PURPOSE:To discharge residual cooling water completely by a method wherein the foaming molding is cooled, a forming die is opened slightly, compressed air is supplied between the core die and the foaming molding and compressed air is fed between a cavity die and the foaming molding. CONSTITUTION:The foaming molding 7 is formed in a die cavity 4 between the core die 2 and the caviy die 3, and cooling water is introduced into steam chambers 23, 33 from cooling water pipes 26, 36 to cool the foaming molding 7. Air valves 29, 39 are opened, and the cooling water in the steam chambers 23, 33 is discharged forcedly. The forming die 1 is opened slightly, compressed air is supplied from a pressure air pipe 27 mounted to an inside wall 21 of the core die, the forming die is clamped once, and slightly opened again, compressed air is fed from a pressure air pipe 37 set up to an inside wall 31 of the cavity die, and cooling water remaining in steam holes 24, 34 is discharged. The forming die is clamped again, and left as it is cooled naturally. |
