To provide a method for manufacturing a sheet pad for a vehicle capable of efficiently manufacturing the pad for the vehicle by one time molding operation.
The method for manufacturing the sheet pad for the vehicle comprises a step of supplying a stock 6 for molding a low-density foam onto the surface of a main bottom 4 at a high site side via a nozzle 7. The method further comprises the steps of supplying the stock 6 along the slope of the main bottom 4, and moistening the overall bottom 4 to expand the stock upward to increase the thickness from the bottom 4 to the low-density foam 6a. The method also comprises the steps of supplying the stock 9 for molding a high- density foam from a nozzle 8 to a liquid reservoir 5 after the foaming of the stock 6 is advanced to a certain degree, coating the upper mold 10 on a lower mold 1 to fix the molds. This stock 9 immediately starts foaming to the high- density foam 9a. The foam 9a is expanded from the reservoir 5 to the upper side of the foam 6a in a cavity 2. The foam 9a is brought into close contact with the foam 6a and integrated with the foam 6a.
