The invention discloses a
wax mold injection process parameter determination method based on injection molding numerical
simulation. The
wax mold injection process parameter determination method comprises the following steps: determining actual
wax injection related conditions; establishing a finite
element model, and dividing the finite
element model by adopting a tetrahedral mesh; analyzing
sprue matching performance through numerical
simulation software Moldflow, and determining an optimal
sprue; according to actual conditions, selecting a plurality of wax injection process parameters as test factors, determining the parameter range of the test factors, and taking buckling deformation, a volume
shrinkage rate and sink marks as judgment results; According to the method, a Box-Behnken method is adopted in
Design Expert to carry out experimental scheme design, and numerical
simulation is carried out in Moldflow according to an experimental design scheme;
data analysis is conducted by utilizing
Design Expert to obtain an optimal wax injection process parameter; and a large amount of resources are saved, production efficiency is improved, and the phenomena of buckling deformation and volume shrinkage of the wax mold are effectively reduced, so the
production quality of the wax mold is improved.
