AI Technical Summary

⚠Technical Problem

In the molding process of composite material compartments, traditional methods are difficult to guarantee the stiffness and strength of the structure, and it is also difficult to control the continuity of the fibers, resulting in poor molding quality, especially posing safety hazards when used in high stress environments.

⚗Method used

The composite material compartment molding die, which adopts longitudinal ring reinforcement, includes components such as core mold, segmented male mold, outer female mold, and mouth frame pressing fixture. By setting reinforcing ring grooves and positioning pins in the die, the continuity of fibers and the rigidity of the die are ensured. The features are processed by direct molding method to avoid damage caused by machining.

🎯Benefits of technology

It improves molding quality and structural rigidity, ensures fiber continuity, reduces molding difficulty and cost, and improves dimensional accuracy and surface condition.

Abstract

The application provides a longitudinal ring band reinforced form composite cabin section forming die and a forming method thereof, which comprises a core die, a split male die, an outer female die, a mouth frame pressing tool, an upper end frame pressing ring, a lower end frame pressing ring and a base. The core die is arranged in the center of the forming die and fixed on the base. The split male die is wrapped on the outer wall of the core die. A reinforcing ring groove is arranged on the split male die along the longitudinal direction and the circumferential direction. The mouth frame pressing tool is arranged on the outer side of the split male die. The upper end frame pressing ring is horizontally fixed on the upper end surface of the core die. The lower end frame pressing ring is horizontally fixed on the bottom surface of the core die. The outer female die is wrapped on the outer wall of the split male die. The cabin section has the consistency of the overall performance and quality, and the structure has high dimensional position precision, better surface state and good rigidity and bearing capacity.
