The forming process analysis and mould design for the remote control of the vertical air conditioner

Abstract: The design of the injection mould for the upper cover of the vertical air conditioner is introduced in detail in this paper. Through the three-dimensional modeling function of UG software, the parts are modeled, the process of the parts is analyzed, the plan is made, and the optimal design scheme is determined. Through the analysis of the plastic part and the selected material, determine the parting surface, select the injection machine, and design the pouring system and calculate the size of the molding parts. Because the plastic part has a groove, the side core pulling mechanism of the inclined sliding block is adopted, and the design and calculation of the ejection, cooling system and the exhaust system of the push rod mechanism are determined according to the calculation of the ejection force. The structure of the mold and injection molding machine matching check to ensure that the design of a variety of structures to make the work of the mold safe and reliable. Three dimensional modeling of each mechanism is carried out by using the 3D modeling function of UG, and drawing die assembly drawing.

Key words: Injection mould; remote control upper cover; inclined slide block
