摘要
新能源汽车的快速发展催生了铝合金压铸件向大型化、一体化、轻量化的方向发展.一体化压铸件的生产,必须解决产品尺寸过大导致的压铸机合模力需求大增、铸件流程过长导致的模具温度平衡、生产节拍过长、产品变形、保温炉局限导致的铝液质量不高以及给汤效率问题.针对这些问题,提出一体化压铸单元设备的解决方案,包括压铸单元布局、模具的喷涂润滑、铝液的供给、模具温度的平衡控制、压铸超高真空控制技术等.
Abstract
The rapid development of new energy vehicles promotes the development of aluminum alloy die castings towards directions of large-scale,integrated,and lightweight.The production of integrated die castings should solve the problem of increased demand for clamping force caused by excessive product size,temperature balance of mold caused by excessively long casting process,excessive production pace,deformation,low quality of aluminum liquid caused by insulation furnace limitations as well as soup feeding efficiency.In this case,solutions to integrated die-casting unit equipment were proposed,including die-casting unit layout,mold spray lubrication,aluminum liquid supplement,mold temperature balance control,and control technology of die-casting ultra-high vacuum.
