Description

Technical Field

[0001] The utility model relates to the field of aluminum alloy production, in particular to an aluminum alloy ingot casting mold. Background Art

[0002] A mold is a tool used for shaping in industrial production. During the production process, the factory melts the aluminum block into aluminum liquid in advance, and usually injects the molten metal into the mold for cooling and molding. After the aluminum liquid is molded into an aluminum ingot, the aluminum ingot is removed from the mold. During the cooling and molding process of the aluminum ingot, the mold is generally cooled by water sprayed from a cooling device, i.e., a spray nozzle. However, the cooling device is generally set directly above the mold, and the water flow is directly sprayed on the upper surface of the mold. The lower surface of the mold is difficult to contact the coolant, and the cooling effect is not good. In addition, the sprayed water cannot be recycled, resulting in waste. Therefore, a casting mold that can be circulated and cooled is needed to reduce the cooling cost of the factory. Summary of the invention

[0015] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0016] Please refer to Figure 1 , Figure 2 and Figure 3 , an aluminum alloy ingot casting mold according to an embodiment of the utility model comprises a mold and a cooling system, wherein the cooling system is arranged around the mold;

[0017] A casting hole 8 is provided on the upper surface wall of the mold, and the mold is divided into an upper mold 1 and a lower mold 2. A protruding limiting groove 3 is provided around the upper mold 1, and an indented clamping groove 4 is provided on the edge of the lower mold 2. The limiting groove 3 is adaptively sealed and clamped in the clamping groove 4. A clamping device is provided on the edge of the mold, and the clamping device clamps the upper mold 1 and the lower mold 2. A cooling layer 5 is fixedly provided on the outer surface wall of the mold, and a cooling system is provided in the cooling layer 5;

[0018] The cooling system includes a plurality of guide pipes 6 and a reflow pool 7. The guide pipes 6 are fixedly and evenly arranged in the cooling layer 5. The guide pipes 6 are fixedly connected to the reflow pool 7. The extension direction of the guide pipes 6 is consistent with the extension direction of the surface wall of the upper mold 1. The length of the guide pipes 6 is greater than the length of the entire cooling layer 5.

[0019] The mold cools the aluminum ingot in the mold through the guide pipe 6 evenly wrapped around the mold, ensuring a uniform cooling effect, and the coolant enters the cooling layer 5 from the guide pipe 6 and then flows back from the guide pipe 6 to the reflux pool 7, thereby realizing the recycling of the coolant, reducing the cost of using the coolant, and improving production efficiency.

[0020] Preferably, the casting hole 8 is an inverted truncated cone-shaped structure, and the larger bottom surface of the casting hole 8 is closer to the center of the mold than the smaller bottom surface.

[0021] The casting hole 8 with an inverted truncated cone structure can not only increase the flow rate of the molten aluminum during casting, but also make the molten aluminum have higher fluidity, thereby avoiding obstruction of the casting process of the melt.

[0022] Preferably, the casting hole 8 is arranged higher than the upper surface wall of the upper mold 1, and a residual material area 9 is arranged between the casting hole 8 and the upper surface wall of the upper mold 1. The residual material area 9 is connected to the upper mold 1, and the diameter of the residual material area 9 is consistent with the maximum bottom diameter of the casting hole 8.

[0023] During the casting process, an extra section of excess material is produced in the excess material area 9 to ensure that the surface of the aluminum ingot near the casting hole 8 meets the specifications and that no defective gaps appear on the surface of the aluminum ingot below the casting hole 8 .

[0024] Preferably, the guide pipe 6 includes an inlet pipe and an outlet pipe, the inlet pipe is a pipeline for the coolant from the reflux pool 7 to the cooling layer 5, and the outlet pipe is a pipeline for the coolant from the cooling layer 5 to the reflux pool 7. An extraction pump is provided in the reflux pool 7, and the extraction pump is sealed and connected to the inlet pipe through a hose. The water outlet of the outlet pipe is provided on the bottom surface of the reflux pool 7, and the horizontal position of the reflux pool 7 is below the horizontal position of the cooling layer 5.

[0025] The existence of the reflux tank 7 is used to circulate and recycle the cooling liquid, thereby reducing the cooling cost of the entire mold and improving the cooling efficiency.

[0026] Preferably, a heat recovery chamber 10 is provided outside the outlet pipe, and the outlet pipe is passed through the heat recovery chamber 10. A medium for recovering heat is provided in the heat recovery chamber 10. The heat recovery chamber 10 is used to recycle the waste heat brought out by the coolant, thereby achieving the effect of energy saving and efficiency improvement. The medium for recovering heat can be water or air, and the recovered heat can be used for heating or providing heat.

[0027] In order to facilitate the movement of the mold, the guide pipe 6 located at the reheat chamber 10 can be set as a hose to facilitate the opening or closing of the mold, and since the temperature at the inlet pipe is relatively low, a hose can also be used to transport the coolant.

[0028] As described above, when the utility model is actually used, the upper mold 1 and the lower mold 2 are sealed and fastened by a snap-fit ​​device, and a sealing ring is provided in the snap-fit ​​groove 4. The sealing ring is used to seal the snap-fit ​​groove 4 and the limit groove 3. After the upper mold 1 and the lower mold 2 are sealed, molten aluminum is poured into the mold from the casting hole 8 for casting. After the casting is completed, the extraction pump in the reflux pool 7 is opened, and the extraction pump extracts the coolant in the reflux pool 7. The coolant enters the cooling layer 5 through the guide pipe 6 and cools the mold. The heated coolant flows back from the outlet pipe to the reflux pool 7, and the heat brought out by the coolant during the reflux process is absorbed by the heat recovery medium in the heat recovery chamber 10, which has the effect of waste heat recovery. The entire mold not only solves the problem of uneven mold cooling, but also can recycle the coolant, thereby improving the utilization rate of the coolant and reducing the cooling cost.

[0029] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any changes and modifications made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
