Abstract: A foam molding method includes: sealing a core material and a skin material with a sealing part; and molding a foam layer on the inside of the sealing part. The sealing of the core material and the skin material with the sealing part includes sealing the core material and the skin material so that the sealing part includes a self sealing part for which an edge part of the skin material is housed in a recess provided in the core material, a clamp sealing part sealed by clamping the core material and the edge part of the skin material by foam molding molds, and a crimp sealing part arranged in a switchover part between the clamp sealing part and the self sealing part, and sealed by crimping the edge part of the skin material to the core material.

Abstract: A vacuum forming apparatus has a forming die, a plurality of holding devices, a pressing device and a pair of supplemental holding devices. The forming die has at least one suction hole for creating a vacuum. The holding devices hold a resin sheet that has been softened by heating. The pressing device moves relative to the forming die to close a space therebetween and form an airtight state therebetween. Each of the supplemental holding devices includes a clamp member and a support member. The supplemental holding devices are movably arranged to move toward each other. The clamp members clamp the resin sheet on two sides of a selected sag area where the resin sheet will be made to sag. The support members extend along two side portions of the selected sag area for supporting a bottom surface of the resin sheet where the resin sheet will be made to sag.

Abstract: A radiator core support structure for a vehicle including a radiator core support upper section extending generally along a direction of width of the vehicle. A radiator core support lower section is provided extending generally along the direction of width of the vehicle and located below the radiator core support upper section. Here, the radiator core support upper section and/or lower section are formed of metal and has an open loop-shaped cross-section which is opened rearward to form a channel. A hood lock stay is provided extending generally vertical, to connect the generally central parts of the radiator core support upper and lower sections. The hood lock stay is formed of synthetic resin and molded in a metallic mold in which the radiator core support upper section and/or lower section are located. A plurality of reinforcement ribs are formed of the synthetic resin and fixedly disposed inside the channel of the radiator core support upper section and/or lower section.
