Abstract

Moule pour la production d'objets en matière plastique en particulier d'objets comportant un matériau de renforcement comme des objets en résine de polyester renforcés par des fibres. Des éléments de moule rigides susceptibles d'être déplacés l'un par rapport à l'autre, et au moins un raccord d'aspiration pour une conduite d'aspiration permettent d'abaisser la pression dans le volume creux du moule. Il présente une zone d'étanchéité qui s'étend sensiblement le long du bord extérieur de la cavité du moule et qui obture celle-ci après aspiration partielle. A l'extérieur de ladite zone d'étancheité, est prévu, isolé de façon étanche par rapport au milieu environnant, un volume de post-compactage dans lequel débouche le raccord d'aspiration et qui est fermé entre la zone d'étanchéité et son pourtout extérieur par des parois rigides, qui sont fixées chacune à un des élements de moule déplaçables les uns par rapport aux autres. Moulage d'objets en matière plastique renforcée.Mold for the production of plastic articles, in particular articles comprising a reinforcing material, such as articles of polyester resin reinforced with fibers. Rigid mold elements capable of being displaced relative to one another, and at least one suction connection for a suction line, make it possible to lower the pressure in the hollow volume of the mold. It has a sealing zone which extends substantially along the outer edge of the mold cavity and which closes the latter after partial suction. Outside said tightness zone, there is provided, sealed off from the surrounding environment, a post-compacting volume into which the suction connection opens and which is closed between the sealing zone and its for all exterior by rigid walls, which are each fixed to one of the movable mold elements relative to each other. Molding of reinforced plastic objects.
