PURPOSE: To contrive to take away resin burrs effectively by providing the air-blowing out device having the blowing port opening to the mold in which compressed air is fed to the platen supporting the mold.
CONSTITUTION: After a molded object has been taken out and the resin burr generated in resin sealing on a mold surface has been separated from the surface of a top force and a bottom force by brushing, compressed air is fed from an air-feeding tube 38, while a blowing out tube 34 is locked by operating a cylinder device 25, and then the compressed air is blown out toward the mold from the blowing port 35, thereby removing the resin burr. Then, since an air blowing out device 31 is provided on an upper platen 21, even when the upper and lower platens re relatively moved, the interference of the air-blowing out device 31 with the upper and lower platens may be avoided. Therefore, since the blowing out device 35 may be brought closer to the top and bottom forces, the pressurized air blown out from the blowing port 35 and applied to the top force and the bottom force may be heightened that much. Accordingly, the resin burr on the mold-surface is blown off violently, and the resin burr is removed effectively.
