Abstract
The utility model discloses a special gas needle for an external gas auxiliary injection molding. The special gas needle is characterized by comprising a ring arranged at a gas outlet, an air needle core, an air needle sleeve barrel and a connecting device. The air needle core is arranged in the air needle sleeve barrel. One end of the connecting device is connected with the air needle sleeve barrel to press the air needle core and the air needle sleeve barrel tightly. The ring and the air needle core are in interference connection. The middle of the needle core is provided with a hole. One side of the air needle core, close to the position of the gas outlet, is provided with a ring-shaped protrusion. The special gas needle enables the direction of gas injection to be parallel to the application surface, and obtains best molding effect.
Description
Technical field
The utility model relates to a kind of special-purpose air tube for the extraneous gas assisted injection molding.
Background technology
In injection moulding, air-auxiliary injection forming (hereinafter to be referred as " gas is auxiliary ") is used more and more extensive, and wherein extraneous gas assisted injection molding (hereinafter to be referred as " outer auxiliary ") is a kind of emerging technology.Outside in the auxiliary process, because gas is in the plastic surface action, so in the gas inject process, the control of the flow direction during gas inject is vital for the impact of the Forming Quality of plastic.
Now outer auxiliary in used air tube great majority adopt the air tubes of traditional gas assisted molding, this air tube to be conducive to gas to the penetrating of plastic, but be applied to outer auxiliary after because gas pressure is concentrated and direction destroy plastic component structure vertical with action face.
Summary of the invention
In order to overcome in the existing outer assist mold gas flow direction perpendicular to the problem of action face, the utility model provide a kind of can be to greatest extent so that the flow direction during gas inject is parallel to the special-purpose air tube for the extraneous gas assisted injection molding of action face.
The technical solution adopted in the utility model is:
A kind of special-purpose air tube for the extraneous gas assisted injection molding is characterized in that: comprise gas outlet effect ring, air tube core, air tube sleeve and connector, described air tube core is located in the described air tube sleeve, utilizes contour localization in the described air tube sleeve; Described connector one end links to each other with described air tube sleeve and compresses described air tube core and described air tube sleeve, and described ring is connected with the interference of described air tube core; The middle perforate of described air tube core and the side in close gas outlet position are provided with circular protrusion.
Further, described connector and described air tube sleeve connecting place are the screw-in structure;
Further, the other end of described connector and template screw thread are fixed.
Further, the end face size that is connected with template of described connector is greater than the end face that is connected with described air tube sleeve.
Further, the middle both sides of described connector are provided with projection.
Further, the raised structures of both sides is made as hexagon in the middle of the described connector.
The utility model is outside in the auxiliary process, enter the gas effect stage after, gas at first enters air tube by the large side of described connector ends; Enter the air tube sleeve inner by the hole in the middle of the air tube core after entering described air tube core, via the circular protrusion flow-disturbing of air tube core near gas outlet, penetrate from outlet, and because the effect of ring, gas moves along action face, has reduced the pressure that penetrates to plastic surface, exit.
For ease of the air tube assembling, described ring adopts interference fit to be connected with the air tube core, first the air tube core is put into the air tube sleeve when assembling, after compressing with connector ring is knocked in.
When the utility model uses, first air tube is screwed in template, the raised structures in the middle of the connector is hexagon, and is convenient fastening; After template adds sealing ring, with core air tube is compressed, core is reserved counterbore at the position that contacts with air tube, for preventing Leakage Gas, also need add sealing ring.
The beneficial effects of the utility model are embodied in: to greatest extent so that be parallel to action face during gas inject in flow process, obtain best molding effect.
Description of drawings
Fig. 1 is the utility model air tube integral installation figure.
Fig. 2 is the installation diagram of the utility model air tube in mould.
The specific embodiment
With reference to Fig. 1, a kind of special-purpose air tube for the extraneous gas assisted injection molding, characteristics are to comprise gas outlet effect ring 1, air tube core 2, air tube sleeve 3 and connector 4, and described air tube core 2 is located in the described air tube sleeve 3, utilize described air tube sleeve 3 interior contour localizations; Described connector 4 one ends link to each other with described air tube sleeve 3 and compress described air tube core 2 and described air tube sleeve 3, and described ring 1 is connected with described air tube core 2 interference; The middle perforate 5 of described air tube core 2 and the side in close gas outlet position are provided with circular protrusion 6.
Further, described connector 4 is the screw-in structure with described air tube sleeve 3 connecting places;
Further, the other end of described connector 4 and template 8 screw threads are fixed.
Further, the end face size that is connected with template 8 of described connector 4 is greater than the end face that is connected with described air tube sleeve 3.
Further, the middle both sides of described connector 4 are provided with projection 7.
Further, projection 7 structures of both sides are made as hexagon in the middle of the described connector 4.
The utility model is outside in the auxiliary process, enter the gas effect stage after, gas at first enters air tube by the large side of described connector 4 end faces; Enter air tube sleeve 3 inside by the hole 5 in the middle of the air tube core 2 after entering described air tube core 2, via circular protrusion 6 flow-disturbings of air tube core 2 near gas outlet, penetrate from outlet, and because the effect of ring 1, gas moves along action face, has reduced the pressure that penetrates to plastic surface, exit.
For ease of the air tube assembling, described ring 1 adopts interference fit to be connected with air tube core 2, first air tube core 2 is put into air tube sleeve 3 when assembling, after compressing with connector 4 ring 1 is knocked in.
When the utility model uses, first air tube is screwed in template 8, projection 7 structures in the middle of the connector 4 are hexagon, and are convenient fastening; After template 8 adds sealing ring, with core 9 air tube is compressed, core 9 is reserved counterbore at the position that contacts with air tube, for preventing Leakage Gas, also need add sealing ring.
The described content of this specification embodiment only is enumerating the way of realization of inventive concept; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reaches in those skilled in the art conceives the equivalent technologies means that can expect according to the present invention.
