[0023] When the constant pressure valve 5 is closed and the exhaust valve 7 and the outlet valve 11 are opened, starting the vacuum pump 9 will allow the air inside the stamping block 2 to be discharged through the exhaust pipe 6, the intake pipe 8 and the outlet pipe 10, so that the stamping block 2 is in a negative pressure state. At this time, under the action of the external air pressure, the stamped automobile precision parts will be tightly adsorbed on the outer surface of the suction cup 3, so that the parts can be lifted up as the movable mold 1 moves, thereby completing the demoulding. With the mutual cooperation of various mechanisms, the adsorption and demoulding of the automobile precision parts are realized, thereby preventing the traditional ejection demoulding from causing damage to the precision parts.

[0024] Among them, the top of the punch block 2 is fixedly sleeved with a fixed box 12, the fixed box 12 is movably sleeved with a slider 13, the top of the slider 13 is fixedly installed with a spring 14, and the other end of the spring 14 is fixedly installed at the top of the fixed box 12.

[0036] The working principle and use process of this utility model:

[0037] First, when stamping the precision parts of the automobile, the operator closes the outlet valve 11 and the pressure relief valve 27 and opens the constant pressure valve 5, the exhaust valve 7 and the blow valve 18, and then starts the vacuum pump 9, so that the external air enters the interior of the fixed box 12 through the constant pressure pipe 4, the exhaust pipe 6, the suction pipe 8, the outlet pipe 10, the connecting pipe 19 and the blow pipe 17, so that the slider 13 is subjected to a thrust, pushing the slider 13 with the extension rod 15 and the stopper 16 to move upward along the inner surface of the fixed box 12 and compress the spring 14. When the top of the stopper 16 contacts the bottom of the fixed box 12, the blow valve 18 and the vacuum pump 9 are closed and then the hydraulic cylinder 20 is started, so that the movable mold 1 moves downward with the stamping block 2 to complete the part. Stamping operation, then the operator opens the exhaust valve 7 and the outlet valve 11 and closes the constant pressure valve 5, and then starts the vacuum pump 9. At this time, the air inside the stamping block 2 will be discharged from the exhaust pipe 6, the suction pipe 8 and the outlet pipe 10, so that the stamping block 2 is in a negative pressure state, and then the parts are adsorbed, and finally the hydraulic cylinder 20 is started to make the movable mold 1 move up with the stamping block 2 to complete the demoulding. After the demoulding is completed, the operator closes the vacuum pump 9 and opens the constant pressure valve 5, so that the air pressure inside the stamping block 2 returns to normal, and then the operator can remove the parts. With the mutual cooperation of various mechanisms, the adsorption demoulding of automotive precision parts is realized, thereby preventing the use of traditional ejection demoulding and causing unnecessary damage to automotive precision parts.

[0038] After the stamping is completed, the operator opens the pressure relief valve 27 to restore the air pressure inside the fixed box 12 to normal. At this time, under the restoring action of the spring 14, the slider 13 will move downward along the inner surface of the fixed box 12 with the stopper 16 through the extension rod 15, so that the bottom end of the stopper 16 and the inner surface of the stamping block 2 are tightly fitted, thereby preventing external dust and impurities from entering the interior of the stamping block 2 through the suction cup 3, thereby protecting the stamping block 2.
