In order to design a formwork mould for producing concrete parts, comprising a formwork bottom and end and/or side formworks which are vertically movable with respect to this formwork bottom, in such a way as to avoid during the vertical raising of the end and side formworks from the freshly formed moulding that marginal parts of this not yet hardened moulding, remaining on the bottom formwork, stick to the end and side formworks and, owing to the shearing stress due to the upwardly moving formworks, are broken out from the moulding and that furthermore difficulties in raising the formworks also occur if there protrude from the flanks of the precast parts reinforcing ends, which are helpful for improving the bond of said parts with an in-situ concrete filling the intermediate spaces in the assembly made up of such parts, there are on the inside, facing the formwork interior, of at least some individual such end and/or side formworks formwork parts articulated by means of joint connections in such a way that, when raising the formworks, they perform at least one horizontal movement in the direction away from the formwork interior, coupled with their vertical movements.
