Abstract:
A molding apparatus for obtaining a molded product by firmly fitting a molten thermoplastic resin onto a molding surface of a mold under a pressure lower than or equal to 100 kg/cm.sup.2 and curing, comprising:a mold main body;a mold body on which said molding surface is defined;supporting means for supporting said mold body relative to said mold main body with maintaining a space on the back side of said molding surface in a heat insulative manner, said supporting means including at least a heat insulative supporting member having a thermal conductivity of 0.001 to 1 Kcal/mh .degree.C. and a longitudinal elastic modulus of 0.01 to 10 kg/cm.sup.2 ;heating means for heating said molding surface from the back side thereof to a temperature higher than or equal to Vicat softening temperature (T) .degree.C. of said thermoplastic resin;cooling means for cooling said molding surface from the back side thereof to a temperature lower than or equal to (Vicat softening temperature (T) of the thermoplastic resin -10) .degree.C.;control means for controlling introduction and discharge of a fluid into and from said space, andpressure control means for controlling pressure of said fluid in said space corresponding to pressure to be exerted onto said molding surface.
