The lower surface of the piston of described main ejection cylinder is provided with the sprue of through hole described in shutoff, and described sprue is provided with through-flow hole, described through-flow hole and described through hole UNICOM;
Described through-flow hole is connected with lower oil pipe, and the through hole above described piston is connected with upper oil pipe.
A kind of motor iron core rotor aluminum die casting, comprise cope match-plate pattern and lower bolster, also comprise vertical main ejection cylinder, upwards, a through hole is from the upper surface of the plane perpendicular of the piston of the described main ejection cylinder upwards through knock-pin to described main ejection cylinder for the knock-pin of described main ejection cylinder;
Be slidably equipped with time knock-pin in described through hole, described time knock-pin is provided with time piston, seals between described secondary piston and described through hole;
The lower surface of the piston of described main ejection cylinder is provided with the sprue of through hole described in shutoff, and described sprue is provided with through-flow hole, described through-flow hole and described through hole UNICOM;
Described through-flow hole is connected with lower oil pipe, and the through hole above described piston is connected with upper oil pipe;
The upper end of described knock-pin passes from the upper surface of the knock-pin of described main ejection cylinder, the top of described main ejection cylinder penetrates in described lower bolster, the upper surface of the knock-pin of cope match-plate pattern described after matched moulds, lower bolster, main ejection cylinder surrounds die cavity, and the upper end of described knock-pin is positioned at described die cavity.
Further, described knock-pin is also provided with ejects boss.
Further, described main ejection cylinder has six, is equipped with time knock-pin in each main ejection cylinder.
In use, product is shaping in die cavity in the present invention, shaping complete after, cope match-plate pattern die sinking, then main ejection cylinder action, product ejects by the knock-pin of main ejection cylinder.Afterwards by lower oil pipe oil-feed, secondary knock-pin ejects, further by shaping product roof fall.Main ejection cylinder resets afterwards, is resetted by after upper oil pipe oil-feed knock-pin.
Beneficial effect of the present invention is: by ejecting for twice of main ejection cylinder and time knock-pin, can eject the shaped article being also in high temperature safely, and it is high to eject efficiency.
