Abstract

The invention relates to injection moulding technology for a remote controller housing. The technology comprises: S1, pretreatment of raw materials; S2, pre-heating of an injection moulding cylinder;S3, preheating of a die; S4, a hot melting stage; S5, an injection moulding stage; and S6, cooling moulding. The pretreated material obtained in the step S1 is added to a first section of the preheated injection moulding cylinder in the step S2; after 150-180 s, the melt plastic is pushed to a second section of the preheated injection moulding cylinder in the step S2; after 240-280 s, the melt plastic is pushed to a third section of the preheated injection moulding cylinder in the step S2; and after 120-150 s, the melt plastic is pushed to a preheated injection moulding nozzle in the step S2.In the technology, the raw materials are not prone to be oxidized and are good in processing performance, and the remote controller housing is high in mechanical strength.

Description

technical field [0001] The invention relates to the technical field of plastic product manufacturing technology, in particular to an injection molding process for a remote controller shell. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. [0003] An injection molding machine (injection molding machine) has two basic components: the injection unit and the clamping unit for melting and feeding the plastic into the mold. The function ...
