Description

Technical Field

[0001] This utility model relates to the field of injection mold cooling technology, specifically a high-efficiency cooling structure for an aluminum shell injection mold for power batteries. Background Technology

[0002] Injection molds are tools for producing plastic products, and also tools for giving plastic products their complete structure and dimensions. Currently, the production of battery casings mainly relies on injection molds. In the original design of battery casing plastic molds, a cooling structure was required to cool the aluminum casing of the power battery.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, if a large amount of heat cannot be dissipated in time after the aluminum battery shell is formed, the remaining heat will cause the battery shell to deform severely, affecting its appearance. At the same time, when manually retrieving the shell, the operator needs to put their hands and tools into the equipment, which makes the retrieval inconvenient and makes the production progress uncontrollable. It is also inconvenient to retrieve the cooled aluminum shell, resulting in low practicality.

[0004] To address the aforementioned problems, the inventors proposed a high-efficiency cooling structure for injection molds of aluminum casings for power batteries. Utility Model Content

[0005] To address the problems of inconvenience in cooling the outer surface of the aluminum casing of a power battery and inconvenience in retrieving the cooled aluminum casing, the purpose of this utility model is to provide a highly efficient cooling structure for the injection mold of the aluminum casing of a power battery.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a high-efficiency cooling structure for an aluminum shell injection mold of a power battery, comprising a cooling box, a retrieval component provided on the outer surface of the cooling box, a cooling component fixedly connected to the bottom surface of the cooling box, the cooling component comprising a protective shell, the top surface of the protective shell fixedly connected to the cooling box, a first motor fixedly connected to one side of the protective shell, the output end of the first motor extending into the protective shell and fixedly connected to a first rotating shaft, two first bevel gears fixedly sleeved on the outer surface of the first rotating shaft, a second bevel gear meshing with the outer surface of the first bevel gears, a second rotating shaft fixedly connected to the top surface of the second bevel gears, and multiple stirring rollers fixedly connected to the outer surface of the second rotating shaft.

[0007] As a preferred technical solution of this application, the salvage assembly includes two symmetrically distributed fixed plates. One side of the fixed plate is fixedly connected to a cooling tank. A lead screw is rotatably connected to the top surface of one of the fixed plates, and a second motor is fixedly connected to the bottom surface of the other fixed plate. The output end of the second motor extends into the fixed plate and is fixedly connected to the lead screw. A guide rod is fixedly connected to the top surface of the other fixed plate. Slider blocks are provided on both sides of the cooling tank. One slider is threadedly connected to the lead screw, and the other slider is movably connected to the guide rod. A tank cover is fixedly connected between the two sliders. A plurality of connecting rods arranged in a rectangular array are fixedly connected to the bottom surface of the tank cover, and a screen plate is fixedly connected to the bottom surface of the connecting rods.

[0008] With the above technical solution, after the aluminum shell has cooled, the output of the second motor is started to transmit power to the lead screw fixedly connected to it, causing the lead screw to rotate on the fixed plate. Since one slider is threadedly connected to the lead screw and the other slider is movably connected to the guide rod, and the two sliders are fixedly connected by the box cover, when the lead screw rotates, it will drive the slider to move vertically upward along the lead screw and the guide rod, causing the screen plate to rise synchronously. During the rise of the screen plate, the aluminum shell that has been cooled in the cooling box can be picked up from the cooling medium. The mesh structure of the screen plate can filter out the excess cooling medium attached to the surface of the aluminum shell, so that the aluminum shell can be quickly removed from the cooling environment, which can facilitate the retrieval of the cooled aluminum shell and improve production efficiency.

[0009] As a preferred technical solution of this application, a control panel is fixedly connected to one side of the cooling box.

[0010] The control panel can control the device using the above technical solution.

[0011] As a preferred technical solution of this application, the bottom surface of the cooling box is fixedly connected with support legs.

[0012] The above technical solution provides support for the cooling box via the support legs.

[0013] As a preferred technical solution of this application, the lower part of the cooling box is connected to a drain pipe, and the outer surface of the drain pipe is provided with a valve.

[0014] The above technical solution involves opening the valve on the outer surface of the drain pipe to discharge the cooling medium from the cooling tank for subsequent replacement.

[0015] As a preferred technical solution of this application, the two first bevel gears are distributed in opposite directions.

[0016] Through the above technical solution, the second rotating shaft rotates in the opposite direction inside the cooling box.

[0017] As a preferred technical solution of this application, a limiting plate is fixedly connected to the top end of the lead screw and the guide rod.

[0018] The above technical solution limits the position of the box lid using a limiting plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention can drive two second bevel gears to rotate synchronously in opposite directions when the first bevel gear rotates, thereby driving the second rotating shaft fixedly connected to the top surface of the second bevel gear and multiple stirring rollers on the outer surface to rotate. The stirring rollers rotate inside the cooling box, which can fully stir the cooling medium in the box, so that the temperature of the cooling medium is evenly distributed, and the heat exchange rate between the cooling medium and the aluminum shell is accelerated, thereby achieving the purpose of cooling the outer surface of the aluminum shell of the power battery. This invention utilizes the principle that when the lead screw rotates, it drives the slider to move vertically upward along the lead screw and guide rod, causing the screen plate to rise synchronously. During the upward movement of the screen plate, the cooled aluminum shell inside the cooling box can be retrieved from the cooling medium. The mesh structure of the screen plate can filter out excess cooling medium adhering to the surface of the aluminum shell, allowing the aluminum shell to quickly leave the cooling environment. This achieves the goal of conveniently retrieving the cooled aluminum shell and improving production efficiency. Attached Figure Description

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.

