[0022] To make the technical content, the purposes and the effects of the present application clear, the following will be described in detail in combination with the embodiments and the drawings.

[0023] Please refer to Figs. 1 to 3 An aluminum alloy casting system includes a casting member 1 and a crystallization member 2, the casting member 1 is used for guiding the liquefied metal to flow into the crystallization member 2, the casting member 1 includes at least one cavity 11, a vibration assembly is arranged in the cavity 11, the vibration assembly is used for generating mechanical vibration and transmitting the mechanical vibration to the liquefied metal in the casting member, so as to improve the liquidity of the liquefied metal in the casting member 1.

[0024] The utility model discloses the beneficial effect lies in: through setting up at least one cavity 11 in the cast 1 and installing vibration subassembly, make the cast 1 can produce proper vibration in the casting process, thereby increase the liquidity of liquefied metal in the cast 1. Through vibration, the viscosity and cohesion of liquefied metal are reduced, effectively avoid the flow of metal liquid in the casting process due to high viscosity and lead to the flow of not being smooth, reduce the accumulation and precipitation phenomenon of metal liquid in the cast 1, improve the quality and yield of casting. This design is especially suitable for the casting process of high viscosity metal liquid, improve the practicability of system.

[0025] In some embodiments, the cast 1 further comprises a pouring nozzle 12, which is connected with the cavity 11, and the pouring nozzle 12 is used to flow the liquefied metal in the guide cavity 11 into the crystallization piece.

[0026] From the above description, the structure of the pouring nozzle 12 is increased, which facilitates the introduction of liquefied metal in the cavity 11 into the crystallization piece, ensures that the metal liquid can flow smoothly into the crystallization piece 2, and avoids the accumulation of liquid in the cavity 11. This setting not only ensures the continuity and stability of the flow of liquefied metal, but also avoids the risk of cooling or solidification of metal liquid during the casting process, so that the metal liquid can more efficiently fill the mold, improving the production efficiency and product quality of the casting system.

[0027] In some embodiments, the vibration subassembly is arranged in the inner wall of the cavity 11 according to a predetermined interval.

[0028] From the above description, the vibration subassembly is arranged in the inner wall of the cavity 11 according to a predetermined interval, so that the liquefied metal in the cavity 11 can be uniformly affected by the vibration effect. Through reasonable interval distribution, the vibration effect can uniformly cover the entire cavity 11, so that the metal liquid flows more smoothly, reduces the flow resistance caused by high viscosity of the liquid, avoids the solidification or deposition phenomenon caused by insufficient vibration in the local area, ensures the uniform distribution of liquid metal inside the cast 1, and improves the density and quality of the cast.

[0029] In some embodiments, the vibration subassembly comprises an ultrasonic rod 13, which is used to generate vibration effect according to a predetermined frequency.

[0030] As described above, by using the ultrasonic rod 13 as a vibration component, vibration is generated within the cavity 11 at a preset frequency, enabling liquefied metal to flow more efficiently under the action of ultrasound. Ultrasonic vibration reduces the cohesive force of the molten metal, significantly improving its fluidity. Simultaneously, it prevents the generation of bubbles or impurities during flow, improving the density and surface quality of the casting. This design effectively enhances the flow performance of high-viscosity molten metal, making it particularly suitable for the molding process of complex-shaped castings. Specifically, by adjusting the power of the ultrasonic rod 13, the protective film on the surface of the molten metal is ensured not to be damaged during vibration.

[0031] In some embodiments, the nozzle 12 is at an angle to the horizontal plane.

[0032] As described above, the design of the nozzle 12 incorporates a certain tilt angle, which utilizes gravity and fluid flow characteristics to allow the molten metal to flow into the crystallizer more naturally, reducing flow resistance and backflow. This tilted structure avoids the impact of liquid backflow on fluidity, improves the guiding properties of the liquefied metal, and ensures the efficiency and stability of the liquid entering the crystallizer 2. Simultaneously, the tilt angle prevents the accumulation of molten metal inside the nozzle 12, improving the reliability and flow effect of the entire casting system. Specifically, the included angle ranges from 10° to 30°.

[0033] In some embodiments, the nozzle 12 is a tubular body, with its two ends connected to the cavity 11 and the crystallizing element 2, respectively.

[0034] As described above, the nozzle 12 is designed as a tubular structure, which effectively connects the cavity 11 and the crystallizer 2, forming a smooth flow channel for the molten metal. The tubular structure provides a more stable flow path, reducing energy loss of the molten metal during flow and preventing gas entrapment and turbulence. This design ensures that the molten metal can smoothly enter the crystallizer 2, improving fluidity and casting accuracy, reducing porosity and inclusions, and enhancing the quality of the casting.

[0035] In some embodiments, the crystallizing element 2 is a crystallizing wheel, and the circumferential side of the crystallizing wheel is provided with a wheel groove 21. The wheel groove 21 is used to contain liquefied metal and crystallize the liquefied metal. The nozzle 12 is connected to the wheel groove 21.

[0036] As can be seen from the above description, the crystallization member 2 is designed as a crystallization wheel, and the circumferential side is provided with wheel grooves 21 for receiving and crystallizing the liquefied metal. The wheel grooves 21 are designed to effectively control the flow path and crystallization process of the metal liquid, ensuring that the liquefied metal is gradually cooled and crystallized during the flow process. The communication between the pouring nozzle 12 and the wheel grooves 21 ensures that the liquefied metal can quickly and stably enter the crystallization wheel during pouring, improving the efficiency and crystallization effect of the casting process, especially suitable for continuous crystallization casting process.

[0037] In some embodiments, the pouring nozzle 12 is tangentially arranged with the wheel grooves 21.

[0038] As can be seen from the above description, by arranging the pouring nozzle 12 tangentially with the wheel grooves 21, the impact force and flow turbulence of the liquefied metal entering the wheel grooves 21 can be reduced. The tangential design can ensure that the liquefied metal enters the wheel grooves 21 of the crystallization wheel in a smoother manner, effectively avoiding bubble generation and liquid backflow phenomena in the metal liquid flow. This design further improves the stability and continuity of the metal liquid flow, which helps to improve the surface quality and density of the casting, and is suitable for the production of high-precision castings.

[0039] In some embodiments, the pouring nozzle 12 is movably connected with the cavity 11.

[0040] As can be seen from the above description, the movable connection design of the pouring nozzle 12 and the cavity 11 allows the pouring nozzle 12 to adjust the flow angle and be conveniently replaced according to the requirements, increasing the flexibility and adaptability of the entire system. This structure design facilitates the adjustment of parameters during the casting process, adapts to the casting requirements of different metal liquids, and effectively prolongs the service life of the system. The movable connection also facilitates maintenance and cleaning, reduces the risk of blockage, and ensures the stability and reliability of the system under high temperature and high viscosity conditions.

The pouring nozzle 12 is designed with a certain inclination angle, which can utilize the characteristics of gravity and fluid flow to make the metal liquid flow into the crystallization piece in a more natural way, reduce the flow resistance and backflow phenomenon. This inclined structure avoids the influence of liquid backflow on liquidity, improves the guiding property of the liquefied metal, and ensures the efficiency and stability of the liquid entering the crystallization piece 2. At the same time, the inclination angle can prevent the accumulation of metal liquid inside the pouring nozzle 12, improve the reliability and flow effect of the whole casting system.
