Background technology
Injection moulding is one of main method of plastics processing, and almost all of thermoplastic and part thermosetting plastics all can use injection system molding, and therefore injection moulding has consequence in plastics industry.
The effect of injection machine injecting systems is to melt as macromolecule melt by the macromolecule pellet in barrel or powder after plasticizing, then under high pressure and high speed, melt is injected die cavity, and provide maintenance pressure at packing stage subsequently, make polymer go successively to die cavity to fill up the contraction caused due to cooling；The quality of plasticizing injecting device performance not only directly influences the problems such as injection molding efficiency, production cost and production environment, but also the quality of injected articles is had conclusive impact.
Present modal plasticizing injecting device has two kinds, first screw plunger type, and it two is reciprocating screw type.
Classic screw plunger injection forming machine, it is on plunger injection device, add a set of Single screw extrusion feeding device only doing plasticizing, material need to first pass through single spiro rod plasticizing device and plastify, then injection barrel is entered through check valve, when feed quantity reaches variable, plasticized screw stops operating, and injection piston starts injection.This kind of mode problematically, the problem such as structure is not compact and barrel cleaning is inconvenient, owing to needing two sets barrel (a set of plasticizing, a set of injection), increase machine volume and amount of parts, manufacturing cost is high.
Traditional reciprocating screw type injection (mo(u)lding) machine, eliminate injection piston, screw rod has plasticizing and two functions of injection simultaneously, screw rod not only to do gyration to complete the plasticizing to material, also to do reciprocal axially-movable to inject simultaneously, this just requires at screw design and in addition special consideration in connecting transmission etc., considerably increase complexity and the difficulty of total system, manufacture, use and maintenance cost all increase, and, when plasticizing, because of moving axially along with screw rod, the axial temperature difference that melting material temperature is formed is relatively big, and is difficult to overcome.
