Demolding tool for small-caliber water-soluble core mold

Abstract

The invention belongs to the technical field of machining, and relates to a demolding tool designed for a water-soluble core mold demolding procedure in a carbon fiber composite material forming process for integrally forming a closed cavity. The demolding tool comprises a differential mechanism, a demolding drill bit mechanism, a water injection mechanism and a conveying mechanism, and the differential mechanism drives the demolding drill bit mechanism and the conveying mechanism to rotate at the same time, so that functions of trepanning, expanding, sand scraping, sand cleaning and the like are achieved. The water injection mechanism injects water into the water-soluble core mold, the sand melting function is achieved, and the phenomena that the local strength of a carbon fiber part is affected due to the fact that the diameter of a demolding process hole is too large, and the water-soluble core mold in the closed cavity is difficult to clean and low in efficiency due to the fact that the diameter of the demolding process hole is too small are avoided; and the demolding efficiency of the water-soluble core mold based on the small-caliber demolding process hole is improved, meanwhile, multifunctional demolding operation integrating trepanning, water injection and sand melting, sand scraping and sand cleaning is achieved, and large-area demolding operation can be achieved through the small-caliber process hole.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a demoulding tool for a water-soluble mandrel in a carbon fiber composite material molding process for integral molding of a closed cavity. Background technique [0002] For integrally formed carbon fiber composite products, the water-soluble mandrel inside the closed cavity needs to be removed after molding. When removing the water-soluble mandrel, it is necessary to open a demoulding process hole at an appropriate position on the carbon fiber body, and soak the water-soluble mandrel through the process hole. The water-soluble mandrel will change from hard and dense to soft after contacting water, so that the mandrel can be removed by artificial mechanical force. Take it out after breaking it down. If the diameter of the demoulding process hole is too large, it will affect the local strength of the carbon fiber part. If the diameter of the demoulding process hol...

AI Technical Summary

Problems solved by technology

If the diameter of the demoulding process hole is too large, it will affect the local strength of the carbon fiber part. If the diameter of the demoulding process hole is too small, it will be difficult to clean the water-soluble mandrel inside the closed cavity, and the efficiency will be low.
