发明名称 Injection blow molding with improved cooling
摘要 This invention cools the blowing mold and the plastic article blown therein to shorten the time that a core rod must remain at a blowing station of a blow molding machine for making plastic articles. The cooling is performed by conditioned air that is dried to lower its dew point. An air curtain is used to prevent other air from contacting with and depositing moisture on the mold. In order to take advantage of the shorter time at the blowing station, an auxiliary injection device is used to also shorten the time required for the injection operation; and auxiliary cooling is supplied to the core rod at the stripper station.
