Device for supporting and regulating the position of an upper spacer of a mould for pressure casting flat metal products

Device for supporting and regulating the position of an upper spacer of a mould for pressure casting a flat metal product, carried by a frame, said mould including two parallel lateral walls, each formed by a support equipped on the inside with a graphite block, a longitudinal lower spacer inserted between the graphite blocks at the base of the latter, a front spacer, the lower end of which delimits, with the adjacent end of the lower spacer, an orifice for molten metal to enter inside the mould between the graphite blocks of the lateral walls and the spacers, a rear spacer inserted between the upper and lower spacers and having a height corresponding to the width of the flat product, the upper spacer being inserted between the graphite blocks along their upper edges, the lateral walls being associated with means for the transverse displacement of the lateral walls and for clamping them against the spacers in order to form a cavity from which molten metal cannot leak, and the lateral walls also being connected to rigid longitudinal beams parallel to the said lateral walls, carried by the frame and displaceable transversely relative to the latter by the said means,

• said device comprising means supporting said upper spacer and for providing free pendular suspension of the upper spacer in the horizontal direction, said device being mounted on one of the longitudinal beams.
