Description
Technical field
The utility model relates to a kind of mixed milling type injection molding machine of plastic, belongs to polymer material molding mechanical field, is particularly applicable to medium-sized and large size plastic jetting-moulding device.
Background technology
Injecting systems is one of topmost part of injection machine, injecting systems is topmost act as plasticizing and injection, namely on the one hand the material added in feeding cylinder is heated, its temperature is made to reach the melt temperature of material, after preformed completes, pressure is applied to the material of melting on the other hand, enable material be full of whole mold cavity.Therefore, to the requirement of injecting systems be namely the ability having stronger plasticizing capacity, enough injection pressures, injection speed and accurate-metering feed.According to the difference of structure, injecting systems can be divided into plunger type, screw and screw rod preformed plunger injection formula three kinds, most widely used is segment injection system at present, material relies on the shearing of screw rod and external heat and plastifies, pressure due to screw rod generation is pushed to the front end near nozzle, while bolt rotary, barrel is moving gradually afterwards, and when reaching certain position, screw rod stops operating and the material be accumulated near nozzle segment is entered mould inside with certain pressure injection.Screw rod preformed plunger injection formula injecting systems is by screw rod to complete plastication equally, but is come injection to material and metering process by plunger with screw unlike, screw rod preformed plunger injection formula injecting systems.
The screw rod adopted in segment injection system and screw rod preformed plunger injection formula injecting systems mostly is singe screw, now, screw rod can only play melting, conveying, metering, injection effect and cannot carry out blended to material.But the current situation using pure resin to carry out injection molding is less, even for the goods injection moulding with color requirement, material all needs to carry out mixing granulation by twin-screw or other blended formers before injection moulding, this not only makes the performance of material change but also wastes a large amount of energy, increase production link, improve production cost.
Patent ZL2008200655772.3 discloses a kind of plastic pugging injection device.This device adopts the singe screw in parallel or conical double-screw replacement screw injection system, twin-screw is utilized to carry out blending and modifying to material, achieve mixing, the integration of Shooting Technique, the conveying capacity of material is larger, shear evenly, but injection process needs to rely on hydraulic pressure or other mechanical forces to promote two screw rods injects mould by front end material simultaneously, the resistance that needs overcome is very large, complex structure, and it is less owing to shearing number of times in twin-screw each screw channel material chamber, easy generation is heated inequality, thus cause plasticizing uneven, the material injecting mould may be produced and fill discontented phenomenon.
Annular multiscrew refer to even number root in the same way screw rod distribute around central mandrel, intermeshing structure between two between screw rod, and the mandrel of centre is containing screw thread, its effect forms ring screw and the interactional space of material together with machine tube inner wall.Annular multiscrew is equivalent to the structure that multiple twin-screw is interconnected, and screw rod often rotates a circle all can increase the number of times of mixing of materials, homogenizing, kneading and shearing, and material is heated comparatively even, the melting of equipment and the ability of dispersion mixing strong.
