Abstract

Un aparato para termoformar artículos de plástico, comprendiendo: una boquilla (4) de extrusión de lámina para extrudir una lámina de material termoplástico; una rueda formadora (6) para recibir la lámina extrudida desde la boquilla de extrusión y compuesta por una pluralidad de facetas (8) de molde, conteniendo cada una de dichas facetas (8) de molde al menos una cavidad (21) de molde; medios para hacer girar dicha rueda formadora (6) alrededor de un eje horizontal de modo que cada una de dichas facetas (8) de molde es movida a través de sectores (9, 10) dedicados a formar dicha lámina en dichos artículos y a expulsar dichos artículos; un núcleo (34) de ayuda de termoformación, en el que dicho núcleo (34) de ayuda está dispuesto sobre dicho sector (9) de formación de dicha rueda formadora (6); medios para sincronizar el movimiento de dicho núcleo (34) de ayuda de termoformación con el movimiento de dichas facetas (8) de molde cuando gira dicha rueda formadora (6); medios para accionardicho núcleo (34) de ayuda de termoformación al interior de dicha lámina termoplástica y dicha cavidad (21) de molde; medios para evacuación del aire desde el inte- rior de dicha cavidad (21) de molde, formando de tal modo un artículo asociado con cada una de dichas cavidades (21) de molde, en el que porciones de dicha lámina permanecen sin formar; estando compuestas dichas facetas (8) de mol- de por una sección superior estática (18) de faceta de molde y una sección inferior dinámica (17) de faceta de molde; conteniendo dicha sección inferior dinámica (17) de faceta de molde dicha cavidad (21) de molde; soportando dichas secciones estática y dinámica (18, 17) de faceta de molde circuitos para hacer circular un medio de control de temperatura y el vacío; una placa de leva fija (38) que contiene una pista de leva; y un conjunto (25, 26) de barra de guía que incluye medios (26) teniendo un seguidor de leva que sigue dicha pista de leva en dicha placa de leva fija (38) durante la rotaciónde dicha rueda formadora (6) para accionar y guiar el movimiento de dicha sección inferior dinámica (17) de faceta de molde hacia dicho eje de la rueda formadora cuando el molde entra en el sector (10) dedicado a expulsar dichos artículos.
