PROBLEM TO BE SOLVED: To provide a resin molding mold which can prevent a coating from leaking out to a surface other than the product surface of a molding and improve the design of the product surface of the molding. SOLUTION: A space 110 which communicates with the vertical wall end part of a cavity C is formed in a movable mold 102. A cavity insert 120 moving slidably along the inner surface of the space is set in the space 110. A spring 140 as a pressing means which presses the cavity insert 120 toward a resin 11 supplied to the cavity C is installed between the lower surface of the cavity insert 120 and the bottom surface of the space 110. The cavity insert 120, as shown in Fig.2(C), follows the contraction of the resin by upward pressing by a spring 140 and moves in the upper direction (resin side) of the figure. By appropriately setting pressure by the spring 140, the cavity insert 120, as shown by Fig.2(D), moves in accordance with the pressure applied by the injection of the coating 13.
