When the ultrahigh pressure sensor detects that the pressure of the flexible forming medium in the mold is lower than a set value, the ultrahigh pressure source injects the ultrahigh pressure flexible forming medium into the mold through one ultrahigh pressure one-way valve, so that the pressure of the flexible forming medium in the mold reaches the set value, and the ultrahigh pressure safety valve ensures that the system pressure does not exceed the safety pressure; when the ultrahigh pressure sensor detects that the pressure of the flexible forming medium in the mold is higher than a set value, the ultrahigh pressure flexible forming medium in the mold flows back to the ultrahigh pressure source through the ultrahigh pressure check valve, the ultrahigh pressure filter and the ultrahigh pressure sensor, so that the pressure of the flexible forming medium in the mold reaches the set value. The ultrahigh pressure source is controlled by a high-frequency response servo valve, and can be quickly adjusted according to a pressure signal in the die, so that the pressure of a flexible forming medium in the die meets the forming requirement of a workpiece. The ultrahigh pressure filter is arranged on a loop of the ultrahigh pressure flexible forming medium flowing back to the ultrahigh pressure source, so that the condition that pollutants in the liquid filling forming die enter the ultrahigh pressure source to cause faults is avoided, and meanwhile, the two ultrahigh pressure sensors are arranged on the two sides of the ultrahigh pressure filter, so that whether the filter element of the ultrahigh pressure filter needs to be replaced or not can be judged by detecting the pressure difference on the two sides of the ultrahigh pressure filter. By the design, on the premise of meeting the requirement of a process pressure curve, the long-term stable operation of the liquid-filling forming equipment can be ensured, the production efficiency of the equipment is improved, the production cost is saved, and meanwhile, the production safety is also ensured.
