Die casting device and method for thin-wall aluminum alloy die casting

The invention discloses a die casting device and method for thin-wall aluminum alloy die castings, and relates to the technical field of aluminum alloy die castings, the die casting device comprises a rack, a material injection chamber is fixedly connected to the top of the rack, a fixed die assembly is fixedly connected to one side of the material injection chamber, and a movable die assembly is fixedly connected to the top of the rack; and the fixed track is arranged above the machine frame. Through the arrangement of the alarm unit, in the die casting discharging process, an insertion block moves to the position above a clamping groove, when a die casting falls off, a reset spring drives a movable rod and an L-shaped pressing block to move, the L-shaped pressing block makes contact with a pressure sensor, at the moment, the pressure sensor feeds back a signal to a controller, and the controller starts an alarm to give an alarm; according to the die casting monitoring device, monitoring on the die casting i
