Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to an automotive seat belt cover mold core exchange device. Background Technology

[0002] Seatbelt covers are an important component of automotive safety systems, primarily used to wrap the parts of the seatbelt webbing that come into contact with the human body, providing cushioning, wear resistance, and aesthetic appeal. With the automotive industry's increasing demands for parts production efficiency and flexible manufacturing, the core exchange device, as a key automated component in the automotive seatbelt cover mold production line, plays an increasingly important role. This device enables rapid replacement of cores of different specifications, meeting the production needs of diverse products, significantly improving the flexibility and efficiency of the production line, while reducing the time cost and operational risks of manual mold changes. It is a crucial link in the modern intelligent manufacturing system for automotive parts.

[0003] The traditional process of replacing automotive seatbelt cover mold cores relies on manual operation, which has significant drawbacks. On the one hand, manual mold replacement is time-consuming, requiring machine shutdown to disassemble the old mold core, install the new mold core, and perform repeated adjustments, resulting in low production line utilization and difficulty in adapting to the market demand for small batches and multiple varieties. On the other hand, the precision and stability of manual operation are insufficient, and installation errors can easily lead to mold core positioning deviations, affecting product dimensional accuracy and appearance quality, and even causing mold wear or production accidents. In addition, the traditional mold replacement method lacks an automated linkage mechanism and cannot be connected to the intelligent control system of the production line, making it difficult to achieve full-process digital monitoring and management, which restricts the development of automotive parts manufacturing towards high efficiency and intelligence. To address this, we propose an automotive seatbelt cover mold core exchange device. Utility Model Content

[0068] Paddle plate 24: Paddle plate 24 is fixed to the bottom of telescopic cylinder 23 and is used to grab and release mold core 8;

[0069] Working principle: When the mold core needs to be replaced, the mold-taking assembly starts first. The motor 16 drives the lead screw 17 to rotate through the output shaft. Since the lead screw 17 is threadedly connected to the threaded hole on the side of the slider 13, the rotation of the lead screw 17 will drive the slider 13 to move horizontally along the slide bar 14 and the slide groove 12. The direction of movement of the slider 13 is controlled by the direction of rotation of the motor 16, thereby achieving precise horizontal positioning. After the slider 13 moves directly above the mold core 8, the lifting structure starts to work. The telescopic cylinder 23 extends downward, driving the lever 24 to descend and insert into the slot or fixed part of the mold core 8. The lever 24 releases and grabs the mold core 8 from the production equipment 9 by mechanical clamping or levering. Subsequently, the telescopic cylinder 23 retracts, lifting the mold core 8 to a position detached from the production equipment 9. The coordinated movement of motor 16, lead screw 17, and slider 13 achieves horizontal positioning of the mold core. The cooperation of telescopic cylinder 23 and lever 24 completes the gripping and lifting of the mold core. The entire process requires no manual intervention, is highly efficient and precise. After the mold assembly grips the mold core 8, slider 13 moves along slide rod 14 towards support frame 2 under the drive of motor 16. At this time, the slide rail assembly begins to play its role. The transmission system composed of guide rail 18 and roller 19 provides stable support and low-friction guidance for the movement of mold core 8. The rotation of roller 19 reduces the resistance when mold core 8 moves, ensuring that it slides smoothly towards support frame 2. With the assistance of the slide rail assembly, mold core 8 is transported from the lower level of the production equipment 9 to the position of the mold core positioning structure. The horizontal movement of the slide rail assembly and the mold taking assembly... The synchronous operation ensures that the mold core does not shift or jam during transmission, improving transmission stability and efficiency. After the mold core 8 arrives at the mold core positioning structure, the U-shaped design of the mold core placement plate 20 provides initial positioning support. The mold core limiting plate 22 slides and adjusts via the sliding groove 21 to adapt to the width or length of the mold core 8 according to its specifications, thereby precisely fixing the mold core 8 in the preset position. The sliding of the mold core limiting plate 22 can be completed manually or automatically, ensuring that the mold core 8 does not shake or shift during the exchange process. The U-shaped structure of the mold core placement plate 20 not only plays a positioning role but also provides a stable foundation for the subsequent operation of the core replacement assembly. The mold core positioning structure achieves rapid adaptation to mold cores of different specifications through the adjustable mold core limiting plate 22. The fixed design avoids errors from manual adjustments and improves positioning accuracy. The core-changing assembly is the core of the device, responsible for removing the old mold core and feeding the new mold core into the production equipment 9. The core-changing guide rail 4 and roller 5 in the auxiliary structure provide auxiliary support for the movement of the mold core. The rotation of roller 5 further reduces the frictional resistance of the mold core movement. When the old mold core is placed into the mold core positioning structure, the limiting structure starts to work. The limiting block 7 slides to the preset position through the slide groove 3, locking the mold core 8 to prevent it from moving during the exchange process. The fixing rod 6 provides additional support for the limiting block 7 to ensure the reliability of the locking. The installation process of the new mold core is the reverse of the removal process of the old mold core. The core-changing guide rail 4 and roller 5 guide the new mold core to move to the designated position of the production equipment 9.The mold-taking assembly's lever 24 precisely places the mold core into the mold slot of the production equipment 9. The auxiliary and limiting structures of the core-changing assembly work together to ensure the mold core remains stable during the exchange process, avoiding installation errors caused by shaking or offset. After the new mold core is installed, the lever 24 of the mold-taking assembly resets, and the motor 16 drives the slider 13 back to its initial position, preparing for the next mold core exchange. Once the production equipment 9 detects that the mold core is in place, it automatically starts the production program to continue manufacturing the seatbelt sleeve.
