    Abstract: A quick change tool for use in die casting. The tool includes a pair of frame plates permanently bolted into a die casting machine. A first frame plate bolted to an upper platen of the machine and a second frame plate bolted to the lower platen. Each frame or plate can include a plurality of slotted rails that form a slotted rectangular periphery groove adapted to accept a standard size periphery ear attached to an existing die. This allows a die casting operation to retrofit old dies to fit the system while also making new dies to fit. The system allows for dies to be quickly slid out of a casting machine substantially reducing set up time in a die casting operation while still allowing for a precise relocation of the dies at each change over.
