Shell injection molding process for bluetooth sound equipment

Abstract

The invention relates to the technical field of bluetooth sound equipment, and particularly relates to a shell injection molding process for the bluetooth sound equipment. The shell injection moldingprocess comprises the following steps of designing a mold; granulating modified plastics, wherein 90-95 parts of synthetic resin, 3-5 parts of anti-aging agents, 2-3 parts of antioxidants, 4-7 parts of flame retardants, 3-5 parts of toughening agents and 1-2 parts of stabilizing agents are uniformly mixed by mass; drying plastic particles; carrying out injecton molding, conducting preheating on injection molding equipment and the mold, then setting parameters, and putting plastic master batches into the injection molding equipment for injection molding, wherein the injection molding step includes injection, pressure maintaining and cooling; demoulding and shaping; polishing and removing dust and static electricity; spraying an accelerant, conducting degreasing treatment on a semi-finishedshell through a degreasing agent, then spraying a nylon accelerant on the surface, and blow-drying the surface; and conducting product testing process flow. According to the shell injection molding process for the bluetooth sound equipment, the problem of insufficient existing spraying adhesive force in the shell surface of the bluetooth sound equipment can be solved, and anti-aging performance, anti-impact capacity and flame retardation performance of the shell are improved as well.

Description

technical field [0001] The invention relates to the technical field of bluetooth audio, in particular to an injection molding process for a bluetooth audio shell. Background technique [0002] With the development of science and technology, Bluetooth audio is more and more popular among consumers because of its portability and beautiful features. Through the built-in Bluetooth module of the Bluetooth audio, the Bluetooth connection replaces the audio equipment connected by the traditional wire, and achieves the purpose of convenience and speed through communication and connection with mobile terminals such as mobile phones, tablets, and notebooks. At present, the shells of Bluetooth speakers are all processed by injection molding. Injection molding materials generally use resin materials. The heat dissipation performance, aging resistance and impact resistance of the resin shell are often poor, and the flame retardancy is also insufficient. Moreover, in the existing techn...
