A manufacturing method for integral molding of lightweight carbon fiber chassis

Abstract

The invention discloses a manufacturing method for the integral molding of a lightweight carbon fiber chassis, comprising the following contents: preforming guide rails and wedge-shaped parts; realizing threaded mounting holes; realizing threaded mounting holes through metal embedded parts, on the metal embedded parts Pre-processing the installation bottom hole, using the pre-processing installation bottom hole to accurately position on the molding surface of the cabinet mold; pre-forming the side mounting beam; cabinet layering; machining; surface metallization on the internal and external surfaces; surface three-proof. The present invention conducts reasonable split design, preforms guide rails, wedge-shaped parts, and side connecting beams, and then assembles them with box molds to carry out overall box laying and autoclave co-curing molding, which not only reduces manufacturing difficulty, but also ensures The overall rigidity requirements of the box body; more printed board components need to be installed inside the box body, power supply components need to be installed outside the box body, there are many installation interfaces, and the location is compact. Through the precise positioning technology of embedded parts, the high precision requirements of the installation position size are realized. , to ensure the connection strength.

Description

technical field [0001] The invention relates to a manufacturing method for integral molding of a chassis, in particular to a manufacturing method for integral molding of a lightweight carbon fiber chassis. Background technique [0002] The publication number is CN 105856756A, which discloses a carbon fiber composite box and its preparation method. The box in this invention has a simple structure, no connection position and assembly requirements, and is similar to a turnover box for outdoor use; this invention uses resin The import method, the material is carbon fiber and resin; the molding method is an improved method of hand lay-up molding, the performance is not high, the cost is low, and it is widely used in civilian use for parts that do not require high size and mechanical properties.
