The magnet mold pressing device comprises a rack, a bottom mold, a hydraulic rod and a water tank, the bottom mold is installed on the outer wall of the rack, the hydraulic rod is installed at the top of the rack, the bottom of the hydraulic rod extends out of the bottom of the rack, the water tank is installed on the back face of the bottom mold, and a female mold is arranged at the top of the bottom mold; and an electric telescopic rod is mounted on the inner bottom wall of the bottom die. By installing the vibration plate and the impact ball, die taking can be conveniently conducted, the driving motor drives the rotating rod to rotate, the rotating rod drives the impact rod to rotate, the impact rod drives the impact ball to rotate, and the impact ball rotates to impact the vibration plate, so that vibration is received between the female die and the magnet, the magnet and the female die are separated, and bonding is prevented; and then the electric telescopic rod is started, the electric telescopic rod drives the supporting plate to rise, the supporting plate drives the female die to stretch out of the bottom die, and the function of conveniently taking the die is achieved.
