Description
Technical field
The invention belongs to tubular object extruding equipment technical field, be specifically related to a kind of extruder increasing tube surfaces fineness
Die head.
Background technology
Extruder is that basic classification is double screw extruder by equipment extruded for product shape as required, single
Screw extruder and rare multi-screw extruder and elastirotor extruder. existing extruder either single screw rod is still
Twin screw, screw extruder is dependent on screw rod and rotates the pressure and shearing force produced, material can be made fully to plastify
And uniformly mix, by mouth die molding.
The working mechanism of screw-type extruder is dependent on screw rod and rotates produced pressure and shearing force, can make the material can
Fully to carry out plastifying and uniformly mixing, by mouth die molding；So sometimes use an extruder just can complete simultaneously
Mixing, plasticizing and the series of process such as molding, thus carry out continuous print production.In addition the working mechanism master of plunger-type extruder
If by by circuit die, first complete material will be plastified in advance reach from die extrusion the effect of molding.In material barrel
Material can return in the back-plunger extruded, wait until to add after new round plastifying material followed by the operation energy carrying out next round
It is applicable to mobility extreme difference or the biggest plastics of viscosity, just as the molding of this plastic of Xylonite adds
Work.
In prior art, in the production process of tube forming, easily occur that tube surfaces draws the surfaces such as trace, concave point, pit
The defect of fineness；When equipment is started shooting for a long time, easily occur hanging mould phenomenon, the problem that need to frequently clear up mould；Coating is easy to fall off,
The problem such as must frequently do over again.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides a kind of extruder die head increasing tube surfaces fineness.
A kind of extruder die head increasing tube surfaces fineness, including: core, mouth die and be arranged on described core and institute
Stating the stream road between mouth die, described core is provided with core ring and core pressure ring, and described mouth die is provided with mouth die ring and mouth die
Pressure ring, what described core ring was corresponding with described mouth die ring is arranged on the port of export in described stream road, and described mouth die pressure ring is pressed on
The periphery of described mouth die ring, described core ring is pressed on the periphery of described core pressure ring, and described stream road includes discharging section, centre
Section and feed zone, be provided with the first tetrafluoroethene liner in described mouth die inner circumferential, described core periphery be provided with the second tetrafluoro
Ethylene liner.
Further, described first tetrafluoroethene liner is positioned at described discharging section and the periphery of described interlude.
Further, described second tetrafluoroethene liner is positioned at the periphery of described discharging section.
Further, described mouth die ring is tetrafluoroethene material.
Further, described core ring is tetrafluoroethene material.
Concrete, the outer wall of described mouth die ring is the conical surface, and the inwall of described core ring is the conical surface, described mouth die pressure ring interior
Wall is the conical surface, and the outer wall of described core pressure ring is the conical surface.
Die head provided by the present invention is provided with the extruder of tetrafluoroethene liner can increase tube surfaces fineness, solves
The most now in production process, drawing the defects such as trace, concave point, pit, reducing the phenomenon hanging mould occur in tube surfaces, reduces cleaning mould
Frequency, solves conventional coatings mode simultaneously and holds caducous problem, and it is simple and reasonable, extruding pipe material smooth surface.
Accompanying drawing explanation
Fig. 1 is the sectional view of the extruder die head of increase tube surfaces fineness provided by the present invention.
In accompanying drawing 1, the list of parts representated by each label is as follows:
1, core, 2, mouth die, 3, stream road, 301, discharging section, 302, interlude, 303, feed zone, 4, core ring, 5, core
Mold ring, 6, mouth die ring, 7, mouth die pressure ring, the 8, first tetrafluoroethene liner, the 9, second tetrafluoroethene liner.
Detailed description of the invention
Principle and feature to the present invention are described below, and illustrated embodiment is served only for explaining the present invention, is not intended to
Limit the scope of the present invention.
In a detailed description of the invention, as it is shown in figure 1, a kind of extruder die head increasing tube surfaces fineness, bag
Include: core 1, mouth die 2 and the stream road 3 being arranged between core 1 and mouth die 2.
Core 1 is provided with core ring 4 and core pressure ring 5, and core ring 4 is tetrafluoroethene material.Mouth die 2 is provided with mouth die ring
6 and mouth die pressure ring 7, mouth die ring 6 is tetrafluoroethene material.Core ring 4 and the outlet being arranged on stream road 3 of mouth die ring 6 correspondence
End, mouth die pressure ring 7 is pressed on the periphery of mouth die ring 6, and core ring 4 is pressed on the periphery of core pressure ring 5, and stream road 3 includes discharging
