Brief description of the drawings
Fig. 1 is the structure diagram of the double-deck fan blade into method of pouring of double-deck fan blade provided by the invention；
In figure：
1st, wheel hub；2nd, internal layer blade；3rd, outer blade；4th, circle depth muscle.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right with reference to the accompanying drawings and embodiments
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only used for explaining the present invention, not
For limiting the present invention.
Double-deck fan blade as shown in Figure 1 includes wheel hub 1, internal layer blade 2 and outer layer leaf into method of pouring, the bilayer fan blade
Piece 3, the internal layer blade 2 are set in the outside of wheel hub 1, and the outer blade 3 is set in the outside of internal layer blade 2, it is described into
The method of pouring includes：
Step a, it is respectively provided with the wheel hub 1 and on the Outer blade into cast gate；
Step b, first open at the wheel hub 1 it is described poured into cast gate into traveling, and open after setting time described outer
Lateral lobe on piece it is described into cast gate.
After mold clamping, sprue to it is all it is described carry out plastic cement supply into cast gate, it is first into cast gate on the wheel hub 1
Injection is proceeded by, when plastic cement flows to the end of internal layer blade 2, described on outer blade 3 starts to be molded into cast gate, plastic cement
Blade end is arrived substantially simultaneously at, can ensure that product size index, weight indicator, deformation index, dynamic balancing index accord with
Close and require.
The thickness of the internal layer blade 2 is more than the thickness of the outer blade 3, namely the time of injection internal layer blade 2 is big
In the time of the outer blade 3, therefore, it is necessary to be first molded to wheel hub 1 and internal layer blade 2, and then it can ensure plastic cement
Reach the internal layer blade 2, the end of the outer blade 3 at the same time.
In step a, wire dot system or needle valve type hot runner hot mouth, the outer lobe are used into cast gate at the wheel hub 1
Needle valve type hot runner hot mouth is used into cast gate at piece, the needle valve type hot runner hot mouth includes needle, by controlling the valve
Pin, controls the opening and closing of the needle valve type hot runner hot mouth, and then the injection time of outer blade 3 is controlled
System.
In stepb, the setting time according to the size of the internal layer blade 2, into pouring pressure and described into cast gate ruler
It is very little to be calculated.
When being molded to twi-tier blade, when mould is fabricated structure, the internal layer blade 2 and the outer blade
Circle depth muscle 4 is additionally provided between 3, one end of the remote wheel hub 1 of all inner blades may be contained within the circle
On deep muscle 4, all outer blades 3 are uniformly distributed on the lateral surface of the circle depth muscle 4, described outer in step a
The position that the circle depth muscle 4 is in into cast gate of lateral lobe on piece, reduces injection pressure, is conducive to injection production.
When being molded to twi-tier blade, when mould is insert or composite structure, the internal layer blade 2 and the outer blade
Circle depth muscle 4 is additionally provided between 3, one end of the remote wheel hub 1 of all inner blades may be contained within the circle
On deep muscle 4, all outer blades 3 are uniformly distributed on the lateral surface of the circle depth muscle 4, the outside described in step a
4 side away from the inner blade of circle depth muscle is in into cast gate on blade, turns the potential circle of cold runner into cast gate
Position on deep muscle 4 with the circle depth muscle 4 connects.
The quantity of the Outer blade is multiple, and has spacing between the two neighboring Outer blade, in step a
In, it is both provided with each spacing described in one into cast gate.
Embodiment described above only expresses the several embodiments of the present invention, its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
