A punch mold with the adjusted punch-pins is provided to push punch-pins and a part of a die toward a depress unit so as to punch objects of different sizes. A punch mold with the adjusted punch-pins includes upper and lower molds(30,31). Punched holes are formed on surfaces of objects supplied between the upper and lower molds. The punch mold includes a plurality of punch-pins(33) provided to the upper mold, a plurality of dies provided to the lower mold to correspond to the punch-pins and to support the lower surfaces of the objects, and a slide member(50) provided to at least one of the upper and lower molds to slide and contact the punch-pins or the dies. The slide member has a depress unit(51). The punch-pin and the die corresponding to the depress unit are pushed toward the depress unit to avoid to contact the objects. The depress unit has a slope, surfaces of the punch-pin and the die corresponding to the depress unit have chambers, and the chambers keep in contacting the slope when the punch-pin and the die are pushed toward the depress unit. |
