Description

Technical Field

[0001] The present application relates to the technical field of copper busbars, and more specifically, to a one-time forming mold for producing copper busbars of battery modules. Background Art

[0002] Copper busbar, also known as copper busbar or copper busbar, is made of copper and is a long conductor with a rectangular or chamfered (rounded) rectangular cross-section (rounded copper busbars are generally used now to avoid tip discharge). It plays the role of transmitting current and connecting electrical equipment in the circuit.

[0003] During the production process of the battery module copper busbar, most of them are formed by hot extrusion, which makes the copper busbar easy to adhere to the mold during the manufacturing process, making it inconvenient for users to remove the copper busbar after production. Since the existing device itself cannot assist in demolding the copper busbar after production, it is necessary to manually demold the objects adhered to the mold, which will greatly affect the work efficiency of copper busbar production.

[0004] In order to solve the above problems, the present application provides a one-time molding mold for producing battery module copper bars. Utility Model Content

[0005] The present application provides a one-time forming mold for producing a battery module copper bar, which adopts the following technical solution:

[0006] A one-time forming mold for producing a battery module copper bar, comprising a base, an auxiliary mechanism is arranged inside the base, and the auxiliary mechanism extends to the outside of the base;

[0007] The auxiliary mechanism includes a groove, which is opened at the top of the base, and four airbags are fixedly embedded in the groove. The four airbags are symmetrically arranged in pairs with the center line of the base as the axis. A polyurethane spring is fixedly connected to the inner wall of the bottom of the base, and a lifting block is fixedly connected to the top of the polyurethane spring. A lower module is fixedly embedded on the inner side of the top of the base, and a sealing ring is fixedly embedded on the inner side of the lower module. The sealing ring is sleeved on the outside of the lifting block. An upper module is provided on the top of the lower module, and a buffer ring is fixedly connected to the top of the upper module. A connecting rod is fixedly embedded in the buffer ring, and a top seat is fixedly sleeved on the outer side of the top of the connecting rod, and a connecting component is provided on the outer side of the top seat.

[0008] Furthermore, the connecting component includes two pressure columns, the two pressure columns are respectively located between the two air bags, and the top ends of the two pressure columns extend to the top of the base.

[0009] Through the above technical solution, by providing two pressure columns, the top seat can be supported, so that the top seat can move up and down more smoothly.

[0010] Furthermore, two sleeves are fixedly connected to the top of the base, the two sleeves are symmetrically arranged with the center line of the base as the axis, and springs are fixedly embedded inside the two sleeves.

[0011] Through the above technical solution, by providing two springs, it is convenient for the user to press the top seat at a later time to complete the purpose of mold forming.

[0012] Furthermore, the two springs are respectively sleeved on the outside of the two pressure columns, the pressure column on one side is movably connected to the top seat through a hinge, and the top of the pressure column on the other side is fixedly connected with a connecting block.

[0013] Through the above technical solution, by setting the hinge, it is convenient for the user to rotate and open the top seat at a later time, and place the lowering mold on the top of the lower module.

[0014] Furthermore, a first magnet is fixedly connected to the inner side of the top of the connection block, and a second magnet is fixedly embedded in the bottom of the top seat.

[0015] Through the above technical solution, by setting the magnet one and the magnet two, the purpose of positioning the top seat can be achieved, so that the structure can be more stable when used.

[0016] Furthermore, the magnet one and the magnet two are respectively at the S level and the N level on the side close to each other, and the buffer ring is made of polyethylene foam plastic EPE.

[0017] Through the above technical solution, the service life of the mechanism can be improved because the polyethylene foam plastic EPE has the advantages of low density, good flexibility, high recovery rate, corrosion resistance and high temperature resistance.

[0018] In summary, this application includes the following beneficial technical effects:

[0019] After placing the mold on the top of the lower module, the mold is squeezed. During the extrusion process, the lifting block will move downward to squeeze the polyurethane spring. After the object is formed, the top seat is rotated upward, and the upper module is separated from the lower module. At this time, the polyurethane spring is not restricted. Because the polyurethane spring has high strength and good resilience, and has a long compression time, small deformation and good buffering, it can drive the lifting block to move upward to push out the molded object inside the lower module. Through the above structure, the problem that the equipment itself cannot assist in demolding the copper busbar after production by the equipment, and manual demolding of the objects adhered to the mold is required, which will greatly affect the work efficiency of making the copper busbar, is solved.

