2.The experimental results point that the actual head on ingate and the velocity of ingate are determined by both the total static head and the cros-sectional area ratio of sprue to ingatc.
3.In this paper, effects of gating system structure, including the metal static head, the ingate area, gating system radio and the ingate locations, on the fluidity of AZ91 magnesium alloy in the expendable pattern casting (EPC) process have been investigated.
4.Is used in thin Gao Xing Qiang and sprinkle the occasion of narrow around space.
5.According to the large orifice discharge theory, we adopt the distributive sprue system, and put the chocked section in the entrance of pouring cup. Thus the size of distributive sprue system is large than that of the main one, the inner sprue size of every layer is equal to the sprue section size. During the filling process, by controlling the sprue’s sufficient degree, shape and structure, and changing the direction of metal liquid and resistance, the ordinal afflux of step type gating system are realized.
6.In inject makings because of no longer the runner material that mix into processes repeatedly into the course, reason product quality can get rising significantly, because gating system is plastic,maintain melt at the same time, loss of the pressure when flow is small, easy implementation is many runner, consequently much model the low pressure of antrum mould and large goods injects.
7.To runner cup temperature high molten iron have, fluctuate the liquid, the liquid post interferes etc. influencing the factor measured when pouring in real time this text, have taken the detection method based on treatment technology of the picture 。
8.The relation between the depth of gate and the Archimedes flow length is nonlinear, and the H-L curve is of obvious wave.
9.This article first introduces the function and the application of MoldFlow and Pro/Plastic Advisor, then introduces the process of using Plastic Advisor to optimize the design of injection mold gates.
10.Finally, the INLET4 was recommended as the optimal injection position. Good products that have passed through the acceptance check of relative department are made according to the simulation results.
