Description
Technical Field
[0001] This utility model belongs to the field of stamping forming machine technology, specifically a guide mold structure for a micro connector precision stamping forming machine. Background Technology
[0002] The guide die of a precision stamping machine for micro-connectors is the core structure ensuring accurate die positioning and stable movement. Through the cooperation of high-precision guide pillars and guide sleeves, vertical alignment of the upper and lower dies is achieved within a micrometer range, preventing offset or tilting during the stamping process. Its design must balance high rigidity, wear resistance, and dustproof performance, typically using hardened alloy steel and integrating automatic lubrication and buffering devices. This technology is widely used in the manufacturing of micro-connectors (such as FPC terminals and SIM card trays), meeting the high-precision requirements of pitches below 0.3mm, while also being suitable for high-frequency stamping production. It is a key supporting technology for precision component processing in fields such as 5G communications and consumer electronics. The guide structure of existing micro connector precision stamping machines is inconvenient to replace when worn, which increases the difficulty of disassembly and assembly for operators and reduces work efficiency. Utility Model Content
[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides a guide mold structure for a precision stamping forming machine for micro connectors, which effectively solves the problem that the guide structure of the existing precision stamping forming machine for micro connectors is inconvenient to replace when worn, which increases the difficulty of disassembly and assembly for operators and reduces work efficiency.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a guide mold structure for a precision stamping forming machine for micro connectors, comprising a worktable, with support legs fixedly installed at both ends of both sides of the worktable, a lower mold fixedly installed at the center of the top of the worktable, a support frame fixedly installed on one side of the top of the worktable, a hydraulic cylinder fixedly installed on the top of the support frame, an upper mold fixedly installed at the transmission end of the hydraulic cylinder, upper slots being provided on both sides of the top of the upper mold, upper insert blocks being inserted into the upper slots, and guide sleeves being fixedly installed on the tops of the two upper insert blocks via support arms, with the interiors of the two guide sleeves being movable. The worktable is equipped with guide rods and two lower slots on both sides of the top. Lower blocks are inserted into the two lower slots. The tops of the two lower blocks are fixedly connected to the bottoms of the two guide rods. Lower locking rods are engaged inside the two lower blocks. Upper locking rods are engaged inside the two upper blocks. A connecting frame is slidably installed on one side of the support frame. A drive motor is fixedly installed on one side of the connecting frame. A transmission component is provided at the output end of the drive motor. The transmission component is connected to the two upper locking rods and the two lower locking rods. When the drive motor is running, it outputs power to the two upper locking rods and the two lower locking rods through the transmission component.
[0005] Preferably, the transmission assembly includes a threaded rod, which is fixedly installed at the output end of the drive motor. One end of the threaded rod is rotatably connected to the support frame. A threaded sleeve is threadedly connected to the surface of the threaded rod. Connecting strips are fixedly installed on both sides of the threaded sleeve through the support rod. One side of each connecting strip is fixedly connected to two upper clamping rods.
[0006] Preferably, a slider is fixedly installed at the bottom of the threaded sleeve, and a groove is provided at the inner bottom of the connecting frame, with the slider slidably installed inside the groove.
[0007] Preferably, a slide rod is fixedly installed at one end of the lower side of each connecting bar, and a sliding sleeve is fitted on the lower end of the surface of each slide rod. The surfaces of the two sliding sleeves are fixedly connected to the two lower clamping rods respectively, and the surfaces of the two lower clamping rods are fitted with insert sleeves. The two insert sleeves are fixedly connected to the worktable.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the operator starts the hydraulic cylinder to drive the upper mold to move down. When the upper mold moves down, it will drive the connecting frame to move down through the two upper clamping rods, and drive the two sliding rods to move down along the inside of the two sliding sleeves. When the upper mold moves down, it will drive the two guide sleeves to slide along the surface of the two guide rods through the two support arms, so that the upper mold moves down accurately and stably to cooperate with the lower mold for stamping. When the two guide rods and two guide sleeves are worn, the operator drags the connecting frame by hand and starts the drive motor to run forward. When the drive motor runs forward, it drives the threaded rod to rotate. When the threaded rod rotates, it drives the threaded sleeve to move. When the threaded sleeve moves, it drives the slider to slide inside the slide groove, which increases the stability of the threaded sleeve when it moves. When the threaded sleeve moves, it drives the two connecting bars to move away from the support frame through the two support rods. When the two connecting bars move, they drive the two sliding sleeves to move through the two sliding rods. When the two sliding sleeves move, they drive the two lower locking rods to move outward along the inside of the insert sleeve. At the same time, when the two connecting bars move, they also drive the two upper locking rods to move outward, thereby releasing the limit on the lower insert block and the upper insert block. Then the guide sleeve and guide rod can be disassembled and replaced. When installing new guide sleeves and guide rods, the operator inserts the upper and lower insert blocks of the two support arms and the two guide rods into the upper and lower slots respectively. Then, the operator lifts the connecting frame by hand to move the two support rods upward, so that the two support rods move the two upper locking rods through the two connecting strips until they are aligned with the two upper insert blocks. Then, the drive motor is started to run in reverse. When the drive motor runs in reverse, it moves the two support rods towards the upper mold through the threaded sleeve, thereby causing the two upper locking rods and two lower locking rods to engage with the two upper insert blocks and two lower insert blocks respectively for limiting installation, thus quickly completing the replacement. This makes the guide structure of this micro connector precision stamping forming machine easy to replace when worn, thereby reducing the difficulty of disassembly and assembly for the operator and improving work efficiency.