The working conditions of the hot pressing equipment are closely related to the different fabrics, glue, adjustment process, temperature, pressure and time of the plastic parts. Therefore, the hot pressing and hemming machine can be used to process different thermoplastic automobile interior parts. With the rapid development of the automobile industry and the continuous improvement of consumers' requirements for automobile interior quality, the manufacturing technology and process level of automobile interior parts are also constantly improving. Therefore, the development of an efficient and precise hot pressing and hemming machine is of great significance to improving the production efficiency and quality of automobile interior parts.

[0003] However, traditional hot press hemming machines for thermoplastic automotive interior parts often lack a flexible fixing mechanism during operation, which causes the interior parts to easily shift or deform during the pressing process, thus affecting the accuracy and quality of the hemming.

DETAILED DESCRIPTION

[0036] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0037] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0038] Reference Figure 1-Figure 9As shown, a thermoplastic automotive interior trim hot press hemming machine comprises: a support member, a lower die 102 fixedly mounted on the support member, and an upper die 103 slidable up and down and mounted on the support member for use with the lower die 102; wherein the upper die 103 is slidably mounted on the support member via a lifting member and a heating member is fixedly mounted inside the upper die 103, a clamping mechanism 200 for clamping and fixing automotive interior trims of different sizes is disposed on the lower die 102, and a pressure regulating mechanism 300 for adjusting the distance between the upper die 103 and the lower die 102 so as to adjust the pressure of the upper die 103 during hot pressing is disposed on the lifting member.

[0039] When in use, the automobile interior decoration part to be hot-pressed is placed on the lower mold 102, and the interior decoration part is clamped and fixed by the clamping mechanism 200. According to the material, thickness and hot-pressing requirements of the interior decoration part, the initial distance between the upper mold 103 and the lower mold 102 is adjusted by the pressure adjustment mechanism 300 to preset a suitable hot-pressing pressure, and the heating element is started to preheat the upper mold 103 until the set hot-pressing temperature is reached. The lifting element starts to work, driving the upper mold 103 to slowly descend until it contacts the interior decoration part and starts hot-pressing. During the hot-pressing process, the pressure adjustment mechanism 300 can fine-tune the distance between the upper mold 103 and the lower mold 102 according to actual needs to maintain a constant hot-pressing pressure. After the hot pressing is completed, the lifting member drives the upper mold 103 to rise and leave the interior decoration part. The clamping mechanism 200 is released, allowing the interior decoration part that has completed hot pressing to be taken out. The pressure regulating mechanism 300 can be used to accurately control the distance between the upper mold 103 and the lower mold 102, so as to achieve precise adjustment of the hot pressing pressure and ensure the hot pressing quality of the interior decoration part. The clamping mechanism 200 is flexibly designed and can adapt to automotive interior decoration parts of different sizes and shapes, thereby improving the versatility and flexibility of the equipment. At the same time, the pressure regulating mechanism 300 is equipped with a corresponding protection mechanism, which can automatically adjust or stop working when the pressure exceeds a preset threshold value to prevent damage to the equipment or interior decoration parts due to excessive pressure.

[0040] Reference Figure 4-Figure 5 As shown, the clamping mechanism 200 includes: a clamping block 201 and a first roller 203; wherein, the clamping block 201 is provided with two groups and slides through the two side surfaces of the lower mold 102 away from each other, the side surface of the lower mold 102 is provided with an avoidance groove 204 for the two groups of clamping blocks 201 to slide, the bottom surfaces of the two groups of clamping blocks 201 are respectively rotatably provided with a first roller 203, the support member is provided with a slide groove 202 for the first roller 203 to slide, and the lower mold 102 is provided with an adjustment component 500 for adjusting the distance between the two groups of clamping blocks 201.

