Abstract

Procédé de moulage des voyants transparents en matière thermoplastique à plusieurs éléments colorés de formes quelconques, ayant des côtés communs. Caractérisé par l'injection dans un même moule à deux groupes de pistons et poches monté sur une machine à mouler à plateau tournant à deux postes décalés de demi-tour, des matières thermoplastiques constituant chaque élément coloré. Des languettes sorties de l'élément le plus clair moulé au premier poste viennent séparer les cavités du moule dans lesquelles les autres éléments colorés plus foncés seront injectés simultanément au second poste. Utilisation dans les voyants transparents des feux pour la signalisation en général et plus particulièrement dans ceux employés à bord des véhicules automobiles ou analogues.A method of molding transparent indicators in thermoplastic material with several colored elements of any shape, having common sides. Characterized by the injection into a single mold with two groups of pistons and pockets mounted on a molding machine with a turntable with two stations offset by half a turn, of thermoplastics constituting each colored element. Tabs emerging from the lighter element molded at the first station separate the mold cavities into which the other darker colored elements will be injected simultaneously at the second station. Use in transparent indicator lights for signaling in general and more particularly in those used in motor vehicles or the like.
