The utility model discloses flat vacuum cup forming equipment convenient to fix, and relates to the technical field of vacuum cup production. According to the flat vacuum cup forming equipment convenient to fix, by arranging the fixing frame, the fixing blocks, the clamping holes, the clamping blocks, springs, fixing plates, bolts, fixing bases and a long
pipe, the function of fixing the long
pipe is achieved, the long
pipe is prevented from moving in the water swelling process, and therefore a round pipe expands according to a preset shape under the uniform pressure environment; the size precision and the shape consistency of the flat vacuum cup can be improved, and the defective rate of products is reduced; by arranging the fixing base, the connecting rod, the connecting frame, the fixing rod, the connecting ring, the electric telescopic rod, the first adjusting rod, the clamping block and the manufactured long pipe, the function of multiple fixing of the manufactured long pipe is achieved, the fixing function of the manufactured long pipe is further enhanced, and the stable fixing mode can prevent the manufactured long pipe from accidentally moving or popping out in the high-pressure water expansion process.
