the alloy powder enters the quantitative pipe 909 to be temporarily stored after passing through the feed pipe 916 and the second through hole 917, then, the pressure head 16 is driven to move downwards by the lifting mechanism 5, when the pressure head 16 moves downwards, the moving plate 503 and the second pushing plate 1001 are driven to move downwards synchronously, at the moment, the second pushing plate 1001 and the side wall of the second sliding plate 911 are not propped against each other, the second sliding plate 911 can slide outwards of the second fixed cover 910 under the action of the third spring 915, so that the second through hole 917 is staggered with the feed pipe 916, the feed pipe 916 is blocked by the second sliding plate 911, and when the second pushing plate 1001 and the first inclined plane 1005 prop against each other, the first pushing block 1004 and the first sliding plate are pushed to slide into the first fixed cover 902, so that the first through hole 904 is aligned with the quantitative pipe 901 909, meanwhile, the second spring 908 is compressed, and at the moment, the alloy powder temporarily stored in the quantitative pipe 909 passes through the first through hole 904 and the L-shaped pipe and enters the fixed pipe 15 and is filled in the upper die 12 and the lower die 13, so that the production efficiency of the alloy powder automatically fed into the upper die 12 and the lower die 13 is ensured;
when the pressing is carried out, the pressing head 16 moves downwards, the position of the moving plate 503 is detected through the distance sensor 704, when the pressing head 16 moves into the fixed pipe 15, the exhaust fan 701 is started, and the upper die 12, the lower die 13 and the fixed pipe 15 are subjected to air extraction operation through the exhaust pipe 702, so that air in alloy powder is automatically discharged, and the casting quality is ensured;
when the pressing head 16 moves downwards, the roller 803 is driven to rotate, the roller 803 rotates to drive the rotating rod 802 to synchronously rotate, when the protrusion 804 is propped against the upper side wall of the moving block 602, the moving block 602 and the knocking rod 603 are pushed to move downwards, meanwhile, the fourth spring 606 is compressed, when the protrusion 804 passes over the upper side wall of the moving block 602, the moving block 602 and the knocking rod 603 can move upwards to reset under the action of the fourth spring 606, so that the knocking rod 603 can make reciprocating knocking vibration on the top of the upper die 12 and transmit the vibration to the lower die 13, thereby ensuring that the metal powder in the upper die 12 and the lower die 13 is filled more uniformly and compactly, reducing the movement of the powder, reducing the abrasion on the upper die 12 and the lower die 13, ensuring the use effect and the service life of the moving block and the knocking rod 603, and facilitating the discharge of air in the metal powder;
after the casting pressing is completed, the pressing head 16 moves upwards, and the second pushing plate 1001 passes over the first pushing block 1004 and the second pushing block 1002 and then abuts against the side wall of the second sliding plate 911 again, so that the second through hole 917 is aligned with the feed pipe 916, the first through hole 904 is staggered with the quantitative pipe 909, and the pressed entity is sintered by the sintering mechanism 4;
after sintering is completed, the sealing door 14 is opened, so that the inclined plate 302 is separated from the first pushing plate 301, and at this time, the lower die 13 moves downwards under the action of the first spring 204 and is separated from the upper die 12, so that the produced product is conveniently taken out, and the production efficiency is improved.
