Technical Field
[0001] This utility model relates to the field of automotive terminal mold technology, specifically a mold for the production of assembled automotive terminals. Background Technology
[0002] Automotive terminal molds are specialized molds used for precision stamping of automotive wiring harness connection terminals. They are typically made of high-hardness alloy steel and are formed into terminal parts that meet electrical and mechanical performance requirements through processes such as bending. They are widely used in automotive battery connectors, sensor pins, signal terminals, and other scenarios to meet the stringent reliability and consistency requirements of automotive-grade wiring harnesses, and are widely used in practice.
[0003] Existing molds for automotive terminal production still have the following problems in actual use:
[0004] When using automotive terminal molds for production operations, only a single type of automotive connection terminal can be produced. It is not possible to produce multiple types of automotive connection terminals according to actual needs, which reduces operational efficiency. Furthermore, during bending, a certain impact force is generated, and the stability of the lower mold cannot be guaranteed simultaneously while pressing down. This reduces the accuracy of stamping and bending, thus lowering the actual production pass rate.
[0005] Therefore, this utility model introduces a mold for the production of assembled automotive terminals. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides an assembly-type automotive terminal production mold, which has the advantages of being able to adapt to the production of different types of automotive connection terminals and ensuring overall stability during stamping, thus solving the problems mentioned in the background art.
[0007] This utility model provides the following technical solution: a mold for producing assembled automotive terminals, comprising a mold base and a sliding plate. The upper surface of the mold base is provided with a pressing and stabilizing mechanism, which includes a fixed rack, a bidirectional screw, a connecting rod, a gear, and a threaded limiting plate. The upper surface of the fixed rack is fixedly installed with the lower surface of the sliding plate. A receiving seat is fixedly installed on the upper surface of the mold base. The outer surface of the bidirectional screw is rotatably connected to the inside of the receiving seat. One end of the connecting rod is fixedly installed with one end of the bidirectional screw. A gear is fixedly installed on the outer surface of the connecting rod. The outer surface of the bottom end of the threaded limiting plate is threadedly connected to the outer surface of the bidirectional screw.
[0008] Preferably, the sliding plate has a through groove inside, and a bottom plate is slidably connected inside the through groove. The right side of the bottom plate abuts against an upper mold, and the upper surface of the upper mold abuts against the lower surface of the sliding plate. A limit screw is threaded inside the bottom plate, and the outer surface of the limit screw is threaded with the inner surface of the upper mold.
[0009] Preferably, the receiving seat has a placement groove inside, and a U-shaped card seat is fixedly installed inside the placement groove.
[0010] Preferably, the U-shaped holder has a lower mold inside, and the back of the lower mold abuts against the front of the threaded limiting plate.
[0011] Preferably, the mold base has a receiving groove inside, and the size and shape of the receiving groove are the same as the size and shape of the fixed rack.
[0012] Preferably, guide rods are fixedly installed around the upper surface of the mold base, and a fixing plate is fixedly installed at one end of each guide rod.
[0013] Preferably, a hydraulic push rod is fixedly installed at the center of the upper surface of the fixed plate, and one end of the output shaft of the hydraulic push rod is fixedly connected to the upper surface of the sliding plate.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This type of assembled automotive terminal production mold, when the hydraulically driven sliding plate is pressed down, the fixed rack drives the gear, causing the bidirectional screw to rotate. This causes the threaded limit plate to move synchronously towards the center, achieving automatic centering and locking of the lower mold. This ensures the stability of the stamping process and avoids processing errors caused by mold misalignment. By adopting a U-shaped bracket and a replaceable lower mold mating structure, combined with the upper mold installation method that adjusts the limit screw, mold replacement is convenient and efficient, significantly shortening mold change time and improving production efficiency. This solves the problem of how to ensure more stable production of automotive connection terminals, avoiding the impact of impact forces on the production of automotive connection terminals, and ensuring the stability of the lower mold, thus improving the pass rate in actual production.
[0016] 2. This type of assembled automotive terminal production mold, through the sliding fit of the bottom plate in the through groove and the threaded connection structure of the limit screw, allows for the replacement of the upper mold. This ensures that different stamping types can be adapted to different operational uses in reality. The upper mold adopts a composite fixing method of abutment and threaded locking, which not only ensures stability during operation but also allows for quick disassembly by loosening the limit screw, achieving convenient replacement. This solves the problem of how to easily replace the upper mold, enabling the production of different types of automotive connection terminals according to actual needs. This improves operational efficiency in reality and facilitates the promotion and use of this mold in practice. Attached Figure Description

[0023] 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.
