[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides as Figures 1 - 3The forming die for processing paper trays shown in the figure includes an upper die 1 and a lower die 2. The upper die 1 and the lower die 2 are distributed vertically. A plurality of positioning rods 3 are arranged between the upper die 1 and the lower die 2. The bottom end of the positioning rod 3 is fixedly arranged with the top end of the lower die 2. The top end of the positioning rod 3 penetrates through the top end of the upper die 1 and extends above the upper die 1.

[0022] As Figure 1 and Figure 2 As shown in the figure, after the upper die 1 and the lower die 2 are aligned, a die for forming a paper tray is formed. Through the arrangement of the positioning rods 3 between the upper die 1 and the lower die 2, when the upper die 1 and the lower die 2 are aligned, the insertion of the positioning rods 3 into the upper die 1 can be utilized, thereby improving the alignment efficiency and accuracy of the upper die 1 and the lower die 2, and effectively improving the use efficiency of the paper tray forming die.

[0023] A pressing structure 4 is arranged between the upper die 1 and the positioning rod 3. The pressing structure 4 includes an installation cylinder 401, a pressing rod 402 and a limiting component. The installation cylinder 401 is fixedly arranged at the top end of the upper die 1. The pressing rod 402 is movably arranged in the inner cavity of the installation cylinder 401. The pressing rod 402 is used to move the positioning rod 3 downward. The top end of the pressing rod 402 penetrates through the top end of the installation cylinder 401 and extends upward. The cross-section of the pressing rod 402 is convex. The convex shape setting makes it difficult for the pressing rod 402 to fall off from the installation cylinder 401, improving the installation stability and use effectiveness of the pressing rod 402. A spring 403 is fixedly arranged between the pressing rod 402 and the installation cylinder 401. The limiting component is arranged between the pressing rod 402 and the positioning rod 3. The limiting component is used to limit the position of the positioning rod 3 in the inner cavity of the installation cylinder 401.

[0024] As Figure 2As shown in the figure, the inner cavity of the installation cylinder 401 has a hollow structure, and the top end of the installation cylinder 401 is in a communicating state with the inner cavity of the installation cylinder 401. The bottom end of the installation cylinder 401 is connected to the space through which the positioning rod 3 penetrates at the top end of the upper mold 1, providing an effective space for the insertion and installation of the pressure rod 402. A spring 403 is sleeved on the outer wall of the pressure rod 402. One end of the spring 403 is fixedly arranged on the outer wall of the pressure rod 402, and the other end of the spring 403 is fixedly arranged on the inner wall of the installation cylinder 401. The pressure rod 402 can be movably installed in the inner cavity of the installation cylinder 401 by means of the spring 403, and the top end of the pressure rod 402 extends out of the top end of the installation cylinder 401. After the positioning rod 3 penetrates the top end of the upper mold 1, it will enter the inner cavity of the installation cylinder 401. When it is necessary to separate the upper mold 1 and the lower mold 2, the pressure rod 402 can be pressed, causing the pressure rod 402 to move downward. During the downward movement, a downward pressure will be generated on the positioning rod 3, enabling the positioning rod 3 to be quickly separated from the upper mold 1, and then the lower mold 2 can also be separated from the upper mold 1, avoiding the phenomenon that the upper mold 1 and the lower mold 2 are not easily disassembled after use, improving the convenience and efficiency of the disassembly and assembly of the upper mold 1 and the lower mold 2, and further enhancing the efficiency of the paper tray demoulding.

[0025] The limiting component includes a limiting rod 404 and a limiting groove 405. The limiting rod 404 is fixedly arranged at the bottom end of the pressure rod 402, the limiting groove 405 is opened on the outer wall of the positioning rod 3, and the limiting rod 404 is movably inserted into the inner cavity of the limiting groove 405. The cross-sections of both the limiting rod 404 and the limiting groove 405 are L-shaped. The top end of the inner cavity of the limiting groove 405 is connected to the top end of the positioning rod 3, and the limiting rod 404 is made of elastic plastic.

[0026] As Figure 2 and Figure 3 As shown in the figure, the limiting rod 404 is made of elastic plastic, so that the limiting rod 404 can generate elastic deformation under extrusion. For example, when the top end of the positioning rod 3 passes through the top end of the upper mold 1 and extends into the inner cavity of the installation cylinder 401, as the positioning rod 3 continues to rise, the top end of the positioning rod 3 will exert extrusion on the limiting rod 404. Since the end of the limiting rod 404 facing the positioning rod 3 is arc-shaped, the squeezed limiting rod 404 will move towards the inner wall of the installation cylinder 401, enabling the positioning rod 3 to continue to move upward until the limiting rod 404 moves to the position of the limiting groove 405 and will pop out by its own elastic recovery performance and be inserted into the inner cavity of the limiting groove 405. Then, the positioning rod 3 can maintain the stability of its own position by the insertion connection of the limiting rod 404 and the limiting groove 405, ensuring the stable insertion connection between the positioning rod 3 and the upper mold 1 without a reverse downward pressure, and enhancing the fastening of the combination of the upper mold 1 and the lower mold 2 during use.

[0027] As Figure 3As shown, the cross-sections of the limiting rod 404 and the limiting groove 405 are both L-shaped. On the one hand, the elastic structure of the limiting rod 404 can be inserted and connected with the limiting groove 405 opened on the outer wall of the positioning rod 3. On the other hand, it is convenient for the pressing rod 402 to press down the positioning rod 3, avoiding the increase in the dynamic strength required for the pressing rod 402 to press down directly due to the friction between the limiting rod 404 and the positioning rod 3. Through the L-shaped setting of the limiting groove 405, the pressing rod 402 drives the limiting rod 404 to move along the inner cavity of the limiting groove 405 by first rotating, so that the limiting rod 404 moves to the vertical inner cavity range of the limiting groove 405. Thus, when the position of the pressing rod 402 is lowered, the resistance of the limiting rod 404 to the downward movement of the positioning rod 3 can be reduced. While ensuring the stable insertion use of the positioning rod 3, the flexibility and effectiveness of the separation of the positioning rod 3 from the upper die 1 are also improved.

[0028] Fixing structures 5 are symmetrically arranged on the outer wall of the mounting cylinder 401. The fixing structures 5 include fixing plates 501, fixing rods 502, and fixing grooves 503. The fixing plates 501 are fixedly arranged on the outer wall of the mounting cylinder 401. The fixing grooves 503 are opened at the top of the upper die 1. The fixing rods 502 are inserted between the fixing plates 501 and the fixing grooves 503.

[0029] As Figure 2 shown, the top of the fixing plate 501 is penetrated by the bottom end of the fixing rod 502. The fixing rod 502 is threadedly inserted into the inner cavity of the fixing groove 503. By rotating the fixing rod 502, the fixing rod 502 can be fixedly connected with the fixing groove 503. At the same time, the fixing rod 502 is T-shaped and can gradually squeeze the bottom end of the fixing plate 501 while rotating, so as to fix the position of the fixing plate 501, and thus also fix the position of the mounting cylinder 401. Furthermore, the mounting cylinder 401 can be disassembled and assembled according to the needs of use. Therefore, the replacement and disassembly of the pressing structure 4 can be carried out without affecting the mold, improving the flexibility of the replacement and disassembly of the pressing structure 4.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
