PROBLEM TO BE SOLVED: To efficiently manufacture a profile molded article. SOLUTION: A first molding stage for molding a main body part and a second molding stage for molding the rubber cap 3 mounted on the undercut part of the main body part 1 are provided. Both stages can be changed over by the reversal operation of a rotary platen 7. A slide core pin 15 for molding the undercut part is incorporated in a movable mold in an up and down movable manner. The slide core pin 15 is held to a rising position in the first molding stage but, when a follower slider 18 is laterially slid by a cam plate in the second molding stage, a core back plate 14 having the slide core pin 15 is allowed to fall by the guide operation of the cam groove 19 of a cam pin 17 and the slide core pin 15 falls in the undercut part and, therefore, the molding space of the rubber cap 3 is formed.
