Manufacturing method of carbon fiber composite material part mold

Abstract

The invention relates to a manufacturing method of a carbon fiber composite material part mold, belongs to the field of mold manufacture and mainly aims at the problems of complicated manufacturing process, high cost and short service life of an existing carbon fiber composite material structure part. The manufacturing method comprises the following steps: manufacturing a foam model according to a part digifax, then manufacturing a surface part and a supporting part of the mold and finally bonding the surface part and the supporting part of the manufactured mold together through a resin material to obtain the mold. According to the manufacturing method provided by the invention, due to the adoption of a three-dimensional integrated coating technology, a mold forming surface material is free from lapping defects, and the part quality is improved; the mold takes the resin material as a main body, and steel is replaced, so that the light weight is realized, the mold surface processing efficiency is improved by more than 3 times, the manufacturing period is shortened, and the overall manufacturing cost is reduced by more than 20 percent.

Description

technical field [0001] The invention relates to a method for manufacturing a carbon fiber composite part mold, which belongs to the field of mold manufacturing. Background technique [0002] Carbon fiber composite material is a new type of industrial composite material. Its strength and modulus are 7.2 times and 6.4 times that of iron, respectively, and its specific gravity is only a quarter of that of iron. And it has good wear resistance, high temperature resistance and fatigue resistance. At present, there are two commonly used methods for forming carbon fiber composite structural parts: one is autoclave forming technology. This molding technology is applied to molds with large volume, simple structure and low manufacturing requirements. The molds manufactured by this method generally need to be machined to meet the precision requirements. Another method is compression molding technology. It is formed by pressing a metal mold. The formed mold can meet the precision re...

AI Technical Summary

Problems solved by technology

[0004] (1) The manufacturing process is complicated: First, the material of the mold itself is a composite material, which makes the process of mold forming and manufacturing have certain complexity and unknowability, and different processes can sometimes cause large differences in product quality

Second, the mold is bulky and cumbersome, and cannot be lightweighted, which adds great difficulty to the manufacturing process

Third, the surface hardness of the composite material is low, and it is easy to be damaged if bumped during the mold manufacturing process

[0005] (2) Long manufacturing cycle: Composite molds are difficult to manufacture and require a lot of time to complete

[0006] (3) High manufacturing cost: complex manufacturing process and high price of raw materials increase the manufacturing cost of composite molds

[0007] (4) Lower service life: Compared with metal molds, molds made of composite materials have lower life and are prone to damage
