Description

Technical Field

[0001] The utility model relates to the technical field of compression molding machines, in particular to a combined device for processing an eccentric wheel in an air-conditioning compressor. Background Art

[0002] The air conditioning compressor plays the role of compressing and driving the refrigerant in the air conditioning refrigerant circuit. The air conditioning compressor is generally installed in the outdoor unit. The air conditioning compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the heat sink, and the refrigerant also changes from gas to liquid, and the pressure increases. The working circuit of the air conditioning compressor is divided into an evaporation area (low-pressure area) and a condensation area (high-pressure area). The indoor and outdoor units of the air conditioner belong to the low-pressure or high-pressure area respectively (depending on the working status). The refrigerant then flows from the high-pressure area to the low-pressure area, and is sprayed into the evaporator through the capillary tube. The pressure drops suddenly, and the liquid refrigerant immediately becomes gaseous, absorbing a large amount of heat in the air through the heat sink. When the air conditioning compressor is working, an eccentric wheel is used inside, and the eccentric wheel needs to be processed by die casting.

[0003] After the traditional eccentric wheel die-casting equipment is completed, the eccentric wheel is easy to stick to the mold during die-casting and is difficult to remove, which reduces the processing efficiency of the eccentric wheel. Utility Model Content

[0006] Preferably, four supporting legs are installed in a rectangular array at the four corners of the bottom of the processing table, and a reinforcing rod is installed between the lower ends of the four supporting legs.

[0007] Preferably, the lifting mechanism is composed of a support plate, a polished rod and a lifting electric rod. The support plate is limitedly installed in the lower mold. Four polished rods are installed in a rectangular array at the four corners of the bottom of the support plate. The four polished rods penetrate the processing table and are slidably installed therewith. The lifting electric rod is installed at the bottom of the processing table in the middle of the four polished rods. The extended end of the lifting electric rod is fixed to the bottom of the support plate. By setting the lifting mechanism, the die-cast eccentric wheel can be ejected from the lower mold.

[0008] Preferably, the push mechanism is composed of a support seat, a push plate and an electric push rod, two support seats are provided, the two support seats are symmetrically mounted on the processing table, the electric push rods are mounted on the upper ends of the backs of the two support seats, and the push plates are mounted on the protruding ends of the two electric push rods. By setting the push mechanism, the ejected eccentric wheel can be pushed out of the lower mold.

[0009] Preferably, the control box is installed at the bottom of the processing table close to the outer side of the right support leg, and the control box is respectively connected to the upper electric rod, the hydraulic rod and the electric push rod. By setting the control box, it is convenient to control the eccentric wheel die casting work as a whole.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model is provided with an upper ejection mechanism and a pushing mechanism. After the eccentric wheel is die-cast, the upper ejection electric rod is first started through the control box and then the two electric push rods are started. The upper ejection electric rod drives the supporting plate to rise and push the eccentric wheel out of the lower mold. The two electric push rods drive the pushing plate to push the eccentric wheel out of the lower mold. The pushed out eccentric wheel will slide out of the processing table along the drainage groove, so that the die-cast eccentric wheel can be automatically lifted up and pushed out of the mold, thereby improving the processing efficiency of the eccentric wheel.
