PROBLEM TO BE SOLVED: To provide a mold which is easily replaceable of a replacement die corresponding to an undercut. SOLUTION: A mold 1 includes: a stationary mold 2; a movable mold 3 which forms a space 16 corresponding with a molded article 15, between the stationary mold 2 and the movable mold 3; a replacement die 21 which is detachably built in the movable mold 3 and includes an oblique through hole 31; an in-die slide 23 which includes a projection part 33 for forming an undercut 15c and is formed equal to or shorter than the thickness T of the replacement die 21 and further, is slidably arranged in the through hole 31, with such a behavior that the in-die slide 23 moves obliquely in the direction where the projection part 33 leaves the undercut 15c, when pushed facing the stationary mold 2; an ejector plate 35 which moves facing the stationary mold 2; and an ejection pin 41 which extends facing the in-die slide 23 from the ejector plate 35 and ejects the in-die slide 23 toward the stationary mold 2.
