Nozzle piece for an injection moulding nozzle, injection moulding nozzle and injection moulding tool

摘要

The nozzle mouthpiece (1) has a flow channel (10) with an inlet opening (11) and an outlet opening (12), where a cylindrical sealing surface (20) is formed radially with respect to a longitudinal axis (L). A stop surface (32) is arranged between the sealing surface and the outlet opening. The stop surface is aligned perpendicular to the longitudinal axis and facing the outlet opening. A coupling unit (40) is arranged radially with respect to the longitudinal axis for fixing the nozzle mouthpiece in a mold sprue opening (202) of a pattern plate (201). Independent claims are included for the following: (1) an injection molding nozzle for use in injection molding tool and for processing a fluid mass; and (2) an injection molding tool.
