[0028] 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.

[0029] Example 1

[0030] Please see Figure 1-4 The present invention provides the following technical solution:

[0031] A casting mold with a high-efficiency cooling system includes:

[0032] Base plate 1;

[0033] Upper plate 2 is connected to the upper end of base plate 1;

[0034] The lower casting mold 101 is connected to the upper end of the base plate 1 by bolt thread, and the upper end of the lower casting mold 101 is provided with a mold opening 102.

[0035] Guide post 105 is fixedly connected to the upper end of the lower casting mold 101;

[0036] Liquid nitrogen storage tank 201 is fixedly connected to the upper end of upper plate 2. Gas transmission steel pipe 202 is fixedly connected to the lower end of liquid nitrogen storage tank 201. Dispersing copper sheet 203 is fixedly connected to the lower end of gas transmission steel pipe 202. Side block 204 is fixedly connected to the side end of dispersing copper sheet 203. Lower plate 205 is fixedly connected to the lower end of side block 204.

[0037] The frame 206 is connected to the lower end of the lower plate 205 by bolts and threads, and the upper casting mold 207 is connected to the frame 206.

[0038] Guide port 211 is provided on frame 206, which is matched with guide post 105.

[0039] In a specific embodiment of this utility model, the base plate 1 is the basic structure of the entire mold, providing a stable support platform. It is bolted to the lower casting mold 101, ensuring the stability of the mold during use. The upper plate 2 is located above and connected to the base plate 1. Its main function is to support the liquid nitrogen storage tank 201 and other related components, provide an installation position for the upper casting mold 207, and ensure precise alignment between the upper and lower molds. Its upper end is provided with a mold opening 102 for forming the lower half of the casting. Furthermore, the lower casting mold 101 is also fixedly connected to a guide post 105 to ensure the degree of closure between the upper and lower molds. The guide post 105 is fixedly connected to the upper end of the lower casting mold 101 and matches the guide opening 211 on the frame 206, ensuring that the upper casting mold 207 can accurately descend along a predetermined path and close with the lower casting mold 101. The liquid nitrogen storage tank 201 is fixedly connected to the upper end of the upper plate 2 as a storage container for the cooling medium. It delivers liquid nitrogen to the dispersing copper sheet 203 via a gas supply pipe 202, thereby achieving a highly efficient cooling effect. The gas supply pipe 202, dispersing copper sheet 203, side block 204, and lower plate 205 constitute a cooling channel from the liquid nitrogen storage tank 201 to the interior of the casting mold. Specifically: the gas supply pipe 202 is responsible for transferring liquid nitrogen from the storage tank 201 to the dispersing copper sheet 203. The dispersing copper sheet 203 is used to evenly distribute the liquid nitrogen, increasing the cooling contact area and improving cooling efficiency. The side block 204 fixes the dispersing copper sheet 203 and connects it to the lower plate 205. The lower plate 205 supports the above components and is connected to the frame 206 by bolts. The frame 206 not only provides an installation platform for the upper casting mold 207 but also includes a guide port 211 to ensure the connection between the upper and lower molds. The upper casting mold 207 is mounted on the frame 206, forming a complete casting cavity together with the lower casting mold 101. It engages with the guide post 105 via the guide port 211 to ensure positional accuracy during closure. When casting is required, molten metal is poured into the mold cavity formed by the upper casting mold 207 and the lower casting mold 101. At this time, liquid nitrogen flows from the liquid nitrogen storage tank 201 through the gas supply steel pipe 202 into the dispersing copper sheet 203, and then is evenly distributed around the casting, rapidly carrying away heat and accelerating the cooling of the casting. This efficient cooling system not only shortens the production cycle but also significantly improves the quality of the casting, reducing problems such as deformation or cracks caused by thermal stress.

[0040] Please refer to the details. Figure 1-4 An opening 208 is provided on the side end of the upper casting mold 207, and a second inlet 210 is provided at the lower end of the opening 208. The second inlet 210 is fixedly connected to the side end of the frame 206, and the second inlet 210 matches the opening 208.

[0041] In this embodiment, the main function of the second inlet 210 is to provide an additional inlet for the cooling system to introduce a cooling medium such as liquid nitrogen. Through this inlet, the cooling medium can be delivered more directly to critical areas of the casting, ensuring rapid cooling in these areas. Since the cooling medium can directly enter the critical locations inside or near the upper casting mold 207 through the second inlet 210, the local cooling rate can be significantly improved, reducing the solidification time of the casting, thereby improving production efficiency and casting quality. The flow rate and distribution of the cooling medium can be flexibly adjusted according to the needs of different castings through the second inlet 210 to adapt to different casting process requirements and ensure optimal cooling effect. The design of the second inlet 210 also considers the maintainability of the equipment. If it is necessary to inspect, clean, or replace parts of the cooling system, tools or cleaning media can be easily connected through the second inlet 210. When liquid nitrogen or other cooling media reaches the dispersed copper sheet 203 from the liquid nitrogen storage tank 201 through the gas transmission steel pipe 202, part of the cooling medium will continue to flow downwards, while another part can directly enter the area near the upper casting mold 207 through the second inlet 210. This dual cooling path design ensures that all parts of the casting are adequately cooled.

