Abstract
(DE) Die Erfindung betrifft eine Formgebungseinrichtung (3) zur Formgebung und Abkühlung von Gegenständen aus einer Kunststoffschmelze, wobei diese einem Extruder nachordenbar ist. Die Formgebungseinrichtung (3) umfasst eine in einem Eintrittsbereich (19) angeordneten Einlassöffnung (20) für die Kunststoffschmelze, zumindest einen sich hin in Richtung eines Austrittsbereichs (22) erstreckenden Kanal (21) mit diesen begrenzenden Kanal Wandungen (23, 24), und zumindest eine den Kanalwandungen (23, 24) zugeordnete Kühlvorrichtung (27). Innerhalb des Kanals (21) ist in dem, dem Eintrittsbereich (19) unmittelbar benachbarten Bereich eine zusätzliche Kühlvorrichtung (28) für die hindurchzutuhrende Kunststoffschmelze angeordnet.
(EN) The invention relates to a shaping device (3) for shaping and cooling articles produced from a plastic melt, whereby said device can be arranged downstream of an extruder. The shaping device (3) comprises, arranged in an entry area (19), an inlet opening (20) for the plastic melt, at least one channel (21) extending in the direction of an outlet area (22) and having channel walls (23, 24) delimiting the same, and at least one cooling device (27) associated with the channel walls (23, 24). An additional cooling device (28) for the plastic melt to be passed through is provided inside the channel (21) in the area directly adjacent to the inlet area (19).
(FR) L'invention concerne un dispositif de modelage (3) permettant de modeler et de refroidir des articles en matière synthétique fondue, ledit dispositif pouvant être placé après une extrudeuse. Ledit dispositif de modelage (3) comprend un orifice d'entrée (20) disposé dans une partie entrée (19) destiné à la matière synthétique fondue, au moins un canal (21) s'étendant dans le sens d'une partie sortie (22) comprenant au moins des parois de canaux (23, 24) limitant le canal, et au moins un dispositif de refroidissement (27) ajouté aux parois de canaux (23, 24). A l'intérieur du canal (21), un dispositif de refroidissement (21) supplémentaire est placé dans la partie entrée (19) de manière directement adjacente, ce dernier étant destiné à la matière synthétique fondue introduite.
