PURPOSE:To improve the productivity by providing code tracks for showing a detecting position and a metallic mold number on the surface of a metallic mold, and also providing a detector for reading those codes on a truck. CONSTITUTION:A track 32 which has recorded a code detecting position and a track 33 which has recorded a code of a metallic mold number are provided along the moving direction of a track 15 at a prescribed position of one side of the surface of a metallic mold 21. On the other hand, on the truck 15, two detectors 34, 35 of a metallic mold code are provided on the surface opposed to the track 32 and the track 33. When an injection molding machine indicates a code of a metallic mold to be used in the next time and a position number of a metallic mold custody shelf to the truck 15 in the course of a production, the truck 15 moves to a designated position. The detector 35 reads from the track 33 whether a custody metallic mold coincides with a designated metallic mold or not, receives its metallic mold to the truck 15, and carries it to the injection molding machine. According to this method, the metallic mold replacement time is shortened, and the productivity is improved. |
