Description
Technical field
The present invention relates to injection molding machine nozzle technical field more particularly to a kind of fork ring type screw head groups.
Background technique
Existing master screw head group is that there are three parts to form：Screw head, check ring (crossing cushion rubber), meson, wherein non-return
It is it and screw rod common rotation, therefore screw head group three productions the advantages of ring is divided into V shape and two kinds of ring type, V shape check ring
There is no generate abrasion inside product.The disadvantage is that check ring rotates simultaneously with screw rod, it will cause check ring and expects pipe generate abrasion, contracting
The short service life of expects pipe.The advantages of ring type screw head group be check ring and screw rod will not common rotation, therefore for material
The abrasion of pipe greatly reduces, and improves the service life of expects pipe.The disadvantage is that check ring and screw head can products during colloidal sol
Friction (for the flexibility for guaranteeing screw head, prevents from being broken, the material of check ring and screw head is different, and hardness is also different),
Cause glue gap increasing, and then influence the reflux flow of molten plastic, and causes product quality unstable.
Therefore, to overcome defect of the existing technology, have developed a kind of fork ring type screw head group effectively by V shape and
The advantages of ring type, combines, and check ring is divided into two parts, respectively check ring one and check ring two, reach develop it is excellent
Point inhibits the effect of disadvantage.
Summary of the invention
It is an object of the invention to overcome the deficiencies of existing technologies, the present invention provide a kind of reduction abrasion, reduce use at
This, and improve the stability of precise injection molding product and the fork ring type screw head group of precision.
In order to achieve the above objectives, the present invention adopts the following technical scheme that：A kind of fork ring type screw head group comprising screw rod
Head, check ring one, check ring two and meson, wherein the check ring one, check ring two and meson are sequentially sleeved at the spiral shell
In head, a plurality of groove is evenly distributed in the front end circumferential direction of the screw head, the check ring one is circular ring shape, in the annulus
Multiple protrusions are evenly distributed in shape, multiple protrusions on the check ring one are inserted into the corresponding a plurality of of the screw head
In groove, at one rear portion of check ring, the middle part of the screw head has boss, the meson peace for the setting of check ring two
After the boss.
Further, four grooves are evenly distributed in the front end circumferential direction of the screw head, on the check ring one uniformly
It is raised that there are four distributions, and four protrusions on the check ring one are inserted into corresponding four grooves of the screw head
Place.
Further, the check ring two and meson are circular ring shape, the circular ring shape of the check ring one and check ring two
Diameter is identical, and the aperture of the meson is less than the outer diameter of the boss.
Further, the protrusion of the check ring one is inserted into cooperation in the groove of screw head, and the screw head rotates band
The check ring one is moved to rotate synchronously.
Further, the check ring one and check ring two are made of the material of same material, and hardness is also identical.
Further, the meson is truncated cone.
Further, the outer diameter of the check ring one and check ring two is 10mm to 400mm.
Beneficial effects of the present invention：Fork ring type screw head group through the invention allows abrasion to reduce, and service life can be significantly
It improves, reduces use cost and improve the stability and precision of precise injection molding product.The present invention is applied to the spiral shell of injection molding machine
Bar expects pipe component replaces any screw head group, can improve production efficiency and product quality.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, it illustrates a kind of fork ring type screw head groups of the invention comprising screw head 1, check ring 1,
Check ring 23 and meson 4, wherein the check ring 1, check ring 23 and meson 4 are sequentially sleeved on the screw head 1,
A plurality of groove 5 is evenly distributed in the front end circumferential direction of the screw head 1, the check ring 1 is circular ring shape, on the circular ring shape
Multiple raised 6 are evenly distributed with, multiple raised 6 on the check ring 1 are inserted into the corresponding a plurality of of the screw head 1
In groove 5, at one 2 rear portion of check ring, the middle part of the screw head 1 has boss 7, described for the setting of check ring 23
After meson 4 is mounted on the boss 7.As shown in Figure 1, four grooves 5 are evenly distributed in the front end circumferential direction of the screw head 1,
Raised 6 there are four being uniformly distributed on the check ring 1, four protrusions 6 on the check ring 1 are inserted into the spiral shell
Place in corresponding four grooves 5 of head 1.
As shown in Figures 1 to 4, the check ring 23 and meson 4 are circular ring shape, the check ring 1 and check ring 23
Circular ring shape diameter it is identical, the aperture of the meson 4 is less than the diameter of the boss 7, so meson 4 cannot cross boss 7, is situated between
Son 4 is truncated cone,.
Cooperate since the protrusion 6 of check ring 1 is inserted into the groove 5 of screw head 1, so the meeting when screw head 1 rotates
The check ring 1 is driven to rotate synchronously.The check ring 1 and check ring 23 are made of the material of same material, and hard
It spends also identical.The outer diameter of the check ring 1 and check ring 23 is 10mm to 400mm.
The working principle of the invention：Start storing when board screw rod rotates, front end check ring 1 and screw head 1 turn jointly
It is dynamic, because the outer diameter tolerance of check ring 1 thus is very big, therefore friction can't be generated to expects pipe, plastics pass through check ring 1
Inner hole is fed forward, and rear end check ring 23 will not be with 1 common rotation of screw head, therefore rear end check ring 23 can be non-return with front end
Ring 1 generates friction, but because the two material is identical with hardness, therefore the damage very little generated that rubs, service life can mention significantly
The precision of height, injecting products also can guarantee.When check ring abrasion is larger, the check ring more renewed, cost is relatively low.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those skilled in the art is in technical scope disclosed by the invention, and any changes or substitutions that can be easily thought of, all answers
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be with the scope of protection of the claims
It is quasi-.
