Die ejection system and adopt the motor iron core rotor aluminum die casting of this ejection system
(1) technical field
The present invention relates to die ejection system and motor iron core rotor aluminum die casting.
(2) background technology
NEO motor iron core rotor is as the indispensable part on family's electric notors such as air-conditioning (indoor set, off-premises station), motor's for washing machine, especially be applied at present as on the new ideas DC brushless motor of low energy consumption, environmental protection, its importance is well imagined.Because new ideas DC brushless motor market prospects are very wide, lot of domestic and international producer is all in development, but plastic packaging motor is still in the starting stage at home, to the design of this type of mould, to manufacture also be all traditional approach, especially ejecting mechanism or traditional thimble, be not suitable with ejecting of motor iron core rotor.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing motor iron core rotor aluminum die casting, the invention provides a kind of die ejection system and adopting the motor iron core rotor aluminum die casting of this ejection system.
The technical scheme that the present invention solves its technical problem is: die ejection system, 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 upper end of described knock-pin passes from the upper surface of the knock-pin of described main ejection cylinder;
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.

(5) detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
With reference to Fig. 1, Fig. 2, die ejection system, comprise vertical main ejection cylinder 1, upwards, a through hole is from the upper surface of the plane perpendicular of the piston of the described main ejection cylinder 1 upwards through knock-pin 2 to described main ejection cylinder for the knock-pin 2 of described main ejection cylinder.
Be slidably equipped with time knock-pin 3 in described through hole, described time knock-pin 3 is provided with time piston 4, seals between described secondary piston 4 and described through hole; The upper end of described knock-pin 3 passes from the upper surface of the knock-pin 2 of described main ejection cylinder.
The lower surface of the piston of described main ejection cylinder 1 is provided with the sprue 5 of through hole described in shutoff, and described sprue 5 is provided with through-flow hole 6, described through-flow hole 6 and described through hole UNICOM.
Described through-flow hole 6 is connected with lower oil pipe, and the through hole above described piston 4 is connected with upper oil pipe.
A kind of motor iron core rotor aluminum die casting adopting above-mentioned ejection system, comprise cope match-plate pattern 7 and lower bolster 8, also comprise vertical main ejection cylinder 1, upwards, a through hole is from the upper surface of the plane perpendicular of the piston of the described main ejection cylinder 1 upwards through knock-pin 2 to described main ejection cylinder for the knock-pin 2 of described main ejection cylinder.
Be slidably equipped with time knock-pin 3 in described through hole, described time knock-pin 3 is provided with time piston 4, seals between described secondary piston 4 and described through hole.
The lower surface of the piston of described main ejection cylinder 1 is provided with the sprue 5 of through hole described in shutoff, and described sprue 5 is provided with through-flow hole 6, described through-flow hole 6 and described through hole UNICOM.
Described through-flow hole 6 is connected with lower oil pipe, and the through hole above described piston 4 is connected with upper oil pipe.
The upper end of described knock-pin 3 passes from the upper surface of the knock-pin 2 of described main ejection cylinder, the top of described main ejection cylinder 1 penetrates in described lower bolster 8, the upper surface of the knock-pin 2 of cope match-plate pattern 7 described after matched moulds, lower bolster 8, main ejection cylinder surrounds die cavity, and the upper end of described knock-pin 3 is positioned at described die cavity.
In the present embodiment, described main ejection cylinder has six, is equipped with time knock-pin in each main ejection cylinder, can one-shot forming six products.
In use, product is shaping in die cavity, shaping complete after, cope match-plate pattern 7 die sinking, then main ejection cylinder 1 action, product ejects by the knock-pin 2 of main ejection cylinder.Afterwards by lower oil pipe oil-feed, secondary knock-pin 3 ejects, and further by shaping product roof fall, in the present embodiment, described knock-pin 3 is also provided with and ejects boss, be convenient to product roof fall further.Main ejection cylinder 1 resets afterwards, is resetted by after upper oil pipe oil-feed knock-pin 3.
