Abstract
L'invention a pour objet un système de buse pour une machine à mouler par injection. Le système de buse comprend un bec de buse qui est fixé de manière à pouvoir être enlevé à un corps de buse muni d'un manchon d'étanchéité et de montage. Le corps de buse comprend un premier connecteur conçu pour être raccordé de manière libérable a un second connecteur se trouvant sur le manchon. Le manchon comprend également un palier d'alignement conçu pour entrer en contact avec une surface d'appui se trouvant sur le corps de buse de manière à fixer précisément le bec de buse dans le corps de buse le long d'un axe prédéterminé. D'autres modèles de l'invention présentent une goupille de soupape disposée dans le corps de buse et dans le bec de buse. La goupille de soupape comprend une surface d'appui conçue pour entrer en contact avec une surface de guidage se trouvant sur le canal de seconde fonte afin d'aligner l'extrémité de la goupille de soupape avec une porte de moulage. D'autres modèles présentent également un bec de buse raccordé à un manchon dans un ensemble intégré.
