PURPOSE:To reduce the manufacturing man-hours, facilitate the manufacturing work, and at the same time enhance the economical efficiency of a molding tool by a method wherein the peripheral portion of a base layer material is trimmed before the material is taken out of the tool. CONSTITUTION:After the finish of pressing, when necessary, both materials 14 and 17 are cooled down under the state that both forces 2 and 3 are kept on pressingly contacting with each other. On the other hand, at a proper time after or nearly simultaneous with the pressing, fluid pressure cylinders 10 are put into actuation so as to eject cutting blades 8 beyond the tool surface of the top force 3 in order to trim only the base layer material portion located at the peripheral portion A of the top force 3. In this case, only the base layer material 17 is cut off, while the skin material 14 is not cut off. After that, the top force 3 and the bottom force 2 are parted from each other so as to release both the materials bonded with each other from the forces. As for both the taken-out materials 14 and 17, the peripheral portion of the skin material 14 extends itself beyond the peripheral edge of the base layer material 17. Thus, after some part of the extended portion X is trimmed as necessary, the extended portion X is folded back to the base layer material side and secured to the base layer material by means of adhesive, fittings or the like in order to complete a composite molded part 25. |
