[0013] A method for using a shaping tool for an automobile interior trim panel comprises the following steps: The first step is to place the car interior panel inside the external shaping mold, and then place the external shaping mold on the conveyor belt, and use an electric clamping frame to limit and fix the external shaping mold so that the conveyor belt can transport the external shaping mold and the car interior panel from left to right; In the second step, when the outer shaping mold moves to the right below the inner shaping mold, the conveyor belt stops rotating, and then the electric clamping frame releases the outer shaping mold and no longer clamps and fixes it. At this time, the outer shaping mold can be adsorbed upward onto the inner shaping mold through the electromagnetic suction plates on the outer shaping mold and the inner shaping mold. At this time, the outer shaping mold is separated 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, and then the rotating motor is started to drive the L-shaped locking block to rotate, so that the L-shaped locking block can be movably engaged with the L-shaped locking groove, so that the outer shaping mold can be fixed on the inner shaping mold, so that the outer shaping mold and the inner shaping mold are combined to form a mold cavity; The third step is to rotate the driving roller counterclockwise, and through the meshing of the driving gear ring with the driven gear rings on both sides thereof, the cooling roller and the demoulding 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, the driving roller and the cooling roller are stopped from rotating. At this time, the outer shaping die is located inside the cooling die base, and the cannula is inserted into the coolant pressure valve and opened. Then the cooling pump can transport the coolant to the cooling outer cavity through the infusion transfer tube, the infusion fixed tube, the inner fixed tube, the sliding tube and the cannula. The coolant inside the cooling outer cavity can be transported to the cooling inner cavity through the inner joint and the outer joint, and the outer shaping die and the inner shaping die are cooled, so that the automobile interior trim panel inside the cavity can be cooled and shaped. In the fourth step, after the automobile interior trim panel inside the mold cavity is cooled and shaped, the driving roller is rotated again so that the driving roller can rotate the shaped external shaping mold and the internal shaping mold to the demoulding roller. When the position sensors on the feeding mold base and the demoulding base detect each other's positions, the driving roller and the demoulding roller are stopped. At this time, the external shaping mold is located inside the demoulding base, and the cannula is inserted into the inside of the gas pressure valve and opened. Then the air pump can transport the gas to the inside of the mold cavity through the gas transfer pipe, the gas fixed pipe, the internal fixed pipe, the sliding pipe and the cannula, so as to inject the gas into the automobile. The gap between the car interior trim panel and the mold cavity can be formed, so that the car interior trim panel can be separated from the inner walls of the outer shaping mold and the inner shaping mold, and then the outer shaping mold is rotated to the top of the conveyor belt by the driving roller, and then the motor is reversed so that the L-shaped lock block no longer fixes the outer shaping mold and the inner shaping mold, and at the same time, the electromagnetic suction plate is powered off and the outer shaping mold and the inner shaping mold are no longer magnetically fixed, so that the outer shaping mold and the car interior trim panel inside it fall on the conveyor belt together, and the conveyor belt continues to transport the outer shaping mold and the car interior trim panel to the right and move them to the outside of the chassis for manual sorting.

[0014] (III) Beneficial effects The present invention provides a shaping tool and method for automobile interior trim panels, which has the following beneficial effects: 1. When the outer shaping mold moves to the bottom of the inner shaping mold, the clamping frame releases the outer shaping mold and no longer clamps it. The outer shaping mold can be adsorbed upward onto the inner shaping mold through the electromagnetic suction plates on the outer shaping mold and the inner shaping mold, and the outer joint is inserted into the inner joint, so that the cooling inner cavity and the cooling outer cavity are connected. Then the rotating motor is started to drive the L-shaped locking block to rotate ninety degrees, so that the L-shaped locking block can be movably engaged with the L-shaped locking groove, so that the outer shaping mold can be fixed on the inner shaping mold, so that the outer shaping mold and the inner shaping mold are combined to form a mold cavity.

[0015] 2. When the position sensors on the feeding die base and the cooling die base detect each other's positions, the driving roller and the cooling roller stop rotating, the external shaping die is located inside the cooling die base, and the cannula is inserted into the coolant pressure valve and opened. The cooling pump can transport the coolant to the cooling outer cavity through the infusion transfer tube, the infusion fixed tube, the inner fixed tube, the sliding tube and the cannula, and the coolant inside the cooling outer cavity can be transported to the cooling inner cavity through the inner joint and the outer joint, and then the coolant inside the cooling outer cavity and the cooling inner cavity can be used to cool the external shaping die and the inner shaping die, so that the automobile interior trim panel inside the cavity can be cooled and shaped.

[0016] 3. When the position sensors on the feeding mold base and the demoulding base detect each other's positions, the driving roller and the demoulding roller are stopped, and the insert tube is inserted into the interior of the gas pressure valve and opened. At this time, the air pump can transport gas to the mold cavity through the gas transfer pipe, the gas fixed pipe, the inner fixed pipe, the sliding pipe and the insert tube, so that the gas is poured into the gap between the automobile interior trim panel and the inner wall of the mold cavity, which can separate the automobile interior trim panel from the inner walls of the outer shaping mold and the inner shaping mold, so that the automobile interior trim panel is demoulded from the outer shaping mold and the inner shaping mold.

