| Summary: | a b a b a b a ba b a b A press molding apparatus includes upper and lower mother molds and . Each of the mother molds and has four molding surfaces arranged in a single line and satisfies the relationship given by L×α×ΔT/t<0.0008, where L represents the length, t, the thickness, α, the thermal expansion coefficient, and ΔT, the temperature difference between both ends in the thickness direction during induction heating. The press molding apparatus may include a pressing mold set including upper mother molds and attached to a common fixed shaft through upper supporting shafts and and lower mother molds and driven by a common drive shaft through lower supporting shafts and . The upper mother molds and and the lower mother molds and are collectively heated by induction heating coils and , respectively. |
