Description

Technical Field

[0001] This utility model relates to the field of battery module packaging mold technology, and in particular to a battery module packaging mold with replaceable mold cavity. Background Technology

[0002] With the rapid development of new energy vehicles and energy storage industries, the packaging technology of battery modules has put forward higher requirements for production efficiency, cost control and product consistency. Traditional battery module packaging molds usually adopt a fixed cavity structure, which is only suitable for a single model of cell or module specification.

[0003] In the process of using battery module packaging molds, traditional battery module packaging molds usually use bolt or snap-fit ​​structures to securely install the mold cavity seat. When it is necessary to disassemble and replace the mold cavity seat, a large number of bolts need to be disassembled and installed one by one, which affects work efficiency.

[0004] Therefore, to address the aforementioned problem of inconvenient disassembly and replacement of the mold cavity seat, a battery module packaging mold with a replaceable mold cavity can be designed. During installation, the mold cavity seat automatically locks itself through the cooperation of the locking rod and the inclined surface, as well as the elastic action of the return spring. During disassembly, simply pulling one side of the locking rod will activate the entire locking mechanism, unlocking the mold cavity seat and making it easy to remove. This design greatly improves the flexibility and efficiency of the mold. Utility Model Content

[0005] In order to overcome the problem that bolts may loosen or come off during the use of battery module packaging molds, which may cause the mold cavity seat to loosen or shift during use, resulting in reduced packaging accuracy and unstable product quality, it is necessary to improve the mold cavity seat and make it inconvenient to disassemble and replace the mold cavity seat.

[0006] The technical solution of this utility model is as follows: a battery module packaging mold with replaceable mold cavity, including a mold base, a mounting groove, a mold cavity seat, a lower inclined surface, an upper inclined surface, a locking rod, a locking hole, a sliding ball, an adjustment cavity, a sliding plate, and a return spring. The mold base has a mounting groove inside, and the mold cavity seat is arranged inside the mounting groove. Two sets of lower inclined surfaces are arranged on both sides of the inner wall of the mounting groove. Two sets of upper inclined surfaces are arranged on both sides of the bottom wall of the mold cavity seat. Two sets of locking rods are slidably arranged inside both sides of the mold base. Two sets of locking holes are opened on both sides of the bottom wall of the mold cavity seat. One end of the locking rod is engaged with the inside of the locking hole. A sliding ball is rotatably arranged on one end of the locking rod. The mold base has an adjustment cavity inside, and two sets of sliding plates are arranged inside both sides of the adjustment cavity. A return spring is fixedly arranged on the upper inner wall of the sliding plate.

[0007] Preferably, during the use of the battery module packaging mold, when installing the mold cavity seat, the mold cavity seat is first vertically inserted into the mounting groove from the top of the mold base. At this time, the lower inclined surfaces of the bottom walls on both sides of the mold base are tightly fitted with the upper inclined surfaces of the inner walls on both sides of the mounting groove. During this process, the front end of the locking rod abuts against the upper inclined surface through the sliding ball. At this time, the return spring is compressed and deformed, storing force for the subsequent return movement, and providing elastic support and return force for the locking rod. Under the elastic action of the return spring, the front end of the locking rod can be driven to slide down into the locking hole through the sliding ball for locking, so that the mold cavity seat and the mounting groove are locked together, thereby achieving a stable installation of the mold cavity seat. The mold cavity seat is designed to be easily disassembled and replaced. When replacement is needed, the rear end of the locking rod is pulled outwards, disengaging the front end from the locking hole. This unlocks the mold cavity seat. Lifting the mold cavity seat upwards removes it from the mounting slot, allowing for quick disassembly. In summary, this mechanism enables convenient disassembly and replacement of the mold cavity seat. During installation, the mold cavity seat automatically locks itself through the locking rod's engagement with the inclined surface and the elasticity of the return spring. During disassembly, simply pulling one side of the locking rod activates the entire locking mechanism, unlocking the mold cavity seat and making it easy to remove. This design significantly improves the mold's flexibility and efficiency.

