Abstract
A kind of injection screw, successively by being made up of feed zone, melt zone, fluxing zone, uniform segment, extruding zone, spiral shell rib is respectively arranged with the feed zone, melt zone, fluxing zone, it is characterised in that：Secondary spiral shell rib is arranged at intervals with the spiral shell rib of the melt zone, the pitch of the secondary spiral shell rib from left to right is gradually increase successively, the uniform segment is cylinder, placed side by side on the outer peripheral face of cylinder and screw channel is distributed with, the extruding zone is made up of thin spiral shell rib and screw rib, the screw rib is distributed between the pitch of thin spiral shell rib, two groups of screw ribs are arranged between the pitch of each thin spiral shell rib, the spacing difference of left thin spiral shell rib to left screw rib to right screw rib to the right thin spiral shell rib is equal, and the screw rib is the spiral shell rib that curl lines are spaced by multiple studs.It the advantage is that：Material is gradually strengthened in the pressure that melt zone is subject to, and realizes the abundant melting of material；Extruding zone more uniformly spreads the material for leaving uniform segment, facilitates material metering, is molded accurate measurement, and injection effect is good.
Description
Technical field
A kind of plastic processing screw rod manufacture technology field is the utility model is related to, especially a kind of injection screw.
Background technology
A kind of existing Application No. CN201020115141.5 is entitled《Injection molding screw structure of injection molding》China it is practical
New patent discloses a kind of injection molding screw structure of injection molding, and the screw rod includes three pan feeding section, compression section and metering section functions
Section；Wherein, some first depressed parts in the same direction with screw rod direction of rotation are provided with the shaft of screw rod pan feeding section, to accelerate pan feeding
With raising blanking ability；Some second depressed parts reverse with screw rod direction of rotation can be separately provided with the screw rod of compression section, by
This, which is improved, is kneaded uniformly, while avoids the generation of bubble and flow liner.But its shortcoming is, compression section melting effect is undesirable, so
Its structure needs to improve.
The content of the invention
Technical problem to be solved in the utility model be for above-mentioned state of the art and provide it is a kind of simple in construction,
Material melts are abundant, and material extrudes uniform injection screw.
Technical scheme is used by the utility model solves above-mentioned technical problem：This injection screw, successively by there is charging
Section, melt zone, fluxing zone, uniform segment, extruding zone composition, spiral shell rib is respectively arranged with the feed zone, melt zone, fluxing zone,
It is characterized in that：Secondary spiral shell rib is arranged at intervals with the spiral shell rib of the melt zone, the pitch of the secondary spiral shell rib from left to right is successively
Gradually increase, the uniform segment are cylinder, are placed side by side on the outer peripheral face of cylinder and screw channel is distributed with, the extruding zone is by thin spiral shell
Rib and screw rib composition, the screw rib are distributed between the pitch of thin spiral shell rib, and two are arranged between the pitch of each thin spiral shell rib
Group screw rib, the spacing of left thin spiral shell rib to left screw rib to right screw rib to the right thin spiral shell rib distinguish equal, the screw rib
It is the spiral shell rib that curl lines are spaced by multiple studs.
As an improvement, the cylindrical diameter of the uniform segment and the spiral shell rib on the feed zone, melt zone and fluxing zone are straight
Footpath is identical.
Further improve, the screw channel on the uniform segment preferably for it is a plurality of be arranged parallel to each other it is spiral helicine recessed
Groove.
As an improvement, the length of the extruding zone is preferably distance of 2 times more than or equal to uniform segment.
As an improvement, equal length of the feed zone preferably with fluxing zone, and the length of the feed zone be more than
Or distance of 2 times equal to uniform segment.
As an improvement, the length of the melt zone is preferably the distance more than or equal to 3 times of feed zone and extruding zone.
Compared with prior art, the utility model has the advantage of be arranged at intervals with secondary spiral shell rib, institute on the spiral shell rib of melt zone
The pitch of secondary spiral shell rib from left to right is stated as gradually increase, material are gradually strengthened in the pressure that melt zone is subject to successively, realizes material
Abundant melting；Extruding zone is made up of thin spiral shell rib and screw rib, and the screw rib is distributed between the pitch of thin spiral shell rib, Mei Gexi
Two groups of screw ribs are arranged between the pitch of spiral shell rib, the left thin spiral shell rib to left screw rib to right screw rib is between right thin spiral shell rib
Equal away from difference, the screw rib is the spiral shell rib that curl lines are spaced by multiple studs, makes to leave uniform segment
Material is more uniformly spread, and facilitates material metering, is molded accurate measurement, and injection effect is good.

Fig. 2 is Fig. 1 front projection figure；
Fig. 3 is Fig. 2 side projection figure；
Fig. 4 is Fig. 2 another side perspective view.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figures 1 to 4, the injection screw of the present embodiment, successively by have feed zone A, melt zone B, fluxing zone C,
Even section of E, extruding zone F are formed, and spiral shell rib 1 is respectively arranged with the feed zone A, melt zone B, fluxing zone C, the melt zone B's
Secondary spiral shell rib 11 is arranged at intervals with spiral shell rib 1, the pitch of the secondary spiral shell rib 11 from left to right is gradually increases successively, the uniform segment
E is cylinder, is placed side by side on the outer peripheral face of cylinder and screw channel 2 is distributed with, the extruding zone F is by 31 groups of thin spiral shell rib 3 and screw rib
Into the screw rib 31 is distributed between the pitch of thin spiral shell rib 3, and two groups of screw ribs are arranged between the pitch of each thin spiral shell rib 3
31, the spacing difference of the left thin spiral shell rib to left screw rib to right screw rib to right thin spiral shell rib is equal, the screw rib 31 be by
Multiple studs are spaced the spiral shell rib of curl lines.The cylindrical diameter of the uniform segment E and the feed zone A, melt
