Sliders 605 are connected to the left and right sides of the movable mold base 601, and limit piles 606 are vertically installed symmetrically on the left and right sides of the bottom of the movable mold base 601. The bottom surface structure of the connecting frame 504 matches the top surface structure of the connecting seat 602, and the connecting frame 504 and the connecting seat 602 are fixed by bolts. The forming mold 7 is threadedly connected to the connecting bolt 604. By installing a connecting frame 504 at the bottom end of the hydraulic cylinder 503, the movable mold base 601 is structurally combined and docked with the connecting seat 602 at the top with the use of bolts, so that the entire pressing assembly 5 and the movable mold assembly 6 have convenient structural disassembly and assembly, and the forming mold 7 can use the connecting bolt 604 inside the mounting hole 603 in the movable mold base 601 to be connected to the forming mold 7 by screwing, so that the forming mold 7 is fixed in the middle of the bottom of the movable mold base 601.

[0025] like Figures 1 to 4As shown, the fixed module 2 includes a vibration table 201, a lower support pile 202, a lower mold 203 and a limiting tube 204. The lower support piles 202 are provided on the left and right sides of the vibration table 201, and the lower mold 203 is installed on the top of the vibration table 201, and the limiting tubes 204 are symmetrically provided on the top of the lower mold 203. The lower mold 203 is fixed in the middle of the top of the vibration table 201, and the lower mold 203 is vertically opposite to the movable mold base 601 and is located on the same vertical central axis.

The operation of the vibration table 201 ensures that the tantalum alloy powder injected into the lower mold 203 is as compact as possible, and at the same time, bubbles and impurities therein are discharged, thereby ensuring the quality of the molded parts to be subsequently processed.

[0027] After the injection of tantalum alloy powder is completed, the operation of the vibration table 201 is stopped, and then the lifting column 3 between the equipment base 1 and the pressing assembly 5 is started to appropriately adjust the relative distance between the top frame 501 and the equipment base 1. Then, the hydraulic cylinder 503 in the middle of the top frame 501 is started. Under the vertical push of the hydraulic cylinder 503, the connecting seat 602 connected to the bottom end by the connecting frame 504 will guide the entire movable mold assembly 6 to move downward in the vertical direction. At this time, the sliders 605 on both sides of the movable mold base 601 will move along the surface of the guide column 8 located between the upper support frame 502 and the lower support pile 202 to ensure the stability of the displacement of the movable mold base 601.

[0028] As the movable mold base 601 moves downward, the forming mold 7 installed at the bottom using the connecting bolt 604 will also move synchronously and gradually dock and combine with the inside of the lower mold 203. During this process, the limiting pile 606 at the bottom of the movable mold base 601 will gradually be vertically inserted into the limiting tube 204 on the top side of the lower mold 203 to ensure the stability of the docking between them, until the internal tantalum alloy powder is pressed into a molded part and the processing is completed.
