[0001] This utility model relates to the field of automotive interior parts processing, specifically to a negative pressure absorption heating type leather layer shaping device for interior parts. Background Technology

[0002] When leather is manually applied to automotive interior parts, air bubbles and hollow areas can easily form because manual application cannot completely remove air between the leather and the substrate. Furthermore, uneven pressure applied manually makes it difficult to properly adhere to complex curved surfaces, affecting the overall quality of the leather layer on the interior parts.

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-3 A negative pressure suction heating type leather layer shaping device for interior parts includes a frame 1, a lateral clamping mechanism 2, a sensing mechanism 3, and a control mechanism 4. The frame 1 is provided with a support mold 11 for carrying the interior parts, and a heating plate 12 is provided on both sides of the support mold 11. The lateral clamping mechanism 2 is provided on the frame 1 and is used to clamp the interior parts from both sides of the support mold 11. In the working state, when the interior parts are installed on the support mold 11, the sensing mechanism 3 activates the lateral clamping mechanism 2 through the control mechanism 4, and the lateral clamping mechanism 2 clamps the interior parts.

[0027] This invention achieves the function of automatically clamping interior trim parts after installation through a frame 1, a lateral clamping mechanism 2, a sensing mechanism 3, and a control mechanism 4. Simultaneously, the cooperation of the sensing mechanism 3 and the control mechanism 4 ensures the installation status of the interior trim parts, solving the problem of inaccurate feeding affecting the shaping quality of traditional shaping devices. The frame 1 is equipped with an upper heating block and a linear cylinder for driving the upper heating block to rise and fall. In operation, the operator first places the interior trim parts onto the support mold 11 and then presses the interior trim parts to ensure accurate alignment with the support mold 11. Next, the sensing mechanism 3, driven by the pressure, activates the lateral clamping mechanism 2 through the control mechanism 4. The lateral clamping mechanism 2 clamps the interior trim parts from both sides, further stabilizing their position. Then, heating elements such as the heating plate 12 are used to shape the leather layer on the interior trim parts.

[0028] Reference Figures 1-4The lateral clamping mechanism 2 includes a clamping plate 21, a buffer assembly 22, and a linear actuator 23. The clamping plate 21 is connected to the linear actuator 23 via the buffer assembly 22. When the interior trim is not installed on the support mold 11, and the linear actuator 23 drives the clamping plate 21 to move toward the support mold 11 via the buffer assembly 22, the control mechanism 4 restricts the movement of the clamping plate 21, and the buffer assembly 22 is compressed.

[0029] This invention utilizes clamping plates 21, a buffer assembly 22, and a linear actuator 23 to buffer the impact on the interior trim parts during clamping. Simultaneously, through the cooperation of the buffer assembly 22 and the control mechanism 4, it prevents operators from being injured by the retraction of the clamping plates 21 due to misoperation during workpiece installation. Even if the clamping plates 21 retract, the buffer assembly 22 controls the retraction force to prevent operator injury. The buffer assembly 22 includes a push plate 221, a retractable first damping rod 222, and a first elastic element 223. The push plate 221 is connected to the drive end of the linear actuator 23. The two ends of the first damping rod 222 are connected to the push plate 221 and the clamping plate 21, respectively. The first elastic element 223 is sleeved on the first damping rod 222, and its two ends are connected to the two ends of the first damping rod 222. Before installing the interior trim, the linear actuator 23 applies pressure to the first damping rod 222 via the push plate 221, while the movement of the clamping plate 21 is hindered by the control mechanism 4. The first damping rod 222 and the first elastic element 223 contract under pressure. The operator installs the interior trim onto the support mold 11 and then presses it down. The pressing pressure is transmitted to the control mechanism 4 via the sensing mechanism 3, and the control mechanism 4 no longer restricts the movement of the clamping plate 21 toward the support mold 11. The clamping plate 21 contracts inward under the elastic force of the first elastic element 223, thereby clamping the interior trim and completing its fixation. After the shaping process is completed, the linear actuator 23 drives the push plate 221 to move away from the support mold 11, controls the clamping plate 21 to reset, and restricts the movement range of the clamping plate 21 again via the control mechanism 4.

