Coupled Field Analysis for Optimum Design of an Injection Mold Cavity

摘要

Now-a-days in modern era molds are playing an important role in the manufacturing of plastic components. Generally in mold core is the male member, cavity is the female member. Generally the purpose of providing holes in a cavity is meant for solidification of casting. When hot metal comes in to contact with inner surface of cavity not only heat transfer will takes place but also there are some stresses due to clamping of mold assembly. For the purpose of increasing cooling rate, different numbers of holes are provided in the symmetric section of mold cavity. In this present work the mold cavity is considered as analysis member. The analysis is carried out in four cases at three, six, nine, twelve holes are provided in the section of mold cavity. Modeling and Analysis will be done by using Pro-E and ANSYS software which is based on FEA. The results obtained from four cases will be compared i.e., heat flow rate and von-mises stress and the best optimum case is suggested for improving productivity.
