  • SYSTEM AND METHOD FOR FORMING 3D MODEL OF EJECTOR PIN OF MOLD
    Publication number: 20120173205
    Abstract: A system for forming a 3D model of ejector pins for a mold includes a 2D model drawing unit, an ejector pin parameter obtaining unit, and a 3D model drawing unit. The 2D model drawing unit opens a mold 2D model which includes a plurality of ejector pins. The ejector pin parameter obtaining unit obtains parameters of the plurality of ejector pins in the mold 2D model. The 3D model drawing unit automatically forms corresponding ejector pin 3D model according to the parameters obtained by the ejector pin parameter obtaining unit.
