Title (EN) ROTARY VALVE
(FR) VANNE ROTATIVE
Abstract:
(EN) An injection molding system including a nozzle member (18) or a valve pin (80) having a tip end (21 ) wherein the nozzle member (18) or valve pin (80) is adapted to be controllably rotatable around a longitudinal rotation axis (A) to enable an exit aperture (20) of the nozzle or the tip end of the pin to interface with a cavity entrance aperture (30) to controllably vary or adjust size (SP1, SP2) of the cross sectional area (CA) of a gate aperture (50) according to degree of rotation (R) of the nozzle or valve pin around the rotation axis (A).
(FR) La présente invention concerne un système de moulage par injection comprenant un élément de buse (18) ou une tige de vanne (80) comportant une extrémité de pointe (21), l’élément de buse (18) ou la tige de vanne (80) étant adapté(e) pour être rotatif(ve) de façon contrôlable autour d’un axe de rotation longitudinal (A) pour permettre qu’une ouverture de sortie (20) de la buse ou de l’extrémité de pointe de la broche soit interfacée avec une ouverture d’entrée de cavité (30) pour faire varier ou ajuster de façon contrôlable la taille (SP1, SP2) de l’aire de section transversale (CA) d’une ouverture de porte (50) en fonction du degré de rotation (R) de la buse ou de la tige de vanne autour de l’axe de rotation (A).
