The creation manner of ejection speed program pattern of the injection molding machine and it chooses the optional n place

摘要

The present invention is provided a method of making the injection speed program pattern of the injection molding machine by the accumulation of simple trial shots can continuously forming a good product without the need for most driving energy not require a high degree of skill judgment There, the branch portions and the flow path cross-sectional area of ​​the flow path of the molten resin in the mold cavity to select any n points over at least one position among the positions that vary stepwise, as a boundary the selected n points the inside of the mold cavity from the first filling section K1 until the n + 1 filling interval Kn to set interval, upper pressure limit P1 of the minimum injection pressure the molten resin that Mitsuru can be filled for each charging area K1 ..., P2 ... the is obtained, as a pressure upper limit value P1, P2 ... set to molding Z obtained for each charging area K1 ... the trial shot was carried out, a good article is obtained when injection speed measured value pattern speed priority control for the and characterized by an injection speed program pattern VPT.
