[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 A mold for forming a RV storage box includes a base 1, a workbench 2 fixedly connected to the upper surface of the base 1, a support rod 3 fixedly connected to the upper surface of the workbench 2, a sliding beam 4 slidably connected to the outer wall surface of the support rod 3, a crossbeam 5 fixedly connected to one side surface of the support rod 3, a hydraulic device 6 fixedly connected to one side surface of the crossbeam 5, an upper mold 7 fixedly connected to the lower surface of the sliding beam 4, and a cooling mechanism 8 provided on the upper surface of the workbench 2; the cooling mechanism 8 includes a cooling device and a positioning device.

[0017] In this embodiment, the positioning device includes a lower mold 801, which is fixedly connected to one side surface of the worktable 2. A groove 802 is formed on one side surface of the lower mold 801, and a circular groove 803 is formed on one side surface of the groove 802. A rotating shaft 805 is fixedly connected to the inner wall surface of the groove 802, and a rotating plate 806 is rotatably connected to the outer wall surface of the rotating shaft 805. A limiting block 810 is fixedly connected to one side surface of the groove 802. With the rotating shaft 805, the limiting block 810 and the rotating plate 806, the rotating plate 806 rotates along the rotating shaft 805 during use. The limiting block 810 restricts the rotating plate 806 from excessive rotation, ensuring that the rotating plate 806 is at a suitable limiting angle, and preventing the rotating plate 806 from shaking during mold contact, thereby affecting the stability of the internal cooling pipe 809.

[0018] Furthermore, the cooling device includes a circular hole 804, which is formed on the inner wall surface of the circular groove 803. A circular rod 807 is slidably connected to the inner wall of the circular hole 804. A clamp 808 is fixedly connected to one side surface of the circular rod 807. A cooling pipe 809 is slidably connected to the inner side of the clamp 808. A spring 811 is slidably connected to the outer wall surface of the circular rod 807. With the cooling pipe 809, when the mold temperature rises during use, water passes through the cooling pipe 809 to carry away the heat, effectively shortening the molding cycle.

[0019] Furthermore, two grooves 802 of the same size are provided and are symmetrically distributed along the central axis of the lower mold 801. The inner wall size of the groove 802 matches the outer wall size of the rotating plate 806. Through the arrangement of the groove 802 and the rotating plate 806, the rotating plate 806 and the groove 802 form a sealed space during use. Due to the existence of the sealed environment, heat cannot diffuse to the surrounding air and can only be quickly transferred to the cooling pipe 809 through heat conduction. This allows the cooling pipe 809 to absorb a large amount of heat in a short time, greatly improving the cooling efficiency.

[0020] Furthermore, the outer wall dimensions of the cooling pipe 809 are adapted to the inner wall dimensions of the circular groove 803, and the inner wall dimensions of the clamp 808 are adapted to the outer wall dimensions of the cooling pipe 809. Through the arrangement of the clamp 808, the cooling pipe 809, and the circular groove 803, a stable connection can be formed during use because the outer wall dimensions of the cooling pipe 809 are adapted to the inner wall dimensions of the circular groove 803. When the circular rod 807 moves the clamp 808, the cooling pipe 809 can be precisely embedded into the inner wall of the clamp 808, achieving seamless connection, reducing shaking, and improving the stability of the mechanism.

[0021] In addition, the outer wall size of the round rod 807 matches the inner wall size of the round hole 804. The round groove 803 is provided with two sets of the same size, and each set has two of the same size. The inner wall size of the round groove 803 is adapted to the outer wall size of the spring 811. Through the setting of the round rod 807 and the round hole 804, the round rod 807 slides along the round hole 804 during use. The round hole 804 restricts the round rod 807, ensuring that the clamp 808 and the round groove 803 always remain parallel to each other, thus improving the stability of the cooling pipe 809.

[0022] It is worth noting that there are two cooling pipes 809 of the same size, and the inner wall is filled with water. The limiting block 810 and the groove 802 are distributed in parallel. With the setting of the cooling pipes 809, when in use, the two cooling pipes 809 of the same size and filled with water absorb the heat of the upper mold 7 through the cooling water, so as to achieve efficient cooling.

[0023] During use, the spring 811 is in its naturally extended state, using its own elastic potential energy to push the clamp 808 and drive the round rod 807 to slide precisely along the inner wall of the round hole 804. Thanks to the precise fit between the round hole 804 and the round rod 807, this sliding process is smooth and without deviation, allowing the clamp 808 to firmly and evenly hold the cooling pipe 809, laying the foundation for subsequent efficient cooling. At this time, the lower mold 801 is tightly fixed to the worktable 2 with high-strength bolts to ensure stability during the molding process. The rotating plate 806 remains in its initial position around the rotating shaft 805, and the limiting block 810 strictly limits the rotation range of the rotating plate 806 to prevent it from affecting the positioning accuracy of the mold due to excessive rotation. When the production command is issued, the hydraulic device 6 starts, and the strong hydraulic power pushes the sliding beam 4 to move smoothly downward, thereby driving the upper mold 7 to slowly descend. During this process, symmetrically distributed rotating plates 806 rotate out of grooves 802, and with their perfectly matched dimensions, they fit tightly against the side walls of the upper mold 7, providing precise guidance and stable support for the downward movement of the upper mold 7. As the molds gradually approach and eventually close, they fit together seamlessly to form a complete molding cavity, like precise puzzle pieces perfectly aligned. Then, the injection molding equipment begins operation, injecting high-temperature molten plastic into the cavity with precise pressure and flow rate. During the filling process, the mold's gating system plays a crucial role, ensuring that the molten plastic fills every corner evenly and quickly, guaranteeing precise molding results for every part of the storage box. Once the cavity is filled, the cooling process begins. The water in the cooling pipe 809 serves as a highly efficient cooling medium. Thanks to the close fit between the cooling pipe 809 and the mold, as well as the stable clamping effect of the clip 808, heat can be quickly and efficiently transferred from the mold and the storage box blank to the water in the cooling pipe 809. As the cooling water circulates continuously, the mold temperature drops rapidly, and the storage box blank gradually solidifies during the uniform cooling process. Every detail is precisely solidified under the action of low temperature, ensuring the dimensional accuracy and appearance quality of the final product. After the storage box has cooled and solidified, the hydraulic device 6 starts to work in reverse, using hydraulic thrust to move the sliding beam 4 upward, thereby smoothly demolding the upper mold 7. At this point, a complete storage box is presented on the lower mold 801, awaiting subsequent removal and inspection. If the cooling pipe 809 is damaged or requires maintenance or replacement during use, the operator only needs to gently rotate the rotating plate 806 to move it out of its limited position, exposing the previously hidden groove 802. Then, by pulling the round rod 807, the clamp 808 gradually moves away from the cooling pipe 809 under the force, while the spring 811 contracts along the round groove 803, releasing the clamping force on the cooling pipe 809. The unrestricted cooling pipe 809 can then be easily removed. After replacing it with a new cooling pipe 809, the mold structure is restored by following the reverse operation steps. The entire maintenance process is convenient and efficient, without affecting the continuous production of the mold. Through such a rigorous and efficient process, the entire usage process of the RV storage box molding mold is completed.
