Abstract
The present invention relates to iron casting processing technique field, more particularly to a kind of iron casting processing method, comprise the following steps：A, the mould of iron casting, the rising head body of foam and casting pipeline are placed in the chamber that cope and drag box enclose, and bury into chamber sand and compress reality；B, cope and drag box are opened, mould is taken out, cope and drag box is covered, cavity is formed at mould script position；C, molten metal is injected into cavity through pipeline of casting；D, after treating molten metal coagulation forming, cope and drag box are opened, it is iron casting to take out molding part.In the present invention, rising head body is foam, in process, rising head body is directly placed on mould, when casting metals liquid, rising head body, which can be heated to vaporize, to disappear, so when molding part is taken out in the demoulding, for rising head body because disappearing without being had an impact to the demoulding, technique is simple, and the cost of foam is relatively low, so as to reduce whole processing cost.
Description
Technical field
The present invention relates to iron casting processing technique field, more particularly to a kind of iron casting processing method.
Background technology
Iron casting in machine-building with good combination property because obtaining more and more extensive application, but magnesium iron is cast
The mushy freezing mode that part is presented in casting process causes to shrink tendency greatly, and feeding is difficult, has to use in production process
Rising head carries out feeding, and rising head is to feed metal when casting is formed in die cavity to store the cavity of molten metal, have exhaust,
Collection slag and the effect for preventing shrinkage cavity and porosity.Traditional iron casting processing technology is typically using blank riser, top feeder head with
With insulated feeder etc., and according to principle is solidified from bottom to top, rising head is usually placed in above casting, and this is allowed for after filling moulding
The demoulding is difficult, or meets casting requirement using means such as core, suspended cores, but this undoubtedly adds technology difficulty and worker
The amount of labour, production cost is caused to increase.For a long time, this problem seriously annoyings many casting producers.
The content of the invention
The purpose of the present invention is to overcome the defects of existing demoulding of prior art is difficult, technology difficulty is big, there is provided Yi Zhongrong
The simple iron casting processing method of easy mold release, technique.
The technical solution adopted for the present invention to solve the technical problems is：A kind of iron casting processing method, including it is following
Step：
A, the mould of iron casting, the rising head body of foam and casting pipeline are placed on cope and drag box
In the chamber enclosed, and bury sand into chamber and compress reality, rising head body is placed on mould, the ingate for pipeline of casting and
Mould connects, and the sprue for pipeline of casting connects with sprue cup；
B, cope and drag box are opened, mould is taken out, cope and drag box is covered, at mould script position
Form cavity；
C, molten metal being injected into cavity through pipeline of casting, the heat of molten metal itself causes the vaporization of rising head body to disappear,
Molten metal enters after the vaporization of rising head body in the chamber formed for being fed during casting shaping；
D, after treating molten metal coagulation forming, cope and drag box are opened, it is iron casting to take out molding part.
Preferably, before burying sand in the step a, the positioning iron staff of vertical is inserted with rising head body, positions iron staff
Upper end extend to the top of rising head body.
Further, the positioning iron staff is hollow tubular.
Beneficial effect：In the present invention, rising head body is foam, and in process, rising head body is directly placed at mould
On tool, when taking out mould, rising head body is removed together in company with molding sand；When casting metals liquid, rising head body can be heated vaporization
Disappear, after rising head body disappears, the metal rising head formed will not also have an impact to the demoulding, can be carried out to iron casting
On the basis of feeding, simplify casting technique, improve production efficiency, reduce cost.
Brief description of the drawings
Fig. 1 is that inventive die is put into structural representation when in chamber；
In figure：10- moulds；20- rising head bodies；30- copes；40- drag boxs；50- positions special rod.
Embodiment
With reference to Fig. 1, the invention will be further described.
A kind of iron casting processing method, comprises the following steps：
A, the mould 10 of iron casting, the rising head body 20 of foam and casting pipeline are placed on the and of cope 30
In the chamber that drag box 40 encloses, and bury sand into chamber and compress reality, rising head body 20 is placed on mould 10, cast tubes
The ingate in road connects with mould 10, and the sprue for pipeline of casting connects with sprue cup；
B, cope 30 and drag box 40 are opened, mould 10 is taken out, cope 30 and drag box 40 is covered, mould 10 is former
Cavity is formed at this position；
C, molten metal is injected into cavity through pipeline of casting, the heat of molten metal itself causes the vaporization of rising head body 20 to disappear
Lose, molten metal enters after rising head body 20 vaporizes in the chamber formed for being fed during casting shaping；
D, after treating molten metal coagulation forming, cope 30 and drag box 40 are opened, it is iron casting to take out molding part.
In the present invention, rising head body 20 is foam, and in process, rising head body 20 is directly placed at mould 10
On, when taking out mould 10, rising head body 20 is removed together in company with molding sand；When casting metals liquid, rising head body 20 can be heated
Vaporization disappears, and after rising head body 20 disappears, the metal rising head formed will not also have an impact to the demoulding, can be cast to magnesium iron
On the basis of part carries out feeding, simplify casting technique, improve production efficiency, reduce cost.Wherein, rising head body 20 is steeped by specialty
Foam factory manufactures and has unified standard Riser Dimensions, is so easy to the use of foundry enterprise.Because using the rising head sheet of standard
Body 20 can be easy to produce, purchase, changes, design application etc..
Preferably, before burying sand in the step a, the positioning iron staff 50 of vertical is inserted with rising head body 20, is positioned
The upper end of iron staff 50 extends to the top of rising head body 20.The volume of rising head body 20 is relatively small, is entered using iron staff 50 is positioned
Row positioning, variation is freeed in the position of rising head body 20 when preventing from burying sand.
Further, the positioning iron staff 50 is hollow tubular, is positioned such that iron staff 50 does not just only have positioning function, moreover it is possible to
The gas in chamber is discharged in casting, ensures Quality of Nodular Iron Casting.
It should be appreciated that specific embodiment described above is only used for explaining the present invention, it is not intended to limit the present invention.By
Among the obvious changes or variations that the spirit of the present invention is extended out is still in protection scope of the present invention.
