Description

Technical Field

[0001] This utility model specifically relates to a multi-station shoe sole injection molding machine. Background Technology

[0002] Currently, shoe soles are a crucial component of footwear, and the materials used for soles are diverse, categorized into natural and synthetic materials. Natural materials include natural leather, bamboo, and wood, while synthetic materials include rubber, plastics, rubber-plastic composites, recycled leather, and flexible cardboard. Currently, the production of rubber shoe soles involves injecting molten material into a shoe sole mold using an injection molding machine. Most existing injection molding machines are fixed in place. During operation, the process is cumbersome because the injection molding of shoe soles takes time, and after molding, the sole must be manually or with tools removed from the mold to accommodate new material. This process stops the injection molding machine, preventing it from moving to other locations to inject into multiple molds simultaneously. The operation is inconvenient, and the efficiency needs improvement. Therefore, there is an urgent need to develop a multi-station rubber shoe sole injection molding mechanism that is simple to operate, has a sophisticated structure, and high work efficiency.
