1. A system for cracking at least one flexible mold of dried wet-cast concrete products, the system comprising:
a table defining a surface for receiving the at least one flexible mold thereon; the table including at least one opening;
at least one mold-bending member mounted to the table so as to be movable in and out of the at least one opening, respectively towards and away a mold-contacting position that forces an edge portion of the at least one flexible mold to move away from the surface; the at least one mold-bending member being mounted to the table under the surface thereof via a mounting member that includes i) a first arm that is pivotably mounted to the table, and ii) a second arm that receives the at least one mold-bending member;
at least one mold-support member mounted to the table so as to be movable towards and away the table adjacent the at least one opening to prevent a portion of the at least one flexible mold that is adjacent the edge portion to move in a same direction than the edge portion when the at least one mold bending member is in the mold-contacting position and the at least one-mold support member is moved towards the table, adjacent the at least one opening; and
an actuating mechanism, mounted to both the mounting member and to the at least one mold-support member, that is movable to cause the at least one mold-bending member to pivot towards and away the mold-contacting position simultaneously to moving the at least one mold-support member respectively towards and away the surface of the table.
