MOLDING METHOD FOR CAR FRONT FENDER AND MOLD THEREOF

摘要

PURPOSE:To prevent production of a weld mark and to prevent partial lowering of an impact strength, by a method wherein a plurality of molten resin flows are created radially from an arch-shaped part forming part. CONSTITUTION:A mold 4 has a cavity 5 corresponding to the shape of a front fender F, and an arch-shaped part forming part 5a of the cavity 5 has a plurality of gates 6 which are open along an arch surface at given intervals. A reinforcing rib forming groove part 7 having a given width is formed in the cavity 5 and in a portion which has a longest distance in a radial direction between the arch-shaped part forming part 5a and the end wall of the cavity. The gates 6 are aligned, and this causes a plurality of molten resin flows R to be created in the cavity 5 radially from those gates 6, resulting in preventing production of a weld mark.
