ABSTRACT:
The invention provides a molding die in which a whole or a part of an exclusive portion forming a cavity can be swiftly changed while leaving a general portion in a molding machine. A fixed insert, a movable insert, a pressing plate and a slide core which correspond to an exclusive portion can be automatically attached to and detached from a fixed main die, a movable main die, a pressing rod and a slide holder which correspond to a general portion by an attaching and detaching mechanism. Further, the fixed insert, the movable insert, the pressing plate and the slide core can be integrated in a die close state by a connection mechanism. By utilizing cross-feed means of a die changing apparatus and a die opening and closing motion on a molding machine side, the exclusive portion is automatically removed from the general portion in a form of an assembly, and the exclusive portion assembly which is transferred into the molding machine from outside the molding machine is automatically mounted to the general portion.
