A MOULD AND A METHOD OF ITS MANUFACTURE

摘要

A mould for casting in one piece of a tool with a working component of steel and a body of grey iron with an interconnection zone there between has a first model section (2) corresponding to the working component and a second model section (3) corresponding to the body. The model sections are in contact with one another along a contact plane (4) which is horizontal and planar and which represents the interconnection zone. In a method for producing a mould for one piece casting of a tool with a working component of steel and a body of grey iron with an interconnection zone therebetween, a first model section (2) is produced corresponding to the steel and a second model section corresponding to the grey iron. The model sections are brought into contact with one another with the contact surface horizontally aligned and with the first model section (2) lowermost.
