Abstract
The invention relates to a pipe extruding mold, which comprises a feeding mold, wherein a feeding opening and an annular groove are formed on the feeding mold; when fed, raw materials enter the annular groove from the feeding opening; and the discharge end face of the annular groove has at least two discharge holes. When the pipe extruding mold is used, through the improvement on the discharge holes on the feeding mold and increasing some design for effectively controlling the thickness of pipes, the thicknesses of the pipes produced are very uniform, production efficiency is greatly improved, and time and labor are saved.
Description
Technical field
The present invention relates to a kind of tubing extrusion die.
Background technology
A lot of tubing extrusion dies are arranged in the market, can process the tubing that various mono-layer tubes, bimetallic tube etc. are applied to every field.Total institute is known, and the control for tube wall thickness in the time of processing tubing is even more important, and the tube wall thickness that much processes is uneven, has a strong impact on its performance.In order to control the wall thickness of tubing better, a lot of manufacturers all are regularly the tubing that section inspection processes, and find that wall unevenness is even, adjust from mould again, and so forth, had a strong impact on production efficiency, and tubing itself also only had to the improvement on the not half, this point is far from being enough, therefore, must improve from the tubing extrusion die, overcome the defective in the original production, enhance productivity.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the problem that existing tubing extrusion die exists in the above-mentioned background technology, provide a kind of improved tubing extrusion die.
The technical solution adopted in the present invention is: a kind of tubing extrusion die, comprise that one offers the charging mould of annular groove, charging mould center of inside is provided with plug, also be provided with package cover on the described charging mould, form a toroidal cavity between package cover and the annular groove, also be provided with charging aperture on the described package cover, raw material enters toroidal cavity by charging aperture during charging, the discharging end face of described charging mould is provided with at least two discharge openings that are communicated with described toroidal cavity, the pore size of discharge opening be according to discharge opening apart from the distance of charging aperture from the near to the remote rule and increase progressively gradually, during discharging, the raw material in the toroidal cavity outwards flows out by discharge opening.
Further, the discharging end face of annular groove of the present invention is provided with at least four discharge openings that distribute symmetrically and evenly.
Further, the pore size of discharge opening of the present invention be according to discharge opening from the distance of charging aperture from the near to the remote rule and increase progressively gradually, because it is more big near the material flow the discharge opening of charging aperture close to more, flow near the raw material discharge opening of charging aperture away from more is more little, so such design could guarantee that the material flow size that each discharge opening comes out is identical as much as possible, could guarantee that the wall thickness that processes tubing reaches even.
Further, discharging end face outer setting of the present invention has and discharging end face all-in-one-piece cambered surface buffering slope, cambered surface cushions sloping central authorities and is provided with taper punishment in advance port, cambered surface buffering slope can be played the effect of buffering to the raw material that comes out in the discharge opening, can enough slowly enter the punishment in advance port along cambered surface, further control the even of material flow.
Further, in order to control the tubing of tube wall thickness and processing different inner diameters better, charging mould of the present invention is socketed with water conservancy diversion mould and plug die successively by plug.
The invention has the beneficial effects as follows: tubing extrusion die of the present invention is by to the improvement in charging mould top discharge hole and increased some and can effectively control the tubing design of Wall Thickness, make that not only the tube wall thickness that processes is very even, and improved production efficiency greatly, time saving and energy saving.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the preferred embodiments of the present invention;
Fig. 2 is the structure distribution schematic diagram in charging mould top discharge of the present invention hole.
Among the figure: 1. charging mould, 2. charging aperture, 3. annular groove, 4. discharging end face, 5. discharge opening, 6. cambered surface buffering slope, 7. punishment in advance port, 8. plug, 9. package cover.
The specific embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As Fig. 1, the embodiment of tubing extrusion die of the present invention shown in Figure 2, comprise that one offers the charging mould 1 of annular groove 3, charging mould 1 center of inside is provided with plug 8, also be provided with package cover 9 on the described charging mould 1, form a toroidal cavity between package cover 9 and the annular groove 3, also be provided with charging aperture 2 on the described package cover 9, the discharging end face 4 of charging mould 1 is provided with 12 symmetries and equally distributed discharge opening 5, be less than from the aperture of the discharge opening 5 of charging aperture 2 away from more from the aperture of the discharge opening 5 of charging aperture 2 close to more, discharging end face 4 outer setting have and discharging end face 4 all-in-one-piece cambered surfaces buffering slope 6, cambered surface cushions sloping 6 central authorities and is provided with taper punishment in advance port 7, and plug 8 runs through punishment in advance port 7.In order to reach better effect, can also socket water conservancy diversion mould and plug die on the described charging mould 1.
Raw material enters toroidal cavity by charging aperture 2, then evenly outwards flow out in 12 discharge openings 5 from the discharging end face 4, by slowly flowing to discharging port 7 after 6 bufferings of cambered surface buffering slope, enter the uniformity coefficient that the water conservancy diversion mould is further stablized raw material again, pass through plug die at last.
Just the specific embodiment of the present invention of describing in the above specification, various not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field after having read specification can to before the described specific embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
