AI Technical Summary
Existing carbon fiber strip molding dies have problems such as the need for subsequent machining at corners, high operational difficulty, difficulty in demolding, unsatisfactory handling of excess glue, and inaccurate positioning during the molding process, which affect product quality and production efficiency.
A mold structure including a lower mold and an upper mold was designed. The lower mold has a slider, a demolding wedge and an overflow groove, while the upper mold has a trapezoidal groove and a recess. The slider is engaged with the trapezoidal groove. The design of the slider enables the flat laying and positioning of the carbon fiber strip. The overflow groove discharges excess resin, and the demolding wedge and recess assist in demolding.
It enables the carbon fiber strip corners to be formed into sharp corners in one step, reducing subsequent processing costs, preventing fiber cloth wrinkles, ensuring product dimensional accuracy and integrity, simplifying the demolding process, and reducing the production cycle.
