step two, pouring powder to be molded from the top of a cavity surrounded by the elastic outer cylinder 1 and the rigid mold core 4, mechanically vibrating the elastic outer cylinder 1 in the pouring process, avoiding gaps among the powder, enabling the elastic outer cylinder 1 to vibrate to the greatest extent at the moment, facilitating the powder to fully fill each position of a molding cavity, after the powder is filled to a certain amount, rotating down along the fixed screw 9 to move the second fixed nut 7, pushing the connecting sliding sleeve 6 to slide down along the fixed screw 9 by the second fixed nut 7, so that the connecting ring 5 moves down along with the connecting sliding sleeve 6, then driving the connecting ring 10 to move down through the sliding penetrating rod 15, simultaneously pushing the sliding ejector rods 14 at all positions to slide into the annular cavity 35 by the lower pressing ring 16 at the bottom end of the sliding penetrating rod 15, firstly abutting against the corresponding conical butting sleeve 25, when the elastic outer cylinder 1 deforms outwards due to the internal powder extrusion to a certain side position, causing position to protrude out, causing position offset between the conical butting sleeve 25 and the sliding ejector rods 14 to abut against the conical butting sleeve 25, then pushing the sliding ejector rods 14 to abut against the inner side tapered butting sleeve 25 to slide down along the tapered butting sleeve 25, then pushing the sliding sleeve 25 to slide down along the tapered butting sleeve 25, and simultaneously pushing the sliding sleeve 25 to slide along the tapered butting sleeve 25 at the middle position by the sliding supporting hole 23 by the sliding rod 25, and simultaneously pushing the sliding rod 25 at the lower end to slide rod 25 to slide along the tapered butting sleeve 25 to slide hole 25 at the middle position, and the middle part, and the sliding rod 25 is positioned along the tapered butting sleeve 25 and the sliding hole 25, the sliding support mechanisms longitudinally distributed in the support assembly are vertically abutted and reset and centered, and the support assembly is circumferentially distributed in the side wall of the elastic outer cylinder body 1, so that the deformed elastic outer cylinder body 1 can be restored in shape, namely, the shape of powder filled in the inside is regular;
step three, compacting the powder filled between the elastic outer cylinder 1 and the rigid mold core 4 through pressure equipment, because the sliding penetrating rod 15 is fixed in position relative to the sliding penetrating rod 10 by means of connection of the fixed clamping bolt 11, the sliding penetrating rod 15 is fixed in position relative to the fixed screw 9 due to the action of the second fixed nut 7, the sliding ejector rod 14 is connected with the sliding ring 10 through the linkage rod 12, the sliding ejector rod 14 cannot move in transverse position relative to the fixed screw 9, the bottom end of the sliding ejector rod 14 is in butt joint with a sliding supporting mechanism in a supporting assembly, and all sliding supporting mechanisms in the same group are in butt joint in sequence, so that the whole supporting assembly cannot move in transverse position, namely the transverse deformation limitation of the elastic outer cylinder 1 is realized, the deformation of the elastic outer cylinder 1 due to the extrusion of the internal powder is avoided, the regular shape of the powder to be molded is ensured, the elastic outer cylinder 1 is uniformly distributed, namely the elastic outer cylinder 1 becomes the rigid cylinder at the moment, and after the powder is filled and compacted, the first plugging assembly is installed between the elastic outer cylinder 1 and the top of the rigid mold core 4, and the two ends of the whole mold are sealed;
step four, carrying out cold isostatic pressing treatment, extracting fixed clamping bolts 11 at two sides of a linkage ring 10 before treatment, so that the linkage ring 10 can longitudinally move relative to a sliding penetrating rod 15, when one side of an elastic outer cylinder body 1 transversely deforms under the action of pressure in the cold isostatic pressing treatment process, sliding supporting mechanisms longitudinally distributed at the side and sequentially butted together integrally move, then sliding ejector rods 14 butted at the top move along with the sliding supporting mechanisms, the sliding ejector rods 14 transversely slide relative to a lower pressing ring 16 by means of connecting lugs 13 in the moving process of the sliding ejector rods 14, and the connecting lugs 13 push the linkage ring 10 to longitudinally slide along the sliding penetrating rod 15 by virtue of the linkage rod 12 in the sliding process, so that the linkage rods 12 at all positions of the linkage ring 10 move along with the sliding penetrating rod, and the sliding ejector rods 14 at all positions drive the butted sliding supporting mechanisms to synchronously move, so that all positions of the elastic outer cylinder body 1 synchronously deform;
step five, sintering the material body in the cavity enclosed by the elastic outer cylinder body 1 and the rigid mold core 4 to obtain a rotary target;
step six, make the mould put on supporting the layer board 2, and make the second shutoff subassembly be in dismouting opening 34 department, then dismantle the second shutoff subassembly, buffer layer board 31 shelters from in the bottom this moment, avoid inside shaping target to take off and drop and directly strike subaerial damage, then establish the perforation cover that the drawing of patterns roof 33 was installed on the connecting bolt 18 of rigid mold core 4 bottom, then install first fixation nut 19 and fix, then slide the linkage ring 10 along slip through rod 15 upwards, linkage ring 10 just pulls all slip ejector pins 14 through the linkage rod 12 and moves to the direction that keeps away from the center of elasticity outer barrel 1, thereby pull out elasticity outer barrel 1, so that its inner wall separates with fashioned target wall, then dock lifting ring 8 at the top of fixing screw 9 through hoisting device, and dismantle down clamping ring 16 on the slip through rod 15, then upwards lift fixing screw 9, fixing screw 9 just drives rigid mold core 4 upwards, rigid mold core 4 just jack up shaping target through drawing of patterns roof 33, realize effective drawing of patterns.
