[0018] The usage method includes the following steps:

[0019] First step, first place the automotive interior trim panel inside the outer shaping mold, then place the outer shaping mold on the conveyor belt, and limit and fix the outer shaping mold through an electric clamping frame, so that the conveyor belt can convey the outer shaping mold and the automotive interior trim panel from left to right;

[0020] Step 2: When the outer shaping mold moves directly below the inner shaping mold, the conveyor belt stops rotating. Then, the electric clamping bracket releases the outer shaping mold and no longer clamps and fixes it. At this time, through the electromagnetic suction plates on the outer shaping mold and the inner shaping mold, the outer shaping mold can be adsorbed upward onto the inner shaping mold. At this time, the outer shaping mold disengages from the conveyor belt, and the outer joint is inserted into the inner joint, so that the cooling inner cavity and the cooling outer cavity are connected. Then, start the rotating motor to drive the L-shaped lock block to rotate, so that the L-shaped lock block can be movably clamped with the L-shaped lock groove, and thus the outer shaping mold can be fixed on the inner shaping mold, and the outer shaping mold and the inner shaping mold are closed to form a mold cavity;

[0021] Step 3: Then, rotate the driving roller counterclockwise, and through the meshing of the driving tooth ring with the driven tooth rings on both sides, the cooling roller and the demolding roller can be driven to rotate clockwise. When the position sensors on the feeding die base and the cooling die base detect each other's positions, stop the driving roller and the cooling roller from rotating. At this time, the outer shaping mold is located inside the cooling die base. At the same time, the insertion tube is inserted into the coolant pressure valve and opens it. Then, the cooling pump can transport the coolant to the cooling outer cavity through the infusion rotating tube, the infusion fixed tube, the inner fixed tube, the sliding tube, and the insertion tube. The coolant inside the cooling outer cavity can be transported to the cooling inner cavity through the inner joint and the outer joint, and cool the outer shaping mold and the inner shaping mold, so that the automotive interior panel inside the mold cavity can be cooled and shaped;

[0022] Step 4: After the automotive interior panel inside the mold cavity is cooled and shaped, rotate the driving roller again, so that the driving roller can rotate the shaped outer shaping mold and the inner shaping mold to the demolding roller. When the position sensors on the feeding die base and the demolding base detect each other's positions, stop rotating the driving roller and the demolding roller again. At this time, the outer shaping mold is located inside the demolding base. At the same time, the insertion tube is inserted into the air pressure valve and opens it. Then, the air pump can transport the gas to the inside of the mold cavity through the air delivery rotating tube, the air delivery fixed tube, the inner fixed tube, the sliding tube, and the insertion tube, so as to inject the gas into the gap between the automotive interior panel and the mold cavity, and thus the automotive interior panel can be separated from the inner walls of the outer shaping mold and the inner shaping mold. Then, rotate the outer shaping mold to above the conveyor belt through the driving roller, and then reverse the rotating motor so that the L-shaped lock block no longer fixes the outer shaping mold and the inner shaping mold. At the same time, cut off the power supply of the electromagnetic suction plate so that the outer shaping mold and the inner shaping mold are no longer magnetically fixed, so that the outer shaping mold and the automotive interior panel inside it fall onto the conveyor belt together. The conveyor belt continues to transport the outer shaping mold and the automotive interior panel to the right and out of the outside of the chassis, and they are sorted manually.

[0023] (III) Beneficial effects

[0024] The present invention provides a method for using a shaping tool for automotive interior panels. It has the following beneficial effects:

[0025] 1. After the outer shaping mold moves to directly below the inner shaping mold, the clamping frame releases the outer shaping mold and no longer clamps and fixes it. The electromagnetic suction plates on the outer shaping mold and the inner shaping mold can adsorb the outer shaping mold upward onto the inner shaping mold. The outer joint is inserted into the inner joint, and the cooling inner cavity and the cooling outer cavity are connected. Then, start the rotating motor to drive the L-shaped lock block to rotate by 90 degrees, so that the L-shaped lock block can be movably clamped with the L-shaped lock groove. Therefore, the outer shaping mold can be fixed on the inner shaping mold, and the outer shaping mold and the inner shaping mold are closed to form a mold cavity.

