AI Technical Summary

Problems solved by technology

The current extrusion molding process produces high production costs for inner rib reinforced spiral corrugated pipes. At the same time, because the joints are welded by plates, the welding equipment is heavy and the construction is inconvenient. Therefore, we propose a production process for injection molding joints

Embodiment

[0020] A production process of an injection molded joint, comprising the steps of:

[0021] S1. Select raw materials: select PE materials, remove impurities in PE materials, and then mix and stir the selected raw materials;

[0022] S2. Extrusion molding: heating the extruder before extrusion molding, then feeding the mixed and stirred raw materials into the extruder, and extruding them into the mold through the extruder to form a preform;

[0023] S3. Cooling and demoulding: take the mold of the preform out of the extruder, and then cool it through the cooling group to ensure that it can be more complete during demoulding;

[0024] S4. Pre-embedded copper wire and apron: pre-embed the copper wire into one end of the injection joint after demoulding, and fix the apron inside one end of the injection joint, and then do the final cooling;

[0025] In order to ensure the realization of the electrofusion double sealing ring connection process, we require the minimum length of the...

Abstract

The invention discloses a production process of an injection molding joint. The production process comprises the following steps: S1, selecting raw materials: selecting PE materials, removing impurities in the PE materials, and then mixing and stirring the selected raw materials; S2, carrying out extrusion molding: heating an extruder before extrusion molding, then feeding the mixed and stirred raw materials into the extruder, and extruding the mixed and stirred raw materials into a mold through the extruder to form a preform; S3, carrying out cooling and demolding: taking the mold of the preform away from the extruder, and then carrying out cooling by a cooling group to ensure more integrity during demolding; and S4, pre-embedding a copper wire and a rubber ring: pre-embedding the copperwire into one end of the demolded injection molding joint, and fixedly connecting the rubber ring inside one end of the injection molding joint. Compared with other production technologies, the production process has the advantages of low price, mature process, stress resistance, excellent water-tight performance, firm connection, convenient mounting, no need of a special construction site, flexible joint, and strong capability of resisting uneven settlement, and greatly improving the use quality of the injection molding joint.

Description

technical field [0001] The invention relates to the technical field of pipes and their processing, and more specifically, relates to a production process of injection molded joints. Background technique [0002] The polyethylene structural wall winding pipe has the advantages of corrosion resistance, low frictional resistance, wear resistance, etc., has high ring stiffness, deep buried, and good overall molding process, high seam tensile strength and corrosion resistance, and longer life; With a variety of reliable and convenient connection. This kind of pipe has become a hot spot for investment in plastic drainage and sewage pipes. At present, there are A-type pipes, B-type pipes, and inner rib-reinforced spiral corrugated pipes for polyethylene structural wall winding pipes. In the connection of this type of composite pipe, the joint pipe fitting and its connection structure with the pipe are very important. The current manufacturing method of the inner rib reinforced s...
