Description
Technical field
The utility model relates to rotor Low Pressure Casting Technology field, is specifically related to a kind of Motor Rotor Low-pressure Cast Aluminium mould.
Background technology
Along with the continuous progress of electromechanics trade, the versatility of motor changes to specificity gradually, has broken the situation that past same class motor is respectively used to heterogeneity, different occasion.At present, progressively increase along with modernization industry is production-scale, the production equipment matched with it is also towards maximization, high running rate future development.One of voltage levels, high power, Large Copacity, high performance motor important directions becoming development, traditional centrifugal and high-voltage cast-aluminum technique can not meet new technical requirement, the technical advantage of low-voltage cast aluminum technique manifests day by day, its advantage is that the mold filling pressure of aluminium liquid is little, air in die cavity can fully be discharged, finished product dense structure after casting, crystal grain is little, and these process characteristics are highly suitable for the casting of specific type of electric machine rotor.Under this background, a kind of Motor Rotor Low-pressure Cast Aluminium mould of development and Design, meets the technical requirement of low-voltage cast aluminum technique.
Utility model content
Also can meet the technical requirement of low-voltage cast aluminum technique to improve rotor castability, the utility model provides a kind of Motor Rotor Low-pressure Cast Aluminium mould.
The technical scheme that the utility model adopts is: a kind of Motor Rotor Low-pressure Cast Aluminium mould, comprise blade profile assembly, middle mould, lower blade profile assembly and dummy shaft, described upper blade profile assembly is made up of upper padding plate and patrix, upper padding plate and patrix are bolted, the each blade profile chamber of patrix is provided with steam vent, each steam vent is communicated with air exhaust loop, described lower blade profile assembly is made up of lower bolster and counterdie, lower bolster and counterdie are bolted, the each blade profile chamber of counterdie is provided with steam vent, each steam vent is communicated with air exhaust loop, air discharge duct corresponding to patrix and counterdie air exhaust loop is separately communicated with, described dummy shaft is placed in counterdie locating hole, false key is bumped in dummy shaft groove, rotor core is inserted in dummy shaft by false key guiding.
Preferably, described air exhaust loop and the air discharge duct degree of depth are 5-8mm.
Compared with prior art, the beneficial effects of the utility model are: rotor castability is stablized, and cast sturcture is fine and closely woven, and without disconnected bar, the rotor of casting is without waste product.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
In figure: 1. upper padding plate, 2. patrix, 3. dummy shaft, 4. false key, 5. rotor core, mould 6., 7. counterdie, 8. lower bolster, 9. air discharge duct, 10. air exhaust loop, 11. steam vents.
Detailed description of the invention
In order to more clearly the technical solution of the utility model can be understood, below in conjunction with accompanying drawing, the utility model is further illustrated.
A kind of Motor Rotor Low-pressure Cast Aluminium mould as shown in Figure 1, comprise blade profile assembly, middle mould 6, lower blade profile assembly and dummy shaft 3, upper blade profile assembly is made up of upper padding plate 1 and patrix 2, upper padding plate 1 and patrix 2 are bolted, the each blade profile chamber of patrix 2 is provided with steam vent 11, each steam vent 11 is communicated with air exhaust loop 10, lower blade profile assembly is made up of lower bolster 8 and counterdie 7, lower bolster 8 and counterdie 7 are bolted, the each blade profile chamber of counterdie 7 is provided with steam vent 11, each steam vent 11 is communicated with air exhaust loop 10, patrix 2 air exhaust loop 10 respective with counterdie 7 is communicated with corresponding air discharge duct 9, air exhaust loop and the air discharge duct degree of depth are 5-8mm, dummy shaft 3 is placed in counterdie 7 locating hole, false key 4 is bumped in dummy shaft 3 groove, rotor core 5 is inserted in dummy shaft 3 by false key 4 guiding.
During use, Motor Rotor Low-pressure Cast Aluminium mould is arranged on low-voltage cast aluminum machine, post-decompression dried compressed air passed in airtight crucible, compressed air acts on aluminium liquid surface, enters in stalk by aluminium hydraulic pressure, lower mould import is aimed in stalk outlet, aluminium liquid slowly rises and enters counterdie until be full of mold cavity, after the aluminium liquid in die cavity solidifies, and compressed air of draining, aluminium liquid in stalk can be back to again in crucible, so far completes the cast aluminium process of rotor.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
