Aluminum alloy low-solid-phase pressure casting control method and system

The invention discloses an aluminum alloy low-solid-phase pressure casting control method and system. The method includes the following steps that 1, molten aluminum temperature in a holding furnace is acquired; 2, whether the acquired molten aluminum temperature is within a set range or not is judged; and 3, if the molten aluminum temperature is within the set range, a pressure casting machine iscontrolled to start working in an automatic mode, or else, the pressure casting machine is controlled to be switched off and an alarm is given. Compared with the prior art, according to the aluminumalloy low-solid-phase pressure casting control method and system, temperature feedback control is added between an existing GISS control system and the pressure casting machine, when the molten aluminum temperature exceeds limits, the automatic switching-off function of the pressure casting machine is achieved, castings with poor quality cannot be produced, thus, economic benefits are increased, and the pressure casting qu
