Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and the She Sha mechanism that a kind of exhaust noise is little, can effectively solve the core shooter of exhaust band sand problem is simultaneously provided.
In order to achieve the above object, the She Sha mechanism of the designed a kind of core shooter of the present invention, comprise air storage chamber, penetrate chamber, penetrate head, water-cooled is penetrated plate, core box and jacking cylinder, wherein air storage chamber is vertically run through in the above-mentioned chamber of penetrating, penetrate head sealing noose on the bottom port of penetrating chamber, water-cooled is penetrated plate sealing gear and is connected on the exit wound of bullet position of penetrating head, above-mentioned core box be positioned at penetrate head cold water penetrate plate under, jacking cylinder and core box are in transmission connection, it is characterized in that She Sha mechanism in above-mentioned also includes leads sand cartridge module, this leads sand cartridge module mainly by leading sand cylinder, end cap and penetrate sand film composition, wherein penetrating sand film is kept off and being connected in the top port of penetrating chamber by end cap seal, leading sand cylinder vertically runs through successively above-mentioned end cap and penetrates sand film, and its hypomere extends into be penetrated in chamber, on above-mentioned end cap, be also provided with and realize the flashboard of leading the conducting of sand cylinder and closure state switching, on the above-mentioned sidewall of penetrating head, be provided with air bleeding valve.
The She Sha mechanism of above-mentioned provided a kind of core shooter, has cancelled blasting unit assembly in its mechanism, change into and lead sand cylinder, and this is led on sand cylinder and does not crack.While penetrating sand, compressed air, by leading sand cylinder and penetrating the passage between chamber, acts directly on core sand.Enter compressed air and its elicitation effect of core sand of penetrating chamber.Lead the manufacture of sand cylinder simple, the life-span is long, does not need to remove cleaning.Also cancel original rapid escape valve simultaneously, by air bleeding valve being installed penetrating on head, shot away after sand, penetrated compressed air in chamber and see through layer of sand and discharge from air bleeding valve, greatly reduced exhaust noise, also eliminated the problem of exhaust band sand simultaneously.
As further technological improvement, on above-mentioned end cap, be provided with the flashboard seal matching with flashboard bottom surface.Sealing good stability in this further Technological improvement plan between end cap and flashboard, result of use is good.
The She Sha mechanism of a kind of core shooter that the present invention obtains, it shoots away after sand, exhaust noise while getting rid of the compressed air of penetrating in chamber is little, in exhaust without fine sand, can not produce large impact to the air quality of workshop, simultaneously in its structure to lead sand cylinder easy to manufacture, long service life, carries out frequent clean but also do not need to remove.
