Problems solved by technology

When a large amount of filler is added, the viscosity of the castable will increase significantly, making it difficult to inject and fill the mold smoothly, the pouring effect is not good, and the cured product is prone to defects such as bubbles, which seriously affects product performance
In addition, the pouring mold is designed to focus on molding and lacks consideration of the process, making it difficult to control the product defect rate

Abstract

The invention discloses an epoxy resin composite material pouring mold. The pouring mold is a hollow cavity with a pouring opening, an air hole penetrates through one side of the hollow cavity, an air guide pipe penetrates through the air hole, and an air valve is connected with the air guide pipe to connect and disconnect the air guide pipe. The vacuum pump is connected with the air guide pipe so as to exhaust air from the hollow cavity.

Description

technical field [0001] The invention relates to the technical field of molds for epoxy resin composite materials, in particular to a casting mold for epoxy resin composite materials. Background technique [0002] Epoxy resin composite material is a composite functional material made of epoxy resin and insulating filler. Due to its excellent dielectric properties, good stability and many other advantages, it not only plays an important role in the electrical industry, but also has a wide range of applications in various fields such as medicine, aerospace, civil engineering, rail vehicles, and electronic integrated products. [0003] In order to ensure the excellent performance of epoxy resin composite materials, on the one hand, it depends on the formulation design and filler selection, and on the other hand, it is closely related to the casting and curing process. In the casting and curing process, the casting mold is indispensable. When a large amount of filler is added, ...
