Structural Design and Numerical Simulation of Injection Mold for Unequal Thickness Multi-Rib Vertical Column Panel
This paper uses the plastic components of an automobile column panel as an illustrative example,characterized by intricate details and varying wall thicknesses.With the help of the heat transfer model of mold cavi-ty,design parameters of cooling system were calculated,analyzed and obtained.By integrating mold flow analysis to validate the equilibrium of mold temperature distribution,it was determined that the temperature difference between the inner and outer surfaces of the cavity was less than 15 ℃.The time for the mold to reach temperature stability was about 450 s.Finally,according to the results of mold flow analysis and the characteristics of plastic parts process structure,the structure design of injection mold for vertical column panel was carried out.Inside feed of curved sur-face parting latent injection gate was adopted,and the two-plate structure of inner and outer core-pulling is com-pleted by side slide block and inclined top.Empirical evidence demonstrates that the mold satisfies the production requirements for the products.