[0026] 2. After the position sensors on the feeding die base and the cooling die base detect each other's positions, stop the driving roller and the cooling roller from rotating. The outer shaping mold is located inside the cooling die base, and the insertion tube is inserted into the coolant pressure valve and opens it. The cooling pump can deliver the coolant to the cooling outer cavity through the liquid delivery rotating tube, the liquid delivery fixed tube, the inner fixed tube, the sliding tube, and the insertion tube. The coolant inside the cooling outer cavity can be delivered to the cooling inner cavity through the inner joint and the outer joint. Furthermore, the coolant inside the cooling outer cavity and the cooling inner cavity can cool down the outer shaping mold and the inner shaping mold, so that the automotive interior panel inside the mold cavity can be cooled and shaped.

[0027] 3. After the position sensors on the feeding die base and the demolding die base detect each other's positions, stop the driving roller and the demolding roller from rotating, and the insertion tube is inserted into the air pressure valve and opens it. At this time, the air pump can deliver the gas to the mold cavity through the air delivery rotating tube, the air delivery fixed tube, the inner fixed tube, the sliding tube, and the insertion tube, so that the gas is poured into the gap between the automotive interior panel and the inner wall of the mold cavity, and the automotive interior panel can be separated from the inner walls of the outer shaping mold and the inner shaping mold, and the automotive interior panel is demolded from the outer shaping mold and the inner shaping mold.

After the outer shaping die 18 and the inner shaping die 34 are closed, the rotating motor 313 drives the L-shaped locking block 314 to rotate 90 degrees inside the L-shaped locking groove 315. Therefore, the outer shaping die 18 and the inner shaping die 34 can be locked and fixed together by the L-shaped locking block 314, so that the automotive interior panel is inside the mold cavity 35.

[0043] Specifically, when the driving motor 11 drives the driving roller 3 to rotate, at this time, the conductive brush 31 and the conductive roller 32 rotate relative to each other, which is convenient for the conductive roller 32 to supply power to the conductive brush 31 during rotation, and the conductive brush 31 can supply power to the coolant pressure valve 38, the position sensor 311, the electromagnetic suction plate 312, and the rotating motor 313 through wires.

[0044] In this embodiment, the inner shaping die 34 and the outer shaping die 18 are magnetically fixed by the electromagnetic suction plate 312, the cooling inner cavity 36 and the cooling outer cavity 37 are connected through the inner joint 39 and the outer joint 310, and the L-shaped locking block 314 is movably clamped with the L-shaped locking groove 315;

[0046] In this embodiment, the cooling structure includes a fixed infusion pipe 41 and a rotating infusion pipe 42. The fixed infusion pipe 41 is fixed inside the cooling roller 4, the rotating infusion pipe 42 is rotatably connected inside the fixed infusion pipe 41.

T-shaped limit sliders 45 slide inside the T-shaped limit sliding grooves 43. A cooling mold base 46 is fixed on the T-shaped limit slider 45 on one side of the cooling roller 4.

[0047] Specifically, as shown in the attached drawings of the specification Figure 6 As shown, after the outer shaping mold 18 is attached to the cooling mold base 46, the insertion tube 412 is inserted into the interior of the coolant pressure valve 38 at this time and opens the coolant pressure valve 38. Then, the cooling pump 12 conveys coolant to the interiors of the cooling cavity 36 and the cooling outer cavity 37 through the liquid delivery rotating tube 42, the liquid delivery fixed tube 41, the inner fixed tube 47, the sliding tube 410, and the insertion tube 412, and cools down the outer shaping mold 18 and the inner shaping mold 34, so as to cool and shape the automotive interior panel inside the mold cavity 35.

