Problems solved by technology
Compared with the traditional metal high-speed iron curved beam, the flame-retardant high-strength high-speed iron curved beam is integrally formed with 3D nylon air duct, which does not require complex processes such as opening, bending, and welding, and the contour shape of the formed product has been uniformly standardized (mold guarantee). Products that are purely hand-molded with metal openings, bending, and welding have different contour shapes

Embodiment Construction
[0041] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0042] A molding process of a 3D nylon air duct forming a flame-retardant curved beam, the forming process of the 3D nylon air duct forming a flame-retardant curved beam includes the following steps:
[0043] Step 1: Make 3D nylon air duct; cut the nylon air duct with a width of 300-500mm into the prototype air duct with the shape and size of the inner cavity of the curved beam to be produced, and then use the sealing machine to seal the periphery of the prototype air duct, leaving The air outlet mouth, thus forming a 3D nylon air duct;
[0044] Step 2: Material selection of flame retardant carbon fiber pre-dye impregnation material; the material pre-impregnated with epoxy flame retardant resin and carbon fiber precursor is called flame retardant carbon fiber prepreg;
[0045] Step 3: L...

Abstract
The invention relates to a molding process and a mold for forming a 3D nylon air duct to form a flame-retardant curved beam. The forming process for forming a 3D nylon air duct to form a flame-retardant curved beam includes the following steps: Step 1: making a 3D nylon air duct; Step 2: resisting Material selection for carbon fiber pre-dyeing impregnation; Step 3: Lamination and pre-forming of prepreg; Step 4: Curing and molding of composite materials. The production mold includes: upper mold, lower mold, slider, air nozzle device port, the air nozzle device port is located on the lower mold, and the slider includes two pieces; the air nozzle device port is placed with a 3D nylon air duct nozzle; the lower mold is placed as a product As a benchmark, place two sliders on the left and right sides of the lower mold, and then cover the upper mold on the lower mold and the two sliders to fix the mold to form the flame-retardant curved beam. The flame-retardant high-strength high-speed iron curved beam integrally formed with 3D nylon air duct also achieves the flame-retardant effect compared with the traditional metal-formed curved beam, and is easy to operate, flexible in product shape, higher in strength, lighter in weight, and corrosion-resistant.
Description
technical field [0001] The invention relates to a molding process and a production mold, in particular to a molding process and a production mold for forming a flame-retardant curved beam of a 3D nylon air duct. Background technique [0002] Compared with traditional metal materials, carbon fiber composite materials have many excellent properties, such as light weight, high specific strength, good dimensional stability, and excellent chemical stability. Therefore, its application range is wider and its manufacturing process is becoming more mature. According to the final use and structure of the product, many carbon fiber composite molding processes have emerged. Compared with the traditional metal high-speed iron curved beam, the flame-retardant high-strength high-speed iron curved beam is integrally formed with 3D nylon air duct, which does not require complex processes such as opening, bending, and welding, and the contour shape of the formed product has been uniformly st...
