A stack molding apparatus wherein the injection nozzles are disposed in pairs of coaxial nozzles in a housing between two sets of injection molds. The reciprocable valving elements of the injection nozzles of each pair are coaxial with each other and are connected with pistons which are reciprocable by compressed air. The pistons are mounted in cylinders of discrete melt supplying members which receive melt from an additional melt supplying member. The housing has two mirror symmetrical sections which can be parted in a plane between pairs of coaxial pistons to afford access to the melt supplying members, to the pistons, to the nozzles and to a device which serves to supply compressed air for reciprocation of the pistons. The melt supplying members have melt conveying channels which register with each other in assembled condition of the housing sections, and the air supplying device has passages which can admit air directly between pairs of coaxial pistons or into the cylinders of the melt supplying members which carry the pistons and the associated nozzles.

Cette invention concerne un appareil de moulage en grappe dont les buses d'injection sont disposées en paires coaxiales dans un logement prévu entre deux jeux de moules à injection. Les obturateurs va-et-vient des buses d'injection de chaque paire sont coaxiaux et sont raccordés à des pistons à mouvement alternatif animés par air comprimé. Les pistons sont disposés à l'intérieur de cylindres d'alimentation en matière fondue provenant d'une autre source d'alimentation. Le logement susmentionné comprend deux coquilles symétriques réunies par un plan de joint situé entre les paires de pistons coaxiaux et démontables pour donner accès aux cylindres d'alimentation en matière fondue, aux pistons, aux buses d'injection et à un dispositif d'alimentation en air comprimé servant à actionner les pistons. Les éléments d'alimentation en matière fondue comportent des canaux qui sont alignés lorsque les deux coquilles du logement sont assemblées et le dispositif d'alimentation en air comprimé comporte des passages permettant l'entrée d'air directement entre les paires de pistons coaxiaux ou dans les cylindres d'alimentation en matière fondue qui portent les pistons et les buses correspondantes.
