It is connected to fourth link and the 5th connecting rod, fourth link and the 5th connecting rod are symmetrical, pass through between fourth link and the 5th connecting rod
Six-bar linkage is connected with each other, and fourth link passes through pin shaft with the 5th connecting rod respectively and connects second connecting rod and third connecting rod, and third connects
It being fixed on the rack at the top of bar by pin shaft, third connecting rod can be rotated around pin shaft, first connecting rod is connected at the top of second connecting rod, and
It being fixed on the rack by pin shaft, second connecting rod can be rotated around pin shaft, and angle is fixed between first connecting rod and second connecting rod, the
One connecting rod is driven by pin shaft connecting rod, the pull rod by eccentric structure.
Preferably, the eccentric structure includes a special-shaped block, special-shaped block connection cylinder piston rod is special-shaped to obtain power
Block center is a shaft, and the pull rod is connect with special-shaped block, and is connected to the edge of shaft.
Preferably, the eccentric stiffener includes the motor of eccentric wheel and driving eccentric wheel rotation, set on the eccentric wheel
There are multiple eccentric position fixed points, pull rod is connect with eccentric position fixed point one of on eccentric wheel as needed.
Preferably, a retention bead is equipped with, for preventing on the outer end of separate second connecting rod on the first connecting rod
Pull rod rotation is excessive.
The beneficial effect is that: when eccentric structure drives pull rod, pull rod, which can pull first connecting rod, makes its pushing, due to second
The top of connecting rod and third connecting rod is fixed on the rack, and is bent between second connecting rod and fourth link, and third connecting rod and the 5th connects
It is bent between bar, can thus die cutter be pulled to be lifted up along positioning pin, two o'clock acts on die cutter simultaneously, this original mold
Cutter is more uniformly stressed, and cutting is stablized, while reducing the loss to eccentric structure.
Detailed description of the invention
Examples of the present invention will be described by way of reference to the accompanying drawings, in which:
Fig. 1 is die cutter closing structure schematic diagram described in embodiment 1；
Fig. 2 is die cutter Unclosing structure schematic diagram described in embodiment 1；
Fig. 3 is die cutter closing structure schematic diagram described in embodiment 2；
Fig. 4 is die cutter Unclosing structure schematic diagram described in embodiment 2.
Specific embodiment

Embodiment 1
A kind of die-cutting apparatus as shown in Figure 1, including rack 1, lower plate 2 and die cutter 3 are uniformly arranged on lower plate 2 multiple
Positioning pin 13, die cutter 3 are set on positioning pin 13, are connected with fourth link 10 and by pin shaft above the die cutter 3
Five connecting rods 11, fourth link 10 and the 5th connecting rod 11 symmetrically, connect between fourth link 10 and the 5th connecting rod 11 by the 6th
Bar 12 is connected with each other, and fourth link 10 connects second connecting rod 8 and third connecting rod 9, third by pin shaft respectively with the 5th connecting rod 11
It is fixed in rack 1 at the top of connecting rod 9 by pin shaft, third connecting rod 9 can be rotated around pin shaft, connect first at the top of second connecting rod 8
Connecting rod 7, and being fixed in rack 1 by pin shaft, second connecting rod 8 can be rotated around pin shaft, first connecting rod 7 and second connecting rod 8 it
Between angle fix, by pin shaft connecting rod 6, the pull rod 6 is driven first connecting rod 7 by eccentric structure.
On outer end on the first connecting rod 7 far from second connecting rod 8, it is equipped with a retention bead, for preventing pull rod from turning 6
It is dynamic excessive.
The eccentric structure includes a special-shaped block 4, and special-shaped block 4 connects 5 piston rod of cylinder to obtain power, in special-shaped block 4
Centre is a shaft, and the pull rod 6 is connect with special-shaped block 4, and is connected to the edge of shaft.
When cylinder 5 pulls special-shaped block 4, as shown in Fig. 2, due to being eccentric structure between pull rod 6 and special-shaped block 4,
The pulling of cylinder 5 pushes pull rod 6, and between first connecting rod 7 and second connecting rod 8 angle be it is fixed, the pushing of pull rod 6 makes the
It bends between two connecting rods 8 and fourth link 10, is bent between third connecting rod 9 and the 5th connecting rod 11, due to second connecting rod 8 and third
Being fixed in rack 1 at the top of connecting rod 9 can not move, and the bending between connecting rod will be such that lower section die cutter 3 lifts along positioning pin 13
It rises, realizes the opening of die cutter 3, die cutter 3 is more uniformly stressed, and cylinder 5 can also subtract significantly under the action of connecting rod
