Claims

[Scope of utility model registration request]

Consisting of a lower mold that maintains a slight inclination, with U-shaped partition projections for the foam stock solution protruding from the lower mold surfaces, and mold surface portions provided inside and outside of the projections, respectively, and an upper mold that is placed on this and clamped, The molding space _C1 including the outside of the projection formed by the upper and lower molds and the molding space _C2 including the inside of the projection are mutually defined as the projection and the upper and lower mold surface portions on the virtual extension line of the projection. In a mold for molding a soft-hard cushion body that communicates through an enclosed communicating cavity, a mold surface portion outside the protrusion of the lower mold is located at a position approximately on the bisector of the volume of the space _C1 . A soft-hard cushion body for a sheet, characterized in that a distribution protrusion extending from the protrusion is provided to prevent inertial flow of the stock solution poured into the mold surface part and to evenly distribute the stock solution. mold for molding.
