All it is connected with pressing lever on two chutes, connects by pressing plate is fixing between two pressing levers, the end of described pressing plate
Portion is fixedly connected with by pressing spring, the described top being fixedly connected on pedestal by the bottom of pressing spring, the top of described pressing plate
Being fixedly connected with lower mold, the bottom of described top board is fixedly connected with hydraulic cylinder, and the bottom of described hydraulic cylinder is fixedly connected with even
Connecing block, the bottom of described contiguous block is fixedly connected with the mold suitable with lower mold, and the both sides of described contiguous block are the most fixing
Connecting and have connecting rod, bottom described connecting rod, the side away from contiguous block is fixedly connected with push rod.
Preferably, before and after described spacing shell inwall, both sides are fixedly connected with limited location block.
Preferably, bottom described pressing lever, the side away from pressing plate is fixedly connected with the first permanent magnet, described push rod
Bottom is fixedly connected with second permanent magnet suitable with the first permanent magnet.
Preferably, bottom described push rod, the horizontal plane at place is less than the horizontal plane at place, mold top.
Compared with prior art, the invention has the beneficial effects as follows: this electrical accessorie manufacture with automatic ejection function is used
Stamping machine, by pressing lever, pressing plate, matches by pressing spring and push rod, and push rod is by pressing pressing lever thus by pressing plate
Compressing downwards, pressing plate pressing makes pressing spring contraction by pressing spring, carries out punching press simultaneously, punching press complete after by by pressing spring
Resilience force the lower mold at pressing plate top is ejected, it is not necessary to manually lower mold being taken out, save manpower, work efficiency is more
Height, and avoid the potential safety hazard existing for manually lower mold being taken out, security performance is higher.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1-2, the present invention provides a kind of technical scheme: a kind of electrical accessorie manufacture with automatic ejection function
With stamping machine, including base plate 1 and top board 2, base plate 1 is connected by fixing post 3 is fixing with top board 2, and the top of base plate 1 is fixing to be connected
Having pedestal 4, the top of pedestal 4 to be fixedly connected with spacing shell 5, before and after spacing shell 5 inwall, both sides are fixedly connected with limited location block
15, limited block 15 is used for stopping pressing plate 7, prevents pressing plate 7 and lower mold 9 from ejecting from the opening part of spacing shell 5, spacing shell 5
Both sides all offer and on chute, and two chutes, be all connected with pressing lever 6, by pressing between two pressing levers 6
Plate 7 is fixing to be connected, and the bottom of pressing plate 7 is fixedly connected with by pressing spring 8, by pressing spring 8 for pressing plate 7 is ejected, thus
Lower mold 9 being ejected, it is not necessary to manual operation, time saving and energy saving, bottom pressing lever 6, the side away from pressing plate 7 is fixedly connected with
One permanent magnet 16, is fixedly connected on the top of pedestal 4 by the bottom of pressing spring 8, and the top of pressing plate 7 is fixedly connected with lower mold
9, the bottom of top board 2 is fixedly connected with hydraulic cylinder 10, hydraulic cylinder 10 for mold 12 is ejected, thus make mold 12 with under
Mould 9 matches and reaches the effect of punching press, and the bottom of hydraulic cylinder 10 is fixedly connected with contiguous block 11, and the bottom of contiguous block 11 is fixed
Connecting and have the mold 12 suitable with lower mold 9, the both sides of contiguous block 11 have been fixedly connected with connecting rod 13, connecting rod 13 end
Portion is fixedly connected with push rod 14 away from the side of contiguous block 11, and push rod 14 is used for pressing pressing lever 6 thus drives pressing plate 7 downward
Pressing pressing spring 8, the bottom of push rod 14 is fixedly connected with second permanent magnet 17 suitable with the first permanent magnet 16, and first forever
Produce suction when Magnet 16 mutually touches with the second permanent magnet 17, thus can drive when push rod 14 rises pressing lever 6 simultaneously
Rising, bottom push rod 14, the horizontal plane at place is less than the horizontal plane at place, mold 12 top, by pressing lever 6, pressing plate 7,
Matching by pressing spring 8 and push rod 14, pressing plate 7 by pressing pressing lever 6 thus is compressed downwards by push rod 14, and pressing plate 7 is pressed
Pressure make to shrink by pressing spring 8 by pressing spring 8, carry out punching press simultaneously, punching press complete after by by pressing spring 8 resilience force will pressing
The lower mold 9 at plate 7 top ejects, it is not necessary to manually lower mold 9 being taken out, save manpower, work efficiency is higher, and avoids
Manually lower mold 9 being taken out existing potential safety hazard, security performance is higher.