[0048] In this embodiment, the liquid delivery fixed tube 41 is connected to the cooling pump 12, and both ends of the elastic piece 44 are fixedly connected to the inner wall of the T-shaped limiting sliding groove 43 and the T-shaped limiting sliding block 45 respectively;

Moreover, the cooling mold base 46, the demolding seat 53, and the outer shaping mold 18 are all trapezoidal. During the contact process between the outer shaping mold 18 and the cooling mold base 46 or the demolding seat 53, the T-shaped limiting sliding block 45 can be extruded outwards, enabling the T-shaped limiting sliding block 45 to drive the sliding inside the T-shaped limiting sliding groove 43 and drive the elastic piece 44 to deform, so that the outer shaping mold 18 can be attached to the cooling mold base 46 or the demolding seat 53 respectively.

[0051] Specifically, during the movement of the T-shaped limiting sliding block 45, it can drive the sliding tube 410 to slide inside the inner fixed tube 47, causing the inner fixed tube 47, the spring 49, the sliding tube 410, and the insertion tube 412 to form a spring telescopic tube to contract, so that the insertion tube 412 can be inserted into the coolant pressure valve 38.

The air delivery fixed tube 51 is fixed inside the demolding roller 5, the air delivery rotating tube 52 is rotatably connected inside the air delivery fixed tube 51. A demolding seat 53 is fixed on the surface of the demolding roller 5, and an air delivery pressure valve 54 is installed inside the mold cavity 35;

[0053] Specifically, as shown in the attached drawings of the specification Figure 6As shown, after the outer shaping mold 18 is attached to the demolding seat 53, the insertion tube 412 is inserted into the interior of the gas transmission pressure valve 54 to open the gas transmission pressure valve 54. Then, the air pump 13 can deliver gas into the interior of the mold cavity 35 through the gas transmission rotating tube 52, the gas transmission fixed tube 51, the inner fixed tube 47, the sliding tube 410, and the insertion tube 412, so as to inject gas into the gap between the automotive interior trim panel and the mold cavity 35, thereby enabling the demolding of the automotive interior trim panel from the outer shaping mold 18 and the inner shaping mold 34.

[0054] In this embodiment, the inner fixed tube 47, the spring 49, the sliding tube 410, and the insertion tube 412 form a spring telescopic tube. The inner end of the spring telescopic tube on the side of the cooling roller 4 is connected to the infusion fixed tube 41, and the inner end of the spring telescopic tube on the side of the demolding roller 5 is connected to the gas transmission fixed tube 51. The coolant pressure valve 38 is installed at the middle position of the outer shaping mold 18 and is connected to the cooling inner cavity 36. The gas transmission pressure valve 54 is installed at both sides of the outer shaping mold 18 and is connected to the mold cavity 35. The insertion tube 412 is respectively adapted to the gas transmission pressure valve 54 and the gas transmission pressure valve 54.

[0055] Specifically, the coolant pressure valve 38 is installed at the middle position of the outer shaping mold 18 and is connected to the cooling outer cavity 37, so that the coolant inside the infusion fixed tube 41 can be delivered to the cooling outer cavity 37 through the spring telescopic tube at the middle position. The gas transmission pressure valve 54 is installed at both ends of the outer shaping mold 18 and is connected to the mold cavity 35, so that the gas inside the gas transmission fixed tube 51 can be delivered to the mold cavity 35 through the spring telescopic tube at both ends.

[0056] The usage method includes the following steps:

[0057] In the first step, first place the automotive interior trim panel inside the outer shaping mold 18, then place the outer shaping mold 18 on the conveyor belt 16, and limit and fix the outer shaping mold 18 through the electric clamping bracket 17, so that the conveyor belt 16 can convey the outer shaping mold 18 and the automotive interior trim panel from left to right.

