PROBLEM TO BE SOLVED: To clean a mold inexpensively by a method in which a cleaning jet containing dry ice pellets and a carrier medium is generated, and the nozzle of a jetting device is moved to direct the jet to the surface of an inner wall. SOLUTION: A jetting device 4 having at least one jet nozzle 8 is arranged in a chamber 9, and a cleaning jet 7 containing dry ice pellets and a carrier medium is ejected to at least a part of an inner wall 14 through a jet nozzle 8. When a partial mold 1 is moved along an axis A, a casing 3 and a jetting device 4 are introduced between partial molds 1, 2. The ends 5, 6 of the casing 3 are made to collide with the partial molds 1, 2. The jet is ejected to the inner walls 14 of the partial molds 1, 2. For this purpose, the jetting device 4 is moved appropriately by a conveyer 16. |
