Abstract
PURPOSE:To absorb the deformation of a die case due to extrusion pressure at void parts, to prevent the deformation of a die body and to reduce the weight of the whole die by forming void parts on both sides in a thickness direction of a ceramics die body fitted in the die case body. CONSTITUTION:At the time of extruding, the die case 2 in the ceramics die is deformed arcuately due to extrusion pressure given through a billet in the direction of expansion. Since there are voids 33, 34 on both sides in a thickness direction of the die body or an extrusion direction, the deformation of the die case 2 is absorbed by the void parts 33, 34 prevent the deformation of the die body 1. Accordingly, no excessive stress occurs in the die body 1, no countermeasure is required to improve the strength of the die body 1, a thin-walled die can be used, the weight and the cost of the die, as a whole, can be reduced.
