Apparatus for injection molding front load washing machine cover assembly

Abstract

The invention provides a device for injection molding of a cover assembly of a roller washing machine. A feeding cylinder of the device can also achieve a raw material preheating function, and great optimization is made on the aspects of heat energy waste and electric energy consumption, so that the production cost during injection molding is effectively reduced. The device comprises a cylinder body provided with an upper part and a lower part. The upper part is a heating cylinder, the lower part is a heat-preservation cylinder, and the bottom of the heating cylinder and the bottom of the heat-preservation cylinder are each in a funnel shape. A conveying pipe used for conveying materials into an injection molding machine is connected to the lower portion of the heat-preservation cylinder. An electromagnetic valve is arranged at the bottom of the heating cylinder. The outer surface of the funnel-shaped portion of the bottom of the heating cylinder is spirally provided with heat-conducting pipes and covered with a heat-insulation plate. Heat-transfer media circulate in the heat-conducting pipes and are heated through a solar heat collector. A circulating pump is arranged on the portion, at the input end of the solar heat collector, of a pipeline. A stirrer is further arranged in the heating cylinder.

Description

technical field [0001] The invention relates to the technical field of washing machine cover production equipment, in particular to a device for injection molding a drum washing machine cover assembly. Background technique [0002] The cover components of the drum washing machine are plastic products. During production, most of the components are injection molded by injection molding machines. After the components are formed, the complete cover components are obtained by manual or machine assembly. Therefore, the injection molding machine is One of the important production equipment of the washing machine cover assembly, and the device used for injection molding is not only the injection molding machine, that is to say, in the injection molding process, there are generally multiple devices that cooperate to complete. The need for improvement, it is possible to improve one device to have a positive effect on the entire injection molding process, or to improve several devices ...

AI Technical Summary

Problems solved by technology

[0005] However, this kind of feeding cylinder uses the hot air passing through the heating air pipe as the heat source, and the hot air in the heating cylinder is finally discharged to the natural environment through the ventilation pipe, which causes a large amount of waste of heat energy in the hot air. In the process, the hot air pipe needs to continuously feed hot air into the heating cylinder to ensure the normal progress of preheating. At present, most of the hot air is generated by hot air blowers and other equipment, which relatively causes a huge power consumption and improves the Production cost of injection molding
