くされることがあるという不都合を有している。However, in the case of the above-mentioned conventional structure, the use of a vacuum generator has a disadvantage in terms of economical efficiency due to the high equipment cost of the whole apparatus. Heating for curing has a structure that depends only on the heat from the heating mold.Therefore, since the heat curing time is long, shortening of the working time is strongly demanded. Since only one surface in contact with the mold is heated, distortion due to a difference in heat shrinkage is likely to occur inside the molded article, and the quality is inevitably deteriorated accordingly.
