Finite Element Flow Simulation and Mould Design for Injection Forming of New Mouse Base

The mouse is an important accessory in computer equipment and it is the goal of the designer The paper aims to design and create a new mouse which is easy to use and has complete function. A new mouse model This paper designs a new type of mouse with beautiful appearance and comfortable handle is designed, and the mouse model is was printed by 3D printing technology. Based on the design of gating system, the a finite element simulation on of the injection molding forming and flowing process of the new type of mouse base is was carried out. The Related parameters such as filling time, cooling and solidifying time, volume shrinkage rate, sink mark, the deformation of plastic pieces, orientation of surface and core, residual stress and weld lines during filling and forming process are were analyzed. Finally, design of the injection mold forming mould of the mouse base wasis designedcompleted. Developing new plastic products in Using the combination of 3D printing technology and finite element simulation to develop a new type of plastic products can saves the design time and ensures the quality of the design.
