(57) The invention relates to a mold (1) for a concrete voussoir, the mold comprising a curved bottom wall (11), surrounded by side walls (12; 13), and a mechanism (20) for pivoting at least one side wall (12) from a first folded/closed position to a second inclined/open position, and vice versa. The pivoting mechanism (20) comprises: a support (2) secured to the mold (1); an elongate member (26) connected to the articulated side wall via a connecting member (28, 29a, 29b) and having an external thread; a rocker (24) connected in an articulated manner to the support (2) at a first pivot (25); an actuating cylinder (21) fixed to the support (2) and comprising a linearly movable rod (22) connected in an articulated manner to the rocker (24) at a second pivot (23) thereof; and a first threaded nut (27) engaged with the external thread of the elongate member (26) and connected in an articulated manner to the rocker (24).
