PROBLEM TO BE SOLVED: To provide an injection molding mold for a skin integration type interior finish material for a vehicle which effectively restrains the occurrence of a weld line and prevents the occurrence of wrinkles in a skin material, and to provide an injection molding method for the skin integration type interior finish material for the vehicle. SOLUTION: A molten resin is supplied into a cavity 7 between a cavity block 5 and a core block 6, in which gates 10 and 10 communicating with each other through a recessed channel 11 are installed through the gates 10 and 10, and the skin integration type interior finish material for the vehicle is molded in the cavity 7, so that the molten resin flows preferentially in the channel 11, the lowering of temperature is controlled, a flow front 13 is joined in the channel 11 separated from the skin material 3 to prevent the flow front 13 from pushing the skin material 3 forward, and the occurrence of the weld line are wrinkles is prevented.
