Pressure testing device for tire mold

The invention discloses a pressure testing device for a tire mold. The pressure testing device comprises a pedestal, wherein a pressure testing platform and a mold loading-unloading device are mounted on the pedestal; a lifting device for unloading the tire mold from the mold loading-unloading device is mounted on the pressure testing platform, and a movable cross beam is further mounted on the pressure testing platform by virtue of a sliding device in a sliding manner and is connected with a cross beam sliding driving device; a pressurizing detection device is mounted on the bottom end face of the movable cross beam; a data detection device is arranged on the pedestal. According to the pressure testing device, the tire mold is conveyed to the pressure testing platform by the mold loading-unloading device, the movable cross beam slides towards the tire mold under the action of the cross beam sliding driving device so as to enable the pressurizing detection device to be in contact with the tire mold and pressu
