PURPOSE:To shorten the period required when a molding surface reaches a prescribed temperature, by forming supply passages for a heating medium and a refrigerant independently adjacent to a molding space defined by a top force and a bottom force. CONSTITUTION:While a reinforcing material such as glass fiber is set on a molding surface 1a of a bottom force 1 that has been opened, a change-over valve 8 is changed over to flow a refrigerant from a cooling apparatus 14 to a supply passage 5 thereby cooling molding surfaces 2a, 1a. Thereafter, the change-over valves 8, 9 are changed over to allow a high pressure gas from a supply apparatus 12 to discharge the refrigerant remaining in the supply passage 5. Then the change-over valves 8, 9 are positioned in the neutral positions, and the change- over valve 6 is changed over to allow a heating medium from a heating apparatus 11 to flow into the molding surfaces 2a, 1a to heat then to a suitable temperature. Accordingly, the setting of a thermosetting synthetic resin filled in the molding space 3 can be facilitated in a short period of time. |
