PURPOSE:To avoid the occurrence of surface defect by taking out a molded object by means of blowing out again the air for taking out from the side of movable mold after the mold is opened. CONSTITUTION:The air for mold release is flown out from the air-blowing part 62 of the side of a stationary mold to a disk molded object after a prescribed coaling time is kept from the finish of injection and immediately before mold-opening. Almost simultaneously with said air-blowing or with a little time lag behind said air-flowing, the air for taking out is blown out also from the air-blowing part 67 of the side of a movable mold to a disk molded object. When the opening of the mold is advanced and finished, the air for taking out is again blown out from the side of movable mold in taking out of a product, and the molded object is ejected with an ejector 50. Consequently the occurrence of the surface defect due to insufficient mold release may be avoided. |
