Molten metal melted in intermediate frequency furnace of connecting is fitted into holding furnace 38, stalk 43 is installed.On bracket 39
Sandbox be moved to designated position, then promote holding furnace 38 using hydraulic cylinder 46, make stalk 43 and sandbox is adjacent to sealing,
Sandbox is blocked using sandbox pressing plate 41, achievees the purpose that fixing seal.It is passed through gas into holding furnace 9, is made in holding furnace 38
Molten metal passes through stalk 43 under the effect of the pressure and injects metal mold cavity, keeps certain pressure, falls after making metal freezing
Sandbox moves right after holding furnace 38, and holding furnace 38 rises, and carries out next working cycles, the metal in holding furnace 38
Liquid is poured.The equipment all by programming intelligent control, can work out various curve controlleds.
Low-pressure casting machine 2 is mainly used for producing iron and steel casting using low-pressure casting process, will melt in series connection intermediate frequency furnace
It is whole to be lifted holding furnace in good molten metal injection holding furnace, by stalk and metal mold plane contact, sealing, to heat preservation
Molten metal pressurizes in furnace, increase metal bath surface, injects metal mold cavity, achievees the purpose that full of casting mold.The technique has metal
Liquid fills that type is steady, and molten metal slag inclusion is few, and consistency is high, is conducive to thin-wall part production.It is the effective way for obtaining high quality casting.
The course of work of the present embodiment:
Molding sand is quantitatively adding in sand mixer 14 by the present apparatus by screw(-type) feeder 15 using intelligent control method according to the time, is blended
30S-60s, then sand mixer 14 is added in the additive of certain volume with additive proportioning device 16 and is mixed, it is then fixed with waterglass
It measures device 17 and sand mixer 14 is added in the waterglass of volume quantitative, be blended 30-180s.Material (water glass type after being mixed uniformly
Sand) enter and penetrates in sand bucket 13, driving two sides clamping cylinder 12 clamps two side molds 10 with mid-part 11, drives compressed oil cylinder
18 will penetrate sand bucket 13 compresses with two side molds 10 and mid-part 11 combined, and the sand jet outlet for penetrating sand bucket 13, which passes through molding sand, to be penetrated
The mode of sand is injected into sandbox 9, is unclamped two sides clamping cylinder 12, is obtained sand mold.
This production line carries out sandbox using the inorganic sodium silicate binder sand that sand host has been blended is penetrated by the above process
Sand molding is penetrated, the sand mold after fastening is transmitted to low-pressure casting position, before in mid-frequency melting furnace in melted molten metal process
It after the refining of frequency refining furnace, goes in low-pressure casting machine, carries out low-pressure casting, the casting after pouring is through supercooling in shakeout position
Knockout is carried out, casting, which is gone in riser cutting machine, cuts riser, and old sand is transmitted to old sand by old sand transmission mechanism and recycles storehouse
It is recycled.And casting reaches ball blast in shot-blasting machine by transmission roller channel, goes to automatic grinding by transmission roller channel later
Reconditioning casting in machine is put in storage after passed examination through inspection operation after fixing, and sandbox passes through production line after separating with casting and turns
Next working cycles are carried out to sand host is penetrated.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
Variation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
