Double-oil-cylinder connecting mechanism for sliding block core pulling of ultra-large die-casting die

The invention relates to the technical field of die-casting dies, in particular to a double-oil-cylinder connecting mechanism for core pulling of a sliding block of an ultra-large die-casting die, which comprises a support frame and an oil cylinder placed in the support frame, a connecting mechanism is arranged in the support frame, and a fixing mechanism is arranged at the bottom of the support frame. A pressure control mechanism is arranged on the back face of the supporting frame. Through the arrangement of the connecting mechanism, the fixing mechanism and the pressure control mechanism, the two oil cylinders can be conveniently connected, meanwhile, the front-back distance and the close distance of the two oil cylinders can be adjusted, the application range is further increased, the device can be suitable for oil cylinders of different models, oil pressure can be well controlled, and the practicability is high. And the two oil cylinders can stretch out and draw back better at the same time in the using
