Abstract

A foam molded article mold includes a lower mold with a cavity space; an upper mold formed with an upper mold face portion facing a lower mold face portion of the cavity space when the upper mold has been brought together with the lower mold; a partitioning wall that projects out from the upper mold face portion, and that configures a first parting line between the partitioning wall and the lower mold face portion in a state in which the upper mold has been brought together with the lower mold; and a partition that projects out from the lower mold face portion, and that, in a state in which the upper mold has been brought together with the lower mold, partitions the cavity space together with the partitioning wall to form plural cavities, and that configures a second parting line between the partition and the partitioning wall.

First claim

The invention claimed is:

1. A foam molded article comprising: a main body that is formed from foamed resin that is molded using a mold comprising an upper mold and lower mold and that includes an upper face, a lower face, an outer periphery connecting the upper face and the lower face together, the outer periphery including a first side face, a second side face, and a third side face, the first side face being adjacent the second side face, and the third side face being opposite the first side face, a first edge defined by the lower face intersecting the first side face, a second edge defined by the lower face intersecting the second side face, a third edge defined by the upper face intersecting the third side face, a fourth edge defined by the lower face intersecting the third side face; and a parting line that is formed by the upper mold that has been brought together with the lower mold and is configured as a ridge that is provided at the outer periphery and that extends from a first point on the first edge, along the second edge, and also extending along the third edge, without transiting the fourth edge.
