The technical scheme that the utility model solve the technical problem employing is:
A kind of four oil cylinder injection mechanisms that are used for injection-moulding device are provided, comprise an injection plate, injection cylinder component, screw rod retainer ring, injection two board components, piston rod locking nut, barrel locking nut, injecting screw assembly, barrel assembly and pedestal; Described injection two board components comprise injection two plates, hydraulic oil motor, bearing and shaft coupling; A described injection plate is screwed the upper surface at described pedestal; Described barrel assembly one end passes the installing hole of a described injection plate, and fixes with described barrel locking nut; Described injecting screw assembly is installed in the chamber thorax of described barrel assembly, and its injecting screw exsertion part inserts in the installing hole of described shaft coupling; Described screw rod retainer ring is stuck in the injecting screw groove of described injecting screw assembly and is screwed on described shaft coupling; Described injection cylinder component has four, and these four injection cylinder components are installed in respectively in four deep holes of a described injection plate, and its two ends are screwed; The injection piston rod exsertion part of described each injection cylinder component passes the installing hole of described injection two plates, and fixes with described piston rod locking nut.The reciprocating motion of the injection piston rod of described four injection cylinder components drives described injection two board components and reciprocatingly slides on described pedestal, the action that makes the injecting screw assembly make injection and take out glue in the barrel assembly.
Above-mentioned four injection cylinder components are arranged in parallel on four seamed edges of rectangular cylinder, and described injecting screw assembly and described four injection cylinder components are parallel to each other and arrange and be positioned on the central symmetry axes of described rectangular cylinder.
Compare with prior art, the beneficial effect that the utility model is used for four oil cylinder injection mechanisms of injection-moulding device is:
1, owing to adopts four injection cylinder components, providing for the injecting screw assembly under the situation of equal thrust, the cylinder diameter of each injection oil cylinder can narrow down to 0.707 times of oil cylinder cylinder diameter of two oil cylinder injection mechanisms, parts are also corresponding reduces for relevant structural member such as an injection plate, injection two plates etc., thereby its production and material cost are all reduced, reached the purpose that reduces cost.The model of producing as our company is the injector injection mechanism of EH1300, initial stage is adopted two oil cylinder injection mechanisms, an injection plate appearance and size is 1400 millimeters * 810 millimeters * 760 millimeters, weight is 2000.96 kilograms, injection two plate appearance and sizes are 1190 millimeters * 753 millimeters * 542 millimeters, and weight is 1290.38 kilograms; After using four injection oil cylinder mechanisms instead, an injection plate appearance and size is 1216 millimeters * 770 millimeters * 720 millimeters, and weight is 1681.0 kilograms, and injection two plate appearance and sizes are 1020 millimeters * 733 millimeters * 450 millimeters, and weight is 824.0 kilograms; Use same material QT500-7, but these two parts are with regard to 786.34 kilograms of economical with materials;
2, since injection oil cylinder and relevant structural member thereof such as the size of each motion parts such as an injection plate, injection two plates reduce, thereby can reduce each motion parts motional inertia and improve the injection control accuracy;
3, four injection cylinder components are arranged in parallel on four seamed edges of rectangular cylinder, injecting screw assembly and four injection cylinder components are parallel to each other and arrange and be positioned on the central symmetry axes of described rectangular cylinder, shorten to reach compact conformation, axial dimension, force-bearing situation more becomes reasonable.
