Abstract
A casting and manufacturing process for metal ware casting ice fire is mainly used for metal ware casting, and comprises the following manufacturing steps: (1) manufacturing an inner die and an outer die: manufacturing an inner die and an outer die according to the shape of a product; (2) liquid injection: after the manufactured inner and outer molds are fixed, liquid is injected into the gap between the inner and outer molds; (3) freezing: placing the liquid-injected mould in a freezing box for freezing; (4) demolding: removing the inner mold and the outer mold to obtain an ice mold; (5) combining an ice mold: combining and trimming ice molds to be combined below the air temperature of 0 ℃; (6) sand placement: filling fine sand inside and outside the trimmed ice mold, and reserving a casting opening; (7) melting: heating to melt the ice mold and form product-shaped gaps in the fine sand; (8) casting: and injecting molten liquid metal into the gaps in the shape of the product, and removing the fine sand after the liquid metal is solidified.
Description
Technical field
The invention belongs to cast class technique, it is used for metalware casting ice fire casting manufacture craft more particularly to one kind.
Background technology
Casting class technique has wax casting, sand casting, three kinds of die pressure casting method at present, and the demoulding of wax casting is to cause mistake
Very, repairing is extremely wasted time and energy, but product condition is perfect；Other both of which have the demoulding of obvious flat shape or perpendicular shape
Line, condition are mediocre.
The content of the invention
In order to solve the above problems, it is used for metalware casting ice fire casting it is an object of the invention to provide one kind and makes
Technology process, this technique is simple, and ice mould is easily stripped and will not distortion, the completely demoulding without any shape in the demoulding
Line.
Realize the technical solution adopted in the present invention：(1) outer mold in making：Interior external mold is produced according to shape of product
Tool；(2) fluid injection：After the interior outer mold made is fixed, liquid is injected in the gap of inside outer mold；(3) freeze：By fluid injection
Mould be placed in household freezer and freeze；(4) it is stripped：Interior outer mold is removed to obtain ice mould；(5) combination of ice mould：Below 0 degree of temperature
The ice die combination for needing to merge is repaired；(6) sand is put：The fine sand mixed with coagulator will be filled up inside and outside ice mould after finishing, stay and pour
Casting nozzle；(7) dissolve：Heating allows ice mould to dissolve, and forms the space of shape of product；(8) cast：Injected in the space of shape of product
The liquid metal dissolved, remove fine sand after liquid metal solidification.
The liquid of the gap injection of inside external mold both can be water, and other liquid and additive that easily condense also can be selected.
Brief description of the drawings
Technical scheme is further illustrated below in conjunction with the accompanying drawings.
Outer mold and gap schematic diagram in Fig. 1；Fig. 2 combination of ice moulds put husky schematic diagram.
Embodiment
With reference to figure 1, external mold (1) is made, internal model is fixed after (2)；Inner noted to the space (3) of external mold (1) internal model (2)
Enter easy solidifying liq；Then it is overall to be freezed；Taken out after icing, external mold (1), internal model (2) are removed when starting to melt, obtained
Part or all of ice mould；With reference to figure 2, the ice mould for needing to merge is merged below 0 degree, then is repaired；After combining
The inside and outside of ice mould (6) fill out fine sand (5) and put sandbox (7) into, fine sand (5) needs plus some coagulators；Treat that ice mould dissolves
The space of shape of product is formed afterwards；After the liquid metal that dissolves of casting gate (4) injection, metal freezing, inside and outside is quickly removed
Sand (5), obtain desired product.
The technological principle of the present invention：Using liquid condensation and dissolve, obtain the space of the shape of wanted product, then note
Enter the liquid metal dissolved, obtain product.
Claims (2)
1. one kind is used for metalware casting ice fire casting manufacture craft, its making step includes：(1) outer mold in making：Root
Interior outer mold is produced according to shape of product；(2) fluid injection：After the interior outer mold made is fixed, in the gap of inside outer mold
Inject liquid；(3) freeze：The mould of fluid injection is placed in household freezer and freezed；(4) it is stripped：Interior outer mold is removed to obtain ice mould；
(5) combination of ice mould：The ice module for needing to merge is merged into finishing below 0 degree of temperature；(6) sand is put：Inside and outside the ice mould after finishing
Fine sand is filled up, stays casting gate；(7) dissolve：Heating allows ice mould to dissolve, and the space of shape of product is formed in fine sand；(8) cast：
The liquid metal dissolved is injected in the space of shape of product, removes fine sand after liquid metal solidification.
2. casting technique according to claim 1, it is characterised in that：Inwardly the liquid of the gap injection of external mold both can be
Water, other liquid and additive for easily condensing also can be selected.
