There is provided an in-mold foam molding apparatus affording a
significantly simpler design for a molding apparatus capable of molding
molded portions comprising bead starting materials having different
properties into a unitary molded article, and effectively preventing
various drawbacks associated with the provision of partitioning members;
and an in-mold foam molded article devoid of flash projecting from its
visible surfaces. There are provided partitioning members (32), (40) for
partitioning into a plurality of partitioned mold chambers a mold cavity
(13) defined by a core mold (11) and a cavity mold (12), these
partitioning members (32), (40) being arranged such that at least a
portion of the plurality of partitioned molding sections (11a), (11b)
constituting the partitioned mold chambers within the core mold (11) are
unitary, and filling units are provided to each partitioned mold chamber
for filling thereof with a bead starting material, adjacent partitioned
mold chambers being fillable with bead starting materials of different
properties.
