摘要： A rotating feed screw in the barrel of an injection molding machine is fitted with a collar with peripheral grooves through which the plasticized material is fed into a charge forming chamber. The collar is held onto the end of the feed screw by an elongated torpedo body, which body has a first portion for receiving the annular collar, a second portion which defines a plurality of helically oriented crisscrossing grooves in its cylindrical surface, and a third axial portion which defines a raceway for a plurality of spherical roller elements. A nonreturn valve in the form of an annular shuttle is slidably received on the second axial portion, and also slidably received in the bore which rotatably receives the screw, so that the plasticized material is required to pass through the above mentioned grooves and around the ball elements. Thus, the ingredients are mixed in several stages prior to being injected through a nozzle provided in the head of the barrel, into the mold cavity.

摘要： An extruder-mixer has a plurality of rotor rings provided on the downstream end of a motor driven extruder shaft mounted for rotation in a conventional heated barrel or stator. The rings comprise a plurality of spaced driven rotor rings spaced apart from each other and a plurality of non-driven but rotatable floating rings interleaved between each pair of driven rotor rings. Both rings have parallel upstream and downstream faces between which polymer flow passageways extend so that the polymer melt moves downstream first through one type of ring followed by movement through the other type of ring and the viscosity of the melt causes the rotatable floating rings to be rotated by the driven rings at a slower speed than the driven rings so that shearing force on the melt effects mixing of the melt.

摘要： A backflow prevention device for an injection molding machine includes a screw tip having a tip end, a central body member connected to the tip end, a thrust ring at a rear end of the body member, and a mounting end for attachment to a plasticizing screw. A locking ring is arranged at a distance to the body member to define an annular gap and is axially movable between an open position, in which a first sealing surface rests against a shoulder of the tip end, allowing passage of material, and a closed position, in which a second sealing surface rests against a shoulder of the thrust ring, prohibiting entry of material. Disposed in the annular gap coaxial to the locking ring is at least one mixing element in the form of a circular ring which has circumferential bores in spaced-apart disposition for axial material transport.

摘要： Disclosed is an injection unit having a rotatable device for preventing reverse flow. To connect first flow channels formed in a spacer and second flow channels formed in a screw head when the metering is performed, and prevent reverse flow of resin by cutting off the first flow channels and the second flow channels when the resin is injected, the injection unit has a torsion spring as spring means between a shaft of the screw head and a screw, thereby rapidly preventing movement of the melted resin by restoring force of the spring when the metering of the resin is finished.
