Problems solved by technology

Most of the existing FRP elbows are hand-made elbows with seams. There are many seams, and steel pipes need to be used first, and then cut and polished. Steel is easy to rust, and it is difficult to repair, and the production efficiency is relatively low. Quality is also difficult to guarantee

Abstract

The invention relates to a glass reinforced plastic elbow die and a manufacturing method thereof. The die comprises an end cover, a connection section die, an elbow die body, an intermediate plate and a pull rod. The elbow die body consists of an elbow inner template and an elbow outer template which are made of glass reinforced plastic material. The lengths of arc seams at both sides, which are butted in a matching mode, are at least 10mm. The connection section die is one of a straight tube connection section die, a butting connection section die, a socket connection section die and a lap joint flange connection section die. The manufacturing method of the elbow die body comprises the following steps of: 1, making a scraper; 2, making a cement die; 3, duplicating a glass reinforced plastic die; 4, carrying out machining; and 5, carrying out surface polishing treatment. The glass reinforced plastic elbow die and the manufacturing method solve the problem that the steel is easy to rust, are easy to repair, have the advantages of simple structure, high precision, high quality, high productivity and low manufacturing cost and are easy to demould. A product produced by the elbow die has a smooth inner wall, good seepage prevention performance and attractive appearance. The materials are saved. Due to the adoption of the elbow die, not only can the requirement of a hand lay-up process be met, but also the requirements of a mechanical winding process can be met.

Description

technical field [0001] The invention relates to a mold, in particular to a glass fiber reinforced plastic elbow mold and a manufacturing method thereof. Background technique [0002] FRP elbow is an important accessory for the installation of FRP pipes, and its quality directly affects the installation quality of the entire pipeline. Most of the existing FRP elbows are hand-made elbows with seams. There are many seams, and steel pipes need to be used first, and then cut and polished. Steel is easy to rust, and it is difficult to repair, and the production efficiency is relatively low. Quality is also difficult to guarantee. Contents of the invention [0003] A technical problem to be solved by the present invention is to remedy the defects of the above-mentioned prior art and provide a glass fiber reinforced plastic elbow mold. [0004] Another technical problem to be solved by the present invention is to remedy the defects of the above-mentioned prior art, and provide a...
