[0026] 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 scope of protection of the present utility model.

[0027] Please see Figures 1-8 As shown, a multi-functional press includes a base 1, a support frame 2 fixedly connected to the top of the base 1, a hydraulic rod 3 fixedly connected to the top of the support frame 2, the bottom end of the hydraulic rod 3 passing through the support frame 2, and a push plate 4 fixedly connected to the bottom end of the hydraulic rod 3; a pop-out mechanism is provided at the top of the base 1, and a replacement structure is provided on the push plate 4.

[0028] The replacement structure includes a pressure plate 58, which is located at the bottom of the push plate 4. A slide rail 59 is fixedly connected to the top of the pressure plate 58, and the slide rail 59 is slidably connected to the push plate 4. A movable cavity 61 is opened at the top of the push plate 4, and a limiting block 62 is sleeved inside the movable cavity 61. A second spring 63 is also installed inside the movable cavity 61. The top of the limiting block 62 engages with a limiting groove 64, which is opened on the slide rail 59. A transmission groove 67 is opened on one side of the limiting groove 64, and the transmission groove 67 is connected to the limiting groove 64. A transmission gear 69 is rotatably connected at the center of the transmission groove 67, and the front and rear sides of the transmission gear 69 mesh with each other. It has two sets of racks 68, which are slidably connected inside the transmission groove 67. The top end of the second spring 63 is fixedly connected to the bottom end of the limiting block 62, and the bottom end of the second spring 63 is fixedly connected to the inner wall of the movable cavity 61. The top end of the transmission gear 69 passes through the slide rail 59 and extends to the outside of the slide rail 59. The top end of the transmission gear 69 is fixedly connected to the knob 71, and the outside of the knob 71 is provided with anti-slip texture. A torsion spring 70 is provided between the top end of the transmission gear 69 and the inner wall of the transmission groove 67. The top end of the torsion spring 70 is fixedly connected to the inner wall of the transmission gear 69, and the top end of the torsion spring 70 is fixedly connected to the top end of the transmission gear 69.

[0029] When replacing the pressure plate 58 during operation, first turn the knob 71 to drive the fixedly connected transmission gear 69 to rotate synchronously. The rotation of the transmission gear 69 drives the fixedly connected torsion spring 70 to twist, causing the torsion spring 70 to undergo elastic deformation. When the transmission gear 69 rotates, it drives the meshing rack 68 to move, so that the rack 68 abuts against the inclined surface on the side of the limiting block 62 and squeezes the limiting block 62. Under the action of the squeezing force, the limiting block 62 moves into the interior of the movable cavity 61, releasing the state of being locked with the limiting block 62. At this time, pull the pressure plate 58 forward to drive the slide rail 59 to move synchronously, so that the slide rail 59 is separated from the push plate 4, and the pressure plate 58 can be removed.

[0030] When installing the pressure plate 58, simply align the slide rail 59 with the push plate 4, and then insert the slide rail 59 into the push plate 4. When the slide rail 59 is inserted into the push plate 4, the bottom end of the slide rail 59 presses against the inclined surface on the front side of the limiting block 62, causing the limiting block 62 to enter the interior of the movable cavity 61 under the pressure. This causes the second spring 63 to be compressed and undergo elastic deformation. When the slide rail 59 is inserted to the limit of the push plate 4, the limiting groove 64 on the slide rail 59 aligns with the limiting block 62. At this time, the slide rail 59 no longer presses against the limiting block 62. Under the restoring force of the second spring 63, the limiting block 62 returns to its original position and is inserted into the limiting groove 64, engaging with the limiting groove 64, thus fixing the pressure plate 58 and the slide rail 59.

[0031] The restoring force of the torsion spring 70 enables the transmission gear 69 to automatically rotate back to its original position after the external force disappears. At the same time, the rack 68 that meshes with the transmission gear 69 also moves back to its original position as the transmission gear 69 rotates, thus preventing the limit block 62 from being blocked when the pressure plate 58 is installed again.

[0032] Furthermore, a sliding block 65 is fixedly connected to one side of the bottom end of the limiting block 62, and the sliding block 65 is slidably connected to the inside of the sliding groove 66, which is opened on one side of the inner wall of the movable cavity 61.

[0033] During operation, when the limiting block 62 moves, the sliding block 65, which is fixedly connected to the limiting block 62, slides synchronously inside the sliding groove 66. The combined action of the sliding block 65 and the sliding groove 66 limits the movement distance of the limiting block 62, preventing the limiting block 62 from moving excessively and coming out of the active cavity 61 under the restoring force of the second spring 63.

[0034] Furthermore, the pop-out mechanism includes a storage cavity 51, which is located at the top of the base 1. A connecting post 52 is fixedly connected inside the storage cavity 51. A first spring 53 is installed inside the connecting post 52, and a movable rod 54 is sleeved inside the connecting post 52. The top end of the first spring 53 is fixedly connected to the bottom end of the movable rod 54, and the bottom end of the first spring 53 is fixedly connected to the inner wall of the connecting post 52. A sliding plate 55 is fixedly connected to the top end of the movable rod 54. A slider 56 is fixedly connected to one side of the inner wall of the connecting post 52. The slider 56 is slidably connected inside the sliding groove 57, which is located on one side of the movable rod 54.

[0035] During operation, when the hydraulic rod 3 drives the push plate 4 to press the pressure plate 58 downward, the pressure plate 58 presses the material placed on the top plate 55, causing the material to move downward under the pressure. This also causes the top plate 55 to move synchronously into the receiving cavity 51. The movable rod 54, which is fixedly connected to the top plate 55, also moves into the connecting column 52 along with the movement of the top plate 55, pressing the first spring 53. After the material is formed, the pressure on the top plate 55 disappears. At this time, the movable rod 54 moves upward under the action of the restoring force of the first spring 53, and synchronously pushes the material placed on the top plate 55 upward through the top plate 55, causing the material to separate from the surface of the base 1, so that the operator can easily remove the material from the device.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
