Design of Injection Mould for Two-component Cover of MP4 Player
摘要
Abstract
According to the coated structure of a two-component cover of a MP4, two-component injection molding machine with rotary plane was adopted to molding it. The runner system was a combination of hot runner and cold runner. Latent gate and fan gate were adopted to molding the inner part and outer part respectively. Based on the flow analysis of Moldflow, the gate location was optimized firstly, and then the fill pattern, air trap distribution, injection pressure, clamp force and the time of ejection were predicted. These results were helpful for the design of the mould structure and the choice of the injection machine. Finally, the structure and working process of the two-component injection mould were introduced in detail.关键词
