AI Technical Summary

Technical Problem

In the installation process of existing aluminum profile extrusion dies, the bolt connection point is the only rigid support area, resulting in a single stress point and potential for insufficient installation stability.

Method used

The system employs an interlocking mechanism, which uses the interlocking of the interlocking pieces and the thermal expansion pieces to achieve dynamic self-locking by utilizing the difference in thermal expansion coefficients. This eliminates single-point stress concentration, and the interlocking pieces and slots form an interference fit. Combined with the rectangular plate structure and stepped fastening, this enhances the stability of the mold.

Benefits of technology

It improves the overall stability and connection strength of the mold, avoids stress concentration, enhances the convenience of assembly and disassembly, and extends the service life of the mold.

Abstract

The utility model discloses a thin-wall multi-cavity building profile extrusion die, and relates to the field of extrusion dies. The mold comprises a divergent mold body and a forming mold body, the divergent mold body and the forming mold body are fixed in an inserted connection mode through an inserted connection mechanism, the inserted connection mechanism comprises a plurality of inserted connection pieces, the inserted connection pieces are fixedly connected with the divergent mold body, and thermal expansion pieces are fixedly clamped on the inner sides of the inserted connection pieces. A plurality of inserting pieces in the inserting mechanism are fixedly connected with the divergent die, thermal expansion pieces are clamped on the inner sides of the inserting pieces, self-locking is achieved in the extrusion and temperature rise process by means of the characteristic that the thermal expansion coefficient of the thermal expansion pieces is higher than that of other components, and by means of the thermal expansion fixing mode, the connection stability of the die is improved, and the die can be conveniently assembled and disassembled. And the pressure is effectively dispersed, and the condition of stress concentration is avoided.
