Improvements in the mold of the concrete vibrating machines, which are characterized in that they are constructed in two pieces, preferably made of reinforced iron sheet with angled profiles and with U-shaped pieces for the centering of the internal one in relation to the external one in such a way that the space between the inversely inclined walls of one piece and another leave between them the space to be filled with the concrete and disposed at the ends of the lower side angle profile rotating handles intended to facilitate the demolding of the pieces once the mold is removed from the machine by 180º rotation of this one.
