[0025] By adopting the above technical scheme, when the mold needs to be replaced, the jacking mechanism is driven to move downward and drive the mold to be replaced to descend. During the descent of the mold to be replaced, the clamping frame descends due to gravity and gradually opens and releases the clamping of the mold as the slide rail moves, and the mold to be replaced is recovered to the mold storage box; the sliding mechanism is controlled to drive the mold storage box to slide, thereby driving the new mold to slide to the bottom of the clamping mechanism, and driving the jacking mechanism under the new mold to drive the new mold to jack up; when the new mold is driven by the jacking mechanism, during the rising process, the new mold passes between the two lower clamping plates and supports the two upper clamping plates during the rising process, the jacking mechanism continues to drive the new mold to jack up, and then continues to drive the clamping frame to move up along the slide rail, and gradually clamps the mold during the upward movement, and completes the replacement of the mold when it is jacked to the top of the working area, effectively improving the efficiency of mold replacement and effectively solving the problem of difficult mold disassembly; In summary, the present application includes at least one of the following beneficial technical effects: 1.

DETAILED DESCRIPTION

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] The embodiment of the present application discloses a mold replacement device for a container plate forming machine and a mold replacement method thereof.

[0030] Reference Figures 1 to 3 , wherein the mold 4 replacement device for the container sheet forming machine comprises a machine body 1, a mounting seat 2 is arranged at the bottom of the machine body 1, a mold storage box 3 is arranged below the mounting seat 2, a plurality of molds 4 are arranged in an array in the mold storage box 3, a lifting mechanism 5 is arranged between each mold 4 and the mold storage box 3, the lifting mechanism 5 is used to lift the mold 4 in the mold storage box 3, a clamping mechanism 6 is arranged on the mounting seat 2, the clamping mechanism 6 is used to clamp the lifted mold 4, and a sliding mechanism 7 is arranged at the bottom of the mold storage box 3, the sliding mechanism 7 is used to adjust the position of the mold storage box 3 so that the mold 4 to be replaced corresponds to the clamping mechanism 6; The machine body 1 is also provided with a cutting cylinder, the output end of which is connected to a cutter rack 8 , on which a cutter 8 is provided. The cutting cylinder drives the cutter 8 to move downward, thereby cutting the plate in the mold 4 .

[0031] Reference Figure 3 and Figure 4The clamping mechanism 6 includes a workbench 61 arranged on the mounting seat 2, and a working area 62 is opened inside the workbench 61. Slide rails 63 are arranged on both sides of the working area 62. The two slide rails 63 are inclined, and the tops of the two slide rails 63 are inclined toward the inner side of the machine body 1. A clamping member 64 is slidably arranged on each slide rail 63. The two clamping members 64 gradually clamp the mold 4 when the mold 4 is continuously lifted. A tight member 66 is also arranged between the clamping member 64 and the mold 4. The tight member 66 is used to further enhance the clamping force of the clamping member 64 on the mold 4.

[0032] It should be noted that the inclined slide rail 63 enables the clamping member 64 on the slide rail 63 to gradually clamp the mold 4 during movement, so that the higher the mold 4 is lifted, the tighter the clamping mechanism 6 clamps it, effectively improving the overall stability of the device.

[0033] Reference Figure 4 The two clamping members 64 each include a sliding block 641 respectively arranged on the two slide rails 63, a connecting rod 642 is horizontally arranged on the side of each sliding block 641 away from the slide rail 63, and a clamping frame 643 is fixedly arranged at the other end of each connecting rod 642, and a horizontally arranged upper clamping plate 644 and a lower clamping plate 645 are respectively arranged at the upper and lower ends of the clamping frame 643.

[0034] Specifically, when there is no mold 4 clamped between the upper clamp 644 and the lower clamp 645, the sliding block 641 is at the bottom of the slide rail 63. When the mold 4 is lifted by the lifting mechanism 5, the mold 4 passes through the gap between the two lower clamps 645, and the mold 4 abuts against the two upper clamps 644 during the gradual lifting process, and drives the sliding block 641 to move upward along the slide rail 63. During the gradual upward movement of the module, the two clamping frames 643 gradually approach each other, and the two lower clamps 645 are gradually supported on the bottom of the mold 4.

[0035] It should be noted that the design of the upper clamp plate 644 and the lower clamp plate 645 is such that, during the lifting process of the mold 4, the mold 4 enters into the inner side of the two clamping frames 643 through the gap between the two lower clamp plates 645, and abuts against the two upper clamp plates 644 during the gradual lifting process, and drives the sliding block 641 to move upward along the slide rail 63, thereby realizing the gradual clamping of the mold 4 by the clamping member 64, further improving the overall stability of the device.

[0036] Reference Figure 4 A polytetrafluoroethylene block 65 is fixedly provided at the contact point between the lower clamping plate 645 and the mold 4 , and the polytetrafluoroethylene block 65 is used to increase the friction between the lower clamping plate 645 and the mold 4 .

[0037] Reference Figure 4Each tightening member 66 includes an arc-shaped abutment plate 661 arranged between the clamping frame 643 and the mold 4, and each arc-shaped abutment plate 661 is bent toward one side of the clamping frame 643, and a buffer spring 662 is fixedly arranged between each arc-shaped abutment plate 661 and the clamping frame 643.

