PURPOSE:To mold a light wt. rear parcel shelf having excellent strength, by a method wherein an upper mold is engaged with a lower mold in a compressed state and air is sent from an air blow-off port under pressure to mold the first base plate and the second base plate into a shape having a space part between both base plates. CONSTITUTION:After a lining sheet 13 and the first base plate 14 are placed on a press mold, an air blow-off port 12 is set to as to be held between the first base plate 14 and the second base plate 15 made of a thermoplastic resin. Upper and lower molds are engaged in a compressed state and air is sent from the air blow-off port 12 under pressure to integrally mold the lining sheet 13, both base plates 14, 15 made of the thermoplastic resin and a skin material 16 along the cavity shape of both molding surfaces 10a, 11a and a space part 17 is formed between the first base plate 14 and the second base plate 15. The molded product obtained is taken out and the engaging edge part of the molded product is subjected to trimming processing to obtain a rear parcel shelf 20. The rear parcel shelf 20 consists of a general part 20a wherein respective members are strongly laminated and a reinforcing part 20b having the space part 17 between the resin base plates and is extremely reduced in bending deformation and excellent strength is obtained. |
