Post-mold cooling of injection molded plastic articles such as preforms is achieved by transferring the articles directly from the mold cavities (42) onto cooling cores (62) carried by a take-out plate (60). The molded articles are supported on the cooling cores (62) until they become sufficiently frozen that they can be stripped from the cores (62).
