Multifunctional testing fixture for die-casting product quality inspection

The invention is suitable for the technical field of die casting quality inspection equipment, and provides a multifunctional inspection tool for die casting product quality inspection, which comprises a base, a support frame, an inspection seat, a pressure sensor, an inflation mechanism and a limiting mechanism. By arranging the limiting mechanism, the purpose of conveniently replacing the die casting can be achieved, the die casting is placed on a sealing rubber ring, and at the moment, through mutual cooperation of a lifting assembly, an electric push rod, a sealing pressing plate, a sealing air bag and an air outlet pipe, the die casting can be sealed and limited at the same time; then air tightness detection can be conducted on the die casting through mutual cooperation of an air conveying pipe, a pressure sensor and the parts, reverse operation is conducted on the operation after detection, at the moment, the die casting is driven by the sealing air bag to ascend, and meanwhile the die casting and the s
