ABSTRACT:
The invention achieves a more effective die changing work, reduces a time required for performing die changing of work of a die, and improves an operational availability of a molding machine, in various kinds of molding dies. A die changing operation can be efficiently performed by drawing out an exclusive portion which is automatically attached to and detached from a general portion of a molding die, from the general portion by a feeding means and pressing the exclusive portion to the general portion. Further, the exclusive portion (an old insert) drawn out to a predetermined position from the general portion can be carried out to an outer side of a die casting machine by a carrying means, and another exclusive portion (a new insert) can be carried in to a predetermined position within the machine from the outer side thereof, within the machine in a die unclamp state. A subject to be treated by the feeding means and the carrying means in the die changing operation is only the exclusive portion, and the subject to die changing can be made compact and light in comparison with the case that a whole of the die is changed.
