Abstract
The invention discloses a casting sand box. A double-layer box body (1) comprises an inner wall (2) and an outer wall (3); the inner wall (2) is provided with a plurality of vent holes (4) and comprises a side wall (5) and a bottom surface (6), and the vent holes (4) formed in the bottom surface (6) and the vent holes (4) formed in the side wall (5) are communicated with through holes (8) formed in the outer wall (3) through air deflectors (7) respectively; a cavity formed by the inner wall (2) in an enclosing mode is a casting cavity (9), an evaporative pattern model (10) is arranged in the casting cavity (9), the top end of the double-layer box body (1) is provided with an annular groove (11) which is connected with a top cover (12), and an air hole (17) penetrates through the back bottom end of the top cover (12) to be located over the evaporative pattern model (10). The foundry sand box is simple in structure, high in rigidity, excellent in casting quality and high in cost rate.
Description
Technical field
The present invention relates to a kind of casting sandbox, belong to moulding manufacturing technology field.
Background technology
Lost foam casting is to make of macromolecular material to become and the design of part of casting to be produced, size duplicate full mold mould, after dip-coating fireproof coating drying, it is embedded in drystone sand through three-dimensional vibrating moulding, casting sandbox pours into molten metal liquid under negative pressure state, making macromolecular material model by thermal evaporation extraction, and then the disposal molding New Casting Technique formed after being replaced cooled and solidified by liquid metals produces the novel casting method of foundry goods.
Existing casting sandbox, when bleeding, the negative pressure everywhere in sandbox working chamber is uniform not, affects being smoothed out of lost foam casting operation, and casting product quality out can not be guaranteed.
It addition, existing casting sandbox is difficult to ensure that rigidity, easily deform along with the expansion of metal casting, thus cause the defects such as metal casting shrinkage porosite, foundry goods time serious, will be made to scrap.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, and in casting cavity, negative pressure casts sandbox uniformly everywhere；Further, the present invention provides a kind of good rigidity, on-deformable casting sandbox；Further, the present invention provides the casting sandbox that a kind of foundry goods dregginess is low.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of casting sandbox, including double-layer box body, described double-layer box body includes inner and outer wall, some passages it are provided with on described inwall, described inwall includes sidewall and bottom surface, described passage on described bottom surface is connected with the through hole on described outer wall by wind deflector respectively with the described passage on described sidewall, the cavity that described inwall surrounds is casting cavity, it is placed with evaporative pattern in described casting cavity, the top of described double-layer box body is provided with annular groove, described annular groove is connected with top cover, after pore passes described top cover, bottom is positioned at above described evaporative pattern, described evaporative pattern top is connected with pouring pipe bottom, described pouring after pipe top passes described top cover is connected with cap mouth.
Described cap mouth is funnel type.
It is additionally provided with sand inlet on described top cover.
It is provided with filter screen at described passage.
The described pipe that pours includes bead type.
Being vacuum chamber between described inner and outer wall, described through hole is connected with vacuum pump.
Described sand inlet and the number pouring pipe are at least two.
Some top boards it are provided with between described inner and outer wall.
Described top board includes trapezoidal, and the described trapezoidal upper end is connected with described inner and outer wall respectively with going to the bottom.
Compared with prior art, the invention has the beneficial effects as follows: the setting that the described passage on described bottom surface is connected with the through hole on described outer wall by wind deflector respectively with the described passage on described sidewall, make vacuum pump in casting cavity everywhere the negative pressure of evacuation uniform, drystone sand is made to fill everywhere uniformly in casting cavity, degree of compaction is identical, ensureing being smoothed out of lost foam casting operation, casting product quality out is excellent；The setting of top board, makes casting cavity be unlikely to deform, and good rigidity is further ensured that the quality of metal casting；The setting pouring pipe of bead type, makes the easy emersion of the bits in molten metal, it is ensured that foundry goods dregginess is low, and casting quality is good.A kind of casting sandbox that the present invention provides, simple in construction, rigidity is strong, and casting quality is excellent, and cost rate is high.
