Abstract
The utility model relates to a mold for centrifugal aluminum casting of a cage-type rotor of a motor, the mold for centrifugal aluminum casting of the cage-type rotor of the motor comprises an overlying cushion type mold, a diverter and a false axis, wherein the diverter is located at an upper portion of the overlying cushion type mold, the diverter and the overlying cushion type mold are connected through threads, a lower portion of the diverter is provided with a hoisting screw hole, an upper portion of the false axis is provided with a liquid coolant filling hole. The mold for centrifugal aluminum casting of the cage-type rotor of the motor has properties of simple structure, good processing manufacturability, low manufacturing cost, convenient overlying operation of a rotor punching sheet and reliable punching sheet compaction, can complete withdrawal of the false axis after a centrifugal aluminum casting machine stops rotation about 10 minutes, can guarantee quality of the aluminum casting rotor and realizes safe operation, fast and high efficient mass production.
Description
Technical field
The utility model relates to a kind of motor cage-type rotor centrifugal cast-aluminum die.
Background technology
The dummy shaft of apparatus for cast-aluminium rotor of electric machine manufacturing is used for that iron core laminates, iron core heating and iron core centrifugal aluminum casting.In existing technology, dummy shaft is made up of upper press cover, straight key, dummy shaft, lower cover, outer-hexagonal screw, rotor core.When the dummy shaft of this structure was used for rotor punching and laminates, punching was packed under pressured state and is made the outer-hexagonal screw that screws up with a wrench, and operation is very inconvenient.After particularly centrifugal aluminum casting was accomplished, because the foundry goods real-time temperature is more than 500 ℃, the operator can not use spanner to unscrew the outer-hexagonal screw and dismantles upper press cover near foundry goods; Also can not withdraw from dummy shaft fast; So the whole cast aluminium operating time is long, and inefficiency can not be realized producing in batches.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and operation compresses the dummy shaft assembly that withdraws from fast under quick reliable, the condition of high temperature when providing a kind of rotor punching to laminate, thereby realizes that casting aluminum rotor is efficient and produce in batches.
In order to realize above purpose, the technical scheme of the utility model is: it comprises and laminates pad mould, current divider, dummy shaft.Current divider places the top that laminates the pad mould, and current divider fills up mould through being threaded with laminating, and is provided with the lifting screw in the bottom of current divider.
The top of said current divider is provided with screwed hole, and dummy shaft links together through the thread segment and the current divider of bottom,
The height of said current divider is got H=80mm～120mm; Diameter is φ 80mm～φ 150mm.
In order to be beneficial to the cooling of dummy shaft, be provided with the cooling fluid hand-hole on the top of said dummy shaft.
Circumference is directed when being inserted in dummy shaft in order to be beneficial to punching also takes out easily, is provided with straight key between said dummy shaft and the punching, and straight key embeds in the dummy shaft keyway.
In order to lock punching, be provided with trim ring on the top of said dummy shaft, be provided with the locking square cotter on the top of trim ring, in order to be beneficial to operation, be provided with straight trough with the position that the locking square cotter cooperates at dummy shaft.
Said straight trough is of a size of wide 8～14mm, dark 5～8mm.
Compared with present technology the utility model has the following advantages:
The utility model is simple in structure, processing technology good, low cost of manufacture, rotor punching laminate the dummy shaft easy to operate, that punching compresses reliably, the centrifugal aluminum casting machine stops the rotation can withdraw from after back about 10 minutes fully, guarantee the cast-aluminum rotor quality, realize safety operation, quickness and high efficiency and batch process.

Fig. 3 is the utility model structural representation when centrifugal casting.
The specific embodiment
Combine the embodiment of Fig. 1 to further describe in the face of the present invention down:
Referring to accompanying drawing, it comprises and laminates pad mould 1, current divider 2, dummy shaft 4, shunting; 2 place laminate the pad mould 1 top; Top at current divider 2 is provided with screwed hole, and dummy shaft links together through the thread segment and the current divider 2 of bottom, is provided with the lifting screw in the bottom of current divider 2; It is 100mm that the height of current divider is got H, diameter phi 80mm.In order to be beneficial to the cooling of dummy shaft 4; Be provided with the cooling fluid hand-hole on the top of dummy shaft 4, circumference is directed when being inserted in dummy shaft 4 in order to be beneficial to punching also takes out easily, between punching and dummy shaft 4, is provided with straight key 5; Straight key 5 embeds in the keyway of dummy shaft 4; In order to lock punching, be provided with trim ring 6 on the top of dummy shaft 4, be provided with locking square cotter 7 on the top of trim ring.
More than be a kind of embodiment of the utility model, a preferred example.The scope that the utility model application is asked for protection has more than and is limited to said embodiment.All technical schemes with the present embodiment equivalence all belong to the protection domain of the utility model.
