Abstract
The invention provides a precise casting method of a guide vane of a solar generator. The precise casting method comprises the following steps of 1) preparing moulds in inner ring and outer ring shapes by utilizing middle-temperature wax; 2) preparing a module of an annular part between blades by utilizing water-soluble wax; 3) placing the mould prepared by the water-soluble wax between an inner ring and an outer ring to form a transmission mould; 4) pressing the middle-temperature wax into gaps among all the modules in the transition mould, wherein the shapes of the gaps among the modules are the shapes of the blades; 5) dissolving the modules by utilizing weak acid water to obtain a mould which is the same as the shape of the guide vane of the solar generator; and 6) carrying out pulp hanging on the mould obtained by the step 5 and drying pulp to form a layer of a mould shell outside the mould; after melting the mould, obtaining the mould shell; casting metal liquid into the mould shell; and cracking the mould shell after the metal liquid is cooled to obtain a casting piece of the guide vane of the solar generator.
Description
Technical field
The present invention relates to a kind of casting method, especially relate to a kind of casting method of solar generator guide vane.
Background technology
Of Fig. 1 to Fig. 2, the solar generator guide vane comprises inner ring 1, outer ring 3 and is connected the blade 2 of said inner ring 1 and outer ring 3, blade 2 be shaped as " v " font, the quantity of blade 2 is a lot, has 60, and the edge of blade 2 is very thin.For the product of this shape, directly make relatively difficulty of the wax-pattern identical with shape of product, method in the past is to extrude inner ring and outer loop-shaped with wax earlier, the blade slices is combined between inner ring and the outer ring again, forms the wax-pattern identical with shape of product jointly.Because the very thin thickness of blade is easy to stress deformation in anabolic process, cause die deformation, therefore be necessary to change.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of casting method of solar generator guide vane is provided, wax-pattern blade place is not easy distortion.
In order to solve the problems of the technologies described above, the present invention is able to solve through following technical proposals: a kind of casting method of solar generator guide vane comprises the steps: 1) with in warm wax process the mould of inner ring and outer loop-shaped.
2) process shape module partly between the blade with water soluble wax.
3) module of processing said water soluble wax be placed into said between warm the wax inner ring and outer ring processed, be combined into a transition mould; Utilize water miscible wax to process the module of the shape between the blade; Again these modules and inner ring and outer ring are made up; Owing between the blade certain distance is arranged; So the thickness of module is so thin unlike blade, so when the module of utilization and inner ring outer ring were combined into the transition mould, module was not easy to deform.
4) be pressed in the space between each said module in the said transition mould in warm wax, the void shape between the module is exactly the shape of blade.
5) with weak acid water said module is dissolved; Obtain one with the identical shaped mould of said solar generator guide vane, weak acid water in the dissolving module, can centering temperature wax bad student destruction; And adopt this method of dissolving; Blade can not receive the effect of power, so blade can keep shape, and mould also just is not easy distortion.
6) mould that obtains in the step 5 is carried out hanging; Slurry drying becomes one deck formwork at said die shape later; After melting said mould, obtain formwork, and then toward the interior casting metals liquid of said formwork; By the time the molten metal cooling is broken said formwork into pieces later, obtains the foundry goods of said solar generator guide vane.
In the last technical scheme, preferred, the step of hanging described in the step 6 is having at least part under vacuum condition, to carry out.Because blade is " v " font, at first, the inboard of blade is not easy to hang up slurry, therefore need under vacuum condition, carry out hanging.
In the last technical scheme, concrete hanging step is that the said mould in the step 6 is placed in the vacuum chamber, carries out arriving for the first time hanging for the third time, from vacuum chamber, takes out and carries out the 4th time to the 8th time conventional hanging.
In the technique scheme, preferred, carry out under vacuum condition toward the step of the interior casting metals liquid of said formwork.The step of casting metals liquid is carried out under vacuum condition, and metal is not easy oxidized, and when casting, and molten metal can not receive air drag, helps molten metal more and is full of whole die cavity.
The invention has the beneficial effects as follows: utilize water miscible wax to process the module of the shape between the blade, again these modules and inner ring and outer ring are made up, owing between the blade certain distance is arranged; So the thickness of module is so thin unlike blade, so when the module of utilization and inner ring outer ring were combined into the transition mould, module was not easy to deform; In the space between interior each the said module of said transition mould, press as middle temperature wax, the void shape between the module is exactly the shape of blade, with weak acid water said module is dissolved again; Obtain one with the identical shaped mould of said solar generator guide vane, weak acid water in the dissolving module, can centering temperature wax bad student destruction; And adopt this method of dissolving; Blade can not receive the effect of power, so blade can keep shape, and mould also just is not easy distortion.

Fig. 2 is the cutaway view of Fig. 1 along A-A.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail.
Referring to Fig. 1 and Fig. 2, a kind of casting method of solar generator guide vane comprises the steps: 1) with in warm wax process the mould of inner ring and outer loop-shaped; 2) process shape module partly between the blade with water soluble wax; 3) module of processing said water soluble wax be placed into said between warm the wax inner ring and outer ring processed, be combined into a transition mould; 4) be pressed in the space between each said module in the said transition mould in warm wax; 5) with weak acid water said module is dissolved, obtain one with the identical shaped mould of said solar generator guide vane; 6) the said mould in the step 5 is placed in the vacuum chamber; Carry out arriving for the first time hanging for the third time; From vacuum chamber, take out then, carry out the 4th time to the 8th time conventional hanging again, become one deck formwork at said die shape behind the slurry drying; Then said mold heated is melted, the cavity shape of the said formwork that stays is identical with said mould; 7) formwork of processing in the step 6 is placed in the vacuum chamber casts, then said formwork is broken into pieces, obtain the foundry goods of said solar generator guide vane.
