Description
Technical field
The utility model relates to a kind of Novel motor rotor centrifugal casting mould, and it is a kind of rotor centrifugal casting mould of exempting to beat.
Background technology
At present, many apparatus for cast-aluminium rotor of electric machine adopt centrifugal casting, and in aluminium water condensation process, rotor fan blade and balance columns, together with die bonds, during die sinking, need certain active force and carry out the demoulding.Traditional release method is sling together with product by mould, uses locking position (ears or side handles of a utensil) that hammer beats mould repeatedly and produce shaking force and mold deadweight comes die sinking, the demoulding.Owing to repeatedly beaing the locking position of mould, inevitably destruction in various degree or right is caused to mould
rotorcause damage, thus cause whole mould to occur the problem of being out of shape or ftractureing, seriously reduce die life and product quality.And labor strength is large, knocking noise causes certain pollution to environment, inharmonious with the low-carbon environment-friendly production requirement of producing now.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, provides that a kind of structure is simple, labour intensity is low, production efficiency is high, appearance looks elegant, exempts from the Novel motor rotor centrifugal casting mould that beats, product can not damage, die life is long.
The technical solution of the utility model: a kind of Novel motor rotor centrifugal casting mould, comprise patrix, middle mould, counterdie rotor core and die locking mechanism, it is characterized in that being arranged with two cam mould emptiers between patrix in described rotor centrifugal casting mould and middle mould, this cam mould emptier is formed by connecting by ripping bar and cam, and namely cam is arranged on ripping bar lower end;
Cam in two described cam mould emptiers is separately positioned in the notch of left and right side transverse slat of patrix, and touches with the left and right side transverse slat of counterdie respectively.
The patrix effect of this mould forms upper fan blade peace weighing apparatus post, and counterdie effect forms lower fan blade peace weighing apparatus post.
Operating process of the present utility model is as follows
:
1, preheating: first whole set of die and rotor core are put respectively into heating inside box resistance wire furnace and reach technological requirement temperature (rotor core temperature is 660-680 DEG C, and patrix temperature is 400-500 DEG C, and counterdie, middle mould temperature are 150-200 DEG C);
2,
matched moulds:from heating furnace, take out mould and rotor core, according to the order matched moulds of counterdie, rotor core, middle mould, patrix, make it form rotor die cavity, then with screw rod, whole set of die is locked;
3,
cast: after mold-locked, start centrifuge and after reaching certain rotating speed, pour aluminium water into aluminium water from the down gate of patrix;
4,
the demoulding: die sinking after held for some time, take out cast-aluminum rotor, complete the casting process of whole rotor.Wherein,
demoulding principle:adopt cam mould emptier; utilize cam and lever (ripping bar) and active force and reaction force principle; in cam rotation process; form very large tensile force between cam and middle mould, because middle mould is fixed, thus tensile force passes to patrix; the extruding force that patrix is subject to upwards is separated with cast-aluminum rotor automatically; realize demoulding object, then whole rotor is taken out from casting mould, complete the casting process of whole rotor.Then matched moulds puts into rotor core, repeats aforesaid operations step, enters the production process of pouring into a mould next cast-aluminum rotor.
The utility model improves prior art, namely in existing mold, sets up cam mould emptier, namely between patrix and middle mould, is arranged with two cam mould emptiers; Cam and lever (ripping bar) and active force and reaction force principle is utilized to carry out the demoulding, this mould is owing to adopting cam, the demoulding of lever (ripping bar) mechanism, repeatedly beat compared with mould profile with traditional, whole knockout course simply, easily and easily realizes, both labor strength was reduced, turn avoid mould due to the damage of repeatedly beaing with hammer, substantially prolongs die life, eliminate the pollution caused owing to beaing NOISE ON ENVIRONMENT.The utility model (production cast-aluminum rotor) labour intensity is low, and production efficiency is high, and product appearance is attractive in appearance, and inherent quality is excellent, and motor performance is excellent.

Detailed description of the invention
With reference to above-mentioned accompanying drawing, a kind of Novel motor rotor centrifugal casting mould, comprise patrix 1, middle mould 2, counterdie 3 rotor core 4 and die locking mechanism, it is characterized in that being arranged with two cam mould emptiers 5 between patrix (1) in described rotor centrifugal casting mould and middle mould 2, this cam mould emptier (5) is formed by connecting by ripping bar 51 and cam 52, and namely cam 52 is arranged on ripping bar 51 lower end;
Cam 52 in two described cam mould emptiers 5 is separately positioned in the notch of left and right side transverse slat of patrix 1, and touches with the left and right side transverse slat of counterdie 3 respectively.The patrix effect of this mould forms upper fan blade peace weighing apparatus post, and counterdie effect forms lower fan blade peace weighing apparatus post.
Operating process of the present utility model is as follows
:
1, preheating: first whole set of die and rotor core 4 are put respectively into heating inside box resistance wire furnace and reach technological requirement temperature (rotor core temperature is 660-680 DEG C, and patrix temperature is 400-500 DEG C, and counterdie, middle mould temperature are 150-200 DEG C);
2,
matched moulds:from heating furnace, take out mould and rotor core 4, according to the order matched moulds of counterdie 3, rotor core 4, middle mould 2, patrix 1, make it form rotor die cavity, then use die locking mechanism (screw rod) whole set of die to be locked;
3,
cast: after mold-locked, start centrifuge and after reaching certain rotating speed, pour aluminium water into aluminium water from the down gate 11 of patrix;
4,
the demoulding: die sinking after held for some time, take out cast-aluminum rotor, complete the casting process of whole rotor.Wherein,
demoulding principle:adopt cam mould emptier; utilize cam and lever (ripping bar) and active force and reaction force principle; in cam rotation process; form very large tensile force between cam and middle mould, because middle mould is fixed, thus tensile force passes to patrix; the extruding force that patrix is subject to upwards is separated with cast-aluminum rotor automatically; realize demoulding object, then whole rotor is taken out from casting mould, complete the casting process of whole rotor.Then matched moulds puts into rotor core, repeats aforesaid operations step, enters the production process of pouring into a mould next cast-aluminum rotor.
With reference to figure 3, last die sinking, ejection phase is cast at rotor, overhead cam 52 is overlapped with ripping bar 51, then to ripping bar 51 end applying power F1 upwards, due to lever principle, rotate centering mould 2 at the cam 52 of ripping bar 51 other end and produce very large tensile force F2, when middle mould 2 is fixing, due to active force and reaction force, thus tensile force F2, pass to patrix, patrix 1 is made to be subject to upwards very large extruding force F3 (knockout press) and to be automatically separated with cast-aluminum rotor, complete die sinking, knockout course, take out cast-aluminum rotor, complete the casting process of whole rotor.Then matched moulds puts into the production process that rotor core enters next rotor.The cruelty of the traditional demoulding of good solution beats the secondary injury and security hidden trouble that cause mould.
