Supporting structure used for production mould of aerospace composite material

The invention discloses a supporting structure used for a production mould of an aerospace composite material. The supporting structure comprises a supporting seat, a bearing element, a rotary screw,a permanent seat, a connecting element, a supporting element, a side base, an opening and an auxiliary blanking device. The top of the side base is provided with the auxiliary blanking device, the auxiliary blanking device can collect discharged parts, and in addition, a slow descent plate is installed in a collection tank in the auxiliary blanking device and can effectively buffer when a part falls so as to prevent the part from being damaged when the part falls too fast. A transmission mechanism is installed on the right end in the auxiliary blanking device, an independent motor is installedin the transmission mechanism, after a motor drives a sprocket wheel to be transmitted, a tooth rod can be used for driving a bottom abnormal-shaped gear to rotate, and then, the abnormal-shaped gearcan open a closing cover t
