Abstract

PURPOSE:To mass-produce formed product having air breathing porosity by establishing backward and forward-movable rod on the forming surface of metal mold and causing beads to be foamed with vapor introduced through movable rod after clamping the molds in such state that the said rod is fitted on the forming surface of the other metal mold. CONSTITUTION:Backward and forward-movable rod 4 whose back end is fixed on the piston-action plate 41 is established on the required position of metal mold 1's forming surface. After the metal molds 1, 2 are fastened and the tip of rod 4 is placed in such state that it is thrusted on the forming surface of metal form 2, raw material beads A' are introduced into the cavity 3 by way of pipe 24. Following this process, vapor is conducted into air 11 through pipe 13 and is blown into the cavity 3 through rod 4's vent 43, causing beads A' to be foamed. Thus PSB foam- formed body 4 is obtained. After that, residual vapor is discharged from pipe 14 and cooling water is introduced into the vacant chambers 11, 21 to be followed by mold- opening after cooling.
