Complete motor rotor.Owing to being fixing Immobile type of attachment between existing cast-aluminum die and fixed plate, therefore make
Become mould release difficulty；It addition, existing die casting is in order to enable the smooth aerofluxus when die casting, the table plane at mould is needed to set
Put steam vent, owing to existing steam vent is multiple being independently arranged, arise that when one or more is blocked by aluminum liquid
Aerofluxus is not smooth, causes cast aluminium part surface the quality problems such as trachoma, pore occur, even makes aluminum liquid discharge and causes waste or hurt sb.'s feelings
Event.It is therefore desirable to prior art is improved.
Summary of the invention
For solving between existing cast-aluminum die and fixed plate because fixing Immobile type of attachment, easily cause mould
Dismounting difficulty, and steam vent is absolute construction, the most blocked arises that aerofluxus is smooth, and affects rotor quality, or
Causing the ejection of aluminum liquid and the problem such as hurt sb.'s feelings, this utility model provides another kind of motor rotor pressure-casting mold, in order to convenient dismounting,
Ensure smooth gas discharge, prevent aluminum liquid from spraying, improve rotor quality.
This utility model is completed by following technical proposal: a kind of motor rotor pressure-casting mold, including upper mold, middle mold and
Lower mold, upper mold end face is connected with the upper padding plate of forcing press, and lower mold is connected with the lower bolster of forcing press by gripper shoe, middle mold
Between upper and lower mould, and the central through hole of upper mold, middle mold and lower mold center is interconnected, and is provided with dummy shaft in central through hole,
Dummy shaft upper end connects has demoulding hanging bolt, lower end to be placed in lower mold, it is characterised in that gripper shoe is provided with annular groove, lower mold
Top be provided with the annular flange flange matched with this annular groove, bottom fixed plate with groove is placed in gripper shoe and lower mold,
Pressing plate is set in fixed plate, by pressing plate, the flexible connection of fixed plate, to facilitate the loading, unloading of lower mold and to fix.
Described fixed plate is by counter-sunk screw and gripper shoe bolt, thus lower mold is fixed on the annular groove of gripper shoe
In.
Described pressing plate is by counter-sunk screw and fixed plate bolt, in order to reinforcement fixed plate and gripper shoe, lower mold further
Between connection fix.
Described middle mold is made up of two half modules of longitudinally asymmetric separation, and sets respectively in the middle part of the upper and lower end end face of middle mold
Putting upper and lower boss, upper and lower boss is respectively placed in the annular groove that upper and lower mould is corresponding, in order to prevent spray outside cast aluminium liquid to hinder
People.
Described upper mold end face, lower mold bottom surface are provided with radial direction vertical bar groove and the annular of a plurality of distribution in lonizing radiation respectively
Groove, and radially vertical bar groove and annular groove intersect connection, in order to can pass through annular groove, radial direction when aerofluxus directly
The timely aerofluxus of bar groove, even if certain or a few radial direction vertical bar groove is blocked, also can be delivered to gas by annular groove
Other radially vertical bar groove discharges, it is to avoid gas is detained and is leaked by aluminum liquid.
This utility model has following advantages and effect: use such scheme, connects not only by pressing plate, the movable of fixed plate
Connecing, facilitate the loading, unloading of lower mold and fix, work efficiency is high, and the setting of the upper and lower concave station of middle mold, effectively prevent outside cast aluminium liquid
Spray and hurt sb.'s feelings, then by vertical bar groove on upper and lower mould and the setting of annular groove, it is possible to timely aerofluxus, though certain or certain
Several radial direction vertical bar groove is blocked, also by annular groove, gas can be delivered to other radial direction vertical bar grooves and discharge, it is to avoid gas
Body is detained and aluminum liquid leaks, and improves cast-aluminum rotor quality, reduces cost.An actually preferable mould of die casting machine.
