the upper die body 406 moves out of the forming cavity 202, the second hydraulic cylinder 501 drives the second lifting seat 502 to move upwards, so that the second die body 504 can push the workpiece to move out of the forming cavity 202, at the moment, the first electric push rod 204 drives the powder injection slide seat 303 to move, so that the powder injection slide seat 303 can move to the top end of the forming cavity 202, and the workpiece at the outlet of the forming cavity 202 is pushed to move to the same straight line of the push plate 203, at the moment, the second lifting seat 502 drives the second die body 504 to retract, so that the next round of powder injection operation of the powder injection slide seat 303 is facilitated, and the push plate 203 can push the workpiece to enter the sliding plate 205 to finish discharging through the operation of the first electric push rod 204.
In summary, when the powder metallurgy side hole forming die convenient to demolding is used, the first die body 503 and the second die body 504 can be driven to move upwards by the second hydraulic cylinder 501 through the second lifting seat 502, so that the first die body 503 and the second die body 504 can move into the forming cavity 202 to block the bottom end of the forming cavity 202, and the second electric push rod 302 can drive the powder injection slide seat 303 to move to the top end of the forming cavity 202, so that the suction pipe 304 and the powder injection pipe 305 can be communicated with the forming cavity 202;
then, after the powder injection sliding seat 303 moves to a designated position, the first suction and blowing integrated machine 306 works to suck, so that suction force can be transmitted to the suction pipe 304 through the first suction pipe 307, the bottom end of the forming cavity 202 is blocked by the first lower die body 503 and the second lower die body 504 at the moment because the powder injection sliding seat 303 is attached to the workbench 201, the inside of the forming cavity 202 can be vacuumized through suction of the suction pipe 304, after the inside of the forming cavity 202 forms vacuum, the first suction and blowing integrated machine 306 converts the suction into blowing, the metal powder stored in the first suction and blowing integrated machine 306 can enter the forming cavity 202 through the first air blowing pipe 308 and the powder injection pipe 305, and the metal powder can be pumped into the forming cavity 202 by virtue of the first suction and the vacuum, when the metal powder enters the forming cavity 202 through the powder injection pipe 305, the blowing of the powder injection pipe 305 can be matched with the air pressure difference to be rapidly gushed, the condition that the forming quality is influenced because the powder is unevenly distributed in the die structure or the powder does not completely enter the forming cavity 202 in the process can be effectively reduced through the design, and the metal powder can be effectively cleaned by adopting a mode that the metal powder forming cavity is completely enters the forming cavity to remove foreign matters in the forming cavity or the forming cavity by the unexpected condition;
then, after the powder injection slide seat 303 completes powder injection, the first electric push rod 204 works to drive the powder injection slide seat 303 to push back, so that the powder injection slide seat 303 can move away from the top end of the forming cavity 202, at this time, the first lifting seat 404 can drive the upper die body 406 to move to the inside of the forming cavity 202 through the working of the first hydraulic cylinder 403, the co-extrusion of the upper die body 406 and the lower die body two 504 is matched, the metal powder is die-cast and formed into a workpiece, the upper die body 406 blows air through the second suction integrated machine 402 in the extrusion working process, the air flow can be led to enter the inside of the expansion air bag 411 through the second air blowing pipe 407, the expanded expansion air bag 411 can push the stop 412 to slide in the inside of the communicating groove 409, the groove of the upper die body 406 is filled, so that the groove at the bottom end of the upper die body 406 is prevented from being influenced by the extrusion working, the first hydraulic cylinder 403 drives the first lifting seat 404, the upper die body 406 is separated from the workpiece, the second suction integrated machine 402 can suck the air in the inside of the expansion air bag 411, the expansion air bag 411 can drive the stop 412 to reset, the communicating groove 409 and the second suction integrated machine can suck the second suction air bag 202 to be more influenced by the outside the inside of the workpiece, the workpiece is prevented from being exposed out of the communicating groove of the workpiece, the second suction integrated machine 202, the two suction cavity is prevented from being influenced by the suction of the inside of the communicating groove is more sucked into the inside of the communicating groove 410, the workpiece is prevented from being formed by the communicating the upper suction cavity is formed by the suction cavity 202, and the upper suction cavity is more influenced by the suction can be sucked into the inside is prevented from being sucked into the inside the cavity is sucked into the inside is formed by the cavity is sucked by the suction cavity is formed by the suction can be sucked by the suction can is, because the hardness of the formed workpiece is lower without heat treatment, the adsorption type demolding is adopted to replace the traditional push type demolding, so that the hard extrusion of the workpiece can be reduced, and the yield of the workpiece is improved;
if the die casting is not formed or the forming effect is poor, then a large amount of metal powder is drawn out of the forming cavity 202 by the upper die body 406 under the suction operation of the upper die body 406, after the upper die body 406 finishes the suction operation, the first suction and blowing integrated machine 306 pauses the operation, the workpiece is released from the suction of the upper die body 406 and is attached to the top surface of the lower die body 504, at the moment, the device control electromagnet 506 is powered off, the lower die body 504 is sprung up by the reset spring 505 due to the release of the electromagnetic suction of the armature 507 and the electromagnet 506, at the moment, if the workpiece is not damaged, the powder cannot be sucked out by the upper die body 406, when the reset spring 505 is sprung up to push the lower die body 504 upwards, the workpiece is not displaced due to the weight of the workpiece, and if the workpiece is damaged, more metal powder can be sucked by the upper die body 406, at the moment, the reset spring 505 is sprung up smoothly, the lower die body 504 can be sprung up, the tension rope 508 can be tightly caused, the tension sensor 509 can be triggered, through the design, the working personnel can only observe whether the tension sensor 509 responds to the electromagnetic suction sensor 509, and whether the workpiece produced at present is required to be completely removed, and the fact that the device is not qualified in the production process is well is removed;
finally, after the workpiece is detected correctly, the first lifting seat 404 drives the upper die body 406 to move out of the forming cavity 202, the first suction groove 405 at the bottom end of the first lifting seat 404 is close to the workbench 201, when the upper die body 406 performs suction operation, the first suction groove 405 can also perform suction, so that the metal powder remained in the powder injection sliding seat 303 in the powder injection process can be removed from the workbench 201, the workpiece discharging is prevented from being influenced, after the upper die body 406 moves out of the forming cavity 202, the second hydraulic cylinder 501 drives the second lifting seat 502 to move upwards, the second die body 504 can push the workpiece to move out of the forming cavity 202, at the moment, the first electric push rod 204 drives the powder injection sliding seat 303 to move, the powder injection sliding seat 303 can move to the top end of the forming cavity 202, and the workpiece at the position of the outlet of the forming cavity 202 is pushed to move to the same straight line of the push plate 203, at the moment, the second lifting seat 502 drives the second die body 303 to move the next round of powder injection operation of the powder injection sliding seat 303, and the push plate 203 can push the workpiece to slide into the inner part of the slide out plate 205 to complete discharging through the first electric push rod 204.
