Multi-angle cooling device for 3D printing of false teeth

The utility model relates to the technical field of false tooth processing devices, in particular to a multi-angle cooling device for false tooth 3D printing, which comprises a processing box, sliding rods are symmetrically welded in the left and right of an inner cavity of the processing box, a hydraulic cylinder is embedded in one side of the processing box, and one end of the hydraulic cylinder is welded with a walking plate. The left side and the right side of the walking plate are connected with limiting sleeves through fixing rods, and an air inlet pipe is inserted into the upper end of the walking plate in a penetrating mode. The device has the advantages that through rotation of the main gear, the main gear drives the transmission gear ring to rotate, the transmission gear ring drives the air inlet pipe to rotate, and the air inlet pipe drives the air outlet pipe to rotate; cold air is introduced into the air inlet main pipe through the hose, flows through the air pipe connector, the air inlet pipe an
