In the process of the downward movement of the downward circular plate 16, the angle and position of the support rod 19 are adjusted. The position is adjusted so that the arc-shaped clamping plate 14 can be opened to contact the inner wall of the formed plastic water cup and squeeze the plastic water cup to limit the position. Then the staff restarts the No. 2 electric push rod 11 to drive the circular fixing frame 12 to move up, so that the plastic water cup can be separated from the forming groove without damage. After the plastic water cup is separated from the forming groove, the staff restarts the No. 3 electric push rod 15 to return the arc-shaped clamping plate 14 to the initial position. Then the staff restarts the transmission motor 6 to move the No. 1 slider 7 back to the top of the forming groove, so that the mold can continue to be used normally. The above control method can be performed manually or automatically by programming on the control panel.
