Abstract

PURPOSE:To make it possible to process molding ceiling or the like with low odor and low material cost by a structure wherein at least the part, which forms the forming surface, of a mold main body is made of porous member. CONSTITUTION:After a bottom force 10 and a top force 20 are heated with a heater, resin felt 30 is clamped between the bottom force 10 and the top force 20. In this case, odorous gas such as amine gas, ammonium gas or the like develops from the thermosetting resin in the resin felt 20. The odorousgas mostly expands by the heat given from both the bottom force 10 and the top force 20, passes through the passages in porous members 12 and 22 and exhausts from the sides of the forces and venting holes 13 and 23. Further, since said exhausting action is performed at the part of a projected part 21a, a large number of projections 22b are provided so as to increase the surface area of a mold surface 22c in order to effectively perform the exhaustion of odorous generated gas. At the manufacture of the molding ceiling of automobile or the like, the processing of the molding ceiling or the like with low odor development and low material cost can be performed.
