[0002] In the modern metal manufacturing field, improving production efficiency and optimizing product quality have always been the goals pursued by the industry. The casting machine turnover water inlet single runner assembly is one of the key technologies to achieve this goal. The design and application of this assembly reflect the continuous innovation and improvement of the metal casting process. The casting process is an important part of metal processing, and the runner system, as a key link in the casting process, directly affects the quality of the entire casting. First, the theory of fluid mechanics provides a theoretical basis for runner design. When the fluid flows through a complex runner system, phenomena such as pressure changes and turbulence will occur. Accurately grasping these laws is crucial for the reasonable design of the runner. In addition, the development of numerical simulation technology also provides a powerful tool for runner optimization, which can simulate complex casting processes and provide a basis for determining process parameters.

[0022] Embodiment 1

[0023] As Figures 1-6 shown, a casting machine flipping water inlet single runner assembly includes an upper die 1, a casting die 2 and a lower die 3. One side of the upper surface of the lower die 3 is fixedly connected with a pouring gate 4, and one side of the upper surface of the lower die 3 is fixedly connected with a main runner 5;

[0024] In this embodiment, one side of the upper surface of the lower die 3 is fixedly connected with a sub-runner 6, and the lower die 3 is movably connected with the casting die 2.

[0025] During specific use, the user pours the aluminum alloy raw material into the pouring gate 4, and through the main runner 5, pours the aluminum alloy raw material at 700 - 740 °C into the casting die 2. At the same time, through the pouring gate 4, the aluminum alloy raw material at 700 - 740 °C flows into the sub-runner 6 and enters the inside of the casting die 2 through the two-side sub-runners 6, achieving single-way rapid pouring of the casting die 2.

[0026] In this embodiment, one side of the outer surface of the lower die 3 is fixedly connected with a U-shaped support plate 7, and one side of the outer surface of the U-shaped support plate 7 is fixedly installed with a motor 8. The output end of the motor 8 penetrates one side of the outer surface of the U-shaped support plate 7 and extends to one side of the inner wall of the U-shaped support plate 7. The output end of the motor 8 is fixedly connected with a support rod 9, and one end of the support rod 9 is fixedly connected with the fixing piece 10.

[0027] During specific use, by starting the motor 8, the U-shaped support plate 7 supports the operation of the motor 8, and the support rod 9 rotates to achieve the flipping process, improving the runner efficiency and the product qualification rate. The cooling effect is achieved by setting holes in the support rod 9.

[0028] In this embodiment, a fixed block 11 is movably connected to one side of the upper surface of the lower mold 3, and a support column 12 is fixedly connected to the upper surface of the lower mold 3 at one time. The fixed block 11 and the support column 12 are slidably connected.

[0029] During specific use, by fixedly connecting the support column 12 to the lower mold 3, after installing the casting mold 2, the fixed block 11 and the support column 12 are butted against each other to achieve the purpose of fixing the position of the casting mold 2 and prevent the position from shifting during pouring.

[0030] In this embodiment, a drainage hopper 13 is fixedly connected to one side of the outer surface of the lower mold 3.

[0031] During specific use, the drainage hopper 13 is connected to the lower mold 3 to prevent the poured aluminum alloy raw material from leaking out through the drainage hopper 13.

[0032] In this embodiment, a handle 14 is fixedly connected to one side of the upper surface of the upper mold 1.

[0033] During specific use, by connecting the handle 14 to the upper mold 1, the handle 14 lifts the upper mold 1 to achieve the purpose of facilitating the disassembly and installation of the upper mold 1.

[0034] In this embodiment, a riser 15 is movably connected to one side of the outer surface of the casting mold 2.

[0035] During specific use, the riser 15 is used to guide the flow of molten metal into the mold cavity, ensuring that the molten metal can flow smoothly to all parts in the casting mold 2, ensuring the complete filling of the casting, and promoting the rapid solidification of the casting, which helps to avoid the formation of over-sized internal grains or hot cracks.

[0036] Working principle: During use, mold flow analysis is carried out through software, and the aluminum inlet flow rate and runner are simulated through the system. The meeting discusses the collision problem points that will be encountered during production and finally confirms the solution. After that, the mold is modified, the mold is tested, adjusted and corrected, and finally the mold is confirmed. The lower mold 3 is fixedly connected with the support column 12. After installing the casting mold 2, the fixing block 11 is butted against the support column 12 to fix the position of the casting mold 2 to prevent position deviation during pouring. The drainage hopper 13 is used to prevent the leakage of the poured aluminum alloy raw material. The casting is carried out through the pouring port 4. Through the main runner 5, the aluminum alloy raw material at 700 - 740 °C is poured into the casting mold 2. At the same time, through the pouring port 4, the aluminum alloy raw material at 700 - 740 °C flows into the sub-runners 6 and enters the inside of the casting mold 2 through the two side sub-runners 6. At the same time, the gas content of the metal is reduced, and it is ensured that the molten metal is evenly cooled during the filling process to achieve single-item rapid completion of the casting of the casting mold 2. The motor 8 is started, and the U-shaped support plate 7 supports the operation of the motor 8. The support rod 9 rotates to achieve the flipping process, improving the runner efficiency and the product yield rate. The cooling effect is achieved by setting holes on the support rod 9. The riser 15 is used to guide the molten metal to flow into the mold cavity to ensure that the molten metal can flow smoothly to each part in the casting mold 2, ensuring the complete filling of the casting and promoting the rapid solidification of the casting, which helps to avoid the formation of over-large internal grains or hot cracks. After the casting is completed, the upper mold 1 is lifted by the handle 14 connected to the upper mold 1. The casting is taken out from the mold of the casting machine according to the product production situation. Then, the flash, burrs and gates of the casting are cleaned, and the temperature is heated to 535 - 545 °C with a holding time of 2 - 3 h; then quenching is carried out: the water temperature is 50 - 80 °C, and then artificial aging is carried out. The heating temperature is 195 - 205 °C with a holding time of 2 - 3 h, and then air cooling is carried out. The casting is finished by using CNC, shot blasting machine and stainless steel balls for shot blasting. The casting is machined to process the required structure. The casting is washed to remove impurities such as oil stains and powder chips attached to the surface, and the casting is completed.
