Description

technical field [0001] The invention relates to a dual-mode automatic casting machine for pouring aluminum piston blanks by rotating 90° and a method for using the same, belonging to the technical field of piston casting. Background technique [0002] As the engine explosion pressure exceeds 20MPa and the gas temperature exceeds 400°C, the high temperature and high pressure working environment has more stringent requirements on the internal combustion engine, and the improvement of the overall performance of the internal combustion engine mainly depends on the improvement of key components. The piston is the heart of the internal combustion engine. It plays a vital role in the whole engine working process and exhaust emission. [0003] At present, the piston casting machines on the market mainly include the machine body, electrical system, hydraulic system and cooling system. The pouring mode is that the operator manually pours the aluminum liquid, manually takes the piston ...
