<p>A method and apparatus for cleaning molds, particularly tire molds (16) using pellets of a frozen gas and a robotically controlled apparatus are disclosed. A heated mold (16) is conveyed into an insulated and sound-proof enclosure (34) where a robot arm with a nozzle (52) mounted on the robot arm directs frozen CO2 pellets against the mold surface to be cleaned. The mold (16) is rotated on a rotary table (40) to clean the entire mold surface. The mold (16) is then removed from the enclosure (34) on a conveyor (82). The preferred frozen gas is CO2 because it is non-abrasive to the tire mold surfaces and also cleans the microvents of the tire mold (16).</p> |
