Description
Technical field
The utility model belongs to Casting Technology field, and in particular to a kind of cast structure of Ludox investment-casting.
Background technology
Model casting typically refers to that apperance is made in fusible material, if type is made in apperance Surface coating dried layer refractory material
Shell, then be pourable casting side after high-temperature roasting so as to obtain the casting mold of no die joint by apperance fusing discharge shell
Case.Manufactured, therefore be often referred to as model casting " lost-wax casting " due to the widely used wax material of apperance.The shape of investment-casting
General all more complicated, the castable minimum diameter portalled is up to 0.5mm on casting, and the minimum wall thickness (MINI W.) of casting is 0.3mm.In production
In can by some original parts by several part combinations, by changing the structure of part, be designed to one-piece parts and
Directly cast out by model casting, to save the consumption of machining period and metal material, make design of part more reasonable.Model casting
Technical process is more complicated, and whard to control, and the material for using and consuming is more expensive, therefore it is applied to the complex-shaped, precision of production and wanted
Ask miniature parts that are high or being difficult the other processing of progress, the blade of such as turbogenerator.It is larger especially for Wall-Thickness Difference
Part process is increasingly complex, and thin-walled position needs higher temperature just to fill type completely, and heavy wall position needs lower temperature and fast
Quickly cooling, which but just can guarantee that, occurs without casting flaw inside heavy wall, it is not to owe to cast to be that the contradiction, which often leads to cast out the blank come,
Internal defect, shrinkage cavity.It is calcined because silicasol case will pass through more than under 1000 Celsius temperatures, causes that Quench can not be bonded on wax part
Block.
In view of this, the present inventor devises a kind of cast structure of Ludox investment-casting.
The content of the invention
Technical problem to be solved in the utility model is molten there is provided a kind of Ludox for above-mentioned the deficiencies in the prior art
The cast structure of die casting, promotes the thick big position of casting quickly to cool down, and coordinate the feeding of rising head to act on, it is to avoid the thick big portion of casting
There is casting flaw in position.
The utility model, which solves its technical problem, to be realized using following technical scheme.According to the utility model proposes
A kind of cast structure of Ludox investment-casting, including formwork 1, Quench wax stone 2, wax-pattern 3 and Quench block, the Quench wax stone 2 glue
Tie in the lateral surface of wax-pattern 3；The Quench wax stone 2, wax-pattern 3 are wrapped up by formwork 1 and the outer face of Quench wax stone 2 is exposed, wax-pattern 3
Top is provided with rising head 4；The Quench block is consistent with the shape of Quench wax stone 2, and its cross section is T-shaped, is placed in the Quench wax
In the cavity formed after block 2 is fired.
The utility model is solved its technical problem and also further realized using following technical measures.
The cast structure of foregoing Ludox investment-casting, the Quench block is one in aluminium block, copper billet, graphite block, iron block
Kind.
The cast structure of foregoing Ludox investment-casting, the Quench wax stone 2 is bonded in the outside at the thick big position of wax-pattern 3
Face, wax-pattern 3 is provided with rising head 4 at the top of thick big position.
The utility model proposes the cast structure of Ludox investment-casting mainly solve Ludox precision-investment casting part
Easily there is shrinkage porosite, shrinkage cavity defect problem in thick big position, and Quench block coordinates rising head to eliminate casting flaw, improves Internal Quality of Cast,
So as to improve casting yield.
Described above is only the general introduction of technical solutions of the utility model, in order to be able to better understand technology of the present utility model
Means, and being practiced according to the content of specification, and to allow above and other purpose of the present utility model, feature and excellent
Point can become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, describe in detail as follows.
Brief description of the drawings
Fig. 1 is the schematic diagram of the cast structure of the utility model Ludox investment-casting.
1：Formwork
2：Quench wax stone
3：Wax-pattern
4：Rising head
Embodiment
Further to illustrate that the utility model is to reach technological means and effect that predetermined goal of the invention is taken, below
With reference to accompanying drawing and preferred embodiment, to according to the utility model proposes the cast structure of Ludox investment-casting its specific implementation
Mode, structure, feature and its effect, are described in detail as after.
Referring to Fig. 1, the utility model proposes Ludox investment-casting cast structure, including formwork 1, Quench wax stone
2nd, wax-pattern 3 and Quench block, the Quench wax stone 2 are bonded in the lateral surface of wax-pattern 3；The Quench wax stone 2, wax-pattern 3 are wrapped up by formwork 1
And the outer face of Quench wax stone 2 is exposed, the top of wax-pattern 3 is provided with rising head 4；The Quench block is positioned over the Quench wax stone 2 through roasting
In the cavity formed after burning, the Quench block is consistent with the shape of Quench wax stone 2, and its cross section is T-shaped.
Further, the formwork 1 is prepared from by Ludox bonding agent, the special sand of casting, casting tailored flour.
Further, the Quench block is not limited to for one kind in aluminium block, copper billet, graphite block, iron block, but the utility model
This.
Further, the Quench wax stone 2 is bonded in the lateral surface at the thick big position of wax-pattern 3, and wax-pattern 3 is set at the top of thick big position
Rising head 4. is equipped with specifically, the thick big position of wax-pattern 3 refers to that the wall ratio of the position and intermediate location is more than 10.
Further, when placing Quench block in the cavity formed after the Quench wax stone 2 is fired, the reserved 0.2- in one side
0.5mm gap, and it is spacing by step.
The utility model proposes Ludox investment-casting use flow it is as follows：
When wax part welds pouring technology one piece and Quench block-shaped one are bonded in the lateral surface including the thick big position of wax-pattern
The Quench wax stone 2 of sample, the formwork 1 during the process for making shell on the outer face of Quench wax stone 2 will be wiped off, it is ensured that outer face is exposed
In air, formed the utility model proposes cast structure.After the shell made is by the roasting that dewaxes, Quench wax stone 2 dissolves
The Quench block of preheated same shape is positioned over the cavity before forming a cavity connected with the external world, cast aluminium alloy
Interior, because the cross section of Quench wax stone 2 is T-shaped, the depth that is put into of Quench block can be spacing by step.And to prevent Quench block from moving back
Go out, casting joint sealing mud cream can be spread in cylindrical applied with formwork intersection of Quench block step.
The aluminium alloy at the thick big position of casting is directly contacted with Quench block after cast, and quickly absorbing heat by Quench block makes thickness
Big position rapid solidification, so that solving the thick big position of casting shrinkage cavity, rarefaction defect easily occurs.
It is described above, only it is preferred embodiment of the present utility model, any those skilled in the art, not
Depart from the range of technical solutions of the utility model, according to technical spirit of the present utility model to any letter made for any of the above embodiments
Single modification, equivalent variations and modification, in the range of still falling within technical solutions of the utility model.
