The utility model discloses beneficial effect such as to improve PE tubular product smooth finish, change convenience, adaptable different model tubular product have.
Description
Technical field
This utility model belongs to PE tube extrusion die manufacturing technology field, is specifically related to a kind of extrusion die device produced for PE pipe.
Background technology
The effect of PE pipe extrusion die be the PE fused mass making extruder extrude uniformly across whole mould section, make PE fused mass formed continuous print tubing.The mould of prior art is made up of mouth die, core, heater, die supports and mold etc., PE stream is to be extruded machine extrusion molding by the extrusion channel between mouth die and core, therefore the fineness of PE product surface is determined by the fineness of die face, if the fineness of mould is bad, tiny male and fomale(M&F) will make the fineness of goods be deteriorated.Produce the commonly used metal material of extrusion die of PE extruding pipe material at present, during high temperature production, the die head mouth inevitably adhesion extrusion melt of steel die, time one long melt will be carbonized, hardening, the metal covering on die orifice top layer and internal layer is lived in adhesion, the outer wall making PE extruding pipe material produces cut, affects the fineness of tubing.
Utility model content
For deficiencies of the prior art, the purpose of this utility model be to provide a kind of can improve PE tubing fineness and also change conveniently, be suitable for the extrusion die device of different model tubing.
The purpose of this utility model is achieved through the following technical solutions: a kind of extrusion die device produced for PE pipe, including extrusion head die sleeve, core and squeezing passage, it is characterized in that: also include gland and politef set, described gland is cylindrical, inside having through hole, gland end face to be provided with small through hole, described politef set is horizontal cylinder boss shape, through hole, the external diameter of the little round platform in the politef set left side is inside had to close with the diameter compatible of gland；On the right of politef set, the external diameter of big round platform is consistent with the external diameter of gland, also the small through hole corresponding with gland end face is offered on the end face of big round platform on the right of politef set, described extrusion head die sleeve is cylindrical, inside there is through hole, the through hole on the right is bell mouth shape, the through hole internal diameter on the left side is consistent with the internal diameter of politef set through hole, extrusion head die sleeve end face is provided with a hole, described gland and politef set and is interconnected with extrusion head die sleeve by screw, silk hole and small through hole.
Compared with prior art, this utility model has had the advantage that: have politef set owing to connecting on extrusion head die sleeve end face, and the external diameter of the little round platform in the politef set left side closes with the diameter compatible of gland；On the right of politef set, the external diameter of big round platform is consistent with the external diameter of gland, thus make PE stream when by extrusion channel between extrusion head die sleeve and core, at the die head port of export, the outer wall of PE tubing just contacts with politef set, rather than contact with metal mouth die, owing to the fineness of politef is higher, and being difficult to be stained with melt, the fineness of the PE pipe outer surface therefore extruded is preferable.Owing to being provided with a hole by the small through hole corresponding with on gland end face and extrusion head die sleeve end face on screw, the small through hole of gland end face, politef set end face, just gland and politef can be overlapped and interconnect with extrusion head die sleeve, therefore, when politef set needs cleaning and changes, operation is convenient to.But also gland and the politef set of different model according to different tubing models, can be changed, therefore the scope of application is wider.

Detailed description of the invention
As Figure 1-3, a kind of extrusion die device produced for PE pipe, including extrusion head die sleeve, core, gland and politef set, described gland is cylindrical, inside having through hole, gland end face to be provided with 6 small through hole, described politef set is horizontal cylinder boss shape, inside having through hole, the external diameter of the little round platform in the left side closes with the diameter compatible of gland；The external diameter of the big round platform in the right is consistent with the external diameter of gland, and the end face of the big round platform in the right also offers 6 small through hole, and the most corresponding with 6 small through hole on gland end face.Described extrusion head die sleeve is cylindrical, inside there is through hole, the through hole on the right is bell mouth shape, the through hole internal diameter on the left side is consistent with the internal diameter of politef set through hole, described extrusion head die sleeve end face is provided with a hole, described gland and politef set and is linked together with extrusion head die sleeve by screw, silk hole and small through hole.
The core left side described in the utility model is cylindrical, and the right is coniform, and the end face on the core left side is provided with spanner, and the end face on the right is provided with screw, and core is connected with screw extruder by screw.
Squeezing passage described in the utility model is core gap when overlapping with extrusion head die sleeve through politef, between core external diameter and politef set and the internal diameter of extrusion head die sleeve.