[0058] Step 2: When the outer shaping mold 18 moves to directly below the inner shaping mold 34, the conveyor belt 16 stops rotating. Then, the electric clamping bracket 17 releases the outer shaping mold 18 and no longer clamps and fixes it. At this time, through the electromagnetic suction plates 312 on the outer shaping mold 18 and the inner shaping mold 34, the outer shaping mold 18 can be adsorbed upward onto the inner shaping mold 34. At this time, the outer shaping mold 18 is separated from the conveyor belt 16, and the outer joint 310 is inserted onto the inner joint 39, enabling the cooling inner cavity 36 and the cooling outer cavity 37 to communicate. Then, the rotation motor 313 is started to drive the L-shaped locking block 314 to rotate, so that the L-shaped locking block 314 can be movably clamped with the L-shaped locking groove 315. Therefore, the outer shaping mold 18 can be fixed on the inner shaping mold 34, and the outer shaping mold 18 and the inner shaping mold 34 are closed to form a mold cavity 35;

[0059] Step 3: Then, the driving roller 3 is rotated counterclockwise, and through the meshing of the driving gear ring 21 with the driven gear rings 22 on both sides thereof, the cooling roller 4 and the demolding roller 5 can be driven to rotate clockwise. When the position sensors 311 on the feeding die base 33 and the cooling die base 46 detect each other's positions, the driving roller 3 and the cooling roller 4 stop rotating. At this time, the outer shaping mold 18 is located inside the cooling die base 46. At the same time, the insertion tube 412 is inserted into the coolant pressure valve 38 and opens it. Then, the cooling pump 12 can transport the coolant to the cooling outer cavity 37 through the liquid delivery rotating tube 42, the liquid delivery fixed tube 41, the inner fixed tube 47, the sliding tube 410, and the insertion tube 412. The coolant inside the cooling outer cavity 37 can be transported to the cooling inner cavity 36 through the inner joint 39 and the outer joint 310, and cool the outer shaping mold 18 and the inner shaping mold 34, thereby cooling and shaping the automotive interior panel inside the mold cavity 35;

[0060] Step 4: After the automotive interior trim panel inside the mold cavity 35 is cooled and shaped, rotate the driving roller 3 so that the driving roller 3 can rotate the shaped outer shaping mold 18 and inner shaping mold 34 to the demolding roller 5. When the position sensors 311 on the feeding die base 33 and the demolding base 53 detect each other's positions, stop rotating the driving roller 3 and the demolding roller 5. At this time, the outer shaping mold 18 is located inside the demolding base 53. At the same time, the insertion tube 412 is inserted into the gas transmission pressure valve 54 and opens it. Then, the air pump 13 can transport gas into the mold cavity 35 through the gas transmission rotating tube 52, gas transmission fixed tube 51, inner fixed tube 47, sliding tube 410, and insertion tube 412, so as to fill the gas into the gap between the automotive interior trim panel and the mold cavity 35, thereby enabling the automotive interior trim panel to be separated from the inner walls of the outer shaping mold 18 and the inner shaping mold 34. Then, rotate the outer shaping mold 18 above the conveyor belt 16 through the driving roller 3. Then, reverse the rotation motor 313 so that the L-shaped lock block 314 no longer fixes the outer shaping mold 18 and the inner shaping mold 34. At the same time, cut off the power supply of the electromagnetic suction plate 312 so that it no longer magnetically fixes the outer shaping mold 18 and the inner shaping mold 34, causing the outer shaping mold 18 and the automotive interior trim panel inside it to fall onto the conveyor belt 16 together. The conveyor belt 16 continues to transport the outer shaping mold 18 and the automotive interior trim panel to the right and out of the outside of the chassis 1, and is sorted manually.

