PURPOSE:To obtain the titled mold wherein uneven distribution of high-frequency energy is lessened, by making a part of mold outer surface member which will be in contact with a part of less high-frequency loss with a low dielectric loss, and supplying high-frequency energy through this dielectric. CONSTITUTION:The insides of side sections 5, 6 of a foaming mold and an upper section 7 having an injection head 12 in communication with foamable resin feeding tanks 9, 10 are provided with a box space 3 comprising a metallic outer box 1 and a thin synthetic resin inner box 2, and an inner mold 18 made of a material having a low dielectric loss is arranged in contact with the inner box 2. Metallic rotating vanes 21 for scattering high-frequency energy to be fed to the foamable resin in the space 3 are provided within an inner space 19 made up of the inner mold 18 and a bottom 4 having a waveguide 20 in communication with a high-frequency energy generating apparatus 14. |
