The key technology of machine, it must be ensured by effective technological measure, ensure that degree of balance requirement is needed using various technological measures
Carry throughout.Prior art manufacture this kind of rotary part when, it is necessary to by the fourth of the twelve Earthly Branches press operation fan blade is connected with rotating shaft and rotor,
Not only technique is cumbersome, it is also possible to can cause the vibration problem caused because rotary part balance index is not up to standard.
The content of the invention
The invention solves the problems that one of problem be to overcome to be made because the fourth of the twelve Earthly Branches presses fan blade and rotating shaft and rotor in the prior art
Into rotary part balance problem not up to standard, there is provided a kind of good, the simple for production rotary part with fan blade rotor of balance.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of rotary part with fan blade rotor, including fan blade, rotor and rotating shaft, the rotor are socketed on the rotating shaft periphery,
The fan blade is formed at the periphery of the rotor and the rotating shaft by injection, and turns into the rotor and the rotating shaft simultaneously
Integrally.
Preferably, the fan blade, rotor and rotating shaft are coaxial, and the fan blade includes some blades being circumferentially all provided with.
The invention solves the problems that another problem be to provide a kind of injection mold, the mould be used for manufacture it is above-mentioned band fan blade turn
The rotary part of son.The technical scheme for solving the problem is：
The injection mold that above-mentioned rotary part is used is prepared, it includes fixed half and moving half, is configured with after cover half and dynamic model matched moulds

The processing step for preparing the rotary part with fan blade rotor as shown in Figure 1 is：
（1）As shown in figure 5, during model rotor 81 inserted into fan blade injection mold a under die opening state, injection moulding after matched moulds, then
Die sinking, takes out the casting a with simulation；Model rotor 81 is preferably and the shape class of rotor 8 in the rotary part with rotor fan blade
Seemingly, but can be from blade remove column or approximate column；
（2）Model rotor 81 in removal casting a, the bucket core corresponding with injection mold a to fan blade in casting a is marked
Note；The method for removing model rotor 81 is preferably：Be selected into the screw of model rotor 81 with its internal diameter identical screw, then
Withdrawing departs from the fan blade of casting a to model rotor 81 backward, describes for convenience, and the fan blade of casting a is referred to as to simulate fan blade
107。
（4）Static balance detection is carried out to simulation fan blade 107；
（5）According to step（4）Testing result injection mold a is repaired a die, until the fan blade of the casting a being molded by reach it is quiet
Untill balance；The preferred method that repairs a die is for counterweight method.
（6）Rotating shaft locating core 12 is installed in injection mold a, injection mold b is obtained, is molded using injection mold b, obtain
Casting b with fan blade rotor.Injection mold b is above-mentioned injection mold（Mould i.e. as shown in Figure 2-5）, when being molded,
Under die opening state, rotating shaft 9 and rotor 8 are inserted the post-receiving chamber 12 of rotating shaft locating core 12 and the rotor chamber of dynamic mould core 13 respectively
In 131, injection moulding after matched moulds, after being molded through pressurize cooling, due to replying the effect of rubber 5, the A-A die joints of cover half（Position
Between the solid plate 7 and fixed mold 14 of cover half）It is first switched on, subsequent B-B die joints（Positioned at the cover half intermediate plate of cover half
Between 16 and the moving platen 17 of dynamic model）It is opened, starts injection machine liftout tank, by push pedal 23, push rod 19 and pushing out casting b；
Spot pouring mouth waste material is pressed from both sides out in A-A die joints.
By Fig. 2 and Fig. 5, and above-mentioned can be understood as：The injection mold a that injection casting a is used is not except using rotating shaft
Outside locating core 12, remaining structure is and step（1）Middle mould is identical.Specifically, during injection, under die opening state, using model rotor
81 replace step（6）In rotor 8, be placed in the post-receiving chamber 12 of rotating shaft locating core 12, then mold-closing injection, obtain to casting
Part a is made up of fan blade and model rotor 81.
Step（4）In to simulation fan blade 107 carry out static balance detection can use other method known in the art, but
Following device and method is used in the present embodiment：
The static balance device that uses of detection is guide tracked static balancing frame as shown in Figure 6, it include two it is arranged in parallel
Guide rail 101, each top of guide rail 101 has edge of a knife chi 102, and two ends of edge of a knife chi 102 are located in same level, edge of a knife chi
Plug 105 is connected with 102, simulation fan blade 107 is socketed on the plug 105.The bottom of each guide rail 101 is respectively provided with smoothing
Cone 104, the smoothing cone 104 can adjust the level height of edge of a knife chi 102.Specifically, smoothing cone 104 has fine thread.
Additionally, the guide tracked static balancing frame also includes base 103.
In order to reduce measurement error, the interference fit of plug 105 has locating core 106, further, locating core 106 and plug
105 are preferably formed using duralumin rod turning, and use hot jacket method interference fit.
Before detection, smoothing 104 pairs of guide tracked static balancing frame correction levels of cone are first passed through：Level meter is inclined cross in two edges of a knife
On chi 102, the desirable level degree of working face is obtained by adjusting the smoothing cone 104 with fine thread.By mould after the completion of correction
Intend fan blade 107 and be placed on locating core 106, gently switch simulates the blade of fan blade 107, plug 105 is made on two edge of a knife chis 102
Repeatedly roll（Frictional force is minimum）.Note observing blade label, if simulation fan blade 107 is gone up at an arbitrary position to stop turning at random
Dynamic, then balance index must be qualified；If a certain label blade is always at the downward position of vertical when simulation fan blade 107 is static,
Then show that the polar moment of inertia at certain particle relative rotation center of the blade is bigger than normal compared with the relative position of other blades.
What above-mentioned counterweight method repaired a die concretely comprises the following steps：
If the simulation fan blade 107 for measuring is uneven, in step（4）What is measured is always at that downward blade opposite leaf of plummet
Appropriate counterweight mud, repeat step are stained with the outer most edge of piece（4）Operation, until balance.Then according to the position of counterweight mud,
In injection mould bucket core（The present embodiment is specially dynamic mould core 13）Corresponding position make the filing duplicate removal of equivalent weight, carry out weight
New die trial is until the simulation test passes of fan blade 107.
After repairing a die successfully, implement above-mentioned steps（6）, rotary part of the casting with fan blade rotor.
The above is only the preferred embodiment of the present invention, it is noted that come for those skilled in the art
Say, on the premise of the technology of the present invention principle is not departed from, some improvement and deformation can also be made, these are improved and deformation also should
It is considered as protection scope of the present invention.
