PURPOSE:To manufacture a continuous molded product of uniform thickness all over the whole length and without thin flashes of resin by dividing a top force into a pressing mold and a press mold at least adjacent to the front of the former in a continuous press molding device provided with the top force and a bottom force. CONSTITUTION:A pressing mold 1 of a top force 3 is fixed to an upper section mounting plate 14, while a press mold 2 is hung movably up and down by inserting a bolt 16 hanging down from the upper section mounting plate 14 through a hanging plate 15 at the upper surface of the press mold and fixing by a nut, and pressed always downward by means of a number of compression coil springs 17 installed between said upper section mounting plate 14 and the hanging plate 15. Said press mold 2 is in the position lower than the pressing mold 1. When the upper section mounting plate 14 is lowered and a lowering material is press molded by the pressing mold 1, first the press mold 2 is brought into contact with the press molding material located right below, and relatively lifted up resisting to the resilient force of the springs 17 while pressing the molding material so that the recessed press surface 38 of the press mold 2 and the recessed molding surface of the pressing mold 1 are on the same level to make a space (s) zero. |
