Ruiti Metal mainly produces zirconium rods, zirconium plates, zirconium foils, zirconium wires, zirconium tubes, zirconium rings, zirconium targets, zirconium crucibles, zirconium flanges, zirconium fasteners, zirconium processed parts, etc. Zirconium, hafnium and their alloys have outstanding nuclear properties and excellent corrosion resistance and mechanical properties. At present, they are almost all used in the atomic energy industry as the structure, cladding and control rod materials of nuclear reactors. Other aspects are less used due to production and price restrictions.

[0003] The Chinese invention patent with patent application number 202320059957.8 provides a molybdenum-copper alloy powder molding device. By setting up two sets of screw lifting mechanisms, when the molybdenum-copper alloy powder in the molding box needs to be molded, the screw can be better moved with the screw nut, so that the screw nut moves the molding assembly up and down to mold the molybdenum-copper alloy powder in the molding box. The two sets of screws and screw nuts make the molding assembly more stable during the molding process, so that the molybdenum-copper alloy powder after molding is more uniform.

[0004] However, during the use of the above-mentioned equipment, it was found that the alloy powder needs to be placed in a molding box and die-cast using a pressing plate. However, when the alloy powder is placed in the molding box, some of the alloy powder in the molding box tends to accumulate too much, resulting in the alloy powder in the box being not flat enough, causing the density of some areas of the die-cast product to be inconsistent and the shape to be irregular, affecting the dimensional accuracy and appearance quality of the subsequent processed products.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

A second motor 72 is installed inside the motor box 71. A baffle 74 is installed at the bottom of the motor box 71. The output end of the second motor 72 is connected to a rotating frame 73. A rotating groove 731 is provided in the rotating frame 73. A finishing plate 75 is rotatably connected inside the rotating groove 731. A die-casting plate 511 is slidably disposed inside the molding box body 51, and a support frame 512 is fixed at the bottom of the molding box body 51. The support frame 512 is connected to the lifting assembly 9 through a connecting plate 513; The lifting assembly 9 includes a motor 3 91, the output end of the motor 3 91 is connected to a threaded rod 2 92, the threaded rod 2 92 is arranged in a lifting frame 93, and a lifting rod 94 is slidably connected inside the lifting frame 93. The lifting rod 94 is spirally connected to the threaded rod 2 92, and the lifting rod 94 is fixed to the bottom of the die-casting plate 511.

[0020] In this solution, when the device is in use, the user mixes the zirconium and hafnium metal powders and pours them into the molding box body 51, uses the control panel 41 to control the moving assembly 6 to move, drives the threaded rod 1 62 to rotate through the motor 1 61, and uses the spiral connection between the threaded rod 1 62 and the moving frame 63 to enable the moving frame 63 to move along the slide rod 64, thereby driving the finishing assembly 7 to move above the molding box body 51; The electric telescopic rod 8 is used to control the arranging assembly 7 to descend so that the arranging plate 75 in the arranging assembly 7 can contact the metal powder, and the motor 2 72 inside the motor box 71 is used to drive the rotating frame 73 to rotate. When the rotating frame 73 rotates, the arranging plate 75 is controlled to push the mixed metal powder to make it evenly distributed, fill the concave parts, and eliminate the unevenness; The finishing plate 75 rotatably connected in the rotating frame 73 has a certain tilt angle. The tilted finishing plate 75 can have a larger contact area with the metal powder, thereby improving the efficiency and quality of smoothing. A rubber gasket is used to connect the finishing plate 75 and the rotating groove 731 at the rotating connection, thereby increasing the rotational friction between the finishing plate 75 and the rotating groove 731, avoiding accidental rotation of the finishing plate 75, resulting in reduced efficiency of smoothing the metal powder. The finishing plate 75 can fit with the inner wall of the molding box body 51 when rotating, and the two finishing plates 75 are in contact with each other, so that the rotation of the finishing plate 75 covers the entire molding box body 51, so that the metal powder can be completely processed and leveled. The baffle 74 is set with a transparent plate, which can facilitate the user to observe the smoothing condition of the metal powder, thereby ensuring the flatness of the metal powder during die-casting and avoiding the unevenness that causes the molding quality to decrease. After the finishing is completed, the motor 61 controls the threaded rod 62 to rotate in the opposite direction, thereby controlling the moving assembly 6 to drive the finishing assembly 7 to move to one end of the die-casting table 5, and the die-casting machine 3 is used to control the die-casting head 31 to descend. During the descent of the die-casting head 31, the lifting plate 22 connected to the die-casting head 31 descends along the slide column 21, thereby ensuring the stability of the descent of the die-casting head 31, so that the die-casting head 31 can enter the molding box 51. The die-casting head 31 is compatible with the molding box 51, and can pressurize the zirconium-hafnium mixed metal powder mixed inside the molding box 51, so that the zirconium-hafnium mixed metal powder is tightly compacted under pressure to initially form a blank, which is convenient for subsequent sintering and other further heat treatments; After the die-casting of the zirconium-hafnium mixed metal powder is completed, the lifting component 9 is used to lift the die-cast mixed metal to facilitate the staff to take it out. In the lifting component 9, sliders are set on both sides of the bottom of the lifting rod 94, and the sliders are slidably set in the slide grooves on both sides of the lifting frame 93, so that when lifting, the motor 3 91 is used to control the rotation of the threaded rod 2 92. During the rotation of the threaded rod 2 92, the spiral connection between the threaded rod 2 92 and the lifting rod 94 is used to facilitate the lifting of the lifting rod 94 along the slide groove on the inner wall of the lifting frame 93, thereby pushing the die-casting plate 511 to rise in the molding box 51, so as to facilitate the push out of the die-cast zirconium-hafnium mixed metal and facilitate the staff to take it out.
