Abstract
A clamp rod (20) is inserted into a through hole (2) of a base (1). The rod (20) is provided with a first external thread (21) adapted to engage with a clamping internal thread (11a) of a metal mold (11) and a second external thread (22) adapted to engage with a raising and lowering internal thread (12a). When the metal mold (11) is fixedly secured to the base (1), the rod (20) is rotated by an impact wrench (28). Thereupon, the rod (20) is screwed downward along the raising and lowering internal thread (12a) and then along the clamping internal thread (11a). Thereby, the base (1) is pressed downward by a pressing portion (23) of the rod (20).
