Description

Technical Field

[0001] This utility model belongs to the field of liquid injection molding, and in particular relates to an automated device for embedding and removing injection-molded LSR products. Background Technology

[0002] Liquid silicone rubber (LSR) molding, sometimes called liquid injection molding (LIM), is a thermosetting process that mixes two compounds and then heat-cures them in a mold using a platinum catalyst to create flexible silicone parts. Flexible silicone parts often contain inserts such as metal, glass, wood, fiber, paper, rubber, or pre-molded plastic parts, with metal being the most common insert. Insert molding is a process where an insert is pre-fixed in a suitable position in an injection mold before plastic is injected. After the mold opens, the insert is encased in the cooled and solidified plastic, resulting in a molded product with inserts such as threads or electrodes. Currently, inserts need to be manually placed, which significantly increases the injection molding cycle time. Utility Model Content
