The machine comprises an openable moulding box which has a perforated top side and is in the form of two separable semi-moulds. A sand blowing head is movably connected to the machine stand by at least one pair of parallel connecting elements which form a deformable parallelogram structure. The head is capable of being moved away from the perforated top side or against the latter for blowing a mixture of sand and binder into the interior of the mould.
