Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic forming, in particular to a 2000-ton one-time molding hydraulic press for forming nine-angle flat pallets. Background Art

[0002] The nine-corner flat pallet is flexibly used in many industries due to its light weight and good load-bearing capacity. The nine-corner pallet has good operability and long service life. The nine foot piers of the nine-corner pallet are hollow cabin structures, which have good resistance to impact. At the same time, it is light in weight and can be folded when not in use, saving storage space. However, most of the processing devices on the market currently use manual fabrication and demoulding, which makes the processing process more dangerous.

[0003] Based on this, we now provide a 2000-ton one-time molding nine-angle flat pallet hydraulic press, which can eliminate the disadvantages of the existing device. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] In one embodiment, Figure 1-Figure 4As shown, a 2000-ton hydraulic press for molding nine-angle flat pallets in one step comprises a base 100, a limiting guide rod 200 is provided at the upper end of the base 100, a hydraulic press 400 is provided at the upper end of the limiting guide rod 200, a pressing plate 300 is provided at the lower end of the hydraulic press 400, an upper mold 500 is provided at the lower end of the pressing plate 300, a lower mold 600 is also provided at the upper end of the limiting guide rod 200, a first ejection structure 700 is also provided at the upper end of the base 100, and a second ejection structure 601 is provided at the lower inner cavity of the lower mold 600. Through the above arrangement, the upper mold 500 arranged on the pressing plate 300 moves downward along the limiting guide rod 200 under the action of the hydraulic press 400, and forms an injection cavity for injection when it is in contact with the lower mold 600.

[0024] In one embodiment, Figure 2 As shown, the hydraulic press 400 includes a hydraulic housing 401, a hydraulic piston plate 402 and a hydraulic piston rod 403. The hydraulic housing 401 is arranged at the upper end of the limiting guide rod 200, the hydraulic piston plate 402 is arranged in the hydraulic housing 401, and the hydraulic piston rod 403 is arranged at the lower end of the hydraulic piston plate 402 and passes through the hydraulic housing 401 and is connected to the pressure plate 300. Through the above arrangement, the hydraulic piston plate 402 moves downward under the action of oil pressure and pushes the hydraulic piston rod 403 to make the upper mold 500 fit with the lower mold 600.

[0025] In one embodiment, Figure 3 As shown, the second ejection structure 601 includes a hydraulic plate 602 and ejector pins 603. The ejector pins 603 are arranged in an array on the hydraulic plate 602. Through the above arrangement, after the injection molding is completed, the hydraulic plate 602 can be driven upward by hydraulic pressure to drive the ejector pins 603 to eject the product.

[0026] In one embodiment, Figure 2 As shown, the first ejection structure 700 includes a mounting shell 701, a movable plate 702 and an ejection block 703. The mounting shell 701 is arranged at the upper end of the base 100, the movable plate 702 is arranged in the mounting shell 701, and the ejection block 703 is fixedly arranged on one side of the movable plate 702 and extends through the mounting shell 701. Through the above arrangement, after the injection molding is completed, the movable plate 702 is driven by hydraulic pressure to enable the ejection block 703 to eject the processed product onto the conveying device.

[0027] In one embodiment, Figure 1-Figure 4 As shown, an injection port 604 is also provided on the upper side wall of the lower mold 600. Through the above arrangement, when the device is working, an injection cavity is first formed and then injection is performed through the injection port 604, thereby reducing external pollution.

[0028] In one embodiment, Figure 4As shown, a mesh water cooling pipe 605 is also provided in the lower mold 600. Through the above arrangement, the mesh water cooling pipe 605 accelerates product cooling during operation of the device, thereby improving work efficiency and preventing damage to the product due to insufficient strength when it is ejected.

[0029] In one embodiment, Figure 1-Figure 4 The 2000-ton one-time molding nine-angle flat pallet hydraulic press shown is characterized in that a sliding sleeve 800 is provided on the pressing plate 300. Through the above arrangement, the wear of the pressing plate 300 when the limiting guide rod 200 moves up and down is reduced, thereby extending the service life of the equipment.

[0030] In one embodiment, Figure 1-Figure 4 As shown, the limiting guide rod 200 is arranged at each of the four corners of the base 100. Through the above arrangement, the pressing plate 300 maintains horizontal stability during the process of driving the upper mold 500 to move downward, thereby reducing the possibility of the mold being unable to align due to shaking.

[0031] The above embodiment discloses a 2000-ton hydraulic press for molding a nine-angle flat pallet in one step. When the device is working, the hydraulic press 400 provides downward pressure, so that the pressure plate 300 drives the upper mold 500 to move downward. When the upper mold 500 and the lower mold 600 are fitted to form an injection cavity, hot melt plastic is injected through the injection port 604. After the injection molding is completed, the product is quickly cooled by the mesh water cooling pipe 605, and finally the second ejection structure 601 ejects the product, and then the first ejection structure 700 ejects the product onto the conveying device to complete the assembly line operation, thereby saving labor and increasing safety.

[0032] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
