Description

A connector terminal stamping anti-deformation die with guide buffer Technical Field

[0001] This utility model relates to the field of connector terminals, and more specifically, to a stamping mold for connector terminals with guide buffer to prevent deformation. Background Technology

[0002] Connectors are key components for achieving electrical connections, and their performance and quality directly affect the stability and reliability of the entire electronic system. Connector terminals, as the core components of connectors, bear the important function of current and signal transmission, and have extremely high requirements for their dimensional accuracy, structural integrity and surface quality. At present, stamping is the main production method for connector terminals. However, existing connector terminal stamping dies still have many technical problems that need to be solved in the actual production process, among which the problem of terminal stamping deformation is particularly prominent.

[0003] A search revealed an existing patent (publication number: CN216461365U) that discloses a stamping die for a new energy connector end piece, comprising a fixing mechanism and a protective mechanism. The fixing mechanism has guide mechanisms on both sides above it for preventing offset, and the protective mechanism for buffering protection is located in the upper center of the fixing mechanism. This new energy connector end piece stamping die, through a lifting column and a second spring, can extend and retract to buffer the upper die base during lifting, thereby protecting the processed object and preventing damage due to excessive pressure. A positioning rod can be used for positioning during mating, reducing deformation. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing connector terminal stamping anti-deformation dies use simple lifting columns to guide the upper die base, which has poor stability. This guiding method can only ensure the relative position of the upper and lower die bases to a certain extent. During the stamping process, the lateral force on the die base cannot be effectively balanced and constrained, which can easily cause the upper die base to shift at the moment of stamping. This can lead to dimensional deviations and shape deformations in the stamped connector terminals. In addition, when replacing the punch, two bolts are required to lock it in place, which is cumbersome during replacement.

[0005] Therefore, a connector terminal stamping anti-deformation mold with guide buffer is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a connector terminal stamping anti-deformation mold with guide buffer to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a connector terminal stamping anti-deformation mold with guide buffer, comprising a lower mold base, an upper mold base above the lower mold base, an installation groove on the front of the upper mold base, an installation horizontal plate inside the installation groove, two punches fixedly connected to the bottom surface of the installation horizontal plate, a threaded opening on the upper surface of the upper mold base, a threaded groove on the upper surface of the installation horizontal plate, a fixing screw threaded to the inner wall of the threaded opening, two sets of guide holes on the upper surface of the upper mold base, two sets of guide rods fixedly connected to the upper surface of the lower mold base, the outer surfaces of the two sets of guide rods being slidably connected to the inner walls of the two sets of guide holes respectively, positioning seats fixedly connected to the left and right sides of the lower mold base, and two positioning blocks fixedly connected to the left and right sides of the upper mold base, with the outer surfaces of the positioning blocks matching the inner walls of the positioning seats.

[0008] Preferably, springs are fixedly connected to the inner bottom walls of both positioning seats, and buffer slides are fixedly connected to the top ends of both springs. The outer surfaces of the two buffer slides are slidably connected to the inner walls of the two positioning seats, and the buffer slides are located below the positioning blocks. Limiting openings are provided on the opposite sides of the two positioning seats, and the inner walls of the two limiting openings are slidably connected to the outer surfaces of one end of the two buffer slides.

[0009] Preferably, the outer surface of the lower mold base is provided with two sets of recessed holes, and the inner bottom wall of both sets of recessed holes is provided with mounting holes.

[0010] Preferably, the upper surface of the upper mold base is fixedly connected to two connectors, and the upper surface of the two connectors is provided with connection holes.

[0011] Preferably, the upper surface of the lower die base has two stamping grooves, and the two punches are respectively located above the two stamping grooves.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] Compared with existing technologies, this connector terminal stamping anti-deformation die with guide buffer can provide initial guidance for the upper and lower die bases through the cooperation of guide rod and guide hole. The structure of positioning block and positioning seat can further limit the lateral movement of the upper die base. In addition, with the buffering effect of buffer slide and spring, it can effectively balance and constrain the lateral force during stamping, avoid the upper die base from deflection, and reduce the occurrence of dimensional deviation and shape deformation of connector terminals at the stamping point.

[0014] Compared with existing technologies, this connector terminal stamping anti-deformation mold with guide buffer can drive the punch to be installed inside the upper mold base by the mounting groove set in the upper mold base. In addition, by the fixing screw passing through the threaded opening and threaded groove, the mounting plate can be fixed at the bottom of the upper mold base, thereby realizing the quick assembly and disassembly of the punch, simplifying the operation process and improving work efficiency.

[0020] 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.