[0008] Preferably, the upper inclined surface and the lower inclined surface are in contact with each other, the upper end of the sliding plate is fixedly connected to the side wall of the locking rod, and one end of the return spring is fixedly connected to the inner wall of the adjustment cavity.

[0009] Preferably, two sets of adjustment cavities are provided inside both sides of the mold base, and guide parts are fixedly installed on the side wall of the locking rod, and two sets of guide rods are fixedly installed on the upper and lower sides of the adjustment cavity.

[0010] Preferably, the guide member is slidably connected to the guide rod, and two sets of guide springs are fixedly installed on the inner walls of the upper and lower sides of the guide member, with one end of the guide spring being fixedly connected to the inner wall of the adjustment cavity.

[0011] Preferably, two sets of sliding rods are fixedly installed on the inner walls of both sides of the adjustment cavity. The sliding rods are located inside the sliding plate, and the sliding plate and the sliding rods are slidably connected.

[0012] Preferably, an adjusting shaft is rotatably mounted on the right inner wall of the adjusting cavity, and an adjusting gear is fixedly mounted on the side wall of the adjusting shaft. Two sets of adjusting gear plates are mounted on both the upper and lower sides of the adjusting gear, and both sets of adjusting gear plates mesh with the upper and lower sides of the adjusting gear.

[0013] Preferably, the right end of the lower adjusting tooth plate is fixedly connected to the lower end of the right sliding plate, and a connecting plate is fixedly provided on the left end of the upper adjusting tooth plate, with the left end of the connecting plate fixedly connected to the lower end of the left sliding plate.

[0014] The beneficial effects of this utility model are:

[0015] During the use of the battery module packaging mold, when installing the mold cavity seat, firstly, the mold cavity seat is vertically inserted into the mounting groove from the top of the mold base. At this time, the lower inclined surfaces of the bottom walls on both sides of the mold base are tightly fitted with the upper inclined surfaces of the inner walls on both sides of the mounting groove. During this process, the front end of the locking rod abuts against the upper inclined surface through a sliding ball. At this time, the return spring is compressed and deformed, storing force for the subsequent return movement, and providing elastic support and return force for the locking rod. Under the elastic action of the return spring, the front end of the locking rod can be driven to slide down into the locking hole through the sliding ball and engage, so that the mold cavity seat and the mounting groove are locked together, thereby achieving a stable installation of the mold cavity seat. In effect, when the mold cavity seat needs to be replaced, firstly, pull the rear end of the locking rod outward, causing the front end of the locking rod to disengage from the inside of the locking hole. At this time, the mold cavity seat is unlocked. Then, lifting the mold cavity seat upward will disengage it from the inside of the mounting slot, thus achieving a quick disassembly of the mold cavity seat. In summary, through the above mechanism, the mold can achieve convenient disassembly and replacement of the mold cavity seat. During installation, the mold cavity seat is automatically locked by the cooperation of the locking rod and the inclined surface, as well as the elasticity of the return spring. During disassembly, only one side of the locking rod needs to be pulled to drive the entire locking mechanism to move, so that the mold cavity seat is unlocked and easily removed. This design greatly improves the flexibility and efficiency of the mold. Attached Figure Description

