Title (EN) MOULDS FOR MOULDING OBJECTS MADE OF PLASTICS AND A METHOD FOR PRODUCING A MOULD ELEMENT
(FR) MOULES POUR LE MOULAGE D’OBJETS EN PLASTIQUE ET PROCEDE DE FABRICATION D’ELEMENT DE MOULE
Abstract:
(EN) A mould comprises at least two die parts (2), each die part (2) comprising a recess (71) for forming a portion of an object and conduit means (4) through which a cooling fluid can flow, said conduit means (4) comprising a curved conduit (43) which surrounds said recess (71), an inlet conduit (41) having a supply portion (41a) which leads into said curved conduit (43) and an outlet conduit (42) having a discharge portion (42a) which leaves said curved conduit (43) so as to define a path for said cooling fluid, said curved conduit (43) , said supply portion (41a) and said discharge portion (42a) being arranged sp as to be interceptable by a common plane (40) that contains said path.
(FR) L’invention concerne un moule comprenant au moins deux éléments de matrice (2), chaque élément de matrice (2) comprenant un renfoncement (71) servant à former une partie d’un objet et un moyen de passage (4) permettant l’écoulement d’un fluide de refroidissement et comprenant un passage incurvé (43) entourant le renfoncement (71), un passage d’entrée (41) présentant une partie d’amenée (41a) menant au passage incurvé (43) et un passage de sortie (42) présentant une partie d’évacuation (42a) sortant du passage incurvé (43) de manière à définir un chemin emprunté par le fluide de refroidissement. Le passage incurvé (43), la partie d’amenée (41a) et la partie d’évacuation (42a) étant disposés de façon à être interceptés par un plan commun (40) contenant le chemin.
