SPECIFIC EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying 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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1

[0026] Please refer to Figures 1 - 4, in the embodiment of the present utility model, a hydraulic press for a molded flat nine-pin one-piece forming tray includes an upper mold 1 and a lower mold 2. A transfer block 3 is fixedly connected to the top of the upper mold 1. A top plate 4 is movably abutted against the top of the transfer block 3. Hydraulic rods 5 are fixedly connected to both sides of the top of the top plate 4, and the output ends of the hydraulic rods 5 are slidably connected to the inside of the top plate 4. The output ends of the hydraulic rods 5 are fixedly connected to the top of the transfer block 3. A base 6 is fixedly connected to the bottom of the lower mold 2. Slide rods 7 are fixedly connected to the periphery of the top of the base 6, and the outer walls of the slide rods 7 are fixedly connected to the inside of the top plate 4. A water tank 8 is fixedly connected to the bottom of the base 6. A plurality of mold holes 9 are provided in the top of the lower mold 2. A pressing component for pressing the tray blank is provided at the bottom of the upper mold 1. A limiting component for limiting the tray blank is provided on one side of the lower mold 2. Clamping components for clamping the tray blank are provided on both sides of the lower mold 2. A cooling component for cooling the tray blank is provided on the other side of the lower mold 2.

[0027] In one embodiment, as Figure 2 and Figure 3 shown, the pressing component includes a threaded hole 10 opened at the bottom of the upper mold 1. A pressing column 11 is threadedly connected to the threaded hole 10. By rotating the pressing column 11, it rotates at the threaded hole 10, which is convenient for replacement. Pressing columns 11 with different diameters can be installed according to different requirements.

[0028] In one embodiment, as Figure 2 shown, the limiting component includes a motor 12. The output end of the motor 12 is fixedly connected to a threaded rod 13. The end of the threaded rod 13 away from the motor 12 is rotatably connected to one side of the lower mold 2. The threaded rod 13 is threadedly connected to the inside of a first limiting plate 14. A limiting rod 15 is slidably connected to the inside of the first limiting plate 14. One side of the limiting rod 15 is fixedly connected to one side of the lower mold 2. The side of the limiting rod 15 away from the lower mold 2 is fixedly connected to a second limiting plate 16. By starting the motor 12, it drives the threaded rod 13 to rotate. The threaded rod 13 drives the first limiting plate 14 to move. Since the limiting rod 15 is also slidably connected to the inside of the first limiting plate 14, the first limiting plate 14 can only move horizontally between the second limiting plate 16 and the lower mold 2.

[0029] In one embodiment, as Figure 2 and Figure 3As shown, the clamping assembly includes clamping plates 17, which are arranged on both sides of the lower mold 2. A number of tension springs 18 are fixedly connected to the side of the clamping plates 17 close to the lower mold 2, and the other ends of the tension springs 18 are fixedly connected to one side of the lower mold 2. At both ends of the side of the clamping plates 17 close to the lower mold 2, support columns 19 are fixedly connected. The other ends of the support columns 19 are slidably connected inside the lower mold 2. By applying a force to the clamping plates 17 to make them move away from the lower mold 2, then placing a metal tray on the lower mold 2 and canceling the force on the clamping plates 17, the tension springs 18 will apply a pulling force to the clamping plates 17 to make them close to the lower mold 2, so that metal tray blanks of different sizes can be fixed. The support columns 19 can support the clamping plates 17 and the tension springs 18 so that they will not fall off.

[0030] In one embodiment, as Figure 1 shown, the cooling assembly includes a water pump 20. The bottom of the water pump 20 is fixedly connected to the top of the lower mold 2. A water suction pipe 21 is installed at the hydraulic input end of the water pump 20, and the other end of the water suction pipe 21 is arranged inside the water tank 8. A number of water outlet pipes 22 are installed at the hydraulic output end of the water pump 20. By pumping water into the water tank 8 through the water suction pipe 21, and then conveying it to the water outlet pipes 22 through the water pump 20, and then spraying the lower mold 2, the heated plastic can be cooled after pressing, so that it can be fixed. Embodiment 2

[0031] In one embodiment, as Figure 2 shown, the end of the pressing column 11 away from the upper mold 1 is arc-shaped, which is convenient for the pressing column 11 to perform pressing.

[0032] In one embodiment, as Figure 3 shown, the upper mold 1 and the lower mold 2 fit each other, and the centers of the upper mold 1 and the lower mold 2 are on the same axis. The perfect fit of the upper mold 1 and the lower mold 2 ensures that they are on the same axis, so that the extrusion will not go wrong.

[0033] In one embodiment, as Figure 2 and Figure 3 shown, the diameter of the pressing column 11 is smaller than the diameter of the die hole 9, and the pressing column 11 is matched with the die hole 9, which is convenient for the pressing column 11 to press the tray blank into the die hole 9.

[0034] The working principle of the present utility model is as follows: In the above-mentioned embodiment, a hydraulic press for a molded flat nine-foot one-piece pallet is disclosed. A metal pallet blank is placed on the lower die 2, and then the motor 12 is started to drive the threaded rod 13 to rotate. The threaded rod 13 drives the first limiting plate 14 to move. Since the limiting rod 15 is also slidably connected inside the first limiting plate 14, the first limiting plate 14 can only move horizontally between the second limiting plate 16 and the lower die 2, thereby limiting the metal pallet blank. Subsequently, by applying a force to the clamping plate 17, the clamping plate 17 is moved away from the lower die 2. Then, a metal pallet blank is placed on the lower die 2, and the force applied to the clamping plate 17 is cancelled. The tension spring 18 will apply a pulling force to the clamping plate 17 to make it close to the lower die 2, so that metal pallet blanks of different sizes can be fixed. The support column 19 can support the clamping plate 17 and the tension spring 18 so that they will not fall. Subsequently, through the hydraulic rod 5, the upper die 1 presses the metal pallet blank on the lower die 2. If a heated plastic pallet blank is placed on the lower die 2, after the pressing is completed, it can be conveyed to the water outlet pipe 22 through the water pump 20, and then the plastic pallet blank on the lower die 2 is sprayed to be cooled and fixed. By rotating the pressing column 11, it rotates at the threaded hole 10, which is convenient for replacement, and pressing columns 11 with different diameters can be installed according to different requirements.

[0035] As described above, the above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
