Description

Automatic heating core mold structure

Technical Field

The utility model relates to an insulator sleeve pipe manufacture equipment field, in particular to automatic core mould structure of heating.

Background

The composite hollow insulator has wide application in the field of high-voltage power transmission and transformation, such as circuit breakers, transformers, switch equipment and the like. The insulator generally comprises an insulating sleeve made of glass fibers impregnated with epoxy resin and a silicon rubber umbrella skirt arranged outside the insulating sleeve, wherein the glass fibers impregnated with the epoxy resin are wound on a core mold in the production process of the insulating sleeve to finally form the insulating sleeve, and the core mold needs to be heated when in use. In the prior art, the core mold is usually placed in the heating chamber for heating, and in such a way, a set of bulky heating chamber needs to be built for heating the core mold, which results in higher production cost. In view of this, the utility model people of this application obtain an automatic core mould structure of heating through intensive research.
