The utility model provides a cloth clamping oil seal, a preformed framework of the cloth clamping oil seal, a framework and a framework mold. A preformed framework of the cloth clamping oil seal is formed by folding long-strip-shaped and sheet-shaped dipping clamping weaving fibers and comprises N dipping clamping weaving sections which are equal in length and sequentially connected in the length direction, and N is an even number larger than or equal to 4. The impregnated interwoven fibers are stacked in a winding mode to form a convolute structure and are folded towards the outer side of the convolute structure in the width direction of the impregnated interwoven fibers to form a multi-layer stacked structure. And the preformed framework is molded by a framework mold to form the framework. And preparing a rubber body on the inner side of the framework to obtain the cloth-sandwiched oil seal. The convolute structure enables the thickness of each part of the skeleton to be uniform; the two free ends of the im
