  • Apparatus and method for producing variable configuration die
    Patent number: 5253176
    Abstract: An apparatus for producing a variable configuration die by using a plurality of pins is disclosed. The apparatus comprises a pin storing device for storing the pins therein; a pin piling device in which the variable configuration die is to be produced; a robot device for transferring the pins from the pin storing device to the pin piling device for making up the variable configuration die; and a computer-aided control device for controlling the robot means in such a manner that the pins carried by the robot means are placed onto given positions of the pin piling device to cause the variable configuration die thus made of the piled pins in the pin piling device to have a layered structure. The variable configuration die thus made up has a recessed die surface which is defined by one ends of the piled pins.
