Description

Technical Field

[0001] The invention relates to the technical field of metal lithium production, in particular to a mould for ensuring safe casting of metal lithium. Background Art

[0002] The casting process of metallic lithium is usually carried out under strictly controlled conditions to ensure the safety of operation and the quality of lithium ingots. This process is usually completed in a sealed glove box protected by argon gas to prevent lithium from reacting with oxygen and water vapor in the air. In order to achieve this goal, specific molds are required to contain and shape liquid metallic lithium. These molds usually consist of a tray and a mold body. The mold body is placed on the tray during the casting process and pushed under the casting port. Once the lithium liquid cools and solidifies into a lithium ingot, the mold body can be laid down or lifted to allow the lithium ingot to be demolded smoothly.

[0003] However, the traditional mold design has exposed several key problems in practical applications. On the one hand, there is a lack of a stable fixing mechanism between the mold body and the tray, which leads to the possibility that liquid lithium will seep out from the gap between the mold body and the tray during casting and mold movement, resulting in lithium waste and potential safety hazards. On the other hand, some mold designs integrate the bottom with the mold body, which enhances the overall structural strength of the mold, but significantly increases the weight of the mold, making it extremely difficult to flip the mold and remove the lithium ingot, and it is easy to damage the integrity of the lithium ingot during the flipping process.

[0004] After searching, Chinese patent CN207386505U discloses a casting mold for metal lithium ingots, including a box-shaped mold box and a mold cover plate, the mold cover plate has a detachable sealing cover arranged on the top of the mold box, the mold cover plate is fixed or integrally formed with a casting tube, the casting tube is provided with a casting hole, the casting hole connects the mold cover plate and the inside and outside of the mold box, the outer diameter of the mold cover plate is greater than or equal to the inner diameter of the box mouth of the mold box, and the utility model is a casting mold for metal lithium ingots, which is simple to operate, has high single-batch production output, high product yield and good product weight consistency.

[0005] After searching, Chinese patent CN213944806U discloses an automatic casting mold, the main purpose of which is to improve the casting efficiency of metal lithium ingots. The main technical solution of the utility model is: an automatic casting mold, which includes: a shell, a covering mechanism and a jacket; the upper end of the shell is connected to the liquid inlet pipe, the vacuum tube and the argon gas tube, and the lower end of the shell is provided with a mouth; the covering mechanism includes a support plate, a threaded rod, a bottom cover and a hook body, one end of the support plate is rotatably connected to one side of the lower end of the shell, and the other end is rotatably connected to one end of the hook body, and the other end of the hook body is hooked to the other side of the lower end of the shell, the threaded rod is threadedly connected to the middle part of the support plate, and the upper end of the threaded rod is fixedly connected to the bottom cover, which is used to drive the bottom cover to be connected to the mouth; the jacket is attached to the axial side wall of the shell.

[0006] After searching, Chinese patent CN218283660U discloses a metal lithium multi-element alloy ingot casting mold, including a mold wall and a baffle, the mold wall is a hollow cylindrical tube as a whole, and the interior is a hollow area; the upper part of the mold wall is connected to a coolant outlet, and the lower part of the mold wall is connected to a coolant inlet; the baffle is located in the hollow area and between the coolant outlet and the coolant inlet, and is used to block the coolant entering and leaving. The utility model can ensure that the cooling rate of the metal lithium multi-element alloy ingot is consistent at all places, and the cooling rate is adjusted by the flow rate of the coolant, so that the organizational structure of each place in the ingot is more compact, the internal shrinkage cavity is shallow, and the product quality and product yield are improved.

[0007] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art: In the prior art, although there have been a variety of design schemes for metal lithium casting molds, they have not completely solved the above-mentioned problems. For example, a casting mold for a metal lithium ingot disclosed in Chinese patent CN207386505U adopts a detachable sealing cover design. Although it is convenient to take out the lithium ingot, there is a risk of lithium leakage at the joint between the sealing cover and the mold box, which not only reduces the safety of the casting process, but also may have an adverse effect on the quality of the lithium ingot; for example, an automatic casting mold disclosed in Chinese patent CN213944806U, although it improves the production efficiency to a certain extent, the splashing problem of lithium liquid during the casting process is still difficult to avoid, which is mainly used to produce metal lithium intermediates with low appearance requirements, and cannot meet the application scenarios with strict requirements on the quality of lithium ingots; for example, a metal lithium multi-element alloy casting mold disclosed in Chinese patent CN218283660U accelerates the cooling process of the lithium ingot by introducing a coolant into the hollow area of ​​the mold wall, but this method easily causes the lithium ingot to be contaminated by the coolant, and at the same time, too fast a cooling speed will also increase the hardness of the lithium ingot, thereby affecting its subsequent extrusion molding effect. Therefore, the existing metal lithium casting mold design still needs to be further improved and optimized.

