Grinding tool pressing device

The utility model belongs to the technical field of pressing, and particularly relates to a grinding tool pressing device which comprises a bearing plate serving as a connecting base, connecting rods are connected to the four end corners of the top of the bearing plate, a mounting base is connected to the top ends of the connecting rods, a demolding component comprises driving motors symmetrically mounted at the top of the mounting base, and the output ends of the driving motors are connected with threaded lead screws. The bottom end of the threaded lead screw extends to the position below the mounting base and is in threaded fit with the threaded base, the die pressing component is arranged on the bearing plate, and the driving motor works to drive the threaded lead screw to rotate. The upper mold connecting plate does linear reciprocating motion along the threaded lead screw, so that the height position of the upper mold is driven to change, and demolding operation of the upper mold and the lower mold is fa
