Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to an automatic chip removal mechanism for battery casing molds. Background Technology

[0002] A battery mold shell is a mold tool used to manufacture battery shells. It is usually composed of components such as a mold base, core blank, mold core, mold cavity, and ejector pins. The mold base, as the main part of the mold, provides support and mounting foundation. The core blank and mold core are the forming molds for the negative and positive electrodes of the battery and are key parts in battery manufacturing. The mold cavity is responsible for forming the battery shell. Ejector pins are used to eject the battery during the forming process in the mold cavity.

[0003] Chinese Patent Publication No. CN222406745U discloses an automatic chip removal mechanism for battery casing molds. This mechanism includes a base plate, a pressing plate, a through groove, an injection molding plate, a rotating rod, an adjustable chip removal component, and a collection component. The collection component collects chips and impurities, preventing them from spreading in the air and ensuring the quality of subsequent battery casing processing. The adjustable chip removal component removes chips and impurities, keeping the inside of the injection molding plate clean and thus ensuring the quality of subsequent battery casing processing.

[0004] However, the above solutions suffer from several drawbacks. First, they are inefficient and cumbersome: the slide bar needs to be manually pulled, the rotating parts rotated, and the locking mechanism reset before the motor can be started. This process is complex, time-consuming, and reliant on manual precision. A 180-degree rotation and slide bar locking require manual alignment, and operational errors can lead to positional shifts, necessitating repeated adjustments. Second, the cleaning effect is limited due to insufficient vibration intensity: the mechanical impact between the cam and the chip removal plate may not generate high-frequency vibration, resulting in poor removal of highly adhesive impurities or fine debris. The coverage area is limited, and the vibration energy distribution is uneven. Dead corners inside the injection molded plate (such as narrow gaps and curved structures) may not be effectively cleaned. Finally, there are reliability issues with the equipment, including severe mechanical wear: components such as the cam and connecting rod are subjected to long-term impact loads, which can easily lead to fatigue fracture or deformation, increasing the failure rate. Spring fatigue failure and repeated stretching of the tension spring may cause it to lose elasticity, resulting in loose slide bar locking and affecting the stability after rotation. Utility Model Content

[0005] Based on the existing technical problems of low operating efficiency, cumbersome steps, limited cleaning effect, insufficient vibration intensity, equipment reliability issues, and severe mechanical wear in the descaling mechanism for battery casing molds, this utility model proposes an automatic descaling mechanism for battery casing molds.

[0006] This utility model proposes an automatic chip removal mechanism for battery casing molds, including a bracket, an upper mold assembly fixedly installed at the upper end of the bracket, and an adjustment device provided on the outer surface of the bracket. The adjustment device includes a support frame and a lower mold, and the movement of the support frame drives the lower mold to rise and fall.

[0007] The outer surface of the bracket is provided with a chip removal device, which includes a scraper that scrapes the debris from the inner wall of the lower mold.

[0008] Preferably, the adjusting device further includes a support frame, which is fixedly installed on the upper surface of the bracket. The outer surface of the support frame is slidably inserted into the outer surface of the support frame. The two ends of the lower mold are rotatably connected to the outer surfaces of the two support frames respectively. The upper surface of the lower mold is slidably inserted into one end of the fixing pin of the upper mold assembly.

[0009] The above technical solution allows the lower mold to rotate on the support frame, enabling it to face downwards when debris needs to be cleaned, facilitating cleaning by the scraper. The through-hole on the upper surface of the lower mold is inserted into the fixing pin of the upper mold assembly for positioning between the lower and upper molds during battery casing manufacturing, preventing the lower mold from rotating.

[0010] Preferably, an electric push rod is fixedly installed on the inner wall of the bracket, and a sliding groove frame is fixedly installed on one end of the push rod of the electric push rod. The outer surface of the sliding groove frame is slidably inserted into the inner wall of the bracket, and a roller is rotatably connected to the outer surface of the support frame. The outer surface of the roller is rotatably connected to the sliding groove of the sliding groove frame.

[0011] Through the above technical solution, in order to drive the upper mold to rise and then rotate, the slide frame is moved by the electric push rod. The trajectory of the groove in the slide frame drives the support frame to rise or fall within the support frame. The degree of descent is as high as the degree of rise, which makes it easier for the lower mold to be inserted into the support frame.

