Description

Technical Field

[0001] This utility model relates to the field of automotive seat back panel covering technology, specifically an automotive seat back panel hot-press covering tooling. Background Technology

[0002] A hot-pressing fixture for automotive seat back panels is a specialized device used in the hot-pressing process of automotive seat back panels. This fixture typically comprises multiple components to ensure the accuracy and efficiency of the hot-pressing process. Using this fixture can significantly improve production efficiency and reduce errors caused by manual operation. Furthermore, due to its high flexibility and versatility, it can adapt to the production needs of various models and specifications of automotive seat back panels. The hot-pressing fixture is an indispensable piece of equipment in the automotive manufacturing process; its precise positioning capabilities, flexible rotation and lifting functions, and high versatility enable it to play a crucial role in the production of automotive seat back panels.

[0003] In most existing automotive seat back panels, the processing involves applying a leather back panel. The current method involves placing a cut rectangular piece of leather on a workbench, then placing the back panel on the leather, applying glue to the other side of the back panel, and manually pressing the four sides of the leather over the glue. However, manual wrapping is inefficient, and traditional manual wrapping is time-consuming, making it difficult to guarantee the consistency and tolerance of the wrapping. Using a tooling-equipped machine can shorten the wrapping cycle and improve consistency. Therefore, an automatic hot-pressing tooling for wrapping seat back panels has been developed. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a hot-press wrapping tool for automotive seat back panels to solve the technical problems of low efficiency in manual wrapping and bonding, long cycle time in traditional manual wrapping, and difficulty in ensuring wrapping consistency and tolerance range.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot-pressing wrapping fixture for an automotive seat back panel, comprising a mounting base and a frame body. A heating mold mechanism is provided at the top of the mounting base. The heating mold mechanism includes an upper mold, a lower mold, a material needle, a start switch, and a vacuum adsorption hole. A lower mold is provided at the top of the mounting base, and an upper mold is provided at the top of the lower mold. A heating mechanism is fixedly connected to the top of the frame body. The heating mechanism includes an upper mold heating platform, a lower mold heating platform, a movable heating frame, a first limiting mechanism, and a second limiting mechanism.

[0006] By adopting the above technical solution, the chair back panel plastic part is placed into the upper mold and positioned by the main positioning and the outer contour of the mold, and then fixed by the suction cup. At the same time, the chair back panel skin is placed into the lower mold. The lower mold material pins are positioned at the four corners and the heating table is turned on to activate the adhesive, so that the upper mold moves down to close the mold. This achieves hot pressing and wrapping of the chair back panel plastic part and the skin, thereby improving production efficiency and product yield.

[0007] Furthermore, a movable heating frame is provided at the top of the main frame, a lower mold heating platform is fixedly connected inside the movable heating frame, an upper mold heating platform is movably connected to the top of the lower mold heating platform, a first limiting mechanism that cooperates with the movable heating frame is fixedly connected to the outer wall of the lower mold heating platform, and a second limiting mechanism that cooperates with the first limiting mechanism is fixedly connected to the top of the movable heating frame.

[0008] By adopting the above technical solution, the heating mechanism is controlled by starting the switch. At this time, the upper mold heating platform and the lower mold heating platform move by moving the heating frame and then move to the side of the second limiting mechanism. When the second limiting mechanism receives a signal, the upper mold heating platform and the lower mold heating platform start the heating mode.

[0009] Furthermore, the lower mold is provided with multiple sets of material needles, the upper mold is provided with multiple sets of suction cups, the lower mold is provided with multiple sets of vacuum adsorption holes, and a frame body is fixedly connected between the mounting base and the lower mold.

[0010] By adopting the above technical solution, the user places the plastic part of the chair back panel into the upper mold, and positions it according to the main positioning and the outer contour of the mold, while fixing it with a suction cup. At the same time, the surface of the chair back panel is placed into the lower mold and positioned by the four corners of the material needle.

[0011] Furthermore, a start switch is provided between the mounting base and the lower mold, and both the start switch and the movable heating frame are electrically connected to an external power source.

[0012] By adopting the above technical solution, both the start switch and the movable heating frame are electrically connected to an external power source, thereby achieving the function of electrically controlling the whole system.

[0013] Furthermore, the upper mold contains a chair back panel plastic component, and the lower mold contains a chair back panel skin.

