Abstract
The utility model relates to a mould. In order to solve the technical problem of the mould during centrifugal aluminum casting for the shaftless rotor of a motor, the utility model provides a centrifugal aluminum casting mould for the shaftless rotor of the motor. The centrifugal aluminum casting mould comprises a lower mould, a lower mould base plate, a middle mould above the lower mould and an upper mould above the middle mould, wherein the upper mould is provided with a sprue bush, the middle mould is internally provided with a rotor iron core, and the top of a cast aluminum shaft of the rotor iron core is provided with an air vent cover plate. The centrifugal aluminum casting mould is characterized in that the lower mould and the lower mould base plate are connected in a seam allowance matching manner through; the upper mould and the sprue bush are connected in a seam allowance matching manner; and the air vent cover plate at the top of the cast aluminum shaft is connected with the cast aluminum shaft through threads. The centrifugal aluminum casting mould disclosed by the utility model is simple in structure, low in cost, reasonable in process, and higher in production efficiency and practical efficiency, and has the advantages of preventing an air vent from an aluminum intake phenomenon, increasing the quality of the shaftless rotor and reducing the production cost.
Description
Technical field
The utility model relates to a kind of mould, specifically is meant a kind of electromotor no axis centrifugal aluminum casting for rotor mould.
Background technology
In electromechanics trade, it is most economical not having axle rotor employing centrifugal aluminum casting, therefore in manufacturer's extensive use.The assembling of traditional centrifugal cast-aluminum die is as shown in Figure 1, and mould comprises patrix 4, middle mould 3, counterdie 2 and core insert 12, and core insert 12 is fixed on the rotating disk 1; Counterdie 2 is sitting on the core insert 12, and middle mould 3 is seated on the counterdie 2, and patrix 4 is installed on middle mould 3; Sprue bush 6 is installed on the patrix 4, and patrix 4 and sprue bush 6 are pushed down through upper bolster 7, strain through pull bar 8 between upper bolster 7 and the rotating disk 1; At middle mould 3 inner rotor core 9, the cast aluminium axle top installation vent panels 10 of rotor core installed.High speed rotating through rotating disk injects aluminium by sprue bush, and under centrifugation effect, aluminium liquid is full of die cavity.But above-mentioned mould; We can find out; Patrix 4 adopts two body structures stack with counterdie 2, vent panel 10 with the cast aluminium axle with sprue bush 6, core insert 12, no matter such centrifugal aluminum casting mode structure still in use all brings certain trouble to the operator in manufacturing.Tapering was done easy not matching when patrix 4 was manufactured with counterdie 2 with sprue bush 6, core insert 12, in use, just had folder aluminium phenomenon between patrix 4 and sprue bush 6, core insert 12 and the counterdie; The no axle rotor outward appearance of making like this is undesirable, and vent panel 10 is two body structures with the cast aluminium axle, when moving back the cast aluminium axle; Vent panel 10 is fragile; Casting one does not have the axle rotor, just wastes a vent panel, causes motor cost obviously to increase.
Summary of the invention
The technical problem that mould exists when solving present electromotor no axis centrifugal aluminum casting for rotor, this practical plan provides a kind of electromotor no axis centrifugal aluminum casting for rotor mould.
The technical scheme that the utility model adopted is: a kind of electromotor no axis centrifugal aluminum casting for rotor mould comprises the counterdie on the rotating disk, the patrix on middle mould on the counterdie and the middle mould; Counterdie is pushed down by die shoe, and counterdie and middle mould, middle mould and patrix adopt seam to be connected respectively, and sprue bush is installed on the patrix; Patrix and sprue bush are pushed down by upper bolster; Adopt the pull bar tension between upper bolster and the rotating disk, in middle mould, rotor core is installed, vent panel is installed at the cast aluminium axle top of rotor core; It is characterized in that: be provided with the counterdie backing plate between rotating disk and the counterdie; The counterdie backing plate is fixedly connected with rotating disk, and counterdie and counterdie backing plate are respectively equipped with seam, and counterdie and counterdie backing plate adopt seam to be connected; Described patrix and sprue bush are respectively equipped with seam, and both adopt seam to be connected; Adopt between the vent panel at described cast aluminium axle top and the cast aluminium axle and be threaded.
The beneficial effect of the utility model is, simple in structure, cost is low, and technology is reasonable, and production efficiency and practical efficient are higher, have guaranteed not have in the ventilation hole into aluminium phenomenon, improves and do not have an axle rotor quality, reduced production cost.
