[0023] The mold cavity 2 is formed on the lower mold base 3 , and the mold core 10 has the same specifications and corresponding positions as the mold cavity 2 . The paper plate is formed under the action of the mold cavity 2 and the mold core 10 .

[0024] The receiving cavity 12 is formed on the upper die base 6 , and the fixing cavity 13 is circumferentially divided in the receiving cavity 12 . The receiving cavity 12 can receive the pre-fixed ring 7 , thereby ensuring that the upper die base 6 and the lower die base 3 are in close contact during the mold closing process.

[0025] The fixed part of the telescopic rod 9 is fixedly connected to the storage cavity 12, and the spring 8 is welded to the outer wall of the telescopic rod 9. The combination of the telescopic rod 9 and the spring 8 can ensure that the upper mold base 6 continues to move down for mold closing after the pre-fixing ring 7 presses and fixes the paper plate.

[0026] The pre-fixing ring 7 is fixed to the movable end of the telescopic rod 9 by screws. The specifications of the pre-fixing ring 7 are consistent with the specifications of the storage cavity 12.
