• a first functional part holder (7) for a first type of functional part and at least one of a further functional part holder (8) for a further type of functional part or a placeholder element (10),
• a changing device (11), by which the first functional part holder (7) and at least one of the further functional part holder (8, 9) or the placeholder element (10) as a placeholder for a functional part holder (7, 8, 9) are positionable in a respective use position thereof on the mold cavity (6),
• the changing device (11) comprises:
• at least one rotary holder (13), on which the first functional part holder (7) and the at least one of the functional part holder (8, 9) or the placeholder element (10) are at least one of arranged or formed,
• a driving device (14) for the at least one rotary holder (13), and
• a locking device (17) comprising a locking lever (18) with at least one locking pin (19) arranged on the locking lever (18), the at least one locking pin (19) configured to engage the at least one rotary holder (13) to fix the at least one rotary holder (13) in a selected rotational position.
