Description
Technical Field
[0001] This utility model relates to the field of liquid silicone processing technology, and in particular to a cleaning device for liquid silicone injection pipes. Background Technology
[0002] Liquid silicone rubber (LSR) is a two-component, thermosetting material. Due to its excellent biocompatibility, high and low temperature resistance, insulation, transparency, and mechanical properties, it is widely used in high-end fields such as medical devices, baby products, automotive seals, electronic packaging, and kitchenware. In the liquid silicone injection molding process, the base rubber and curing agent are precisely proportioned by a metering pump, thoroughly mixed by a static mixer, and then injected into the high-temperature mold cavity through a dedicated injection pipe (also known as a nozzle or runner) for vulcanization and shaping. The disassembly, cleaning, reinstallation, and debugging processes are time-consuming and seriously affect equipment utilization and production efficiency. For complex structures or long pipes, it is difficult to ensure that all residues are completely removed manually. The residual trace amounts of cured rubber particles can become a source of contamination for the next production, leading to product defects. Therefore, we designed a cleaning device for liquid silicone injection pipes. Utility Model Content
