Description

Technical Field

[0001] The utility model relates to the technical field of inner tube mold maintenance, in particular to a maintenance and fixing device for an inner tube mold. Background Art

[0002] At present, the inner tube is commonly known as the inner tube, which refers to a circular elastic tube with a tire valve used to maintain the internal pressure of the tire. The valve is used to inflate and keep the air at a certain pressure in the inner tube. The inner tube should have good air tightness, heat resistance, elasticity, aging resistance and small permanent deformation, and is generally made of butyl rubber.

[0003] During the production process of the inner tube, the rubber sheet is placed in a preheated mold and pressed by a press. After pressing, the rubber sheet in the mold is taken out, cut into circles by a shearing machine, and two circular rubber sheets are stacked together to form the basic shape of the inner tube. Then, the stacked rubber sheets are pressed again with a mold to make them tighter and meet the design requirements. Finally, after cooling treatment, the inner tube molding process is completed.

[0004] The inner tube mold is often damaged after long-term use. In order to save costs, the inner tube mold is repaired. For this reason, a new technical solution needs to be designed to solve the problem, so that the inner tube mold can be fixed quickly and labor-savingly. Utility Model Content
