Summary:PURPOSE:To remove effectively thin flashes and resin dregs, by a method wherein at the time when a main body of a cleaner enters into or retreats from space between a pair of molds, a driving mechanism is operated, a brush supporting frame is rocked, the whole surface of a mold surface is brushed and dust is sucked and removed by a dust sucking part. CONSTITUTION:When an unloader enters into a space between a top and bottom molds, a vacuum mechanism communicating with a dust sucking part 50 operates and at the same time an air cylinder 22 and motor 39 begin to operate in a cleaner. Since the air cylinder 22 presses a brush 10, which has been separated from a mold surface by a spring, against the mold surface by opening a brush supporting frame 12, the resin left behind on the mold is scraped off by scraping out the mold surface with the brush 10. A driving shaft 30 is turned by operating a motor 39, a cam follower 42 is rocked according to a groove cam 40, the brush supporting frame 12 is rocked laterally by being guided by a right and left guide 14, the whole sphere of the mold surface is cleaned and the peeled off resin dregs are removed by the dust sucking part 50.
