by setting different injection time, or Mold flow software is used to analyze
data recorded by computer. Whether doing successive trials or being simulated
point by point, is very tedious. A new method is put forward-seeking the minimum
of curve being simulated by Lagrange interpolation. The minimum of the curve
is the best filling time. This method can improve the efficiency of the simulation
analysis. The software Mold flow provides the possibility to simulate the flow
processes of plastic air intake manifold with different gate location and number
of injection mold and to predict the position of air traps and weld lines. The
location and number of the gate in injection mold are determined by comparing
analysis results and avoid mold adjustment and mold repairing. Finished injection
mold of plastic air intake manifold on basis of simulation is perfect.]]>Zhang, H. and L. Quan,20124468475Liu, X., J. Pei, W. Fan and S. Yang,20124211219Yongmei, J.,20124101109Muller, K. and U.
