Description

Technical Field

[0001] This utility model belongs to the technical field of upper mold device, specifically an automatic upper mold device for refrigerator compressor outer shell. Background Technology

[0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas; it is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it using a piston driven by a motor, and then discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe, providing power for the refrigeration cycle and thus realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption). Compressors are classified into reciprocating compressors, screw compressors, centrifugal compressors, linear compressors, etc. This entry introduces the working principle, classification, components, specifications, operating requirements, production, common faults, environmental requirements, selection principles, installation conditions, and development trends of compressors. Compressor housings are generally die-cast; if different sizes of compressor housings need to be die-cast during the process, the die-casting mold needs to be changed, requiring the use of an upper mold device.

[0003] In the existing technology, the replacement of die-casting molds is generally carried out by lifting equipment. However, the lifting equipment cannot rotate the mold during the lifting process, resulting in low mold-up efficiency. In order to solve the above problems, an automatic mold-up device for refrigerator compressor shell is proposed. Utility Model Content

A rotating frame is hinged to one side of the upper end of the upper mold mechanism. A support frame is hinged to one side of the lower end of the upper mold mechanism. A lifting ring is fixedly mounted on the outer wall of the lower end of the rotating frame.

[0006] With the above technical solution, when the upper mold operation is required, the mold to be replaced is first placed on the upper surface of the upper mold mechanism. The equipment is moved to the area to be replaced by the moving base. The upper mold mechanism is lifted by the operation of the cylinder scissor fork frame, thereby realizing the upper mold operation. When the mold needs to be flipped and then the upper mold is installed, the lifting ring is connected to the lifting equipment. The rotating frame is lifted on one side by the lifting equipment. During this process, the rotating frame drives the mold on its upper surface to flip, thereby realizing the flipping upper mold operation.

[0008] With the above technical solution, when the mold to be replaced is placed on the upper surface of the upper mold mechanism, the two fixed plates are moved towards each other by the extension of the cylinder, thereby fixing the mold on the upper surface of the rotating frame and preventing the mold from moving during the flipping process.

[0009] In a preferred embodiment, both the upper mold mechanism and the rotating frame are "L" shaped structures.

[0010] In a preferred embodiment, a telescopic plate is slidably connected inside the support frame, and a locking pin is threadedly connected to the outer wall of one side of the support frame.

[0011] With the above technical solution, when the rotating frame is flipped, the support frame is pulled up and the telescopic plate inside is pulled outward. The position of the telescopic plate is fixed by turning to the locking pin, and the bottom of the rotating frame is supported by the telescopic rod after flipping.

[0012] In a preferred embodiment, conveying rollers are rotatably connected to both the upper and lower sides of the rotating frame.

[0013] The above technical solution facilitates the delivery of the mold from the rotating frame by setting up telescopic rollers.

[0014] In a preferred embodiment, casters are fixedly installed at all four corners of the bottom of the movable base.

[0015] The above technical solution facilitates the movement of the equipment by installing casters.

[0016] In a preferred embodiment, casters are fixedly installed at all four corners of the bottom of the movable base.

[0017] In a preferred embodiment, a push handle is fixedly installed on one side of the upper surface of the movable base.

[0018] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are: this utility model proposes an automatic mold-mounting device for the outer shell of a refrigerator compressor.

When it is necessary to perform the upper mold operation, first place the mold to be replaced on the upper surface of the upper mold mechanism, move the equipment to the area to be replaced by moving the base, and lift the upper mold mechanism by working the cylinder scissor fork frame to realize the upper mold operation. When it is necessary to flip the mold before upper mold, connect the lifting ring to the lifting equipment, and lift one side of the rotating frame by the lifting equipment. During this process, the rotating frame drives the mold on its upper surface to flip, thereby realizing the flip upper mold operation.

When the upper mold operation is required, the mold to be replaced is first placed on the upper surface of the upper mold mechanism 3. The mobile base 1 is used to move the equipment to the area to be replaced. The upper mold mechanism 3 is lifted by the operation of the pneumatic scissor lift 2, thereby realizing the upper mold operation. The four corners of the bottom of the mobile base 1 are all fixedly installed with casters 14. The casters 14 are used to facilitate the movement of the equipment.

[0031] A rotating frame 4 is hinged to one side of the upper mold mechanism 3. Both the upper mold mechanism 3 and the rotating frame 4 are "L" shaped structures. Conveying rollers 7 are rotatably connected inside the upper and lower sides of the rotating frame 4. The mold on the rotating frame 4 is easily sent out by setting the telescopic rollers 7. Mounting plates 8 are fixedly installed on the left and right sides of the lower end of the rotating frame 4. A cylinder 9 is fixedly installed on the upper surface of the mounting plate 8. A fixing plate 10 is fixedly installed at the end of the output shaft of the cylinder 9. When the mold to be replaced is placed on the upper surface of the upper mold mechanism 3, the cylinder 9 extends to move the two fixing plates 10 toward each other, thereby fixing the mold on the upper surface of the rotating frame 4 and preventing the mold from moving during the flipping process.

[0032] A support frame 5 is hinged to one side of the lower end of the upper mold mechanism 3. A telescopic plate 11 is slidably connected inside the support frame 5. A locking pin 12 is threadedly connected to the outer wall of one side of the support frame 5. When the rotating frame 4 is flipped, the support frame 5 is pulled up and the telescopic plate 11 inside is pulled outward. The position of the telescopic plate 11 is fixed by rotating it to the locking pin 12. The bottom of the rotating frame 4 is supported by the telescopic rod 11. A lifting ring 6 is fixedly installed on the outer wall of the lower end of the rotating frame 4. When it is necessary to flip the mold and install the upper mold, the lifting ring 6 is connected to the lifting equipment. The lifting equipment pulls up one side of the rotating frame 4. During this process, the rotating frame 4 drives the mold on its upper surface to flip, thereby realizing the operation of flipping the upper mold.

[0033] Working principle:

[0034] When the upper mold operation is required, the mold to be replaced is first placed on the upper surface of the upper mold mechanism 3. The equipment is moved to the area to be replaced by the moving base 1. The upper mold mechanism 3 is lifted by the operation of the cylinder scissor fork 2, thereby realizing the upper mold operation. When the mold needs to be flipped and then the upper mold is installed, the lifting ring 6 is connected to the lifting equipment. The rotating frame 4 is lifted on one side by the lifting equipment. During this process, the rotating frame 4 drives the mold on its upper surface to flip. After the rotating frame 4 is flipped, the support frame 5 is lifted and the telescopic plate 11 inside is pulled outward. The position of the telescopic plate 11 is fixed by the locking pin 12. The bottom of the flipped rotating frame 4 is supported by the telescopic rod 11, thereby realizing the flipping upper mold operation.
