Abstract
The utility model discloses a plastic extrusion mould, including the inner tube, be somebody's turn to do interior intraduct and be equipped with the mandrel, above -mentioned inner tube outside cover is equipped with the outer tube, and vacuole formation between this outer tube and the above -mentioned inner tube, above -mentioned inner tube pipe wall are equipped with the joint -cutting, and above -mentioned interior intraduct passes through above -mentioned joint -cutting and above -mentioned cavity UNICOM, and above -mentioned cavity is equipped with the export, and this exit linkage has the air extractor, and this air extractor can make above -mentioned cavity become the negative pressure cavity. The beneficial effects of the utility model are that: plastic material shaping that this plastic extrusion mould extruded is even, do not have thin and thick difference.
Description
Technical field
The utility model relates to plastic extruder technical field, is specifically related to a kind of plastics extrusion die.
Background technology
In plastic extruding forming equipment, plastic extruder is referred to as main frame usually, and the follow-up equipment plastic extruding forming machine supporting with it is then called subsidiary engine.Plastic extruder, through the development of more than 100 years, derives twin-screw, multiscrew, even without different types of machines such as screw rods by original singe screw.Plastic extruder (main frame) can with tubing, film, handful material, monofilament, flat filament, strap, squeeze the various plastic shaping subsidiary engines such as net, plate (sheet) material, profile shapes, granulation, cable be coated and mate, form various plastic extruding forming production line, produce various plastic products.Therefore, no matter now or in the future plastic extruding forming machinery, be all one of machine of being used widely in plastic processing industry.
Plastic extruder can adopt plastics extrusion die in plastic extrusion process, existing plastics extrusion die generally comprises core, external mold is arranged with outside core, plastic material is shaping between, but the plastic material that this mould of plastics obtains exists shaping uneven, the shortcoming that there is thin and thick difference.
Utility model content
The purpose of this utility model is to provide a kind of plastics extrusion die, the plastic material uniform in shaping that this plastics extrusion die is extruded.
For achieving the above object, the utility model provides following technical scheme:
A kind of plastics extrusion die, comprise interior pipe, this internal tube is provided with core, be arranged with outer tube outside above-mentioned interior pipe, form cavity between this outer tube and above-mentioned interior pipe, above-mentioned inner pipe wall is provided with joint-cutting, above-mentioned internal tube is by above-mentioned joint-cutting and above-mentioned cavity UNICOM, above-mentioned cavity is provided with outlet, and this outlet is connected with air exhauster, and this air exhauster can make above-mentioned cavity become negative pressure cavity.
Preferably, above-mentioned joint-cutting is uniform in inner tube length direction.
Preferably, above-mentioned joint-cutting is interspersed in the upper tube half of interior pipe and lower tube half.
Preferably, above-mentioned joint-cutting curl.
Preferably, the width of above-mentioned joint-cutting is 0.2-0.8 millimeter.
Preferably, the width of above-mentioned joint-cutting is 0.5 millimeter.
Operation principle of the present utility model is: when the plastics of molten condition enter between core and interior pipe, open air exhauster, cavity between outer tube and interior pipe forms negative pressure, due to the joint-cutting on interior pipe, the plastics of negative pressure to molten condition have suction-operated, the section bar of section bar all directions is all subject to this negative pressure and outwards acts on, therefore, comparatively even after plastic material is shaping.Meanwhile, because joint-cutting is comparatively thin, the plastic adherence of melting can not be entered in joint-cutting.
The beneficial effects of the utility model are: this plastics extrusion die extrude plastic material uniform in shaping, there is no thin and thick difference.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
The technical scheme that the utility model is specifically implemented is:
A kind of plastics extrusion die, comprise interior pipe 2, this interior pipe 2 inside is provided with core, be arranged with outer tube 1 outside above-mentioned interior pipe 2, form cavity 3 between this outer tube 1 and above-mentioned interior pipe 2, above-mentioned interior pipe 2 tube wall is provided with joint-cutting 21, above-mentioned interior pipe 2 inside is by above-mentioned joint-cutting 21 and above-mentioned cavity 3 UNICOM, above-mentioned cavity 3 is provided with outlet 31, and this outlet 31 is connected with air exhauster 4, and this air exhauster 4 can make above-mentioned cavity 3 become negative pressure cavity 3.
Above-mentioned joint-cutting 21 is uniform at interior pipe 2 length direction.
Above-mentioned joint-cutting 21 is interspersed in the upper tube half of interior pipe 2 and lower tube half.
The width of above-mentioned joint-cutting 21 is 0.2-0.8 millimeter.
More specifically, the width of above-mentioned joint-cutting 21 is 0.5 millimeter.
Operation principle of the present utility model is: when the plastics of molten condition enter between core and interior pipe 2, open air exhauster 4, cavity 3 between outer tube 1 and interior pipe 2 forms negative pressure, due to the joint-cutting 21 on interior pipe 2, the plastics of negative pressure to molten condition have suction-operated, the section bar of section bar all directions is all subject to this negative pressure and outwards acts on, therefore, comparatively even after plastic material is shaping.Meanwhile, because joint-cutting 21 is comparatively thin, the plastic adherence of melting can not be entered in joint-cutting 21.
The beneficial effects of the utility model are: this plastics extrusion die extrude plastic material uniform in shaping, there is no thin and thick difference.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (6)
