Description

Technical Field

[0001] This utility model belongs to the field of connector manufacturing technology, specifically relating to a high-precision stamping die for connectors. Background Technology

[0002] With the rapid development of the electronics manufacturing industry, connectors, as an important component of electronic parts, have become crucial in terms of precision and quality control during their manufacturing process. High-precision stamping dies play a key role in connector production, directly affecting the connector's dimensional accuracy, shape consistency, and overall performance. Traditional stamping dies often suffer from insufficient precision, easy wear, and complex operation. These problems not only affect production efficiency but may also impact product quality, thereby affecting the end-user experience.

[0003] Traditional stamping dies, when used for connector fastening, may experience a decrease in precision over prolonged use due to wear and vibration, failing to meet the production requirements of high-precision connectors. The impact and friction generated during stamping easily lead to die wear, shortening die life and increasing maintenance and replacement costs. Traditional dies have complex structures, lack flexibility in adjusting stamping depth, and are difficult to adapt to the production needs of connectors of different specifications. Installation and maintenance require considerable time and are prone to errors during operation. Insufficient stability of the die during high-speed movement may lead to safety accidents such as disengagement, posing a threat to operators and equipment.

[0004] In view of this, a high-precision stamping die design for connectors is proposed to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problems of insufficient precision, easy wear and complicated operation of stamping dies in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A high-precision stamping die for connectors includes a snap-fit ​​die, a guide block, and a guide frame;

[0008] The snap-fit ​​die presses and flattens both sides of the connector during the connector stamping and snap-fit ​​process;

[0009] The guide block is used to fix the snap-fit ​​mold and align with the push block on the upper stamping mold. When the push block moves down and aligns with the guide block, the guide block pushes the snap-fit ​​mold towards the connector and presses and flattens both sides of the connector.

[0010] The guide frame works with the guide block and the snap-fit ​​mold to slide and guide. The guide frame is equipped with a horizontal guide rod that works with the guide block to guide the sliding motion and prevents jump-out.

[0011] When the guide block moves along the guide frame, the two outer cylinders at the front end of the guide block cooperate with the two inner cylinders on the guide frame to slide. Two springs are fixed between the guide block and the guide frame and are sleeved on the outside of the outer and inner cylinders.

[0012] Preferably, the guide frame includes a U-shaped block and a convex block that is threadedly connected to the U-shaped block by bolts, and a horizontal guide rod is disposed between the U-shaped block and the convex block.

[0013] Preferably, the U-shaped block has a buffer groove that cooperates with the guide block and the guide movement of the locking die. The buffer groove can absorb and disperse the impact force generated during the stamping process, protecting the die from damage.

[0014] Preferably, the U-shaped block has operating openings at both the front and rear ends on its left and right sides, and mounting holes are provided on the U-shaped block within the operating openings to position the guide frame. The operating openings facilitate the installation and operation of the guide frame, improving work efficiency. The mounting holes ensure the accurate installation position of the guide frame in the mold, improving stamping precision.

[0015] Preferably, the guide block has a beveled surface A on its rear side, and the push block has a beveled surface B at its bottom that aligns with the beveled surface A to form a right-angle block.

[0016] Preferably, the guide block has a straight slot at its front end, which connects to a rectangular groove below. The locking mold is fixed to the guide block by a screw and a locking nut that pass through the straight slot, with the locking nut hidden inside the rectangular groove. The design of the straight slot and the rectangular groove allows for fine-tuning of the locking mold's position relative to the guide block.

[0017] Preferably, the convex block is threaded with a limiting rod that engages with the push block for positioning. The limiting rod restricts the range of motion of the push block, prevents overshoot, and protects the mold and connector from damage.

[0018] Preferably, the top of the convex block is fixed with an upper mold cover plate by screws, and the upper mold cover plate has a U-shaped opening for exposing the U-shaped block, guide block and snap-fit ​​mold.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are:

[0020] This connector's high-precision stamping die, through the combined use of guide blocks and guide frames, as well as the buffering effect of springs, reduces die displacement and vibration, thereby improving stamping accuracy and die stability.

[0021] The design of the buffer groove reduces the impact force on the mold, while the spring between the guide block and the guide frame buffers the impact and reduces wear. The design of the operating port and mounting hole simplifies the mold installation and maintenance process and improves work efficiency; the design of the horizontal guide rod prevents the guide block from jumping off during high-speed movement and enhances the safety of the mold.

[0022] The beveled surface design and the application of the limiting rod allow the die to be easily adjusted in terms of stamping depth, adapting to the production needs of connectors of different specifications.

[0023] In summary, the proposed high-precision stamping die design has significant advantages in improving production efficiency, ensuring product quality, reducing production costs, and extending die life. It can effectively solve the defects of existing technologies and meet the needs of the electronics manufacturing industry for high-precision connector production. Attached Figure Description

[0030] 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.

[0031] The following is combined with Figure 1-5This application will be described in further detail.

[0032] This application discloses a high-precision stamping die for a connector, including a snap-fit ​​die 1, a guide block 2, and a guide frame 4;

[0033] During the connector stamping and fastening process, the fastening die 1 presses and flattens both sides of the connector.

