PURPOSE:To contrive the reduction of the molding time and the improvement of quality by interposing a wave guide for resin pre-heating in the halfway of a molded-resin supply guide. CONSTITUTION:The upper metal mold 4 is provided under the upper supporting frame 3 of the upper die 1 which can be split, and the lower metal 6 above the lower supporting frame 5 of the lower frame 2 in opposition thereto. Fused resin is guided via metal molds 4, 6 and gate part 10. Besides, the molded resin is supplied through a supply guide 12, and the wave guide 16 connected to a micro wave generating device 18 is interposed in the halfway of the guide. In this manner, the resin 11 is fast in reaching the condition of a fusing temperature because of pre-heating by means of microwaves, and accordingly the reduction of the molding time and high quality can be secured. |
