Description

上記目的を達成するために、本発明の加飾成形方法は、第１金型と第２金型の間に、基材シートに転写層を設けた加飾フィルムを挟んで型締めし、前記第１金型と前記第２金型で構成された金型のキャビティに樹脂を射出し、前記転写層によって表面が加飾された樹脂成形品を前記金型から取り出す際に、前記キャビティにエアーブローを行って前記第１金型と前記加飾フィルムの間の空間を陽圧とした後に、前記空間を開放して前記陽圧を開放する、ことを特徴とする。 In order to achieve the above object, the decorative molding method of the present invention includes a first mold and a second mold, and a mold is clamped with a decorative film provided with a transfer layer on a base sheet, when the resin is injected into the mold cavity constituted by the first mold second mold, take out the resin molded product whose surface is decorated by the transfer layer from the mold, air in the cavity After blowing and making the space between the said 1st metal mold | die and the said decoration film into a positive pressure, the said space is open | released and the said positive pressure is open | released , It is characterized by the above-mentioned.

また、本発明の加飾成形装置は、第１金型と第２金型の間に、基材シートに転写層を設けた加飾フィルムを挟んで型締めし、前記第１金型と前記第２金型で構成された金型のキャビティに樹脂を射出し、前記転写層によって表面が加飾された樹脂成形品を前記金型から取り出す加飾成形装置であって、前記加飾フィルムを前記第１金型に吸着させるための吸引回路と、前記キャビティにエアーブローを行って前記第１金型と前記加飾フィルムの間を陽圧にするエアーブロー回路と、射出成形の型開きの動作に合わせて、前記キャビティにエアーブローを行って前記第１金型と前記加飾フィルムの間に形成されていた空間を陽圧とする制御部を設けた、ことを特徴とする。 Further, the decorative molding apparatus of the present invention, between the first mold and the second mold, and clamping across the decorative film in which a transfer layer on the substrate sheet, the said first mold A decorative molding apparatus for injecting resin into a cavity of a mold constituted by a second mold and taking out a resin molded product whose surface is decorated by the transfer layer from the mold, wherein the decorative film is A suction circuit for adsorbing to the first mold, an air blow circuit for performing an air blow on the cavity to make a positive pressure between the first mold and the decorative film, and a mold opening for injection molding in accordance with the operation, a space is formed between the cavity air blow the decorative film and the first mold performed provided a control unit shall be the positive pressure, characterized in that.

樹脂成形の金型は、常温（成形機を設置している部屋の室温）よりも高い一定温度（４０〜６０℃）に金型温度を制御する。常温よりも金型温度を上げることで、金型表面の空気が温まり図５（ａ）に示すように上昇気流３０となる。この上昇気流３０を高めるため、型開き時のみ、第１金型１の温度を昇温させ、成形中に冷却してもかまわない。 Mold tree butter molding, controls the mold temperature to room higher constant temperature than (room temperature of the room who has installed the molding machine) (40 to 60 ° C.). By raising the mold temperature from room temperature, the air on the mold surface is warmed and becomes an upward air flow 30 as shown in FIG. In order to increase this updraft 30, the temperature of the first mold 1 may be raised only during mold opening and cooled during molding.

Claims
