The utility model discloses a negative-pressure air exhaust tar collecting tank for a low-pressure casting mold of an auxiliary frame, and belongs to the technical field of auxiliary frame die casting. The tar collecting tank is fixedly connected with the mold; the air exhaust branch pipeline is arranged on the inner side of the mold, and the air exhaust branch pipeline is connected with the tar collecting tank; according to the auxiliary frame low-pressure casting mold negative-pressure air exhaust tar collecting tank, the negative-pressure draught fan is connected with the air exhaust main pipeline for air exhaust, air generated during sand core production is exhausted at the position where the air exhaust branch pipeline makes contact with a sand core in the mold, and the air exhaust main pipeline is arranged on the outer side of the mold. When gas passes through the tar collecting tank during gas extraction, the temperature is reduced, so that liquid is formed, the liquid is solidified at low temperature
