Injection mold design system and injection mold design method

An injection mold design system for correcting a profile of a product to be fabricated into a releasable profile from a mold so as to design an injection mold based on a corrected product shape, said system comprising:

• storing means for storing information of product shape or and mold profile;
• displaying means for displaying the product shape or the mold profile on a screen based on the information read from the storing means;
• inputting means for inputting designation information necessary for correction of the product shape or the mold profile;
• controlling means for unloading information of lines or planes being obstructive to correction of the product shape and the mold profile into the storing means in response to the designation information input by the inputting means, removing the lines or the planes from the screen, and replotting the line or the planes on the screen in terms of the information of lines or planes unloaded into the storing means after the correction operation of the product shape or the mold profile is completed;
• and
• means for forming an ejected profile having a range of manufacturing jigs of the mold parts as a sectional shape and transferring a profile of the mold parts to the ejected profile when an operator designates a range of the manufacturing to be used for manufacturing the mold parts against the displayed mold parts.
