Abstract
The utility model discloses a kind of double-layer composite pipe extruded mould, it is desirable to provide a kind of extruded mould for improving double-layer composite pipe quality.It includes the core rod that die body is located in the die body；Die body is by shell（1）, die sleeve（2）, shaping cover（15）And material extrusion orifice plate（7）Constitute, core rod is by current divider bearing（6）, current divider（8）, separation sleeve（10）And plug（12）Constitute；Die sleeve（2）With separation sleeve（10）Between formed outer layer runner（3）, the outer layer runner and be located at shell（1）On injection hole（4）Connection, separation sleeve（10）With plug（12）Between formed internal layer runner（11）, the internal layer runner and current divider bearing（6）On waist-shaped hole（5）Connection.The utility model can not only avoid the plastics tenesmus deformation that hot melt softens, and also improve the adhesion between two layers of plastic；It is a kind of mould for improving two-layer compound extruded pipe quality.
Description
Technical field
The utility model is related to a kind of extrusion molding pipe shaping mould, more particularly to a kind of double-layer composite pipe extruded mould；Belong to
Extruded mould.
Background technology
Two-layer compound extruded pipe is a kind of widely used plastic tube, by two extruderses each by two kinds of different plastics
Extrusion cladding in two-layer compound pipe mold is squeezed into after melting respectively to form.
At present, two-layer compound pipe mold it is generally main by be fixed in shell die sleeve and shaping cover, by current divider branch
Seat is fixed on the composition such as current divider in shell, the separation sleeve being fixed on current divider bearing, the plug being fixed on current divider.By
Melting temperature, hardening by cooling time in two kinds of plastics are differed, when two kinds of plastics of melting are respectively from outer layer runner, internal layer
When being flowed out in runner, even if being also difficult to hardening by cooling, internal layer or outer layer plastic meeting simultaneously under the forced cooling of cooling and shaping pipe
Because being dropped self gravitation and；The deformation of finished plastic pipe, circularity and linearity are not only resulted in and does not reach requirement, and can cause two
Combined strength bination between layer plastics declines, causes two layers of plastic to separate, and influences product service life.
The content of the invention
In order to overcome defect present in prior art, the utility model aims to provide a kind of pair for improving pipe workpiece quality
Layer multiple tube extruded mould.
To achieve these goals, the utility model uses following technical scheme：It includes die body and is located in the die body
Core rod；The die body by shell, the die sleeve being fixed in the shell and shaping cover, be fixed on the material extrusion orifice plate structure at housing entry end
Into the core rod is by the current divider bearing being fixed in shell, the current divider being fixed in the current divider bearing, in die sleeve
And be fixed on current divider bearing separation sleeve, in the separation sleeve and be fixed on the plug on current divider composition；Die sleeve with
Gap between separation sleeve forms outer layer runner, the outer layer runner and connected with the injection hole being located on shell, separation sleeve and plug
Between gap form internal layer runner, the internal layer runner and connected with the waist-shaped hole on current divider bearing.
Plug has with the inside of current divider is fixed with shower nozzle at the air passage outlet in the air flue connected, plug；It is located at shell
On air admission hole connected through current divider bearing with the air flue in current divider；The jet-impingement direction of shower nozzle is obliquely directed towards sizing
The inwall of set.
Compared with the prior art, the utility model by adopting the above-described technical solution, added in core rod air flue and
Shower nozzle；Therefore expansion sizing can be carried out to not yet cooling tubing by compressed air, add composite pressure, can not only kept away
Exempt from the plastics tenesmus deformation of hot melt softening, ensure that the circularity and linearity of tubing, but also ectonexine plastics can be made simultaneously cold
But the adhesion between two layers of plastic, is improved.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A-A sectional views in Fig. 1.
In figure：Shell 1, die sleeve 2, outer layer runner 3, injection hole 4, waist-shaped hole 5, current divider bearing 6, material extrusion orifice plate 7, shunting
Device 8, air admission hole 9, separation sleeve 10, internal layer runner 11, plug 12, air flue 13, shower nozzle 14, shaping cover 15.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As shown in Fig. 1~2：Die body is by shell 1, the die sleeve being threadedly secured in the shell 2 and shaping cover 15, fixation
Constituted in the material extrusion orifice plate 7 of the arrival end of shell 1, core rod by be threadedly secured in shell 1 current divider bearing 6, by spiral shell
Current divider 8 that line is fixed in the current divider bearing, in die sleeve 2 and be threadedly secured on current divider bearing 6 every
From set 10, in the separation sleeve and the plug 12 that is threadedly secured on current divider 8 is constituted.Die sleeve 2 and separation sleeve 10 it
Between gap formed circular cone loop configuration outer layer runner 3, shell 1, die sleeve 2, current divider bearing 6 and separation sleeve 10 enclose jointly
Into the cavity volume of an annular groove shape, the injection hole 4 being located on shell 1 is connected by the cavity volume with outer layer runner 3；Separation sleeve 10 and core
Three waist-shaped holes 5 that gap between rod 12 is formed on internal layer runner 11, the internal layer runner and the current divider bearing 6 of annular connect
It is logical.
In order to avoid pipe deformations, and also to improve the adhesion of layer materials, in plug 12 and current divider 8
The air flue 13 of connection is internally provided with, the exit of air flue 13 inside plug 12 is fixed with shower nozzle 14；It is located on shell 1
Air admission hole 9 is connected through current divider bearing 6 with the air flue 13 in current divider 8.
In order to ensure expansion effect, the jet-impingement direction of shower nozzle 14 is obliquely directed towards the inwall of shaping cover 15.Work as compression
When air sprays from shower nozzle 14, the tubing not yet cooled down completely just can be made to expand and fit in the inwall of shaping cover 15 completely,
Avoid it from dropping；Not only the circularity and linearity of tubing ensure that but also tubing can have been made quickly to cool down.
