Abstract

The invention discloses a composite material mould with a reinforcing structure and a preparation method thereof. The composite material mould with the reinforcing structure comprises a mould casing, wherein a criss-cross #-shaped reinforcing structure is arranged on the mould casing, and is provided with a foam core material; a plurality layers of glass fiber reinforced plastics formed by uniaxial glass fiber cloth are laid on the surface of the foam core material; as the criss-cross #-shaped reinforcing structure is additionally attached onto the mould casing, the composite material mould has the benefits that the mould casing is not subjected to bending deformation, and the stability performance of the mould casing is improved; in addition, the criss-cross #-shaped reinforcing structure is adopted to enable various vertical and horizontal components to be mutually controlled and supported, so that the performance of the mould is enabled to be reasonably controlled; the foam core material has no strength, and plays a role in supporting the reinforcing structure; a plurality layers of glass fiber reinforced plastics formed by uniaxial glass fiber cloth are laid on the surface of the foam core material.

Description

technical field [0001] The invention relates to a composite material mold, in particular to a composite material mold with a reinforced structure and a preparation method thereof. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. In short, a mold is a tool used to shape an article. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] At present, according to the existing materials and equipment, it is impossible to directly produce the composite material female mold in one step. Based on the current production process of the female mold, the female mold is made through the male mold, so the male mold...
