The invention discloses an automatic weight adding piston type pressure gauge, which belongs to the technical field of piston type pressure gauges, and comprises a pressure gauge main body, the top of the pressure gauge main body is connected with a connecting pipe orifice used for being connected with an external instrument to be calibrated, and the front side of the pressure gauge main body is provided with an adjusting handle used for adjusting pressure. The top of the pressure gauge body is provided with a weight calibration disc, and the top of the weight calibration disc is fixedly provided with a discharging mechanism used for bearing calibration weights. According to the discharging mechanism, resetting of the air cylinder is controlled to drive the lifting rod and the weight to be upwards separated from the discharging sliding base, the fixing base can move to the top of the discharging mechanism through movement of the transverse moving module, and at the moment, the supporting base falling again ca
