Specifically, two fixed plates are clamped between the top and bottom of the corresponding end edges of the frames 2, and two fixed rods are arranged in the middle of the corresponding end edges of the frames 2. When installed, the frames 2 are arranged in parallel and clamp the fixed plates, so that the two end faces of the fixed plates abut against the opposite faces of the frames 2, preventing the distance between the frames 2 from decreasing, and the end portions of the fixed rods pass through the corresponding frames 2 and are buckled by the buckles 8 (as shown in Figure 4 The positioning rods 3 not only play a positioning role in the outer end of the first swing rod 4, ensuring that the mold plates 1 can be smoothly driven to translate, but also play a fixed positioning role in the frames 2, ensuring that the structural strength of the rack meets the use requirements and ensuring that the mold plates 1 can be closely fitted.
