Description

Technical Field

[0001] The utility model relates to the technical field of air compressor rotor molding, in particular to high-efficiency molding equipment for air compressor rotors. Background Art

[0002] An air compressor is a device that converts power into compressed air energy by compressing air. The rotor is one of the most important parts of an air compressor; the air compressor rotor refers to the part that actively rotates or assists in rotating during the air compression process; according to different classification methods, the air compressor rotor can be divided into reciprocating rotors and screw rotors.

[0003] For example, an air compressor rotor casting mold with the authorization announcement number "CN204524185U" can solve the problems of complex structure, cumbersome use and maintenance, low production efficiency, poor product performance, and short service life. It has a simple and reasonable structure, is easy to use and maintain, has high production efficiency, good product performance, and a long service life. However, after the casting material is fed into the air compressor rotor casting mold, the mold position is fixed, which is easy to cause blockage and gas cavities. The operator needs to manually handle it to ensure the quality after pouring, so it takes a long time to cast and form, which reduces work efficiency. At the same time, the air compressor rotor casting mold cannot control the flow rate during feeding, which easily causes air holes due to too fast casting or slag inclusions and cold shuts due to too slow casting, which makes the air compressor rotor unqualified after casting, thereby reducing the work quality. Utility Model Content

At the same time, the air compressor rotor casting mold cannot control the flow rate during feeding, which is easy to cause air holes due to too fast casting or slag inclusion and cold shut due to too slow casting, thereby causing the air compressor rotor after casting to be unqualified, thereby reducing the work quality. A high-efficiency molding device for air compressor rotors is proposed.

[0027] Working principle:

[0028] When using molding equipment to make air compressor rotors:

[0029] Moulding process:

[0030] The operator first starts the power supply of multiple first hydraulic cylinders 2. The telescopic end of the first hydraulic cylinder 2 extends to drive the movable plate 4 to move to the right, thereby driving the left mold 11 to move to the right. When the surface of the left mold 11 is tightly fitted with the surface of the right mold 9, the power supply of multiple first hydraulic cylinders 2 is turned off, thereby completing the mold closing process.

[0031] Feeding process:

[0032] First, start the power supply of motor 502. The rotation of motor 502 drives the rotating rod 503 to rotate, thereby driving the transmission rod 504 to move back and forth. The back and forth movement of transmission rod 504 drives the movable frame 505 to slide back and forth along the slide groove processed on the protruding part of the inner wall of the second shell 501. The movable frame 505 moves back and forth to drive the cross bar 506 to slide back and forth along the through hole processed on the second shell 501. The back and forth movement of cross bar 506 drives the baffle 6 to slide back and forth along the slide groove processed on the feed pipe 8. Then the operator manually adds the casting material for making the air compressor rotor from the feed pipe 8 into the cavity formed between the left mold 11 and the right mold 9, so that the baffle 6 can control the speed at which the casting material for making the air compressor rotor enters, thereby improving the work quality. After the feeding is completed, the surface of the baffle 6 is pressed against the end of the feed pipe 8, and the power supply of motor 502 is turned off.

[0033] Molding process:

[0034] The operator manually turns the bolt 7 counterclockwise to move the bolt 7 away from the right mold, and starts the power supply of the second hydraulic cylinder 302. The telescopic end of the second hydraulic cylinder 302 moves back and forth, driving the protruding part of the rack 303 to slide back and forth along the slide groove processed on the first shell 301. The movement of the rack 303 drives the first gear 304 to rotate back and forth, thereby driving the second gear 305 to rotate back and forth. The back and forth rotation of the second gear 305 drives the rotating shaft 306 to rotate back and forth. The back and forth rotation of the rotating shaft 306 drives the left mold 11 and the right mold 9 to swing back and forth, so as to move the casting material for making the air compressor rotor back and forth, which can prevent blockage and gas cavity, thereby improving the efficiency of air compressor rotor molding. Finally, after cooling and molding, the first hydraulic cylinder 2 is started, so that the left mold 11 is reset when the telescopic end of the first hydraulic cylinder 2 is retracted, completing the mold opening process, and the operator takes out the molded air compressor rotor.
