PURPOSE:To obtain a molded product in which a transfer takes place with a better surface precision, by a method wherein, after closing, resin is injected for filling through a slight opening of a cavity in a direction of a thickness, and cooling and curing all the way through a molded product to the center thereof, only a surface layer is fluidized by a rapid heating to add a compressing power. CONSTITUTION:A cooling/heating pipe for rapid cooling and rapid heating is embedded in a position allowing a cavity 25 and a movable core block 12 to be surrounded in a fixed core block 6 and a cavity 7. A mold, provided with heat insulating materials 5, 8 and 13 for isolating the fixed core block 6, the cavity block 7, and the movable core block 12 from other part, is used, and after closing, the cavity 25 is opened by a slight compression volume delta to fill the inside with the resin. After curing all the way through the resin to the center thereof, only the surface layer of the resin is fluidized by rapid re-heating, a surface precision is transferred through application of a compressing pressure, and the resin is then cooled and cured to remove a molded product. |
