Description
Technical field
The present invention relates to a kind of injection machine technical field that is used for, especially refer to a kind of screw rod that is used on the injection machine.
Background technology
Existing a kind of patent No. discloses a kind of structure for the Chinese utility model patent that the CN201020548908.3 name is called " the efficient screw in injection molding machine of a kind of pair of rank compression ", and its structure mainly is made up of solid conveying section, compression melt zone, metering homogenizing zone.Wherein the solid conveying section spiral groove depth is constant; The compression melt zone is the compression section, two rank that three segments are formed, and the first segment spiral groove depth is gradually shallow, and the second segment spiral groove depth is constant, and the 3rd segment spiral groove depth is gradually shallow.Metering homogenizing zone spiral groove depth is constant, is made up of two segments, and first segment is conventional thread segment, and second segment is a pineapple mixing refining head structure.Three segment formula structures of compression melt zone help improving fusion and plasticizing quality, and the metering homogenizing zone that has the pineapple mixing refining head helps mixing homogenizing.This novel screw rod is fit to the processing of various materials, highly versatile, and the quality of moulded products is good.But the shortcoming of this screw-rod structure is, spiral shell rib part fracture easily in charging place, and the phenomenon that putty and burnt material can occur, reason is that the spiral shell rib spacing of charging place is identical and thinner, and is smooth department on the spiral shell rib, so easy anti-glue during charging, be difficult for charging and putty, Jiao's material occurs owing to charging has some setbacks again, the charging aperture rotation torsion bigger because of putty will increase is arranged again, concentrate and cause easily the screw rod fracture thereby stress occurs.So its structure awaits to improve.
Summary of the invention
Technical problem to be solved by this invention be provide at above-mentioned prior art present situation a kind of feed zone not easy fracture, can not burnt material and can not occur a kind of screw rod of anti-glue during feeding.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this screw rod, include feed zone, fluxing zone and extruding zone, described fluxing zone and extruding zone are provided with the spiral shell rib, it is characterized in that: described feed zone is provided with the spiral shell rib of the branch of height, pitch ratio on wherein adjacent high spiral shell rib and pitch between the low spiral shell rib and the fluxing zone between the adjacent two spiral shell ribs is 1: 2～3, and the difference in height of described high spiral shell rib and low spiral shell rib is 11～13mm.
As improvement, the interior angular radius of the bottom left of spiral shell rib is preferably 20mm in the described feed zone.
As further improvement, in the described feed zone between spiral shell rib side and the vertical line angle be chosen as 10 degree.
Improve, angular radius may be selected to be 16mm in the right bottom of described feed zone spiral shell rib again.
Improve again, but on the described high spiral shell rib periphery also the compartment of terrain be distributed with breach.
Improve, described breach bottom can be preferably circular arc again; Angle between the described breach left side and the right can be designed to 60 degree.
Improve, the difference in height of described high spiral shell rib and low spiral shell rib can be preferably 12mm again.
Improve again, described fluxing zone is provided with and disconnects the spiral shell rib and do not disconnect the spiral shell rib, described disconnection spiral shell rib compartment of terrain is distributed in the rear portion of fluxing zone, describedly do not disconnect the front portion that the spiral shell rib is distributed in fluxing zone, adjacent two pitch ratios that do not disconnect between the spiral shell rib are 1: 2～3 on described adjacent high spiral shell rib and pitch between the low spiral shell rib and the fluxing zone.Disconnection spiral shell rib on the fluxing zone can effectively improve plasticizing effect, makes plasticizing more even, more perfect.
Compared with prior art, the present invention adopts feed zone to be provided with the spiral shell rib of the branch of height, pitch ratio on wherein adjacent high spiral shell rib and pitch between the low spiral shell rib and the fluxing zone between the adjacent two spiral shell ribs is L: H=1: 2～3, and the difference in height of described high spiral shell rib and low spiral shell rib is 11～13mm.The advantage of this structure is: at first, because the spiral shell rib density of feed zone is bigger than the spiral shell rib density of fluxing zone, so the material of feeding charging aperture can flow to the big direction in space, thereby reduced the stress of feed zone screw rod and improved disconnected performance of resisting of feed zone screw rod, next is, the spiral shell rib of feed zone has the branch of height, so just can better the material that feeds charging aperture be involved in the barrel of charging aperture, thereby eliminate the anti-glue phenomenon that charging aperture occurs; The material that so-called anti-glue refers to feed in the charging aperture can not advance inward, and can stay in above the charging aperture, and when serious, the material that enters charging aperture also can outwards spue from charging aperture.Have again, the compartment of terrain is distributed with breach on the spiral shell rib periphery of feed zone of the present invention, these breach can be involved in charging better with charging during along with the rotation of screw rod and carry to fluxing zone, thereby have further promoted the material of charging aperture to move inward, and eliminate the anti-glue phenomenon of charging aperture.In sum, screw rod of the present invention can prevent fracture effectively, material is flowed to fluxing zone from feed zone, no matter be the conveying capacity of whole screw rod, still the effect of plasticizing dispersion all has significant raising, pay attention to the reasonable distribution of functional areas simultaneously, improved the intensity of whole screw rod then.So the present invention is a kind of very practical product, is worthy of popularization.
