本文从模具材料性能入手,确定在选用碳工钢T8-T12或T8A-T12A做模具时,在淬火硬度达:HRC56—62时,应视为脆性材料,并以此出发,应用第一强度理论,确定了设计模套壁厚的算式。
In this paper, starting from the mold material properties, to determine the use of carbon steel T8-T12 or T8A-T12A as a mold, the quenching hardness of: HRC56-62 should be considered as brittle material, and proceed with this, the application of the first strength theory , Determine the design of mold wall thickness formula.
