Plastic mold capable of realizing high-frequency large-amplitude vibration of cavity

The invention relates to a plastic mold for achieving high-frequency large-amplitude vibration of a cavity, and relates to the technical field of forming equipment, the plastic mold comprises a mold box, a driving motor, a cam, the cavity and a reset spring, the driving motor is fixedly connected to the mold box, the cam is rotatably connected to the output end of the driving motor, the cavity is internally provided with a cavity for injection molding, and the cavity is slidably connected to the interior of the mold box; the cam abuts against the top of the cavity. The reset spring is fixedly connected to the mold box, and one end of the reset spring abuts against the bottom of the cavity so that the top of the cavity can abut against the cam all the time. Wherein the cam is a petal-shaped multi-head cam, and the design size of the cam meets the requirement that the mechanical property and the appearance quality of a polymer are improved. 本发明涉及一种实现型腔高频大振幅振动的塑料模具，涉及成型设备技术领域，包括模箱、驱动电机、凸轮、型腔和复位弹簧，驱动电机固连在模箱上，凸轮转动
