Wherein, described balanced component is arranged near the position of described patrix punching pin.
Wherein, described lower bolster is also provided with the binder bullet part for supporting the movable binder part of described counterdie.
Wherein, described binder bullet part comprises the binder push rod supporting the movable binder part of described counterdie and the binder spring supporting described binder push rod.
Wherein, the bottom of described lower bolster is provided with lower bolster, die shoe successively, and described balancing pole and described binder push rod slide all successively and run through described lower bolster, described lower bolster, and described balancing spring and described binder spring are all built in described die shoe.
Wherein, described balancing pole and described binder push rod are equipped with the positive stop lug boss being held in described lower bolster.
Wherein, the top of described stripper plate is provided with de-backboard, train wheel bridge and upper padding plate successively, and described patrix punching pin is successively through described train wheel bridge, described de-backboard and described stripper plate.
The beneficial effect of the invention:
The bascule that the anti-mould punching pin of the invention fractures, by being provided with balanced component at lower bolster for balancing stripper plate, wherein, balanced component comprises the balancing spring of balancing pole and the balance support bar supporting stripper plate, and the height that balancing pole stretches out the plate face of lower bolster is equal with the height that the movable binder part of counterdie stretches out the plate face of lower bolster, this guarantees the balance of stripper plate, and then fractureing of patrix punching pin can be prevented, and the balance device structure of the invention is simple, low cost of manufacture, also any noise can not be produced when mould runs, economical and practical.
Accompanying drawing explanation
Accompanying drawing is utilized to be described further the invention, but the embodiment in accompanying drawing does not form any restriction to the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the following drawings.
Fig. 1 is the structural representation that in prior art, stripper plate tilts.
Fig. 2 is the structural representation of the bascule that a kind of anti-mould punching pin of the invention fractures.
Include in Fig. 1 and Fig. 2:
The movable binder part 4 of stripper plate 1, lower bolster 2, patrix punching pin 3, counterdie,
Binder bullet part 5, binder push rod 51, binder spring 52;
Balanced component 6, balancing pole 61, balancing spring 62;
Positive stop lug boss 7, lower bolster 8, die shoe 9, de-backboard 10, train wheel bridge 11, upper padding plate 12.
Detailed description of the invention
With the following Examples the invention is further described.
The detailed description of the invention of the bascule that a kind of anti-mould punching pin of the invention fractures as shown in Figure 2; comprise stripper plate 1 and lower bolster 2; described stripper plate 1 is provided with the patrix punching pin 3 running through described stripper plate 1; described lower bolster 2 left part is provided with the movable binder part 4 of the counterdie supporting described stripper plate 1; the right-hand member of described lower bolster 2 is provided with the balanced component 6 for balancing described stripper plate 1; for preventing stripper plate 1 from tilting further, described balanced component 6 is arranged near the position of described patrix punching pin 3.
Balanced component 6 comprises the balancing pole 61 supporting described stripper plate 1 and the balancing spring 62 supporting described balancing pole 61; the height that described balancing pole 61 stretches out the plate face of described lower bolster 2 is equal with the height that the movable binder part 4 of described counterdie stretches out the plate face of described lower bolster 2; this ensures that there the balance in stripper plate 1 horizontal direction; stripper plate 1 is avoided to tilt; and then fractureing of patrix punching pin 3 can be prevented; and the balance device structure of the invention is simple, low cost of manufacture; also any noise can not be produced when mould runs, economical and practical
When the demoulding, the movable binder part 4 of counterdie moves upward and supports stripper plate 1, is located at binder bullet part 5 below the movable binder part 4 of counterdie for supporting the movable binder part 4 of counterdie.
Further, binder bullet part 5 comprises the binder push rod 51 supporting the movable binder part 4 of counterdie and the binder spring 52 supporting binder push rod 51, the movable binder part 4 of counterdie can be moved downward when matched moulds, move upward when die sinking.
