    摘要： An object of the present invention is to provide a method for designing a mold and a method for producing an injection molding in which a mold clamping force or weld line occurrence can be more accurately controlled in the case of injection molding of a resin product. In the case where an injection molding is carried out using a mold having a plurality of resin inflow conduits G1, G2, G3 to a cavity CV, a mold design parameter in relation to at least one of the arrangement, the shapes and the sizes of the resin inflow conduits is determined by the combination of a numerical analysis method for calculating an injection molding process and a computer-aided optimization method, for the purpose of obtaining a preferable injection molding condition. Thereby the mold design parameter can be promptly and accurately calculated without repetition of trial and error manually.

    摘要： A bumper reinforcing member formed of a resinous material is provided between a bumper fascia and a vehicle body. The reinforcing member includes a plurality of horizontal plates disposed approximately along a horizontal plane and a plurality of vertical plates integrally connected to the horizontal plates and disposed approximately along a vertical plane. A line connecting the position at which an impact is received at the front end of the horizontal plate on the bumper fascia side and a mounting position on the rear of the reinforcing member on the vehicle body side forms an angle with the horizontal plane.
