Technical Field
[0001] This utility model relates to the field of data cable connector injection molding technology, and in particular to a data cable connector injection molding device with anti-bending protection. Background Technology
[0002] With the widespread use of smartphones and other portable mobile electronic devices, the demand for data cables, as essential accessories for charging and data transmission, has increased significantly. To meet market demand, efficient and high-quality data cable connector production technology is needed. Injection molding has become a common method for data cable connector production due to its advantages such as mass production capability and high molding precision.
[0003] In the conventional injection molding process of data cable connectors, the current common method is to insert the terminal into the corresponding interface of the positioning fixture for fixation. However, this method only focuses on the positioning of the terminal and ignores the effective fixation of the cable. Due to the lack of constraint on the cable, the cable is very prone to bending and displacement. Once the cable bends, it will not only cause the relative position between the cable and the terminal to shift, but also make the subsequent injection-molded connector and cable connection inaccurate, affecting the stability of data transmission and charging, thereby reducing the overall strength and durability of the data cable connector, and seriously affecting the injection molding effect and product quality.
[0004] To address this, a data cable connector injection molding device with bend-resistant protection is proposed. Utility Model Content
[0005] The purpose of this invention is to provide an injection molding device for data cable connectors with anti-bending protection. This device addresses the common practice in existing injection molding devices of fixing terminals by inserting them into the corresponding interfaces of positioning fixtures. However, this method only focuses on the positioning of the terminals and neglects the effective fixing of the cable. Due to the lack of constraint on the cable, it is prone to bending and displacement. Once the cable bends, its relative position to the terminal will shift, making the subsequent injection-molded connector and cable connection inaccurate, affecting the stability of data transmission and charging, thereby reducing the overall strength and durability of the data cable connector, and seriously affecting the injection molding effect and product quality.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a data cable connector injection molding device with anti-bending protection, comprising a support base, a lower mold bolted to the top of the support base, a positioning fixture provided inside the lower mold, a terminal provided inside the positioning fixture, and a cable provided on the side of the terminal away from the positioning fixture, an anti-bending mechanism provided on the front side of the support base, the anti-bending mechanism comprising a clamping component and a stretching component, the clamping component comprising a mounting block, a mounting groove provided on the top of the mounting block, the number of mounting grooves being multiple and evenly distributed, clamping plates provided on both sides inside the mounting groove, and the cable located between the opposite sides of the two clamping plates, telescopic rods fixedly connected to both sides of the inner wall of the mounting groove, and the side of the telescopic rods near the clamping plates being fixedly connected to the clamping plates, a fixing spring sleeved on the surface of the telescopic rods, and the two ends of the fixing springs being fixedly connected to the mounting groove and the clamping plates respectively;

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This application sets up a clamping component. The clamping plate in the mounting slot can form an elastic clamping structure through the telescopic rod and the fixed spring. It can automatically adjust the clamping force according to the thickness of the cable, thereby adapting to data cables of different specifications. It does not require frequent manual adjustment and is easy to operate. During the injection molding process, the clamping component can provide stable constraint for the cable, prevent it from bending or shifting due to external force, and ensure the accurate relative position of the cable and the terminal.

[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 Figures 1-5 The present invention provides the following technical solution:
[0025] A data cable connector injection molding device with anti-bending protection includes a support base 1, a lower mold 2 bolted to the top of the support base 1, a positioning fixture 3 disposed inside the lower mold 2, a terminal 4 disposed inside the positioning fixture 3, and a cable 5 disposed on the side of the terminal 4 away from the positioning fixture 3. An anti-bending mechanism 6 is disposed on the front side of the support base 1, the anti-bending mechanism 6 including a clamping component 61 and a stretching component 62. The clamping component 61 includes a mounting block 611, and a mounting groove 612 is formed on the top of the mounting block 611. The number of mounting slots 612 is set to multiple and evenly distributed. Both sides of the inside of the mounting slot 612 are provided with clamps 613 and the cable 5 is located between the opposite sides of the two clamps 613. Both sides of the inner wall of the mounting slot 612 are fixedly connected with telescopic rods 614, and the side of the telescopic rod 614 near the clamps 613 is fixedly connected to the clamps 613. A fixing spring 615 is sleeved on the surface of the telescopic rod 614, and the two ends of the fixing spring 615 are fixedly connected to the mounting slot 612 and the clamps 613 respectively.
