Description

Technical Field

[0001] This utility model relates to the field of button battery sealing ring production technology, specifically a zinc-air button battery sealing ring injection mold. Background Technology

[0002] Sealing rings play a crucial sealing role in batteries. Zinc-air batteries contain electrolyte, and if the electrolyte leaks, it will not only affect the battery's performance but may also damage the equipment used and even threaten personal safety. Therefore, the presence of sealing rings is key to ensuring the battery's airtightness. Injection molds are used to mold the sealing rings during production.

[0003] Currently, after injection molding the sealing ring using a zinc-air button cell battery sealing ring injection mold, there is a lack of heat dissipation for the sealing ring. Due to the high temperature after injection molding, the sealing ring cannot be quickly unloaded. Furthermore, the gate of the current zinc-air button cell battery sealing ring is located in the middle of the outer wall of the sealing ring, and the gate has a slight protrusion. After the battery assembly is sealed, a gap is easily formed at the gate, which affects the seal between the sealing ring and the positive electrode shell and is detrimental to the battery's leakage resistance. Therefore, we need to propose a zinc-air button cell battery sealing ring injection mold. Utility Model Content

[0004] The purpose of this invention is to provide an injection mold for a zinc-air button cell sealing ring, which can quickly cool the first molding seat, the second molding seat, and the sealing ring to facilitate the unloading of the sealing ring, thereby improving the convenience of unloading the sealing ring and indirectly improving the production efficiency of the sealing ring, thus solving the problems mentioned in the background art.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] A zinc-air button battery sealing ring injection mold includes a fixed base 1 and a lifting base 2. A fixed frame 13 is fixedly installed inside the fixed base 1. Multiple sets of connecting rods 14 are fixedly installed at the bottom of the fixed frame 13. Each set of connecting rods 14 is fixedly installed with a shield 17.

[0028] The fixed base 1 has multiple sets of mounting bases 3 corresponding to the connecting rod 14. The top of the mounting base 3 is fixedly installed with a first forming base 6 corresponding to the shield 17. The mounting base 3 is provided with a lifting mechanism. The lifting mechanism is provided with a second forming base 7. The second forming base 7 is located on top of the first forming base 6. The mounting base 3 is provided with a cooling mechanism. The cooling mechanism is connected to the first forming base 6 and the second forming base 7.

[0029] In an optional embodiment: an injection seat 15 is fixedly installed on the connecting rod 14, the lower end of the injection seat 15 is inserted into the shield 17, the bottom of the injection seat 15 is flush with the bottom of the connecting rod 14, an injection hole 16 is provided on the injection seat 15, a molding cavity 19 is provided inside the shield 17, and the injection hole 16 communicates with the molding cavity 19.

[0030] It should be noted that by setting the shield 17, the sealing ring can be formed in the molding cavity 19 between the shield 17 and the first molding seat 6 and the second molding seat 7.

[0031] In an optional embodiment: the lifting mechanism includes a push rod 4, which is movably inserted into the fixed seat 1 and the mounting seat 3. The second molding seat 7 is fixedly installed on the top of the mounting seat 3, and the bottom of the second molding seat 7 contacts the top of the first molding seat 6.

[0032] It should be noted that by setting the push rod 4, the push rod 4 is lifted by the ejector device, so that the push rod 4 can cooperate with the second forming seat 7 to detach the formed sealing ring from the first forming seat 6, thereby facilitating the subsequent unloading of the sealing ring.

[0033] In an optional embodiment: both the first molding seat 6 and the second molding seat 7 are hollow inside. The cooling mechanism includes a conveying pipe 8, a connecting pipe 9, a first corrugated pipe 10, a drain pipe 11, a second corrugated pipe 12, a drain pipe 18, and a cooling water pipe 21. The drain pipe 18 and the cooling water pipe 21 are both fixedly installed inside the fixed seat 1. One end of the conveying pipe 8 is connected to the cooling water pipe 21, and the other end of the conveying pipe 8 is connected to the first molding seat 6. One end of the connecting pipe 9 is connected to the first molding seat 6, and the other end of the connecting pipe 9 is connected to the first corrugated pipe 10. The end of the first corrugated pipe 10 is connected to the bottom of the second molding seat 7.