[0041] In the above scheme, the automobile interior decoration parts to be hot-pressed are placed in the central position of the lower mold 102, ensuring that the adjustment component 500 is in the initial state. At this time, the two groups of clamping blocks 201 are located at the outermost position, leaving enough space for the interior decoration parts. The adjustment component 500 is started, and the two groups of clamping blocks 201 are slid toward the center of the interior decoration parts along the avoidance groove 204 through mechanical transmission or electric drive. As the clamping blocks 201 move, the first rollers 203 on the bottom surface thereof roll in the slide grooves 202 on the support member to ensure that the clamping blocks 201 move smoothly. When the two groups of clamping blocks 201 contact and clamp the interior decoration parts, the adjustment component 500 stops working and maintains the clamping state. At this time, the interior decoration parts have been firmly clamped on the lower mold 102, and subsequent hot pressing preparations can be carried out. Through the design of the two groups of clamping blocks 201 and the first rollers 203, stable clamping of automobile interior decoration parts of different sizes and shapes can be achieved, ensuring that the interior decoration parts will not shift or deform during the hot pressing process.

[0042] Reference Figure 4-Figure 7 As shown, the adjustment component 500 includes: a sliding rack 501, a first gear 502, a second gear 503 and a driving rack 504; wherein, the driving rack 504 corresponds one-to-one to the clamping block 201 and is arranged on the side of the clamping block 201, and the inner wall of the lower mold 102 is provided with a second gear 503 rotating through a rotating shaft, and the second gear 503 corresponds one-to-one to the driving rack 504 and meshes with each other respectively, and the first gear 502 is fixed on the rotating shaft, and a sliding rack 501 is slidably penetrated between the two groups of first gears 502 in the lower mold 102, and the first gears 502 are meshed with the sliding rack 501, and a driving module 400 for driving the sliding rack 501 to slide up and down in the vertical direction is fixed on the lifting member.

[0043] When in use, start the driving module 400 on the lifting member, and the driving module 400 drives the sliding rack 501 to slide downward in the vertical direction. Since the sliding rack 501 is meshed with the two groups of first gears 502, as the sliding rack 501 slides down, the two groups of first gears 502 will rotate simultaneously, and the rotation of the first gear 502 drives the second gear 503 on its rotating shaft to rotate. Since the second gear 503 corresponds to the driving rack 504 one by one and meshes with each other, the rotation of the second gear 503 will drive the driving rack 504 to move in the horizontal direction. The movement of the driving rack 504 drives the clamping block 201 connected thereto to slide in the avoidance groove 204, so that the two groups of clamping blocks 201 move toward the center of the interior decoration until the interior decoration is clamped. Through the linkage design of the sliding rack 501, the first gear 502, the second gear 503 and the driving rack 504, the synchronous adjustment of the two groups of clamping blocks 201 is achieved, ensuring the balance and stability of the clamping. By adjusting the up and down sliding distance of the sliding rack 501, the moving distance and clamping force of the clamping block 201 can be accurately controlled to meet the clamping requirements of different interior parts.

[0044] Reference Figure 6 As shown, a spring column 505 is vertically fixed on the top of the sliding rack 501 , and a top block 506 is fixed on the top of the spring column 505 , and the top block 506 slides through the lower mold 102 .

[0045] In the above scheme, when the sliding rack 501 is at the bottom of its stroke, the spring column 505 is in a stretched state, and the top block 506 is close to the top of the lower mold 102. After the hot pressing and hemming are completed, the lifting member rises, driving the sliding rack 501 to rise, so that the two clamping blocks 201 move away from each other to release the interior decoration. At the same time, the spring column 505 begins to release energy, pushing the top block 506 to move upward, so that the top block 506 removes the interior decoration from the lower mold 102 to prevent the interior decoration from sticking to the lower mold 102.

[0046] Reference Figure 5-Figure 7 As shown, the driving module 400 includes: a fixed block 401, a connecting rod 403, a connecting block 404 and a limit block 405; wherein, the fixed block 401 is fixedly arranged on the lifting member, and a limit block 405 is fixedly arranged on the side, a limit groove 402 for the limit block 405 to slide is opened on the support member, a connecting rod 403 is vertically fixedly arranged on the bottom surface of the fixed block 401, a connecting block 404 is fixedly arranged on the bottom surface of the connecting rod 403, and the connecting block 404 is fixedly connected to the bottom surface of the sliding rack 501.

