Description
Technical field
The utility model relates to parallel incongruous double screws, belong to screw technique field.
Background technique
Screw rod outer surface cuts with the cylinder of helicla flute or cuts with the circular cone of Conical Spiral Groove, and screw rod is injection molding apparatus
Core component, the spiral shell rib structure in the screw body of the parallel incongruous double screw of the prior art is all excessively single, so that being molded by
During material, injection molding effect is bad, is easy to make to generate bubble in discharging product.In order to solve the above difficulties, it needs to develop a
Spiral shell rib structure diversification in screw body does not generate the parallel incongruous double screw of bubble in the product that discharges.
Summary of the invention
The purpose of the utility model is to provide parallel incongruous double screws.
Problem to be solved in the utility model is the spiral shell rib structure in the screw body of the parallel incongruous double screw of the prior art
All excessively single problems.
To realize the purpose of this utility model, the technical solution adopted in the utility model is:
Parallel incongruous double screw, including third screw body, the second screw body, stirring ball, fin, screw head, the first screw rod
Body, the first spiral shell rib erect rib, the second spiral shell rib, screw shaft, bearing and saddle, each side install bearing, screw rod on the saddle
First screw body is respectively installed, the first screw body upper end is equipped with the first spiral shell rib from top to bottom, in the first screw body of the left and right sides on axis
The first spiral shell rib be opposite direction setting, multiple perpendicular ribs are equipped in the middle part of the first screw body, the first screw body lower end is equipped with from top to bottom
Second spiral shell rib, the second spiral shell rib in the first screw body of the left and right sides are opposite direction setting, are the second screw rod at the top of the first screw body
Body, the second screw body left and right sides are respectively provided with third screw body, are screw head above the second screw body, screw head surrounding is respectively installed
There is fin, is stirring ball at the top of screw head.
Diameter of the diameter of second screw body less than the first screw body.
The utility model has the advantages that: fin plays the role of stirring the material of barrel front end, so that injection molding effect is good,
It will not make to generate bubble in product；Third screw body will play the role of stirring and tearing to material, so that injection molding effect is good, energy
The bubble in material is removed, makes do not have bubble in the product of discharging.
Detailed description of the invention
Fig. 1 is the parallel incongruous double screw overall structure figure of the utility model；
Fig. 2 is the top view of the second screw body；
Fig. 3 is the top view of fin；
Fig. 4 is the top view of perpendicular rib；
In figure: 1, third screw body 2, the second screw body 3, stirring ball 4, fin 5, screw head 6, the first spiral shell
The body of rod 7, the first spiral shell rib 8, perpendicular rib 9, the second spiral shell rib 10, screw shaft 11, bearing 12, saddle.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
The parallel incongruous double screw of the utility model, including third screw body 1, the second screw body 2, stirring ball 3, fin 4, spiral shell
Head 5, the first screw body 6, the first spiral shell rib 7, perpendicular rib 8, the second spiral shell rib 9, screw shaft 10, bearing 11 and saddle, on the saddle
Bearing 11 is each side installed, first screw body 6 is respectively installed on screw shaft 10,6 upper end of the first screw body is equipped with from top to bottom
First spiral shell rib 7, the first spiral shell rib 7 in the first screw body of the left and right sides 6 are opposite direction setting, are equipped in the middle part of the first screw body 6 more
A perpendicular rib 8,6 lower end of the first screw body are equipped with the second spiral shell rib 9, the second spiral shell rib 9 in the first screw body of the left and right sides 6 from top to bottom
It is arranged for opposite direction, is the second screw body 2 at the top of the first screw body 6, is respectively provided with third screw body at left and right sides of the second screw body 2
1, it is screw head 5 above the second screw body 2, it is stirring ball 3 at the top of screw head 5 that 5 surrounding of screw head, which is respectively equipped with fin 4, second
For the diameter of screw body 2 less than the diameter of the first screw body 6, the second screw body 2 and the first screw body 6 be integrated cutting forming,
Stirring ball 3 is hemispherical dome structure.
The utility model application method: fin 4 plays the role of stirring the material of barrel front end, so that injection molding effect
It is good, it will not make to generate bubble in product；Third screw body 1 will play the role of stirring and tearing to material, so that injection molding effect
It is good, the bubble in material can be removed, makes do not have bubble in the product of discharging.
