Abstract
The utility model discloses a port die of a plastic granulator, which comprises a port die body and an extrusion hole. The extrusion hole is arranged in the port die body, and a normal line of a port die plate on the outer side of the extrusion hole and a horizontal line form an acute angle. Since the port die plate on the outer side has a certain angle, the extruded bar materials can be deformed to sag under gravity and a certain angle and a certain spacing between the extruded bar materials and the port die plate are formed. Therefore, the extruded bar materials can not be bonded on the port die plate. Moreover, the bar materials extruded out of the extrusion hole can not be entangled. In addition, the axial line of the extrusion hole and the normal line of the port die plate on the outer side of the extrusion hole are arranged in parallel, so that the discharging path can be shortened, the resistance can be reduced, and the bar materials can not be bonded with the port die plate.
Description
Technical field
The utility model relates to a kind of extruding dies, specifically, relates to a kind of plastic granulator mouth mould.
Background technology
Plastic granulator is made of extrusion main unit, head, a mouthful mould now; plastic raw materials in extrusion main unit, heat and mixing after become the viscous fluid of fusion; the molten plastic of plasticizing compacting is under the screw rod of extruder promotes; enter with certain pressure and speed in the cavity of head; the extrusion cavities that is provided with from the mouth mould is extruded under pressure, and the billot of extruding is made required finished granule through pelletizing again.When the plastic raw materials of melting mixing is extruded mouthful mould, also have quite high temperature, there are not enough strength and stiffness to bear deadweight and distortion.The mouth mould of existing plastic extruding pelletization machine comprises mouthful die body and extrusion cavities; extrusion cavities is arranged in a mouthful die body; the normal that extrusion cavities exports a side mouth template overlaps with horizontal line; therefore; the billot of extruding can be bonded on the body; the billot that different extrusion cavities are extruded also can bond together, and produces thereby influence is normal.
The utility model content
Technical problem to be solved in the utility model is, a kind of plastic granulator mouth mould is provided, and makes the billot of extruding from extrusion cavities can not be bonded on the body, and also can not bond together from the billot that different extrusion cavities are extruded.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of plastic granulator mouth mould, comprise mouthful die body and extrusion cavities, and this extrusion cavities is arranged in a mouthful die body, and is in an acute angle between the normal of the mouth template in the extrusion cavities outside and the horizontal line.
Adopt the technical solution of the utility model, compared with prior art, because the lateral port template has a fixed inclination, even it is sagging that the billot of extruding is out of shape under the gravity effect, also certain angle and spacing are arranged with mouth template, thereby can not be bonded on the mouth template, and the billot extruded of different extrusion cavities can not bond yet and tangles at one.In addition, the normal parallel of the mouth template in the axis of extrusion cavities and this extrusion cavities outside makes the discharging path short, and resistance is little, more difficult billot and the mouth template bonding of making.
As further improvement, the normal parallel of the mouth template outside the axis of described extrusion cavities and this extrusion cavities, feasible like this mouthful of molded making conveniently, the discharging path is short during use, and resistance is little, and more difficult and mouth template bonds.
Description of drawings
Fig. 1 is a kind of structure cutaway view of the present utility model.
Fig. 2 is an another kind of structure cutaway view of the present utility model.
Among the figure, 1. mouthful die body, 2. extrusion cavities, 101. mouth templates.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is specifically described.
As shown in Figure 1, a kind of plastic granulator mouth mould of the present utility model comprises mouthful die body 1 and extrusion cavities 2, and this extrusion cavities 2 is arranged in mouthful die body 1, and is in an acute angle between the normal of the mouth template 101 in described extrusion cavities 2 outsides and the horizontal line.In the technical program, the direction of the mouth template 101 in extrusion cavities 2 outsides is changed, make its normal direction and horizontal line have certain angle, and this angle is an acute angle.This acute angle is good at 30 degree between 60 degree, for example 30 degree, 45 degree or 60 degree.Owing to adopt lateral port template 101 that a fixed inclination is arranged, even it is sagging that the billot of extruding is out of shape under the gravity effect, certain angle and spacing are arranged yet, thereby can not be bonded on the mouth template 101, and the billot extruded of different extrusion cavities 2 can not bond yet and tangles at one with mouth template 101.
Further, as shown in Figure 2, the normal parallel of the mouth template 101 in the axis of described extrusion cavities 2 and this extrusion cavities 2 outsides promptly also has the angle of an acute angle between the axis of extrusion cavities 2 and the horizontal line.The normal parallel of the mouth template 101 in the axis of extrusion cavities 2 and this extrusion cavities 2 outsides, feasible on the one hand mouthful of molded making conveniently, on the other hand in use, because the discharging path is short, resistance is little, so more difficult billot and mouth template 101 bondings of making.
The utility model also can be provided with heater on the mouth die body on the foregoing description basis, further improve plasticizing effect, makes discharging more stable.
Claims (3)
1. a plastic granulator mouth mould comprises a mouthful die body (1) and extrusion cavities (2), and this extrusion cavities (2) is arranged in a mouthful die body (1), it is characterized in that, and is in an acute angle between the normal of the mouth template (101) in described extrusion cavities (2) outside and the horizontal line.
2. according to the described plastic granulator mouth of claim 1 mould, it is characterized in that the normal parallel of the mouth template (101) in the axis of described extrusion cavities (2) and this extrusion cavities (2) outside.
3. according to claim 1 or 2 described plastic granulator mouth moulds, it is characterized in that described acute angle is between 30 degree are spent to 60.