[0047] In the above scheme, the lifting member begins to descend, driving the fixed block 401, the connecting rod 403, the connecting block 404 and the sliding rack 501 connected thereto to move downward together, and the limit block 405 slides in the limit groove 402 to ensure the stable movement of the drive module 400 in the vertical direction and avoid lateral displacement. As the sliding rack 501 descends, the clamping block 201 begins to move towards and clamp the interior decoration part through the gear transmission mechanism. When the clamping block 201 clamps the interior decoration part, the lifting member stops descending. At this time, the sliding rack 501 remains in an appropriate position and the clamping state is stable.

[0048] Reference Figure 8-Figure 9 As shown, the lifting member includes: a hydraulic rod 104 and a mounting box 105; the hydraulic rod 104 is fixed on the support member, its output shaft is vertically downward and the mounting box 105 is fixed on the top, and the fixing block 401 is fixed on the side of the mounting box 105.

[0049] When the thermoplastic automotive interior hot pressing hemming machine starts working, the hydraulic system is first started to put the hydraulic rod 104 into working state. As the output shaft of the hydraulic rod 104 moves vertically downward, the installation box 105 also descends. In this process, the fixing block 401 remains on the side of the installation box 105 and moves with the installation box 105.

[0050] Reference Figure 8-Figure 9 As shown, the pressure regulating mechanism 300 includes: an electric telescopic rod 301, a driving block 302, a sliding connecting rod 303, a driving roller 304 and a spring 305; wherein, the sliding connecting rod 303 slides through the installation box 105, the upper mold 103 is fixedly arranged on the bottom surface of the sliding connecting rod 303, the top of the sliding connecting rod 303 is located in the installation box 105 and is fixedly provided with a driving roller 304, and the sliding connecting rod 303 is also sleeved with a spring 305, and the two ends of the spring 305 are respectively abutted against the inner side wall of the installation box 105 and the bottom surface of the driving roller 304, the electric telescopic rod 301 is fixedly arranged on the side of the installation box 105, and its output shaft is horizontally arranged and fixedly connected with a wedge-shaped driving block 302, and the inclined surface of the driving block 302 is in contact with the surface of the driving roller 304.

[0051] In the above scheme, when the pressure regulating mechanism 300 is not started, the sliding connecting rod 303 is maintained in a relatively stable initial position by the elastic force of the spring 305. At this time, a certain distance is maintained between the upper mold 103 and the installation box 105 to adapt to automobile interior decoration parts of different thicknesses. When it is necessary to adjust the pressure of the upper mold 103 on the interior decoration parts, the electric telescopic rod 301 is started. The output shaft of the electric telescopic rod 301 begins to move horizontally, driving the wedge-shaped driving block 302 to move together. As the driving block 302 moves, its inclined surface gradually contacts the surface of the driving roller 304 and generates an extrusion force. Since the driving roller 304 is fixedly connected to the sliding connecting rod 303, this extrusion force will be converted into a thrust on the sliding connecting rod 303. Under the action of the thrust, the sliding connecting rod 303 begins to overcome the elastic force of the spring 305 and slides downward along the guide structure of the installation box 105. During this process, the spring 305 is further compressed, storing more elastic potential energy. The downward movement of the sliding connecting rod 303 drives the lower mold 102 to descend, thereby reducing the gap between the upper mold 103 and the interior decoration, and increasing the pressure on the interior decoration. When the electric telescopic rod 301 stops moving, the extrusion force between the driving block 302 and the driving roller 304 remains unchanged, and the sliding connecting rod 303 and the upper mold 103 also remain in a new stable position. At this time, the hot press hemming machine can work under the set pressure. When it is necessary to release the pressure or reset, the electric telescopic rod 301 is reversed to separate the driving block 302 from the driving roller 304. Under the elastic force of the spring 305, the sliding connecting rod 303 automatically rises and resets, driving the upper mold 103 back to the initial position.

[0052] Reference Figure 8 As shown, a limiting column 306 for limiting the sliding connection rod 303 to slide up and down in the vertical direction is fixedly provided on the bottom surface of the installation box 105.