[0027] Example: Figure 1-4 As shown, this utility model provides a high-efficiency cooling structure for an aluminum shell injection mold of a power battery, including a cooling box 1, a control panel 4 fixedly connected to one side of the cooling box 1, a support leg 5 fixedly connected to the bottom surface of the cooling box 1, a drain pipe 6 connected to the lower part of the cooling box 1, a valve 7 provided on the outer surface of the drain pipe 6, a retrieval component 3 provided on the outer surface of the cooling box 1, and a cooling component 2 fixedly connected to the bottom surface of the cooling box 1. The cooling assembly 2 includes a protective shell 21. The top surface of the protective shell 21 is fixedly connected to the cooling box 1. A first motor 23 is fixedly connected to one side of the protective shell 21. The output end of the first motor 23 extends into the protective shell 21 and is fixedly connected to a first rotating shaft 22. Two first bevel gears 24 are fixedly sleeved on the outer surface of the first rotating shaft 22. The two first bevel gears 24 are distributed in opposite directions. A second bevel gear 25 is meshed with the outer surface of the first bevel gear 24. A second rotating shaft 26 is fixedly connected to the top surface of the second bevel gear 25. A plurality of stirring rollers 27 are fixedly connected to the outer surface of the second rotating shaft 26.

[0028] When the first bevel gear 24 rotates, it drives the two second bevel gears 25 to rotate synchronously in opposite directions, which in turn drives the second rotating shaft 26 fixedly connected to the top surface of the second bevel gear 25 and the multiple stirring rollers 27 on the outer surface to rotate. The stirring rollers 27 rotate inside the cooling box 1, which can fully stir the cooling medium in the box.

[0029] The salvage assembly 3 includes two symmetrically distributed fixed plates 31. One side of the fixed plate 31 is fixedly connected to the cooling box 1. A lead screw 32 is rotatably connected to the top surface of one fixed plate 31, and a second motor 33 is fixedly connected to the bottom surface of the other fixed plate 31. The output end of the second motor 33 extends into the fixed plate 31 and is fixedly connected to the lead screw 32. A guide rod 34 is fixedly connected to the top surface of the other fixed plate 31. A limit plate 35 is fixedly connected to the top end of the lead screw 32 and the guide rod 34. Slider blocks 36 are provided on both sides of the cooling box 1. One slider 36 is threadedly connected to the lead screw 32, and the other slider 36 is movably connected to the guide rod 34. A box cover 37 is fixedly connected between the two sliders 36. A plurality of connecting rods 38 distributed in a rectangular array are fixedly connected to the bottom surface of the box cover 37. A screen plate 39 is fixedly connected to the bottom surface of the connecting rods 38.

[0030] When the lead screw 32 rotates, it drives the slider 36 to move vertically upward along the lead screw 32 and the guide rod 34, causing the screen plate 39 to rise synchronously. During the rising process of the screen plate 39, the aluminum shell that has been cooled in the cooling box 1 can be taken out from the cooling medium.

[0031] The working principle of the high-efficiency cooling structure of the injection mold for the aluminum shell of the power battery in this embodiment is as follows: When the aluminum shell of the power battery needs to be cooled, the output end of the first motor 23 is started to transmit power to the first rotating shaft 22 fixedly connected to it, which drives the first rotating shaft 22 to rotate between the inner walls of the two sides of the protective shell 21. Since the two first bevel gears 24 fixedly sleeved on the outer surface of the first rotating shaft 22 are distributed in opposite directions and mesh with the second bevel gear 25, when the first bevel gear 24 rotates, it will drive the two second bevel gears 25 to rotate synchronously in opposite directions, thereby driving the second rotating shaft 26 fixedly connected to the top surface of the second bevel gear 25 and the multiple stirring rollers 27 on the outer surface to rotate. The stirring rollers 27 rotate inside the cooling box 1, which can fully stir the cooling medium in the box, so that the temperature of the cooling medium is evenly distributed, and the heat exchange rate between the cooling medium and the aluminum shell is accelerated, thereby achieving the purpose of effectively cooling the outer surface of the aluminum shell of the power battery. After the aluminum shell has cooled down, the output of the second motor 33 is started to transmit power to the lead screw 32, which is fixedly connected to it. The lead screw 32 rotates on the fixed plate 31. Since one of the sliders 36 is threadedly connected to the lead screw 32 and the other slider 36 is movably connected to the guide rod 34, and the two sliders 36 are fixedly connected by the box cover 37, when the lead screw 32 rotates, it will drive the slider 36 to move vertically upward along the lead screw 32 and the guide rod 34, which will drive the screen plate 39 to rise synchronously. During the rise of the screen plate 39, the aluminum shell that has been cooled in the cooling box 1 can be taken out of the cooling medium. The mesh structure of the screen plate 39 can filter out the excess cooling medium attached to the surface of the aluminum shell, so that the aluminum shell can be quickly removed from the cooling environment, thereby achieving the purpose of conveniently taking out the cooled aluminum shell and improving production efficiency. After cooling is complete, the valve 7 on the outer surface of the drain pipe 6 can be opened to drain the cooling medium in the cooling tank 1 for subsequent replacement. The support leg 5 provides stable support for the entire equipment, ensuring the stability of the equipment during operation.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
