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.

Abstract: A conveyor has a rotary encoder for measuring the amount of rotation of a driven sprocket having an intermittently drivable chain reeved therearound, and a processor for processing the measurement obtained by the encoder as operation support operating data corresponding to the amount of rotation of the driven sprocket. The processor determines a reference position of the chain in time series when the chain is moved a distance at a time by intermitting driving, computes the actual position of the chain corresponding to the reference position based on the measurement obtained by the encoder, and computes the deviation of the actual position of the chain from the reference position.
