[0002] A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press is generally composed of three parts: the machine (host), the power system and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses. They are often used in pressing processes and pressing forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, thin plate drawing, powder metallurgy, pressing, etc.

[0003] However, many hydraulic presses nowadays, when in use, will cause the workpiece to adhere to the pressing plate under the pressure of the pressing plate due to the downward force applied, making it impossible for the pressing plate to be separated from the workpiece normally, requiring manual processing, which brings unnecessary trouble.

[0004] In view of this, the utility model proposes a four-column servo rapid extrusion hydraulic press. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0025] The preferred embodiment of the four-column servo rapid extrusion hydraulic press provided by the utility model is as follows: Figures 1 to 5 As shown: a four-column servo rapid extrusion hydraulic press comprises a base 1, the top of the base 1 is fixedly connected to a support column 2, the top of the support column 2 is fixedly connected to a top plate 3, the bottom of the top plate 3 is fixedly connected to a hydraulic cylinder 4, the output end of the hydraulic cylinder 4 is fixedly connected to a lifting plate 5 slidably connected to the support column 2, the bottom of the lifting plate 5 is fixedly connected to a pressing plate 6, and the side of the pressing plate 6 is fixedly connected to an anti-stuck material mechanism 7.

[0026] In this embodiment, the anti-stuck material mechanism 7 includes a transmission mechanism 71 and a pushing mechanism 72 . By providing the anti-stuck material mechanism 7 , the object adhered to the pressing plate 6 can be separated from the bottom of the pressing plate 6 .

[0027] In this embodiment, the transmission mechanism 71 includes an electric push rod 711, a connecting plate 712, a slide plate 713 and a transmission plate 714. By setting the transmission mechanism 71, the transmission mechanism 71 can apply power to the descent of the push rod 723.

[0028] In this embodiment, the electric push rod 711 is fixedly connected to the right side of the pressure plate 6, the output end of the electric push rod 711 is fixedly connected to a connecting plate 712, the top of the connecting plate 712 is fixedly connected to a slide plate 713 that is slidably connected to the pressure plate 6, and the top of the connecting plate 712 is fixedly connected to a transmission plate 714.

[0029] In this embodiment, the pushing mechanism 72 includes a movable plate 721, a push plate 722 and a push rod 723. By setting the pushing mechanism 72, the pushing mechanism 72 can control the push rod 723 to descend and push the material to avoid the material from sticking to the push rod 723.

[0030] In this embodiment, the movable plate 721 is rotatably connected to the surface of the transmission plate 714, and the surface of the movable plate 721 is rotatably connected to a push plate 722. The bottom of the push plate 722 is fixedly connected to a push rod 723 that is slidably connected to the pressure plate 6. When the transmission plate 714 moves to the left, it pushes the movable plate 721 to rotate to the left. When the movable plate 721 rotates, it pushes the push plate 722 downward, causing it to drive the push rod 723 to descend. At this time, the push rod 723 pushes the object downward to separate it from the pressure plate 6. Example 2

[0031] On the basis of Example 1, the preferred embodiment of the four-column servo rapid extrusion hydraulic press provided by the utility model is as follows: Figures 1 to 5 As shown: a mold 8 is placed inside the base 1, blocks 9 are fixedly connected on both sides of the base 1, embedded plates 11 are slidably connected inside the two groups of blocks 9, mounting plates 10 embedded in the mold 8 are fixedly connected to the inner walls of the two groups of embedded plates 11, screw holes 13 are opened on the tops of the two groups of embedded plates 11, and screws 12 embedded in the screw holes 13 are threadedly connected to the internal threads of the blocks 9.

[0032] In this embodiment, the mounting plate 10 is in a tightly fitted state with the inner wall of the mold 8, and the embedded plate 11 is fixed inside the block 9 by means of screws 12. The embedded plate 11 is embedded inside the block 9, and then the screws 12 are screwed into the block 9 and embedded into the screw holes 13. After tightening the screws 12, the embedded plate 11 will be fixed inside the block 9, thereby fixing the mounting plate 10 inside the mold 8.

[0033] The working principle and usage process of the utility model are as follows: first, when the mold 8 needs to be installed, the mold 8 can be placed inside the base 1, and then the mounting plate 10 can be inserted into the mold 8, and the embedding plate 11 can be embedded in the block 9, and then the screw 12 can be screwed into the block 9, and the screw 12 can be embedded into the screw hole 13. After tightening the screw 12, the embedding plate 11 will be fixed inside the block 9, so that the mounting plate 10 is fixed inside the mold 8, and the mold 8 is clamped by the mounting plate 10. When the mold 8 needs to be disassembled, it is only necessary to take out the mounting plate 10 from the inside of the mold 8 to quickly realize the disassembly of the mold 8.

[0034] By setting the pushing rod 723, when the pressing plate 6 has finished processing the object, in order to prevent the object from sticking to the bottom of the pressing plate 6 under the action of pressure, at this time, the electric pushing rod 711 can be turned on to pull the connecting plate 712. After the connecting plate 712 moves, it will drive the sliding plate 713 to slide on the surface of the pressing plate 6 and drive the transmission plate 714 to move together. When the transmission plate 714 moves to the left, it will push the movable plate 721 to rotate to the left. When the movable plate 721 rotates, it will push the pushing plate 722 downward, so that it drives the pushing rod 723 to descend. At this time, the pushing rod 723 will push the object downward to separate it from the pressing plate 6.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
