Description

Technical Field

[0001] This utility model relates to the field of casting molds, and in particular to an aluminum anode cooling mold for aluminum-air batteries. Background Technology

[0002] Aluminum-air batteries are a new type of high-energy-density battery. They use high-purity aluminum as the negative electrode (anode), oxygen as the positive electrode, and potassium hydroxide or sodium hydroxide aqueous solution as the electrolyte. Aluminum absorbs oxygen from the air and undergoes a chemical reaction during battery discharge, where aluminum reacts with oxygen to transform into aluminum oxide.

[0003] High-purity aluminum is used as the aluminum anode, which is made by pressing together multiple aluminum plates, which are usually cast from liquid aluminum. Our laboratory often uses a small metal melting furnace to produce small batches of aluminum plates. The melting furnace pours the aluminum solution into a cooling mold, and after the mold cools, the aluminum plates are removed from the mold.

[0004] Existing cooling molds in the laboratory, such as Figure 1 As shown, it consists of two symmetrical shells 10 and a clamping mechanism 20. The upper opening is used to pour in molten aluminum. Since the two shells are aligned manually, misalignment is easy to occur. When misalignment occurs, marks caused by mold gaps will appear on the side and bottom of the aluminum plate after cooling. Mold misalignment may even cause molten aluminum to leak out. Utility Model Content

[0005] In order to solve the problems in the prior art, this utility model provides an aluminum anode cooling mold for aluminum-air batteries.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A cooling mold for aluminum anodes in an aluminum-air battery includes a first shell and a second shell. The bottom of the second shell is provided with a horizontal base plate. The lower end of the first shell rests against the base plate. The first shell and the second shell are joined together to form a cavity in the middle. The upper end of the cavity is open, and molten aluminum enters the cavity from the upper end.

[0008] A locking mechanism is provided between the first housing and the second housing to achieve the clamping, fixing and separation of the first housing and the second housing.

[0009] Furthermore, the locking mechanism includes a first pin fixedly disposed on the left and right sides of the outside of the first housing, and a second pin fixedly disposed on the left and right sides of the outside of the second housing, wherein the first pin is positioned higher than the second pin in the longitudinal direction.

[0010] A rotating blade is rotatably sleeved on the first pin, and the rotating blade can be axially installed or removed from the first pin; a sliding groove adapted to the second pin is opened on the rotating blade, and the sliding groove is connected from top to bottom to a self-locking section, an arc section and a horizontal straight section; the arc section is not an arc-shaped structure with the center of the first pin as the center, and the center line of the self-locking section is closer to the direction of the first pin than the center line of the arc section.

[0011] When the second pin enters the self-locking section from the arc segment, it will pull the first housing and the second housing closer together. At this time, the force between the first pin and the second pin will cause the first housing to be subjected to an oblique pulling force, and the first housing will press down and towards the second housing at the same time.

[0012] When the second pin is in the straight section, the first housing is pulled to make the second pin slide along the straight section, thereby separating the first housing from the second housing.

[0013] Furthermore, the slide has a protrusion in the self-locking section, and the second pin is blocked by the protrusion after sliding into the self-locking section and cannot move in the opposite direction.

[0014] Furthermore, the rotating blade does not exceed the bottom edge of the second housing during rotation.

[0015] Furthermore, the locking mechanism is located at the lower part of the mold.

[0016] Furthermore, it also includes clamping mechanisms, of which there are two, located on the left and right sides of the mold respectively;

[0017] The clamping mechanism includes a C-shaped component and a bolt. One end of the C-shaped component is welded to the second housing, and the other end is welded to a nut. The bolt passes through the nut and abuts against the first housing, thereby clamping the first housing and the second housing.

[0018] Furthermore, the clamping mechanism is located at the top of the mold.

[0019] Furthermore, the two sides of the first shell that come into contact with the second shell have a stepped structure, and the most prominent surface is the joint surface of the two shells, which is closest to the cavity.

[0020] Furthermore, the remaining stepped surfaces of the stepped structure are fixedly provided with a sealing layer, which is elastic and protrudes more than the bonding surface.

[0021] Furthermore, the sealing layer is made of a high-temperature resistant material.

[0022] The beneficial effects of this utility model are:

[0023] Compared to the existing technology where the two shells are completely symmetrical, this technical solution extends the bottom of the second shell and removes the bottom of the first shell, so that the bottom surface of the aluminum plate remains completely flat after cooling. At the same time, the base plate also serves as the reference surface for the installation of the first shell, reducing longitudinal installation errors.

[0024] In this invention, the installation of the rotating blades on both sides is equivalent to lateral positioning of the two housings, reducing lateral installation errors. Simultaneously, when the rotating blades self-lock, the first housing is subjected to an oblique force, fully pressing it against the second housing to prevent leakage of molten aluminum.

