Abstract
The utility model discloses a kind of bridge insert for plastic irregular profile mould, include the bridge insert of cylinder, the cylindrical bridge insert includes being provided with multilayer concentric circular hole passage in the spout and the sleeve-board being socketed on the outside of spout positioned at the center of circle, the spout；It is centrally located for put-through channel in the concentric circle holes passage, on the outside of center for oblique circulation passage, oblique circulation passage cross-like each other.The combination of the utility model density, tactical rule, design processing are simple, while not influenceing extruder to extrude flow, strengthen the plasticizing of the material at wall, larger can improve the apparent mass and cold punching performance of extrusion plastic section bar.
Description
Technical field
The utility model is related to plastic irregular profile and makes field, more particularly to one kind can promote material fully to plastify fusion
Extruder and mould interface connection device.
Background technology
The one of which key factor for influenceing plastic profile extrusion shaping is exactly plastifying state of the material when going out die head,
Traditional structure is that extruder is sheared to material plasticizing by spiral, builds after pressure and extrudes into die head.Due to present profile shapes
Extruded velocity is universal higher, while being formulated the increase of inserts ratio, often appearance plasticizing is not enough, has spiro rod plasticizing in Surface of profile
Memory trace, has had a strong impact on the combination property of section bar.The method generally handled is increase die head length, by increasing die pressure
To solve, but because pressure is bigger than normal, make the problems such as jaundice, aberration occurs in Surface of profile；Or increase between die head and stock mould
Orifice plate is added, porous plate uses concentric through state, it can make material become linear pattern from helical form, but can not solve outer
The plasticizing memory of layer material；Also helical blade type transition ring structure, but due to processed complex, polishing is difficult, processing space limit
System, hardly results in larger area popularization and application.
Utility model content
The purpose of this utility model is that there is provided a kind of mixed flow for plastic irregular profile mould for solution the deficiencies in the prior art
Plate so that material further obtains pressurization plasticizing when by bridge insert.Particularly outer skin materials, obtain intersecting and are mixed to mixing
Stream, eliminates the original-party tropism of Screw Extrusion stream, plasticizing is more become uniform and stable, effectively improves the apparent matter of plastic material
Amount and cold punching performance.
The technical solution adopted in the utility model is：A kind of bridge insert for plastic irregular profile mould, including cylinder
Bridge insert, the cylindrical bridge insert includes the spout and the sleeve-board that is socketed on the outside of spout positioned at the center of circle, the spout
It is interior to be provided with multilayer concentric circular hole passage；It is centrally located for put-through channel in the concentric circle holes passage, on the outside of center
For oblique circulation passage, oblique circulation passage cross-like each other.
As further improvement of the utility model, the oblique circulation passage is two layers.
The utility model use beneficial effect be：The bridge insert material of this structure after extruder by occurring spiral squeezing
Afterwards, into bridge insert concentric circle holes passage, linear motion is changed into by screw by paracentral stream；Close to the material of outer layer
While stream changes into linear motion by screw, crossed longitudinally mixing also there occurs.When stream by bridge insert enters die head
When, the flow regime of material becomes orderly, becomes more closely knit after material pressurization, while being eliminated after outer skin materials cross-mixing certainly
Stream traces of memory formed by screw rod rotation, makes the plasticizing of material reach full and uniform soft, improves material and enter die head
When plasticizing effect.The combination of the utility model density, tactical rule, design processing are simple, and flow is extruded not influenceing extruder
While, the plasticizing of the material at wall is strengthened, the apparent mass and cold punching performance of extrusion plastic section bar larger can be improved.
Brief description of the drawings
Fig. 1 is the utility model use state schematic diagram.
Fig. 2 is the utility model schematic diagram.
Fig. 3 is the utility model sectional view.
Shown in figure：1 bridge insert, 2 transition sleeves, 3 extruders, 4 mould flanges, 5 die head machine necks, 6 double-threaded screws
And nut, 11 sleeve-boards, 12 spouts, 13 oblique circulation passages, 14 put-through channels.
Embodiment
With reference to Fig. 1 to Fig. 3, the utility model is described further.
As illustrated, a kind of bridge insert for plastic irregular profile mould, includes the bridge insert 1 of cylinder, the cylinder
The bridge insert 1 of shape is included in the spout 12 and the sleeve-board 11 for being socketed in the outside of spout 12 positioned at the center of circle, the spout 12 provided with many
Layer concentric circle holes passage；Centrally located for put-through channel 14 in the concentric circle holes passage, on the outside of center is oblique
Circulation passage 13, the oblique circulation passage 13 cross-like each other.
Bridge insert 1 is circular slab, and circular slab center is placed with multilayer concentric circular hole passage, wherein the multilayer positioned at center is justified
Hole is put-through channel, and peripherally located two layers of circular hole is oblique circulation passage, and the put-through channel of internal layer is wrapped in by the oblique circulation passage of outer layer
Inside, while the oblique circulation passage of outer layer cross-like each other.
Bridge insert 1 is arranged on transition sleeve 2 and the positioning of die head machine neck 5 is sunk in platform, transition sleeve 2 and the port of export phase of extruder 3
Even, die head machine neck 5 is connected with mould flange 4, and mould flange 4 is fastened with extruder 3 by stud nut 6.
To ensure using effect of the present utility model, eliminate from stream traces of memory formed by screw rod rotation, make thing
The plasticizing of material reach it is full and uniform soft, improve material into die head when plasticizing effect, the oblique circulation passage be two layers, mutually
For cross-like.
Bridge insert is arranged between outlet of extruder and die entrance, and two ends positioning, bridge insert are carried out by the heavy platform of circle
There is multilayer concentric circular hole passage centre, and material after extruder by occurring after spiral squeezing, into bridge insert concentric circle holes passage,
Linear motion is changed into by spiral by paracentral stream；While linear motion being changed into close to the stream of outer layer by spiral,
Crossed longitudinally mixing is also there occurs, when stream enters die head by bridge insert, the flow regime of material becomes orderly, material pressurization
After become more closely knit, while eliminated after outer skin materials cross-mixing from screw rod rotation formed by stream traces of memory, make thing
The plasticizing of material reach it is full and uniform soft, improve material into die head when plasticizing effect.The utility model density is combined, knot
Structure rule, design processing are simple, while not influenceing extruder to extrude flow, strengthen the plasticizing of the material at wall,
It larger can improve the apparent mass and cold punching performance of extrusion plastic section bar.
Those skilled in the art may be used also it is to be understood that protection scheme of the present utility model is not limited only to the above embodiments
To carry out various permutation and combination and conversion on the basis of above-described embodiment, on the premise of without prejudice to the utility model spirit,
The various conversion that the utility model is carried out are all fallen within protection domain of the present utility model.
