In order to permit more effective cooling in comparison to the prior art, in particular in its floor area, of a hollow glass article (1) standing upright on the base (2) of a setting plate (4) provided with transcurrent orifices (9, 9′, 9″) forming a cavity (8) between a base (2) and the facing surface of the setting plate (4) of the standing surface (2″), it is proposed to utilize a part of the orifices (9) situated inside the standing surface (2″) for the supply of cooling air into the cavity (8), and to utilize the remaining orifices (9′) inside the standing surface (2″) only for the extraction of cooling air from the cavity (8). By configuring the orifices (9, 9′) that are utilized in each case for the supply and extraction of cooling air into and out of the cavity (8) so that they are at least approximately cross-sectionally identical, a throughput of cooling air through the cavity (8) and thus the available cooling performance can be varied within broad limits, but in the absence of an adverse effect on the stability of the hollow glass article (1) or a resulting risk of uncontrolled positional displacements on the setting plate (4).
Setting plate arrangement for a glass moulding machine comprising at least one setting plate (4) held horizontally in a machine frame for the setting down of at least one hollow glass article (1) intended for cooling and exhibiting a standing surface (2″) provided with orifices (9, 9′, 9″) intended for the passage of cooling air and a cooling air supply line (6), characterized in that a part of the orifices (9) situated inside the standing surface (2″) is arranged for the supply of cooling air and is in connection with the cooling air supply line (6), in that the part of the orifices (9′) remaining inside the standing surface (2″) is arranged for the extraction of cooling air, in that an all-over flow guide for the cooling air providing a transfer of heat with the base (2) of the hollow glass article (1) is arranged between the orifices (9, 9′), and in that the orifices (9, 9′) situated within the standing surface (2″) are arranged for the supply and extraction of cooling air with the intention that the largest possible throughput of cooling air can be achieved while retaining the stability of the hollow glass article (1) as it stands upright on the standing surface (2″) and limiting the development of a back pressure.