[0012] Preferably, a rotating rack is fixedly installed at the upper end of the slide frame, an insertion block is fixedly installed on the inner surface of the slide frame, rotating gears are fixedly installed at both ends of the lower mold, the rotating gears mesh with the rotating rack, and the insertion block is slidably inserted into the inner wall of the tooth groove of the rotating gear.

[0013] Through the above technical solution, in order to drive the lower mold to rotate, the movement of the slide frame drives the rotating rack to move, which in turn drives the rotating gear to rotate, thus driving the lower mold to rotate. This allows the debris inside the lower mold to fall off. The rotating gear can be inserted through the plug-in block to fix the rotating gear and prevent inaccurate positioning caused by the rotation of the lower mold during battery casing manufacturing.

[0014] Preferably, the chip removal device further includes a drive motor, which is fixedly installed on the inner wall of the support frame. A chip removal screw is rotatably connected to the inner wall of the support frame via a bearing. One end of the chip removal screw is fixedly installed to the output shaft of the drive motor via a coupling. A limit rod is fixedly installed on the inner wall of the support frame.

[0015] Through the above technical solution, the rotation of the chip removal screw driven by the drive motor can drive the scraper to move automatically, thereby scraping the inner wall of the lower mold. The width of the scraper is greater than the depth of the lower mold, which facilitates the comprehensive scraping of the inner wall of the lower mold. When the lower mold descends and rises, the insertion of the scraper can scrape the inner walls on both sides.

[0016] Preferably, the outer surface of the dander screw is threaded to one end of the scraper, the other end of the scraper is slidably inserted into the outer surface of the limiting rod, and both ends of the scraper are slidably inserted into the inner wall of the support frame.

[0017] Through the above technical solution, the outer surface of the scraper has a small, inclined scraper that can easily scrape the inner walls on both sides of the lower mold, reducing the residue of debris.

[0018] The beneficial effects of this utility model are as follows:

[0019] By setting up an adjustment device and a chip removal device, the inner wall of the lower mold can be automatically removed. The electric push rod pushes the slide frame to move, which in turn drives the support frame to rise and fall. The lower mold on the support frame rises, and at the same time, the movement of the slide frame drives the movement of the rotating rack, which in turn drives the rotating gear on the lower mold to rotate. This allows the mold opening of the lower mold to face downwards, making it easier for the scraper to move and clean the inside of the mold opening. Through the insertion between the lower mold and the support frame, the scraper can easily remove chips from the inside of the lower mold, thereby reducing manual labor. This solves the technical problems of low operating efficiency, cumbersome steps, limited cleaning effect, insufficient vibration intensity, equipment reliability issues, and severe mechanical wear in existing chip removal mechanisms for battery casing molds.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-7 An automatic chip removal mechanism for battery casing molds includes a support 1. An upper mold assembly 11 is fixedly installed on the upper end of the support 1. The upper mold assembly 11 is pushed down by a hydraulic cylinder. The upper mold assembly 11 consists of a hydraulic cylinder, an upper mold, a fixing pin, a spring, and a frame. An adjustment device is provided on the outer surface of the support 1. The adjustment device includes a support frame 21 and a lower mold 22. The movement of the support frame 21 drives the lower mold 22 to rise and fall.

[0030] Specifically, in order to rotate the lower mold 22 to adjust its position, the adjustment device also includes a support frame 2. The support frame 2 is fixedly installed on the upper surface of the bracket 1. The outer surface of the support frame 2 is slidably inserted into the outer surface of the support frame 21. The two ends of the lower mold 22 are rotatably connected to the outer surfaces of the two support frames 21 respectively. The upper surface of the lower mold 22 is slidably inserted into one end of the fixing pin of the upper mold assembly 11 to facilitate positioning of the lower mold 22.

[0031] The lower mold 22 is rotatably connected to the support frame 21 so that the lower mold 22 faces downward when it is necessary to clean debris, which is convenient for the scraper 43 to clean. The through hole opened on the upper surface of the lower mold 22 is inserted into the fixing pin of the upper mold assembly 11 to position the lower mold 22 and the upper mold when making the battery case, and to prevent the lower mold 22 from rotating.

