摘要： A method for manufacturing a multihardness foamed article, including the steps of, placing a mold for foaming such that its bottom surface is inclined with respect to the horizontal plane, pouring a first liquid formulation which will form a portion having a certain hardness designed to constitute the surface area of the foamed article at or adjacent to a higher point of the inclined bottom surface, and allowing the formulation to flow and spread over the entire bottom surface as a continuous thin layer while sticking at its undersurface to the bottom surface, immediately after pouring of the first formulation, pouring a second liquid formulation which will form another portion of another hardness designed to constitute a portion other than the surface area of the foamed article at or adjacent to the higher point, and allowing the second formulation to flow and spread over the flowing and spreading first formulation as a second continuous thin layer which will not commingle with the first layer, and allowing these two layers to foam and cure respectively in a contiguous but independent state to form the multihardness foamed article which has a clear and distinct common boundary defined between portions of different hardness and is combined unitarily along the common boundary. A third liquid formulation which will form a portion of yet another hardness designed to constitute yet another portion of the foamed article may be poured at or adjacent to the higher point or onto side recesses of the mold, and allowing the third formulation to flow and spread over the flowing and spreading second formulation as a third continuous thin layer which will not commingle with the second layer.
摘要翻译：一种制造多硬质发泡制品的方法，包括以下步骤：将发泡模具放置成使其底面相对于水平面倾斜，浇注形成具有一定硬度的部分的第一液体制剂，其设计成构成发泡制品的表面积在倾斜的底部表面的较高点处或附近，并且允许制剂作为连续的薄层在整个底部表面上流动并分布，同时在其下表面附着在底部表面上倾倒第一制剂，注入第二液体制剂，该第二液体制剂将形成另一硬度的另一部分，该硬度被设计成构成除了较高点处或附近的发泡制品的表面积以外的部分，并允许第二制剂流动和扩散超过流动和传播的第一配方作为不会与fi混合的第二连续薄层并且允许这两层分别在连续但独立的状态下发泡和固化以形成多硬质发泡制品，其具有在不同硬度的部分之间限定的明确和不同的公共边界，并沿着公共边界一体地组合。将形成设计成构成泡沫制品的另一部分的又一硬度的一部分的第三液体制剂可以在模具的较高点或侧面凹部处或邻近处倾倒，并允许第三配方流动并铺展超过流动和扩散的第二配方作为不与第二层混合的第三连续薄层。
