Abstract

The invention discloses an aluminum die for casting of motor rotors. The aluminum die is characterized by comprising an upper die, a lower die, a middle joint and a taper key positioning shaft. The inner middle of the upper die is provided with a circular groove, the lower die is internally provided with a circular groove identical to that of the upper die, the middle joint is arranged between the circular grooves of the upper die and the lower die, and the taper key positioning shaft penetrates through the middle joint to be arranged between the upper die and the lower die. The aluminum die for casting of the motor rotors has the advantages that air, liquid aluminum and residual gas in the die is effectively discharged, shrinkage, cold shut and the like in ejection of the rotors are reduced, rotor casting quality is improved, high ejection efficiency is achieved, and production efficiency of the motor rotors is improved.

Description

A kind of rotor casting aluminum dipping form
Technical field
The present invention relates to aluminium casting, particularly relate to a kind of rotor casting aluminum dipping form.
Background technology
In prior art, rotor is in press casting procedure, and moulding die pore design used is unreasonable, cause aluminium casting rotor to produce the defect such as shrinkage cavity, cold shut, had a strong impact on product quality, simultaneously when the demoulding, although operation is simple, labour intensity is high, inefficiency.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of rotor casting aluminum dipping form, air in mould and aluminium water residual gas are effectively got rid of, reduce the excessive phenomenons such as the shrinkage cavity of rotor when the demoulding, cold shut, improve the castability of rotor, demoulding efficiency is high simultaneously, improves the production efficiency of electronics rotor.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of rotor casting aluminum dipping form, comprise upper die and lower die, middle node and taper key locating shaft, described patrix inside middle is provided with circular groove, described counterdie inside arranges the circular groove identical with patrix, described middle node is arranged between patrix and counterdie circular groove, and described taper key locating shaft is arranged on upper and lower mould through middle node.
In the present invention's preferred embodiments, described patrix inside is also provided with bar-shaped trough, and described bar-shaped trough is 12, with patrix center for axle center, carries out 360 ° uniform.
In the present invention's preferred embodiments, described patrix inside arranges the bar-shaped trough identical with patrix.
In the present invention's preferred embodiments, described patrix and counterdie end face are provided with steam vent, and described steam vent diameter from large to small.
In the present invention's preferred embodiments, described steam vent and bar-shaped trough are arranged uniformly at intervals.
In the present invention's preferred embodiments, the fit tolerance of described middle node and patrix Baltimore groove and counterdie Baltimore groove is+0.05mm ~+0.08mm.
The invention has the beneficial effects as follows: a kind of rotor casting of the present invention aluminum dipping form, air in mould and aluminium water residual gas are effectively got rid of, reduce the excessive phenomenons such as the shrinkage cavity of rotor when the demoulding, cold shut, improve the castability of rotor, demoulding efficiency is high simultaneously, improves the production efficiency of electronics rotor.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:

In above-mentioned, described taper key locating shaft 4 is through middle node 2, and when the demoulding, take off taper key locating shaft 4, middle node 2 inner chamber leaves the hollow shaft with middle node 4 same shape.
In one embodiment, described patrix 1 inside is also provided with bar-shaped trough 12, and described bar-shaped trough 12 is 12, with patrix 1 center for axle center, carries out 360 ° uniform.
In one embodiment, described counterdie 2 inside arranges the bar-shaped trough 12 identical with patrix 1.
In one embodiment, described 1 patrix and counterdie 2 end face are provided with steam vent 13, and described steam vent 13 diameter from large to small, ensures that electronics rotor neither produces pore when mold, can not produce cold shut defects again.
In one embodiment, described 13 steam vents and bar-shaped trough 12 are arranged uniformly at intervals.
In one embodiment, described middle node 3 is+0.05mm ~+0.08mm with the fit tolerance of patrix circular groove 11 and counterdie circular groove 11.
The invention has the beneficial effects as follows: a kind of rotor casting of the present invention aluminum dipping form, air in mould and aluminium water residual gas are effectively got rid of, reduce the excessive phenomenons such as the shrinkage cavity of rotor when the demoulding, cold shut, improve the castability of rotor, demoulding efficiency is high simultaneously, improves the production efficiency of electronics rotor.
