Abstract:
An apparatus for forming a pattern onto an article during an injection molding thereof, comprising:feed means that feeds a pattern-bearing film to a molding position where a male mold and a female mold are opposed; a heating board that heats said pattern-bearing film so as to soften it, said heating board having a heating surface and being movable into and away from a space between said male mold and said female mold; transfer means that transfers said pattern-bearing film to an internal surface of said female mold so as to contact said pattern-bearing film with said internal surface; closing means that causes said male mold and said female mold with said pattern-bearing film therein to approach each other to form a closed molding cavity; a resin injecting device that injects a molten resin into said cavity to form a molded article to adhere said pattern-bearing film to the surface of said article; and a pair of holding members, arranged on both sides of the female mold to hold the heating board so as to be opposed to a parting surface of the female mold, said holding members being movable along a direction connecting the male and female molds so as to press the heating board to the female mold, wherein said holding members are each in a U shape having parallel opposite arms defining a space therebetween, said arms extending in a direction parallel with said parting surface of the female mold said heating board being slidingly movable into said space.
