Problems solved by technology

However, there are currently four mature application forms of carbon fiber. One is the hand lay-up method, in which the carbon fiber sheets impregnated with glue are cut into layers, or resin is applied while layering, and then hot-pressed. , the strength of the carbon fiber product made by this method is high, but the production efficiency is low; one is the winding molding method, which winds the carbon fiber monofilament on the carbon fiber shaft, this method is only suitable for making cylinders and hollow vessels, and the production efficiency Low; one is the molding method, which is to put the pre-impregnated carbon fiber material into the metal mold, pressurize the excess glue to overflow, and then cure it at high temperature. The carbon fiber products made by this method The strength is high, but the production efficiency is also low, and structural parts cannot be made; one is the long-fiber pellet injection molding method, which pre-processes carbon fibers to make pellets, and then injection molding through an injection molding machine. Although this method solves the problem of production efficiency Howev

Abstract

The invention discloses a carbon fiber forming device which comprises a distributing and mixing structure, a storage and transmission converting structure and a multi-stage injection structure. An injection spray nozzle is arranged on the injection structure. The storage and transmission converting structure comprises a storage and transmission converting structure body for achieving the storage and transmission converting function for received injection molding melt. The distributing and mixing structure comprises a distributing and mixing structure body for shearing and melting a to-be-machined material. The multi-stage injection structure is used for completing the injection process of the injection molding melt. The requirement for efficiency of industrial mass production can be achieved, the requirement for strength of a carbon fiber finished product can also be met, the tensile strength and anti-impact strength of the injection molding finished product are both greatly improved compared with those of the continuous fiber heating production mode long in shearing time.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a carbon fiber molding equipment. Background technique [0002] Carbon fiber is a new type of inorganic fiber material with a carbon content above 90% (mass fraction), with high specific strength, high specific modulus, high temperature resistance, corrosion resistance, fatigue resistance, radiation resistance, electrical conductivity, heat transfer, and relative density A series of excellent properties, such as small, are typical high-performance fibers. Carbon fiber not only has the inherent characteristics of carbon materials, but also has the softness and processability of textile fibers. The components made of carbon fibers are light in weight, high in specific stiffness, and have a wide range of applications. However, there are currently four mature application forms of carbon fiber. One is the hand lay-up method, in which the carbon fiber sheets impregnated with ...
