Abstract

The utility model belongs to the technical field of the extruder, concretely relates to aircraft nose is extruded to PEEK rod, PEEK raw materials in proper order through screw rod chamber head, go out to water board, bush board and setting mould and by extrusion moulding, be equipped with the flange between bush board and the qualitative mould, screw rod chamber head, the inside that goes out to water board, bush board, setting mould and flange are equipped with the passageway of extruding that the PEEK raw materials passes through. The utility model discloses an aircraft nose is extruded to PEEK rod has shortened of PEEK material greatly and has watered the flow, reduced the lay day, effectual avoided the PEEK material because of long -time stop a runner by the degradation problem.

Description

PEEK bar extruder head

Technical field

This utility model belongs to extruder technology field, is specifically related to a kind of PEEK bar extruder head.

Background technology

Polyether-ether-ketone (PEEK) as a kind of novel special engineering plastics, have outstanding physics, Mechanical property, can become the most popular with the traditional material such as alternative metals, pottery at many special dimensions One of high performance engineering plastics.PEEK resistance to elevated temperatures is the most prominent, can at 260 DEG C life-time service, Moment uses temperature up to 315 DEG C；Its rigidity is big, and dimensional stability is high, and linear expansion coefficient is less；PEEKization Learn good stability, the almost all of organic solvents such as acid, alkali are had the strongest resistance to corrosion, has simultaneously There are the performances such as fire-retardant, radioprotective；The resistance to skimming wear of PEEK and the excellent performance of fretting wear consumption.By these Excellent combination property, PEEK leads in Aero-Space, machinery, oil, chemical industry, nuclear power, track traffic etc. Territory is all widely used, even if in 200 DEG C of steams, its physical property does not the most occur significantly to change, and can grow Phase uses.

PEEK is thermoplasticity special plastic, aborning, according to the needs of different clients, uses different one-tenth Type mode, common are injection, extrude, mold pressing etc..For the product needed of some seriality sizes, past Toward extrusion molding to be used.

PEEK extruder principle and Other Engineering plastics, such as: PA66 (nylon66 fiber), PPS (polyphenyl Thioether), the extruder such as PVDF (Kynoar), PSU (polysulfones) be similar to, simply the squeezing of PEEK Go out that forming temperature is high, poor fluidity, generally require and improve screw size, select special screw rod material, choosing Selecting higher ceramic heat circle, it is the most out in the cold that the head of extruder goes out to water place.

Utility model content

The purpose of this utility model is to provide a kind of PEEK bar extruder head, substantially reduces PEEK material That expects goes out to water flow process, decreases the lay day, effectively avoids PEEK material because resting on out for a long time Cast gate and the problem that is degraded.

For achieving the above object, this utility model the technical scheme is that PEEK raw material sequentially passes through spiral shell Bar chamber head, go out to water plate, mouth template and shaping mould and be extruded, be provided with between mouth template and shaping mould Flange, screw rod chamber head, goes out to water the inside of plate, mouth template, shaping mould and flange and is provided with PEEK raw material and leads to The extrusion passage crossed.

Preferably, described extrusion passage is provided with a necking down at the link position going out to water plate and mouth template.

Preferably, on the head of described screw rod chamber with go out to water the position that plate is connected and be provided with external screw thread, go out to water on plate with spiral shell The position that bar chamber head connects is provided with female thread, and screw rod chamber head is spirally connected with going out to water plate.

Preferably, go out to water described in and fixed by many group countersunk head screws between plate, mouth template and flange.

Preferably, the group number of described countersunk head screw is 4-6 group.

After using technique scheme, this utility model has the positive effect that:

The shortening that the assurance needs of the factors such as the viscosity of PEEK, mobility, temperature are tried one's best in forming process is not Necessary flow distance, shortens the material for making clothes time of staying in stream chamber, reduces the high temperature degradation of material for making clothes.This practicality PEEK bar extruder head assembly in novel is few, substantially reduces out and waters flow process, decreases the lay day, Effectively avoid PEEK raw material because of that rest on out the cast gate for a long time and problem that is degraded.On extrusion passage There is a necking down, it is simple to extrusion molding.

Accompanying drawing explanation

Fig. 1 is the PEEK bar extruder header structure schematic diagram in this utility model.

Wherein: 1, screw rod chamber head, 2, go out to water plate, 3, mouth template, 4, shaping mould, 5, flange, 6, Extrusion passage, 7, necking down, 8, countersunk head screw.

Detailed description of the invention

With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.

In this utility model, unless otherwise clearly defined and limited, term " install ", " being connected ", " even Connect ", the term such as " fixing " should broadly understood, connect for example, it may be fixing, it is also possible to be detachable Connect, or integral；Can be to be mechanically connected, it is also possible to be electrical connection；Can be to be joined directly together, it is possible to To be indirectly connected to by intermediary, can be connection or the interaction of two elements of two element internals Relation.For the ordinary skill in the art, can understand that above-mentioned term is at this as the case may be Concrete meaning in utility model.

As it is shown in figure 1, be PEEK bar extruder head of the present utility model, PEEK raw material sequentially passes through spiral shell Bar chamber 1, go out to water plate 2, mouth template 3 and shaping mould 4 and be extruded, mouth template 3 and shaping mould Flange 5 it is provided with between 4.Screw rod chamber 1, go out to water the interior of plate 2, mouth template 3, shaping mould 4 and flange 5 Portion is provided with is easy to the extrusion passage 6 that PEEK raw material passes through, and extrusion passage 6 is going out to water plate 2 and mouth template 3 A necking down 7 it is provided with, it is simple to extrusion molding at link position.

On screw rod chamber 1 with go out to water the position that plate 2 is connected and be provided with external screw thread, go out to water on plate 2 with screw rod chamber 1 The position connected is provided with female thread, screw rod chamber 1 with go out to water plate 2 by external screw thread and coordinating of female thread It is spirally connected.

Go out to water and fixed by many group countersunk head screws 8 between plate 2, mouth template 3 and flange 5.Countersunk head screw 8 Group number can be 4 groups, 5 groups or 6 groups.

PEEK bar extruder head of the present utility model is adapted to the processing to PEEK bar and uses, for The PEEK material of poor fluidity has well extrudes effect.

It will be apparent to those skilled in the art that can technical scheme as described above and design, make it Its various corresponding changes and deformation, and all these changes and deformation all should belong to this practicality newly Within the protection domain that type requires.
