Abstract
The invention relates to a die, and aims to solve the technical problem in a conventional die for centrifugally casting aluminium to a shaftless rotor of a motor. The practical scheme is that a centrifugal aluminium casting die for a shaftless rotor of a motor is provided, and comprises a low die, a lower die bearing plate, a middle die and an upper die, wherein the lower die and the lower die bearing plate are arranged on a turntable; the middle die is arranged on the lower die; the upper die is arranged on the middle die; a sprue bushing is mounted on the upper die; a rotor core is mounted in the middle die; and a ventilation hole cover plate is mounted at the top of an aluminum casting shaft of the rotor core. The centrifugal aluminum casting die is characterized in that the lower die and the lower die bearing plate are matched and connected through a spigot; the upper die and the sprue bushing are matched and connected through a spigot; and the ventilation hole cover plate at the top of the aluminum casting shaft is in threaded connection with the aluminum casting shaft. The centrifugal aluminum casting die has a simple structure, is low in cost, reasonable in process, and higher in production efficiency and practical efficiency, ensures the aluminum cannot enter into the ventilation hole, improves the shaftless rotor quality, and reduces the production cost.
Description
?
Technical field
The present invention relates to a kind of mould, specifically refer to 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.Traditional centrifugal cast-aluminum die assembling as shown in Figure 1, mould comprises patrix 4, middle mould 3, counterdie 2 and core insert 12, core insert 12 is fixed on the rotating disk 1, and counterdie 2 is sitting on the core insert 12, and middle mould 3 is seated on the counterdie 2, at middle mould 3 patrix 4 is installed, sprue bush 6 is installed on the patrix 4, and patrix 4 and sprue bush 6 are pushed down by upper bolster 7, strain by 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 rotation by rotating disk is injected aluminium by sprue bush, and under centrifugation effect, aluminium liquid is full of die cavity.But above-mentioned mould, we as can be seen, 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 have 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 solution adopted in the present invention is: a kind of electromotor no axis centrifugal aluminum casting for rotor mould, comprise the counterdie on the rotating disk, patrix on middle mould on the counterdie and the middle mould, counterdie is pushed down by die shoe, counterdie and middle mould, middle mould and patrix adopt seam to be connected respectively, 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 fixedlyed 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 invention has the beneficial effects as follows that simple in structure, cost is low, technology is reasonable, and production efficiency and practical efficient are higher, has guaranteed not have in the air vent into aluminium phenomenon, improves and does not have the axle rotor quality, has reduced production cost.
