Post-mold cooling method and apparatus with cyclone cooling effect

The invention relates to a post-mold cooling method and an apparatus with cyclone cooling effect. The post-molding cooling apparatus directs a stream of cooling fluid (50) against a concave interior surface of a molded article (10) to cool the molded article. The apparatus includes an outlet (40, 100, 140, 150) positioned to direct the stream of cooling fluid (50) into an open end of the molded article (10). The interior surface of the molded article (10) is concave. The outlet (40, 100, 140, 150) is configured to direct the stream of cooling fluid (50) in a helical direction such that at least a portion of the concave interior surface of the molded article (10) acts as a curved surface relative to a direction of flow of the stream of cooling fluid to create turbulent flow of the stream of cooling fluid against the concave interior surface of the molded article along a length of the concave interior surface from the open end of the molded article toward a closed end of the molded article. 本发明涉及种具有旋风冷却效果的模制后冷却
