Description
Technical Field
The utility model relates to a special screw rod of lens belongs to screw rod technical field.
Background
The quality of the injected product and the production speed are mainly controlled by the individual processes in the injection cycle, wherein the plasticizing quality of the polymer in the preplasticizing process first influences the quality of the product. The production speed is influenced by the time of the preplasticizing process. The screw is a key part for realizing the plasticizing process of the screw type injection machine, and the screw can realize the actions of conveying, compacting, plasticizing, injecting and the like on molding materials, namely high polymers, through rotation and axial movement in the charging barrel. The appearance of the screw in the prior art is simpler, so that the plasticizing effect is poor. In order to solve the above difficulties, a screw rod special for a lens with good plasticizing effect needs to be developed.
Disclosure of Invention
The utility model aims at providing a special screw rod of lens.
The to-be-solved problem of the utility model is that the outward appearance of prior art's screw rod is all fairly simple for the not good problem of plastify effect.
For realizing the purpose of the utility model, the utility model adopts the technical proposal that:
the special screw rod of lens, including screw section, lower terrace body section, obstacle piece, screw section, screw head, go up screw section, arc spiral arris, go up terrace body section, transversely stir piece, half spiral arris and full spiral arris, be equipped with down terrace body section on the screw section, be equipped with the screw section on going up the terrace body section, be equipped with the screw head on going up the screw section, it is equipped with the arc spiral arris to go up the screw section outward, the screw section is equipped with horizontal stirring piece outward, the outer left side of screw section is equipped with a plurality of obstacle pieces, is equipped with a plurality of half spiral arris outward on the screw section, is the disconnection discontinuity between the half spiral arris, and the screw section lower extreme is equipped with top-down's full spiral.
The upper ladder platform body section is of a structure with a large upper part and a small lower part.
The lower ladder platform body section is of a structure with a small upper part and a large lower part.
The screw column section, the lower step body section, the screw column section, the upper step body section and the upper screw rod section form a screw rod body whole.
The utility model has the advantages that: the arc-shaped screw edges can enable the material close to the discharge hole to be more fully torn and stirred, and bubbles in the injected material are avoided; the upper step body section, the lower step body section and the stud section change the mixing of materials through the change of the diameter of the screw rod body, and meanwhile, the transverse stirring block promotes the tearing of the materials; the barrier blocks and the semi-spiral edges can promote tearing of materials, the overall appearance of the screw is complex, and the plasticizing effect is good.
Drawings
FIG. 1 is an overall structure view of the screw dedicated for lens of the present invention;
FIG. 2 is a top view of an arcuate flight;
FIG. 3 is a bottom view of the barrier block;
in the figure: 1. the device comprises a screw column section 2, a lower step body section 3, a barrier block 4, a screw rod section 5, a screw rod head 6, an upper screw rod section 7, an arc-shaped screw ridge 8, an upper step body section 9, a transverse stirring block 10, a semi-screw ridge 11 and a full-screw ridge.
