[0028] Multiple groups of temperature difference plates A32 and multiple groups of temperature difference plates B43 correspond one to one. Semiconductors and metal plates of two different materials are respectively arranged on the temperature difference plates A32, the temperature difference plates B43 and the refrigeration plate 41. One end of the semiconductors of the two different materials is connected to the metal plate. The two semiconductors on the temperature difference plate A32 and the two semiconductors on the temperature difference plate B43 are connected by wires, one of which is connected to the control system. The two semiconductors on the refrigeration plate 41 are connected to the control system through wires. The two semiconductors and the metal plate on the refrigeration plate 41 are the cooling end of the Peltier effect, the two semiconductors and the metal plate on the temperature difference plate A32 are the hot end of the Seebeck effect, and the two semiconductors and the metal plate on the temperature difference plate B43 are the cold end of the Seebeck effect.

[0029] Working principle: Press the start button on the control panel 1, the casting equipment starts, the control system connects the heating wire on the heating plate 31 to the circuit, the heating plate 31 heats the molten metal to the set temperature through the heating wire, after the molten metal is heated to the set temperature, the temperature sensor feeds back the data to the control system, controls the solenoid valve in the pipeline between the pouring port 221 and the heating box 3 to open, and then delivers the inert gas to the heating box 3 through the air source system, the molten metal is driven by the inert gas to the cavity in the upper die base 22 and the lower die base 23, and the molten metal is cast into an impeller through the cooperation of the upper die base 22 and the lower die base 23.

[0030] When the molten metal enters the upper die seat 22 and the lower die seat 23, the control system controls the drive motor 2 to drive the sun gear 24 to continuously rotate forward and reverse by a certain angle. With the cooperation of the planetary carrier 243 and the ring gear 242, the planetary gear 241 rotates while revolving. Since the vertical shaft 244 is eccentrically arranged on the planetary gear 241 and the vertical shaft 244 slides in the sliding groove 211, the vertical shaft 244 on the planetary gear 241 drives the vibration plate 21 to vibrate continuously through the sliding groove 211, and the vibration plate 21 drives the rotating frame 14 to vibrate continuously. The rotating frame 14 drives the upper die seat 22 and the lower die seat 23 to vibrate. The upper die seat 22 and the lower die seat 23 drive the molten metal in the cavity to flow continuously, so that the molten metal is more evenly distributed in the cavity, thereby improving the yield rate of impeller casting.

[0031] When the impeller needs to be cooled after being cast for a set time, the control system quickly cools down the coolant through the refrigeration end on the refrigeration plate 41. When the coolant is cooled to the set temperature, the temperature sensor in the circulation box 4 feeds back the data to the control system. The control system extracts the coolant under the partition into the spiral flow channel 42 of the upper mold base 22 and the lower mold base 23 through the extraction pump 44 and the pipeline. The spiral flow channel 42 increases the cooling area and improves the cooling effect, so that the upper mold base 22, the lower mold base 23 and the cast impeller are quickly cooled. After that, the coolant is transported to the top of the partition through the outlet of the spiral flow channel 42 and the pipeline.

[0032] After the impeller is cast to the set time, the control system connects the two semiconductors on the temperature difference plate A32 and the temperature difference plate B43 to the circuit, and the coolant passes through the spiral flow channel 42 and enters the upper side of the circulation box 4, and the coolant contacts the temperature difference plate B43. The temperature difference plate A32 is located in the heating box 3, so the temperature of the hot end is higher than that of the cold end. The hot end and the cold end generate current through the Seebeck effect and transmit it to the control system. The control system uses the current for cooling the cooling end after transformation and rectification to reduce the overall energy consumption of the impeller casting equipment. When the current generated by the Seebeck effect is small, the control system directly supplies power to the cooling end to ensure normal cooling of the cooling end. The control system also opens the switch valve on the partition to allow the coolant to flow back to the bottom of the partition to achieve recycling of the coolant.

[0033] After the impeller is cooled and formed, the control system controls the lifting cylinder 231 to drive the upper mold base 22 to move upward so that the clamp can enter the position between the upper mold base 22 and the lower mold base 23. The industrial robot drives the clamp to enter the position between the upper mold base 22 and the lower mold base 23, positions and clamps the impeller, and moves the impeller to the detection plate 162.

[0034] When the impeller is placed on the inspection plate 162, the control system identifies the surface of the impeller through the visual camera 12, and compares the data of the control system to determine whether the impeller is a qualified product or a defective product. If the control system determines that the impeller is a defective product, the control system controls the transverse motor 16 to drive the screw rod 161 to rotate, the screw rod 161 drives the inspection plate 162 to move, and the inspection plate 162 drives the impeller to move, so that the defective position on the impeller is located directly below the marking frame 152, and the electric cylinder 151 drives the marking frame 152 to move downward, so that the spray hole on the marking frame 152 is close to the defective position of the impeller.

[0035] When the marking frame 152 is close to the impeller, the electric cylinder 151 feeds back the position data to the control system, and the control system controls the metal wire 154 to connect to the circuit. The metal wire 154 generates heat and conducts it to the heat-conducting medium. The heat-conducting medium expands after absorbing the heat, and the expanded heat-conducting medium squeezes the expansion membrane 153, so that the expansion membrane 153 bends toward the side of the marking liquid. While the expansion membrane 153 bends, it squeezes the marking liquid through the spray hole and sprays it on the bad position of the impeller. The marking liquid marks the bad position for subsequent processing. Afterwards, the control system places the impeller in the waste box 13 through the cooperation of the industrial robot and the clamp to realize the collection of impeller waste.
