PROBLEM TO BE SOLVED: To provide a molding method of a multicolored molded product enhanced in its appearance capacity by avoiding the abutment to a mold due to a dividing bar for dividing a cavity, and a mold therefor. SOLUTION: The cavity C formed by the mold clamping of a movable mold 41 and a fixed mold 42 is demarcated into a plurality of, that is, at least two cavities C1 and C2 by the operation of the dividing bar 50 and, at the time of demarcation of the cavities C1 and C2 due to the dividing bar 50, a gap (d) is set between the molding surface of the movable mold 41 and the leading end surface 50a of the dividing bar 50 to avoid the draw damage caused by the abutment of a conventional dividing bar. Then, air is blown against the gap (d) from the air supply system provided to the dividing bar 50 and the leakage of a resin to the outside of the cavity is regulated by air sealing action.
