A production process of high-strength injection-molded pipe fittings

Abstract

The invention discloses a production process of high-strength injection-molded pipe fittings, including batching, stirring, extrusion of blanks, vacuum setting and cut-to-length cutting; the invention can greatly increase the number of injection-molded pipe fittings by adding modified polyvinyl chloride resin in the production process of injection-molded pipe fittings. Excellent tensile strength and toughness, by adding fluoroelastomer processing aids, the surface finish of the prepared injection molding pipe fittings can be made higher, the combination of the two can effectively improve the quality of the production of injection molding pipe fittings, and use machinery instead of manpower for extrusion, It can make the components in the raw materials mix evenly and make the extrusion billet more uniform and finer, and the entire extrusion billet process is fully automated, which greatly improves production efficiency, effectively reduces labor intensity, and can promote better rotation performance of the extrusion screw, reducing The consumption of energy and the loss of the extruding screw facilitate the connection between the end of the discharge hopper and the storage cabinet, which is convenient for operation.

Description

technical field [0001] The invention belongs to the technical field of injection molding pipe fittings production, in particular to a production process of high-strength injection molding pipe fittings. Background technique [0002] The patent number is CN1186382C, which discloses a nano-polyvinyl chloride high-strength porous sleeve and pipe fittings and its production method. The main component is nano-scale CaCO 3 A special resin for in-situ polymerization with vinyl chloride monomer, a heat stabilizer, a lubricant, an impact modifier, a processing modifier, and a flame retardant; the method for producing the sleeve includes the following steps: batching, stirring, Extrusion, vacuum setting, cut-to-length, inspection, packaging, storage. With the development of the economy, the biggest hot spot of agricultural water transmission and distribution is the wide application of new pipes and pipe fittings. People's requirements for irrigation water utilization efficiency are ...

AI Technical Summary

Problems solved by technology

At present, there are mainly three kinds of pipe fittings commonly used in agricultural water transmission and distribution: injection molding pipe fittings, metal pipe fittings and composite pipe fittings. The surface smoothness is not enough and the surface is prone to spots, which seriously affects the production quality of injection molded pipe fittings. Due to long-term use, injection molded pipe fittings are prone to cracking, and the service life is short, which increases production costs;

[0003] The existing injection molding pipe fittings have certain deficiencies in the production process. The production efficiency is relatively low. The connection between the hopper and the storage cabinet brings inconvenience to the staff and increases labor intensity
