Rapid demolding mechanism

The utility model discloses a quick demolding mechanism which comprises a fixed table, a mold, a demolding assembly and a cleaning assembly are fixedly mounted on the upper surface of the fixed table, a vacuum pump is arranged on the upper surface of the demolding assembly, and a suction cup is arranged on the upper surface of the demolding assembly. The cleaning assembly on the fixing table runs to scrape off resin products dripping on the surface of the mold, the demolding assembly runs to drive the vacuum pump and the suction cup to move downwards into the mold, and the suction cup presses and adsorbs the formed resin products in the mold; and then air in the suction cup is pumped out through operation of the vacuum pump, the suction cup is tightly adsorbed to the formed resin product, finally, the vacuum pump and the suction cup are driven to move upwards through operation of the demolding assembly again, and the formed resin product is driven by the suction cup to be demolded from the interior of the mol
