[0034] Reference Figure 1-Figure 5In a preferred embodiment, the adsorption demoulding mechanism adsorption box 3 is installed at the bottom of the demoulding platform 1, and a connecting head 4 is installed on the left side of the adsorption box 3. The adsorption tube 5 is fixedly connected to both sides of the top of the front side of the adsorption box 3, and the other end of the adsorption tube 5 is fixedly connected to the surface of the demoulding seat 2. Both sides of the top of the adsorption box 3 are fixedly connected with connecting pipes 6. The adsorption cavity 7 is opened on both sides of the interior of the demoulding platform 1. The adsorption cavity 7 is connected with the connecting pipe 6. The rear side of the adsorption cavity 7 is movably connected with a slide bar 8. Both sides of the interior of the demoulding platform 1 are provided with adsorption holes 9 connected with the adsorption cavity 7. The adsorption lifting mechanism is arranged on both sides of the interior of the demoulding seat 2. Since the adsorption cavity 7 is connected with the adsorption box 3 through the connecting pipe 6, and the demoulding seat 2 and the adsorption box 3 are connected through the adsorption tube 5, and the interior of the demoulding platform 1 is provided with adsorption holes 9 connected with the adsorption cavity 7, the adsorption box 3 is connected with the external exhaust equipment through the connecting head 4, and then the outside is held and placed on the top of the demoulding platform 1. The demoulding seat 2 is held and placed on the top of the upper mold of the external mold. At this time, the adsorption box 3 is in a negative pressure state due to the air suction of the external vacuum equipment, so that the demoulding seat 2 and the demoulding platform 1 respectively adsorb and position the upper mold and the lower mold of the external mold. Subsequently, the upper mold and the lower mold can be separated by lifting the demoulding seat 2 to perform the workpiece removal and demoulding operation.

[0038] Specifically, the working process or working principle of the demoulding device for automobile interior plastic parts is as follows: when in use, the handheld movable box 21 is installed into the adsorption box 3 through the movable port 20, and then the adsorption box 3 is connected to the external exhaust device through the connector 4. Subsequently, the mold to be separated and demoulded from the workpiece is placed on the top of the demoulding table 1, and the handheld demoulding seat 2 is placed on the top of the upper mold of the external mold, and then the handheld pull-out frame 18 is pulled by the pull-out rod 17 to move the front side of the slide bar 8, so that the connecting pipe 6 is connected to the adsorption chamber 7. At this time, the interior of the adsorption box 3 is affected by the exhaust of the external exhaust device and is in a negative pressure state. In the pressure state, the adsorption chamber 7 and the adsorption hole 9 generate suction through the connecting pipe 6, and the lower mold of the external mold on the top of the demolding table 1 is adsorbed and positioned. At this time, the adsorption box 3 generates suction through the adsorption tube 5 to the adsorption groove 10 and the lifting hole 11, and the upper mold of the external mold at the bottom of the demolding seat 2 is adsorbed and positioned. At the same time, when the filter cylinder 19 adsorbs the external mold to the adsorption hole 9 and the lifting hole 11, the impurities entering the adsorption box 3 are filtered. The impurities filtered and blocked by the filter cylinder 19 fall into the inside of the movable box 21, which is convenient for the user to clean and remove impurities in a unified manner later. After that, the lifting handle 12 is held and driven to move the demoulding seat 2 upwards, so that the upper mold and the lower mold of the external mold can be separated, and the separated upper mold is placed on one side of the top of the demoulding table 1. After the upper and lower molds are separated, the lifting handle 12 is rotated to separate from the clamping seat 15, and then the lifting handle 12 is pulled upwards to drive the partition bar 13 to move upwards through the connecting column 14, and the air is cut off between the adsorption groove 10 and the adsorption tube 5, so that the demoulding seat 2 and the upper mold of the external mold can be separated. In this process, the rotating seat 23 rotates inside the rotating groove 22 to connect the connecting column 14. The column 14 and the spacer bar 13 are rotated and connected, and then the demolding seat 2 is placed on the top of the workpiece inside the lower mold of the external mold. The lifting handle 12 is moved downward to push the spacer bar 13 into the bottom of the adsorption groove 10 through the connecting column 14, and the lifting handle 12 is rotated to enter the inside of the clamping seat 15, so that the adsorption box 3 is connected with the adsorption groove 10 and the lifting hole 11 through the adsorption tube 5 again, so that the lifting hole 11 generates suction to adsorb and position the workpiece inside the lower mold of the external mold, and then the demolding seat 2 is lifted upward to perform the demolding and separation operation between the workpiece and the lower mold of the external mold.
