PURPOSE:To eliminate a shortage in thickness of the confluence without providing a vent hole or splits of a mold especially, by providing a rectifying plate arriving at the vicinity of an insert by hanging down within a mold in splits of a foam molding tool. CONSTITUTION:Foaming raw materials poured within a mold space 6 is foamed after a pouring hole 14 is made to clog with a pouring plug 16 by making predetermined foaming raw materials cast through the pouring hole 4, under a state wherein an insert 10 and rectifying plate 20 are made to arrange within a form molding tool formed of a stationary mold 2 and movable mold 4. In this instance, even if filling speeds of a foaming and expanding foamable thing 22 are different on both sides of the insert 10 respectively from each other, the foamable thing 22 with which one side mold spatial part is filled is obstructed by a rectifying plate 20. Under the above state foaming and filling at the other side mold spatial part are advanced with the result that the foamable things 22 on both the sides of the same are run together at a rectifying plate 20 part. |
