Abstract
The invention provides an adapting form precision casting filter sprue cup, and belongs to the technical field of casting and modeling related to investment precision casting. The adapting form precision casting filter sprue cup comprises a big-end-up hollow truncated cone-shaped cup body, wherein the height of the cup body is greater than the height of an inverted conical section at the upper part of a sprue for shell casting; the lower surface of the cup body is connected with an annular bottom plate for holding a filter; the outside diameter of the bottom plate is greater than or equal to the inside diameter of the lower end of the inverted conical section of the sprue; the filter is arranged on the upper surface of the bottom plate; the lower surface of the bottom plate is connected with a hollow lower cup body; and the inner cavity of the lower cup body communicates with the inner cavity of the cup body. The adapting form precision casting filter sprue cup can help satisfy the requirements of customers for internal quality and finished surface quality of precision castings; and the sprue cup can be directly taken away conveniently after molten metal pouring, and does not influence the effect of atmospheric pressure on the sprue at all, thereby being more beneficial to effective feeding to a casting thermal center by means of the sprue.
Description
Technical field
The present invention relates to a kind of casting and molding part relevant with precision-investment casting, a kind of spigot-and-socket essence is in particulard relate to
Casting filter sprue cup.
Background technology
As client is to precision casting internal soundness and the requirement more and more higher of polished surface quality, hot investment casting melting
It is more and more using filter cleaning molten metal during cast.The way of conventionally employed filter cleaning molten metal is：Technique
During design, in one step of sprue inner chamber upper design of casting shell, the top of sprue is back taper pipe, and its lower end is
Pipe, the step is located at the intracavity bottom of back taper pipe, and filter is placed on the step before cast.But this pouring type
After molten metal is poured, filter due to being completely embedded with sprue internal chamber wall, by work remove filter it is highly difficult,
Because the removal time is long so that the molten metal poured into a mould can not be incubated with thermal-insulating covering agent in time, so that being located at filter
The molten metal at place has blocked effect of the atmospheric pressure to sprue easily earlier than the solidification of molten metal in sprue below,
The inner chamber of sprue is formed vacuum state, easily cause the intrinsic molten metal of casting and reversely supplement shrinkage porosite at sprue
Defect, so that sprue should be to the anti-feeding into casting body to sprue of casting body feeding, so as to cause casting
Part ingate root shrinkage defect.
The content of the invention
It is an object of the invention to provide a kind of spigot-and-socket essence casting filter sprue cup, it can aid in and meets client to essence
The requirement of close Internal Quality of Cast and polished surface quality, again can be convenient directly to take away after molten metal is poured, at all
Effect of the atmospheric pressure to sprue is not influenceed, and effective feeding is carried out to casting thermal center so as to be more beneficial for sprue.
In order to realize such scheme, technical solution of the invention is：A kind of spigot-and-socket essence casting filter sprue cup, its
Include up big and down small cavity truncated cone-shaped cup, the back taper on the sprue top of the height more than casting shell of the cup
Duan Gaodu, the lower surface of the cup is connected with the annular base plate for placing filter, the external diameter of the base plate be more than or
Equal to the internal diameter of the back taper section lower end of sprue, the upper surface of the base plate is placed filter, is connected below the base plate
The lower cup body of cavity, the inner chamber of the lower cup body communicates with the inner chamber of cup.
Spigot-and-socket essence casting filter sprue cup of the present invention, wherein the bus of the cup is 5-8 ° with the angle of axis.
Spigot-and-socket essence casting filter sprue cup of the present invention, wherein the lower cup body is cavity round platform small below greatly above
Body, the bus of the lower cup body and the angle of axis are 12-15 °.
Spigot-and-socket essence casting filter sprue cup of the present invention, wherein the cup upper end is provided with outer, the outer is annulus
Shape.
After using such scheme, spigot-and-socket essence casting filter sprue cup of the present invention can be inserted in casting shell by setting
The cup of sprue top back taper section, filter is positioned on the annular base plate of cup lower surface connection, during cast, metal
Liquation enters cup inner chamber from cup upper surface open position, flows directly into lower cup body after being filtered, and from lower cup body
Flow into the sprue of casting shell, after pouring, directly taken away cup rapidly together with filter with steel fork, it is convenient to save
When such that it is able to isothermal holding is carried out to the molten metal for entering casting investment shell intracavity in time, atmospheric pressure pair is not influenceed at all
The effect of sprue, be more beneficial for sprue carries out effective feeding to casting thermal center, helps to meet client to precision casting
The requirement of internal soundness and polished surface quality.
Brief description of the drawings
Fig. 1 is the structural representation of spigot-and-socket essence casting filter sprue cup of the present invention；
Fig. 2 is example structure schematic diagram of the spigot-and-socket essence casting filter sprue cup of the present invention in casting process.
Specific embodiment
As depicted in figs. 1 and 2, spigot-and-socket essence casting filter sprue cup of the present invention, including the small sky of the big lower surface in upper surface
Chamber truncated cone-shaped cup 1, the bus of the cup 1 and the angle of axis are 5-8 °.The height of cup 1 is poured more than the straight of casting shell 6
The back taper section height on the top of road 7, so design is easy to pick and place cup 1.The upper end of cup 1 is machined with annular outer 5, is easy to
After pouring molten metal, cup 1 is taken away with steel fork, it is convenient and time-saving.The lower surface of cup 1 is connected with for placing filter
3 annular base plate 2.Internal diameter of the external diameter of base plate 2 more than or equal to the back taper section lower end of sprue 7.Ensure that cup 1 can pacify
Complete is positioned over above sprue 7.The lower cup body 4 of cavity is connected with below base plate 2, lower cup body 4 is big small below above
Cavity round estrade.The bus of lower cup body 4 and the angle of axis are 12-15 °, and so design is dissipated to mitigate molten metal
