Abstract

An electric motor rotor die-casing mold used for manufacturing a cast-aluminum rotor of an electric motor includes an upper template, an upper die, a middle die, a lower die, a stamping ring, a dummy shaft, a tightening ring, a taper key, an inner hexagon screw, a connecting guide pillars and other parts. No vent channel is formed on the lower surface of the upper template, but an annular casting fin overflow groove and a plurality of radial vent channel which are communicated mutually and evenly distributed circumferentially are formed on the upper surface of the upper template; and two annular casting fin overflow groove, as well as a plurality of radial vent channel which are communicated mutually and evenly distributed circumferentially, are respectively formed on upper and lower spigots where the upper die and the lower die are matched with the middle die, that is, on the upper and the lower spigots where the lower surface of the upper die and the upper surface of the lower die are matched with the middle die. The vent structure of the electric motor rotor die-casing mold has obvious advantages of smooth and rapid exhaust and good exhaust effect.

Description

A kind of cast die of electric machine rotor tool

Technical field

The utility model relates to a kind of cast die of electric machine rotor tool that apparatus for cast-aluminium rotor of electric machine is used of making.

Background technology

At present, domestic being used for makes, the die casting that the micro-machine cast-aluminum rotor is used, for reducing the generation of die casting pore, improve the percentage of A-class goods of apparatus for cast-aluminium rotor of electric machine die casting, general to have on the lower surface of cast die of electric machine rotor tool cope match-plate pattern all that the degree of depth is about the annular row air drain of 0.2mm and the radial air discharge duct of some circumference uniform distributions connecting with it, when being beneficial to the die casting rotor, the discharge of gas in the die casting die cavity, but because this air discharge duct is opened on the cope match-plate pattern lower surface, air discharge duct is from the die cavity distance, and air discharge duct distributes and concentrates, quantity is few again, so this cast die of electric machine rotor tool, exist exhaust velocity slow, exhaust is insufficient, weak effect, the rotor die casting pore of being produced is many, the drawback that the percentage of A-class goods is low, to being used for the remain silent rotor die casting of groove of the bigger elongated shape of die casting major diameter ratio, this drawback is more obvious especially.

Summary of the invention

The existing exhaust velocity of present cast die of electric machine rotor tool is slow, exhaust is insufficient, weak effect in order to solve, the drawback that rotor die casting pore is many, the percentage of A-class goods is low of being produced, the utility model provides a kind of exhaust performance good cast die of electric machine rotor tool, and it can solve the existing problem of traditional die casting well.

The technical scheme that the utility model technical solution problem is adopted is: a kind of cast die of electric machine rotor tool, and its patrix is connected guide pillar with cope match-plate pattern by the soket head cap screw connection and it is combined, and patrix can slide up and down along connecting guide pillar; Counterdie can be fixed on the die casting machine by the pressing mold circle; Cope match-plate pattern, upper die and lower die and rotor silicon steel sheet lamination blank, the positioner by the collar that is loaded on taper key in the dummy shaft keyway and dummy shaft upper end is formed carries out centralized positioning up and down.The radial air discharge duct of some circumference uniform distributions that on the patrix upper surface, have an annular overlap overflow launder and connect with it; In upper and lower mould is joined on the seam up and down of mould, during promptly patrix lower surface and counterdie upper surface are joined on the mould seam, have an annular overlap overflow launder and the radial air discharge duct of some circumference uniform distributions connecting with it.Because air discharge duct is near from die cavity distance, and have a very wide distribution, quantity is many, therefore when the die casting apparatus for cast-aluminium rotor of electric machine, the gas that is produced in the die cavity can be discharged rapidly.

The beneficial effects of the utility model are: annular overlap overflow launder and air discharge duct be many apart from weak point, quantity from the die cavity exhaust, have a very wide distribution, has unobstructed quick, the good exhaust effect of exhaust, the remarkable advantage of being produced that rotor die casting pore is few, yield rate is high.