[0014] By adopting the above technical solution, through the structure of the upper mold containing the chair back panel plastic part and the structure of the lower mold containing the chair back panel skin, the lower mold moves downward and closes, thereby allowing the chair back panel plastic part and the chair back panel skin to be heat-pressed together.

[0015] In summary, this utility model has the following beneficial effects: By placing the plastic part of the chair back panel into the upper mold, and simultaneously positioning it using the main positioning and the outer contour of the mold, and then fixing it with a suction cup, the chair back panel skin is placed into the lower mold. The lower mold material pins are positioned at the four corners, and the heating table is turned on to activate the adhesive, so that the upper mold moves down to close the mold. This achieves hot-pressing and wrapping of the plastic part of the chair back panel and the skin, thereby improving production efficiency and product yield, and reducing production costs.

[0026] A tooling for hot-pressing and wrapping automotive seat back panels, such as Figure 1-7As shown, the device includes a mounting base 1 and a frame body 2. A heating mold mechanism 3 is mounted on the top of the mounting base 1. The heating mold mechanism 3 includes an upper mold 301, a lower mold 302, a material needle 303, a start switch 304, and a vacuum suction hole 305. The lower mold 302 is mounted on the top of the mounting base 1, and the upper mold 301 is mounted on the top of the lower mold 302. A heating mechanism 4 is fixedly connected to the top of the frame body 2. The heating mechanism 4 includes an upper mold heating platform 401, a lower mold heating platform 402, a movable heating frame 403, and a first limiting mechanism 404. The second limiting mechanism 405 involves placing the chair back panel plastic part 5 into the upper mold 301, simultaneously positioning it using the main positioning and mold outer contour, and then fixing it with a suction cup. At the same time, the chair back panel skin 6 is placed into the lower mold 302. The lower mold 302 is positioned by the four corners of the material needles 303, and the heating table is turned on to activate the adhesive, so that the upper mold 301 moves down to close the mold. This achieves hot-pressing of the chair back panel plastic part 5 and the chair back panel skin 6, thereby improving production efficiency and product yield, and reducing production costs.

[0027] Please see Figure 2 , Figure 3 and Figure 4 The frame body 2 has a movable heating frame 403 at its top. A lower mold heating platform 402 is fixedly connected inside the movable heating frame 403. An upper mold heating platform 401 is movably connected to the top of the lower mold heating platform 402. A first limiting mechanism 404 that cooperates with the movable heating frame 403 is fixedly connected to the outer wall of the lower mold heating platform 401. A second limiting mechanism 405 that cooperates with the first limiting mechanism 404 is fixedly connected to the top of the movable heating frame 403. The heating mechanism 4 is controlled by a start switch 304. At this time, the upper mold heating platform 401 and the lower mold heating platform 402 move through the movable heating frame 403 and then move to the side of the second limiting mechanism 405. When the second limiting mechanism 405 receives a signal, the upper mold heating platform 401 and the lower mold heating platform 402 start the heating mode.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 The lower mold 302 is equipped with multiple sets of material needles 303, the upper mold 301 is equipped with multiple sets of suction cups, and the lower mold 302 is equipped with multiple sets of vacuum adsorption holes 305.

At the same time, it is fixed by suction cups. Meanwhile, the chair back skin is put into the lower mold 302 and positioned by the four corners of the material needles 303.

[0029] The working principle of this utility model is as follows: When in use, the power is turned on, and the user separates and opens the upper mold heating table 401 and the lower mold heating table 402. Then the user puts the chair back plastic part 5 into the upper mold 301 and positions it according to the main positioning and the outer contour of the mold. At the same time, it is fixed by suction cup. Meanwhile, the chair back skin is put into the lower mold 302 and positioned by the four corners of the material needle 303.

[0030] During use, when the user controls the heating mechanism 4 by starting the switch 304, the upper mold heating platform 401 and the lower mold heating platform 402 move by moving the heating frame 403 and then move to the side of the second limiting mechanism 405. When the second limiting mechanism 405 receives a signal, the upper mold heating platform 401 and the lower mold heating platform 402 start the heating mode.

[0031] During use, after baking is completed, the moving heating mechanism 403 receives a signal, and the upper mold heating platform 401 and the lower mold heating platform 402 move to the first limiting mechanism 404 through the moving heating frame 403. When the first limiting mechanism 404 receives a signal, the lower mold 301 moves downward and closes the mold, thereby allowing the chair back plastic part 5 to be hot-pressed and wrapped with the chair back surface 6.
