The invention concerns a system for actuating a two-part mould (1) forming two half-moulds (1, 1 ) mutually articulated about a shaft (2) forming a hinge and driven, between an opening position and a closing position, by a translational carriage (7) driven in a reciprocating movement. The inventive system is particularly characterised in that each half-mould (1, 1 ) is further articulated on a part (4a, 4b) which pivots about a shaft (5a, 5b) and which is driven in rotation by at least an actuating link rod (6a, 6b) articulated through its ends respectively to said pivoting part (4a, 4b) and to said translational carriage (7).
L'invention concerne un système d'actionnnement d'un moule (1) en deux parties formant deux demi-moules (1',1") articulés entre eux autoru d'un axe (2) formant charnière et commandés, entre une position d'ouverture et une position de fermeture, par un chariot translatif (7) mû dans un mouvement de va-et- vient. Le système selon l'invention est notamment remarquable en ce que chaque demi-moule (1',1") est en outre articulé sur une pièce (4a,4b) qui pivote autour d'un axe (5a,5b) et qui est mue en rotation par au moins une bielle d'actionnement (6a,6b) articulée par ses extrémités respectivement à ladite pièce pivotante (4a,4b) et audit chariot translatif (7).
