<p>Injection molding method and apparatus for ejecting a molded plastic article (26) from a mold. A lifting structure and/or step is provided with a lifting portion (201) which is configured to contact at least one half of an end of the molded plastic article (26) along a line substantially perpendicular to the lifting direction. Since the molded plastic article (201) is lifted by its end, the article (26) does not have to be solidified at its interior, thus allowing earlier removal of the article from the mold (100), reducing cycle time. A tapered surface (263) forms an acute angle with respect to the lifting portion (201) to form a tight seal with the mold, preventing leakage. Preferably, the neck ring (118a, 118b) engages only an outer circumferential portion of the molded plastic article during a majority of a mold opening stroke.</p> |
