Gas assisting injection molding process of external opening handle

Abstract

The invention discloses a gas assisting injection molding process of an external opening handle. The gas assisting injection molding process of the external opening handle includes raw material adopting, raw material receiving, burdening, injection molding, grinding, final inspection and warehousing. Commonly used raw materials for production raw materials of traditional handles comprise polycarbonate, acrylonitrile-butadiene-styrene plastics, polyethylene terephthalate and the like, the quality problems that the product strength is low and floating fibers happen to the appearance easily happen, and the rejection rate is high; and by replacing the raw materials with nylon, fibers and injecting molding materials meeting requirements, produced handles are excellent in performance, and soft and smooth in appearance, the quality problem of floating fibers of the surfaces of products in production is solved, and the rejection rate of the products is decreased by 30%. The gas assisting injection molding process can be applied to any thermoplastic plastics except especially soft plastics and part of thermosetting plastics, and thus, besides production of an external opening handle body, the gas assisting injection molding process is especially suitable for various large-wall-thickness workpieces similar with the type of handles.

Description

technical field

[0001] The invention relates to the field of injection molding of outwardly opening handles, in particular to a gas-assisted injection molding process of outwardly opening handles. Background technique

[0002] The injection molding process is a very important technology type in the processing of plastic products. The processing of plastic parts in most industries requires the injection molding process to complete. It involves a wide range of industries and fields, such as food, electronic appliances, instruments, automobiles and motorcycles, daily use, chemical industry, agriculture, transportation and other industries can use plastic components manufactured by injection molding technology. The new technology of gas-assisted injection molding in this project, that is, gas-assisted injection molding technology, is one of the most important developments in injection molding technology since the advent of the reciprocating screw injection machine. It uses high...