[0025] Please see Figure 1 and Figure 2 This utility model provides an embodiment: a battery module packaging mold with replaceable mold cavity, including a mold base 1, a mounting groove 2, a mold cavity seat 3, a lower inclined surface 4, an upper inclined surface 5, a locking rod 6, a locking hole 7, a sliding ball 8, an adjustment cavity 9, a sliding plate 10, and a return spring 11. The mold base 1 has a mounting groove 2 inside, and the mold cavity seat 3 is arranged inside the mounting groove 2. Two sets of lower inclined surfaces 4 are arranged on both sides of the inner wall of the mounting groove 2. Two sets of upper inclined surfaces 5 are arranged on both sides of the bottom wall of the mold cavity seat 3. Two sets of locking rods 6 are slidably arranged inside both sides of the mold base 1. Two sets of locking holes 7 are arranged on both sides of the bottom wall of the mold cavity seat 3. One end of the locking rod 6 is engaged with the inside of the locking hole 7. A sliding ball 8 is rotatably arranged on one end of the locking rod 6. The mold base 1 has an adjustment cavity 9 inside, and two sets of sliding plates 10 are arranged inside both sides of the adjustment cavity 9. A return spring 11 is fixedly arranged on the upper inner wall of the sliding plate 10.

[0026] Please see Figure 3 and Figure 4 The upper inclined surface 5 and the lower inclined surface 4 are in contact and connected. The upper end of the sliding plate 10 is fixedly connected to the side wall of the locking rod 6. One end of the return spring 11 is fixedly connected to the inner wall of the adjustment cavity 9. Under the elastic action of the return spring 11, the front end of the locking rod 6 can be driven to slide down through the ball 8 into the interior of the locking hole 7 for engagement, so that the mold cavity seat 3 and the mounting groove 2 are locked. Two sets of adjustment cavities 12 are opened on both sides of the mold base 1. A guide 13 is fixedly installed on the side wall of the locking rod 6. Two sets of guide rods 14 are fixedly installed on the upper and lower sides of the adjustment cavity 12. The locking rod 6 drives the guide 13 to slide along the guide rod 14.

[0027] Please see Figure 5 and Figure 7 The guide member 13 is slidably connected to the guide rod 14. Two sets of guide springs 15 are fixedly installed on the inner walls of the upper and lower sides of the guide member 13. One end of the guide spring 15 is fixedly connected to the inner wall of the adjustment cavity 12. When the guide spring 15 is squeezed, it deforms, storing force for the subsequent reset movement, and at the same time providing elastic support and reset force for the locking rod 6. Two sets of sliding rods 16 are fixedly installed on the inner walls of both sides of the adjustment cavity 9. The sliding rods 16 are located inside the sliding plate 10. The sliding plate 10 is slidably connected to the sliding rods 16. The locking rod 6 drives the sliding plate 10 to slide along the sliding rods 16.

[0028] Please see Figure 6 and Figure 7 An adjusting shaft 17 is rotatably mounted on the right inner wall of the adjusting cavity 9. An adjusting gear 18 is fixedly mounted on the side wall of the adjusting shaft 17. Two sets of adjusting gear plates 19 are mounted on the upper and lower sides of the adjusting gear 18. Both sets of adjusting gear plates 19 mesh with the upper and lower sides of the adjusting gear 18. The lower adjusting gear plate 19 can drive the upper adjusting gear plate 19 to slide to the left and outward through the adjusting gear 18. The right end of the lower adjusting gear plate 19 is fixedly connected to the lower end of the right sliding plate 10. A connecting plate 20 is fixedly mounted on the left end of the upper adjusting gear plate 19. The left end of the connecting plate 20 is fixedly connected to the lower end of the left sliding plate 10. The upper adjusting gear plate 19 can push the left sliding plate 10 to slide to the left and outward along the sliding rod 16 through the connecting plate 20. The left sliding plate 10 can drive the left locking rod 6 to slide to the left and outward.

[0029] When the battery module packaging mold is in use, when installing the mold cavity seat 3, firstly, the mold cavity seat 3 is vertically placed into the interior of the mounting groove 2 from the top of the mold base 1. At this time, the lower inclined surfaces 4 of the bottom walls on both sides of the mold base 1 are tightly fitted with the upper inclined surfaces 5 of the inner walls on both sides of the mounting groove 2.

