Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] See also Figure 1-4 As shown, an automatic production line for automobile foam steering wheels is provided, comprising a production line shed 1, a hanging conveyor line 2, a gripping tool 3, an industrial manipulator 4, and a clamping machine 5. Six clamping machines 5 are distributed in the production line shed 1, and an industrial manipulator 4 is configured on one side of each clamping machine 5. The end of each industrial manipulator 4 is not limited to being equipped with an injection molding gun head. A hanging conveyor line 2 is installed on the top of the production line shed 1, and a gripping tool 3 is configured on the hanging conveyor line 2. By moving the industrial robot 4 between the clamping machine 5 and the grabbing tool 3 at the corresponding position, and combining with the lifting conveyor line 2 to drive the grabbing tool 3 to move to the corresponding work station, the automation level of automobile foam steering wheel production is greatly improved, with high efficiency and large output.

[0020] The clamping machine 5 includes a machine frame 510, a foaming lower mold 520, a foaming upper mold 530, an oil cylinder 560, a high-pressure air pump 570 and a positioning hole plate 580. The foaming lower mold 520 is installed on the top of the machine frame 510, and the foaming lower mold 520 and the foaming upper mold 530 form a steering wheel foaming mold; When the industrial robot 4 places the steering wheel keel on the foaming lower mold 520, the oil cylinder 560 is in a contracted state, driving the rectangular frame 550 connected by the L-shaped piece 554 and its connected parts to rotate to one side, so that the foaming upper mold 530 located on the carrier 551 rotates sideways and covers the foaming lower mold 520. The above-mentioned reverse operation method is used to complete the separation of the foaming upper mold 530 and the foaming lower mold 520, realizing automatic mold closing and opening.

[0021] The air hole grooves 522 on the foaming lower mold 520 are connected to the output port of the high-pressure air pump 570 via an air guide tube 572. The air hole grooves 522 and the short columns 532 on the foaming upper mold 530 are elastically inserted into each other. The inner ends of the short columns 532 are elastically connected to the corresponding circular grooves 531 on the foaming upper mold 530 via springs. The air guide tubes 572 at the two ports of the high-pressure air pump 570 are respectively located in the corresponding ice cube storage boxes 571. When the upper foaming mold 530 and the lower foaming mold 520 are put together, the short column 532 is elastically inserted into the pore groove 522 to block the pore groove 522. When the foaming agent output device 540 injects the foaming agent through the foaming inlet hole 521, the foaming agent needs to be cooled from a high-temperature molten state to a solidified state. Therefore, the high-pressure air pump 570 gradually increases the pressure to output low-temperature gas, which enters the air hole groove 522 through the air guide pipe 572. The air pressure in the air hole groove 522 pushes the bottom end of the short column 532 into a suspended state, allowing the low-temperature air to diffuse into the steering wheel foaming mold, achieving cold blowing and cooling, and accelerating the solidification of the foaming agent. When the upper foaming mold 530 and the lower foaming mold 520 are gradually separated, high-pressure gas is blown into the steering wheel foaming mold, which can not only speed up demoulding but also blow away impurities on the inner wall of the mold, ensuring the cleanliness of the inner wall of the mold.

[0022] The middle of the foaming lower mold 520 is provided with a foaming introduction hole 521 connected to the output port of the foaming agent output device 540 located on one side of the machine frame 510, so as to facilitate the injection of molten foaming agent into the mold.

[0023] The foaming upper mold 530 is installed on one side of the carrier 551 , and the carrier 551 is installed on one side of the rectangular frame 550 , so as to be used for the installation and connection of the foaming upper mold 530 through the carrier 551 .

[0024] Furthermore, U-shaped pieces 552 are installed at both ends of the top of one side of the rectangular frame 550 , and U-shaped pieces 555 are installed at both ends of the bottom of one side of the rectangular frame 550 .

[0025] Furthermore, a cylinder 553 is installed at the port on one side of the U-shaped part 552, and the U-shaped part 552 is connected to the positioning hole plate 580 through the output end of the cylinder 553, and the U-shaped part 2 555 is rotatably connected to the pin hole seat 556 located at the rear end of the machine frame 510 through a rotating shaft.

[0026] Furthermore, L-shaped pieces 554 are installed at the bottom ends of both sides of the rectangular frame 550 , and one end of the L-shaped piece 554 is rotatably connected to the output end of the oil cylinder 560 located at the corresponding position of the machine frame 510 .

[0027] Furthermore, the tube portion between the two ends of the air guide tube 572 is distributed in a serpentine shape in the ice storage box 571, so as to achieve heat exchange of the gas output or input by the high-pressure air pump 570 to a low temperature.

[0028] When the present invention is in use, the industrial manipulator 4 moves between the clamping machine 5 and the grasping tool 3 at the corresponding position, and in combination with the lifting conveyor line 2, drives the grasping tool 3 to move to the corresponding work station. The end of the industrial manipulator is not limited to being configured with an injection molding gun head, but can complete production tasks such as spraying release agent, spraying paint in the mold, drying paint and grasping, thereby greatly improving the automation level of automobile foam steering wheel production, with high efficiency and large output. When the industrial robot 4 places the steering wheel keel on the foaming lower mold 520, the oil cylinder 560 is in a contracted state, driving the rectangular frame 550 connected by the L-shaped piece 554 and its connected parts to rotate to one side, so that the foaming upper mold 530 located on the carrier 551 rotates sideways together and covers the foaming lower mold 520. The above reverse operation method is used to complete the separation of the foaming upper mold 530 and the foaming lower mold 520, realizing automatic mold closing and opening; When the upper foaming mold 530 and the lower foaming mold 520 are put together, the short column 532 is elastically inserted into the pore groove 522 to block the pore groove 522. When the foaming agent output device 540 injects the foaming agent through the foaming inlet hole 521, the foaming agent needs to be cooled from a high-temperature molten state to a solidified state. Therefore, the high-pressure air pump 570 gradually increases the pressure to output low-temperature gas, which enters the air hole groove 522 through the air guide pipe 572. The air pressure in the air hole groove 522 pushes the bottom end of the short column 532 into a suspended state, allowing the low-temperature air to diffuse into the steering wheel foaming mold, achieving cold blowing and cooling, and accelerating the solidification of the foaming agent. When the upper foaming mold 530 and the lower foaming mold 520 are gradually separated, high-pressure gas is blown into the steering wheel foaming mold, which can not only speed up demoulding but also blow away impurities on the inner wall of the mold, ensuring the cleanliness of the inner wall of the mold.
