The invention relates to the technical field of workpiece cleaning, and provides a complex runner cleaning device and method. The box body is arranged below the workpiece placing
assembly; the steel shot mixing device comprises a shot
storage tank and a water segregator connected with the shot
storage tank, one side of the water segregator is connected with a water inlet
pipe, the other side of the water segregator is connected with a first water segregation
pipe and a second water segregation
pipe, the first water segregation pipe is connected with an inner cavity of the shot
storage tank, and the second water segregation pipe is arranged in a bottom plate of the shot storage tank; a shot mixing control
assembly is arranged on the second distributive pipe and comprises a shot mixing rotary
handle and a
control rod connected with the shot mixing rotary
handle, and a shot mixing hole is formed in the
control rod; the inner
diameter of the first distributive pipe is larger than that of the second distributive pipe; the water tank and the high-pressure pump are connected, and the high-pressure pump is connected with the water inlet pipe. By means of the technical scheme, high-pressure water can be used for carrying steel shots to flush a complex runner,
product base materials are not prone to being damaged during flushing, the
flushing time is short, and no residues exist.
