Zusammenfassung:The invention relates to the technical field of injection molds, in particular to a forming mold based on automobile pedal production and capable of preventing advanced curing, and aims to solve the problem that in the injection molding process of an automobile pedal through an ABS material, due to the fact that the injection speed is too low, the disc pattern phenomenon is caused. A sprue bush is arranged on the upper die base and sequentially penetrates through the upper die base and the female die plate, a discharging port of the sprue bush is communicated with a pouring gate when the male die fixing plate and the female die plate are closed, a flow increasing channel is formed in the sprue bush, and a hydraulic control mechanism used for controlling the needle blocking station and the flow increasing channel to be connected and disconnected is further arranged in the sprue bush. The through-flow section of the injected raw materials is increased in the mode that the stop needle retreats from the pouring g
