Abstract

El dispositivo se compone de varillas de expulsión y de mantenimiento (14) cuyas extremidades (15) nervadas se alojan cada una en una estructura en forma de alvéolo (16) con el fondo (22) con nervios complementarios y cuya superficie lateral está prolongada por estructuras de refuerzo (17) en forma de nervios longitudinales en el sentido de la fuerza de extracción de las calas moldeantes (12) de su alojamiento. Este mantenimiento permite extraer las calas moldeantes (12) llevadas por varillas de extracción (13). Esta invención interesa a los fabricantes de moldes en particular de moldes por inyección para fabricar objetos en materia plástica con estructura en caja.
