An injection molding machine that distinctively displays operation parameters attributed to molds, which are set by designating a mold to be used, and the other operation parameters, to thereby prevent setting errors. The machine has storage means for storing and saving the operation parameters attributed to molds, which are determined by molds, with respect to each mold, and storage means for operation parameters to be applied for operating the injection molding machine. In the storage means for operation parameters to be applied, the stored operation parameters attributed to molds are read out to be set, and the other operation parameters are each stored. When the operation parameters stored in the storage means for operation parameters to be applied are set and displayed, the display appearances of the operation parameters attributed to molds and that of the other operation parameters are differentiated from each other. In the drawings, parameters provided with .star-solid. are operation parameters attributed to molds, and those not provided with .star-solid. are the other parameters. The other operation parameters that need to be set and the operation parameters attributed to molds, which hardly need to be altered, are displayed distinctively, resulting in a reduction in setting errors.
