The rear floor structure comprises a rear floor body and a rear floor frame which are integrally cast and formed, the rear floor frame comprises a left longitudinal beam, a right longitudinal beam and a cross beam set, the cross beam set comprises at least two cross beams, and the cross beams are connected between the left longitudinal beam and the right longitudinal beam; the longitudinal beams and/or the cross beams are provided with first grooves with downward openings, and a plurality of reinforcing ribs are arranged in the first grooves. The rear floor structure is manufactured through the integrated casting forming process, the self weight of the rear floor structure can be effectively reduced, the overall performance of the rear floor structure is optimized, the production cost of the rear floor structure is reduced, and the production efficiency is improved; according to the rear floor structure, the first grooves with the downward openings are formed in the longitudinal beams and/or the cross beams, the overall bending rigidity and structural strength of the rear floor structure can be effectively improved, and meanwhile the casting difficulty and cost of the rear floor structure are reduced.

    本发明公开一种后地板结构及铸造模具,后地板结构包括:一体铸造成型的后地板本体和后地板框架,后地板框架包括左纵梁、右纵梁和横梁组,横梁组包括至少两个横梁,横梁连接在左纵梁以及右纵梁之间,纵梁和/或横梁具有开口向下的第一凹槽,第一凹槽内设置有多个加强筋。采用一体铸造成型工艺制造后地板结构能够有效减轻后地板结构的自身重量,优化后地板结构的整体性能,降低后地板结构的生产成本,提高生产效率;通过在纵梁和/或横梁上设置开口向下的第一凹槽,能够有效提升后地板结构整体的弯扭刚度和结构强度,同时,降低后地板结构的铸造难度和成本。
