PURPOSE:To mold an integrally molded form of a sheet material and an injection molded form simply and easily, by a method wherein the flat plate type sheet material is pinched in one part of a mold, thereafter, the mold is closed to form the sheet material into a predetermined configuration, provided to the mold, while normal injection molding is effected so as to be neighbored to the sheet material. CONSTITUTION:A flat plate type sheet material 13 is inserted into a position, opposing to one part 11a of the core 11 of a mold 10, under a condition that the mold 10 is opened. Next, the sheet material 13 is pinched into a space between the mold core 11 and the cavity 12 of the mold by the closing of the mold 10 to deform the sheet material 13 by the heat of the mold and a pressure generated at the time of closing the mold 10 in accordance with the configuration of the gap between the core 11 of the mold and the cavity 12. Subsequently, molding material is poured through the gate 12b of the cavity 12 whereby an injection molded form may be molded in the space for injection molding, which is defined between the core 11 and the cavity 12. In this case, a neighboring part between the injection molded form 14 and the sheet material 13 is connected whereby the final molded form 15, integrating the sheet material 13 with the injection molded form 14, may be molded by a single mold operation. |
