Embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes.
Fig. 2 to Fig. 8, one kind delay bidirectional knockout core sliding block, including slider body 4, base 5, oil cylinder 1 and oil cylinder is referred to consolidate
Reservation 3, further includes oblique core-pulling device 6 and flexible limit buckle 8；The base 5 is connected fixation, the slider body with mode bottom plate
4 are fixed on the base 5；The oil cylinder 1 is connected fixation with the oil cylinder fixing base 3, and the oil cylinder fixing base 3 passes through screw
It is fixed on the side of the mode bottom plate.The oil cylinder 1 is equipped with pull rod 2 and the pull rod 2 is embedded in the slider body 4 one
Side；Inclined guide groove is equipped with the slider body 4；The base 5 is equipped with fixed block 7, and the fixed block 7 passes through screw and mode bottom
Plate connection is fixed；The fixed block 7 is embedded with the flexible limit buckle 8, and the top side of the flexible limit buckle 8 is inclined-plane
801 and middle it is equipped with boss 802.
The tiltedly core-pulling device 6 be embedded in the slider body 4, and the tiltedly core-pulling device 6 includes oblique Loose core block 601, oblique
Core pulling fixed block 602 and two delay stroke briquettings 604, the tiltedly core pulling fixed block 602, which is equipped with card slot and the card slot, to be set
There is guide finger 603,602 bottom of the tiltedly core pulling fixed block is equipped with chuck 605 and flexible 8 boss of limit buckle, the 802 corresponding contract
Close；Tiltedly 601 side of Loose core block is forming surface, and the bottom of the tiltedly 601 forming surface side of Loose core block is equipped with return chuck
606；The tiltedly 601 forming surface side of core-pulling slide block through the inclined guide groove in the slider body 4 and with the slider body
Forming surface is bonded, and tiltedly 601 opposite side of Loose core block is movable even by the guide finger 603 and the tiltedly core pulling fixed block 602
Connect；The delay stroke briquetting 604 is embedded in the slider body 4 and is respectively provided at the both sides of the tiltedly core pulling fixed block 602, institute
State 604 bottom of delay stroke briquetting and be equipped with inclined thrust surface fitting corresponding with the inclined-plane of the flexible limit buckle 8.
The bottom of the flexible limit buckle 8 is equipped with spring groove, and multiple compression springs 9 are equipped with the spring groove.It is described to stretch
