The invention belongs to the technical field of die casting, and provides a die-casting car body C column and D column structure which comprises a C column, a D column, a C column upper cross beam and a D column upper cross beam which are integrally formed through die casting, a longitudinal beam is integrally connected between the C column and the D column, and a plurality of longitudinal reinforcing ribs and a transverse reinforcing rib are arranged on the longitudinal beam. The integrated C column and D column design scheme has the advantages that the problem of insufficient torsion and bending rigidity of the C column and the D column of a traditional long-axle-distance and long-rear-overhang vehicle type is solved, the integrated high-pressure casting technology is high in production efficiency and integration degree, and therefore the working procedures are reduced, the labor requirement is lowered, and the efficiency is improved.

    本发明属于压铸技术领域,提供了一种压铸车身C柱和D柱结构,包括一体压铸而成的C柱、D柱、C柱上横梁以及D柱上横梁,C柱和D柱之间一体连接有纵梁,在纵梁上布置有若干条纵向加强筋和一条横向加强筋。本发明的优点在于一体化C柱和D柱设计方案,解决了传统长轴距,长后悬车型C柱和D柱扭转与弯曲刚度不足问题,一体高压铸造工艺生产效率高,集成度高,从而减少了工序降低人工需求和提高了效率。
