AI Technical Summary

Technical Problem

In the preparation of high-pressure insulators, the prior art has problems of uneven material distribution and mold release stress cracking, especially in high-profile umbrella skirts, the rotary mold method has high cost and insufficient stability, so it is impossible to effectively solve the cracking problem.

Method used

A multi-slider integrated mold is used to achieve uniform distribution of materials and self-repair and self-repair during mold release by axial and radial pressing, combined with a self-repairing hot pressing device, and the inner conical porous structure and self-repair capsule are used to achieve uniform distribution of materials and self-repair during mold release to avoid cracking.

Benefits of technology

It improves the density uniformity and durability of high-voltage insulators, avoids cracking problems during mold release, extends the service life of the side slider, and reduces equipment cost and operation complexity.

Abstract

The present invention discloses a collaborative pressurizing structure, a self-repairing hot pressing device and a high-voltage insulator forming process, comprising a frame and a control mechanism, and also comprising an equipment main body installed in the inner cavity of the frame, a hot pressing mold installed in the inner cavity of the frame, a side slider comprising a slider main body and an inner conical surface arranged at one end of the slider main body, the inner conical surface being provided with a self-repairing component, four groups of auxiliary linkage mechanisms installed around the equipment main body, a main linkage mechanism installed at the bottom of the inner cavity of the frame, and a distance adjustment component installed at the top of the frame, for driving the upper slider to reciprocate along the axial direction of the mold sleeve. The present invention solves the problems of V-shaped umbrella edge and deep-edge umbrella skirt forming and demolding in one-piece molding by arranging a multi-slider mold, axially pressurizing the lower slider and the upper slider, and cooperating with the radial pressurizing of the side slider, thereby improving the overall uniformity and durability of the high-voltage insulator, and avoiding the problem of weak bonding between the umbrella skirt and the columnar bonding surface in step-by-step molding.
