[0002] Automotive interior parts are the components used for decoration inside the car body, generally referring to the partitions, door trim panels, instrument panel assemblies, armrests and other parts of the car compartment. Although interior parts are only some auxiliary spare parts, they have to assume the functions of vibration reduction, heat insulation, sound absorption and sound insulation, and play a very important role in the comfort of the vehicle.

[0015] The beneficial effects of the present invention are:

[0016] 1) Automatic loading and unloading can be achieved through the blanking mechanism and the material transfer mechanism, which reduces manual participation, has a high degree of automation, and reduces the labor intensity of manual labor. At the same time, the blanking mechanism, material transfer mechanism, hot pressing mechanism, and cooling mechanism can work synchronously, thereby improving production efficiency.

[0017] 2) When the hot pressing mechanism is working, it presses the sheet metal down into the forming groove. During this process, the top plate and the movable rod are subjected to downward pressure and move downward until the top plate moves into the circular groove. At this time, the first spring is in a compressed state. When the hot pressing mechanism moves upward, the automotive interior parts in the forming groove are lifted up along the forming groove under the action of the first spring and the top plate, which is convenient for the subsequent cooling and material transfer operations of the automotive interior parts.

[0018] 3) The diameter of the through groove is smaller than the diameter of the circular groove. The through groove is used for the passage of the first spring and prevents the top plate from entering the through groove.

[0019] 4) When the upper die contacts the upper surface of the sheet, the suction cup at the bottom of the piston cylinder also contacts the upper surface of the sheet. When the third telescopic cylinder drives the heating device and the upper die to move downward, the rack connected to the heating device moves downward accordingly, thereby driving the gear to rotate. After the gear rotates, it drives the rack on the side away from the third telescopic cylinder to move upward, and the U-shaped rod on the rack drives the piston to move upward along the piston cylinder. At this time, the interior of the piston cylinder is in a negative pressure state, and the sheet is adsorbed by the suction cup. After the hot pressing of the sheet is completed, the third telescopic cylinder drives the heating device and the upper die to move upward, and the piston in the piston cylinder moves downward along the piston cylinder. At this time, the interior of the piston cylinder is no longer in a negative pressure state, and the suction cup cannot adsorb the hot-pressed automotive interior parts, thereby separating the upper die from the hot-pressed automotive interior parts, avoiding the adhesion between the upper die and the hot-pressed automotive interior parts, ensuring the normal progress of subsequent work, and being conducive to improving work efficiency.

[0020] 5) Ice cubes and water are added to the water tank through the water inlet pipe. The ice cubes can cool the water. The water in the water tank is transported to the circulation pipe through the water pump. At the same time, the fan is working. The gas in and out of the U-shaped plate by the fan can reduce the temperature of the gas after contacting the circulation pipe. Finally, it is blown to the hot-pressed automotive interior parts through the air outlet pipe, which can quickly cool them down and improve work efficiency.

[0021] 6) The gas blown in by the fan can be filtered through the filter cotton and the filter net to prevent the dust in the gas from falling on the car interior parts. Since the car interior parts are not cooled after hot pressing, the dust in the gas will stick to the car interior parts if it falls on them, which is inconvenient for later processing. By setting the filter net and filter cotton, the quality of the finished car interior parts is guaranteed.

[0022] 7) Place multiple sheets in the bearing slot. In the original state of the L-shaped plate, the U-shaped slot does not overlap with the bearing slot. The sheet inside the bearing slot is blocked by the L-shaped plate and cannot move downward. When blanking is required, one of the lower die mechanisms is located directly below the bearing slot. The first telescopic cylinder works and extends to drive the L-shaped plate to slide along the slide slot, so that the L-shaped plate moves to one side of the bearing slot. During this process, the extrusion rod on the L-shaped plate also moves accordingly. After the L-shaped plate moves a certain distance, the extrusion rod first contacts the second sheet at the bottom and fixes this sheet. At this time, the second spring is in a compressed state, and then the first telescopic cylinder continues to drive the L-shaped plate to move. When the U-shaped slot on the L-shaped plate overlaps with the bearing slot on the base, the extrusion rod on the bearing The sheet material at the bottom of the groove is no longer blocked by the L-shaped plate and moves downward, and falls on the top of the lower die mechanism. After the blanking is completed, the first telescopic cylinder contracts and drives the L-shaped plate to move in the opposite direction. The U-shaped groove on the L-shaped plate and the bearing groove on the base no longer overlap, and the L-shaped plate blocks the bearing groove. At this time, the second spring gradually returns to its original state. When the L-shaped plate moves a certain distance, the extrusion rod no longer contacts the sheet material in the bearing groove, and the sheet material away from the extrusion rod moves downward along the bearing groove and contacts the L-shaped plate, waiting for the next blanking. The blanking mechanism does not need to manually place the sheet material on the lower die mechanism, and multiple sheets only need to be placed in the bearing groove at one time, which reduces the labor intensity of workers and improves work efficiency.