[0030] Reference Figure 3 and Figure 6 The control mechanism 4 includes a limiting component 41 and a control component 42; both the limiting component 41 and the control component 42 are mounted on the frame 1; the limiting component 41 is used to limit the movement of the clamping plate 21; when the supporting mold 11 is subjected to a downward pressure exceeding a threshold, the sensing mechanism 3 transmits the downward pressure to the control component 42, and the control component 42 releases the limiting component 41 from restricting the movement of the clamping plate 21.

[0031] This invention achieves movement control of the clamping plate 21 through the limiting component 41 and the control component 42, resulting in automatic clamping of the interior trim after installation. When the operator presses the interior trim, the supporting mold 11 experiences downward pressure. The sensing component detects this pressure and transmits the force to the control component 42, which then releases the limiting component 41 from restricting the movement of the clamping plate 21. Next, the clamping plate 21 moves towards the supporting mold 11 under the elastic force of the first elastic element 223, thereby clamping the interior trim and improving its stability during the shaping process. Furthermore, the first damping rod 222 prevents repeated pressure fluctuations in the clamping plate 21, further enhancing its clamping stability.

[0032] Reference Figure 3 and Figure 5 The sensing mechanism 3 includes an elastic support component 31 and a transmission component 32; the two ends of the elastic support component 31 are respectively connected to the support mold 11 and the frame 1, and the elastic support component 31 is connected to the control component 42 through the transmission component 32.

[0033] This invention utilizes the elastic support component 31 and the transmission component 32 to sense the downward pressure applied to the mold 11. After the operator installs the interior trim and applies downward pressure, the elastic support component 31 contracts under pressure, and then transmits the force to the control component 42 via the transmission component 32. The control component 42 releases the restriction component 41 from restricting the movement of the clamping plate 21, and then performs a lateral clamping action.

[0034] Reference Figure 3 , Figure 6 and Figure 7 The limiting component 41 includes a first support 411, a stop 412, and a guide post 413; the first support 411 is mounted on the frame 1, the stop 412 is connected to the guide post 413; the guide post 413 is slidably engaged with the first support 411, and the first support 411 is drive-connected to the control component 42.

[0035] This invention achieves the function of restricting the movement of the clamping plate 21 through the first support 411, the stop 412, and the guide post 413. When the supporting mold 11 is in its initial state under the support of the elastic support assembly 31, the first support 411 is in an upward state. The clamping plate 21 has an inclined surface on the side near the supporting mold 11. The clamping plate 21 is in a reset state under the driving action of the linear actuator 23. When the linear actuator 23 drives the push plate 221 to move towards the supporting mold 11, the push plate 221 pushes the clamping plate 21 through the first elastic element 223. After the clamping plate 21 contacts the stop 412, its movement is blocked. When the supporting mold 11 is subjected to downward pressure and moves downward, the transmission assembly 32 drives the control assembly 42, and the control assembly 42 controls the stop 412 to move downward. Guided by the guide post 413, the stop block 412 can be stably controlled to move downwards in the vertical direction. After the stop block 412 separates from the clamping plate 21, the movement restriction on the clamping plate 21 is released, and then the clamping plate 21 is controlled to perform a lateral clamping action. After the shaping process is completed, the linear actuator 23 drives the push plate 221 to move away from the supporting mold 11. The push plate 221 drives the clamping plate 21 to move through the buffer assembly 22. When the clamping plate 21 contacts the stop block 412, it presses the inclined surface of the stop block 412, and then pushes the stop block 412 downwards until the clamping plate 21 completely passes through the stop block 412. The supporting mold 11 and the stop block 412 are reset under the elastic force of the elastic support assembly 31.

