Abstract
The utility model relates to a kind of bell housing low pressure casting die, it is characterized in that: comprise upper die component and lower mold assemblies, described upper die component can be closed up and down with described lower mold assemblies by release link or depart from, and jointly surrounds the mold cavity matched with bell housing between described upper die component and lower mold assemblies; Described upper die component comprises the patrix connecting plate, die pad and the liftout fixed head that set gradually from top to bottom, described lower mold assemblies comprises lower mold body, be positioned at the side of this lower mold body sidewall takes out and counterdie connecting plate, be provided with slide block between described lower mold body and described counterdie connecting plate, described counterdie connecting plate offer the cast gate connected with described mold cavity.Achieve reduction in foundry goods process and build molten metal pressure used, and the quality of bell housing foundry goods can be significantly improved.
Description
Technical field
The utility model belongs to die casting technical field, is specifically related to a kind of bell housing casting mould.
Background technology
Traditional bell housing generally adopts gravitational casting, and gravitational casting refers to that molten metal injects the technique of casting mold under terrestrial gravitation effect, and its technique has following shortcoming:
1, product compactness is low;
2, product surface fineness is not high;
3, fill type slow, production efficiency is low.
Utility model content
Technical problem to be solved in the utility model is the low pressure casting die providing a kind of bell housing for above-mentioned prior art, to obtain high-quality bell housing spray.
The technical scheme in the invention for solving the above technical problem is: a kind of bell housing low pressure casting die, comprise upper die component and lower mold assemblies, described upper die component can be closed up and down with described lower mold assemblies by release link or depart from, and jointly surrounds the mold cavity matched with bell housing between described upper die component and lower mold assemblies; Described upper die component comprises the patrix connecting plate, die pad and the liftout fixed head that set gradually from top to bottom, described lower mold assemblies comprises lower mold body, be positioned at the side of this lower mold body sidewall takes out and counterdie connecting plate, be provided with slide block between described lower mold body and described counterdie connecting plate, described counterdie connecting plate offer the cast gate connected with described mold cavity.
Preferably, described lower mold body comprises the first lower module and second lower module of lower support cooperation.
The technique that above-mentioned bell housing low pressure casting die is corresponding is, first in the crucible of sealing, passes through dry compressed air, and make the molten metal in crucible increase along stalk under the influence of air pressure, the cast gate via counterdie connecting plate enters mold cavity.Then the gas pressure in maintenance crucible above molten metal is until the molten metal in mold cavity solidifies formation foundry goods completely, the gas pressure contacted in crucible above molten metal makes not solidified molten metal in stalk again be back in crucible afterwards, and last open form releases bell housing foundry goods.
Compared with prior art, the utility model has the advantage of: the low pressure casting die providing a kind of bell housing, make molten metal filling mold cavity from lower to upper under pressure, be convenient to realize reducing pressure used in foundry goods process.Advantage comprises: it is steady that liquid metals fills type; Casting forming is good, is conducive to the part forming clear-cut, any surface finish; Cast structure is fine and close, and mechanical performance is high; Improve the technique recovery rate of molten metal, generally do not need rising head, the recovery rate of molten metal is improved greatly, and recovery rate generally can reach 90%.
Accompanying drawing explanation
Fig. 1 is the structural representation of bell housing low pressure casting die in the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of bell housing low pressure casting die in the present embodiment, comprise upper die component and lower mold assemblies, described upper die component can be closed up and down with described lower mold assemblies by release link 4 or depart from, and jointly surrounds the mold cavity matched with bell housing between described upper die component and lower mold assemblies; Described upper die component comprises the patrix connecting plate 1, die pad 2 and the liftout fixed head 3 that set gradually from top to bottom, described lower mold assemblies comprises lower mold body, lower mold body comprises the first lower module 5 and the second lower module 7 that lower support coordinates, 6 and counterdie connecting plate 9 are taken out in the side being positioned at this lower mold body sidewall, between second lower module 7 and described counterdie connecting plate 9 of below, be provided with slide block 8, described counterdie connecting plate 9 offer the cast gate 10 connected with described mold cavity.
The technique that above-mentioned bell housing low pressure casting die is corresponding is, first in the crucible of sealing, passes through dry compressed air, and make the molten metal in crucible increase along stalk under the influence of air pressure, the cast gate via counterdie connecting plate enters mold cavity.Then the gas pressure in maintenance crucible above molten metal is until the molten metal in mold cavity solidifies formation foundry goods completely, the gas pressure contacted in crucible above molten metal makes not solidified molten metal in stalk again be back in crucible afterwards, and last open form releases bell housing foundry goods.
The bell housing low pressure casting die of said structure achieves reduction in foundry goods process and builds molten metal pressure used, and can significantly improve the quality of bell housing foundry goods.
In addition to the implementation, the utility model also includes other embodiments, the technical scheme that all employing equivalents or equivalent substitute mode are formed, within the protection domain that all should fall into the utility model claim.
