A mold accommodating device (1) is disposed on a side of a press brake (3). Within the mold accommodating device (1), lower mold holders (105) are raised up from lower mold holder support members (33L, 33R) and moved to the forward side or the rearward side, and both end sides in the left and right direction of the lower mold holders (105) are lowered so as to pass through recessed parts (117) formed on the lower mold holder support members (33L, 33R) (Step (a)). The lower mold holders (105) that have been lowered are transported forward and positioned at the same height as a lower mold attaching unit (11) on a lower table (13) (Step (b)). Lower molds (103) held by the lower mold holders (105) are transferred to the lower mold attaching unit (11) by a mold replacement device (19L) and attached to the lower table (13) (Step (c)). Step (c), Step (b), and Step (a) are carried out in reverse order, and the lower molds (103) attached to the lower table (13) are returned to the inside of the mold accommodating device (1) (Step (d)). |