[0036] Reference Figure 3 , Figure 6 and Figure 7 The control component 42 includes a second support 421, a hinge seat 422, a third elastic element 423, a connecting rod 424, and a first rotating shaft 425. The second support 421 is mounted on the frame 1, and the hinge seat 422 is slidably mounted on the second support 421. The two ends of the third elastic element 423 are respectively connected to the second support 421 and the hinge seat 422. One end of the connecting rod 424 is hinged to the hinge seat 422, and the end of the connecting rod 424 away from the hinge seat 422 has a first straight groove. The first rotating shaft 425 is mounted on the stop block 412, and the first rotating shaft 425 slides in cooperation with the first straight groove. When the supporting mold 11 is subjected to a downward pressure exceeding a threshold, the supporting mold 11 transmits the force to the connecting rod 424 through the sensing mechanism 3.

[0037] This invention achieves the function of controlling the lifting and lowering of the stop block 412 through a second support 421, a hinge seat 422, a third elastic element 423, a connecting rod 424, and a first rotating shaft 425. A guide rod is connected to the hinge seat 422, which slides in a vertical direction. When the supporting mold 11 is pressed down, the supporting mold 11 drives the connecting rod 424 to rotate via the sensing mechanism 3, which in turn pushes the stop block 412 down, releasing the movement restriction on the clamping plate 21. After the shaping process is completed, the linear actuator 23 drives the clamping plate 21 to reset. After resetting, the supporting mold 11 resets under the elastic force of the elastic support assembly 31, while the third elastic element 423 acts as a tension spring, and the hinge seat 422 moves down under the elastic force of the third elastic element 423. The stop block 412 is controlled to reset under the coordinated action of the hinge seat 422 and the sensing mechanism 3.

[0038] Reference Figure 3 and Figure 5 The elastic support assembly 31 includes a support plate 311, a second damping rod 312, and a second elastic element 313. The support plate 311 is connected to the support mold 11, and the support plate 311 is connected to the control assembly 42 via the transmission assembly 32. The two ends of the second damping rod 312 are connected to the support plate 311 and the support mold 11, respectively. The second elastic element 313 is sleeved on the second damping rod 312, and the two ends of the second elastic element 313 are connected to the two ends of the second damping rod 312, respectively.

[0039] This invention utilizes a support plate 311, a second damping rod 312, and a second elastic element 313 to sense the downward pressure acting on the support mold 11. When the operator presses the interior trim to push the support mold 11 downward, the support mold 11 drives the support plate 311 downward, and the second damping rod 312 and the second elastic element 313 contract under the downward pressure. Simultaneously, the support plate 311 drives the connecting rod 424 to rotate via the transmission assembly 32, and then, through the control assembly 42 and other parts, drives the stop block 412 downward, releasing the movement restriction on the clamping plate 21.

[0040] Reference Figure 3 and Figure 6 The transmission component 32 includes a connecting block 321 and a second rotating shaft 322; the connecting block 321 is connected to the support plate 311; a second straight groove extending in the horizontal direction is provided on the connecting block 321, the second rotating shaft 322 is slidably mounted on the second straight groove, and the second rotating shaft 322 is connected to the control component 42 in a transmission connection.

[0041] This invention achieves the function of driving the connecting rod 424 to rotate when the support plate 311 moves downward through the connecting block 321 and the second rotating shaft 322. The second rotating shaft 322 is rotatably connected to the connecting rod 424, and the hinge point between the second rotating shaft 322 and the connecting rod 424 is located between the hinge seat 422 and the first straight groove. When the support plate 311 moves downward, it drives the connecting block 321 to move downward synchronously. The connecting block 321 pushes the second rotating shaft 322 to move downward. At this time, the second rotating shaft 322 will push the connecting rod 424 to move downward. When the hinge seat 422 moves downward to abut against the second support 421, it stops moving downward. At this time, pushing the second rotating shaft 322 will push the connecting rod 424 to rotate around the hinge seat 422, and then push the stop block 412 downward through the first rotating shaft 425, thereby releasing the movement restriction on the clamping plate 21.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
