A moulding machine for bricks or the like, wherein moulding is accomplished by filling raw material for the bricks in a mould (1) and moulding the material between upper and lower plungers (2, 3) applied with pressure. A mould base (4) has aU-shaped configuration opened at its front side. The moulding machine is so assembled that when the mould (1) is raised, its cross section taken through a collar will not interfere with the cross section of the mould base (4), whereby the mold (1) and the upper and lower plungers (2, 3) are assembled. The assembly is free to telescope through the opening of the base (4). Thus, the moulding machine allows mould exchange to be effected more rapidly and more accurately than with the conventional moulding machine.