[0042] Please refer to the details. Figure 1-4 The upper end of the lower casting mold 101 is provided with an exhaust port 103, which is matched with the exhaust valve 107.

[0043] In this embodiment, the main function of the vent 103 is to provide a gas discharge channel for the mold cavity, allowing air or other gases inside the cavity to be smoothly discharged during the pouring of molten metal, thus preventing the formation of pores inside the casting or bubbles on the surface due to residual gas. The vent valve 107 is matched with the vent 103, allowing the operator to adjust the venting speed and volume as needed. This helps optimize the casting process, ensuring that the venting process is neither too fast, causing molten metal to splash out, nor too slow, affecting the quality of the casting.

[0044] Please refer to the details. Figure 1-4 The lower end of the base plate 1 is connected to an exhaust valve 107 by bolt thread, and the exhaust valve 107 is matched with the exhaust port 103.

[0045] In this embodiment, the main function of the vent valve 107 is to control the discharge of gas within the mold cavity. Connected to the vent port 103, it allows air or other gases within the mold cavity to be smoothly discharged during the pouring of molten metal, preventing the formation of pores inside the casting or bubbles on the surface due to residual gas. The vent valve 107 allows the operator to adjust the speed and amount of venting as needed. This helps optimize the casting process, ensuring that the venting process is neither too fast, causing molten metal to splash out, nor too slow, affecting casting quality. When molten metal is poured into the mold cavity formed by the upper casting mold 207 and the lower casting mold 101, the existing air and other gases within the mold cavity are forced to be discharged through the vent port 103. The vent port 103 is located at the upper end of the lower casting mold 101, ensuring that gas can be smoothly discharged from the mold cavity without obstructing the flow of molten metal. The vent valve 107 is installed at the lower end of the base plate 1 and connected to the vent port 103 via a pipe or channel. By adjusting the opening of the vent valve 107, operators can control the venting process according to specific casting conditions such as the type and temperature of the molten metal and the pouring speed. For example, when the molten metal first enters the mold cavity, the vent valve 107 can be opened appropriately to accelerate gas discharge; while as casting nears its end, the vent valve 107 can be gradually closed to prevent excessive external air from re-entering the mold cavity. If the casting equipment is equipped with an automated control system, the operation of the vent valve 107 can also be automated. The system can automatically adjust the opening and closing time and degree of the vent valve 107 according to a preset program to ensure optimal venting throughout the casting process.

[0046] Please refer to the details. Figure 1-4 The lower casting mold 101 is fixedly connected to a first inlet 104 on its side end, and the first inlet 104 matches the mold opening 102.

[0047] In this embodiment, the primary function of the first inlet 104 is to serve as the entrance for molten metal into the mold cavity. Located on the side of the lower casting mold 101, it facilitates the introduction of molten metal by operators or automated equipment. The first inlet 104 matches the mold opening 102, ensuring that the molten metal flows accurately into the mold cavity formed by the upper casting mold 207 and the lower casting mold 101. This precise alignment helps prevent overflow or uneven filling during the pouring process. When casting begins, molten metal is introduced into the first inlet 104 from an external furnace or other source. Because the first inlet 104 matches the mold opening 102, the molten metal can flow directly and smoothly into the mold cavity without obstruction. A well-designed position and shape of the first inlet 104 guides the molten metal to fill the entire mold cavity along the optimal path, reducing problems such as cold shuts and shrinkage cavities caused by poor flow. This helps ensure that all parts of the casting are fully filled, forming a complete and dense structure. The first inlet 104 typically works in conjunction with other components in the gating system, such as the gating hopper and delivery pipelines, to achieve an efficient and stable gating process.

[0048] Please refer to the details. Figure 1-4 Both the bottom plate 1 and the top plate 2 have mounting holes 106 on their sides.

[0049] In this embodiment, the design of the mounting port 106 makes it easier for operators to install various components such as liquid nitrogen storage tank 201, exhaust valve 107, and other auxiliary equipment onto the bottom plate 1 and the top plate 2, while also facilitating the disassembly and replacement of these components.

[0050] The working principle and usage process of this utility model are as follows: First, prepare molten metal or other casting materials, ensuring they reach a suitable pouring temperature. Pour the molten material into the mold cavity formed by the upper casting mold 207 and the lower casting mold 101 through the first inlet 104. Monitor the pouring process to ensure the material fills the mold cavity evenly, avoiding problems such as bubbles and slag inclusions. Open the valve of the liquid nitrogen storage tank 201, allowing liquid nitrogen to reach the dispersed copper sheet 203 through the gas supply steel pipe 202, and then distribute it evenly around the casting for rapid cooling. If necessary, additional cooling medium can be introduced through the second inlet 210. To optimize the cooling effect, during the pouring process, keep the exhaust valve 107 open to ensure that the gas in the mold cavity can be discharged smoothly and prevent the formation of air holes. After pouring, gradually close the exhaust valve 107 to prevent too much external air from entering the mold cavity. After pouring, allow the casting to cool naturally in the mold to an appropriate temperature, or take accelerated cooling measures according to process requirements. Keep the mold closed during the cooling process to prevent external factors from affecting the quality of the casting. When the casting has completely cooled, loosen the bolts or other fixing devices, separate the upper plate 2 and the upper casting mold 207, and separate them from the lower casting mold 101.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
