摘要： In a melting and conveying device for a plastic injection molding machine, having a melting cylinder with a cylindrical bore therein and a worm member in said cylindrical bore, a degasser, comprising, a vent pin extending into the melting cylinder in a degassing zone of the cylinder bore. The vent pin defines a widened charging pocket which communicates with the cylindrical bore and has a vent opening therethrough communicating the pocket to the atmosphere. A pair of heating elements extend into suitably provided openings in the vent pin to selectively heat the vent opening and pocket independently of any heating elements of the plastic injection molding machine to prevent clogging of the pocket and vent opening by solidified plastic material.

摘要： A plasticizing device for an injection molding machine for plastics comprises a screw housing having a cylindrical plastic material chamber at one end having a discharge opening. A cylindrical screw is rotatably and axially displaceably mounted in the housing and has a screw head portion adjacent the discharge with an intermediate body portion of reduced diameter adjacent the head portion and a uniform diameter portion on the opposite side of the intermediate portion from the head portion. The uniform diameter portion carries a spiral screw thread which projects radially outwardly from the surface of the screw. A seal ring having an outer periphery engaged with the interior of said screw housing and having an interior diameter greater than and spaced radially outwardly from the intermediate portion of the screw defines a plasticizing material passage with the intermediate portion which connects through a passage defined between a seal washer on the screw which cooperates with the seal ring. In addition a plurality of axially extending and circumferentially spaced passages are defined around the periphery of the screw adjacent the seal washer. These passages may be defined on a separate insert or on a plurality of axially arranged inserts and in this latter case the adjacent inserts are rotated relatively to each other so that the passages are not directly communicated but are offset.
