Abstract

PURPOSE: For economic fatigue strength enhancement at stress concentration portions such as sharp corners, high fatigue strength parts are assembled so that they can be changed easily.
CONSTITUTION: Load of forming or molding pressure P on corner parts 13 causes stress at concentration portions 14 as usual. This corner mounting portions 12 are assembled with corner parts 13 of high fatigue strength material and further have been subject to compressive force at shrinkable fit or pressure insertion, and as such have a prolonged life for fatigue crack generation. Even should fatigue cracks occur to the corner parts, they can be replaced easily. This means enables the permanent use of body 11' for metal mold for superplastic alloy or plastics, or for diecast mold for aluminum.
