Description
Technical field
The present invention relates to a kind of screw in injection molding machine, more particularly to a kind of injection screw group of integral type.
Background technology
Existing screw in injection molding machine head is all divided into three parts, screw head, check ring（Cross cushion rubber）, meson (pad）, screw head
On have thread, screw head is connected with screw rod by thread, but if screw diameter is to below 14MM, screw head thread be M6 with
Under, such connected mode makes screw head without mechanical strength, to being easily broken off screw head and screw front end, screw rod and spiral shell
Head service life reduction, affects product quality and production efficiency.
Therefore, prior art existing defects.
The content of the invention
It is an object of the invention to overcome the defect of prior art, the present invention provides a kind of integral type screw rod group, solves
The screw rod of minor diameter and the problem of screw head mechanical strength, to solve problems of the prior art.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：A kind of integral type screw rod group, which includes screw rod and spiral shell
Head, the screw head are arranged on screw front end, and the screw head is by being processed into taper formation, institute in the front end of screw rod
State screw rod and screw head is wholely set as overall structure.
According to one aspect of the present invention, wherein, the integral type screw rod group also includes check ring, and the check ring is arranged
After screw head, its internal diameter is less than outer screw diameter.
According to one aspect of the present invention, wherein, the integral type screw rod group also include meson, the meson be by
Groove is set on stud, and welding alloy is formed in the groove.
According to one aspect of the present invention, wherein, the groove is arranged on the same circle of stud, and is set to multiple spot, often
All welding alloy on individual groove.
According to one aspect of the present invention, wherein, the screw front end external diameter makes its external diameter less than non-return by Vehicle Processing
Ring internal diameter, is inserted in after check ring from screw front end, the welding alloy on the external diameter of screw head, the screw head diameter after welding alloy
More than check ring internal diameter.
According to one aspect of the present invention, wherein, the alloy welding manner of the screw head is outer-type, in screw head
Upper multi-point welding alloy
Beneficial effect：
The present invention eliminates connection between the two, reduces by screw rod and screw head are wholely set as overall structure
The impact to mechanical strength that connection brings, improves making for the mechanical strength of screw rod and screw head, prolongation screw rod and screw head
With the life-span, product quality and production efficiency are improved, the mechanical strength for making it possible to solve screw rod under minor diameter with screw head is asked
Topic.
Description of the drawings
Fig. 1 is a kind of structural representation of integral type screw rod group in the present invention；
Fig. 2 is a kind of sectional view of the screw head welding alloy in the present invention in integral type screw rod group；
Fig. 3 is a kind of sectional view of the meson welding alloy in the present invention in integral type screw rod group.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As shown in figure 1, a kind of Contiuum type integral type screw rod group, which includes screw rod 1 and screw head 2, and the screw head 2 is arranged
In 1 front end of screw rod, the screw head 2 is by being processed into taper formation, the screw rod 1 and screw head 2 in the front end of screw rod 1
It is wholely set as overall structure.By screw head and screw head are wholely set as overall structure, connection between the two is eliminated,
Reduce the impact to mechanical strength that brings of connection, improve the mechanical strength of screw head and screw head, extend screw head and
The service life of screw head, improves product quality and production efficiency, makes it possible to solve the screw rod and screw head under minor diameter
Problems of mechanical strength, the injection screw head being applied under minor diameter.
As shown in Fig. 2 the integral type screw rod group also includes check ring 4, after the check ring is arranged on screw head, its
Internal diameter is less than outer screw diameter.1 front end external diameter of the screw rod makes its external diameter less than 4 internal diameter of check ring by Vehicle Processing, from before screw rod
After check ring is inserted at end, the welding alloy 20 on the external diameter of screw head 2, the screw head 2 after welding alloy is with diameter greater than check ring 4
Internal diameter.The alloy welding manner of the screw head is outer-type, the multi-point welding alloy on screw head.Specifically, first
By screw head diameter by Vehicle Processing mode by its external diameter car little to less than check ring internal diameter, non-return ring set is put into into screw head
It is interior, then screw head external diameter alloy is welded, until screw head external diameter is more than check ring internal diameter, does not allow check ring de- from front end
Go out, while the internal diameter of check ring is less than outer screw diameter, so check ring two ends all reach fixation, Jie to be formed is welded by alloy
Subfunction increased its wearability, to increase the stable wearability of meson.Welded by alloy, increase screw rod, the machine of screw head
Tool intensity, reaches not easy fracture, improve quality, to be applied to microminiature screw in injection molding machine.The screw rod which is welded such as Fig. 1 institutes
Show.
As shown in figure 3, the integral type screw rod group also includes meson 3, the meson 3 is by arranging recessed on stud 1
Groove, welding alloy is formed in the groove.Being welded by alloy increases the wearability of stud, to realize the function of meson, described
Groove is arranged on the same circle of stud, and is set to multiple spot, welding alloy on each groove.What the groove and alloy were welded
Quantity visually arranges 4 grooves at equal intervals depending on concrete required abrasion resistance, preferably, and in each groove welds conjunction
Gold, is connected to containing gold solder and fills up groove and be defined.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any
Those skilled in the art in technical scope disclosed by the invention, all answer by the change or replacement that can be readily occurred in
It is included within the scope of the present invention.Therefore, protection scope of the present invention with the scope of the claims should be
It is accurate.