[0024] Please see Figure 3 and Figure 5A mold for producing assembled automotive terminals includes a mold base 1 and a sliding plate 6. A pressing and stabilizing mechanism is provided on the upper surface of the mold base 1. The pressing and stabilizing mechanism includes a fixed rack 11, a bidirectional screw 15, a connecting rod 16, a gear 17, and a threaded limiting plate 19. The upper surface of the fixed rack 11 is fixedly installed on the lower surface of the sliding plate 6. A receiving seat 5 is fixedly installed on the upper surface of the mold base 1. The outer surface of the bidirectional screw 15 is rotatably connected to the interior of the receiving seat 5. One end of the connecting rod 16 is connected to one end of the bidirectional screw 15. The connecting rod 16 is fixedly installed at the end. The outer surface of the connecting rod 16 is fixedly installed with a gear 17. The outer surface of the bottom end of the threaded limiting plate 19 is threadedly connected to the outer surface of the bidirectional screw 15. The receiving seat 5 has a placement groove 12 inside. A U-shaped card seat 13 is fixedly installed inside the placement groove 12. The lower mold 14 is engaged inside the U-shaped card seat 13. The back of the lower mold 14 abuts against the front of the threaded limiting plate 19. The mold base 1 has a receiving groove 18 inside. The size and shape of the receiving groove 18 are the same as the size and shape of the fixed rack 11.
[0025] Specifically, when the sliding plate 6 drives the fixed rack 11 to move, the fixed rack 11 can drive the gear 17 to rotate. The fixed rack 11 and the gear 17 adopt the same module design to ensure smooth transmission. In turn, it can drive the bidirectional screw 15 to rotate. When the bidirectional screw 15 rotates, the threaded limit plate 19 can move along the bidirectional screw 15, thereby limiting and fixing the lower mold 14 that is clamped in the U-shaped bracket 13, ensuring the stability of the lower mold 14 on the mold base 1, and improving the mold assembly accuracy and production quality. The combination of the size and shape of the receiving groove 18 and the fixed rack 11 provides moving space for the fixed rack 11, allowing the fixed rack 11 to move smoothly in the receiving groove 18, while ensuring the accurate relative position of the fixed rack 11 and the mold base 1.
[0026] Please see Figure 4 The sliding plate 6 has a through groove 7 inside, and a bottom plate 8 is slidably connected inside the through groove 7. The right side of the bottom plate 8 abuts against the upper mold 9. The upper surface of the upper mold 9 abuts against the lower surface of the sliding plate 6. The bottom plate 8 has a limit screw 10 connected to its internal thread, and the outer surface of the limit screw 10 is connected to the internal thread of the upper mold 9.
[0027] Specifically, the combination of the bottom plate 8 abutting against the upper mold 9 on its right side and the upper surface of the upper mold 9 abutting against the lower surface of the sliding plate 6 achieves the effect of initial positioning of the upper mold 9, ensuring a relatively stable position of the upper mold 9 under the sliding plate 6, facilitating subsequent fixing operations and ensuring the accuracy of the upper mold 9 installation. The combination of the limit screw 10 connected to the internal thread of the bottom plate 8 and the outer surface of the limit screw 10 connected to the internal thread of the upper mold 9 achieves the effect of firmly fixing the upper mold 9 to the bottom plate 8. This threaded connection method is not only convenient for installation and disassembly, but also ensures the connection strength between the upper mold 9 and the bottom plate 8, keeping the upper mold 9 stable during production and preventing loosening from affecting product quality.
[0028] Please see Figure 1 and Figure 2 Guide rods 2 are fixedly installed around the upper surface of the mold base 1. A fixing plate 3 is fixedly installed at one end of the guide rod 2. A hydraulic push rod 4 is fixedly installed at the center of the upper surface of the fixing plate 3. One end of the output shaft of the hydraulic push rod 4 is fixedly connected to the upper surface of the sliding plate 6.
[0029] Specifically, by fixing guide rods 2 around the upper surface of the mold base 1, a precise guide track is provided for the movement of the sliding plate 6, ensuring that the sliding plate 6 remains stable and vertical during up and down movement, and avoiding deviation or shaking. The combination of fixing hydraulic push rod 4 at the center of the upper surface of the fixed plate 3 and fixing one end of the output shaft of the hydraulic push rod 4 to the upper surface of the sliding plate 6 provides power to the sliding plate 6, enabling it to move up and down according to the set stroke and speed.
[0030] Working principle: During use, the assembled automotive terminal production mold drives the sliding plate 6 to press down along the guide rod 2 via the hydraulic push rod 4. The hydraulic push rod 4 mainly relies on the interaction of the high-pressure gas nitrogen and hydraulic oil inside it, achieving self-drive without external power input. This drives the fixed rack 11 to move synchronously, causing the gear 17 to rotate and the bidirectional screw 15 to rotate, thereby pushing the threaded limit plates 19 on both sides to move towards the center, achieving a stable clamping of the lower mold 14. At the same time, the upper mold 9 at the bottom of the sliding plate 6 cooperates with the lower mold 14 to complete the stamping of the terminal. The bottom plate 8 adjusts the installation of the upper mold 9 for different types through the limit screw 10, ensuring different stamping types and ensuring the consistency of terminal forming dimensions. During use, the lower mold 14 can be quickly replaced, and automatic centering and fixing are achieved through the linkage locking mechanism of the bidirectional screw 15. The upper mold 9 can also be replaced through the limit screw 10, improving production efficiency. It is suitable for precision stamping processing of automotive terminals of different specifications.
