Description

Forming die for rubber tube production Technical Field The embodiment of the disclosure relates to the technical field of rubber tube processing, in particular to a molding die for rubber tube production. Background The rubber tube is used as a tubular product widely applied to various fields, the performance of a manufacturing process and a forming die plays a key role in product quality and production efficiency, and in various industries such as industry, automobiles, medical treatment and the like, the rubber tube is used for conveying various fluid media such as chemicals in industrial production, cooling liquid and fuel oil of automobile engines, medical liquid in medical equipment and the like, and the requirements of different industries on the specification, performance and quality of the rubber tube are different. The traditional rubber tube forming process has a plurality of limitations, for continuous rubber tubes, extrusion equipment is often adopted for forming, however, for special-shaped rubber tubes, rubber tubes at connecting positions or rubber tubes with larger sizes, the method is difficult to be applied, at the moment, the method is mostly adopted for injection molding or compression molding, in a common mold forming mode, an upper mold closing structure and a lower mold closing structure are common, an inner cavity of the rubber tube is built by arranging mold cores in the upper mold and the lower mold, for straight-tube rubber tubes, the demolding is relatively easy, and the drawing mode can be adopted for core stripping; however, for bent pipes, particularly rubber pipes with irregular inner cavities, the release of the inner core cannot be realized at all by simple linear core pulling, so that the equipment cost and the operation difficulty are increased, the rubber pipes are easily damaged in the demolding process, and the product quality is affected. When the rubber pipes with obvious difference of inner diameters of inner cavities are involved, for example, rubber pipes for some connection joints, the end parts of the rubber pipes need to form convex shapes or concave shapes with different inner diameters, the traditional inner core injection molding mode faces great challenges, the inner cores with corresponding shapes can be clamped at molding positions after molding due to the structural characteristics of the convex shapes and the concave shapes, the clamping problem cannot be solved in either drawing or rotating demolding modes, the rubber pipes with different inner diameters along the axial direction are difficult to be molded directly at one time, and the diversified design and production of rubber pipe products are greatly limited. In the feeding link, the prior art has defects as well, part of forming dies adopt fixed structure feeding, so that the pulling-out force of a rubber tube is insufficient during demolding, the production efficiency and the product quality are affected, some traditional rubber tube forming dies are inconvenient to operate in the processes of closing and opening the mold, the forming speed is reduced, the overall production efficiency is further affected, when the low-pressure rubber tube is vulcanized and formed, the end face incision of the rubber tube is manufactured, the end face incision of the rubber tube is often required to be punched by a punching cutter after the vulcanization and the forming process is undoubtedly increased, the time consumption of the whole processing process is prolonged, the labor is wasted, and the processing efficiency is low. In the temperature control and shaping links in the rubber tube shaping process, the prior art is not satisfactory, and part of dies are in the shaping process, because the heating mode and the temperature control on raw materials are not accurate enough, the thermoplastic shaping conditions of rubber tubes with different specifications and materials cannot be met, the rubber tube shaping quality is unstable, the rejection rate is higher, in the aspect of rubber tube shaping, the inner diameter and outer diameter size precision and the shape accuracy of the rubber tube are difficult to ensure by the traditional dies, and especially, the limitation of the traditional dies is more remarkable for some application scenes with extremely high requirements on the size precision, such as the fields of aerospace, precise instruments and the like. In summary, the existing rubber tube forming mold has many defects in structural design, feeding mode, demolding operation, temperature control, shaping precision and the like, and is difficult to meet the increasing production demands of diversified and high-precision rubber tubes, and a novel rubber tube forming mold is developed to solve the technical problems, improve the production efficiency and quality of the rubber tubes and become a problem to be solved urgently in the industry.
