Molding process of PE-RT pipeline

Abstract

The invention relates to a molding process of a PE-RT pipeline. The process comprises a PE-RT pipe extrusion molding process and a joint injection molding process on the PE-RT pipe, wherein the PE-RT pipe extrusion molding process comprises the following steps of: preparing materials; performing extrusion molding on the PE-RT pipeline by using an extrusion machine; sizing in vacuum; performing traction and conveying; cutting the PE-RT pipeline into a predetermined size and entering a location area. The joint injection molding process on the PE-RT pipeline comprises the steps: locating, namely, enabling a core of a rotating mechanism positioned on a rotary disc to penetrate through the PE-RT pipeline; pre-heating of a joint area, namely, driving the PE-RT pipeline to rotate to a hot air mechanism by virtue of a rotating mechanism, and melting the PE-RT pipeline joint area to a high-elastic state by virtue of the hot air mechanism; injection molding of the joint, namely, driving the PE-RT pipeline to rotate to an injection mould by virtue of the rotating mechanism, closing the injection mould, and performing injection molding of the joint in the PE-RT pipeline joint area; ejection, namely opening the injection mould, driving the PE-RT pipeline to rotate to an ejection mechanism by virtue of the rotating mechanism, and ejecting the PE-RT pipeline by virtue of the ejection mechanism. According to the molding process of the PE-RT pipeline, the integration production of pipe molding and plastic connection molding is realized, the binding force of plastic pieces is increased, and the production efficiency is effectively improved.
