Based the CAE technology, the paper introduced the application of Moldflow Insight in injection mold design of mobile phone cover. First, we must preprocess the finite element model, including importing three-dimensional model, meshing, and process setting. And then, we can use preliminary simulation analysis to determine the number and location of the gate. Finally to filling, cooling, packing and warpage analysis for part which can help us to find the causes from warpage generated. By optimizing the molding process parameters, adjusting the dwell pressure and the dwell time we can get less warpage, which can meet the precision demand of parts, consequently, the result can provide gist for the mold designers to design and for the injection molding technologist to process parameter adjustment.

This article uses UG to establish the three-dimensional model for the automobile cover panel parts, and establish a parts technological addendum surface and binder surface. This model has been converted to DYNAFORM, in which the parts finite element model is established. It also uses DYNAFORM software to carry out simulation analysis and orthogonal analysis of the geometric parameters of rib, obtaining the influence rule of the drawbead geometric parameters to drawbead resistance. It has studied the influence of many factors on the parts forming such as blank size, blank holder force(BHF), the material parameter and so on. The result shows that during the process of stamping, the shape and size of blank has played an important role in the sheet flowing; BHF has a great influence upon the wrinkling and cracking of the parts; material parameter, the value of r, mainly affects the drawing deformation while the value of n produces a great impact on the plane strain, bulging deformation. Through optimizing the shape and size of the blank and BHF, it obtains the best material properties parameters to satisfy the parts smooth forming that is: 0.25, 2.15. After the scene stamping production, it confirms the practicality of the optimization solutions.

Abstract Injection molding is the most prevalent technology used for processing thermoplastic polymers. At the end of the injection molding cycle, the plastic molded part should be ejected when the injection mold opens. Complex moldings with bosses, ribs, or other features are generally ejected by ejector pins because they are economical and easy to be installed. However, the ejector pins can cause high local stresses and strains in the molding at the stage of ejection leading to the part deformation and damage. This paper proposes a method to determine the layout and size of the ejector pins required to eject thermoplastic moldings with minimizing the part deformation and damage. The proposed method calculates the distribution of the necessary ejecting forces to overcome the friction between the part and its mold. Then, it transforms the ejecting forces into a certain number of representative forces by the wavelet transform. Finally, we can get the location and size of the ejector pins corresponding to the discrete ejecting forces with the help of a rule-based system. The proposed method helps an injection mold designer to systematically obtain an optimum ejector design.
