Description
Technical field
The utility model relates to casting aluminum rotor die carter packing technique field, especially relates to a kind of casting aluminum rotor die casting frock with degassing function.
Background technology
Due to motor rotor punching sheet grooved difference, the casting aluminum rotor frock of use also will be different.If when rotor punching grooved is open slot, the gas producing in casting aluminum rotor process can be discharged immediately in the place of opening.If when rotor punching grooved is closed slot, as shown in Figure 1,10 is closed slot, in this case, the gas producing in casting aluminum rotor process is just difficult to discharge, and can in rotor aluminum strip, cause pore, tomography, cannot meet motor performance requirement, even cause in rotor aluminium ring, sliver, have pore, major defect that cast aluminium is loose, increased repair rate, the percent defective of motor, electric efficiency reduces, and temperature rise is increased, electric current is large, and electric property can not get good guarantee.
Summary of the invention
The deficiency existing for above-mentioned prior art, the purpose of this utility model is while being to provide a kind of rotor punching grooved to be closed slot, can smoothly the gas producing be discharged, guarantee the casting aluminum rotor die casting frock with degassing function of the quality and performance of motor.
For realizing above-mentioned object, the utility model provides following technical scheme: a kind of casting aluminum rotor die casting frock with degassing function, comprise dummy shaft, patrix, middle cover, counterdie and exhaust cap, between described patrix and counterdie, be socketed with middle cover, described patrix is provided with exhaust cap, between exhaust cap and counterdie, be provided with the dummy shaft that runs through patrix, between described patrix and exhaust cap, be provided with exhaust passage.
The utility model is further set to: the concrete structure of described exhaust passage is: on the patrix between dummy shaft and middle cover, be circumferentially evenly equipped with some steam vents, described exhaust cap is provided with the air discharge duct corresponding with steam vent.
The utility model is further set to: the circular row pore on described patrix has six.
The utility model is further set to: described exhaust cap bottom is evenly equipped with six air discharge ducts corresponding with steam vent.
The utility model is further set to: on described counterdie, be provided with and steam vent oval-shaped inlet opening one to one.
The utility model is further set to: described inlet opening has six.
By adopting technique scheme, the technique effect that the utility model reaches is: by a whole set of tool structure is improved, can effectively solve the exhausting problem of closed slot casting aluminum rotor, the problem that closed slot casting aluminum rotor technique is existed is effectively controlled, improve the reliability of closed slot rotor, its overall structure simply, easily processing, it is very convenient to operate, and there is high practicality, guarantee to a certain extent the yield rate of motor, make the quality of motor have raising to a great extent, and performance also greatly promote.

Specific embodiment
As shown in Figures 2 to 6, for the disclosed a kind of casting aluminum rotor die casting frock with degassing function of the utility model, comprise dummy shaft 1, patrix 2, middle cover 3, counterdie 4 and exhaust cap 5, between described patrix 2 and counterdie 4, be socketed with middle cover 3, described patrix 2 is provided with exhaust cap 5, between exhaust cap 5 and counterdie 4, be provided with the dummy shaft 1 that runs through patrix 4, between described patrix 2 and exhaust cap 5, be provided with exhaust passage 6.
In the present embodiment, the concrete structure of described exhaust passage 6 is: on the patrix 2 between dummy shaft 1 and middle cover 3, be circumferentially evenly equipped with some steam vents 7, described exhaust cap 5 is provided with the air discharge duct corresponding with steam vent 79.Circular row pore 7 on described patrix 4 has six.Described exhaust cap 5 bottoms are evenly equipped with six air discharge ducts 9 corresponding with steam vent 7.
In the present embodiment, on described counterdie 4, be provided with and steam vent 7 oval-shaped inlet opening 8 one to one.Described inlet opening 8 has six.
In the time of assembling, dummy shaft 1 is inserted in the blind hole at middle part of counterdie 4, again patrix 2 is arranged on to middle cover 3 tops, the steam vent of patrix 2 communicates with casting aluminum rotor inner chamber, communicate with the inner chamber of middle cover 3, the through hole of patrix 2 and dummy shaft 1 match, and run through by dummy shaft 1, exhaust cap 5 is arranged on the top of patrix 2, the air discharge duct 9 of exhaust cap 5 is corresponding one by one with the steam vent 7 of patrix 2, make the gas in cast aluminium liquid to enter air discharge duct 9 by steam vent 7, make coordinating between exhaust cap 5 and patrix 2 can form an exhaust passage, so just can allow gas enter exhaust passage and be disposed to the external world.
In the whole technical process of cast aluminium.Rotor core is put into this frock, be then contained in assigned address, make cast aluminium liquid enter the inlet opening 8 of cast aluminium liquid from this frock counterdie 4, complete the casting cycle of whole rotor core, the gas producing in this process, by this frock, can effectively discharge gas extraneous.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
