The utility model belongs to the technical field of double-color injection molding production, and provides a positioning mechanism for preventing injection molding parts from falling, which comprises a product, a fixed mold core, a movable mold core, a sliding block, a spring and a fixed mold core wedge-caulking piece, the product comprises a first injection molding part and a second injection molding part, and the fixed mold core wedge-caulking piece is positioned between the fixed mold core and the movable mold core and acts on the sliding block. The spring acts on the sliding block and enables the sliding block to have resilience force. The injection mold has the advantages that the sliding block can participate in glue sealing during first injection molding, a continuous pressing state is kept, a product is stably and effectively fixed, when the movable mold rotates, a clamping state can be kept continuously, a first injection molding part is prevented from loosening or being separated from a mold cavity
