As shown in FIG. 2, two-stage ceramic heaters 5 and 5 ′ which sequentially heat up and down at a predetermined distance are mounted on the upper and lower portions, and a molding apparatus (bar) has a cylinder (as shown in FIG. 6). Pallet where base material preheated with 6) is placed in Normal skin preheating device equipped with a lower mold 9 for elevating and fixing the transfer rotating chain 8 of (7) and a skin material such as PVC foam with an ON / OFF heated halogen lamp 10 (e. The upper mold 12 to which the skin material preheated through) is transported and fixed along the guide rail 11 is installed.

In addition, the feed lift 4 of the feeding device (a) for supplying the substrate and the feed cylinder 13 for separating the press-molded interior materials are provided on one side, respectively, and the feed apparatus (b) of the substrate is installed in FIG. 4 or FIG. As shown in Fig. 8, the horizontal rotating chain 14 on which the pallet for substrate work 7 is placed on one side of the feeder (a) and the molding machine (bar), and the sprocket gear 15 engaged with the piston rod are shown in Figs. A plurality of fixing pins 19, 19 ', each of which is connected to the cylinder 17, which is arranged in the 16, by vertical lifting chains 18, around which the substrate is press-fitted around the inner circumference of the pallet 7, which is penetrated therein. On one side of the cylinder 17, a motor 20 for forward and reverse driving of the horizontal rotating chain 14 is mounted, and as shown in FIG. 3, the base material preheating apparatus (D) and the molding apparatus (bar). In the lower part of the connecting chain 21 for transferring the pallet (7) from which the interior material is separated to the substrate supplying device (a) It is connected to the horizontal rotating chain (14).

As described above, the present invention has been made of the input device (A) of the base material made of polyurethane material and the input device (B) of the skin material made of PVC foam material and the preheating method of the base material and the skin material different from each other. Through the preheating device (D), each structure of the molding device (bar), which is compression-molded into a certain type of interior material such as head lining, is improved, so that the supply and transfer of the substrate and the skin material can be carried out quickly and conveniently.
