Abstract
The utility model discloses a kind of casting moulds for the symmetrical duplex switchable filter housing of three pieces, its key points of the technical solution are that including mold, there are two the casting cavities being symmetrical set for setting in the mold, the cavity shape of the casting cavity is identical with the filter housings shape size, the the first mold loam core and the second mold loam core of two casting cavities are provided through in the mold, the first mold loam core is located at the upper flanges opening of two casting cavities, and the second mold loam core is located at the lower end flanges opening of two casting cavities.A kind of casting mould for the symmetrical duplex switchable filter housing of three pieces of the utility model improves casting quality, and improve production efficiency.
Description
Technical field
The utility model is related to a kind of casting moulds for the symmetrical duplex switchable filter housing of three pieces.
Background technology
When producing duplex switchable filter cast iron connection housing, the cast iron connection existing casting technique of housing is single
Casting, in casting process, connection housing cavity easily generates the casting flaw of core shift, and inner cavity loam core is floated by molten iron during cast
Power and float, cause connect housing wall unevenness it is even, drawing requirement is not achieved, casting is scrapped, reduce casting qualified rate, increase
The production cost of product, and low production efficiency.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide one kind to improve casting quality, and
Improve the casting mould for the symmetrical duplex switchable filter housing of three pieces of production efficiency.
To achieve the above object, the utility model provides following technical solution：One kind can cut for the symmetrical duplex of three pieces
The casting mould of filter housings is changed, including mold, there are two the casting cavity being symmetrical set, institutes for setting in the mold
The cavity shape for stating casting cavity is identical with the filter housings shape size, and two castings are provided through in the mold
The the first mold loam core and the second mold loam core of chamber are made, the first mold loam core is located at the upper flanges opening of two casting cavities
Place, the second mold loam core are located at the lower end flanges opening of two casting cavities.
The utility model is further arranged to：The upper end of the mold is provided with the injection hole of two casting cavities of connection.
The utility model is further arranged to：The injection hole is located at the surface of the first mold loam core.
The utility model is further arranged to：Side bottom in the mold positioned at casting cavity is provided with third mold
Loam core, third mold loam core are used to produce the mudhole of the filter housings.
The utility model tool has the advantage that：By the setting of two casting cavities, and pass through the first mold loam core and second
The cooperation of mold loam core improves production efficiency, and the connection housing of this cast can be to avoid the casting flaw of core shift, wall
It is thick uniformly to improve the quality of casting, reduce the production cost of product, it, can be into one by the setting of third mold loam core
When step improves die casting, the situation of cast iron floating.

Specific embodiment
With reference to shown in Fig. 1, a kind of casting mould for the symmetrical duplex switchable filter housing of three pieces of the present embodiment,
Including mold 1, there are two the casting cavity 2 being symmetrical set, the cavity shapes of the casting cavity 2 for setting in the mold 1
It is identical with the filter housings shape size, the first mold mud of two casting cavities 2 is provided through in the mold 1
3 and second mold loam core 4 of core, the first mold loam core 3 are located at the upper flanges opening of two casting cavities 2, and described second
Mold loam core 4 is located at the lower end flanges opening of two casting cavities 2.
The upper end of the mold 1 is provided with the injection hole 5 of two casting cavities 2 of connection.
The injection hole 5 is located at the surface of the first mold loam core 3.
Side bottom in the mold 1 positioned at casting cavity 2 is provided with third mold loam core 6, and third mold loam core 6 is used
In the mudhole of the production filter housings.
By using above-mentioned technical proposal, according to the casting symmetrical float ball elastic packing duplex switchable filter three of three pieces
The design feature of piece symmetrical expression is cast using " load carrying type ", and two connection housings are symmetrically put, primary two connections of casting simultaneously
The casting technique of housing.The beneficial effects of the utility model not only increase production efficiency, and the connection housing of this cast
It can improve the quality of casting to avoid the casting flaw of core shift, uniform wall thickness, reduce the production cost of product.
" load carrying type " is cast, and two connection housings are symmetrically put, and loam core connects at the connecting flange holes by connecting housing
Fixation is connect, connection housing cavity loam core would not be floated in cast by the buoyancy of molten iron, ensure that connection shell casting wall
It is thick uniform, improve casting quality.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, several improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
