[0002] Lithium metal is a commonly used raw material for manufacturing products such as batteries, and is widely used in electronics, chemicals, pharmaceuticals, glass, ceramics, rubber, aerospace machinery processing and other fields. Lithium metal is usually cast into lithium ingots for storage and transportation, and lithium liquid casting molds are an indispensable piece of equipment in the lithium ingot casting process. Traditional casting molds are prone to causing porosity defects in lithium ingots to a certain extent, reducing the yield of lithium ingots and affecting the performance of lithium ingots. In addition, after the lithium ingots are cast, the mold is usually demolded manually, which is labor-intensive for operators. During demolding, the lithium ingots are easily scratched, causing damage to their appearance and reducing product quality. Utility Model Content

[0003] To address the aforementioned problems, the main objective of this invention is to provide a lithium ingot casting and demolding device for use in glove boxes. This device improves the quality of lithium ingot products, achieves automated demolding, and reduces the likelihood of lithium ingots being damaged in appearance during the demolding process.

[0004] To achieve the above objectives, this utility model provides a lithium ingot casting and demolding device for use in a glove box, comprising a mold support, a mold component, a mold demolding component, a mold base plate, a mold moving component, and a mold lifting device. The mold demolding component is movably located at the bottom of the mold component. The mold component and the mold demolding component are located on the upper surface of the mold base plate. The mold moving component passes through the mold base plate and is connected to the bottom of the mold demolding component. The upper end of the mold lifting device is connected to the bottom of the mold moving component. The mold lifting device is used to realize the vertical movement of the mold moving component.

[0005] In other embodiments, the mold component has a cylindrical structure, and the inner diameter of the mold component gradually increases from bottom to top.

[0006] In other embodiments, the diameter of the mold release element is the same as the diameter of the inscribed circle on the bottom surface of the mold element.

[0007] In other embodiments, the bottom of the mold base plate is provided with mold support legs, and the upper ends of the mold support legs are fixed to the lower end face of the mold base plate.

[0008] In other embodiments, the lower end of the mold support leg is provided with ball bearings, which roll on the bottom plate of the glove box.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] A glove box, also known as a vacuum glove box, is a laboratory device that fills a chamber with high-purity inert gas and circulates it to filter out active materials. It can be used in the production and research and development of lithium-ion battery electrode materials, preventing performance degradation caused by contact between the product and moisture and oxygen during production. The lithium ingot casting and demolding device of this invention is applied within a glove box. Figure 1The diagram shows a cross-sectional view of the lithium ingot casting and demolding device for a glove box according to this invention. The device includes a mold support 1, which is fixedly mounted on the glove box base plate 10. The upper end of the inner wall of the mold support 1 has a groove (not shown in the diagram), and a mold limiting member 2 is slidably disposed within the groove. The device also includes a mold component 3, which is cylindrical in shape. The inner diameter of the mold component 3 gradually increases from bottom to top, forming a cylindrical structure with the upper end larger than the lower end. This shape facilitates the smooth casting of lithium liquid and ensures the stability of the molding process. Furthermore, the mold limiting member 2 is connected to the outer wall of the mold component 3, and the mold component 3 is stably fixed to the mold support 1 through the cooperation of the mold limiting member 2 and the groove.

[0018] Please continue reading. Figure 1 As shown, the mold release component 5 of this utility model is movably located at the bottom of the mold component 3. The diameter of the mold release component 5 is the same as the diameter of the inscribed circle on the bottom surface of the mold component 3. At the same time, both the mold component 3 and the mold release component 5 are located on the upper surface of the mold base plate 6. The mold base plate 6 can lock the mold component 3 in a fixed position to prevent it from being misaligned or displaced. The mold moving component 7 extends from the bottom of the mold base plate 6 and is fixedly connected to the bottom of the mold release component 5. The upper end of the mold lifting device 8 is connected to the bottom of the mold moving component 7. Thus, the mold lifting device 8 can drive the mold moving component 7 to move in the vertical direction. It should be noted that in this embodiment, the mold lifting device 8 uses hydraulic oil to drive the hydraulic oil pipe as a power source. In other embodiments, the mold lifting device 8 can also use electric or pneumatic methods as a power source. There is no limitation here. Any structure that can realize the vertical displacement of the mold moving component 7 is included.

[0019] In other implementations, such as Figure 1 As shown, the bottom of the mold base plate 6 is provided with mold support legs 4. The upper end of the mold support legs 4 is fixed to the lower end face of the mold base plate 6. The lower end of the mold support legs 4 is provided with ball bearings 9. The ball bearings 9 are rotatably connected to the lower end of the mold support legs 4. The ball bearings 9 can roll on the glove box base plate 10. When the mold part 3 after the lithium liquid casting is completed needs to be demolded, the mold part 3 is moved into the mold support 1 under the rotation of the ball bearings 9 until the mold limiting part 2 is just engaged in the sliding groove on the mold support 1. Thus, the mold part 3, the mold limiting part 2 and the mold support 1 are fixed in the direction perpendicular to the horizontal plane. Then, the mold lifting device 8 is activated to move the mold moving part 7 upward. At the same time, the mold demolding part 5 is pushed to push the lithium ingot in the mold part 3 upward, and finally the casting and demolding process is realized.

[0020] In the use of this utility model's lithium ingot casting and demolding device, the first step is to determine the scheme based on actual needs. Combining the actual dimensions of the lithium ingot, the sizes of mold component 3 and mold demolding component 5 are designed so that the mold demolding component 5 and mold component 3 are integrated to reduce lithium leakage during the casting process. After the above preparations are completed, mold component 3 and mold demolding component 5 are placed together on the mold base plate 6. A mold moving component 7 is installed below the mold demolding component 5, penetrating the mold base plate 6. After the lithium liquid is cast, the mold component 3, mold demolding component 5, and mold support leg 4 are moved by ball bearings 9, causing the mold limiting component 2 to fit into the groove of the mold support 1. Under the positioning action of the mold support 1 and mold limiting component 2, and through the cooperation of the mold demolding component 5, mold moving component 7, and mold lifting device 8, the lithium ingot inside the mold component 3 can be detached from the mold component 3. It should be noted that the weight of the mold component 3 in this invention is significantly greater than the frictional force between it and the lithium ingot. This ensures that when the mold moving component 7 pushes the mold demolding component 5 and the lithium ingot above it upwards, the mold component 3 remains stably positioned on the mold base plate 6, allowing the lithium ingot to completely detach from the mold component 3 and thus achieve demolding. This device is simple to operate and maintain, preventing damage to the appearance of the lithium ingot caused by operator intervention during the demolding process. It also reduces the workload of workers and improves production efficiency.

[0021] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
