Description
Technical field
The utility model belongs to metal or nonmetal melting and casting or injection moulding technical field, relates to casting or structure of cast die, and more particularly, the utility model relates to the casting technique structure of casting mould.
Background technology
In the prior art, when using vertical-parting not have case casting mould Foundry Production product on the enlightening sand line, two die joints of every case sand mold directly with adjacent sand mold mould assembling, be Hold, the beat of production is than higher (the fastest reach 300 casees/hour), precision height (caning be controlled in the 0.1mm); The liquid metals amount that every case injects is limited, is no more than 30 kilograms general at most; The problem of its existence is:
The volume of every secondary sand mold is less relatively, and usually heat radiation, exhaust can only realize by top in its condensation process, have strengthened the difficulty of the technological design of mould virtually;
The vertical-parting that uses on the enlightening sand line does not have the case casting mould and takes a mould that product model a plurality of or in batches is set mostly---i.e. the product of a plurality of or batch of a mould output, so on the mold model be provided with relatively all narrower, the sand mold space is fully utilized in other words, but the heat radiation, exhaust more the difficulty.
The technical scheme of " utilizing the limited gas permeability of molding sand; the two sides at mould are provided with steam vent; quicken exhaust " is provided in existing patent documentation, and this technical scheme has play a part important really at the casting of middle small dimension product, has improved the percentage of A-class goods of cast article.But at specification product lot quantity Foundry Production bigger than normal, with direct casting ball or casting section, actual product inside still has casting flaws such as blackhead, shrinkage porosite as Φ 30.Because of the molten metal scale of construction is big relatively, the hot gas emission is also big in its condensation contraction process, only can't satisfy the demand by sand mold top, two sides, because of exhaust abundant inadequately, sand mold centre especially, the inherent quality problem can appear in natural cast article.
The utility model content
The problem that the utility model solves provides the casting technique structure of casting mould, its objective is the heat radiation, the exhaust that improve mould, to improve production capacity and product quality.
To achieve these goals, the technical scheme taked of the utility model is:
The casting technique structure of casting mould that the utility model provides, described casting mould comprises mold, be provided with product model, air flue on described mold, described air flue is by the external communications of exhaust outlet and described mold, and described mold is provided with air bag; Described air bag is a cavity structure.
First optimized technical scheme:
Described air bag is communicated with the ventilation by-path, and described ventilation by-path is communicated with air flue.Distance 〉=0.5mm between described air bag and the described product model.
Second optimized technical scheme:
Described air bag directly is communicated with air flue and becomes one.Described air flue also is communicated with the ventilation by-path; Distance 〉=0.5mm between described ventilation by-path and the described product model.
Concrete more specifically scheme:
The cavity shape of described air bag is a truncated conical shape, perhaps is the spherical crown shape, perhaps is semi-spherical shape.
The quantity of described air bag is more than one.
Described ventilation by-path is that the cross section is semicircle or trapezoidal rectangular.
The quantity of described air flue is more than one.
Described exhaust outlet is arranged on the lower end of described mold die cavity.
Described exhaust outlet profile is lamellar, its thickness 〉=0.2mm.
The utility model adopts technique scheme, enlarges ventilative, the exhaust effect of sand mold comprehensively, has enlarged the ventilative area of sand mold, improves the condensation environment, has improved heat radiation, exhaust conditions; Air bag, ventilation by-path, air flue are realized exhaust by outside directly connection of exhaust outlet and sand mold, can suitably hold certain hot gas again, form a brand-new exhaust air technique structure, they or separately or form one and exist, can be arranged on the appropriate location of the non-formed product of sand mold arbitrarily, especially be suitable for the centre of vertical-parting casting sand type, solve the exhaust of sand mold centre, heat radiation well, further improve the quality of cast article, enlarged the scope that enlightening sand line is produced product.When big specification product lot quantity Foundry Production, when the capacity of also promptly dispelling the heat increases, still can guarantee the exhaust that sand mold is more comprehensive, perfect, making Φ 30 no longer is " forbidden zone " to produce on direct casting ball or the casting Duan Zaidi sand line, has improved production capacity and product quality.
