摘　　要：采用铸造仿真软件对铝合金舱门盖的铸造过程进行仿真模拟，设计差压铸造模具，优化差压铸造工艺参数，从而消除其铸造缺陷。实验结果表明：仿真结果与试制结果相吻合，采用该差压铸造工艺制得的铝合金舱门盖无缺陷，其力学性能显著提高，具有320～330MPa的抗拉强度和5％～6％的伸长率。The process of filling and solidification of aluminum alloy port cover was simulated to design the counter pressure casting process for aluminum alloy port cover. The results reveal that the simulated results are accordant with the trial product ones. The trial products of aluminum alloy port cover manufactured by counter pressure casting are without shrinkage porosity （hole） defects, and the mechanical properties are greatly improved, the tensile strength and elongation reach 320 MPa -330 MPa and 5%- 6%, respectively.
