A flow nozzle (10) that conveys plastic melt from an injection unit of a molding machine to a mold cavity (72) has an improved, removable seal design. The nozzle body (12) is designed to threadedly receive a nozzle tip (24) that includes an outlet (30) that communicates with the mold cavity. A thin-wall, cylindrical seal ring (40) includes a compression portion that is received between the nozzle body and nozzle tip and is compressed to create a seal between these two elements when the tip is assembled to the nozzle body. The seal ring further includes a sealing portion (50) that encircles the nozzle tip and has an outer diameter slightly larger than the outer diameter of the nozzle body.
L'invention concerne une buse d'injection (10) acheminant du plastique en fusion entre une unité d'injection d'une machine à mouler et une cavité de moulage (72), et comprenant un joint amovible de conception améliorée. Le corps de cette buse (12) est conçu pour recevoir par filetage un embout de buse (24) pourvu d'une sortie (30) communiquant avec la cavité de moulage. Un anneau d'étanchéité cylindrique à parois fines (40) comprend une partie de compression reçue entre le corps de la buse et l'embout de buse et comprimée de manière à former un joint entre ces deux éléments lorsque ledit embout est monté sur le corps de la buse. Cet anneau d'étanchéité comprend également une partie d'étanchéité (50) entourant l'embout de buse et possède un diamètre extérieur légèrement plus important que le diamètre extérieur du corps de la buse.
