PROBLEM TO BE SOLVED: To provide a vertical injection molding machine with a turntable mechanism constituted so as to be capable of performing two-color molding and having the large degree of freedom in the selection of an injection pattern of two-color molding. SOLUTION: In the vertical injectiom molding machine equipped with an upper holding plate to which an upper mold is attached, a turntable to which a lower mold is attached, a mold on-off mechanism for relatively moving the upper holding plate and the turntable in an up and down direction and the injection unit arranged above the upper holding plate, two resin injection ports are provided to the upper mold to vertically arrange first and second injection units respectively corresponding to the resin injection ports and the turntable is rotationally driven in a mold opening state by a servo motor. The lower mold is made possible to locate at an arbitrary rotary position and the opposed state of the lower mold to the upper mold is made variable. COPYRIGHT: (C)2004,JPO&NCIPI