[0023] 8) When the cooled automobile interior decoration parts need to be taken out from the lower mold mechanism, the first motor works to drive the second rotating shaft to rotate, and the cam located on the second rotating shaft rotates accordingly. When the pin on the first rotating rod contacts the first arc groove, the first rotating rod and the second rotating rod away from the first rotating shaft at one end rotate counterclockwise along the first rotating shaft at the same time, and the pressure rod located on the second rotating rod moves accordingly to press down the bottom plate, thereby driving the lifting rod to move downward, and the bearing rod connected to the lifting rod through the connecting plate drives the vacuum cylinder to move downward. When the pin is located at the junction of the first arc groove and the second arc groove, the vacuum cylinder moves to the lowest position, and the vacuum cylinder works to adsorb the automobile interior decoration parts. When the pin on the first rotating rod contacts the second arc groove, the first rotating rod and the second rotating rod away from the first rotating shaft at one end rotate clockwise along the first rotating shaft at the same time, and the pressure rod located on the second rotating rod moves accordingly and no longer presses down the bottom plate, thereby driving the lifting rod to move upward, and the bearing rod connected to the lifting rod through the connecting plate drives the vacuum cylinder The air cylinder moves upward, and when the pin is located at the junction of the second arc groove and the third arc groove, the vacuum cylinder moves to its original position. In this process, the arc plate on the second rotating shaft moves into one of the U-shaped openings to prevent rotation. When the pin is located in the third arc groove, the height of the lifting rod remains unchanged, the lever enters one of the arc grooves through the U-shaped opening, and separates from the rotating drum from the other U-shaped opening. The U-shaped opening through which the lever enters the rotating drum and the U-shaped opening through which the lever leaves the rotating drum are not on the same horizontal plane. The lever can make the rotating drum drive the lifting rod to rotate 90°, so that the vacuum cylinder is located above the conveyor belt, and then repeat the above steps to drive the lifting rod to move downward. When the vacuum cylinder moves to the lowest point, the automotive interior parts are placed on the conveyor belt, and the automotive interior parts are moved to the collection point through the conveyor belt. There is no need to manually collect the automotive interior parts on the lower mold mechanism one by one, which reduces the labor intensity of workers and improves work efficiency.

[0024] 9) After the upper mold is heated to a certain temperature by the heating device, the second telescopic cylinder works and extends to drive the movable plate to move downward, and the heating device and the upper mold on the movable plate move downward accordingly until the upper mold contacts the upper surface of the sheet material, and then the second telescopic cylinder stops working. The upper mold with a certain temperature heats and softens the sheet material. After the upper mold contacts the sheet material for a certain period of time, the third telescopic cylinder works and extends to drive the upper mold to move downward, and the sheet material is hot-pressed by the joint action of the upper mold and the lower mold.

[0045] A hot pressing forming device for automobile interior decoration parts comprises a base 1, a workbench 2, a lower mold mechanism 3, a hot pressing mechanism 5, and a cooling mechanism 6. The workbench 2 is mounted on the base 1 through a rotating mechanism 9. The number of the lower mold mechanisms 3 is four and they are mounted on the workbench 2 at equal angles. The interval between two adjacent lower mold mechanisms 3 is 90°. The hot pressing mechanism 5 and the cooling mechanism 6 are both arranged on the periphery of the workbench 2 and mounted on the base 1. The interval between the hot pressing mechanism 5 and the cooling mechanism 6 is 90°. A blanking mechanism 4 is provided on the opposite side of the cooling mechanism 6.

A conveyor belt 8 is provided between the transfer mechanism 7 and the blanking mechanism 4 and on one side of the base 1.

[0046] The rotating mechanism 9 includes a shell 901, a second motor 902, a worm 903, a third rotating shaft 904, and a worm wheel 905. The third rotating shaft 904 is rotatably mounted on the base 1. The top of the third rotating shaft 904 is connected to the workbench 2. The worm wheel 905 is mounted on the third rotating shaft 904. The shell 901 is located outside the worm wheel 905 and is mounted on the base 1. The worm 903 is located on one side of the worm wheel 905 and is rotatably mounted inside the shell 901. The worm 903 is meshedly connected with the worm wheel 905. The second motor 902 is mounted outside the shell 901 and the end of the output shaft is connected to one end of the worm 903. The second motor 902 drives the worm 903 to rotate when it works. After the worm 903 rotates, it meshes with the worm wheel 905 to drive the third rotating shaft 904 to rotate, and the workbench 2 connected to the third rotating shaft 904 rotates accordingly, thereby driving the lower mold mechanism 3 on the workbench 2 to rotate.

[0047] The lower die mechanism 3 includes a lower die 301, a movable rod 304, and a first spring 306. The lower die 301 is installed on the workbench 2 through two lower end pads 302. A molding groove 303 is provided inside the lower die 301. There are two movable rods 304, which are symmetrically slidably installed on the workbench 2.

