The invention discloses an integrated front cabin manufacturing method, an integrated front cabin structure and a lower vehicle body assembly with the integrated front cabin structure. The integrated front cabin manufacturing method comprises the steps that pouring liquid is poured into a front cabin mold, and vacuumizing operation is conducted on the tops of shock absorption tower molds on the left side and the right side of the front cabin mold, the left side and the right side of the rear portion and the middle portion of the front cabin mold and a feeding pipe of the pouring liquid; and pouring liquid overflowing from the top of the damping tower mold is guided out to a cinder ladle. The front cabin manufactured through integrated die casting is only provided with one part and has high integration, good lightweight performance, good front cabin size precision and excellent collision performance, the vehicle body rigidity and torsional rigidity of the white vehicle body are effectively improved, manufacturing is convenient, and the forming performance is excellent.

    本发明公开了一种一体化前机舱制造方法、结构及具有该结构的下车体总成,包括将浇筑液浇筑至前机舱模具内,对前机舱模具的左右两侧的减震塔模具的顶部、前机舱模具的后部左右两侧和中部以及浇筑液的进料管进行抽真空操作,将减震塔模具的顶部溢流出的浇筑液导出至渣包。通过一体式压铸制造的前机舱仅有一个零件,具有高集成性、良好的轻量化性能,前机舱尺寸精度好、碰撞性能优,并且有效提升了白车身的车身刚性和扭转刚度,制造方便,成型性能优。
