  When the mold A is placed on the base A, the engagement between the hook 52 and the engaging portion 6a of the mold A is released. Thereafter, in order to carry in the mold C to be used next from the mold storage space 10 to the processing apparatus, the hook 17 of the mold storage space 10 and the engaging portion 62 of the base C are engaged, and the hook 61 and the base of the base C are engaged. When the engaging portion 62 of A is engaged to connect the base C and the base A, the hook 17 moves the mold C to the reference space 2 along the guide rail 16 by the action of the motor 18 while maintaining the connected state. The mold A is transferred to the mold storage space 30.

The mold C conveyed to the reference space 2 releases the connection with the base A, and releases the engagement between the engaging portion 62 of the base C and the hook 17 of the mold storage space. In order to separate the mold C from the base C, the hook 52 of the mold loading / unloading mechanism 50 and the engaging portion 6a of the mold C are engaged, and the hook 52 is moved along the guide rail 63 by the action of the motor 53. C is separated from the pedestal C, transferred to the transfer table 51, and further transferred into the processing apparatus. Thereby, as shown in FIG.5 (h), the metal mold | die C can be carried in to a processing apparatus.
As can be seen from the above operation, by providing the base retracting means 70 and retracting the base A, an arbitrary mold can be moved to the mold storage space 10 adjacent to the reference space 2 during processing using the mold A. It can be made to wait, and the time required for mold replacement can be greatly shortened.

(Second embodiment)
Next, a second embodiment (not shown) of the present invention will be described. In the second embodiment, in the mold storage space 30 in the area 2, as in the area 1, the hook for moving the mold in the horizontal direction, the motor for moving the hook via the roller chain, and the hook move. And a guide rail to be provided. Further, an engaging portion is provided at the center of both ends of the pedestal 60 in the horizontal direction so that the hook provided in the area 2 and the engaging portion of the pedestal 60 can be engaged with each other. The difference from the first embodiment is that the hook 61 for connecting them to each other is eliminated. As a result, the molds in the mold storage spaces 30 and 40 can be transported in the horizontal direction without being connected to the molds stored in the mold storage spaces 10 and 20 in the area 1, and the mold transport is further performed. Can be shortened. Other configurations are the same as those of the first embodiment. The configuration of the mold storage space 40 constituting the second floor portion of the mold storage area 2 is the same as the configuration of the mold storage space 30.
