Description
Technical field
Cast molding technology field is the utility model is related to, more particularly to a kind of gas turbine large thin-wall blade casting is auxiliary
Help molding structure.
Background technology
Gas turbine blades are in irregular shape, complicated, length is larger, and are hollow and thin-walled structure, due to its work
Environment is more severe, and very high requirement is proposed to its structure precision and various aspects of performance.It is at present guarantee blade dimensions processing
Precision is often processed by the way of welding, causes that the globality of blade is poor, and structural strength is affected, and is substantially reduced
The service life of blade.It is big to this gas turbine using full form casting process with the fast development of full form casting process
Type thin wall vane carries out casting, not only can guarantee that the vane size precision but also can guarantee that the overall construction intensity of blade, improves
The service life of blade.But when carrying out model casting, since length of blade is larger, used by model casting shell length compared with
Greatly, in cast, shell is difficult to effectively be fixed and supported, and the model casting to this blade brings very big difficulty.
Utility model content
The purpose of this utility model is that solve the above-mentioned technical problem present in blade model casting, there is provided Yi Zhongjie
Structure is simple and convenient to operate, cost it is relatively low and can obtain good effect gas turbine large thin-wall blade casting auxiliary into
Type structure.
In order to solve the above technical problems, the utility model employ a kind of gas turbine large thin-wall blade casting auxiliary into
Type structure, including the melt pit with certain depth, the sandbox that upper surface is hatch frame, sandbox height are provided with the melt pit
Less than melt pit depth, the shell for blade casting is vertically arranged in sandbox, and sandbox is highly greater than shell length, in sandbox
Fine sand is filled with, fine sand is coated on outside shell, and shell has certain spacing with sandbox bottom, and shell is arranged on to be made of fine sand
Layer of sand on.
In above-mentioned technical proposal, further, the spacing between shell and the sandbox bottom is 50-100mm.
In above-mentioned technical proposal, further, certain gap is provided between the sandbox side wall and melt pit.
In above-mentioned technical proposal, further, the gap between the sandbox side wall and melt pit is 10-30mm.
In above-mentioned technical proposal, further, cushion block is provided between the sandbox and melt pit.
In above-mentioned technical proposal, further, both sides set lifting lug respectively on the sandbox.
Beneficial effect possessed by the utility model：
The utility model is simple in structure, and the shell of casting is fixed support by fine sand, facilitates the casting of blade
Shaping, and coated shell by fine sand, cladding support is provided for shell in cast molding, prevents shell from being poured in blade
Metal fluid produces destruction to shell during type casting moulding, ensures casting quality；The utility model using easy to operate, cost compared with
It is low.
Brief description of the drawings
Fig. 1 is one structure diagram of embodiment in the utility model.
Fig. 2 is two structure diagram of embodiment in the utility model.
In figure：1st, melt pit, 2, sandbox, 3, shell, 4, fine sand, 5, cushion block, 6, lifting lug.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Embodiment one
As shown in Figure 1, the gas turbine large thin-wall blade casting assistant formation structure in the present embodiment, including with one
The melt pit 1 of depthkeeping degree, the sandbox 2 that upper surface is hatch frame is provided with melt pit 1, and 2 height of sandbox is less than 1 depth of melt pit, use
It is vertically arranged in the shell 3 of blade casting in sandbox 2,2 height of sandbox is greater than 3 length of shell, and fine sand is filled with sandbox 2
4, fine sand 4 is coated on outside shell 3, and shell 3 has certain spacing with 2 bottom of sandbox, and shell 3 is arranged on the sand being made of fine sand
On layer.
Preferably, the spacing between 2 bottom of shell 3 and sandbox is 50-100mm.Casting when need by metal fluid from
It is cast in shell under, due to shell irregular structure itself, the bad fixation of shell, and is cast to by metal fluid
When in shell, metal fluid has certain impact force to shell, may be caused to damage to shell in casting, so as to pouring
Type casting moulding quality affects.Using filling fine sand in sandbox in the present embodiment, by fine sand at the same time to shell into
Row cladding and fixed support, solve the problems, such as above, both to have ensure that the feasibility of shell pouring operation, and in turn ensure that well
The Forming Quality of shell casting.
, it is necessary to be taken out through molding product from sandbox after the completion of casting, the casting behaviour of next product is carried out at the same time
Make, it is necessary to the fine sand in sandbox is poured out, just need to hang out sandbox from melt pit at this time.In 2 side wall of sandbox and melt pit 1
Between be provided with certain gap, the gap setting between sandbox side wall and melt pit is 10-30mm, enables sandbox successfully from ground
Hung out in hole.For the purposes of the lifting lug 6 for being used for lifting easy to which sandbox is hung out from melt pit, can be set on sandbox 2.
Embodiment two
In the present embodiment, cushion block 5 is provided between sandbox 2 and melt pit 1；By setting cushion block between sandbox and melt pit
5, height and position of the sandbox in melt pit can be adjusted, while make to keep certain gap between sandbox and melt pit, facilitate sandbox
Lifting.
The fine sand in sandbox is cleared up for convenience at the same time, the bottom plate of sandbox can be arranged to bascule, such as
It is attached using hinging manner between sandbox bottom plate side and sandbox, is fixed between other each sides of bottom plate and sandbox using buckle
Connection, so after sandbox is lifted out from melt pit, unclamps the buckle between bottom plate and sandbox, at this time again hangs sandbox
Rise, you can easily the fine sand in sandbox is poured out, closes buckle when reusing.
The specification and drawings of the utility model are considered illustrative and not restrictive, on the utility model basis
On, those skilled in the art are according to disclosed technology contents, it is not necessary to which performing creative labour can be to some of technologies
Feature makes some and replaces and deform, within the protection scope of the present utility model.
