Description
Technical field
The utility model relates to a kind of manufacture technology field of screw rod, especially a kind of extrusion screw rod for injection moulding.
Background technology
Existing a kind of patent No. is 200920140357.4 and is called that the Chinese utility model patent of " gradual change mixing type screw " discloses a kind of gradual change mixing type screw, its structure comprises rotary head, the body of rod and external screw thread, rotary head and the body of rod are fixed together, the body of rod there is external screw thread, the body of rod is feed end near one end of rotary head, the other end of the body of rod is discharge end, this body of rod is divided into 6 sections, the first fluxing zone is sequentially from the feed end of the body of rod to discharge end, second gradual change footpath fluxing zone, 3rd fluxing zone, melt compounded section, blowing agent and mixing of materials section and mixture deferent segment.This mixing type screw rod is easy to use, improves the melting effect of fused materials.But its screw rod color blending effect is poor, easily there is the phenomenon such as putty and burnt material, so the structure of this screw rod also needs further improvement.
Summary of the invention
Technical problem to be solved in the utility model provides for above-mentioned prior art present situation the extrusion screw rod for injection moulding that a kind of color blending effect is good, plasticizing capacity is strong.
The utility model solves the problems of the technologies described above adopted technical scheme: this is used for the extrusion screw rod of injection moulding, include feed zone, melt zone, fluxing zone, extruding zone, at described feed zone, melt zone, fluxing zone, extruding zone is provided with spiral shell rib, it is characterized in that: the pitch of described feed zone spiral shell rib is equal, described melt zone is many spaced spiral shell rib compositions arranged side by side side by side, on every bar spiral shell rib arranged side by side, interval is arranged with projection, the plasticizing spiral shell rib hand of spiral of described fluxing zone is contrary with the hand of spiral of feed zone spiral shell rib, and plasticizing spiral shell rib is two tooth spiral shell ribs, two tooth spiral shell rib pitch at interval are equal with the pitch of feed zone spiral shell rib, described extruding zone comprises pitch and is greater than the pitch of feed zone spiral shell rib and the hand of spiral single spiral shell rib section contrary with the hand of spiral of feed zone spiral shell rib and be provided with the mixing section of two mixing refining heads in tandem on Screw Extrusion head.
As improvement, two thread spacing of each pair of tooth spiral shell rib are preferably 2 ~ 3cm.
Further improvement, described two mixing refining heads is preferably provided with respectively the mixing spiral shell rib of oblique strip shaped.
Further improvement, described spiral shell rib upper protruding block arranged side by side is preferably the different lug composition of height.
As improvement, described feed zone: melt zone: fluxing zone: single spiral shell rib section: the distance of mixing section is than being preferably: 3: 1: 3: 2: 1.
As improvement, described feed zone: melt zone: fluxing zone: single spiral shell rib section: the spiral shell edge surface of mixing section is preferably provided with one deck nitration case respectively.
Further improvement, the thickness of described nitration case is preferably 0.4 ~ 0.7mm.
Compared with prior art, extrusion screw rod of the present utility model adopts melt zone, fluxing zone, extruding zone, melt zone is many spaced spiral shell rib compositions arranged side by side side by side, on every bar spiral shell rib arranged side by side, interval is arranged with projection, thus effectively improve plasticizing capacity, decrease the generation of putty and burnt material situation simultaneously, extruding zone comprises the hand of spiral single spiral shell rib section contrary with the hand of spiral of feed zone spiral shell rib and is provided with the mixing section of mixing refining head, then increase the color blending effect of screw rod further, improve the plasticizing capacity of screw rod better.
