る。Conventionally, the mold changing device for the above-mentioned processing machine has been constructed by laying a rail for a transport carriage on which the mold is mounted on one side of the processing machine, attaching the transport carriage to the side of the processing machine, and removing the sprocket from the chain member. The mold is moved in both directions between the processing machine and the transport vehicle using a drive device, and it is roughly classified according to the mounting position of the drive device.
No. and Utility Model Application No. 60-28924 exist as known techniques.

記従来技術の不具合を同時に解消したものである。On the other hand, a system in which a drive device is installed on the transport vehicle as in Japanese Utility Model Application Publication No. 60-28924 has the advantage of being applicable to existing processing machines, but the cost is high because a drive device is required for each transport vehicle. There was a drawback. As described above, all conventional mold changing devices have advantages and disadvantages, and there has been a need for a mold changing device that combines the advantages of both. [Means for Solving the Problems] Therefore, the present invention provides an example of a processing machine, in which a rail for a carrier on which a mold is mounted is laid, and a drive device is fixed on the opposite side of the processing machine across the rail. and providing a guide groove in a direction perpendicular to the rail on the mounting surface of the transport vehicle on which the mold is placed;
The drive device consists of a chain member having a hook member at the tip that engages with the mold, and a sprocket that moves the chain member forward and backward. To provide a mold changing device for a processing machine, in which the chain member slides while being fitted into a guide groove, and the mold is moved in both directions between the processing machine and the carrier by the forward and backward movement of the chain member. This simultaneously solves the problems of the prior art.
金型を乗載した搬送台車を加工機械の一側に横付けし、
駆動装置のスプロケットを作動させる。The carriage carrying the mold is placed next to one side of the processing machine.
Operate the drive sprocket.

を移動させる。When this happens, the chain member fits into the guide groove of the conveyance vehicle and moves forward, and the mold that is engaged with the hook member at the tip is pushed by the chain member. Then, when the mold reaches the specified position on the processing machine, the sprocket is stopped, the hook member is removed, and the chain member is rewound. The carriage is moved with all the chain members returned and the hook members removed from the guide grooves.
