In the production process of plastic boards, some non-standard-sized plastic boards are often required, while the sizes of the molds themselves are all standard sizes. Recasting non-standard-sized molds takes a long time and incurs additional costs. It is necessary to use an adjustable mold structure to produce some non-standard-sized plastic boards.

[0003] Chinese patent CN219466730U discloses an adjustable mold structure, including a mold groove, wherein mold plates are provided at the top and bottom of the mold groove, a circular hole is provided on the outer wall of one side of the mold groove, a feed pipe is fixedly connected to the circumferential inner wall of the circular hole, an adjustment plate is provided inside the mold groove, a card slot is provided at both ends of the adjustment plate, a sealing gasket is clamped inside the card slot, and the end of the sealing gasket away from the adjustment plate is in contact with the inner wall of one side of the mold groove.

[0004] In the above patent, after the rotating column bounces into the rotating groove, the adjusting plate can be pushed forward by rotating the fixed screw to reduce the internal area of ​​the mold. However, there is a lack of a fixed connection mechanism between the rotating column and the rotating groove, and rotating the fixed screw cannot drive the adjusting plate to move backward (when adjusting the size of the mold, the possibility of adjusting it in place at one time is low, and repeated adjustments are required), which makes it inconvenient to adjust the position of the adjusting plate and cannot drive the adjusting plate back to its original position. Therefore, a technical measure is proposed to solve the problem that there is a lack of a connection mechanism between the rotating column and the rotating groove, and rotating the fixed screw cannot drive the adjusting plate to move backward, which makes it inconvenient to adjust the position of the adjusting plate and cannot drive the adjusting plate back to its original position.
