Description

Double-layer composite pipe extruded mould improved structure
Technical field
The present invention relates to a kind of extrusion molding pipe shaping mould, more particularly to a kind of double-layer composite pipe extruded mould improved structure； 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 is formed in clamp-oning two-layer compound pipe mold respectively after melting.
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 current divider in shell, the separation sleeve being fixed on current divider bearing, the plug being fixed on current divider etc. and constitutes.By Differed in two kinds of melt temperatures of plastics, hardening by cooling time, 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 Dropped because of 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.
In addition, for the ease of making a distinction conveying cold flow, the two-layer compound extruded pipe of hot-fluid, it is necessary on the surface of tubing Printed along generatrix direction or coating colour band lines.At present, generally after tubing cooling after individually using a set of independent mould come Complete this work；Therefore have that loosely organized, floor space is big, complex operation, old high many defect.
The content of the invention
In order to overcome defect present in prior art, the present invention is intended to provide a kind of collection extrusion moulding is with application to printed The double-layer composite pipe extruded mould improved structure of one.
To achieve these goals, the present invention uses following technical scheme：It includes core rod of the die body in the die body； The die body is made up of shell, the die sleeve being fixed in the shell and shaping cover, the material extrusion orifice plate for being fixed on housing entry end, institute Core rod is stated by the current divider bearing being fixed in shell, the current divider being fixed in the current divider bearing, in die sleeve and solid The separation sleeve that is scheduled on current divider bearing, in the separation sleeve and it is fixed on the composition of the plug on current divider；Die sleeve with isolate Gap between set forms outer layer runner, the outer layer runner and is connected with the injection hole being located on shell, between separation sleeve and plug Gap form internal layer runner, the internal layer runner and connected with the waist-shaped hole on current divider bearing；Cooling water is fixed with shaping cover Set and colorant refueling nozzle.
Colorant refueling nozzle is four, and is diametrically distributed in the outer circumference surface of shaping cover；On shaping cover port of export edge Generatrix direction is opened in its inwall and groove corresponding with colorant filling mouth position；Plug is connected with the inside of current divider Air flue, be fixed with the air passage outlet in plug jet-impingement direction incline point to shaping cover inwall shower nozzle；It is located at shell On air admission hole connected with the air flue in current divider through current divider bearing.
Compared with the prior art, the present invention in core rod by adopting the above-described technical solution, increased air flue and shower nozzle； Therefore expansion sizing can be carried out to not yet cooling tubing by compressed air, increased composite pressure, can not only avoid heat The molten plastics tenesmus for softening deforms, ensure that the circularity and linearity of tubing, but also can make ectonexine plastics while cooling down, carrying Adhesion between two layers of plastic high.Further, since circulating cooling water jacket and colorant refueling nozzle are increased on shaping cover, because This can not only promote the quick hardening by cooling of two layers of plastic, improve combined strength bination, but also can realize simultaneously in hardening by cooling Tube surfaces application to printed colour band lines.
The present invention forms an entirety due to extrusion moulding mould dexterously being combined with application to printed mould, will Two procedures unite two into one；Therefore can not only reduce occupation area of equipment, reduce equipment investment cost, and also improve equipment Production efficiency, reduce the amount of labour used.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the 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 It is device 8, air admission hole 9, separation sleeve 10, internal layer runner 11, plug 12, air flue 13, shower nozzle 14, colorant refueling nozzle 15, shaping cover 16, cold But water jacket 17, groove 18.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings：
As shown in Fig. 1~2：Die body by shell 1, the die sleeve being threadedly secured in the shell 2 and shaping cover 15, it is fixed outside The material extrusion orifice plate 7 of the arrival end of shell 1 is constituted, core rod by be threadedly secured in shell 1 current divider bearing 6, consolidated by screw thread The current divider 8 that is scheduled in the current divider bearing, in die sleeve 2 and the separation sleeve that is threadedly secured on current divider bearing 6 10th, in the separation sleeve and the plug 12 that is threadedly secured on current divider 8 is constituted.Between die sleeve 2 and separation sleeve 10 Gap forms the outer layer runner 3 of circular cone loop configuration, and shell 1, die sleeve 2, current divider bearing 6 and separation sleeve 10 surround one jointly The cavity volume of individual 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 plug 12 Between gap form the internal layer runner 11 of annular, the internal layer runner connects with three waist-shaped holes 5 on current divider bearing 6.It is fixed Cooling jacket 17 is fixed with the outer circumference surface of jacket 16 and four colorants filling on the surface of shaping cover 16 is diametrically distributed in Mouth 15.
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 for not yet cooling down completely just can be made to expand and fit in the inwall of shaping cover 16 completely, It is avoided to drop；Not only the circularity and linearity of tubing ensure that but also tubing can be made quickly to cool down, while can also can guarantee that coated Colour band lines continuous uniform.
In order to avoid causing colour band lines to obscure because outer pipe wall and shaping cover 16 produce friction, exported in shaping cover 16 End is opened in its inwall and groove 18 corresponding with the position of colorant refueling nozzle 15 along generatrix direction.