[0034] The guide block 2 is used to fix the snap-fit ​​mold 1 and align with the push block 3 on the upper stamping mold. When the push block 3 moves down and aligns with the guide block 2, the guide block 2 pushes the snap-fit ​​mold 1 toward the connector and presses and flattens the two sides of the connector.

[0035] The guide block 2 has a beveled surface A21 on its rear side, and the push block 3 has a beveled surface B31 at its bottom that aligns with the beveled surface A21 to form a right-angle block. The beveled surface design allows the guide block 2 and push block 3 to smoothly connect, forming a stable right-angle structure and reducing impact and friction. The aligned beveled surface design also reduces wear on the contact surfaces.

[0036] The guide block 2 has a straight slot 22 at its front end, which connects to a rectangular groove 23 at its lower end. The locking mold 1 is fixed to the guide block 2 by a screw 11 and a locking nut 12 passing through the straight slot 22. The locking nut 12 is hidden within the rectangular groove 23. The straight slot 22 and the rectangular groove 23 allow the locking mold 1 to be firmly fixed to the guide block 2 by the screw 11 and the locking nut 12, improving the stability of the overall structure. The locking nut 12 being hidden within the rectangular groove 23 reduces visual disharmony and protects the nut from damage. In addition, the design of the straight slot 22 and the rectangular groove 23 allows for fine adjustment of the position of the locking mold 1 relative to the guide block 2.

[0037] The guide frame 4 is slidably guided by the guide block 2 and the snap-on mold 1. The guide frame 4 is provided with a horizontal guide rod 5 that is slidably guided by the guide block 2 and prevents jump-out.

[0038] The guide frame 4 includes a U-shaped block 41 and a U-shaped block 42 that is threadedly connected to the U-shaped block 41 by bolts. A horizontal guide rod 5 is located between the U-shaped block 41 and the U-shaped block 42. This provides additional support and stability, reducing vibration and displacement during the stamping process. The U-shaped block 41 has a buffer groove 43 that guides the movement of the guide block 2 and the snap-fit ​​die 1. The buffer groove 43 absorbs and disperses the impact force generated during stamping, protecting the die from damage. The buffer groove 43 also facilitates the smooth guiding movement of the guide block 2 and the snap-fit ​​die 1, reducing wear.

[0039] Operating ports 44 are provided at the front and rear ends of both sides of the U-shaped block 41. Mounting holes 45 are provided on the U-shaped block 41 within the operating ports 44 to position and install the guide frame 4. The operating ports 44 make the installation and operation of the guide frame 4 more convenient, improving work efficiency. The mounting holes 45 ensure the accurate installation position of the guide frame 4 in the mold, improving stamping accuracy.

[0040] The U-shaped block 42 is threadedly connected to a limiting rod 46 that engages with the push block 3 for positioning. The limiting rod 46 restricts the movement range of the push block 3, preventing over-stroke and protecting the mold and connector from damage. The length of the limiting rod 46 can be easily adjusted via the threaded connection to accommodate different stamping depth requirements.

[0041] The top of the U-shaped block 42 is fixed with an upper mold cover plate 9 by screws. The upper mold cover plate 9 has a U-shaped opening 91 that exposes the U-shaped block 41, guide block 2, and snap-fit ​​mold 1. The upper mold cover plate 9 can protect the internal structure from external contamination and damage. The U-shaped opening 91 makes the guide block 2, snap-fit ​​mold 1, and other components visible, which is convenient for operators to monitor and adjust the mold status.

[0042] When the guide block 2 moves along the guide frame 4, the two outer cylinders 6 at the front end of the guide block 2 cooperate with the two inner cylinders 7 on the guide frame 4 to guide and slide. Two springs 8 are fixedly provided between the guide block 2 and the guide frame 4, which are sleeved on the outside of the outer cylinders 6 and the inner cylinders 7.

[0043] This high-precision stamping die for the connector uses a snap-fit ​​die 1 to press and flatten both sides of the connector during the stamping process, helping to ensure that the dimensions and shape of both sides of the connector meet the precision requirements, thereby improving the overall accuracy of the product. The cooperation between guide block 2 and guide frame 4 provides stable guidance, ensuring the accurate movement trajectory of the die throughout the stamping process and reducing errors caused by die displacement or vibration. The alignment and splicing of guide block 2 with push block 3 on the upper stamping die allows snap-fit ​​die 1 to move quickly and accurately to the connector position during the stamping process, improving production efficiency. The spring 8 fixed between guide block 2 and guide frame 4 buffers the impact force during the stamping process, reducing direct collisions between dies, thereby reducing wear and extending the die's service life. The design of the horizontal guide rod 5 helps prevent guide block 2 from jumping out during high-speed movement, ensuring the stability and safety of the die.

[0044] The two outer cylinders 6 at the front end of the guide block 2 cooperate with the two inner cylinders 7 on the guide frame 4 to guide and slide, thereby improving the stability and accuracy of the mold, and producing connector products with higher consistency and reliability, which is conducive to improving product quality and user satisfaction.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
