Concrete, described the first annular through groove comprises import department, transition part and the forming part that sets gradually, and import department's groove width is greater than the forming part groove width, the descending setting of transition part groove width.
The radical length of described the first annular through groove import department is greater than the radical length of forming part, and the transition part radical length diminishes gradually from import department to forming part.
The groove width of described the first annular through groove forming part equates with the groove width of the second annular through groove.
The described external mold place of keeping to the side arranges several the first connecting holes.
Described the first annular through groove port of export external mold end is provided with annular groove, and mouthful mould is provided with the flange collar with this annular groove coupling, and mouthful mould is connected with external mold is detachable by a circular connector.
The butting section that described circular connector comprises fixed part and is wholely set with fixed part arranges several the second connecting holes on fixed part, the butting section with mouthful mould end against setting.
Described plug is by connector and the first annular through groove port of export internal mold detachable connection of end.
plastic extruder outlet shaped device of the present invention, due to detachable connection of plug that is made with a polytetrafluoroethylmaterial material in the first annular through groove port of export internal mold end, mould is detachable is connected for the mouth that the first annular through groove port of export external mold end and a polytetrafluoroethylmaterial material are made, described plug arranges with a mouthful mould coupling and forms the second annular through groove, and the plug that is made by polytetrafluoroethylmaterial material and a mouthful mould not only can be high temperature resistant, and add and make man-hour the mobility of plastics better, effectively reduced the flow resistance of processing plastic, generate pipe material inner wall and outer wall all smooth, more effectively extended the service life of converted products, product percent of pass reaches more than 95% simultaneously.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the cross-sectional view of plastic extruder outlet shaped device of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 1, plastic extruder outlet shaped device of the present invention, it can comprise internal mold 1 and the external mold 2 that arranges with described internal mold 1 coupling, be provided with the first annular through groove 3 between described internal mold 1 and external mold 2, internal mold 1 end of these the first annular through groove 3 ports of export is with one plug 4 is detachable is connected, external mold 2 ends of first annular through groove 3 ports of export are connected with a bite mould 5 is detachable, described plug 4 arranges with mouthful mould 5 couplings and forms the second annular through groove 6, and described plug 4 all adopts polytetrafluoroethylmaterial material to be made with a mouthful mould 5.the present invention is due to detachable connection of plug 4 that is made with a polytetrafluoroethylmaterial material in the first annular through groove 3 port of export internal mold 1 ends, mould 5 is detachable is connected for the mouth that the first annular through groove 3 port of export external mold 2 ends and a polytetrafluoroethylmaterial material are made, described plug 4 arranges with mouthful mould 5 couplings and forms the second annular through groove 6, and the plug 4 that is made by polytetrafluoroethylmaterial material and a mouthful mould 5 not only can be high temperature resistant, and make the mobility that adds the plastics in man-hour better, effectively reduced the flow resistance of processing plastic, generate pipe material inner wall and outer wall all smooth, more effectively extended the service life of converted products.
Concrete, described the first annular through groove 3 can comprise import department 31, transition part 32 and the forming part 33 that sets gradually, and import department's 31 groove widths are greater than forming part 33 groove widths, the transition part 32 descending settings of groove width.Processing plastic flow to after import department 31 comes in the process of forming part 33, due to the effect of transition part 32, makes like this processing plastic flow more steady, simultaneously the processing plastic flow velocity is accelerated gradually.
