Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, the anti-jamming die comprises an upper die 1 and a lower die 2, wherein the upper die 1 is provided with a punching hole 11;

the lower die 2 is provided with a knife line 211, the knife line 211 is matched with the punching hole 11, the shape of the knife line 211 is matched with the shape of the preset punching, the knife line 211 can be circular, oval, quadrilateral, polygonal or other shapes, and the knife line 211 is of a hollow structure;

the lower die 2 is further provided with a thimble 221, and the thimble 221 is movably inserted in the knife line 211;

after the cutting line 211 completes the punching operation, the thimble 221 can move upward and be higher than the cutting line 211 by a little than the cutting line 211.

After the adhesive tape and the like are punched by the knife line 211, the ejector pin 221 moves upwards and moves to the ejector pin 221 to be higher than the knife line 211, so that excess materials, waste materials and the like adhered to the knife line 211 or the adhesive tape clamped on the knife line 211 can be ejected away from the knife line 211, knife breakage is reduced or prevented, punching precision is improved, the knife line 211 is protected, deformation and damage of a die are reduced, and particularly, the situations of knife breakage, die deformation and the like can be effectively reduced or prevented for small-size punching dies.

Further, when the knife line 211 is punched, the thimble 221 can move downward; after the cutting wire 211 completes the punching operation, the thimble 221 can move upward.

To explain further, the thimble 221 moves upward by the power provided by the spring 23. The spring 23 urges the thimble 221 to move upward.

Further, the lower mold 2 further includes a height adjusting block 222, and the upper mold 1 and the lower mold 2 can push the height adjusting block 222 when closing the molds, so as to drive the thimble 221 to move downward. For example, when the mold is closed, the upper mold 1 moves downward and pushes the height adjusting block 222 to move downward, thereby moving the thimble 221 downward.
