Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
This utility model is a kind of lazy-tongs for ejector sleeve secondary top opening, wherein ejector sleeve secondary top opening bag
Including needle plate and lower needle plate under upper die and lower die, ejector sleeve, lazy-tongs are arranged between lower mold and lower needle plate and the two of lazy-tongs
End is connected with needle plate under ejector sleeve and lower needle plate respectively, and in the course of the work, lower needle plate can drive upper mold and department by lazy-tongs
The lower needle plate of cylinder moves jointly, and simultaneously when lazy-tongs move to predeterminated position, Synchronization Component makes ejector sleeve with the disengaging of lower needle plate
Lower needle plate transfixion, and make upper mold continuously move to preset height.
As shown in Figure 1 to Figure 3, these lazy-tongs include brace 100, drag hook 400 and slide block 200, the upper end of brace 100
Being fixed in lower mold, the lower end of brace 100 stretches on lower needle plate and lower needle plate can move along brace 100, the two ends of drag hook 400
Being connected with needle plate under ejector sleeve and lower needle plate respectively, slide block 200 is sheathed on brace 100 and one end of slide block 200 is inserted in drag hook
On 400, when slide block 200 is resisted against on drag hook 400, lower needle plate can drive drag hook 400 synchronizing moving and make under ejector sleeve needle plate to
On eject；When slide block 200 departs from drag hook 400, under ejector sleeve, the static and lower needle plate of needle plate can drive upper mold to continue up to eject,
Make upper mold and lower mold away from and facilitate the taking-up of profiled member.
Preferably, in the upper end of brace 100, to both sides, extension is formed with two installation portions 110, on two installation portions 110 respectively
Offer the installing hole running through installation portion 110 respectively, in installing hole, be provided with the installation screw for fixedly mounting portion 110,
The one end installing screw through installing hole and is threadedly connected in lower mold so that lower needle plate is lower needle plate during moving up
Can move along brace 100 and ensure brace 100 transfixion, it is ensured that the normal work that this use is novel, at brace 100
Lower end extends and is formed with connecting portion 120, and the outer surface at connecting portion 120 and brace 100 junction between the two offers the
One inclined-plane 121.
Further, above-mentioned slide block 200 is movably arranged on brace 100 and one end of slide block 200 is inserted in drag hook 400
On, slide block 200 offers second inclined-plane 210 corresponding with the first inclined-plane 121, in an initial condition, the second inclined-plane 210 supports
It is against on the first inclined-plane 121, due to the second inclined-plane 210 and phase interaction on the first inclined-plane 121 during slide block 200 moves up
Slide block 200 is firmly made to be moved rearwards by by brace 100 relatively so that slide block 200 departs from drag hook 400, it is ensured that this practicality is new
Type normally works.
Further, it is fixed with fixed plate 220 in the rear end of slide block 200, slide block 200 offers installing hole and in peace
Dress is provided with elastic component 230 in hole, and the two ends of elastic component 230 are connected with slide block 200 and fixed plate 220 respectively, in slide block 200 phase
During being relatively moved rearwards by brace 100, slide block 200 departs from drag hook 400 and above-mentioned elastic component 230 is compressed, instantly
When needle plate is reset to initial position, elastic component 230 can make slide block 200 again be inserted on drag hook 400, it is achieved that this utility model
Automatically reset, improve work efficiency of the present utility model.
Further, being equipped with connecting pin 500 on elastic component 230, one end of connecting pin 500 is through elastic component 230 also
Being inserted on slide block 200, the other end of connecting pin 500 is movably arranged in fixed plate 220, and above-mentioned slide block 200 can drive solid
Rationed marketing is moved and makes elastic component 230 compress, and the setting of connecting pin 500 avoids in use elastic component 230 and position occurs
Deviation and affect the generation of slide block 200 normal reset phenomenon, it is ensured that the present invention normally works.
Brace 100 is also arranged with cover plate 300 and cover plate 300 is positioned at above slide block 200, cover plate 300 is offered
Fixing groove is interior and fixed plate 220 is connected with cover plate 300 to have the fixing groove corresponding with slide block 200, above-mentioned slide block 200 to be arranged at,
The one end being provided with screw and screw on cover plate 300 through cover plate 300 and is threadedly connected on lower roof plate so that slide block 200 energy
Resting state is kept, it is ensured that this utility model normally works at vertical direction.
Drag hook 400, offers the stopper slot corresponding with slide block 200 on drag hook 400, and one end of described slide block 200 is arranged
In stopper slot, when slide block 200 is inserted in stopper slot, slide block 200 can move along brace 100 and make drag hook 400 along with
Slide block 200 synchronizing moving；When slide block 200 departs from stopper slot, drag hook 400 is static and described slide block 200 can continue along brace 100
Continuous mobile.
On the upper surface and lower surface of drag hook 400 side, inclined plane 600 is offered respectively at slide block 200, it is to avoid
During utility model works, occur that slide block 200 clamping stagnation affects this utility model in stopper slot and normally works phenomenon
Generation, improve work efficiency of the present utility model.
Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute
