Zusammenfassung:	The present application relates to the technical field of fiber spinning molding, and particularly to a preparation method of an ultra-high molecular weight polyethylene fiber, a spinneret assembly and a multifilament yarn. The spinneret assembly includes a housing, a plate body and an extrusion hole provided in the plate body. The extrusion hole includes a pressurized inlet segment and an outlet segment connected to an end of the pressurized inlet segment. An inner diameter of the pressurized inlet segment is gradually decreased from one end away from the outlet segment to the other end, and the inner diameter of the outlet segment is constant.
