A foam molding apparatus and a foam molding method thereby are proposed. The foam molding apparatus includes a foaming agent supply unit configured to supply a foaming agent, a molten resin supply unit configured to supply molten resin, a fixed mixing unit configured to produce a foaming resin-critical solution by mixing a foaming agent supplied from the foaming agent supply unit and molten resin supplied from the molten resin supply unit through a rod-shaped body, and a molding unit configured to mold a foam molding product using the foaming resin-critical solution supplied from the fixed mixing unit. Accordingly, it is possible to produce a foaming resin-critical solution by uniformly mixing a large amount of high-viscosity gel-state molten resin and a high-pressure compressed and low-viscosity foaming agent, using high-strength multiple channels.

An apparatus includes a first flow path member configured to define a first section of a flow path, a second flow path member configured to define a second section of the flow path, and a valve unit configured to suppress backflow in the flow path. The first section and the second section are connected via the valve unit. The valve unit comprises a displaceable valve body and a first valve seat portion. The first valve seat portion is configured to close the flow path in a case where the valve body abuts. The first valve seat portion is configured to abut on the first flow path member and is made of a material having higher hardness than that of a material constituting the first flow path member.
