Forming mold and forming method for composite material tubular parts with flanges

Abstract

The invention discloses a forming mold for composite material tubular parts with flanges. The forming mold for the composite material tubular parts with the flanges comprises a first combined mold anda second combined mold; the first combined mold is provided with a first pipe cavity and a first annular cavity; the first pipe cavity and the first annular cavity communicate with each other at theposition of a pipe port in one end of the first pipe cavity; the second combined mold is provided with a second pipe cavity and a second annular cavity; the second pipe cavity and the second annular cavity communicate with each other at the position of a pipe port in one end of the second pipe cavity; the first combined mold and the second combined mold are subjected to mold closing, and the firstannular cavity is made to communicate with the second annular cavity; and a forming method for using the forming mold to machine the composite material tubular parts with the flanges is disclosed. The forming mold has the beneficial effects that by performing combined design on the forming mold, in the forming process of the composite material tubular parts with the flanges, paving and pasting ofprepreg can be easier and faster, and operation is convenient; after curing molding of the tubular parts, demolding of the forming mold can be achieved easily, and operation is easy and convenient; and the production efficiency is improved, and practicability is high.

Description

technical field [0001] The invention relates to a molding die and a molding method of a composite material part, in particular to a molding mold and a molding method of a composite material tubular part with a flange. Background technique [0002] In the molding of composite materials, the existing overall mold forming method cannot realize the molding of composite tubular parts with flanges, and the overall mold forming method cannot realize the prepreg laying of composite tubular parts with flanges, making the molding The process is very difficult. Even if the paving is completed, it is very difficult to demould the molded product. It is difficult to demould after molding regardless of whether the integral mold of the female mold or the integral mold of the male mold is used. In addition, the integral mold forming method is also difficult. It is difficult to realize integral molding of the flange part and the tubular part. Contents of the invention [0003] Purpose of t...