[0021] As shown in Figures 1-4, a connector terminal stamping anti-deformation mold with guide buffer includes a lower mold base 1, an upper mold base 2 above the lower mold base 1, an installation groove 10 on the front of the upper mold base 2, an installation horizontal plate 12 inside the installation groove 10, two punches 11 fixedly connected to the bottom surface of the installation horizontal plate 12, a threaded opening 14 on the upper surface of the upper mold base 2, a threaded groove 13 on the upper surface of the installation horizontal plate 12, a fixing screw 15 threadedly connected to the inner wall of the threaded opening 14, two sets of guide holes 3 on the upper surface of the upper mold base 2, two sets of guide rods 4 fixedly connected to the upper surface of the lower mold base 1, the outer surfaces of the two sets of guide rods 4 are slidably connected to the inner walls of the two sets of guide holes 3 respectively, positioning seats 5 are fixedly connected to the left and right sides of the lower mold base 1, and two positioning blocks 8 are fixedly connected to the left and right sides of the upper mold base 2, and the outer surface of the positioning blocks 8 is adapted to the inner wall of the positioning seats 5.

[0022] As can be seen from the above description, the present invention has the following beneficial effects: the sliding cooperation between the guide hole 3 at the upper die base 2 and the guide rod 4 at the lower die base 1 provides basic guidance for the up and down movement of the upper die base 2, ensuring that the upper die base 2 moves smoothly in the vertical direction. In addition, the cooperation between the positioning seats 5 on both sides of the lower die base 1 and the positioning blocks 8 on both sides of the upper die base 2 allows the positioning blocks 8 to be inserted into the positioning seats 5 during the stamping process, playing a precise positioning role, restricting the lateral movement of the upper die base 2, effectively preventing the upper die base 2 from shifting during stamping, ensuring stamping accuracy, and preventing dimensional deviations and shape deformations of the connector terminals.

[0023] As shown in Figures 1-4, springs 7 are fixedly connected to the inner bottom walls of both positioning seats 5, and buffer slide plates 6 are fixedly connected to the top of both springs 7. The outer surfaces of the two buffer slide plates 6 are slidably connected to the inner walls of the two positioning seats 5, and the buffer slide plates 6 are located below the positioning block 8. Limiting ports 9 are opened on the opposite sides of the two positioning seats 5. The inner walls of the two limiting ports 9 are slidably connected to the outer surfaces of one end of the two buffer slide plates 6. Furthermore, by inserting the positioning block 8 into the positioning seat 5, the buffer slide plate 6 slides within the positioning seat 5 and compresses the springs 7. The elastic deformation of the springs 7 absorbs the impact force generated by stamping, playing a buffering and shock-absorbing role. In addition, the limiting ports 9 limit the sliding of the buffer slide plate 6, ensuring the stable sliding of the buffer slide plate 6, further improving the stability of the mold during the stamping process, reducing the impact of vibration on stamping accuracy, better protecting the mold and improving the forming quality of the connector terminals.

[0024] As shown in Figures 1-4, in a preferred embodiment, the outer surface of the lower die base 1 has two sets of recessed holes 18, and the inner bottom wall of each of the two sets of recessed holes 18 has mounting holes 19. The upper surface of the upper die base 2 is fixedly connected to two connectors 16, and the upper surface of each connector 16 has a connecting hole 17. The upper surface of the lower die base 1 has two stamping grooves 20, and two punches 11 are respectively located above the two stamping grooves 20. Furthermore, through the recessed holes 18 and mounting holes 19, the lower die base 1 can be easily fixed to the worktable of the stamping equipment by bolts or other connecting components, so as to achieve a stable connection between the die and the equipment. The connectors 16 and connecting holes 17 on the surface of the upper die base 2 are used to connect to the power mechanism of the stamping equipment, so that the upper die base 2 can move up and down under the drive of the equipment. Through the correspondence between the stamping grooves 20 and the positions of the punches 11, the punches 11 move down into the stamping grooves 20 during stamping, so as to stamp the connector terminal material placed on the lower die base 1, ensuring the smooth progress of the stamping process and the forming effect.

[0025] The working process of this utility model is as follows:

[0026] When the upper die 2 is pressed downwards, the guide hole 3 of the connector terminal stamping anti-deformation mold with guide buffer can slide downwards on the surface of the guide rod 4 during later use, providing initial guidance for the upper die 2 to close downwards. At the same time, the positioning blocks 8 on both sides of the upper die 2 are inserted into the interior of the positioning seat 5, further restricting the lateral movement of the upper die 2. When the positioning block 8 is inserted into the positioning seat 5, the buffer slide 6 can slide inside the positioning seat 5 when it is pressed by the positioning block 8. Then the spring 7 is compressed to play a buffering role, absorbing the impact force during the stamping process, further stabilizing the upper die 2, and preventing the mold from shaking due to the impact force.

[0027] When the punch 11 is installed or replaced, the mounting plate 12 is placed in the mounting groove 10 of the upper die base 2. The fixing screw 15 passes through the threaded opening 14 of the upper die base 2 and the threaded groove 13 of the mounting plate 12 in sequence, which can fix the mounting plate 12 to the upper die base 2 and make the punch 11 quickly fixed on the bottom surface of the mounting plate 12. This is the working process and working principle of the device.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
