This liftout mechanism 31 can leave the lower mould 3 after die-cut completion when the upper mould moves upwards, can upwards jack-up with the blade that breaks away from lower mould 3 (the up end in blanking hole forms the blade), the transport of the blank 4 of being convenient for. Preferably, the ejector mechanism 31 has elasticity, in other words, the ejector mechanism 31 can extend out of the top of the mounting hole when the upper and lower dies 3 are in a separated state, and can completely extend into the mounting hole when the upper and lower dies 3 are in a clamped state. Preferably, the mounting hole is a through hole. Further, the ejector mechanism 31 includes an ejector member 311, an elastic member 312, and a plug screw 313, the plug screw 313 is installed at the lower end of the installation hole to form a wall surface supporting the elastic member 312, the elastic member 312 is disposed above the plug screw 313, and the ejector member 311 is disposed above the elastic member 312. The screw plug 313 and the mounting hole can be in threaded connection, the elasticity of the elastic element 312 can be adjusted by adjusting the threaded connection amount, and the universality of the ejecting mechanism 31 is improved.

Specifically, as shown in fig. 3, the non-punching portion 41 of the blank 4 may further include a plurality of positioning holes 411, and the positioning holes 411 may correspond to two outermost mounting holes on the lower die 3 one by one. Further, as shown in fig. 2 and 4, the pressing mechanism 2 may further include a plurality of guide members 23 corresponding to the positioning holes 411 one to one. It should be noted that the guiding component 23 also extends out of the lower end surface of the second main body 21 like the pressing component 22, and the extending length of the guiding component 23 is larger than the extending length of the pressing component 22, so that when the upper die and the lower die 3 are closed, the guiding component 23 can first penetrate into the positioning hole 411 of the blank 4 and then penetrate into the mounting hole of the lower die 3 to perform preliminary guiding positioning on the blank 4, and then the pressing component 22 is pressed on the blank 4 to ensure that the position of the blank 4 can be accurate.
