Injection molding apparatus, has shut-off valve arranged in bore of nozzle, having passage that aligns with outwardly extending melt passages of nozzle, for flow of melt stream

摘要

A nozzle (120) has shut-off valve (150) arranged within a bore that intersects with one of the outwardly extending melt passages (132). The shut-off valve has a passage (162) that aligns with the melt passages of the nozzle, for flow of melt stream to mold cavities (136). The passage of the valve aligns perpendicular to the passages of the nozzle, to prevent the flow of melt stream.
