PROBLEM TO BE SOLVED: To solve problems at the time of performing punch forming of insert pieces and injection and filling of a resin in a same position by separately performing the punch forming and the injection and filling in adjacent positions, and to provide a general-purpose method without having constraint arising from shapes or sizes of cavities.;SOLUTION: A trimming mold 1 having a punch 12 and a fixed mold 3 are arranged in parallel, and a movable mold 2 is provided so as to face both the molds for alternately closing with respect to both the molds. A trimming plate 4 is arranged between the movable mold 2 and the trimming mold 1, and is provided with a punch hole 41 formed so that a mold face having a suction mouth 22 of the movable mold 2 and the punch 12 are positioned. In a mold closing process, a band-like insert material 9 between the trimming plate 4 and the trimming mold 1 is punched into the insert piece by the punch 12 and the punch hole 41, and is pressed and formed into the same shape as the mold face by using an end face of the punch. The insert piece is sucked onto the mold face of the movable mold 2, thereafter the mold is opened, and the insert piece is moved to a position opposite to the fixed mold 3, and the movable mold 2 and the fixed mold 3 are closed so as to perform integral molding with the insert piece by filling up.;COPYRIGHT: (C)2006,JPO&NCIPI
