The invention provides a punching device capable of automatically picking and placing materials and used for a mould, and relates to the field of mould machining. The punching device capable of automatically picking and placing the materials and used for the mould comprises a base. A first telescopic rod is fixedly installed at the top of the base, a vertical rod is fixedly installed at the top of the first telescopic rod, and a sleeve is arranged at the top of the vertical rod in a sleeving mode. According to the punching device capable of automatically picking and placing the materials and used for the mould, through arrangement of the first telescopic rod, the vertical rod, the sleeve, a cross rod, a box body, a movable rod, a clamping plate, a motor, a screw rod, a sleeve pipe, a nut, a sliding chute, a sliding rod, a through hole, a supporting rod and a spring, the effect that the clamping plate at the bottom of the box body is convenient to move is achieved, so that the height of the clamping plate is further convenient to adjust, on this account, the effect that an object needing to be machined is convenient to move is achieved, accordingly, using of users is also convenient, the working efficiency of the punching device for the mould is also improved, and meanwhile the using efficiency of the punching device for the mould is further improved.