[0061] Working principle and usage process of the present invention: By connecting the conveyor belt 16 to an external driving device, the conveyor belt 16 can be driven to rotate clockwise. First, place the automotive interior trim panel inside the outer shaping mold 18, then place the outer shaping mold 18 on the conveyor belt 16, and the electric clamping frame 17 limits and fixes the outer shaping mold 18 on the conveyor belt 16, enabling the conveyor belt 16 to drive the outer shaping mold 18 and the automotive interior trim panel to move to the right. At the same time, the driving motor 11 can drive the driving roller 3 to rotate counterclockwise, and through the meshing between the driving gear ring 21 and the driven gear ring 22 of the driving roller 3, the cooling roller 4 and the demolding roller 5 can be driven to rotate clockwise. When the outer shaping mold 18 moves to directly below the inner shaping mold 34, stop the rotation of the driving roller 3 and the conveyor belt 16, and then the clamping frame 17 releases the outer shaping mold 18 and no longer clamps and fixes it. At this time, the electromagnetic suction plates 312 on the outer shaping mold 18 and the inner shaping mold 34 can suck the outer shaping mold 18 upward onto the inner shaping mold 34. At the same time, the outer shaping mold 18 disengages from the conveyor belt 16, and the outer joint 310 is inserted into the inner joint 39, and the cooling inner cavity 36 and the cooling outer cavity 37 are connected. Then, start the rotation motor 313 to drive the L-shaped lock block 314 to rotate 90 degrees, enabling the L-shaped lock block 314 to be movably clamped with the L-shaped lock groove 315, so that the outer shaping mold 18 can be fixed on the inner shaping mold 34, and the outer shaping mold 18 and the inner shaping mold 34 are closed to form a mold cavity 35. Then, make the driving roller 3 and the cooling roller 4 rotate. When the position sensors 311 on the feeding die base 33 and the cooling die base 46 detect each other's positions, stop the rotation of the driving roller 3 and the cooling roller 4. At this time, the outer shaping mold 18 is located inside the cooling die base 46, and the outer shaping mold 18 presses on the cooling die base 46, causing the T-shaped limit slider 45 to move inside the T-shaped limit sliding groove 43, so as to enable the outer shaping mold 18 to fit with the cooling die base 46. When the outer shaping mold 18 presses on the cooling die base 46, the insertion tube 412 is inserted into the coolant pressure valve 38 and opens it. At this time, the cooling pump 12 can transport the coolant to the cooling outer cavity 37 through the infusion rotating tube 42, the infusion fixed tube 41, the inner fixed tube 47, the sliding tube 410, and the insertion tube 412, and the coolant inside the cooling outer cavity 37 can be transported to the cooling inner cavity 36 through the inner joint 39 and the outer joint 310. Furthermore, the coolant inside the cooling outer cavity 37 and the cooling inner cavity 36 can cool down the outer shaping mold 18 and the inner shaping mold 34, thereby cooling and shaping the automotive interior trim panel inside the mold cavity 35. After cooling and shaping the automotive interior trim panel inside the mold cavity 35, rotate the driving roller 3 and the demolding roller 5 again, so that the driving roller 3 can rotate the shaped outer shaping mold 18 and the inner shaping mold 34 to the demolding roller 5. When the position sensors 311 on the feeding die base 33 and the demolding base 53 detect each other's positions, stop the rotation of the driving roller 3 and the demolding roller 5. At this time, the outer shaping mold 18 presses on the demolding base 53,So that the outer shaping die 18 can be fitted to the demolding seat 53. When the outer shaping die 18 presses against the demolding seat 53, the insertion tube 412 is inserted into the interior of the air supply pressure valve 54 and opens it. At this time, the air pump 13 can deliver gas to the mold cavity 35 through the air supply transfer tube 52, the air supply fixed tube 51, the inner fixed tube 47, the sliding tube 410, and the insertion tube 412, so that the gas is poured into the gap between the automotive interior trim panel and the inner wall of the mold cavity 35, enabling the automotive interior trim panel to be separated from the inner walls of the outer shaping die 18 and the inner shaping die 34, and demolding the automotive interior trim panel from the outer shaping die 18 and the inner shaping die 34. Then, the outer shaping die 18 is rotated above the conveyor belt 16 by the driving roller 3, and then the rotation motor 313 is reversed so that the L-shaped locking block 314 no longer fixes the outer shaping die 18 and the inner shaping die 34. At the same time, the electromagnetic suction plate 312 is powered off and no longer magnetically fixes the outer shaping die 18 and the inner shaping die 34, causing the outer shaping die 18 and the automotive interior trim panel inside it to fall onto the conveyor belt 16 together. The conveyor belt 16 continues to convey the outer shaping die 18 and the automotive interior trim panel to the right and out of the outside of the chassis 1, and they are sorted manually.,
