PROBLEM TO BE SOLVED: To eliminate generation of shrink-marks on a designed face. SOLUTION: On a rear face R of a side molding 11, there is provided a grade which slants in a direction parting from slide cores 21a and 21b in moving the slide cores 21a and 21b after completion of injection. Thus, even when the slide cores 21a and 21b move in the direction of the arrow, the rear face R of the side molding 11 is prevented from being gouged at the ends of the slide cores 21a and 21b. As a result, generation of shrink-marks on a designed face D of the side molding 11 can be prevented. |
