Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0027] The injection molding process provided by the present invention can be used for the injection molding of the air conditioner housing, which is implemented based on a corresponding injection molding system and injection mold.

[0028] The injection molding system in the present invention uses a hot runner system for injection molding, and for the structural characteristics of the air conditioner housing, the hot runners in the present invention are divided into 21 groups.

[0029] The injection mold is mainly composed of a moving mold and a fixed mold.

[0030] For the above situation, the specific implementation of its injection molding process is as follows (see figure 1 ):

[0031] (1) Raw material pretreatment

[0032] In this step,...

Abstract

The invention discloses an injection molding process for a polyphenylene oxide (PPO) plastic air conditioner shell. The process comprises the following steps of: (1) pretreating a raw material; (2) pretreating an injection molding system and an injection mold; (3) plasticizing; (4) injecting; (5) keeping pressure; (6) cooling for molding; and (7) demolding. The process is simple in implementation steps, the molding cycle is effectively shortened, and production cost is effectively reduced; meanwhile, the quality of a finished product prepared by the process is effectively improved through corresponding process conditions.

Description

technical field [0001] The invention relates to the field of injection molding, in particular to an injection molding process. 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] In order to meet consumers' aesthetic requirements for the appearance of air-conditioning shells and to be more environmentally friendly, the use of spray-free high-gloss seamless injection molding technology to produce air-conditioning shells has beco...
