Precast concrete production system and demolding mechanism thereof

The utility model discloses a precast concrete production system and a demolding mechanism thereof. The demolding mechanism comprises a turnover bracket, a drive mechanism and a mounting base, wherein the drive mechanism is arranged below the turnover bracket for driving the turnover bracket to rotate; a first hinge hole is formed in the mounting base; a support frame and a connecting rod are arranged on the turnover bracket; one end of the connecting rod is hinged to the mounting base at the first hinge hole; the other end is fixedly connected with the support frame; the position of the first hinge hole is higher than the support frame. The mounting base is fixed on the ground of a factory building when the demolding mechanism is applied, and the frame and a drive roller of the precast concrete production system are kept steady basically. The support frame still can be arranged at the height matched with the drive roller by forming the first hinge hole at the position higher than the support frame by the dem
