The course of work of ejecting mechanism is as follows:
The oil cylinder 500 starts, and the upper needle plate 103 and the lower needle plate 102 is driven to move up and down, the position-limited needle
Plate 101 moves up and down under the action of the mechanical drag hook being mechanically connected with the oil cylinder 500 with the upper and lower needle plate movement.Institute
State limit needle plate 101 upwards ejection 30mm when, the cover half of first limited post 204 and automobile die contacts and prevents the limit
Position needle plate 101 moves further up.During the limit needle plate 101 moves upwards 30mm, the limit needle plate 101
The power rail 104 is also driven to move upwards simultaneously, then the jacking block 203 on the power rail 104 is with the power rail 104
Also 30mm is moved upwards, at this time under the transmitting effect of power, the jacking block 203 of the horn cover of automobile door plate in the power rail 104
Promotion under be also ejected 30mm upwards, the horn cover break away from moulds of automobile door plate 300 at this time.
The oil cylinder 500 works on, and the upper needle plate 103 and the lower needle plate 102 are under the drive of the oil cylinder 500
It continues up, at this point, the jacking block 203 also moves upwards simultaneously with the upper needle plate 103, and outer with automobile door plate
EDGE CONTACT.In the upper needle plate 103 and the lower needle plate 102 continue up, the jacking block 203 also heads on the vapour
Door panel moves upwards.When the cover half of second limited post 205 and the automobile door plate mold contacts and prevents the upper needle
When plate 103 is further mobile, the upper needle plate 103 described at this time has moved up 180mm, while the jacking block 205 will also head on institute
The outer edge for stating automobile door plate has moved up 180mm, i.e., automobile door plate break away from moulds 180mm at this time.Worker removes car door
Panel products complete whole procedure.
It should be understood by those skilled in the art that foregoing description and the embodiment of the present invention shown in the drawings are only used as illustrating
And it is not intended to limit the present invention.The purpose of the present invention has been fully and effectively achieved.Function and structural principle of the invention exists
It shows and illustrates in embodiment, under without departing from the principle, embodiments of the present invention can have any deformation or modification.
