SLIDING VALVE GATE WITH INSERTS

摘要

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).
