上げられると型閉じが完了する。A fiber-filled resin material impregnated with a thermosetting resin such as an unsaturated polyester resin, that is, a so-called SMC or BMC molding material is supplied between the female mold 1 and the male mold 2 in which the packing 10 is thus inserted. . Next, when the male die 2 is moved upward and the core portion 6 is fitted into the female die 1, the fitting surface 8 of the male die 2 is guided by the fitting surface 7 of the female die 1 to be fitted. From the middle of the fitted state, the inside of the mold is sealed by sliding with the packing 10. At this time, the vacuum pump (not shown) is operated to push up the male mold 2 while depressurizing the inside of the mold. When the upper surface of the core portion 6 of the male mold 2 is pushed up to the position of the chain double-dashed line in FIG. 1, the mold closing is completed.
