  • Patent number: 4205950
    Abstract: Synthetic-resin articles are injection molded with at least one stationary mold cavity on the stationary mold plate being alternately aligned with carriers on the mold-closure plate so that each article is entrainable by this plate into a working station in which, for example, it can be cooled. During the injection molding of one article in the mold cavity defined between the stationary mold half and one of these carriers, a previously molded article is solidified on the other carrier in a working station offset from the stationary mold half. The newly injected mass is retained in the mold cavity only until the surface regions have cooled and set and the plate is then laterally shifted perpendicular to the mold closing direction to carry the article having the set surface regions and still fluid core into a working station while the other carrier, from which the cooled article has been ejected, is aligned with the stationary mold cavity.
