Description
Technical field
This utility model relates to motor manufacturing technology equipment technology field, particularly relates to be applicable to high-voltage AC motor thickness end
A kind of centrifugal cast-aluminum die of ring.
Background technology
Produced centrifugal force when centrifugal aluminum casting is to utilize workpiece to rotate, is full of aluminum water top ring, lower loop and owns
Flute profile, thus obtain a kind of method of complete cast-aluminum rotor.This is a kind of method that China's electromechanics trade uses the earliest.
But, for the end ring thickness large and medium-sized cast-aluminum rotor iron core more than 60mm, traditional centrifugal cast-aluminum die relies on
Rounding type ingate enters aluminum, and it cannot ensure cast-aluminum rotor quality.Facts have proved: the large and medium-sized motor cast out with this mould
Cast-aluminum rotor iron core, there is large-area shrinkage cavity and porosity in its thick end ring, iron core aluminium weight is not enough, and aluminum strip in grooved hold
It is easily generated broken strip, slice.Then motor aluminum consumption, iron loss can be caused to increase, and efficiency reduces, torque reduction and revolutional slip and temperature rise
Increase, severely impacted the quality of motor.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, it is provided that a kind of centrifugal cast-aluminum die.Solve
The prior art middle-end ring thickness cast-aluminum rotor more than 60mm relies on the rounding type ingate to enter aluminum during centrifugal casting, goes out
The problem of existing end ring shrinkage cavity and porosity.Can ensure that the aluminum weight of cast-aluminum rotor iron core end ring, improve the qualification rate of product.
The purpose of this utility model is achieved through the following technical solutions:
A kind of centrifugal cast-aluminum die, including diverter and cast aluminium axle, diverter and cast aluminium axle be fixed on upper die and lower die it
Between, the periphery of cast aluminium axle is arranged with rotor core, and upper mold is provided with the end ring die cavity for molding iron core end ring, end ring die cavity towards
The one side of diverter has a point lobe ingate.
Preferably, described point of lobe ingate has been evenly distributed 4 to 6 gap.
It is further preferred that the quantity of described gap is four.
Preferably, described point of lobe ingate is opened in the bottom of end ring die cavity.
It is further preferred that described point of lobe ingate is opened at lower the 1/3 of end ring die cavity.
Preferably, the outward flange shape of described diverter is identical with the bottom shape of the iron core end ring of required molding.
It is further preferred that the iron core end ring of required molding includes outer end anchor ring and inner anchor ring, outside described diverter
The cross section at edge is oblique line shape, and the angle of inclination of oblique line is identical with the angle of inclination of inner anchor ring.
This utility model has the advantages that
A kind of centrifugal cast-aluminum die that this utility model provides, is particularly suited for the iron core end ring thickness high pressure more than 60mm
Motor.By offering a point lobe ingate at end ring die cavity, accelerate effective flow velocity of aluminum liquid, aluminum liquid can be made to be rapidly filled with end ring
Die cavity is to ensure aluminum weight, it is to avoid aluminum in the end ring shrinkage cavity and porosity caused because flow rate of aluminium liquid is difficult to the most slowly fill and iron core grooved
Bar broken strip, the problem of slice, improve the qualification rate of product.
Further, by point lobe ingate being opened in the bottom of end ring die cavity, it is easier to the removing of aluminium scrap in end ring, can
To obtain size more standard, the internal more preferable end ring of roughness.
Further, owing to the outward flange shape of diverter is identical with the bottom shape of the iron core end ring of required molding, from
And relying on the interior hoop section in the ring-like chamber of outward flange forming ends of diverter, its shape can preferably control to enter at aluminum liquid stream
The Forming Quality in the ring-like chamber of Cheng Zhongduan, makes the interior hoop section of end ring die cavity be easier to molding, it is ensured that the chi of interior hoop section
Very little, smooth bottom the iron core end ring that so casts out.
Accompanying drawing explanation
Fig. 1 is the structural representation of centrifugal cast-aluminum die provided by the utility model.
Wherein: 1 is diverter；2 is cast aluminium axle；3 is upper mold；4 is lower mold；5 is rotor core；6 is end ring die cavity；7 are
Divide lobe ingate.
Detailed description of the invention
Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is only used for explaining this practicality
Novel, it is not intended to limit scope of the present utility model.
Seeing Fig. 1, this utility model provides a kind of centrifugal cast-aluminum die, including diverter 1 and cast aluminium axle 2, diverter 1
With cast aluminium axle 2 is fixed between upper mold 3 and lower mold 4, the periphery of cast aluminium axle 2 is arranged with rotor core 5, and upper mold 3 is provided with for becoming
The end ring die cavity 6 of shaped iron core end ring, end ring die cavity 6 has a point lobe ingate 7 towards the one side of diverter 1.
Preferably, described point of lobe ingate 7 has been evenly distributed 4 to 6 gap.
It is further preferred that the quantity of described gap is four.
This centrifugal cast-aluminum die is particularly suited for the high-voltage motor that the iron core end ring of rotor is thicker, as big in iron core end ring thickness
High-voltage motor in 60mm.Its principle is: aluminum liquid by centrifugal force promote by the top of diverter 1 and circumference quickly flow into into
The split-type cast gate of upper mold 3, is full of at end ring die cavity 6, then is entered the rotor core 5 of motor by the end ring die cavity 6 of upper mold 3 and fill
Full, and then flow into lower mold 4 and be rapidly filled with, complete cast aluminium process.
Here, by offering a point lobe ingate 7, accelerate effective flow velocity of aluminum liquid, aluminum liquid can be made to be rapidly filled with end ring
Die cavity 6 is to ensure aluminum weight, it is to avoid aluminum in the end ring shrinkage cavity and porosity caused because flow rate of aluminium liquid is difficult to the most slowly fill and iron core grooved
Bar broken strip, the problem of slice, improve the qualification rate of product.
Preferably, described point of lobe ingate 7 is opened in the bottom of end ring die cavity 6.It is further preferred that described point of lobe ingate
7 are opened at lower the 1/3 of end ring die cavity 6.
Here, by offering a point lobe ingate 7, and it is opened at lower the 1/3 of end ring die cavity 6, and in prior art
The full cast gate directly opened by rounding type ingate to the 2/3 of end ring thickness is compared, it is easier to the removing of aluminium scrap in end ring, permissible
Obtain size more standard, the internal more preferable end ring of roughness.Solve the full cast gate of cast-aluminum rotor that in prior art, end ring is thick to enter
Aluminum, cast gate offer too high and cause end ring to occur shrinkage cavity and porosity and iron core aluminum strip broken strip, slice etc. have a strong impact on the quality of motor
Problem.
In prior art, the peripheral portion of diverter 1 is divided into arc, does not have the effect of auxiliary end ring die cavity 6 molding.Excellent
Selection of land, in this utility model, the bottom shape phase of the outward flange shape of described diverter 1 and the iron core end ring of required molding
With.
It is further preferred that the iron core end ring of required molding includes outer end anchor ring and inner anchor ring, outside described diverter 1
The cross section at edge is oblique line shape, and the angle of inclination of oblique line is identical with the angle of inclination of inner anchor ring.Thus rely on outside diverter 1
The interior hoop section of edge formation end ring die cavity 6, its shape can preferably control the one-tenth of end ring die cavity 6 during aluminum liquid stream enters
Type quality, makes the interior hoop section of end ring die cavity 6 be easier to molding, it is ensured that the size of interior hoop section, so casts out
Smooth bottom iron core end ring.