[0026] In this embodiment: by setting up a clamping assembly 61, the mounting block 611 serves as the basic carrier of the clamping assembly 61, providing mounting positions for other components. Multiple mounting slots 612 can simultaneously accommodate multiple cables 5, meeting the needs of mass production of data cables and greatly improving the processing efficiency of the device. Clamping plates 613 are located on both sides inside the mounting slots 612. The two clamping plates 613 can directly contact and clamp the cables 5, ensuring that the cables 5 will not shift during the injection molding process. The telescopic rod 614 connects the inner wall of the mounting slot 612 and the clamping plates 613, serving to guide and restrict the movement direction of the clamping plates 613. The clamping mechanism ensures that the clamping plate 613 can only move closer or further away in the horizontal direction, making the clamping process more stable and precise. The fixing spring 615 is sleeved on the surface of the telescopic rod 614. When the cable 5 is placed between the clamping plates 613, the fixing spring 615 will be compressed and produce elastic deformation, thereby applying an inward elastic force to the clamping plate 613, so that the clamping plate 613 tightly clamps the cable 5. Furthermore, the elastic characteristics of the fixing spring 615 enable it to automatically adjust the clamping force according to the thickness of the cable 5. Whether the data cable is thin or thick, it can achieve stable clamping without manual adjustment, thus enhancing the device's adaptability to different specifications of cables 5.
[0027] Specifically, such as Figure 1 , Figure 5 As shown, the tensioning assembly 62 includes a screw 621, and grooves 7 are provided on both sides of the top of the support base 1. The screw 621 is rotatably connected to the inside of the left groove 7 through a bearing, and a guide rod 622 is fixedly connected to the inside of the right groove 7.
[0028] Specifically, such as Figure 5 As shown, a nut block 623 is threadedly connected to the surface of the screw 621, a guide block 624 is slidably connected to the surface of the guide rod 622, a connecting block 625 is fixedly connected to the top of the guide block 624 and the nut block 623, and the connecting block 625 is fixedly connected to the bottom of the mounting block 611.
[0029] Specifically, such as Figure 5 As shown, a drive motor 626 is fixedly connected to the front side of the support base 1, and the output shaft of the drive motor 626 is fixedly connected to the screw 621.
[0030] In this embodiment: By setting the tensioning assembly 62, the screw 621 is mounted in the left groove 7 of the support base 1 via a bearing and can rotate around the axis. When the drive motor 626 drives the screw 621 to rotate, the thread on its surface engages with the nut block 623, which can convert the rotational motion into linear motion, thereby pushing the nut block 623 to move axially along the screw 621. The guide rod 622 is fixed in the right groove 7 of the support base 1 and is arranged parallel to the screw 621. Its surface is smooth, and the guide block 624 can slide freely along the guide rod 622, thereby providing rigid guidance for the movement of the mounting block 611. To prevent the mounting block 611 from tilting or shaking during movement, the nut block 623 moves synchronously with the mounting plate via the connecting block 625, thereby enabling the stretching operation of the cable 5. The drive motor 626 provides power to the entire stretching assembly 62. The rotation direction of the screw 621 can be controlled by the forward and reverse rotation of the drive motor 626, thereby enabling the mounting block 611 to move back and forth, achieving the purpose of stretching or releasing the cable 5. This allows for precise adjustment of the tensile tension of the cable 5, adapting to the production needs of cables 5 of different specifications, and improving the automation and flexibility of the device.
[0031] Specifically, such as Figure 2 As shown, a top plate 8 is fixedly connected to the top of the support base 1, a cylinder 9 is fixedly connected to the top of the top plate 8, a mold base 10 is fixedly connected to the telescopic end of the cylinder 9, and an upper mold 11 is bolted to the bottom of the mold base 10, and the upper mold 11 is used in conjunction with the lower mold 2.
[0032] Specifically, such as Figure 2 As shown, a limiting rod 12 is fixedly connected to the top of the upper mold 11. The limiting rod 12 passes through the top plate 8 and is movably connected to the top plate 8.
