[0001] The application relates to the technical field of part processing, in particular to a cloth-clamped rubber pipe forming die. BACKGROUND

[0002] As a key industrial component, the cloth-clamped rubber pipe is widely used in many industries such as chemical industry, petroleum, pharmacy, food, aerospace and the like, and the market demand for the cloth-clamped rubber pipe is steadily increasing. In actual application scenarios, the cloth-clamped rubber pipe can well solve the problem that a metal pipe cannot be normally installed and used under special working conditions due to its unique performance advantages such as pressure resistance, high-temperature resistance, corrosion resistance and fatigue resistance.

[0003] At present, the cloth-clamped rubber pipe is formed by using materials such as ethylene-propylene-diene rubber and chloroprene rubber through a manual brushing or pasting process and then vulcanized by using a vulcanization tank. However, the manual brushing method has long production time and low production efficiency, and the product quality is greatly affected by human factors, so that effective standardization control is difficult to implement, and problems such as inconsistent thickness of each part of the formed cloth-clamped rubber pipe, damage during demolding, and insufficient tightness between the rubber and the cloth during vulcanization are easily caused, so that the cloth-clamped rubber pipe produced has problems such as low temperature resistance and poor pressure bearing capacity.

[0004] Therefore, it is necessary to provide a new technical solution to improve one or more problems in the above solution. CONTENT OF THE INVENTION
