Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for the outer shell of a portable energy storage device. Background Technology

[0002] With the development of technology, people have higher and higher requirements for energy storage devices. Many portable energy storage devices, namely portable power supplies, have appeared on the market, which better meet the needs of daily travel. In the production process of portable energy storage devices, it is necessary to manufacture their outer shell to ensure the strength of the device and protect the internal components.

[0003] Existing technologies have the following problems: After extensive searching, it was found that the patent document with application number CN202222834819.0 discloses a mold for the outer shell of a portable energy storage device. After the device is in operation, the second hydraulic rod can be pushed out to place the moving wheels on the ground and lift the device to move. At this time, the moving wheels can move the device flexibly. Based on the integration of all the equipment into one unit, the flexibility of its movement is improved, making it easier to carry and use the device.

[0004] However, the aforementioned patents still have some problems in actual use. The most obvious problem is that although they have a portable effect, it is difficult to change the molds of different specifications according to the processing requirements when processing the shell of the energy storage device. This makes it difficult to process energy storage device shells of different specifications, resulting in a limited range of compatibility.

[0005] To address these shortcomings, we propose a portable energy storage device casing mold. Utility Model Content

[0006] The purpose of this utility model is to provide a portable energy storage device shell mold in order to overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a portable energy storage device shell mold, comprising a frame, a hydraulic cylinder and a hydraulic pump station fixedly mounted on the top surface of the frame, a lifting frame mounted on the telescopic end of the hydraulic cylinder via a mounting plate, and an upper mold detachably mounted on the lifting frame, a support frame fixedly mounted on the frame, and a lower mold detachably mounted on the support frame, both the lifting frame and the support frame having an installation chamber inside, and a servo motor, a gear, a rack and pinion and a limiting spring installed inside the installation chamber, a worm gear mounted on the output end of the servo motor, a worm wheel coaxially mounted on the gear and meshing with the worm gear, one end of the limiting spring being fixedly connected to one end of the rack, and locking holes being opened on the outer walls of both the upper and lower molds, the other end of the rack being inserted into the locking hole, and the gear meshing with the rack.

[0008] Preferably, the lower mold has an inner bottom surface with a receiving groove, and the inner wall of the receiving groove is provided with a sealing ring. The receiving groove is provided with a feeding plate, and the bottom surface of the feeding plate is fixedly connected to a push rod. One end of the push rod extends to the lower part of the support frame and is provided with a push plate. A return spring is fixedly connected between the push plate and the support frame.

[0009] Preferably, the ends of the upper and lower molds that are far apart from each other are trapezoidal structures.

[0010] Preferably, the bottom surface of the frame is fixedly equipped with self-locking casters, and there are multiple self-locking casters, which are distributed in pairs on both sides of the bottom surface of the frame.

[0011] Preferably, the end of the rack near the lock hole has a wedge-shaped structure.

[0012] Preferably, the top surface of the feeding plate and the opening of the receiving groove are on the same horizontal line.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, a servo motor is set up to drive the worm gear to rotate in both directions. The rotation of the worm gear drives the worm wheel to rotate, and the rotation of the worm wheel drives the gear installed on the same axis to rotate accordingly, thereby realizing the left and right movement of the rack. When one end of the rack is inserted into the lock hole, it completes the locking and fixing of the upper and lower molds. After one end of the rack is removed from the lock hole, the mold can be disassembled by pulling the mold up and down. This is conducive to changing molds of different specifications according to different processing needs, meeting diverse processing requirements, and making the application range wider.

[0014] 2. In this utility model, the return spring is compressed and deformed by pressing the push plate to store energy. When the push plate moves up, it pushes the unloading plate up through the push rod, which can push the processed energy storage device shell out of the lower mold. Conversely, when the return spring releases its elastic potential energy, it drives the push plate to return to its original position, ready for the next use. This is beneficial for unloading and is a clever design that is worth promoting. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0020] Please refer to Figure 1-4 A portable energy storage device housing mold includes a frame 1. The frame 1 has a hydraulic cylinder 2 and a hydraulic pump station 3 fixedly mounted on its top surface. A lifting frame 4 is mounted on the telescopic end of the hydraulic cylinder 2 via a mounting plate. An upper mold 5 is detachably mounted on the lifting frame 4. A support frame 20 is fixedly mounted on the frame 1, and a lower mold 6 is detachably mounted on the support frame 20. Both the lifting frame 4 and the support frame 20 have internal installation chambers. A servo motor 10, a gear 13, a rack 8, and a limiting spring 9 are installed inside the installation chambers. A worm gear 11 is mounted on the output end of the servo motor 10. A worm wheel 12 is coaxially mounted on the gear 13 and meshes with the worm gear 11. One end of the limiting spring 9 is fixedly connected to one end of the rack 8. Locking holes 7 are provided on the outer walls of both the upper mold 5 and the lower mold 6. The other end of the rack 8 is inserted into the locking hole 7, and the gear 13 meshes with the rack 8.

