摘要： A molded foam containing no voids and a mold for forming such a molded foam are provided. A molded foam 5 has an external corner 5a where a small rib 10 is formed and a recessed step 7 where thin plate-like ribs 11 are formed. The rib 10 has a triangular cross-sectional shape in a direction perpendicular to the longitudinal direction of the recessed step 7. The rib 10 is tapered from the base to an end thereof in a direction in which the rib 10 protrudes. The ribs 11 are arranged at intervals in the longitudinal direction of the recessed step 7.

摘要翻译： 提供不含空隙的成型泡沫体和用于形成这种模制泡沫的模具。 模制泡沫体5具有形成小肋10的外部拐角5a和形成薄板状肋11的凹进步骤7。 肋10在垂直于凹进步骤7的纵向的方向上具有三角形横截面形状。 肋10在肋10突出的方向上从基部向其端部逐渐变细。 肋11在凹进步骤7的纵向上间隔设置。
