| description | PURPOSE:To obtain a molded article of good quality and to improve productivity by shortening a molding cycle, by providing a heating device on the surface facing on a molding space or close to the surface. CONSTITUTION:A cavity 6 contains an insulating layer 8 to be formed extending over the whole area of the surface of a cavity 7 of a mold 2 and a conducting film 9 of a heating device. As for the insulating layer 8, ceramics is suitable for the same and as for the conducting film 9, for example, copper foil is adopted. As for the conducting film 9, heating and deheating are fulfilled by making application and release of predetermined voltage to and from a control circuit 10. A molded article of good quality can be obtained as balance in molding shrinkage is kept maintained on a thermoplastic material 11 by setting only the surface temperature of a cavity 6 high while setting the temperatures of the molds 2, 3 low, and shortening of a molding cycle can be contrived by ascending and descending the surface temperature of the cavity 6 instantaneously. |