When the position sensors 311 on the feeding mold base 33 and the demolding base 53 detect each other's positions, the driving roller 3 and the demolding roller 5 are stopped. At this time, the outer shaping mold 18 is located inside the demolding base 53, and the cannula 412 is inserted into the inside of the gas supply pressure valve 54 and opened. Then, the air pump 13 can deliver gas to the inside of the mold cavity 35 through the gas supply transfer pipe 52, the gas supply fixed pipe 51, the inner fixed pipe 47, the slide pipe 410 and the cannula 412, so as to fill the gas. The outer shaping mold 18 is then rotated to the top of the conveyor belt 16 by the driving roller 3, and then the motor 313 is reversed so that the L-shaped locking block 314 no longer fixes the outer shaping mold 18 and the inner shaping mold 34, and at the same time, the electromagnetic suction plate 312 is powered off and the outer shaping mold 18 and the inner shaping mold 34 are no longer magnetically fixed, so that the outer shaping mold 18 and the inner shaping mold 34 fall on the conveyor belt 16 together with the inner decorative panel of the automobile. The conveyor belt 16 continues to transport the outer shaping mold 18 and the automobile decorative panel to the right and moves them to the outside of the chassis 1 for manual sorting.

[0030] The working principle and use process of the present invention are as follows: by connecting the conveyor belt 16 with the external driving device, the conveyor belt 16 can be driven to rotate clockwise, and then the automobile interior trim panel is first placed inside the external shaping mold 18, and then the external shaping mold 18 is placed on the conveyor belt 16, and the external shaping mold 18 is limited and fixed on the conveyor belt 16 by the electric clamping frame 17, so that the conveyor belt 16 can drive the external shaping mold 18 and the automobile interior trim panel to move to the right, and at the same time, the driving motor 11 can drive the driving roller 3 to rotate counterclockwise, and the driving roller 3 can drive the cooling roller 4 and the demoulding roller 5 to rotate clockwise through the engagement between the driving gear ring 21 and the driven gear ring 22. When the external shaping mold 18 moves to the bottom of the internal shaping mold 34, the driving roller 3 and the transmission are stopped. The conveyor belt 16 rotates, and then the clamping frame 17 releases the outer shaping mold 18 and no longer clamps it. At this time, the electromagnetic suction plates 312 on the outer shaping mold 18 and the inner shaping mold 34 can adsorb the outer shaping mold 18 upward onto the inner shaping mold 34. At the same time, the outer shaping mold 18 is separated from the conveyor belt 16, and the outer joint 310 is inserted into the inner joint 39, so that the cooling inner cavity 36 and the cooling outer cavity 37 are connected, and then the rotating motor 313 is started to drive the L-shaped locking block 314 to rotate ninety degrees, so that the L-shaped locking block 314 can be movably engaged with the L-shaped locking groove 315, so that the outer shaping mold 18 can be fixed on the inner shaping mold 34, so that the outer shaping mold 18 and the inner shaping mold 34 are combined to form a mold cavity 35, and then 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 the positions of each other, the driving roller 3 and the cooling roller 4 are stopped from rotating. At this time, the external shaping die 18 is located inside the cooling die base 46, and the external shaping die 18 squeezes the cooling die base 46, so that the T-shaped limiting slider 45 moves inside the T-shaped limiting slide groove 43, so that the external shaping die 18 can fit with the cooling die base 46. When the external shaping die 18 squeezes the cooling die base 46, the cannula 412 is inserted into the interior of 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 transfer tube 42, the infusion fixed tube 41, the inner fixed tube 47, the slide tube 410 and the cannula 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, and then the coolant inside the cooling outer cavity 37 and the cooling inner cavity 36 can cool the outer shaping mold 18 and the inner shaping mold 34, so that the automobile interior trim panel inside the mold cavity 35 can be cooled and shaped. After the automobile interior trim panel inside the mold cavity 35 is cooled and shaped, the driving roller 3 and the demolding roller 5 are rotated 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 mold base 33 and the demolding base 53 detect each other's positions, the driving roller 3 and the demolding roller 5 are stopped. At this time, the outer shaping mold 18 squeezes the demolding base 53.In order to make the outer shaping mold 18 fit with the demoulding seat 53, when the outer shaping mold 18 squeezes the demoulding seat 53, the insert 412 is inserted into the inside of the gas supply pressure valve 54 and opens it. At this time, the air pump 13 can transport gas to the mold cavity 35 through the gas supply transfer pipe 52, the inner fixed pipe 47 of the gas supply fixed pipe 51, the slide pipe 410 and the insert 412, so that the gas is poured into the gap between the automobile interior panel and the inner wall of the mold cavity 35, and the automobile interior panel can be separated from the outer shaping mold 18 and the inner wall of the inner shaping mold 34, so that the automobile interior panel and the outer shaping mold 18 and the inner shaping mold 34 are demoulded, and then the outer shaping mold 18 is rotated to the top of the conveyor belt 16 by the driving roller 3, and then the motor 313 is reversed to make the L-shaped lock block 314 no longer fix the outer shaping mold 18 and the inner shaping mold 34, and at the same time, the electromagnetic suction plate 312 is powered off and no longer magnetically fixes the outer shaping mold 18 and the inner shaping mold 34, so that the outer shaping mold 18 and the car interior panel inside it fall on the conveyor belt 16 together, and the conveyor belt 16 continues to transport the outer shaping mold 18 and the car interior panel to the right and move them out to the outside of the chassis 1, and they are sorted manually.
