Title (EN) NOZZLE AND METHOD OF MAKING THE SAME
(FR) BUSE ET SON PROCEDE DE FABRICATION
Abstract:
(EN) A method for forming an embodiment of a fluid nozzle assembly (10) includes removing two cores (20, 22) in opposed directions from a die set having a mold cavity configured to be a negative replica of the fluid nozzle assembly. The cavity includes the two cores, with one core configured to be a negative replica of : a fluid connector receiving bore (24) ; an inlet region (26) of a nozzle; and a pass-through conduit (30), each m fluid communication with the fluid connector receiving bore. The other core is configured to be a negative replica of an outlet region (28) of a nozzle m fluid communication with the inlet region. Removing the cores forms the nozzle assembly after molten polymeric material injected into the mold cavity has solidified. Removing leaves substantially no flash: at an area where the inlet region and the outlet region meet; and at an end region (36) of the pass- through conduit distal to the receiving bore.
(FR) L'invention concerne un procédé permettant de former un mode de réalisation d'un ensemble buse pour fluide qui consiste à évacuer deux noyaux dans des directions opposées d'un ensemble matrice doté d'une cavité de moulage conçue pour être une réplique négative de l'ensemble buse pour fluide. Ladite cavité comporte deux noyaux, l'un étant conçu pour être une réplique négative d'un alésage de réception de connecteur fluidique; d'une zone d'admission d'une buse; et d'un conduit traversant, chacun en communication fluidique avec l'alésage de réception de connecteur fluidique. L'autre noyau est conçu pour être une réplique négative d'une zone de sortie d'une buse en communication fluidique avec la zone d'admission. L'évacuation des noyaux forme l'ensemble buse une fois solidifié le matériau polymère fondu injecté dans la cavité de moulage. L'évacuation ne laisse sensiblement aucune bavure: au niveau d'une zone où les régions d'admission et de sortie se rencontrent; et au niveau d'une région d'extrémité du conduit traversant distal par rapport à l'alésage de réception.
