Abstract

La presente invención se refiere a una unidad de desmoldeo para una cavidad similar a recipiente (10) de un componente moldeado por inyección en una manera que de una forma no surge ninguna separación en un lado inferior (16) del componente moldeado por inyección y al menos esta parte del lado inferior puede ser usada como una superficie sellante. Para este propósito, la unidad de desmoldeo tiene un elemento de desmoldeo interno movible (26), un lado frontal (42) el cual es usado para formar el lado inferior libre de rebabas (16). Con el fin de producir proyecciones proporcionadas en el lado de la cavidad (10), se proporcionan elementos de desmoldeo de proyecciones (32,34). Los elementos de desmoldeo de proyecciones pueden ser movidos en la dirección circunferencial por medio de un elemento de retención/liberación (30) durante el desmoldeo.
