But, because the particularity (mainly comprise talcum powder and calcium carbonate, wherein calcium carbonate accounts for about 90%) of PE modified materials prescription causes the discharge opening of extrusion die very easily to wear and tear in extruding production.
Simultaneously; Because the discharge opening diameter very little (φ 3mm) of extrusion die; The nitration case of discharge opening inwall is more shallow, and the utmost point is not wear-resisting, behind the nitration case of the worn out discharge opening inwall of granulation material; The aperture of discharge opening will become rapidly greatly, thereby causes having only short 15 days (granulation output is about 150 tons) in service life of every mold.
As shown in Figure 1, existing P E modification comminutor supporting extrusion die comprise die ontology 10 and be arranged on the discharge opening 11 on the die ontology; Before use, the aperture of discharge opening 11 is very little, is generally φ 3mm; And after using, it is big that the aperture of discharge opening 11 becomes rapidly, generally at φ 5.5mm.(referring to Fig. 2)
And will wear and tear gradually since the discharge opening diameter of first day extrusion die becomes big, and it is big that the granulation material granularity also progressively becomes, owing to use the inhomogeneous PE modification of this granularity granulation material, just is difficult to guarantee the stay in grade of PE tubing.
In sum, need a kind of modified materials granulation to extrude discharging structure especially, solved the problem of above-mentioned existing existence.
The utility model content
The purpose of the utility model is to provide a kind of modified materials granulation to extrude discharging structure; To the defective that prior art exists, improve the wearability of discharge opening effectively, greatly prolonged the service life of extrusion die; Reduce the time of changing spare part; Reduce operative employee personnel's labour intensity, guaranteed the stable of granulation material quality, reduced cost.
To achieve these goals, the technical scheme of the utility model is following:
Discharging structure is extruded in a kind of modified materials granulation; It comprises the extrusion die body and is arranged on first discharge opening on the said extrusion die body, it is characterized in that, also comprises a discharging extension; Said discharging extension and said extrusion die body are worked in coordination; Said discharging extension is arranged on the front end of first discharge opening of said extrusion die body, and corresponding position with said first discharge opening is provided with second discharge opening, the discharging mouth that is provided with hollow in said second discharge opening and is processed by antifriction alloy on the said discharging extension; Match with said first discharge opening in the rear end of said discharging mouth, the front end of said discharging mouth matches with said second discharge opening.
In an embodiment of the utility model; The aperture of said discharging mouth rear end is not less than the aperture of said first discharge opening; The aperture of said discharging mouth front end is not more than the aperture of said second discharge opening, and the aperture of said discharging mouth rear end is greater than the aperture of said discharging mouth front end.
In an embodiment of the utility model, said discharging mouth is a T type hollow structure, and the rear end of said discharging mouth is greater than the front end of said discharging mouth, and the inboard aperture of said second discharge opening is T type structure and matches with said discharging mouth.
Discharging structure is extruded in the modified materials granulation of the utility model, compares with present product, through increasing the discharging extension and antifriction alloy discharging mouth being set; To improve the wearability of discharge opening, greatly prolonged the service life of extrusion die, reduce the time of changing spare part; Reduced operative employee personnel's labour intensity; Guarantee the stable of granulation material quality, reduced cost, realized the purpose of the utility model.
The characteristics of the utility model can consult this case graphic and below better embodiment detailed description and obtain to be well understood to.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, further set forth the utility model below in conjunction with specific embodiment.
Like Fig. 3 and shown in Figure 4; Discharging structure is extruded in the modified materials granulation of the utility model; It comprises extrusion die body 100 and is arranged on first discharge opening 110 on the said extrusion die body 100; Also comprise a discharging extension 200, said discharging extension 200 is worked in coordination with said extrusion die body 100, and said discharging extension 200 is arranged on the front end of first discharge opening 110 of said extrusion die body 100; Corresponding position with said first discharge opening 110 is provided with second discharge opening 210 on the said discharging extension 200; The discharging mouth 220 that is provided with hollow and processes in said second discharge opening 210 by antifriction alloy, match with said first discharge opening 110 in the rear end of said discharging mouth 220, and the front end of said discharging mouth 220 matches with said second discharge opening 210.
