[0002] In order to increase the special physical and chemical properties such as ferromagnetism and corrosion resistance of complex thin-walled aluminum alloy castings during production, the quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), kept warm for a period of time, and austenitized in whole or in part, and then rapidly cooled to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate to undergo martensite (or bainite) transformation. The solid solution treatment or heat treatment process with a rapid cooling process for materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass is usually called quenching, and a quenching device and a quenching method for complex thin-walled aluminum alloy castings have been developed.

[0003] In the existing complex thin-walled aluminum alloy casting quenching device and quenching method thereof, the complex thin-walled aluminum alloy casting is quenched by driving the complex thin-walled aluminum alloy casting to move to the inside of the quenching liquid under the action of the clamping device, and driving the complex thin-walled aluminum alloy casting to contact with the quenching liquid for quenching.
