Abstract
The topic of this design is the injection mold design of the shell plastic parts. Through the computer software, the plastic parts of the shell plastic parts are modeled, and the original structure analysis of the plastic parts needs to be completed. Through the analysis and understanding, we can know that the internal structure and shape of the plastic parts are relatively simple, the overall shell shaped parts, and the average wall thickness distribution is relatively reasonable. After taking the first mock exam of the mold size and production efficiency into consideration, the design of this mold is to adopt a two cavity cavity with a mold and two plate die feeding method. It is necessary to analyze the material selection and molding process of plastic parts and determine the injection molding machine, so this mold design selects a more suitable injection molding machine, and checks and calculates several important parameters of the injection molding machine. The parting surface of the plastic part is selected and designed. After a variety of data comparison and analysis, so as to integrate various factors to choose the most reasonable scheme.
Key words: shell; injection molding; plastic parts process analysis; plastic mold.
