A valve gating apparatus for injection molding including at least one shutter (12) disposed between the gate and the cavity melt channel into a mold cavity (8). The shutter (12) is removably fastened to a rail member (11). When the rail member (11) is moved laterally, the shutter (12) moves between a closed position wherein flow of melt from the nozzle (1) into the cavity (8) is inhibited, and an open position wherein flow of melt into the cavity (8) is unimpeded by the shutter (12).

La présente invention concerne un appareil d'obturation pour moulage à injection comprenant au moins un volet amovible (12) placé entre l'obturateur et le filet de la zone de fusion dans la cavité d'un moule (8). Le volet amovible (12) est fixé de façon amovible à un élément rail (11). Lorsque l'élément rail (11) est déplacé latéralement, le volet (12) se déplace entre une position fermée dans laquelle il empêche l'écoulement de la matière fondue depuis le nez (1) d'injection et une position ouverte dans laquelle il permet l'écoulement de la matière fondue.
