Abstract

The utility model relates to a pressure casting mould for motor cast-aluminum rotor casting. The pressure casting mould comprises an upper supporting plate, an upper pressure casting mould and a lower pressure casting mould, a circular air discharge groove is formed in the upper pressure casting mould and is 30-40mm away from a cavity used for casting cooling blades in the upper pressure casting mould, and 8-10 rectangular air discharge grooves are arranged in the plane where the upper pressure casting mould is contacted with the upper supporting plate. The circular air discharge groove is 10+/-0.5mm in depth, 8+/-0.5mm in width. Each rectangular air discharge groove is 20+/-0.5mm in depth and 0.5+/-0.05mm in depth. The upper pressure casting mould is connected with the upper supporting plate through bolts. Cavity shrinking and cracking generated from products in casting can be effectively prevented. A cast-aluminum rotor cast in the pressure casting mould is high in quality.

Description

Apparatus for cast-aluminium rotor of electric machine casting compression mod
Technical field
The utility model relates to a kind of apparatus for cast-aluminium rotor of electric machine casting compression mod.
Background technology
The die casting module system that motor rotor pressure cast aluminium is used is using rotor core as an inserts, and its flute profile is a major part that forms die cavity, plays the channeling between upper and lower mould.Being formed by mounting plate (being connected rebound) between die casting patrix and die casting machine, die casting patrix, middle cover, dummy shaft, primary and secondary key, die casting counterdie of rotor die casting mold.In end face when casting of entering aluminium mode and adopt fan blade and balance columns of die-casting die for aluminum cast rotor of motor, because the time of aluminum liquid filling type in press casting procedure is short,, air can not effectively be discharged in the chamber in, and when casting, product produces easily generation shrinkage cavity and seminess.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of apparatus for cast-aluminium rotor of electric machine casting compression mod is provided, while preventing from casting, product produces shrinkage cavity and seminess.
The utility model solves the technical scheme that its technical problem adopts: a kind of apparatus for cast-aluminium rotor of electric machine casting compression mod, there is mounting plate, die casting patrix, die casting counterdie, on described die casting patrix, offer annulus air discharge duct, described annulus air discharge duct apart from die casting patrix for casting the die cavity 30~40mm of radiator shutter, the plane that described die casting patrix contacts with mounting plate is offered multiple rectangle air discharge ducts.
Further, the degree of depth of described annulus air discharge duct is 10 ± 0.5mm, and ring width is 8 ± 0.5mm.
Further, the quantity of described rectangle air discharge duct is 8~10, and the width of described rectangle air discharge duct is 20 ± 0.5mm, and the degree of depth of described rectangle air discharge duct is 0.5 ± 0.05mm.
The joint face of described die casting patrix and mounting plate has flange, in described flange, offers bolt connecting hole, and described die casting patrix and mounting plate are bolted,
The beneficial effects of the utility model are: the utility model is by increasing annulus air discharge duct and multiple rectangle air discharge duct, can discharge fast and effectively for the air of casting in the die cavity of radiator shutter, and while effectively preventing from casting, product produces shrinkage cavity and seminess.The joint face of die casting patrix and mounting plate has flange, offers bolt connecting hole in flange, and die casting patrix and mounting plate are bolted.Mounting plate and die casting patrix can easily be thrown off like this.The apparatus for cast-aluminium rotor of electric machine quality that adopts apparatus for cast-aluminium rotor of electric machine of the present utility model to cast to be cast into compression mod is higher.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of die casting patrix in the utility model;
Fig. 2 is that the A of Fig. 1 is to schematic diagram;
Wherein: 1, die casting patrix, 11, annulus air discharge duct, 12, rectangle air discharge duct, 13, flange.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Fig. 1 Fig. 2, a kind of apparatus for cast-aluminium rotor of electric machine casting compression mod, there is mounting plate, die casting patrix 1, die casting counterdie, on die casting patrix 1, offer annulus air discharge duct 11, annulus air discharge duct 11 apart from die casting patrix 1 for casting the die cavity 30~40mm of radiator shutter, preferably the degree of depth of annulus air discharge duct 11 is 10 ± 0.5mm, and ring width is 8 ± 0.5mm.
The plane that die casting patrix 1 contacts with mounting plate is offered multiple rectangle air discharge ducts 12.Preferably the quantity of rectangle air discharge duct 12 is 8~10, and preferably the width of rectangle air discharge duct 12 is 20 ± 0.5mm, and the degree of depth of rectangle air discharge duct 12 is 0.5 ± 0.05mm.
Die casting patrix 1 has flange 13 with the joint face of mounting plate, in flange 13, offers bolt connecting hole, and die casting patrix and mounting plate are bolted.
The end face casting that aluminium mode is fan blade and balance columns of entering of compression mod for the apparatus for cast-aluminium rotor of electric machine casting that the present embodiment adopts.Because the time of aluminum liquid filling type in press casting procedure is short, must offer enough air discharge ducts, air in chamber is regularly discharged as early as possible, while preventing from casting, produce shrinkage cavity and seminess.
The utility model is by increasing annulus air discharge duct 11 and multiple rectangle air discharge duct 12, can discharge fast and effectively for the air of casting in the die cavity of radiator shutter, and while effectively preventing from casting, product produces shrinkage cavity and seminess.The joint face of die casting patrix and mounting plate has flange, offers bolt connecting hole in flange, and die casting patrix and mounting plate are bolted.Mounting plate and die casting patrix can easily be thrown off like this.The apparatus for cast-aluminium rotor of electric machine quality that adopts apparatus for cast-aluminium rotor of electric machine of the present utility model to cast to be cast into compression mod is higher.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
