, The holes of the pins L of the iron fitting M remain in the male mold E, so that the iron fitting M cannot be repeatedly attached at the same position. Therefore, when it is necessary to attach and detach the male mold E and the iron fitting M many times, the mounting position of the iron fitting M must be changed each time. However, in this case, holes are formed on the surface of the male mold E in many places, and the male mold E is damaged. ． When the male mold E and the female mold F of the printing paper necessary for assembling a small paper box are made of wood, a small (not shown) protrusion is formed in the inner opening of the female mold F, and therefore dozens of sheets are left as they are. It is not possible to punch out the overlapping printing paper D. Therefore, in this case, the number of the printing papers D to be set is reduced, or a metal mold is used (manufacturing cost is higher than that of a wooden mold, and when a large amount of the same printing paper is punched out). Other than that, the profitability is not good), or a method of manually pulling out the product part B one by one must be taken. ． Since the exciting region of the electromagnet O of the lifting body G to which the iron fitting M is attached / detached is not divided into a plurality, the attraction force on the surface of the electromagnet O can be uneven, and even if the iron fitting M is attached at a desired position, that portion If the electromagnetic force of is weak, it may be attracted to the part with strong electromagnetic force and move. In this case, the mounting position of the male mold E is deviated, and the fitting with the female mold F becomes unsuccessful.