[0053] In the above scheme, the sliding connecting rod 303 cooperates with the limiting column 306 through its upper groove, so that the sliding connecting rod 303 can slide up and down in the vertical direction under the guidance of the limiting column 306. When it is necessary to adjust the pressure of the lower mold 102 on the interior decoration, the electric telescopic rod 301 is started, and the driving block 302 pushes the driving roller 304, thereby pushing the lower mold 102 downward through the sliding connecting rod 303. In this process, the limiting column 306 always keeps in contact with the sliding connecting rod 303 to ensure the stability and accuracy of its vertical sliding. The setting of the limiting column 306 effectively prevents the sliding connecting rod 303 from deflecting or shaking during the sliding process, thereby improving the stability and accuracy of pressure adjustment.

[0054] Reference Figure 8As shown, a pressure sensor 307 is fixedly provided on the upper mold 103, and a controller 308 is fixedly provided on the mounting box 105. The controller 308 is electrically connected to the pressure sensor 307 and the electric telescopic rod 301 respectively. When the pressure detection value of the pressure sensor 307 exceeds a preset pressure threshold range, the controller 308 controls the electric telescopic rod 301 to retract and drive the driving block 302 away from the driving roller 304.

[0055] In the above scheme, the pressure sensor 307 fixed on the upper mold 103 monitors the pressure applied by the upper mold 103 to the automobile interior in real time, and transmits the detected pressure value to the controller 308. After receiving the pressure value transmitted by the pressure sensor 307, the controller 308 immediately compares it with the preset pressure threshold range. This preset pressure threshold range is set in advance according to factors such as the material properties of the automobile interior, the requirements of hot pressing hemming, etc. If the pressure value detected by the pressure sensor 307 exceeds the upper limit of the preset pressure threshold range, the controller 308 will immediately send a control signal to the electric telescopic rod 301. After receiving the control signal, the electric telescopic rod 301 begins to shrink back, driving the driving block 302 on its output shaft away from the driving roller 304. This action will reduce the thrust on the sliding connecting rod 303, thereby causing the upper mold 103 to rise and release part of the pressure. As the upper mold 103 rises, the pressure sensor 307 continues to monitor the pressure value and feeds back the new pressure value to the controller 308. When the pressure value returns to the preset pressure threshold range, the controller 308 stops sending control signals to the electric telescopic rod 301 and maintains the current pressure state. During the entire hot pressing and hemming process, the controller 308 will continue to monitor the detection value of the pressure sensor 307 and adjust the working state of the electric telescopic rod 301 as needed to ensure that the pressure applied by the upper mold 103 to the interior decoration parts is always maintained within an appropriate range. Accurately controlling the pressure of the upper mold 103 on the interior decoration parts helps to achieve a more uniform and consistent hemming effect and improve the overall quality and appearance of the product.

[0056] Reference Figure 1-Figure 4 As shown, the support member includes: an operating table 100 and a support frame 101, the lower mold 102 is fixed on the operating table 100, the operating table 100 is provided with a slide groove 202 for the first roller 203 to slide, the support frame 101 is vertically fixed on the upper surface of the operating table 100, the hydraulic rod 104 is fixed on the top of the support frame 101, and the support frame 101 is also provided with a limit groove 402 for the limit block 405 to slide.

[0057] After the thermoplastic automotive interior hot press hemming machine is assembled, the operating table 100 is firmly placed on the ground, the support frame 101 is vertically fixed to the upper surface of the operating table 100, the lower mold 102 is fixed to a designated position of the operating table 100 for placing the automotive interior to be processed, the hydraulic rod 104 is fixedly mounted on the top of the support frame 101, and its output shaft extends vertically downward, the mounting box 105 is fixed to the top of the output shaft of the hydraulic rod 104, and is used to carry subsequent lifting and hemming operation components, and a slide groove 202 is provided on the operating table 100 for the first roller 20 3 slides to realize automatic feeding or positioning of the interior decoration parts. A limiting groove 402 is provided on the support frame 101 for sliding of the limiting block 405 to ensure stability and accuracy during the lifting process. The hydraulic system is started, and the hydraulic rod 104 starts to work to push the installation box 105 and the components thereon to move vertically downward. During this process, the limiting block 405 slides along the limiting groove 402 on the support frame 101 to ensure accuracy and stability in the lifting direction. When the lifting mechanism descends to a predetermined position, the lower mold 102 contacts the interior decoration parts and starts the hot pressing hemming operation.
