It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0025] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence.

[0026] The terms "comprising" and "having" and any variations thereof in the description and claims of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0027] Such as Figure 1-7The hot pressing tooling for automotive trim panels shown includes a fixedly arranged frame 1. At the upper end of the frame 1, a pair of limiting frames 2 are fixedly connected. In fact, the frame 1 includes a base 101 at the bottom. A pair of brackets 102 are fixedly connected to the base 101. The two limiting frames 2 are respectively fixedly connected to the tops of the two brackets 102. And the two limiting frames 2 are symmetric front and back. Also, a rib plate 4 is fixedly connected between the bottom surface of the limiting frame 2 and the side surface of the bracket 102 to improve the connection strength between the limiting frame 2 and the bracket 102.

[0028] A pair of clamping frames 7 are movably connected between the two limiting frames 2. The two clamping frames 7 are symmetric left and right. The top of each clamping frame 7 is rotatably connected to the two limiting frames 2. Specifically: Each limiting frame 2 is provided with two sliding holes 201. The sliding holes 201 are circular waist rectangles. The clamping frame 7 includes an upper shaft body 720. Both ends of the upper shaft body 720 have coaxial end shafts 721. The two end shafts 721 of the upper shaft body 720 respectively cooperate with the corresponding sliding holes 201 of the two limiting frames 2 to form a rotating pair and a sliding pair. In this way, the distance between the two upper shaft bodies 720 can be adjusted adaptively, so as to adapt to automotive trim panels of different widths and provide hot pressing limitation and support for automotive trim panels of different models. After the end shaft 721 passes through the sliding hole 201, a limiting plate 722 is fixedly connected to prevent the upper shaft body 720 from moving back and forth.

[0029] A linkage plate 6 is rotatably connected to the bottom of the clamping frame 7. A number of swing arms 730 are also rotatably connected to the outside of the upper shaft body 720. The upper ends of the swing arms 730 are fixedly connected together with an embedded clamping plate 740 for engaging with the side protrusions of the automotive trim strip. The embedded clamping plate 740 is generally made of wear-resistant materials such as plastic or hard rubber, and friction grooves 741 are provided on its upper surface to increase the contact friction between the embedded clamping plate 740 and the automotive trim strip and further improve the clamping stability. The lower ends of the swing arms 730 are rotatably connected to the linkage plate 6 through lower shaft bodies 710. Each upper end of the swing arms 730 is provided with an upper shaft hole 732 for forming a rotating pair with the upper shaft body 720. Each lower end of the swing arms 730 is provided with a lower shaft hole 731. The lower shaft body 710 includes a smooth shaft 711 that just passes through all the lower shaft holes 731 on the same side, so that the swing arms 730 on the same side can better maintain parallelism. After the two ends of the smooth shaft 711 pass through the lower shaft holes 731, limiting rings 712 are fixedly connected to prevent the smooth shaft 711 from disengaging from any one of the swing arms 730. The upper shaft body 720 is located between the lower shaft body 710 and the embedded clamping plate 740, and the upper shaft body 720 is very close to the embedded clamping plate 740. The part of the swing arm 730 located below the upper shaft body 720 has a larger swing range.

[0030] Each linkage plate 6 is inclined, and its upper end is located between two clamping brackets 7. The upper ends of the symmetrically arranged linkage plates 6 on the left and right are close to each other. The upper ends of all the clamping brackets 7 are jointly and rotatably connected to a horizontal traction plate 5. A lower hinge hole 601 is formed at the lower end of the linkage plate 6 for cooperating with the optical axis 711 to form a rotating pair. An upper hinge hole 602 is formed at the upper end of the linkage plate 6. A relief groove 501 is formed on the side surface of the traction plate 5. A force application shaft 502 is fixedly connected to the traction plate 5 within the relief groove 501, which exactly cooperates with the upper hinge hole 602 to form a rotating pair. In this embodiment, the number of swing arms 730 on the same side is three, and the number of linkage plates 6 on the same side is two, which can be alternately arranged at intervals.

[0031] A driver 3 is connected between the traction plate 5 and the frame 1. The driver 3 adopts a cylinder with a simple structure, rapid response and low use cost. The bottom of the cylinder barrel of the driver 3 is fixedly connected to the base 101, and the movable end of the driver 3 is connected to the traction plate 5 for driving the traction plate 5 to move up and down relative to the frame 1, so as to change the relative angle and distance between the two clamping brackets 7 to complete the actions of clamping and releasing the automotive trim panel.

[0032] Working principle: Before placing the automotive trim panel, the driver 3 contracts. The descending traction plate 5 will make the lower ends of the clamping brackets 7 move away from each other through the linkage plates 6. At the same time, the opposite sides of the embedded clamping plates 740 tilt upward and slightly approach each other. Place the automotive trim panel to be hot-pressed on the two embedded clamping plates 740, and then the driver 3 can extend. The opposite sides of the two embedded clamping plates 740 gradually flatten and move away from each other until they are clamped inside the flange on the inner surface of the automotive trim panel. At this time, the automotive trim panel is clamped on the tooling, and other structures can be hot-pressed on the trim panel; after the hot pressing is completed, the clamping brackets 7 contract again, and the hot-pressed automotive trim parts can be easily removed from the tooling, and then the next round of hot pressing operation can be repeated.

[0033] The above describes the basic principle, main features and advantages of the present application. Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed. The scope of protection required by the present application is defined by the appended claims and their equivalents.
