気工事用材料等の分野で注目されている。2. Description of the Related Art Synthetic resins have been used in various fields in place of conventional materials such as metals or cements because of their characteristics such as lightness and strength. Because of its excellent heat resistance and flame retardancy, it has attracted attention in the field of electrical construction materials and the like.

る。[0003] However, the molding of phenolic resin moldings is
A method is used in which a phenol resin mixed with an appropriate amount of a curing agent is injected into a mold and heated and molded.However, during the curing of the phenol resin, a considerable amount of water and steam moisture and volatile components are generated from the phenol resin. As a result, irregularities called "avatars" are formed on the surface of the molded article after curing due to the moisture and the like, thereby deteriorating the aesthetic appearance and remaining as water remaining inside the molded article, resulting in a deterioration in quality.
【0004】このため、従来では、形成途中において型
枠を少し開く工程、いわゆるガス抜き工程を適数回行
い、発生する水分等の除去を行っていた。[0004] For this reason, conventionally, a step of slightly opening the mold during the formation, a so-called degassing step, is performed an appropriate number of times to remove generated moisture and the like.

いた。Since the degassing step is performed an appropriate number of times as described above, the degassing step requires time,
In particular, when molding a long molded product or a molded product having a complicated shape having a large thickness, there is a problem that the time and labor required for the degassing step are increased and the production efficiency is significantly reduced. In addition, in the above-described degassing process, the dimensions of the molded product are likely to be out of order due to the swelling phenomenon associated with the disassembly / assembly and sliding / returning of the mold, resulting in a decrease in the dimensional accuracy of the molded product. Further, when a desired strength is required, a reinforcing bar or the like is disposed inside the molded product, but there has been a problem such as an increase in weight.
