8th, drive link 4 is fixed on upper die plate 2, promotes sliding pin 9 to move downward through holding pad 5 and lower template 6.
The present invention operationally includes following state and step：
First, mold state, as shown in Figure 2：
Tablet (workpiece 19) is placed in lower template 6, upper bolster 1 drive part of the upper die move upwards, holding pad 5 and install
Stop piece 3 in the above, holding pad unloading bolt 17 show state due to action of gravity to Fig. 2, and holding pad unloading bolt 17 is limited
It is not pressurized that position, binder spring 15 and dnockout spring 16 return to drift；
2nd, binder state, shown in Fig. 3：
Mold part is descending, starts to contact plate to holding pad 5, starts binder；
Now, dnockout pin 14 starts to contact punch 12, and drive link 4 starts to contact sliding pin 9, and binder spring 15 starts boil down to
5 binder of holding pad provides pressure-plate-force, and dnockout spring starts simultaneously at compression；
3rd, working condition, as shown in Figure 4：
As mold part is descending, drive link 4 promotes sliding pin 9 descending, and sliding pin 9 promotes rotary slider 10 to revolve around axle 11
Turn, rotary slider 10 promotes punch 12 up, mates with holding pad and completes hole flanging, punch 12 is up to promote 14 up pressure of dnockout pin
Contracting dnockout spring.
Mould state on earth：
Mould on earth after, sliding pin 9 goes downwards to bottom dead centre, the upper contact spacer pin 8 of the stopper slot 13 at sliding pin 9, rotation
Slide block 10 promotes punch 12 to arrive top dead-centre, and the lower contacts spacer pin 8 of the stopper slot 13 at punch 12 is allowed to transport upwards again
Dynamic, the blocking of dnockout pin 14 and 18 touches bottom.Upper hole flanging is completed, and mould is closed into bottom.
4th, mould backhaul, as shown in Figure 5：
During backhaul, upper mould is up, binder spring 15 and dnockout spring 16, discharge degree, and dnockout pin 14 is in dnockout spring 16
Promotion under descending, punch 12 is pushed down on the 13 upper contact spacer pin 8 of stopper slot at bottom dead centre, i.e. punch 12, convex
Mould 12 promotes 10 rotation forces sliding pin 9 of rotary slider up, so that the 13 lower contacts spacer pin 8 of stopper slot at sliding pin 9 makes
Can not move upwards again, in mold mechanism, all part reverts return to die sinking shape to initial condition as upper mould is up
State, a complete work process terminates.
The present invention can realize above-mentioned upper hole flanging process, and structure is compacter simple, and small volume solves prior art
The problem that in scheme, mould structure is complicated, mould development cost is high, precision is not high.
Its major advantage includes：
1st, adverse movement is realized by the mechanism, upper hole flanging；
2nd, sliding pin and slide roof friction TMD system structure ensure that precision, open stopper slot by side and limit stroke；
3rd, sliding pin and convex mold bottom are spherical, it is ensured that rotary slider rotates to any angle can no-float transmission
Power；
4th, rotary slider for semicircle, external arc and die shoe semicircle chute slide fit, it is ensured that precision；
5th, upper mould installs dnockout pin, promotes punch, rotary slider, sliding pin to reset by the reset of spring.
Should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments, it should be understood that non-limiting embodiment party
Case is illustrated as just example.The protection domain of the application essence to be required more is embodied in independent claims offer
Scope, and its dependent claims.
