Abstract

L'invention concerne le moulage des blocs de mousse de matière plastique. Elle se rapporte à un moule qui comprend un fond, muni de saillies 4, des parois latérales 6, 8, 10, 12 et un couvercle 22. Les parois latérales ont leurs bords verticaux reliés par des dispositifs élastiques 16 et peuvent glisser sur le fond, jusqu'aux butées 4, si bien que la mousse placée dans le moule peut gonfler librement et peut former un bloc isotrope. Application à la préparation de blocs isotropes de mousse de matière plastique utilises dans l'industrie pétrolière.
