Description

Technical Field

[0001] The present invention relates to the technical field of processing molds, and more specifically, to an integrated winding elbow assembly mold. Background Art

[0002] In the piping system, elbows are fittings that change the direction of the pipeline. According to the angle, there are three most commonly used elbows: 45°, 90° and 180°. In addition, according to the needs of the project, there are also other abnormal angle elbows such as 60°. The materials of elbows are cast iron, stainless steel, alloy steel, forgeable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect with the pipes include: direct welding (the most commonly used method), flange connection, hot melt connection, electric fusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welded elbow, stamped elbow, push elbow, cast elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle elbow, love elbow, etc.

[0003] The prior art has the following deficiencies: the original FRP elbow processing mold is designed as a metal structure, and is a longitudinally split structure, which is heavy and requires manual material bonding and pasting. After processing, the upper mold and the lower mold need to be pulled apart in reverse to complete demoulding; the FRP elbow after manual processing and demoulding is extremely rough and requires strength grinding to meet the requirements of the finished product. The processing cost is high, time-consuming and labor-intensive, and the wall thickness of the finished product is irregular and non-standard, and cannot be used in any venue; the original mold processing model is single and cannot be applied to the market for processing elbows of other angles; the finished product of the elbow and the socket cannot be completed in one piece, and the two parts need to be processed separately and then bonded. The life of the finished product after bonding is short, and the production cost is high and the standardization level is low. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an one-piece winding elbow assembly mold. The present invention realizes demoulding by first unscrewing the nuts at both ends of the wire rope, removing the sealing plate and the socket sleeve, and then removing the assembling blocks on the inner sides of both ends of the mold, and finally pulling the finished product of the winding molding to one end; the assembling blocks are added to facilitate the demoulding of the finished product. Because the socket is slightly wider than the elbow, the operating space is increased by removing the assembling blocks and then pulling outward, which is more convenient for disassembly; the FRP assembly mold is light in weight and can realize the production and processing of FRP elbows of different angles and types through assembly; by connecting a motor to rotate and wind at a uniform speed, the produced products are more standardized, the production efficiency is high, and the production cost is reduced, so as to solve the problems raised by the above-mentioned background technology.

The finished product has a short life after bonding, and the production cost is high and the standardization level is low.
