摘要：
A pressure-controlling device is used in an injection mold that includes a movable component, a stationary component, and a cavity defined by the movable and stationary components. The pressure-controlling device includes a piezoelectric actuator, a pressure sensor, and a control unit. The piezoelectric actuator is connected to the movable component for actuating the movable component. The pressure sensor is connected to the stationary component, and outputs a signal in response to pressure in the cavity. The control unit is connected electrically to the piezoelectric actuator and the pressure sensor, processes the signal from the pressure sensor, and controls the piezoelectric actuator to move the movable component and to adjust the pressure in the cavity.
