Processing and forming device for PE double-wall corrugated pipe

Abstract

A processing and forming device for a PE double-wall corrugated pipe includes an injection mold, an output end of the injection mold is provided with a molding device, the output end of the molding device is provided with a cutting device, and a cooling device and a drying device are disposed between the molding device and the cutting device; and a guide block is disposed on the output end of theinjection mold, and the guide block is horizontally arranged and sequentially passes through the molding device, the cooling device, the drying device, and the cutting device. Through adoption of thestructure, the production processing efficiency can be improved, the product quality can be ensured, and the performance of the double-wall corrugated pipe can be improved, so that a produced finishedproduct can meet various demands.

Description

technical field [0001] The invention relates to the field of PE pipe production equipment, in particular to a PE double-wall corrugated pipe processing and forming device. Background technique [0002] Double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. As a new energy-saving light-weight pipe, it has small specific gravity, low cost, external pressure resistance, high strength, and long service life. Convenience and other advantages. At present, plastic double-wall corrugated pipes are mainly used in underground drainage and sewage, rainwater collection, farmland drainage and irrigation, industrial wastewater discharge and other fields in municipal construction. [0003] At present, most of the cooling of the mold of the double-wall corrugated pipe forming machine adopts the air-cooling method. Generally, fans are installed at the upper and lower ends of the mold, and the fan is used to cool the mold by blowing air. Thi...

AI Technical Summary

Problems solved by technology

This cooling method is inefficient, the cooling effect is not good, and it does not help much to increase the molding speed;

[0004] In addition, due to the simple structure of the conventional double-wall bellows, which are both inner and outer double-layer structures, its performance improvement prospects are small, and a series of performance improvements such as the wear resistance of the pipe wall can only be improved by improving raw materials.
