Date Jul. 26, 1990.Lower structure of a mould for the pressure casting of flat products such as slabs and method for mount and removing the lower spacer of this mould is provided. The lower structure of the mould includes an intermediate beam (26) resting freely on a frame (3) whose upper surface opposite to its surface bearing on the frame (3) carries a lower spacer (4) which is fixed by clips (37) on the beam (26). At least one positioning pin (54) is engaged in a housing (55) at the front part of the frame (3). A plurality of members (47) for holding the intermediate beam (26) on the frame are distributed according to the length of the beam (26). These members each comprise a part (46) which can be engaged longitudinally in a coupling device (45) attached to the beam (26) and which can be actuated in order to hold the beam (26) on the frame (3) or, on the other hand, in order to release it. The device also includes a members for displacing the intermediate beam (26) relative to the frame (3) in a longitudinal direction over a distance which is sufficient to engage or release the pin (54) with or from housing (55) and the engagement parts (46) of the holding means (47) with or from the corresponding coupling devices (45).