[0030] During this process, the front end of the locking rod 6 is pressed against the upper inclined surface 5 through the sliding ball 8. The locking rod 6 drives the guide 13 to slide along the guide rod 14. In addition, the locking rod 6 drives the sliding plate 10 to slide along the sliding rod 16. At this time, the guide spring 15 and the return spring 11 are deformed by compression, which stores the force for the subsequent return movement and provides elastic support and return force for the locking rod 6.

[0031] Under the elastic action of the return spring 11 and the guide spring 15, the front end of the locking rod 6 can slide down through the ball bearing 8 into the interior of the locking hole 7 to engage, so that the mold cavity seat 3 and the mounting groove 2 are locked together, thereby achieving a stable installation effect on the mold cavity seat 3.

[0032] When the mold cavity seat 3 needs to be replaced, firstly, pull the rear end of the right locking rod 6 to the right outside, so that the front end of the right locking rod 6 disengages from the inside of the right locking hole 7. At the same time, the right sliding plate 10 and the lower adjusting tooth plate 19 can slide to the right outside along the sliding rod 16.

[0033] Since both sets of adjusting tooth plates 19 mesh with the upper and lower sides of the adjusting gear 18, the lower adjusting tooth plate 19 can drive the upper adjusting tooth plate 19 to slide to the left and outward through the adjusting gear 18. The upper adjusting tooth plate 19 can push the left sliding plate 10 to slide to the left and outward along the sliding rod 16 through the connecting plate 20. The left sliding plate 10 can drive the left locking rod 6 to slide to the left and outward, causing the front end of the left locking rod 6 to disengage from the inside of the left locking hole 7. At this time, the mold cavity seat 3 is unlocked. Then, lifting the mold cavity seat 3 upward can disengage it from the inside of the mounting groove 2, thereby achieving the effect of quick disassembly of the mold cavity seat 3.

[0034] In summary, through the above mechanism, the mold can achieve convenient disassembly and replacement of the mold cavity seat 3. During installation, the mold cavity seat 3 is automatically locked by the locking rod 6 cooperating with the inclined surface and the elastic action of the return spring 11. During disassembly, only one side of the locking rod 6 needs to be pulled to drive the entire locking mechanism to move, so that the mold cavity seat 3 can be unlocked and easily removed. This design greatly improves the flexibility and efficiency of the mold.

[0035] Through the above steps, when the battery module packaging mold is in use, during the installation of the mold cavity seat 3, firstly, the mold cavity seat 3 is vertically placed into the installation groove 2 from the top of the mold base 1. At this time, the lower inclined surfaces 4 of the bottom walls on both sides of the mold base 1 are tightly fitted with the upper inclined surfaces 5 of the inner walls on both sides of the installation groove 2. During this process, the front end of the locking rod 6 is pressed against the upper inclined surface 5 through the sliding ball 8. At this time, the return spring 11 is deformed by the compression, storing force for the subsequent reset movement, and providing elastic support and reset force for the locking rod 6. Under the elastic action of the return spring 11, the front end of the locking rod 6 can be driven to slide down through the sliding ball 8 into the locking hole 7 for locking, so that the mold cavity seat 3 and the installation groove 2 are locked together, thereby locking the mold cavity seat 3. To achieve a stable installation, when the mold cavity seat 3 needs to be replaced, firstly, pull the rear end of the locking rod 6 outward, causing the front end of the locking rod 6 to disengage from the inside of the locking hole 7. At this time, the mold cavity seat 3 is unlocked. Then, lifting the mold cavity seat 3 upward will allow it to disengage from the inside of the mounting groove 2, thus enabling quick disassembly of the mold cavity seat 3. In summary, through the above mechanism, the mold can achieve convenient disassembly and replacement of the mold cavity seat 3. During installation, the mold cavity seat 3 is automatically locked by the cooperation of the locking rod 6 and the inclined surface, as well as the elastic action of the return spring 11. During disassembly, only one side of the locking rod 6 needs to be pulled to drive the entire locking mechanism to move, so that the mold cavity seat 3 is unlocked and easily removed. This design greatly improves the flexibility and efficiency of the mold.
