Abstract
A kind of method for making precision-investment casting wax-pattern, wax in wax, it is wrapped in the water-soluble core of wax outer layer in wax, it is wrapped in water-soluble core outer layer and the moulding wax three that comprises dead head finally combines formation Wax mold, Wax mold be outer in three-decker, innermost layer is wax in the wax as sub-wax, middle level is the water-soluble core as female wax, outermost layer is then moulding wax, Wax mold is put in water, water-soluble core is met water and is then dissolved, in the wax wrapped up by water-soluble core, wax is flowed out voluntarily by spirality channel, get product after finally unnecessary in cleaning Wax mold water soluble wax wax-pattern.The present invention has the advantages that to reduce production cost in the case of equivalent effect, use manpower and material resources sparingly.
Description
Technical field
The precision-investment casting wax-pattern that the invention belongs to spirality channel water pump makes field, relates to a kind of molten for making
The method of mould hot investment casting wax-pattern.
Background technology
Because the interiors of products of spirality channel water pump exists spirality channel so inconvenient delivery, conventional when producing wax-pattern
Need first to be prefabricated into water-soluble wax the water-soluble core of spirality channel shape, then make in the lump with wax-pattern, the most again by water-soluble core
Dissolve and just define the spirality channel that we are required.But owing to water-soluble wax is expensive, consumed when product is the biggest
Water-soluble wax can cause processing cost the highest, thus ultimately results in product without the market competitiveness.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of method for making precision-investment casting wax-pattern, and it uses
The method of wax in the most prefabricated wax in water-soluble core, in so the most prefabricated when water-soluble core dissolves wax, wax just can utilize
Entering overall circulation, greatly reducing the usage amount of water-soluble wax, it has in the case of equivalent effect to reduce and produces into
Originally, the feature used manpower and material resources sparingly.
In order to achieve the above object, in an embodiment of the present invention, the present invention provides a kind of for making precision-investment casting
The method making wax-pattern, it is characterised in that the method specifically includes following steps:
Making wax in the wax similar to the structure of water-soluble core, in this wax, wax includes the part that can be fixed on Wax mold, institute
In the wax stated, wax is and can be wrapped up one section of sub-wax easily exiting and not rupturing therein, the contour structures of this sub-wax by water-soluble core
Preferably helical structure, sub-wax uses water-insoluble wax material；
One layer of water-soluble wax of peripheral parcel of wax in wax, and the shaping being enclosed with the water-soluble wax of wax in wax is become with
The water-soluble core that cast member internal spiral passage is consistent, water-soluble core can be fully wrapped around firmly as wax in the wax of sub-wax as female wax,
Water-soluble core includes the part that can be fixed on Wax mold, and water-soluble core uses water soluble wax material, this water soluble wax material energy
It is dissolved in water；
Again at one layer of moulding wax of peripheral parcel of water-soluble core, the profile of moulding wax is molded the profile phase one with cast member
Causing and comprise dead head, the material not water soluble wax that this moulding wax is used, in the material that this moulding wax is used and wax
The material that wax is used is identical；
Wax in described wax, it is wrapped in the water-soluble core of wax outer layer in wax, is wrapped in water-soluble core outer layer and comprises moulding of dead head
Shape wax three finally combines formation Wax mold, Wax mold be outer in three-decker, innermost layer is in the wax as sub-wax
Wax, middle level is then for moulding wax as the female water-soluble core of wax, outermost layer；
Being put into by Wax mold in water, water-soluble core is met water and is then dissolved, and in the wax wrapped up by water-soluble core, wax is led to by spiral type
Road flows out voluntarily, and get product after finally unnecessary in cleaning Wax mold water soluble wax wax-pattern.
Owing in wax, wax can repeatedly use, add middle wax of waxing and filled up most water-soluble core inner space, so
Just make water-soluble core actually used to the consumption of water soluble wax material be largely eliminated, thus reduce water soluble wax material
Consumption, it is achieved cost-effective purpose.
The beneficial effects of the present invention is, it has reduction production cost, saving manpower thing in the case of equivalent effect
The feature of power.
Detailed description of the invention
A kind of method for making precision-investment casting wax-pattern, it is characterised in that the method specifically includes following steps:
Making wax in the wax similar to the structure of water-soluble core, in this wax, wax includes the part that can be fixed on Wax mold, institute

Preferably helical structure, sub-wax uses water-insoluble wax material；
One layer of water-soluble wax of peripheral parcel of wax in wax, and shaping Cheng Yuzhu of the water-soluble wax of wax in wax will be enclosed with
The water-soluble core that forging piece internal spiral passage is consistent, water-soluble core can be fully wrapped around firmly as wax, water in the wax of sub-wax as female wax
Molten core includes the part that can be fixed on Wax mold, and water-soluble core uses water soluble wax material, this water soluble wax material energy quilt
Water dissolution；
Again at one layer of moulding wax of peripheral parcel of water-soluble core, the profile of moulding wax is molded the profile phase one with cast member
Causing and comprise dead head, the material not water soluble wax that this moulding wax is used, in the material that this moulding wax is used and wax
The material that wax is used is identical；
Wax in described wax, it is wrapped in the water-soluble core of wax outer layer in wax, is wrapped in water-soluble core outer layer and comprises moulding of dead head
Shape wax three finally combines formation Wax mold, Wax mold be outer in three-decker, innermost layer is in the wax as sub-wax
Wax, middle level is then for moulding wax as the female water-soluble core of wax, outermost layer；
Being put into by Wax mold in water, water-soluble core is met water and is then dissolved, and in the wax wrapped up by water-soluble core, wax is led to by spiral type
Road flows out voluntarily, and get product after finally unnecessary in cleaning Wax mold water soluble wax wax-pattern.