[0032] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0034] like Figures 2 to 7 As shown, this embodiment provides an aluminum anode cooling mold for aluminum-air batteries, including a first shell 1 and a second shell 2. The bottom of the second shell 2 is provided with a horizontal base plate 21. The lower end of the first shell 1 abuts against the base plate 21. After the first shell 1 and the second shell 2 are combined, a cavity is formed in the middle. The upper end of the cavity is open, and the aluminum solution enters the cavity from the upper end.

[0035] Compared to the existing technology where the two shells are completely symmetrical, this technical solution extends the bottom of the second shell 2 and removes the bottom of the first shell 1, so that the bottom surface of the aluminum plate remains completely flat after cooling. At the same time, the base plate 21 also serves as the reference surface for the installation of the first shell 1, reducing longitudinal installation errors.

[0036] The two sides of the first shell 1 and the second shell 2 that are in contact with each other are stepped structures. The most prominent surface is the joint surface 7 of the two shells. The joint surface 7 is closest to the cavity. The remaining stepped surfaces are fixedly provided with a sealing layer 8. The sealing layer 8 is elastic and more prominent than the joint surface.

[0037] The sealing layer 8 is made of a high-temperature resistant material. The high-temperature resistant material must be elastic and its upper temperature limit must be higher than that of the aluminum solution.

[0038] A locking mechanism is provided between the first housing 1 and the second housing 2, which enables the first housing 1 and the second housing 2 to be pressed, fixed and separated.

[0039] The quick-locking mechanism is located at the lower part of the mold and includes a first pin 31 fixedly installed on the left and right sides of the outside of the first housing 1, and a second pin 32 fixedly installed on the left and right sides of the outside of the second housing 2. The first pin 31 is positioned higher than the second pin 32 in the longitudinal direction.

[0040] A rotating plate 33 is rotatably sleeved on the first pin 31, and the rotating plate 33 can be axially installed or removed from the first pin 31. The rotating plate 33 has a sliding groove adapted to the second pin 32, and the sliding groove is connected from top to bottom to a self-locking section 4, an arc section 5, and a horizontal straight section 6; wherein the arc section 5 is not an arc-shaped structure with the center of the first pin as the center, and the center line of the self-locking section 4 is closer to the first pin 31 than the center line of the arc section.

[0041] When the second pin 32 enters the self-locking section 4 from the arc segment 5, it will pull the first housing 1 and the second housing 2 closer together, and at the same time squeeze the sealing layer 8, so that the mating surface 7 contacts the second housing 2.

[0042] To prevent the second pin 32 from disengaging from the self-locking section 4, a protrusion 41 is provided in the self-locking section 4. After the second pin 32 slides into the self-locking section 4, it is obstructed by the protrusion 41 and cannot move in the reverse direction. At this time, the force between the first pin 31 and the second pin 32 causes the first housing 1 to be subjected to an oblique pulling force, and the first housing 1 is simultaneously pressed downward and towards the second housing 2. Because the first housing 1 is subjected to an oblique force, it is fully pressed towards the second housing 2, which can prevent the leakage of molten aluminum.

[0043] When the second pin 32 is inside the straight section 6, the first housing 1 is pulled to make the second pin 32 slide along the straight section 6, thereby separating the first housing 1 from the second housing 2.

[0044] In addition, it is necessary to ensure that the rotating blade 33 does not exceed the bottom edge of the second housing 2 during rotation, so as to avoid interference with the mold placement platform.

[0045] This invention, through the setting of a locking mechanism, allows the rotating blade 33 to both lock the first housing 1 and the second housing 2, and to quickly release the aluminum plate. When releasing the aluminum plate after the mold has cooled, the rotating blade 33 can also be directly removed axially from the first pin 31, thereby eliminating the tension between the first housing 1 and the second housing 2.

[0046] Meanwhile, the installation of the two rotating plates 33 in the locking mechanism is equivalent to lateral positioning of the two housings, reducing lateral installation errors.

[0047] In this embodiment, a clamping mechanism 9 is also provided on the upper part of the mold. There are two clamping mechanisms 9, which are located on the left and right sides of the mold respectively.

[0048] The clamping mechanism 9 includes a C-shaped part 91 and a bolt 92. One end of the C-shaped part 91 is welded to the second housing 2, and the other end is welded to a nut. The bolt 92 passes through the nut and abuts against the first housing 1, so that the first housing 1 and the second housing 2 are clamped together.

[0049] In this embodiment, the locking mechanism and the clamping mechanism are used simultaneously. In other embodiments, the locking mechanism may be used alone.
