Abstract: A battery type mold assembly in which simple upwardly extending mold members having relief patterns on their major mold surfaces are pivotally mounted on a frame at the lower ends so as to be movable between a closed position in which a mold cavity is formed and an open position in which there is provided for the removal of a molded article therefrom. The assembly is characterized by the presence of carrier members which are, at least initially, adjustable relative to each other and the carrier members are pivotally connected to the mold members.
