Abstract
(DE)
Vorrichtung (1) zum Umformen von Kunststoffvorformlingen(10) zu Kunststoffbehältnissen (20) mitwenigstenseiner Blasform (14), welche wenigstens zwei Blasformseitenteile (14a, 14b) und eine Bodenform (14c) aufweist, wobei die Blasformseitenteile (14a, 14b) und die Bodenform (14c) einen Hohlraum ausbilden, welcher einer Negativkontur des umzuformenden Kunststoffbehältnisses (20) entspricht, wobei zwischenden Blasformseitenteilen (14a, 14b) und der Bodenform (14c) wenigstens eine erste Trennebene (22) und eine zweite Trennebene (24) vorhanden ist, wobei die erste Trennebene (22) zwischen den beiden Seitenteilen (14a, 14b) verläuft und die zweite Trennebene (24) zwischen den Seitenteilen (14a, 14b) und der Bodenform (14c), wobei durch die zweite Trennebene (24) die Blasformseitenteile (14a, 14b) und die Bodenform (14c) voneinander trennbar sind und die Bodenform (14c) durch einen Bodenhubvon den Blasformseitenteilen (14a, 14b) entfernbar ist. Erfindungsgemäß ist zumindest ein Teil der Bodenkontur (15b) der Bodenform (14c) in den Blasformseitenteilen (14a, 14b) angeordnet.
(EN)
A device (1) for forming plastic preforms (10) into plastic containers (20), comprising at least one blow mould (14), which has at least two blow mould side parts (14a, 14b) and a base mould (14c), the blow mould side parts (14a, 14b) and the base mould (14c) forming a cavity, which corresponds to a negative contour of the plastic container (20) to be formed. At least one first separation plane (22) and a second separation plane (24) are provided between the blow mould side parts (14a, 14b) and the base mould (14c), the first separating plane (22) running between the two side parts (14a, 14b) and the second separating plane (24) running between the side parts (14a, 14b) and the base mould (14c), the blow mould side parts (14a, 14b) and the base mould (14c) being separable from one another by the second separating plane (24), and the base mould (14c) being removable from the blow mould side parts (14a, 14b) by a lifting of the base. According to the invention, at least part of the base contour (15b) of the base mould (14c) is arranged in the blow mould side parts (14a, 14b).

L'invention concerne un dispositif (1) pour mouler des ébauches en matières plastique (10) en récipients en matière plastique (20), comprenant au moins un moule de soufflage (14) qui présente au moins deux pièces latérales (14a, 14b) et un fond (14c), les pièces latérales (14a, 14b) et le fond (14c) du moule de soufflage formant une cavité qui correspond à un contour négatif du récipient en matière plastique (20) à mouler. Entre les pièces latérales (14a, 14b) et le fond (14c) du moule de soufflage sont formés au moins un premier plan de séparation (22) et un second plan de séparation (24), le premier plan de séparation (22) s'étendant entre les deux pièces latérales (14a, 14b) et le second plan de séparation (24) étant formé entre les pièces latérales (14a, 14b) et le fond (14c), les pièces latérales (14a, 14b) et le fond (14c) pouvant être séparés les uns des autres par le second plan de séparation (24), et le fond (14c) pouvant être séparé des pièces latérales (14a, 14b) du moule par un déplacement linéaire du fond du moule. Selon l'invention, au moins une partie du contour (15b) du fond (14c) du moule est agencée dans les pièces latérales (14a, 14b) du moule de soufflage.
