences can lead to variations in the solidification rate of the molten aluminum alloy, causing defects such as shrinkage cavities and cold shuts. To precisely control the uniformity of the temperature field on the worktable, improve the quality stability and mechanical properties of the forgings, and reduce the defect rate, [further measures are needed]. Figures 1-4 As shown, the present invention provides a heat dissipation mechanism for a worktable for liquid forging of aluminum alloy, which consists of a worktable surface 1, a support frame 2, a coolant tank 3, and a heat dissipation component 4. The support frame 2 and the coolant tank 3 are respectively fixedly installed on the top two sides of the worktable surface 1. The heat dissipation component 4 is arranged between the support frame 2 and the coolant tank 3 to remove the heat of the casting mold in a timely and uniform manner, thereby eliminating shrinkage cavities and cold shut defects in the forging from the root.

[0017] The heat dissipation assembly 4 includes a liquid cooling pipe 41 disposed between the support frame 2 and the coolant tank 3. The liquid cooling pipe 41 is composed of multiple U-shaped pipes continuously combined. The casting mold can be installed between the liquid cooling pipes 41. Through the reciprocating flow channel design, the low-temperature cooling water can flow alternately through different areas of the workbench, avoiding local areas being covered by high-temperature return water for a long time. The inlet end 42 and outlet end 43 of the liquid cooling pipe 41 are respectively inserted into the coolant tank 3. The side of the coolant tank 3 near the liquid cooling pipe 41 is set as a concave surface, and several equidistantly distributed transverse fins are provided on the concave surface, which are fixed to the coolant tank 3. 44. The concave surface can increase the contact area of ​​the horizontal fins 44 and enhance the heat conduction efficiency. A heat dissipation fan blade 45 for blowing away the heat of the casting mold is provided on one side of the concave surface. A heat dissipation plate 46 that can be detachably installed on the worktable 1 is provided at the bottom of the liquid cooling pipe 41. Several vertical fins 47 are fixed on the heat dissipation plate 46 and are distributed at equal intervals. The vertical fins 47 are perpendicular to the horizontal fins 44. When the heat dissipation fan blade 45 rotates, it drives the airflow of the entire heat dissipation assembly 4. The horizontal fins 44 draw in the air and the vertical fins 47 blow the air, so as to remove the heat on the worktable more evenly.

[0018] Connecting seats are detachably installed at both ends of the top of the support frame 2, and the liquid cooling pipe 41 passes through the two connecting seats at both ends and is detachably connected to them, which can support the entire liquid cooling pipe 41 to ensure the stability of the liquid cooling pipe 41 during use, thereby achieving efficient heat dissipation.

[0019] To ensure more thorough and even heat dissipation from the workbench and improve the stability of forging quality, such as Figures 3-4 As shown, the specific implementation involves a drive assembly 48 located inside the coolant tank 3. This drive assembly 48 accelerates the flow of coolant within the liquid cooling pipe 41 and simultaneously rotates the cooling fan blades 45. The drive assembly 48 includes a turbine body 481 rotatably mounted inside the coolant tank 3. Several impeller plates 482 arranged in a circular array are fixedly mounted on the outer ring of the turbine body 481. A rotating horizontal shaft 483 is fixedly mounted at the central axis of the turbine body 481. One end of the rotating horizontal shaft 483 passes through the coolant tank 3 and is rotatably connected to it in a sealed manner. The other end of the rotating horizontal shaft 483 is fixedly connected to the cooling fan blades 45. The bottom of the liquid inlet end 42 is connected to a positioning... The coolant tank 3 has an inlet pipe 484 with a downwardly inclined inlet port 485 fixedly installed at the bottom. The bottom of the outlet end 43 is connected to an outlet pipe 486 located in the coolant tank 3. The bottom of the outlet pipe 486 is fixedly provided with an outlet port 487 symmetrically arranged with the inlet port 485. When the turbine body 481 drives the impeller plate 482 to rotate, it promotes the coolant in the coolant tank 3 to flow into the inlet pipe 484 through the inlet port 485, enter the liquid cooling pipe 41 from the inlet end 42, enter the outlet pipe 486 from the outlet end 43, and finally flow back into the coolant tank 3 from the outlet port 487, thus completing the heat exchange.
