隙間をあけている。[Prior art] Conventionally, when forming a foam panel, two plate materials are usually combined, inserted into a mold, and filled with a foam material into an inner cavity of the two plate materials to form a foam. The whole is united. In such a manufacturing method, a gap is provided in a joint portion between two plate members in order to completely fill the foam material.
［発明が解決しようとする課題］ 前記従来の製法では板材の隙間からはみ出した材料が
バリのように残り、それを削る作業がやっかいであると
いう問題がある。[Problem to be Solved by the Invention] In the above-mentioned conventional manufacturing method, there is a problem that the material protruding from the gap of the plate material remains like burrs, and the work of cutting the material is troublesome.
またはみ出る材料が広がらないように金型との隙間を
シールしておく必要があり、成形前の準備作業がきわめ
て煩雑である。In addition, it is necessary to seal the gap between the mold and the material so that the protruding material does not spread, and the preparation work before molding is extremely complicated.
前記はみ出てくるバリを少なくするため、たとえば前

ると共に、板材の適切な位置にガス抜き孔を設けておく
ことが考えらえる。In order to reduce the protruding burrs, for example, it is conceivable that peripheral edges of the two plate members are airtightly fitted in advance and gas vent holes are provided at appropriate positions on the plate members.
しかしガス抜き孔を大きくするとはみ出る発泡材料の
後処理が面倒であり、小さ過ぎると孔が詰ったり、充分
なガス抜きを行なうことができないという問題がある。
またそのばあいでも板材と金型間のシート作業は必要で
ある。However, if the gas vent hole is enlarged, post-processing of the protruding foam material is troublesome, and if the gas vent hole is too small, there is a problem that the hole is clogged or sufficient gas can not be vented.
In such a case, sheet work between the plate material and the mold is required.
