Background technology
V method casting technique is a kind of casting technique of environmental protection, is called as third generation molding, and the V method develops rapidly at home at present, and technology is increasingly mature.The casting of V method is the abbreviation of vacuum sealed molding or vacuum moulding casting technique, its principle is to utilize the moulding of plastic sheeting overlay film and seal sandbox, rely on the air in the vavuum pump extraction type, rely on inside and outside pressure official post dry sand consolidation, form a kind of formative method of required die cavity.The sharpest edges of V method casting are that molding sand does not use binding agent, and knockout is easy, makes the consumption of Modeling Material drop to bottom line, reduce antiquated sand, and the recycling rate of waterused of dry sand has reached more than 95%.
The sandbox that utilizes the V method to cast big-and-middle-sized foundry goods at present and use, generally bleed with around the sandbox wall, and caused internal negative pressure value inequality, promptly the negative pressure near sandbox wall place is lower than sandbox middle part negative pressure, thereby influence the castability of foundry goods, particularly for heavy castings, the sandbox space is big, and this defective is more obvious.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of V method casting special shape mo(u)lding box, pump-line is bled and from around bleed and combine, guarantee that the negative pressure at each position of sandbox is even, thus the castability of assurance foundry goods.
The utility model takes following technical scheme to realize:
A kind of V method casting special shape mo(u)lding box, comprise sandbox outer wall and sandbox inwall, constitute negative pressure chamber between the two-layer sandbox wall, described sandbox inwall is provided with aspirating hole and is installed in the filter screen that aspirating hole place filter sand is used, the sandbox middle part also is provided with pump-line, and the surface of described pump-line is provided with porose; The sandbox outer wall is connected with exhaust tube.
Also comprise the screen cloth pressing plate, described filter screen is pressed on the described sandbox inwall with described screen cloth pressing plate, described screen cloth pressing plate is fixed by bolts on the described sandbox inwall, and described metallic sieve is the stainless steel filter screen, and the mesh of described stainless steel filter screen is less than the dry sand particle; Relative installation of aspirating hole on described sandbox inwall and the screen cloth pressing plate, and both apertures are bigger than dry sand particle.This mode is convenient to fixing and is changed filter screen.
Exhaust tube place, described sandbox outside also is provided with for bleed the outward check valve of usefulness of vavuum pump, vacuumizes and keep vacuum to help negative pressure chamber.
Described pump-line is welded on the described sandbox inwall and is communicated with described negative pressure chamber, to realize inwall and pump-line is bled synchronously and protect pressure even.
Be tied with the stainless steel filter screen of mesh on the described pump-line less than the dry sand particle.
Described sandbox outer wall the right and left respectively is provided with a mould turnover and hangs handle, and the time standby rope that sandbox turns over hangs handle place pull-up sandbox at mould turnover.
The coupling part that described sandbox outer wall and described mould turnover hang handle is provided with dowel hole, dowel hole is to make the accurately hole of the insertion alignment pin of location and design of the adjacent two parts of sandbox, the dowel hole of sandbox is corresponding with the alignment pin of template, the location is accurately simple during moulding, also locate when cope and drag box mould assembling, thereby avoided mould shift with this.
Described sandbox outer wall respectively is provided with two symmetrical sandboxes and hangs handle, and sandbox hangs when handle is used to move sandbox and uses.
Described sandbox outer wall is symmetrically arranged with horizontal molding seat board with bayonet, and the molding seat board plays the effect of having filled up sandbox.
The beneficial effects of the utility model are:
A kind of V method casting of the utility model special shape mo(u)lding box, pump-line bled and from around bleed and combine, can stablize the negative pressure in the sandbox, obvious through the actual production result of use, solve present domestic V method and cast the problem that the negative pressure inequality can appear in the sandbox of big-and-middle-sized foundry goods use, can produce large complicated foundry goods.The utility model is simple and reasonable for structure, is easy to make low cost of manufacture and easy to use.
