Description
Technical field
The present invention relates to sand casting rising head technical field, more particularly to a kind of reusable spherical feeder mould
And spherical feeder preparation method.
Background technology
In casting industry, rising head is artificially designed in casting mold, stores the structure of molten metal, is formed to compensate casting
During contraction, play a part of to prevent casting from producing shrinkage cavity and porosity and having exhaust, collection slag concurrently, guide and fill type.
Emit the various shapes such as mouth-shaped can be cylindrical, top dome is cylindrical, square, spherical.The modulus of rising head determines
Its feeding capacity, the selection of rising head is in addition to its feeding capacity is considered, it is also necessary to pays attention to liftability, in order to reuse, saves
Cost.In rising head type of different shapes, on the premise of same weight molten metal is consumed, spherical feeder has the mould of maximum
Number, feeding performance are most strong.
But spherical feeder is due to its features of shape, can not molding, workability is poor, typically using evaporative pattern mold or pre-
Core scheme is buried, but can not be reused, virtually adds use cost.
The content of the invention
It is necessary to propose a kind of to make the repeatable of spherical feeder different from the use of evaporative pattern mold or superimposed core scheme and make
Spherical feeder mould.
It is necessary to propose a kind of different from the use of evaporative pattern mold or the spherical feeder preparation method of superimposed core scheme.
A kind of reusable spherical feeder mould, including the ball mould of the eck mould of formation riser neck, formation spherical feeder,
The withdrawing pattern for pulling out lid is formed, eck mould, ball mould, withdrawing pattern are sequentially connected from bottom to top, and the ball mould is dough deformation body, is had inside ball mould
There is inflatable sealing cavity, the sealing cavity of ball mould is connected with eck mould and withdrawing pattern respectively, and inflation inlet is opened up on withdrawing pattern.
A kind of method of reusable spherical feeder Mold Making spherical feeder described in utilization, including following step
Suddenly：
Inflated along the inflation inlet of withdrawing pattern into ball mould, ball mould is formed spherical die；
The bottom of eck mould and the default rising head locating slot of casting die are aligned into positioning；
Quicksand around to casting die and eck mould, ball mould, withdrawing pattern, starts moulding；
After quicksand terminates in place, molding sand hardening is waited；
After sand mold, which reaches hardening, to be required, inflation inlet is opened, releases the compressed air in the ball mould so that ball mould shrinks；
Treat that air discharges, when the ball mould is in without gaseity, holding pulls out lid by the reusable spherical feeder mould
Extract, complete the making of spherical feeder.
Spherical feeder die for manufacturing of the present invention realizes the spherical feeder by setting the air bag of state variable
Die for manufacturing can smoothly take out after completing, and solve the difficulty of spherical feeder making.Improve spherical feeder simultaneously
The utilization rate of die for manufacturing, no longer it is disposable mould, reduces production nonrecurring cost.
Pass through preparation method of the present invention, in that context it may be convenient to make spherical feeder, be the use of spherical feeder, there is provided
Convenient condition, improves the product yield of casting, while reduce product due to feeding caused by other shapes rising head
The disqualification rate of inadequate defect.
