Problems solved by technology
[0005] However, the existing technology for injection molding air-conditioning shells still has certain defects in the implementation process, such as long cooling time, which needs to account for 70-80% of the entire molding cycle, and uneven cooling, which is very easy to make the injection molding The product is warped and deformed, the process steps are complicated, the molding cycle is long, and the cost is high. At the same time, the quality of the finished product of the existing process is not high, and it is difficult to meet people's production requirements.

Embodiment Construction
[0033] 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.
[0034] refer to figure 1 As shown in the figure, an improved air-conditioning housing injection molding process is shown in the figure, including the implementation of the process using a corresponding injection molding system and injection mold. The injection mold is mainly composed of a movable mold and a fixed mold.
[0035] Its process concrete steps are as follows:
[0036] (1) raw material mixing 100
[0037] The crushed raw material is mixed with the raw material for injection molding air conditioner housing.
[0038] (2) Stir 200
[0039] The mixed raw materials are stirred by the stirring device, and the raw materials can be mixed more uniformly after being stirred by the stirring device.
[0040] (3) Raw material pretreatment 300 ...

Abstract
An improved injection molding process for an air conditioner shell is disclosed. The process is implemented by adopting a corresponding injection molding system and an injection molding mold. The process includes (1) raw material mixing, (2) stirring, (3) raw material pretreatment, (4) device pretreatment, (5) raw material plastification, (6) mold assembling, (7) raw material injection, (8) pressure maintaining, (9) cooling and molding, (10) mold disassembling, (11) molded shell withdrawing, (12) mold cleaning, (13) examination, (14) finished product warehousing, (15) crushing and (16) sieving. The process has characteristics of short cooling time, uniform cooling, and simple implementation steps. The period and production cost of product injection molding are effectively reduced, and through corresponding process conditions, product quality is effectively improved, facilitating environment protection.
Description
technical field [0001] The invention relates to the technical field of injection molding, in particular to an improved injection molding process for an air conditioner casing. 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 techn...
