PROBLEM TO BE SOLVED: To provide a cavity formation part for an insert molding machine that has a simple structure and can position an insert member at a more accurate position, and to provide an insert molding machine, and an insert molding method.SOLUTION: A cavity formation part 1 for an insert molding machine 100 is provided with a pair of holding blocks 4, 5 slidably in a columnar restriction hole 7 communicating with a cavity 6 formed from molds 2, 3 and the pair of holding blocks 4, 5. An inner wall 71 of the restriction hole 7 can restrict a position shift of an insert member A in a direction perpendicular to the direction in which the restriction hole 7 extends, and the pair of holding blocks 4, 5 can hold the insert member A having its position shift restricted by the restriction hole 7 within the restriction hole 7 and move the insert member to a fixation position in the cavity 6, and also can fix the insert member A at the fixation position. |
