Abstract:
An injection mold design method for designing the core and the cavity by correcting the profile of the product to be fabricated into a releasable profile from the mold, then arranging the corrected product shape in the mold block being displayed on the screen to provide a cavity corresponding to the product shape in the mold block, and then splitting the mold block, said method comprising:detecting a bottom of the cavity in the core side;extending a peripheral portion of the bottom along a mold opening direction so as to select candidates of the split line for splitting the core of the mold block into a nest structure;displaying a result of resin superplasticized analysis of the mold superposedly on a perspective view of the mold viewed from the mold opening direction;arranging a gas vent for exhausting gas in a location where a resin reaches finally based on the result of the resin superplasticized analysis;patternizing gate structures of the mold into plural groups in advance;registering the plural groups of patternized gate structures in a storing device; andselecting one of the stored patternized gate structures by an operator in compliance with procedures displayed on a screen.
