Abstract

PURPOSE:To make it possible to insert also in a rising part of a mold and an upper mold, simplify insert molding, enable the insert molding of a flat face, and particularly make it effective in press molding by embedding magnets in a mold in the neighborhood of a metal insert fixing position. CONSTITUTION:Cylindrical permanent magnets 4a-4d are embedded in an upper mold 1 and a nut inserting nest 5 is provided in a lower mold 2. The molds 1 and 2 are attached, for example, to a hydraulic pressing machine of 500 ton. After the temperature of the molds is raised, for example, to 160 deg.C, the molds 1 and 2 are opened. Sheet metal inserts 6a and 6b are provided in the upper mold 1 and a nut 7 is provided in the lower mold 2. A stampable sheet is heated in a far-infrared heating furnace at, for example, 300 deg.C for 6 minutes, thereafter, it is immediately charged in the molds 1 and 2, mold clamping is performed, and dwelling is performed with a pressure of, for example, 200kg/cm<2> for 30 seconds so as to obtain a molded piece. The obtained molded piece can insert the inserts 6a, 6b and the nut 7 into predetermined positions.
