Embodiment Construction

[0031] 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.

[0032] The injection molding process provided by the invention can be used for the injection molding of the washing machine cover, which is implemented based on a corresponding injection molding system and injection mold.

[0033] The injection molding system in the present invention uses a hot runner system for injection molding, and for the structural characteristics of the washing machine cover, the hot runners in the present invention are divided into 21 groups.

[0034] The injection mold is mainly composed of a moving mold and a fixed mold.

[0035] For the above situation, the specific implementation of its injection molding process is as follows (see figure 1 ):

[0036] (1) Raw material pretreatment

[0037] In this step, an oven is ...

Abstract

The invention discloses a cover plate injection molding technology of ABS (Acrylonitrile Butadiene Styrene) plastic washing machine, which comprises the following steps of: (1) preprocessing raw materials; (2) preprocessing an injection molding system and an injection molding mould; (3) plasticizing; (4) injecting; (5) maintaining pressure; (6) cooling and forming; and (7) demolding. The technology has simple implementation steps, effectively reduces forming cycle and production cost and effectively improves quality of finished product by corresponding technological 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 the aesthetic requirements of consumers for the appearance of washing machine covers, and to be more environmentally friendly, the use of spray-free high-gloss seamless injection molding technology to produce washing machine covers has...