The movable end of the third telescopic cylinder 507 passes through the movable plate 503 and is installed with a heating device 508. The upper mold 509 is installed at the bottom of the heating device 508. The upper mold 509 is heated by the heating device 508. After being heated to a certain temperature, the second telescopic cylinder 502 extends and drives the movable plate 503 to move downward, and the heating device 508 and the upper mold 509 on the movable plate 503 move downward accordingly, until the upper mold 509 contacts the upper surface of the sheet material 10, and then the second telescopic cylinder 502 stops working, and the upper mold 509 with a certain temperature heats and softens the sheet material 10. After the upper mold 509 contacts the sheet material 10 for a certain period of time, the third telescopic cylinder 507 extends and drives the upper mold 509 to move downward, and the sheet material 10 is hot-pressed by the joint action of the upper mold 509 and the lower mold 301. A support frame 504 is provided above the movable plate 503 and on both sides of the third telescopic cylinder 507, and the support frame 504 is U-shaped and inverted.

When the upper mold 509 contacts the upper surface of the sheet material 10, the suction cup 514 located at the bottom of the piston cylinder 510 also contacts the upper surface of the sheet material 10. When the third telescopic cylinder 507 drives the heating device 508 and the upper mold 509 to move downward, the rack 506 connected to the heating device 508 moves downward accordingly, thereby driving the gear 505 to rotate. After the gear 505 rotates, it drives the rack 506 away from the side of the third telescopic cylinder 507 to move upward, and the U-shaped rod 512 located on this rack 506 drives the piston 513 to move upward along the piston cylinder 510.At this time, the interior of the piston cylinder 510 is in a negative pressure state, and the sheet material 10 is sucked by the suction cup 514. After the hot pressing of the sheet material 10 is completed, the third telescopic cylinder 507 drives the heating device 508 and the upper mold 509 to move upward, and the piston 513 located in the piston cylinder 510 moves downward along the piston cylinder 510. At this time, the interior of the piston cylinder 510 is no longer in a negative pressure state, and the suction cup 514 cannot suck the hot pressed automobile interior parts, so that the upper mold 509 is separated from the hot pressed automobile interior parts, avoiding the adhesion between the upper mold 509 and the hot pressed automobile interior parts, ensuring the normal progress of subsequent work, and facilitating the improvement of work efficiency.

[0049] The cooling mechanism 6 includes a U-shaped plate 601, a water tank 604, and a water pump 605.

A filter cotton 610 is provided between the fan 602 and the cap 609, and a filter screen 611 is installed at the end of the cap 609. The filter cotton 610 and the filter screen 611 can filter the gas blown in by the fan 602 to prevent dust in the gas from falling on the automobile interior decoration parts. Since the automobile interior decoration parts are not cooled after hot pressing, the dust in the gas will adhere to the automobile interior decoration parts if it falls on the automobile interior decoration parts, which is inconvenient for later processing. By providing the filter screen 611 and the filter cotton 610, the finished product quality of the automobile interior decoration parts is guaranteed.

[0050] The blanking mechanism 4 includes a base 401, an L-shaped plate 405, a first telescopic cylinder 407, and an extrusion rod 409. The base 401 is installed on the base 1.

The slide groove 403 and the bearing groove 402 are perpendicular to each other. The L-shaped plate 405 is slidably installed in the slide groove 403. A U-shaped groove 412 is provided in the middle of the slide groove 403. The width of the shaped groove 412 is greater than the width of the bearing groove 402. The extrusion rod 409 is slidably installed on the L-shaped plate 405. One end of the extrusion rod 409 passes through the L-shaped plate 405 and is installed with a limiting plate 410.

When blanking is required, one of the lower mold mechanisms 3 is located directly below the bearing groove 402, and the first telescopic cylinder 407 is extended to drive the L-shaped plate 405 to slide along the slide groove 403, so that the L-shaped plate 405 moves to one side of the bearing groove 402. In this During the process, the extrusion rod 409 on the L-shaped plate 405 also moves accordingly. After the L-shaped plate 405 moves a certain distance, the extrusion rod 409 first contacts the second sheet material 10 at the bottom and fixes the sheet material 10. At this time, the second spring 406 is in a compressed state, and then the first telescopic cylinder 407 continues to drive the L-shaped plate 405 to move. When the U-shaped groove 412 on the L-shaped plate 405 coincides with the bearing groove 402 on the base 401, the sheet material 10 at the bottom of the bearing groove 402 is no longer blocked by the L-shaped plate 405 and moves downward, and falls on the top of the lower mold mechanism 3. After the blanking is completed, the first telescopic cylinder 407 contracts and drives the L-shaped plate 405 to move in the opposite direction, and the U-shaped groove 412 on the L-shaped plate 405 no longer coincides with the bearing groove 402 on the base 401.The L-shaped plate 405 blocks the bearing slot 402, and the second spring 406 gradually returns to its original state. When the L-shaped plate 405 moves a certain distance, the extrusion rod 409 no longer contacts the sheet 10 in the bearing slot 402, and the sheet 10 fixed by the extrusion rod 409 moves downward along the bearing slot 402 and contacts the L-shaped plate 405, waiting for the next blanking. Through the blanking mechanism 4, there is no need to manually place the sheet 10 on the lower die mechanism 3, and multiple sheets 10 only need to be placed in the bearing slot 402 at one time, which reduces the labor intensity of workers and improves work efficiency.
