Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, specifically a 1600-ton hydraulic press for one-time molding of a Sichuan-shaped flat pallet by molding Background Art

[0002] The bottom of the Sichuan-shaped flat pallet is in the shape of three crossbeams, which is basically the same as the Chinese character 'Chuan'. On the one hand, it is convenient for everyone to select and view plastic pallets, and on the other hand, it is also for unified management. Therefore, in the unified name of the national standard, it is named the Chuan-shaped pallet.

[0003] A hydraulic press with a buffer structure described in the patent with the patent announcement number CN 220864828 U includes a base. A hydraulic mechanism is arranged on the top of the base, and a buffer mechanism is arranged inside the base. The buffer mechanism includes a buffer plate, the buffer plate is slidably connected inside the base, a buffer rod is fixedly installed on the top of the buffer plate, the buffer rod penetrates the top wall of the base, and a primary buffer component and a secondary buffer component are arranged between the buffer plate and the inner bottom wall of the base. The utility model relates to the technical field of hydraulic presses; for this hydraulic press with a buffer structure, when a brittle object breaks, the buffer plate quickly moves downward under the action of the huge force of the upper pressing plate above, and the moving plate also quickly moves downward. At this time, the non-Newtonian fluid will block the quickly moving moving plate and absorb the force generated by the pressing plate, so that the pressing plate will not quickly impact the lower hydraulic platform, thus realizing the buffering and protection of the pressing plate. However, this device lacks a demoulding structure, and manual demoulding is required, making the device highly dangerous.

[0004] Based on this, a 1600-ton hydraulic press for one-time molding of a Sichuan-shaped flat pallet by molding is now provided, which can eliminate the disadvantages of the existing device. Summary of the Utility Model

Through the above arrangement, the hydraulic mechanism 400 can fit the upper mold 500 and the lower mold 600 along the limiting slide bar 200, and the lower mold 600 can be separated and closed under the action of the sliding structure 700, so as to facilitate demolding after processing.

[0024] In one embodiment, Figure 1 As shown, the hydraulic mechanism 400 includes a hydraulic cylinder 401, a hydraulic piston rod 402 and a hydraulic piston plate 403. The hydraulic cylinder 401 is arranged on the top plate 300. The lower end of the hydraulic cylinder 401 is provided with a hydraulic piston rod 402. The lower end of the hydraulic piston rod 402 is connected to the hydraulic piston plate 403. The lower end of the hydraulic piston plate 403 is fixedly connected to the upper mold 500. Through the above arrangement, the upper mold 500 can follow the hydraulic piston plate 403 to move down to fit with the lower mold 600, and under the strong hydraulic action, it is guaranteed that the product is formed in one time and the qualified rate is improved.

[0025] In one embodiment, Figure 3As shown, the sliding structure 700 includes a slider 701, a slide rail 702, a screw 703 and a first drive motor 704. The slider 701 is arranged at the lower end of the lower mold 600 and is slidably arranged on the slide rail 702. The slide rail 702 is arranged in the base 100. The screw 703 passes through the slider 701 and is arranged on both sides of the slide rail 702. The output end of the first drive motor 704 is connected to the input end of the screw 703. Through the above arrangement, the first drive motor 704 drives the screw 703 to rotate, so that the slider 701 and the lower mold 600 connected thereto slide left and right, thereby controlling the formation and disintegration of the injection cavity.

[0026] In one embodiment, Figure 2 As shown, the ejection device 800 includes a protective shell 801, a second drive motor 802, a gear 803, a rack 804 and an ejection block 805. The protective shell 801 is arranged at the upper end of the base 100, and the second drive motor 802 is arranged in the protective shell 801. The input end of the gear 803 is connected to the output end of the second drive motor 802. The rack 804 is arranged below the gear 803. The end of the rack 804 close to the lower mold 600 is provided with an ejection block 805. Through the above arrangement, after the product is injection molded, the second drive motor 802 can drive the gear 803 to rotate, thereby driving the push rod 804, so that the ejection block 805 can push the product out. Example 2

[0027] In one embodiment, Figure 2 A roller 807 is provided at the lower end of the rack, and a slide groove 806 is provided at a position opposite to the roller 807 on the base. Through the above arrangement, the rack 804 can move freely on the base 100.

[0028] In one embodiment, Figure 1 As shown, a sliding sleeve 404 is provided on the hydraulic piston plate 403 at a position opposite to the limiting slide bar 200. Through the above arrangement, the friction between the hydraulic piston plate 403 and the limiting slide bar 200 can be reduced.

[0029] In one embodiment, Figure 1 As shown, an inclined plate 101 is provided on one end of the base 100 away from the ejection device 800. Through the above arrangement, the product can slide off the inclined plate 101 to avoid product damage due to height difference.

[0030] In one embodiment, Figure 1 As shown, an injection port 102 is provided on the side wall of the lower mold 600. Through the above arrangement, the injection pipe can be injected through the injection port 102, and the hot melt plastic is contaminated due to exposure to the air.

[0031] The above embodiment discloses a 1600-ton hydraulic press for molding a Sichuan-shaped flat pallet in one step. When the hydraulic press is working, the lower mold 600 is driven to move by the screw 703 driven by the first drive motor 704. When the lower mold 600 is closed, the upper mold 500 moves down under the drive of the hydraulic mechanism 400, and fits with the lower mold 600 to form an injection cavity, and then injection is performed by the injection port 102 set on the lower mold 600. When the product is cooled and formed, the upper mold 500 moves up under the action of the hydraulic mechanism 400, and the lower mold 600 is separated under the action of the sliding structure 700, and finally driven by the second drive motor 802, the ejection block 805 ejects the product and slides down along the inclined plate 101 to complete automatic demolding.
