Description

Technical Field

[0001] This utility model relates to the field of reaction injection pultrusion molding, and in particular to a casting and mixing device. Background Technology

[0002] Reaction injection pultrusion is a technology that uses low-viscosity resin monomers or oligomers to impregnate fibers and react and polymerize them in a pultrusion mold to form composite material products. The shape of the product is shaped by the cavity of the pultrusion mold. Typically, a mold cavity requires a set of material injection equipment, including a metering pump, delivery pipe, mixing device for different resin components, and injection gun head.

[0003] To increase the output of composite material products, it is necessary to add resin injection equipment. The addition of resin injection equipment leads to high equipment investment and increases the investment in factory buildings due to the large footprint of the equipment. In addition, the mixing of materials is done by inserting a static mixing core into a round tube, which makes cleaning very difficult after blockage. Utility Model Content