[0008] Therefore, the above technical problems need to be solved. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 , Figure 6 , Figure 7 , Fig. 9 , Fig.10 and Fig.11 The present invention provides a technical solution: a mold for ensuring safe casting of metallic lithium, comprising a base 100 and a mold body 300 erected on the base 100 through a flip frame 200, and two guide components 400 respectively assembled on the left and right sides of the top of the base 100 for stably conveying the base 100 on the production line and a monitoring mechanism 500 erected above the production line for detecting the height of lithium liquid, the flip frame 200 is composed of a support platform 210 installed in the middle of the top surface of the base 100 and an actuator 220 for flipping it, the support platform 210 includes two fixed columns 21 10 is hinged to a flap 2120 above the base 100 and two support columns 2130 for supporting the flap 2120 away from its hinged end. A receiving hole 2150 is provided in the middle of the flap 2120 for embedding the bottom of the mold body 300. The mold body 300 includes a cylinder 310 and a sealing plate 330 coaxially packaged at the bottom of the cylinder 310 by a plurality of screws 320. A boss 340 is coaxially provided on the top of the sealing plate 330 and fits the inner wall of the cylinder 310. A mounting plate 3110 is provided on the outer wall of the bottom of the cylinder 310 for fixedly connecting it to the flap 2120.

[0025] Based on the above-mentioned structural setting, the mold for ensuring safe casting of metallic lithium is composed of a base 100, a flip frame 200, a mold body 300, a monitoring mechanism 500 and two guide components 400, wherein the mold body 300 is connected to the flip frame 200, the base 100 serves as a support for the mold body 300 and can be placed on a production line, the sealing plate 330 is connected to the cylinder 310 to form a container for receiving metallic lithium liquid, the sealing plate 330 is fixedly connected to the bottom of the cylinder 310 by screws 320 to form a closed state, and only the top opening of the cylinder 310 is retained for the casting input of lithium liquid. Specifically, during the working process, the mold body 300 is placed on the production line in the glove box with the base 100. Subsequently, after starting the melting and casting process of the metallic lithium liquid, the molten lithium liquid is guided into the mold body 300. When the height of the molten lithium liquid in the mold gradually rises and reaches the preset low liquid level electrode 530 detection point, the casting stops. The mold body 300 absorbs the heat of the molten lithium liquid and exchanges heat with the protective gas circulating in the glove box through the heat dissipation groove 3120 on the outer wall. The molten lithium liquid solidifies due to the drop in temperature and eventually drops to the ambient temperature. At this time, the mold body 300 is taken away from the casting position by the production line along with the base 100. The next mold body 300 is moved to the casting position along with the base 100 to start casting the next mold body 300. All the mold bodies 300 are completed in sequence. 00 casting, the mold body 300 is arranged in sequence and pushed to the next process, and the lithium ingot can be taken out from the mold body 300 in conjunction with the flip frame 200. The mold that ensures the safe casting of metallic lithium is sealed with a sealing plate 330 at the bottom of the cylinder 310 by means of screws 320, and cooperates with the boss 340 set on the sealing plate 330 to ensure the sealing of the bottom of the mold body 300. At the same time, a mounting plate 3110 is set on the outer wall of the bottom of the cylinder 310 to ensure the stability of the connection between the mold body 300 and the flip plate 2120, effectively preventing the leakage and seepage of liquid lithium during casting and mold movement, thereby greatly improving the safety of the casting process. The turning frame 200, with the aid of the supporting platform 210 and the actuator 220, allows the mold body 300 to be easily turned over, which is convenient for demolding and removing the lithium ingot. At the same time, the design of the flap 2120 allows the mold body 300 to be stably placed on the base 100 during the casting process. The design of the guide assembly 400 makes the transportation of the mold body 300 on the production line more stable, reduces the shaking and collision of the mold during transportation, ensures the safety of the mold during transportation, and at the same time, ensures the quality of the lithium ingot. The design of the monitoring mechanism 500 can monitor the height of the lithium liquid in real time, ensure the accuracy and stability of the casting process, thereby improving production safety and efficiency.

[0026] For further information, see Figure 7, and also includes two first locking screws 2140 for positioning the flap 2120, the two first locking screws 2140 are respectively movably penetrated through the two support columns 2130 and are both threadedly connected to the flap 2120. The first locking screws 2140 are used to lock and limit the flap 2120 parallel to the base 100, ensuring that it provides a stable supporting effect for the mold body 300. Specifically, the inner end of the first locking screw 2140 is movably penetrated through the support column 2130 from the top of the outer side of the support column 2130 and is threadedly assembled on the side of the flap 2120, thereby locking and fixing the flap 2120.

