Double-path air inlet type counter-pressure casting equipment

Two-way air inlet type counter-pressure casting equipment comprises an upper tank and a lower tank, a casting mold is arranged in the upper tank, an aluminum water tank is arranged in the lower tank, the aluminum water tank is connected with the casting mold through an aluminum water pipeline, the upper tank is connected with a first air pipe, and the lower tank is connected with a second air pipe. And the first air pipe is simultaneously connected with the first pipeline and the second pipeline. According to the counter-pressure casting equipment, common one-way air inlet is changed into two-way air inlet, in the whole counter-pressure casting process, the efficiency of counter-pressure air inlet is improved, air pressure in the upper tank is easier to adjust, and the service life of the counter-pressure casting equipment is prolonged. The process problem that under the negative pressure condition, differential pressure casting equipment can only conduct exhaust work through an exhaust plug and a reticulate
