发明名称 SYNTHETIC RESIN MOLDING, AND MOLDING METHOD THEREFOR
摘要 PROBLEM TO BE SOLVED: To provide a molding method for a synthetic resin molding, capable of gracefully demonstrating an ornamental design surface of a molding body by suppressing a turbulence of the flow of molten resin in a peripheral edge part in injection molding even when the peripheral edge part of the molding body forms a complicated and unstable outer shape in which a notch part is formed on a flange part continuing to a bent part bent to a rear surface side, and a resin molding obtained by the same.SOLUTION: A molten metallic colored resin material which is injected from a gage G set in a terminal position at one side part in the lengthwise direction of a flange part 4 in injection molding of a motor vehicle trim 1 uniformly flows to a trim body 2 side owing to that the circulation is once narrowed in a part corresponding to a thin wall part 6 of a bent part 3. With this, even when there occurs a turbulence of the flow of molten resin in a connection corner part between the flange part 4 and the bent part 3, and the periphery of a notch part 5 of the flange part 4, the turbulence of the flow is mitigated in the part corresponding to the thin wall part 6 and is suppressed from spreading to the trim body 2 side.SELECTED DRAWING: Figure 1
