Carbon fiber product forming mold and forming method

Abstract

The invention provides a carbon fiber product forming mold and method. The carbon fiber product forming mold comprises an upper mold, a lower mold, multiple heating pipes and silica gel pieces; the silica gel pieces are bonded on the inner side wall of the upper mold or the lower mold; the upper mold and the lower mold are matched in size, and are closed to form a forming cavity for forming carbonfiber prepreg preformed bodies; multiple through holes parallel to the inner side walls are arranged on the upper mold and the lower mold in a penetrating mode; the multiple through holes are distributed at equal intervals, and the distances between the adjacent inner side walls are the same; and the multiple heating pipes are correspondingly arranged in the multiple through holes one to one. Thecarbon fiber product forming mold has the following beneficial effects: the carbon fiber prepreg preformed bodies are suffered from uniform and stable pressure to improve the pinhole defects on the surfaces of carbon fiber products.

Description

technical field [0001] The invention relates to the technical field of forming molds, in particular to a carbon fiber product forming mold and a forming method. Background technique [0002] At present, the molds for the molding process of carbon fiber prepreg are designed as upper and lower steel mold structures. The carbon fiber prepreg is placed in the middle of the upper and lower mold cavities. The upper and lower molds are pressed together to provide pressure for the carbon fiber prepreg, and at the same time, the carbon fiber prepreg is passed through the mold. The material is heated, and after a period of time of heat preservation and pressure, the mold is opened and the product is taken out. [0003] At present, the carbon fiber composite prepreg molding process has become the preferred process for mass production of carbon fiber prepreg due to its high performance, stability, fast production cycle, low mold investment, and moderate cost. The pinhole defects on the...

[0003] At present, the carbon fiber composite prepreg molding process has become the preferred process for mass production of carbon fiber prepreg due to its high performance, stability, fast production cycle, low mold investment, and moderate cost. The pinhole defects on the surface of the parts are more obvious, which makes the subsequent coating more difficult and costly, so it is necessary to solve the pinhole defects on the surface of the parts
