Abstract
The utility model discloses a motor rotor centrifugal aluminium-casting mould adopting a double-cylinder positioning structure, aiming at providing the motor rotor centrifugal aluminium-casting mould which has simple structure, easy manufacture and high casting precision and saves casting material. The motor rotor centrifugal aluminium-casting mould consists of an upper mould ring, a middle mould and a lower mould ring; the central axis of the upper mould ring, the middle mould and the lower mould ring are positioned on a same axis and sequentially connected up and down, and the middle mould consists of two half cylinders which are subdivided along the central axis, and adopts the double-cylinder positioning structure.
Description
Technical field
The utility model relates to a kind of cast-aluminum die, and specifically, the utility model relates to a kind of centrifugal cast-aluminum die.
Background technology
The centrifugal cast-aluminum die of the rotor of prior art is made up of patrix circle, middle mould and counterdie circle, and patrix circle, middle mould, counterdie circle central axis are positioned on the same axis and are linked in sequence up and down; Middle mould is made up of two semicircular cylinders along the central axis subdivision, and mould is realized circumferentially location by the taper fit that it is arranged on the faying face in two semicircular cylinders, and patrix circle, counterdie circle and middle mould are by the taper fit realization axial location of its end.The centrifugal cast-aluminum die of the rotor of this structure can satisfy the needs of the centrifugal cast aluminium of rotor of general precision.The deficiencies in the prior art part is: the taper of two semicircular cylinders of middle mould by on faying face in conjunction with the time, because the characteristics of wedge structure self, the binding site of each two semicircular cylinders is not necessarily consistent, and the mould endoporus may not justified in making, influences casting accuracy; Two semicircular cylinders in conjunction with the time gapped at the faying face place, during spun casting, the aluminium water of fusing flows out from gap location, causes waste of material; Complex structure, the accuracy of manufacture requires high, the manufacturing cost height.
The utility model content
The utility model is at the deficiencies in the prior art, proposes a kind of simple in structurely, easy to manufacture, and the casting accuracy height is saved the centrifugal cast-aluminum die of rotor of founding materials.
The utility model is achieved through the following technical solutions technical goal.
The centrifugal cast-aluminum die of the rotor of bicylindrical location structure, it is made up of patrix circle, middle mould, counterdie circle; Described patrix circle, middle mould, counterdie circle central axis are positioned on the same axis and are linked in sequence up and down; Mould two ends cylindrical is realized axial location with patrix circle, counterdie circle by the taper fit of its end respectively in described; Mould is made up of two semicircular cylinders along the central axis subdivision in described, and its improvements are: mould adopts the bicylindrical location structure in two semicircular cylinders on faying face.
Middle mould endoporus in of the present utility model after the each combination of mould all is the same, has guaranteed casting accuracy; In two semicircular cylinders of mould in conjunction with the time do not have the gap at the faying face place, during spun casting, the aluminium water of fusing can not flow out, and can not cause the founding materials waste.
The utility model compared with prior art has following good effect:
1, simple in structure, easy to manufacture, cost is lower;
2, casting accuracy height;
3, save founding materials.
Description of drawings
Fig. 1 is a structural profile schematic diagram of the present utility model.
Fig. 2 is the cutaway view of Fig. 1.
Fig. 3 is the prior art constructions generalized section.
Fig. 4 is the cutaway view of Fig. 3.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
A kind of centrifugal cast-aluminum die of rotor that adopts the bicylindrical location structure shown in the drawings, it is the instantiation that is applied in the 5.5KW marine service motor, it is by patrix circle 1, middle mould 2, counterdie circle 3; Patrix circle 1, middle mould 2, counterdie circle 3 central axis are positioned on the same axis and are linked in sequence up and down, and middle mould 2 is made up of two semicircular cylinders along the central axis subdivision, and mould 2 adopts two Φ, 10 cylinder location structures in two semicircular cylinders on faying face.
The utility model is simple in structure, and is easy to manufacture, the casting accuracy height, two semicircular cylinders of middle mould in conjunction with the time do not have the gap at the faying face place, during spun casting, the aluminium water of fusing can not flow out, and can not cause the founding materials waste.