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0012] Depend on Figures 1 to 5As shown, this utility model includes a workbench 1, with support legs 2 fixedly installed at both ends of both sides of the workbench 1, a lower mold 3 fixedly installed at the middle of the top of the workbench 1, a support frame 4 fixedly installed on one side of the top of the workbench 1, a hydraulic cylinder 5 fixedly installed on the top of the support frame 4, an upper mold 6 fixedly installed at the transmission end of the hydraulic cylinder 5, upper slots 12 are opened on both sides of the top of the upper mold 6, upper insert blocks 13 are inserted into the upper slots 12, and guide sleeves 8 are fixedly installed on the top of the two upper insert blocks 13 through support arms 7, and guide rods 9 are movably inserted into the two guide sleeves 8. When in use, the operator starts the hydraulic cylinder 5 to drive the upper mold 6 to move down. When the upper mold 6 moves down, the two support arms 7 drive the two guide sleeves 8 to slide along the surface of the two guide rods 9, so that the upper mold 6 moves down accurately and stably to cooperate with the lower mold 3 for stamping. Both sides of the top of the workbench 1 are provided with lower slots 10, and lower insert blocks 11 are inserted into the interior of each of the two lower slots 10. The top of each of the two lower insert blocks 11 is fixedly connected to the bottom of each of the two guide rods 9. Each of the two lower insert blocks 11 is respectively engaged with a lower locking rod 14. Each of the two upper insert blocks 13 is respectively engaged with an upper locking rod 15. A connecting frame 16 is slidably installed on one side of the support frame 4. A drive motor 17 is fixedly installed on one side of the connecting frame 16. The output end of the drive motor 17 is provided with a transmission component. The transmission component is connected to the two upper locking rods 15 and the two lower locking rods 14. When the drive motor 17 is running, it outputs power to the two upper locking rods 15 and the two lower locking rods 14 through the transmission component.
[0013] When the two guide rods 9 and the two guide sleeves 8 are worn, the operator drags the connecting frame 16 by hand and starts the drive motor 17 to run forward. The drive motor 17 runs forward, which drives the transmission assembly to run forward. When the transmission assembly runs forward, the two lower locking rods 14 and the two upper locking rods 15 move outward, thereby releasing the limit on the lower insert block 11 and the upper insert block 13. Then the guide sleeves 8 and guide rods 9 can be removed and replaced. When installing the new guide sleeve 8 and guide rod 9, the operator inserts the upper insertion block 13 and lower insertion block 11 at the bottom of the two support arms 7 and the two guide rods 9 into the upper slot 12 and lower slot 10 respectively. Then, the operator lifts the connecting frame 16 by hand to move the two support rods 20 upward, so that the two support rods 20 move the two upper locking rods 15 through the two connecting strips 21 to align with the two upper insertion blocks 13. Then, the drive motor 17 is started to run in reverse, which drives the transmission component to run in reverse. When the transmission component runs in reverse, it drives the two upper locking rods 15 and the two lower locking rods 14 to engage with the two upper insertion blocks 13 and the two lower insertion blocks 11 respectively for limiting installation, thereby quickly completing the replacement. This makes the guide structure of this micro connector precision stamping forming machine easy to replace when worn, thereby reducing the difficulty of disassembly and assembly for the operator and improving work efficiency.
[0014] The transmission assembly includes a threaded rod 18, which is fixedly installed at the output end of the drive motor 17. One end of the threaded rod 18 is rotatably connected to the support frame 4. A threaded sleeve 19 is threadedly connected to the surface of the threaded rod 18. Connecting strips 21 are fixedly installed on both sides of the threaded sleeve 19 via support rods 20. One side of each connecting strip 21 is fixedly connected to two upper clamping rods 15. A slider 25 is fixedly installed at the bottom of the threaded sleeve 19. A groove 26 is opened in the inner bottom of the connecting frame 16, and the slider 25 is slidably installed inside the groove 26. A slide bar 22 is fixedly installed on one end of the lower side of the connecting bar 21. A slide sleeve 23 is fitted on the lower end of the surface of the slide bar 22. The surfaces of the two slide sleeves 23 are fixedly connected to the two lower clamping rods 14 respectively. A plug sleeve 24 is fitted on the surface of the two lower clamping rods 14. The two plug sleeves 24 are fixedly connected to the worktable 1. The operator manually drags the connecting frame 16 and starts the drive motor 17 to run forward. When the drive motor 17 runs forward, it drives the threaded rod 18 to rotate. When the threaded rod 18 rotates, it drives the threaded sleeve 19 to move. When the threaded sleeve 19 moves, it drives the slider 25 to slide inside the slide groove 26, which increases the stability of the threaded sleeve 19 when it moves. When the threaded sleeve 19 moves, it drives the two connecting bars 21 to move away from the support frame 4 through the two support rods 20. When the two connecting bars 21 move, they drive the two sliding sleeves 23 to move through the two sliding rods 22. When the two sliding sleeves 23 move, they drive the two lower locking rods 14 to move outward along the inside of the insert 24. When the two connecting bars 21 move, they also drive the two upper locking rods 15 to move outward, thereby releasing the limit on the lower insert 11 and the upper insert 13. Then the guide sleeve 8 and the guide rod 9 can be removed and replaced. The operator lifts the connecting frame 16 by hand, causing the two support rods 20 to move upward. The two support rods 20 then move the two upper locking rods 15 through the two connecting strips 21 until they are aligned with the two upper insert blocks 13. Then, the drive motor 17 is started to run in reverse. When the drive motor 17 runs in reverse, it drives the two support rods 20 to move closer to the upper mold 6 through the threaded sleeve 19. This causes the two upper locking rods 15 and the two lower locking rods 14 to respectively engage inside the two upper insert blocks 13 and the two lower insert blocks 11 for limiting installation, thereby quickly completing the replacement.
