According to the design requirements of support plate flexure mould, the preparation of designing moulds has been done. The bending process of support plate was drawn up, and the size of related parts was calculated. According to the calculation results, the suitable equipments were selected and the assembly and part drawings were drawn. The relevant technical requirements were proposed, and the design process of bending die parts for support plate was discussed.