[0038] During the process of the lifting mechanism 5 driving the new mold 4 to lift, the design of the arc-shaped abutment plate 661 enables the mold 4 to drive the arc-shaped abutment plate 661 to be squeezed toward the buffer spring 662, and the arc-shaped design enables the mold 4 to better abut against the outer wall of the arc-shaped abutment plate 661 during movement, thereby avoiding the arc-shaped abutment plate 661 from blocking the lifting of the mold 4. The reaction force of the buffer spring 662 drives the arc-shaped abutment plate 661 to abut against the mold 4, thereby achieving further clamping of the mold 4.

[0039] Reference Figure 3 The lifting mechanism 5 includes a lifting cylinder 51, which is fixedly arranged in the mold storage box 3, and the output end of the lifting cylinder 51 is fixedly connected to the bottom of the mold 4. It should be noted that two lifting cylinders 51 are arranged at the bottom of each mold 4, thereby effectively improving the stability of the mold 4 during the lifting process.

[0040] Reference Figure 1 , Figure 3 and Figure 5 The sliding mechanism 7 includes two sliding rails 71 relatively arranged at the bottom of the mold storage box 3 and a driving member 72 for driving the mold storage box 3 to slide along the sliding rails 71. The mold storage box 3 is slidably arranged on the sliding rails 71, and the driving member 72 is used to drive the mold storage box 3 to slide along the sliding rails 71, so as to facilitate the adjustment of the position of the mold 4.

[0041] Specifically, the driving member 72 includes two mounting frames 721 disposed on both sides of the sliding track 71, and driving screws 722 are rotatably disposed on the two mounting frames 721. A driving motor 723 is disposed on one side of the two mounting frames 721. The rotating shaft of each driving motor 723 is transmission-connected with the corresponding driving screw 722, and the two driving screws 722 are respectively threadedly connected with the two sides of the bottom of the mold storage box 4. The driving screws 722 can effectively improve the accuracy of the mold storage box 3 during the lifting process, and ensure that the clamping mechanism 6 can accurately clamp the mold 4.

[0042] The implementation principle of the mold replacement device for a container sheet forming machine in the embodiment of the present application is as follows: when the mold 4 needs to be replaced, the lifting cylinder 51 is driven to move downward and drive the mold 4 to be replaced to descend. During the descent of the mold 4 to be replaced, the clamping frame 643 descends due to gravity and gradually opens and releases the clamping of the mold 4 as the slide rail 63 moves, and the mold 4 to be replaced is recovered to the mold storage box 3; The driving motor 723 is controlled to drive the driving screw 722 to rotate, thereby driving the mold storage box 3 to slide along the sliding track 71, thereby driving the new mold 4 to slide to the bottom of the clamping frame 643, and driving the lifting cylinder 51 under the new mold 4 to drive the new mold 4 to lift upward; When the new mold 4 is driven by the lifting cylinder 51, during the rising process, the new mold 4 passes through the two lower clamps 645 and supports the two upper clamps 644 during the rising process. The lifting cylinder 51 continues to drive the new mold 4 to be lifted, and then continues to drive the clamping frame 643 to move upward along the slide rail 63, and gradually clamps the mold 4 during the upward movement. The replacement of the mold 4 is completed when it is lifted to the top of the working area 62.

[0043] The embodiment of the present application also discloses a mold replacement method of a mold replacement device for a container plate forming machine.

[0044] The mold replacement method of the mold replacement device for the container plate forming machine comprises the following steps: S1, the lifting mechanism 5 under the old mold 4 drives the old mold 4 to move downward and recycle it into the mold storage box 3; S2, the sliding mechanism 7 drives the mold storage box 3 to slide, drives the new mold 4 to slide to the bottom of the clamping mechanism 6, and the lifting mechanism 5 under the new mold 4 drives the new mold 4 to lift upward; S3, the new mold 4 is driven by the lifting mechanism 5 to continue to rise, the new mold 4 passes between the two lower clamping plates 645 and holds up the two upper clamping plates 644 during the rising process, the lifting mechanism 5 drives the new mold 4 to move up and drives the clamping frame 643 to move up along the slide rail 63, and the clamping frame 643 gradually approaches the new mold 4 and clamps the new mold 4 during the upward movement along the slide rail 63; S4, the lifting mechanism 5 of the new mold 4 lifts the new mold 4 to the top of the working area 62 and keeps it still, completing the replacement of the mold 4.

[0045] The implementation principle of the mold replacement method of the mold replacement device for a container plate forming machine in the embodiment of the present application is as follows: when the mold 4 needs to be replaced, the lifting mechanism 5 is driven to move downward and drive the mold 4 to be replaced to descend. During the descent of the mold 4 to be replaced, the clamping frame 643 is lowered by gravity and gradually opens and releases the clamping of the mold 4 as the slide rail 63 moves, and the mold 4 to be replaced is recovered to the mold storage box 3; Control the sliding mechanism 7 to drive the mold storage box 3 to slide, thereby driving the new mold 4 to slide to the bottom of the clamping mechanism 6, and drive the lifting mechanism 5 under the new mold 4 to drive the new mold 4 to lift upward; When the new mold 4 is driven by the lifting mechanism 5, during the rising process, the new mold 4 passes through the two lower clamps 645 and supports the two upper clamps 644 during the rising process. The lifting mechanism 5 continues to drive the new mold 4 to be lifted, and then continues to drive the clamping frame 643 to move upward along the slide rail 63, and gradually clamps the mold 4 during the upward movement, and completes the replacement of the mold 4 when it is lifted to the top of the working area 62.
