Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a molding mold for producing bicycle inner tubes. Background Technology

[0002] Bicycle inner tube production refers to the process of processing rubber materials into inner tubes that meet specifications, fit inside the bicycle tire cavity, and possess a certain degree of airtightness through a series of processing techniques. The inner tube is one of the key components of the bicycle tire system, responsible for bearing the rider's weight, maintaining the tire's shape, and ensuring a proper fit with the tire.

[0003] Currently, in the production of bicycle inner tubes, the inner tube needs to be shaped inside a mold. However, waiting for the material to be shaped after injection may result in uneven material distribution inside the mold. Since the molds for producing bicycle inner tubes usually need to be customized and adjusted according to different models, sizes, or product specifications, the changeover time is currently long and quick changes are not possible, which reduces work efficiency.
