Abstract
Provided with a compact in-mold coat injection device where the accuracy of the amount of injecting liquid coating agent (e.g., coating composition) is high and manufacturing yield of the coating composition is good. An in-mold coat injection deviceconfigured to hold a molding base materialon one mold, press the other moldagainst the one moldto cover the molding base materialand inject a predetermined amount of coating compositioninto a coating gapformed between an inner surface of the other moldand a surface of the molding base material. A measuring cylinderof the coating compositionis used as an extrusion cylinder. Thus, a piping connecting the measuring cylinderand the extrusion cylinder can be omitted. When introducing the coating compositioninto the measuring cylinder, an injection portis closed by a gate valve. Thus, the accuracy of the measurement is increased. A circulating passage and a circulation pump of the coating compositionare not used. Thus, the device is made compact and the manufacturing yield of the coating compositionis increased.