[0027] For further information, see Figure 2 and Figure 3 The guide assembly 400 includes a slide rail 410 fixedly installed on the base 100 in a transverse direction, two slide seats 420 slidably mounted on both ends of the slide rail 410, and two rollers 430 respectively mounted on the outer ends of the tops of the two slide seats 420. The inner ends of the tops of the two slide seats 420 are vertically threaded with second locking screws 440 for positioning. The rollers 430 protrude from the base 100 and serve as guide wheels when the mold body 300 runs with the base 100 on the production line. The slide seat 420 slidably mounted on the slide rail 410 cooperates with the second locking screw 440. The operator can adjust the distance of the rollers 430 protruding from the base 100 in real time, which can adapt to the guidance on different production lines, thereby improving the applicability and flexibility.

[0028] For further information, see Figure 2 and Figure 4 , and also includes four anti-collision components 110, which are divided into two groups and are respectively arranged on the left and right sides of the base 100. The anti-collision components 110 include anti-collision columns 1110 that can be threadedly assembled on the base 100, and the outer ends of the anti-collision columns 1110 are clamped with rubber sleeves 1120. Among them, the anti-collision components 110 are installed on the side of the base 100 and protrude from the mold base 100, and are used to reduce the impact force when the multiple mold bodies 300 are running with the base 100.

[0029] For further information, see Figure 6 and Figure 8The actuator 220 includes a screw rod 2220 rotatably mounted on the base 100 through two vertical plates 2210 and distributed along the length direction of the base 100, a slider 2230 threadedly sleeved on the outside of the screw rod 2220, and two limit seats 2240 respectively fixedly connected to the two sides of the bottom of the flap 2120, a knob 2250 is fixedly installed on the left end of the screw rod 2220, a connecting rod 2260 is hinged on the top of the slider 2230, and a laterally distributed support rod 2270 is provided on the top of the connecting rod 2260, and the two ends of the support rod 2270 are respectively slidably installed in the two limit seats 2240. The actuator 220 is used to realize the flipping action of the flap 2120. The screw rod 2220 can be driven to rotate by turning the knob 2250, and the slider 2230 can move along the screw rod 2220. The flipping angle of the flap 2120 can be adjusted by supporting the two limit seats 2240 with the help of the connecting rod 2260 and the support rod 2270. Figure 6 and Fig. 9 As shown, there are two working states of the flap 2120, namely, lying flat and flipping over.

[0030] For further information, see Fig.10 and Fig.11 The inner wall of the cylinder 310 is a conical structure with a large top and a small bottom, and a plurality of heat dissipation grooves 3120 in an annular structure are provided on the outer wall of the cylinder 310. Among them, the cylinder 310 is a structure with a large top and a small bottom, which is helpful for the subsequent demoulding operation, and the design of the heat dissipation grooves 3120 is helpful for the cooling and solidification of the lithium liquid, and improves the quality of the lithium ingot. It should be noted that the heat dissipation grooves 3120 are located on the outer wall of the cylinder 310, and are annular grooves of different depths, which increase the heat dissipation area of ​​the mold body 300 in contact with the argon gas in the glove box for cooling, and improve the heat dissipation efficiency and consistency of the heat dissipation speed of various parts of the mold. Since the inner wall of the cylinder 310 is a conical structure with a large top and a small bottom, the overall material of the cylinder 310 is thin at the top and thick at the bottom, that is, there is a problem of uneven cooling speed of various parts of the cylinder 310. As a preferred embodiment, the depth of each heat dissipation groove 3120 is adapted and adjusted, so that various parts of the mold can dissipate heat at a more balanced speed, avoiding internal stress or quality defects caused by uneven cooling, thereby improving the quality and yield rate of the lithium ingot.

[0031] For further information, see Figure 1 and Fig.12The monitoring mechanism 500 is composed of a fixed plate 510 and a high liquid level electrode 520 and a low liquid level electrode 530 which are both installed on the fixed plate 510 in the vertical direction. The low liquid level electrode 530 and the high liquid level electrode 520 are both installed on the fixed plate 510, and are used to detect the height of lithium liquid casting, and have the ability to control the closing of the casting valve and the ability to control the emergency stop of the production line. Specifically, when the low liquid level electrode 530 fails, the lithium liquid continues to be cast to the high liquid level electrode 520, triggering the emergency stop procedure, and the casting stops. The casting needs to be restarted after the abnormality is handled.

[0032] For further information, see Figure 2 and Figure 5 , and further includes an auxiliary support seat 600 disposed outside the hinged end of the flap 2120, the auxiliary support seat 600 includes a fixing seat 610 fixedly mounted on the base 100, the top of the fixing seat 610 is provided with an arc groove 620 that fits the outer wall of the cylinder 310, and the top of the fixing seat 610 is glued and covered with a rubber pad 630. Among them, the auxiliary support seat 600 provides support for the inverted mold body 300, ensures the stability of the material removal, and further ensures the quality of the lithium ingot.