[0021] By setting a servo motor 10, the servo motor 10 drives the worm gear 11 to rotate in both directions. The rotation of the worm gear 11 drives the worm wheel 12 to rotate. The rotation of the worm wheel 12 drives the gear 13, which is installed on the same axis, to rotate. This enables the rack 8 to move left and right. When one end of the rack 8 is inserted into the locking hole 7, it locks and fixes the upper mold 5 and the lower mold 6. After one end of the rack 8 is removed from the locking hole 7, the mold can be disassembled by pulling the mold up and down. This is beneficial for changing molds of different specifications according to different processing needs, meeting diverse processing requirements and making the application range wider. When the raw material is placed in the lower mold 6, the hydraulic cylinder 3 extends, causing the upper mold 5 and the lower mold 6 to close, completing the processing of the energy storage device shell. It should be noted that in order to ensure the smooth processing of the energy storage device shell, the heating of the raw material adopts a common method in the existing technology, which will not be described in detail here.

[0022] In this embodiment: the inner bottom surface of the lower mold 6 is provided with a receiving groove 14, and the inner wall of the receiving groove 14 is provided with a sealing ring 15. The receiving groove 14 is provided with a feeding plate 16, and the bottom surface of the feeding plate 16 is fixedly connected with a push rod 17. One end of the push rod 17 extends to the lower part of the support frame 20 and is provided with a push plate 18. A return spring 19 is fixedly connected between the push plate 18 and the support frame 20.

[0023] Specifically, by pressing the push plate 18, the return spring 19 is compressed and deformed to store energy. The push plate 18 moves upward and pushes the unloading plate 16 upward through the push rod 17, which can push the processed energy storage device shell out from the lower mold 6. Conversely, the return spring 19 releases its elastic potential energy to drive the push plate 18 to reset, waiting for the next use. This is beneficial for unloading and is a clever design that is worth promoting.

[0024] In this implementation plan, the ends of the upper mold 5 and the lower mold 6 that are far apart from each other are both trapezoidal structures.

[0025] Specifically, it serves as a guide during installation, facilitating the installation of the upper mold 5 and the lower mold 6 onto the lifting frame 4 and the support frame 20, respectively.

[0026] In this implementation plan: a number of self-locking casters are fixedly installed on the bottom surface of the frame 1, and the casters are distributed in pairs on both sides of the bottom surface of the frame 1.

[0027] Specifically, the self-locking casters allow for flexible movement of the device, enhancing its mobility and making it easier to carry and use, based on the integration of all equipment into one unit.

[0028] In this implementation scheme: the end of the rack 8 near the lock hole 7 is a wedge-shaped structure.

[0029] Specifically, the locking process is smoother, while there is a certain degree of error in the operation of the two.

[0030] In this embodiment, the top surface of the feeding plate 16 and the opening of the receiving groove 14 are on the same horizontal line.

[0031] Specifically, this reduces the impact on processing, resulting in a more aesthetically pleasing outer casing for the processed energy storage equipment.

[0032] Working principle: In use, a servo motor 10 drives the worm gear 11 to rotate in both directions. The rotation of the worm gear 11 drives the worm wheel 12 to rotate, which in turn drives the coaxially mounted gear 13 to rotate, thereby realizing the left and right movement of the rack 8. When one end of the rack 8 is inserted into the locking hole 7, it locks and fixes the upper mold 5 and the lower mold 6. After one end of the rack 8 is removed from the locking hole 7, the mold can be disassembled by pulling it up and down. This allows for the replacement of molds of different specifications according to different processing needs, satisfying multiple requirements. This design caters to a wider range of processing needs. The raw material is placed in the lower mold 6, and the hydraulic cylinder 3 extends, causing the upper mold 5 and lower mold 6 to close, thus completing the processing of the energy storage device's outer shell. By pressing the push plate 18, the return spring 19 is compressed and deformed to store energy. The push plate 18 moves upward, pushing the unloading plate 16 upward via the push rod 17, which ejects the processed energy storage device's outer shell from the lower mold 6. Conversely, the return spring 19 releases its elastic potential energy, driving the push plate 18 to return to its original position, ready for the next use. This design is ingenious and worthy of promotion.

[0033] 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.
