Abstract
A kind of ice fire casting manufacture craft, is mainly used in metalware casting, and its making step includes：(1) outer mold in making：Interior outer mold is produced according to shape of product；(2) fluid injection：After the interior outer mold that will be made is fixed, liquid is injected in the gap of inside outer mold；(3) freeze：The mould of fluid injection is placed in household freezer and is freezed；(4) demoulding：Interior outer mold is removed and obtains ice mould；(5) combination of ice mould：The ice die combination finishing for merging will be needed below 0 degree of temperature；(6) sand is put：Fine sand will be filled up inside and outside ice mould after finishing, stay casting gate；(7) dissolve：Heating allows ice mould to dissolve, and the space of shape of product is formed in fine sand；(8) cast：To the liquid metal that dissolves is injected in the space of shape of product, fine sand is removed after liquid metal solidification.
Description
Technical field
The invention belongs to cast class technique, more particularly to a kind of ice fire casting.
Background technology
Casting class technique has wax casting, sand casting, three kinds of die pressure casting method at present, and the wax casting demoulding is to cause distortion, repairs very time-consuming expense
Power, but product condition is perfect；Other both of which have the demoulding line of obvious flat shape or perpendicular shape, and condition is mediocre.
The content of the invention
In order to solve the above problems, it is an object of the invention to provide a kind of ice fire casting technique, this process is simple, the easy demoulding of ice mould and not
Can the distortion in the demoulding, the completely demoulding line without any shape.
Realize the technical solution adopted in the present invention：(1) outer mold in making：Interior outer mold is produced according to shape of product；(2) fluid injection：
After the interior outer mold that will be made is fixed, liquid is injected in the gap of inside outer mold；(3) freeze：The mould of fluid injection is placed in cold in household freezer
Freeze；(4) demoulding：Interior outer mold is removed and obtains ice mould；(5) combination of ice mould：The ice die combination finishing for merging will be needed below 0 degree of temperature；
(6) sand is put：The fine sand mixed with coagulator will be filled up inside and outside ice mould after finishing, stay casting gate；(7) dissolve：Heating allows ice mould to dissolve, and is formed
The space of shape of product；(8) cast：To the liquid metal that dissolves is injected in the space of shape of product, fine sand is removed after liquid metal solidification.
The liquid of the gap injection of inside external mold both can be water, also can select other liquid and additive that easily condense.
Specific embodiment
Fixed after making external mold, internal model；Easy solidifying liq is injected in space to external mold internal model；Then it is overall to be freezed；Freeze
After take out, start melt when by external mold, internal model remove, obtain part or all of ice mould；The ice mould for needing to merge is merged below 0 degree,
Repaired again；The inside and outside of the ice mould after combination fill out fine sand and puts sandbox into, fine sand needs plus some coagulators；After ice mould dissolves
Form the space of shape of product；From the liquid metal that casting gate injection is dissolved, after metal freezing, the quick sand for removing inside and outside obtains wanting
Product.
Technological principle of the invention：Using liquid condensation and dissolve, obtain the space of the shape of wanted product, the liquid gold for being then injected into dissolving
Category, obtains product.
