Using Injection Molding Process for Manufacturing a HDPE Mini Wheel
並列摘要
Polymer industry is more and more important with many practical applications, especially plastic mini wheels. With many various shapes and sizes of mini wheels used widely in the families and companies. Moreover, injection molding is the most effectively used process to manufacturing plastic products. In this paper, a combining design and three kinds of software were used to fabricate a prototype of mini wheel. First of all, a model of mini wheel was created by using Pro-E software and then Ansys software used to check sustainable loading capacity of mini wheel. Next, a cooling system was built through using Creo Prametric 1.0 software. The final, Moldflow-CAE software used to analyze the fill time of runner system, the temperature, the pressure, and defects in designing of mini wheel mold. The results showed that the injection plastic flow of the runner with two gates on one product will be better than that of one gate or three gates because it will be easy to move plastic to cavity of product. Besides, Moldflow software can identify some parameters such as the fill time, the pressure and the others that effect on injection molding process. Kinematic and static equations were formulated. The FEA results are a good agreement with the PRBM. The optimal results indicated that the input horizontal force of 0.8896 N and rotary angular of 0.4363 radian. An input rotational angle is the most significant parameter with contribution of 44.2544 %. The fatigue analysis determined that the mechanism could reach approximately one million life cycles before failure.