[0034] It should be noted that the conveying pipe 8, connecting pipe 9, first corrugated pipe 10, drain pipe 11, second corrugated pipe 12, drain pipe 18 and cooling water pipe 21 work together to dissipate heat from the first forming seat 6, the second forming seat 7 and the sealing ring, thereby improving the cooling efficiency of the sealing ring and thus improving the production efficiency of the sealing ring.

[0035] In an optional embodiment: the drain pipe 11 is connected to the drain pipe 18, and a second corrugated pipe 12 is connected to the drain pipe 11. The end of the second corrugated pipe 12 is connected to the bottom of the second molding seat 7.

[0036] It should be noted that by cooperating with the first corrugated pipe 10 and the second corrugated pipe 12, the first corrugated pipe 10 and the second corrugated pipe 12 can extend and retract when the push rod 4 lifts the second forming seat 7, which can prevent the movement of the second forming seat 7 from being affected.

[0037] In an optional embodiment: a fixing rod 20 is fixedly installed inside the first molding seat 6, and a drain pipe 11 is fixedly installed on the fixing rod 20.

[0038] It should be noted that the fixing rod 20 can be used to install the drain pipe 11 and fix the drain pipe 11.

[0039] In an optional embodiment: the mounting base 3 is provided with a clearance groove 5, and the conveying pipe 8, the drain pipe 11 and the fixing rod 20 are all arranged in the clearance groove 5.

[0040] It should be noted that by setting the clearance groove 5, the push rod 4 can be prevented from contacting the conveying pipe 8, the connecting pipe 9, the drain pipe 11 and the fixed rod 20 when the push rod 4 is lifted, thus preventing the push rod 4 from affecting its movement.

[0041] In practical use, the lifting seat 2 is first pushed by the hydraulic lifting device (not shown in the figure) so that the lifting seat 2 is close to the fixed seat 1. The shield 17 can then cover the first molding seat 6 and the second molding seat 7. The injection molding liquid is injected into the molding cavity 19 through the injection hole 16, so that the injection molding liquid is injected and molded in the molding cavity 19. The lifting seat 2 is moved by the hydraulic lifting device so that the lifting seat 2 moves away from the first molding seat 6 and the second molding seat 7. The sealing ring after injection is attached to the first molding seat 6 and the second molding seat 7.

[0042] The water supply equipment (not shown in the figure) is started, and the coolant is transported through the cooling water pipe 21 to the conveying pipe 8. The coolant in the conveying pipe 8 enters the first forming seat 6, and after flowing through the first forming seat 6, it is transported through the connecting pipe 9 and the first corrugated pipe 10 to the second forming seat 7. After flowing through the second forming seat 7, it is discharged through the second corrugated pipe 12, the drain pipe 11 and the drain pipe 18. When the coolant enters the first forming seat 6 and the second forming seat 7, it carries away the heat of the first forming seat 6, the second forming seat 7 and the sealing ring, thereby quickly cooling the first forming seat 6, the second forming seat 7 and the sealing ring, so as to facilitate the unloading of the sealing ring and improve the convenience of unloading the sealing ring, thereby indirectly improving the production efficiency of the sealing ring. The push rod 4 is positioned by the ejector device (not shown in the figure), so that the push rod 4 pushes the sealing ring off the first forming seat 6 through the second forming seat 7, thereby facilitating the subsequent unloading of the sealing ring.

[0043] The hydraulic lifting equipment, water supply equipment, and ejection equipment described in this application are existing technologies and will not be explained in detail here. Furthermore, the control method for the hydraulic lifting equipment, water supply equipment, and ejection equipment is automatic control via a controller. The control circuit of the controller can be easily implemented by those skilled in the art through simple programming and is common knowledge in the field. Since this application primarily aims to protect the structure, shape, and their connections, the control method and circuit connections will not be explained in detail here.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
