Description

TECHNICAL FIELD

[0001] The application relates to the technical field of aluminum alloy casting equipment, in particular to a deep-well casting device for aluminum alloy casting rods. BACKGROUND

[0002] Aluminum alloy is widely used in many fields such as aerospace, automobile and mechanical manufacturing due to its low density, high strength, good plasticity and the like. As an important blank for aluminum alloy processing, the quality of an aluminum alloy casting rod directly affects the performance and quality of a subsequent processing product. At present, deep-well casting is one of common methods for producing aluminum alloy casting rods, which can produce casting rods with large size and high quality.

[0003] Patent Publication No. CN220679335U proposes a deep-well casting mold for aluminum alloy rods, which comprises a deep well, a cooling water at the bottom of the deep well, a nozzle on the inner wall of the upper part of the deep well, a shunt disc at the uppermost part of the deep well, an aluminum rod mold inside the shunt disc, an aluminum liquid inlet at one end of the shunt disc, a filter screen inside the aluminum liquid inlet, and a hydraulic mechanism above the shunt disc. The shunt disc moves to the bottom of the deep well under the drive of the hydraulic mechanism, at which time the multiple layers of nozzles uniformly spray the aluminum rod mold, which makes the aluminum liquid cool more uniformly. When the aluminum rod mold continues to move downward and contacts the cooling water, the cooling water further uniformly cools the aluminum liquid.

[0004] In view of the related technologies in the above, the inventors have found the following defects: The above device mainly relies on the cooling water at the bottom of the deep well and the nozzle on the inner wall of the upper part for cooling. This cooling method is relatively simple, and the cooling liquid circulation system is not perfect, lacking efficient circulating pumps and reasonable shunt pipeline design. In actual production, the cooling liquid may not flow quickly and uniformly through the entire casting mold area, resulting in limited cooling speed and failing to meet the needs of large-scale and high-efficiency production. Moreover, the single cooling method makes heat dissipation not fast enough, which easily causes local temperature to be too high, affecting the internal organizational structure and performance uniformity of the aluminum alloy casting rod.

[0026] Both the first cooling mechanism 51 and the second cooling mechanism 52 include a first diversion plate 509, a first diversion frame 510, a first diversion groove 511, a hollow heat dissipation plate 512, a transfer pipe 513, a second diversion frame 514, a second diversion groove 515, and a second diversion plate 516.

[0031] Further explanation is needed:

[0032] The cooling component 5 plays a crucial role in the deep-well casting device for aluminum alloy cast rods. Its functions are mainly reflected in two aspects: efficient cooling and uniform heat dissipation. In terms of efficient cooling, it constructs a complete coolant circulation system. The injection pipe 501 is responsible for injecting coolant into the outer shell 1 of the cooling chamber. The circulation pump 502 provides power for the flow of coolant, which passes through the first circulation pipe 503 and the branch pipe 504 into the first cooling mechanism 51. After the first cooling mechanism 51 performs preliminary cooling on the coolant, it is transported to the second cooling mechanism 52 for further cooling through the double-pass pipe 505. Finally, the cooled coolant returns to the outer shell 1 of the cooling chamber through the second circulation pipe 508, realizing the recycling of coolant. This continuous circulating cooling method can quickly and effectively remove the large amount of heat generated by the aluminum alloy cast rod during the casting process, ensuring that the cast rod can be cooled and formed quickly, improving production efficiency and cast rod quality.

[0033] Meanwhile, the cooling assembly 5 also has the function of uniform heat dissipation. The internal flow distribution structure of the first cooling mechanism 51 and the second cooling mechanism 52 is cleverly designed. The first flow distribution plate 509, the first flow distribution frame 510 and the first flow distribution groove 511 with trapezoidal cross section and equal spacing can make the coolant evenly dispersed. Similarly, the second flow distribution frame 514, the second flow distribution groove 515 and the second flow distribution plate 516 also play a similar role. In addition, the honeycomb heat conduction structure inside the hollow heat dissipation plate 512 greatly increases the heat dissipation area and can dissipate heat more efficiently. These designs enable the coolant to contact the casting rod evenly throughout the cooling process, avoid local overheating, ensure the cooling effect of each part of the casting rod is consistent, and thus improve the quality stability of the casting rod.

[0034] The working principle of the above embodiments is as follows:

[0035] First, liquid aluminum alloy is introduced into the crystallizer 2. The cooling chamber shell 1 provides a relatively stable spatial environment for the entire casting process. The barrier ring 3 prevents external impurities from falling into the cooling chamber and affecting the casting quality. The hydraulic telescopic rod of the hydraulic push rod mounting well 4 is in the initial position. The end face seal ensures the connection and sealing with the crystallizer 2 to avoid coolant leakage. At the same time, the circulating pump 502, heat exchanger 506 and other equipment of the cooling component 5 are started to prepare for coolant circulation and cooling.

[0036] Next, the coolant is injected into the cooling chamber shell 1 through the injection pipe 501, and the circulation pump 502 starts to work, providing power to make the coolant enter the first circulation pipe 503. The coolant flows along the first circulation pipe 503 to the distribution pipe 504, and the distribution pipe 504 distributes the coolant evenly into the first cooling mechanism 51, and begins the initial heat dissipation treatment of the coolant.

[0037] Next, the coolant entering the first cooling mechanism 51 first enters the distribution cavity formed by the first distribution frame 510 and the first distribution plate 509 through the first distribution plate 509, and then is evenly distributed to the hollow heat dissipation plate 512 through the first distribution groove 511. The honeycomb heat conduction structure inside the hollow heat dissipation plate 512 increases the heat dissipation area and effectively dissipates the heat of the coolant. Then, the coolant flows into the second distribution frame 514 through the transfer pipe 513, and then gathers into the distribution cavity formed by the second distribution plate 516 and the second distribution frame 514 through the second distribution groove 515. After that, the coolant flows into the second cooling mechanism 52 through the double pipe 505, and repeats a similar distribution and heat dissipation process in the second cooling mechanism 52 to further reduce the coolant temperature.

[0038] Next, the pump body built into the heat exchanger 506 drives the coolant inside the coolant circulation chamber to circulate. The spiral coil inside the heat exchange tube 507 increases the heat exchange area between the coolant and the outside. During this process, the coolant flowing through the first cooling mechanism 51 and the second cooling mechanism 52 exchanges heat with the coolant in the coolant circulation chamber, further reducing the coolant temperature to ensure that the coolant always has a good cooling effect.

[0039] Finally, the coolant cooled by the second cooling mechanism 52 flows back to the outer shell 1 of the cooling chamber through the second circulation pipe 508, and cools the aluminum alloy casting rod in the crystallizer 2 again, realizing the recycling of the coolant. During the casting process, the hydraulic telescopic rod of the hydraulic push rod mounting well 4 can be extended and retracted as needed to assist in the forming and demolding of the casting rod. This cycle is repeated to complete the deep well casting process of the aluminum alloy casting rod.

[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
