PROBLEM TO BE SOLVED: To provide a mold device for molding which can use a mold member fitted with a driving apparatus in common even when a gate position is changed. SOLUTION: A liner 31 and a gate 42 which makes the liner 31 communicate with a cavity 3 are installed in a fixed mold 1. A valve pin 57 which opens or closes the gate 42 and the valve pin 57, a hydraulic cylinder apparatus 63 are provided. A fitting hole 64 whose size in the direction crossing the axial direction of the valve pin 57 is larger than the cylinder apparatus 63 is formed in the fixed mold 1, and the cylinder apparatus 63 is installed in the hole 64 to be able to move in the crossing direction. By changing the position of the cylinder apparatus 63 in the hole 64 in accordance with the change of the position of the gate 42, it is possible to correspond to the change of the gate by using a common fixed side fitting plate 6.