[0032] Specifically, in order to automatically adjust the lower mold 22 for lifting and lowering, an electric push rod 23 is fixedly installed on the inner wall of the support 1. A slide rail frame 24 is fixedly installed at one end of the push rod of the electric push rod 23. The outer surface of the slide rail frame 24 is slidably inserted into the inner wall of the support 1. A roller 25 is rotatably connected to the outer surface of the support frame 21. The outer surface of the roller 25 is rotatably connected to the slide rail of the slide rail frame 24.

[0033] In order to drive the upper mold to rise and then rotate, the slide frame 24 is moved by the electric push rod 23. The track of the groove in the slide frame 24 drives the support frame 21 to rise or fall in the support frame 2. The degree of descent is as high as the degree of rise, so that the lower mold 22 can be inserted into the support frame 2.

[0034] Specifically, in order to drive the lower mold 22 to rotate, a rotating rack 3 is fixedly installed at the upper end of the slide frame 24, and a plug block 31 is fixedly installed on the inner surface of the slide frame 24. Rotating gears 32 are fixedly installed at both ends of the lower mold 22. The rotating gears 32 mesh with the rotating rack 3. In order to limit the rotation of the rotating gears 32, the plug block 31 slides into the inner wall of the tooth groove of the rotating gear 32.

[0035] In order to remove debris from the lower mold 22, a debris removal device is provided on the outer surface of the support 1. The debris removal device includes a scraper 43, which scrapes the debris on the inner wall of the lower mold 22.

[0036] Specifically, in order to automatically move the scraper 43, the chip removal device also includes a drive motor 4. The drive motor 4 is fixedly installed on the inner wall of the support frame 2. The support frame 2 is composed of a frame and a cover plate. The cover plate can be disassembled to facilitate maintenance of the internal mechanism. The inner wall of the support frame 2 is rotatably connected to the chip removal screw 41 through a bearing. One end of the chip removal screw 41 is fixedly installed to the output shaft of the drive motor 4 through a coupling. The inner wall of the support frame 2 is fixedly installed with a limit rod 42.

[0037] Specifically, the outer surface of the chip removal screw 41 is threaded to one end of the scraper 43, the other end of the scraper 43 is slidably inserted into the outer surface of the limiting rod 42, and both ends of the scraper 43 are slidably inserted into the inner wall of the support frame 2. The debris can be collected by a collection device on the bracket 1, such as a collection tank or a fan to suck up the scraped debris. This is the prior art.

[0038] By setting an adjustment device and a chip removal device, the inner wall of the lower mold 22 can be automatically removed. The electric push rod 23 pushes the slide frame 24 to move, which in turn drives the support frame 21 to rise and fall. The lower mold 22 on the support frame 21 rises. At the same time, the movement of the slide frame 24 drives the movement of the rotating rack 3, which drives the rotating gear 32 on the lower mold 22 to rotate. As a result, the mold opening of the lower mold 22 can face downward, which makes it easier for the scraper 43 to move and clean the mold opening. Through the insertion between the lower mold 22 and the support frame 2, the scraper 43 can easily remove the chips from the lower mold 22. This reduces the manual input and solves the technical problems of low operating efficiency, cumbersome steps, limited cleaning effect, insufficient vibration intensity, equipment reliability issues, and severe mechanical wear in the existing chip removal mechanism for battery shell molds.

[0039] Working principle: When it is necessary to remove debris from the lower mold 22, the electric push rod 23 on the bracket 1 is activated, which pushes the slide frame 24 to move. After the slide frame 24 moves, it pushes the roller 25 to move along the groove track, which drives the support frame 21 to rise, so that the lower mold 22 rises. At the same time, the insertion block 31 disengages from the tooth groove of the rotating gear 32. After the lower mold 22 rises, it drives the rotating gear 32 to connect with the rotating rack 3. The movement of the slide frame 24 drives the rotating rack 3 to move, and the rotation of the rotating gear 32 drives the lower mold 22 to rotate. After the lower mold 22 rotates 180 degrees, the mold opening of the lower mold 22 faces downward. After the slide frame 24 descends, it drives the support frame 21 to descend. After the scraper 43 scrapes against the inner wall of the lower mold 22, the top of the scraper 43 contacts the inner top wall of the lower mold 22. The drive motor 4 is activated, which drives the chip removal screw 41 to rotate. After the scraper 43 moves, it scrapes against the inner wall of the lower mold 22, so that the debris is scraped off and falls off.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
