[0037] Working principle: When the die-casting equipment is used to die-cast steam turbine blades, in the die-casting mechanism 4, the fixed die seat 401 is fixed, the fixed seat 404 is fixed, the movable die seat 403 slides along the first guide rod 402, and the first hydraulic cylinder 406 on the fixed seat 404 extends to act on the movable seat 408. At this time, the sliding sleeve 407 slides along the second guide rod 405, and the movable seat 408 moves forward. Through the cooperation of the movable part, the first connecting rod 409 and the second connecting rod 410, the movable die seat 403 can be moved, thereby driving the movable die 412 to dock with the fixed die 411 on the fixed die seat 401;

[0038] At this time, in the injection mechanism 6, raw materials are injected into the injection opening 605 opened in the injection inclined cylinder 603. Due to the inclined setting of the injection inclined cylinder 603, it can be ensured that the raw materials are first gathered at its bottom. At this time, the fourth electric cylinder 602 drives the punch 604 to move in the injection inclined cylinder 603 to push the raw materials. At this time, the raw materials in the injection inclined cylinder 603 are pushed, and the air therein is discharged through the exhaust pipe 606. The raw materials are injected from the bottom of the fixed mold 411 and the movable mold 412. At this time, in the exhaust mechanism 5, the second stepper motor 502 on the support frame 501 drives the rotating plate 503 to rotate, and with the cooperation of the straight limiting rod 504 and the special-shaped limiting rod 505, the exhaust pipe 508 is rotated to the top of the exhaust arc part 413, and the second electric cylinder 506 drives the Z-shaped part 507 to move downward, so that the exhaust pipe 508 is sleeved on the exhaust arc part 413. As the raw material is injected between the fixed mold 411 and the movable mold 412, the air inside enters the exhaust cylinder 508 through the exhaust arc 413, and the air is discharged through the exhaust hole. When the raw material is full, the raw material enters the exhaust cylinder 508 through the exhaust arc 413. As the raw material rises, the raw material reaches the height of the accommodating inclined cylinder 510 and enters it. At this time, the proximity switch on the exhaust cylinder 508 senses the raw material, and then the injection mechanism 6 stops injecting the material. At this time, the third electric cylinder 512 on the sealing box 511 drives the push rod 513, so that the sealing plate seals the bottom of the exhaust cylinder 508. The second stepper motor 502 drives the rotating plate 503, and then the exhaust cylinder 508 is rotated to the top of the material box 415. The second electric cylinder 506 drives the sealing plate to open, and then the overflowed raw material is discharged into the material box 415 to avoid waste of resources.

[0039] After the turbine blade is formed, the movable mold seat 403 moves away from the fixed mold seat 401, and the two second hydraulic cylinders drive the ejector to eject the blade. At the same time, in the export mechanism 2, the first electric cylinder 204 rises, so that the receiving frame 203 receives the blade, and the first stepper motor 206 drives the first gear 207 to drive the second gear 208, so that the two-way screw 209 drives the screw sleeve 210 to approach, so that the clamping rod 211 can clamp the blade, and then the first electric cylinder 204 is shortened to drive the blade to move downward. Since the size of the blade is larger than the receiving channel formed by the export frame 201 and the export roller 202, after the clamping rod 211 releases the blade, the blade can fall on the export roller 202 and be exported.
