Description

Technical Field

[0001] This utility model relates to the field of silicone molding machine technology, and in particular to a feeding device for a liquid silicone injection molding machine. Background Technology

[0002] Liquid silicone rubber (LSR) is a non-toxic, odorless, and environmentally friendly elastomer material with excellent physiological inertness, resistance to high and low temperatures, aging resistance, and high transparency. It is widely used in medical devices (such as respirators, catheters, and pacifiers), baby products, automotive seals, electronic packaging, and kitchenware. Liquid silicone injection molding technology is a highly efficient process that involves precisely metering and mixing two-component liquid silicone at low temperatures, then injecting it into a heated mold for rapid vulcanization and shaping. Traditional gear pumps or single-screw pumps are prone to uneven feeding due to pressure fluctuations when conveying high-viscosity liquid silicone. Especially when the liquid level in the tank is low, the pump is prone to drawing in air, causing "dry running" or "cavitation," resulting in inaccurate metering in the injection molding machine. This leads to quality defects such as insufficient material, unstable weight, dimensional deviations, or air bubbles in the product. Therefore, we have redesigned a feeding device for a liquid silicone injection molding machine. Utility Model Content
