The invention discloses an aluminum alloy mould capable of automatically controlling temperature. The aluminum alloy mould capable of automatically controlling the temperature comprises an aluminum alloy lower mould body, an aluminum alloy upper mould body, a mould cavity, temperature-controlling pipes, an electronic valve, a controller, a transmission pipe, and temperature sensors. The temperature-controlling pipes are correspondingly arranged inside the aluminum alloy upper mould body and the aluminum alloy lower mould body; one end of the transmission pipe is connected with the temperature-controlling pipes, and the other end of the transmission pipe is connected with the electronic valve; the temperature sensors are arranged on the inner parts of the aluminum alloy upper mould body andthe aluminum alloy lower mould body; and the electronic valve and the temperature sensors are electronically connected with the controller. According to the aluminum alloy mould capable of automatically controlling the temperature, in the injection molding process of products, the controller controls the electronic valve according to written injection mould temperature parameters to control the flow speed and the flow amount the water or oil inside the temperature-controlling pipes so as to control the temperature of the aluminum alloy mould, and heat dissipation, heating and temperature controlling of the aluminum alloy mould are realized; and automatic control is achieved, and aluminum alloy mould is simple in structure, low in cost, high in practicability, and suitable for large-scaleinputting use.
