Description
Technical field
Pp powder special twin screws are the utility model is related to, belong to screw technique field.
Background technology
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 screw head of the pp powder special twin screws of prior art can be moved rearwardly away from the note of barrel with screw body
Discharging opening is moulded, during this, because screw head is away from the injection discharging opening of barrel so that during discharging, barrel front end
Material can not be stirred so that injection effect it is bad, easily make to produce bubble in product.In order to solve above-mentioned difficulties, need
Develop a when screw head is moved rearwardly away from the injection discharging opening of barrel with screw body, the material of barrel front end is still
The pp powder special twin screws that can be stirred.
The content of the invention
The purpose of this utility model is to provide pp powder special twin screws.
Problem to be solved in the utility model is the screw head of prior art twin-screw as screw body is moved rearwardly away from
During the injection discharging opening of barrel, the problem of material of barrel front end can not obtain stirring.
To realize the purpose of this utility model, the technical solution adopted in the utility model is：
Pp powder special twin screws, including it is screw body, the first spiral shell rib, stirring ring, bearing, tailstock, steel ball, puddler, close
Seal, spring, groove, screw head and the second spiral shell rib, bearing is each side installed in the tailstock, screw body lower end is arranged on
In bearing, screw body is externally provided with more than one the first spiral shell rib, and the first spiral shell rib is each side provided with stirring ring, stirs and is set on ring
There are more than one the second spiral shell rib, screw body front end installation screw head, the interior left and right sides of screw head is respectively provided with groove, installed in groove
Spring, puddler is installed on spring, puddler front end is stretched out outside groove, installs sealing ring at slot opening between puddler.
The puddler upper end is installed by steel ball.
The utility model has the advantages that：In stirring mix stage, screw head is located at barrel front end, and steel ball is contradicted in barrel
In side wall, compression spring, make puddler lower end more in groove；Sealing ring is avoided that material is entered in groove, son
Head with screw body rotate when, puddler also with screw body rotate；In injection discharging stage, screw body, which is rotating, to be moved rearwards
Away from barrel injection discharging opening when, screw head is moved rearwards also with screw body, puddler spring restoring force effect under,
Eject forward, more puddlers is removed outside groove, puddler left end is made barrel between barrel front end and screw head
The material of front end can still be stirred so that injection effect is good, will not make to produce bubble in product；Stirring ring can make to be molded
More preferably, the product quality being molded by is high, does not have bubble for journey adequacy, uniformity.
Brief description of the drawings
Fig. 1 is the utility model pp powder special twin screw overall structure figures；
Fig. 2 is the enlarged diagram of a portions structure；
Fig. 3 is the enlarged diagram of b portions structure；
In figure：1st, screw body 2, the first spiral shell rib 3, stirring ring 4, bearing 5, tailstock 6, steel ball 7, puddler
8th, sealing ring 9, spring 10, groove 11, screw head 12, the second spiral shell rib.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model.
The utility model pp powder special twin screws, including screw body 1, the first spiral shell rib 2, stirring ring 3, bearing 4, tailstock 5,
Steel ball 6, puddler 7, sealing ring 8, spring 9, groove 10, the spiral shell rib 12 of screw head 11 and second, in the tailstock 5 each side
Bearing 4 is installed, the lower end of screw body 1 is arranged in bearing 4, and screw body 1 is externally provided with the first spiral shell of more than one rib 2, and the first spiral shell rib 2 is left
Right both sides are respectively provided with stirring ring 3, and stirring ring 3 is provided with the second spiral shell of more than one rib 12, and stirring ring 3 can make injection moulding process abundant
Property, uniformity more preferably, the product quality that is molded by is high, does not have bubble, the front end of screw body 1 installation screw head 11, screw head 11
The interior left and right sides is respectively provided with groove 10, and spring 9 is installed in groove 10, puddler 7 is installed on spring 9, the front end of puddler 7 is stretched out recessed
Outside groove 10, sealing ring 8 is installed between the opening of groove 10 and puddler 7, the upper end of puddler 7 installation steel ball 6, rank is kneaded in stirring
Section, screw head 11 are located at barrel front end, and steel ball 6 is contradicted on barrel madial wall, compression spring 9, makes the lower end of puddler 7 more
In groove 10；Sealing ring 8 is avoided that material is entered in groove 10, subheader with screw body 1 rotate when, puddler 7
As screw body 1 rotates；In injection discharging stage, when screw body 1 is rotating the injection discharging opening for being moved rearwardly away from barrel, spiral shell
Head 11 is moved rearwards also with screw body 1, and puddler 7 ejects forward under the restoring force effect of spring 9, makes more to stir
Mix bar 7 to remove outside groove 10, the left end of puddler 7 is made the material of barrel front end still between barrel front end and screw head 11
It is old to be stirred so that injection effect is good, will not make to produce bubble in product.
The utility model application method：In stirring mix stage, screw head 11 is located at barrel front end, and steel ball 6, which contradicts, is expecting
In medial wall of the tube, compression spring 9, make the lower end of puddler 7 more in groove 10；Sealing ring 8 is avoided that material enters
In groove 10, subheader with screw body 1 rotate when, puddler 7 rotates also with screw body 1；In injection discharging stage, screw body
1 when being rotating the injection discharging opening for being moved rearwardly away from barrel, and screw head 11 is moved rearwards also with screw body 1, and puddler 7 exists
Under the restoring force effect of spring 9, eject forward, more puddlers 7 is removed outside groove 10, make the left end of puddler 7 positioned at material
Between cylinder front end and screw head 11, make the material of barrel front end can still be stirred so that injection effect is good, will not make product
Middle generation bubble；Stirring ring 3 can make injection moulding process adequacy, uniformity more preferably, and the product quality being molded by is high, does not have gas
Bubble.