[0033] In this embodiment: With the above settings, the top plate 8 is fixedly installed on the top of the support base 1, which can provide a stable installation platform for components such as the cylinder 9, ensuring the stability of subsequent component installation and operation. The cylinder 9 can drive the mold base 10 and the upper mold 11 to move up and down. During the injection molding process, the cylinder 9 can quickly and accurately control the mold closing and opening actions of the upper mold 11 and the lower mold 2. When closing the mold, it ensures that the upper mold 11 and the lower mold 2 fit tightly to form a complete injection cavity, ensuring the accuracy of injection molding. The mold base 10 acts as a bridge connecting the telescopic end of the cylinder 9 and the upper mold 11, allowing the cylinder 9 to... The power is stably transmitted to the upper mold 11 to ensure the safety and stability of the injection molding process. The upper mold 11 and the lower mold 2 together form the cavity for the injection molding of the data cable connector. After the mold is closed, its internal space shape is consistent with the design shape of the data cable connector. The molten plastic injected by the injection device 13 will cool and solidify in the cavity to form a data cable connector that meets the requirements. The limiting rod 12 can provide guidance for the movement of the upper mold 11, ensuring that the upper mold 11 can only move up and down in the vertical direction, avoiding horizontal deviation or shaking, and ensuring that the upper mold 11 and the lower mold 2 can be accurately closed.
[0034] Specifically, such as Figure 2 As shown, an injection device 13 is provided on the rear side of the support base 1, and the feeding end of the injection device 13 is fixedly connected to the lower mold 2.
[0035] Specifically, such as Figure 4 As shown, the two clamping plates 613 are provided with rubber material on opposite sides, and the bottom of the inner side of the clamping plate 613 is set as a slope.
[0036] In this embodiment: by setting up an injection device 13, the injection device 13 can heat and melt solid plastic particles into a fluid plastic melt. Pressure is generated through mechanisms such as a plunger, pushing the plastic melt towards the conveying end. When the molten plastic reaches the conveying end, under pressure, the plastic melt is precisely injected into the cavity formed after the upper mold 11 and lower mold 2 are closed, ensuring that the plastic uniformly fills the entire cavity, thereby guaranteeing the molding quality of the data cable connector. The two clamping plates 613 have opposite sides made of rubber. On one hand, rubber has a large coefficient of friction, which increases the friction between the clamping plates 613 and the cable 5, making the cable 5... The clamping mechanism is more stable when clamped, effectively preventing the cable 5 from sliding or shifting due to external forces during injection molding, ensuring the relative positional accuracy of the cable 5 and the terminal 4. On the other hand, the rubber is soft and has good elasticity, which can avoid damaging the outer sheath of the cable 5 when clamping it, protecting the integrity of the cable 5. The bottom inner side of the clamping plate 613 is set as a slope. This design makes it easier and faster to put the cable 5 into the clamping plate 613. When the cable 5 comes into contact with the slope, the slope will guide the cable 5 to slide naturally into the clamping area of the clamping plate 613, reducing the difficulty of placing the cable 5, reducing the workload of the operator, and improving the feeding efficiency.
[0037] Working principle: First, the terminal 4 is placed into the corresponding interface of the positioning fixture 3 in the lower mold 2 for fixation. Then, the cable 5 is placed in the mounting groove 612 on the top of the mounting block 611 of the clamping assembly 61. When the cable 5 slides into the mounting groove 612, it can quickly fall between the two clamping plates 613 using the inclined surface on the bottom inner side of the clamping plate 613. The clamping plate 613 will automatically clamp the cable 5 under the action of the fixing spring 615. Then, the drive motor 626 is started, which drives the screw 621 to rotate. The nut block 623 on the surface of the screw 621 will move linearly due to the thread transmission. At the same time, the guide block 624 on the surface of the guide rod 622 slides synchronously. The two drive the mounting block 611 to move through the connecting block 625, applying tensile force to the cable 5. According to the specifications of the cable 5, the cable 5 is adjusted... The speed and rotation angle of the drive motor 626 are precisely controlled to adjust the tension of the cable 5 to a suitable level, straighten the cable 5 and keep it stable. Then, the cylinder 9 is started. The telescopic end of the cylinder 9 pushes the mold base 10 and the upper mold 11 bolted to the bottom to move downward until the upper mold 11 and the lower mold 2 are precisely fitted to form a complete injection cavity. Finally, the injection device 13 heats and melts the solid plastic particles, and generates pressure through the internal plunger and other mechanisms to inject the plastic melt from the feeding end into the lower mold 2, filling the cavity formed by the mold of the upper mold 11 and the lower mold 2. After the injection is completed, wait for the plastic melt in the cavity to cool and solidify. Then, the cylinder 9 retracts, driving the upper mold 11 to move upward and open the mold. The operator can then take out the formed data cable connector and enter the next production cycle.
[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
