In order to achieve the above objectives, the technical solution of the utility model is achieved in that
A kind of Double-ejection guide frame, including level-one ejecting mechanism, second level ejecting mechanism and guiding mechanism；
Level-one ejecting mechanism includes that level-one liftout plate, straight top connecting rod and level-one are directly pushed up, and the straight upper end for pushing up connecting rod and level-one are straight
Top is fixedly connected, and the straight lower end for pushing up connecting rod is fixedly connected with level-one liftout plate；
Second level ejecting mechanism includes second level liftout plate, oblique top connecting rod and second level oblique top, and the lower end of oblique top connecting rod passes through oblique top
Slide is arranged on second level liftout plate, and the upper end of oblique top connecting rod passes through after level-one is directly pushed up and is fixedly connected with second level oblique top；
Wedge block is fixedly installed in the setting of second level liftout plate on the upper surface of level-one liftout plate, level-one liftout plate, and wedge block is worn
Cross second level liftout plate；
Guiding mechanism is located at level-one and directly pushes up between second level liftout plate, guiding mechanism include the fixed support plate in position and
The first sliding shoe that can only be moved horizontally on the supporting plate is provided with falling of matching with wedge block upper end on the first sliding shoe
Angle.
Further, guiding mechanism further includes rear groove seat, and rear groove seat is fixed on die ontology, and pit seat is located at one
Between the straight top of grade and second level liftout plate, and straight top connecting rod and oblique top connecting rod both pass through rear groove seat, and support plate is fixed at pit
Seat is internal, is provided with the limit sliding chutes moved horizontally for the first sliding shoe, oblique top in rear groove seat and positioned at the top of support plate
Connecting rod passes through support plate and the first sliding shoe.
Further, slotted hole is provided in support plate along the direction of oblique top connecting rod floor projection, oblique top connecting rod passes through
The slotted hole of support plate.
Further, oblique-top sliding seat includes along the slideway that the direction of oblique top connecting rod floor projection is arranged and being located in slideway
The second sliding shoe, slideway is made of two front and back grooves disposed in parallel, and the lower end of the second sliding shoe and oblique top connecting rod is fixed
Connection.
Further, the position on second level liftout plate and above oblique-top sliding seat is provided with slotted hole, the side of slotted hole
To for along the setting of the direction of oblique top connecting rod floor projection.
Further, the lower end of the first sliding shoe and the upper end of wedge block are provided with inclined chamfering, and the two is mutual

The upper end of top connecting rod 5 passes through level-one and directly pushes up 3, and oblique top connecting rod 5 directly pushes up the displacement for not having horizontal direction in 3 in level-one, therefore
Level-one directly push up 3 move up during oblique top connecting rod 5 have displacement horizontally to the right), since wedge block 8 moves up, when
After having carried out primary ejection, the chamfering of wedge block 8 just cooperates with the chamfering of the first sliding shoe 10.
For traditional structure in Double-ejection, guiding distance is L1, sees Fig. 1.
For the utility model when carrying out Double-ejection, oil cylinder drives Double-ejection plate 4 to move up, at this moment due to wedge block
8 support the first sliding shoe 10 just, and support plate 9 has supporting role, 5 Double-ejection of oblique top connecting rod for the first sliding shoe 10
When stress point be oblique top connecting rod 5 and the first sliding shoe 10 contact point, the guiding distance of oblique top connecting rod 5 is shown in Fig. 6 for L2.L2 is led
To distance it is elongated compared with L1, the guiding distance of oblique top connecting rod 5 extends, and stress condition is greatly reduced, and solves guiding apart from mistake
It is short, the big bring fracture of 5 stress of oblique top connecting rod or stuck situation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
