The area of the second arc-shaped surface 3021 is half of the area of the first arc-shaped surface 2021, so when the second pressure maintaining head 302 extends into the inner cavity of the workpiece P10 for pressure maintaining, the second arc-shaped surface 3021 can maintain the pressure of the bottom surface of the inner cavity of the workpiece P10, the side pressure surface 3022 is formed into a plane, so that the side pressure surface 3022 can maintain the pressure of the side surface of the inner cavity of the workpiece P10, and the second arc-shaped surface 3021 is also provided with the second contour groove 3023, so that the second contour groove 3023 can be matched with the reinforcing rib of the inner cavity of the workpiece P10, and further, the pressure maintaining is performed.

Referring to fig. 12 and 13, the bottom of the frame 10 is provided with a lead screw 601, the bottom of the slide plate 50 is provided with a lead screw motor 60 in transmission fit with the lead screw 601, and the lead screw motor 60 is used for driving the slide plate 50 to slide in the second direction, so that the first ram assembly 20 or the second ram assembly 30 is driven to a predetermined position.

Further, the sliding plate 50 has a sensing member 501 extending toward the frame 10, and the frame 10 is provided with a first triggering member 70 and a second triggering member 80 opposite to each other along the second direction; when the first ram assembly 20 moves to a predetermined position, the sensing member 501 corresponds to the first triggering member 70 to stop the movement of the sliding plate 50; when the second ram assembly 30 moves to a predetermined position, the sensing member 501 corresponds to the second triggering member 80 to stop the movement of the sliding plate 50.

In this embodiment, the second direction is a length direction of the screw rod 601, the screw rod motor 60 can move along the length direction of the screw rod 601, and further drive the sliding plate 50 to move along the second direction, thereby driving the first pressing head assembly 20 or the second pressing head assembly 30 to move to a predetermined position for pressure maintaining, and through the corresponding contact between the sensing element 501 and the first triggering element 70 or the second triggering element 80, the first triggering element 70 or the second triggering element 80 can send a triggering signal, and further control the screw rod motor 60 to stop rotating and stop the sliding plate 50; optionally, the frame 10 is provided with two dampers 90 along the second direction, the sliding plate 50 is correspondingly provided with a stop block 502, and when the sliding plate 50 moves to make the sensing member 501 correspond to the first trigger member 70 or the second trigger member 80, the stop block 502 can abut against one of the dampers 90, so as to perform buffering and deceleration, so that the stability is better in the pressure maintaining process.
