Description
Technical field
The present invention relates to sand casting riser technical field more particularly to a kind of reusable spherical feeder molds
And spherical feeder production method.
Background technique
In casting industry, riser is artificially designed in casting mold, and the structural body of molten metal is stored, and is formed to compensate casting
Contraction in the process, plaing a part of, which prevents casting from generating shrinkage cavity and porosity, has both exhaust, collection slag, guides and fill type.
Emitting mouth-shaped can be the various shapes such as cylindrical, top dome is cylindrical, rectangular, spherical.The modulus of riser determines
Its feeding capacity, the selection of riser is in addition to considering its feeding capacity, it is also necessary to pay attention to liftability, in order to reuse, save
Cost.In riser type of different shapes, under the premise of consuming same weight molten metal, spherical feeder has maximum mould
Number, feeding performance are most strong.
But spherical feeder is due to its features of shape, can not molding, workability is poor, generally uses evaporative pattern mold or pre-
Core scheme is buried, but can not be reused, use cost is virtually increased.
Summary of the invention
It is necessary to propose it is a kind of different from the use of evaporative pattern mold or superimposed core scheme production the repeatable of spherical feeder make
Spherical feeder mold.
It is a kind of different from the use of evaporative pattern mold or the spherical feeder production method of superimposed core scheme it is necessary to propose.
A kind of reusable spherical feeder mold, the ball mould of eck mould, formation spherical feeder including formation riser neck,
The draft for pulling out lid is formed, eck mould, ball mould, draft are sequentially connected from bottom to top, and the ball mould is dough deformation body, tool inside ball mould
There is inflatable sealing cavity, the sealing cavity of ball mould is connected to eck mould and draft respectively, and inflating port is opened up on draft.
A method of using the reusable spherical feeder Mold Making spherical feeder, including walk as follows
It is rapid:
It is inflated along the inflating port of draft into ball mould, ball mould is made to form spherical die；
By the bottom of eck mould and the preset riser locating slot of casting die to positive positioning；
Quicksand around to casting die and eck mould, ball mould, draft, starts moulding；
Quicksand in place after, wait molding sand hardening；
After sand mold, which reaches hardening, to be required, inflating port is opened, the compressed air in the ball mould is released, so that ball mould is received
Contracting；
It is discharged to air, when the ball mould is in no gaseity, holding pulls out lid for the reusable spherical feeder
Mold is extracted, and the production of spherical feeder is completed.
Spherical feeder die for manufacturing of the present invention passes through the air bag that setting state can be changed, and realizes the spherical feeder
Die for manufacturing can smoothly take out after completing, and solve the difficulty of spherical feeder production.Spherical feeder is improved simultaneously
The utilization rate of die for manufacturing is no longer disposable mold, reduces production nonrecurring cost.
The production method through the invention, it may be convenient to make spherical feeder, be the use of spherical feeder, provide
Convenient condition, improves the product yield of casting, while reducing product feeding as caused by other shapes riser
The disqualification rate of inadequate defect.
