초록 ▼

A method for forming a pattern onto an article during injection molding thereof. A pattern-bearing film is heated and softened by a heating board. The softened pattern-bearing film is transferred to the cavity surface of a female mold. Thereafter, the female mold and a male mold are closed. Then, a molten resin is injected into the cavity. When a pattern-bearing film is brought in contact with and heated by the heating board, marks or impressions of air blow holes on the surface of the heating board remain on the pattern-bearing film. To prevent the formation of these marks or impressions, a square-shaped holding frame is fixed on the surface of the heating board. The peripheral portion of the pattern-bearing film is held on the surface of the holding frame. Thus, while the pattern portion of the pattern-bearing film is spaced apart from the surface of the heating board, the film is heated. To keep the pattern-bearing film uniformly spaced from the surface of the heating board, air is supplied to the inside of the holding frame.