[0028] The present application embodiment discloses a one-time forming mold for producing a battery module copper bar. Figure 1 , Figure 2 and Figure 3 , comprising a base 1, an auxiliary mechanism is provided inside the base 1, and the auxiliary mechanism extends to the outside of the base 1;

[0029] The auxiliary mechanism includes a groove, which is opened at the top of the base 1. Four airbags 2 are fixedly embedded in the groove. The four airbags 2 are symmetrically arranged in pairs with the center line of the base 1 as the axis. A polyurethane spring 3 is fixedly connected to the inner wall of the bottom of the base 1. A lifting block 4 is fixedly connected to the top of the polyurethane spring 3. A lower module 5 is fixedly embedded on the inner side of the top of the base 1. A sealing ring 6 is fixedly embedded on the inner side of the lower module 5. The sealing ring 6 is sleeved on the outer side of the lifting block 4. An upper module 7 is provided on the top of the lower module 5. A buffer ring 8 is fixedly connected to the top of the upper module 7. A connecting rod 9 is fixedly embedded in the buffer ring 8. A top seat 10 is fixedly sleeved on the outer side of the top of the connecting rod 9.

[0030] See also Figure 2 and Figure 3 A connecting component is provided on the outside of the top seat 10, and the connecting component includes two pressure columns 11, which are respectively located between the two air bags 2, and the top ends of the two pressure columns 11 extend to the top of the base 1. Two sleeves 12 are fixedly connected to the top of the base 1, and the two sleeves 12 are symmetrically arranged with the center line of the base 1 as the axis. Springs 13 are fixedly embedded in the two sleeves 12. By providing two pressure columns 11, the top seat 10 can be supported, so that the top seat 10 can move up and down more smoothly. At the same time, by providing two springs 13, it is convenient for the user to press the top seat 10 later to complete the purpose of mold forming;

[0031] See also Figure 3 , two springs 13 are respectively sleeved on the outside of the two pressure columns 11, one side of the pressure column 11 is movably connected to the top seat 10 by a hinge, and the top of the other side of the pressure column 11 is fixedly connected to a connecting block 14, and the inner side of the top of the connecting block 14 is fixedly connected to a magnet 15, and the bottom of the top seat 10 is fixedly embedded with a magnet 2 16, and the side close to the magnet 15 and the magnet 2 16 are S level and N level respectively. The buffer ring 8 is made of polyethylene foam plastic EPE. By setting a hinge, it is convenient for the user to rotate and open the top seat 10 later and place the lowering mold on the top of the lower module 5. At the same time, by setting the magnet 15 and the magnet 2 16, the purpose of positioning the top seat 10 can be achieved, so that the structure can be more stable when used, and because the polyethylene foam plastic EPE has the advantages of low density, good flexibility, high recovery rate and corrosion resistance and high temperature resistance, it can improve the service life of the mechanism.

[0032] The implementation principle of this embodiment is: first, the top seat 10 is rotated upward and opened through the hinge, and after the mold is placed on the top of the lower module 5, the top seat 10 and the upper module 7 are matched through the hinge to squeeze the mold. Since the magnet 15 and the magnet 2 16 are in an attractive state, the connection between the upper module 7 and the lower module 5 can be made more stable. During the squeezing process, the two springs 13 and the two air bags 2 at the bottom will be in a compressed state, and the lifting block 4 will move downward to squeeze the polyurethane spring 3. Since the sealing ring 6 is provided, the connection between the lifting block 4 and the lower module 5 can be strengthened. After the object is formed, the top seat 10 can be rotated upward by the hinge to separate the magnet 15 from the magnet 2 16, and then the upper module 7 is separated from the lower module 5. At this time, the polyurethane spring 3 is not restricted. Since the polyurethane spring 3 has high strength and good resilience, and has a long compression time, small deformation and good buffering performance, it can drive the lifting block 4 to move upward to push out the formed object inside the lower module 5. Through the above structure, the problem that the equipment itself cannot assist in demolding the copper busbar after production by the equipment, and manual demolding of the objects adhered to the mold is required, which greatly affects the work efficiency of making the copper busbar, is solved.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
