The cooling water tank 71 is fixedly connected to the bottom of the mounting plate 3. The heat exchange tube of the tubular heat exchanger 72 passes through the bottom of the cooling water tank 71 and extends to the inside of the cooling water tank 71.

The tubular heat exchanger 72 is a common heat exchange device for transferring heat between fluids. It consists of a series of tubes, one of which flows through the internal pipes and the other flows through the tubes on the outside. Heat exchange occurs at the contact interface between the two fluids inside and outside the tubes.

[0028] See also Figure 3-4 The water outlet pipe 76 is connected to the external cooling cavity 10, and the water outlet pipe 76 is fixedly connected to a support plate 4 and a load-bearing plate 2 respectively.

The insides of the water outlet pipe 76, the cooling water tank 71, the water pipe 74 and the pumping pipe 73 are all loaded with coolant.

The water pipe 74 is connected to the external cooling cavity 10, and the water pipe 74 is fixedly connected to another support plate 4 and another load-bearing plate 2 respectively.

[0029] Specific implementation method: By starting the four electric lifting rods 61 inside the lifting pouring demoulding component 6, the lifting plate 62 can be driven to move downward, and the lifting plate 62 drives the demoulding seat 63, the electromagnet 64 and the three-way infusion pipe 65 to move downward at the same time. The two insulation sleeves 66 are made of lead-antimony alloy with poor thermal conductivity, so that the electromagnet 64 can be insulated and protected. The two bottom ends of the three-way infusion pipe 65 are respectively aligned with the two sides of the top of the mold groove 8. The molten steel can be transported to the two bottom ends through the three-way infusion pipe 65, and then transported to the inside of the mold groove 8 for pouring.

[0030] After pouring is completed, the pipeline connected to the top of the three-way liquid delivery pipe 65 is closed, and the water pump 75 inside the circulating cooling assembly 7 is started to extract the coolant inside the external cooling cavity 10 from the water delivery pipe 74 and transport it to the inside of the cooling water tank 71. By starting the tubular heat exchanger 72, the coolant inside the cooling water tank 71 can be heat-exchanged and cooled. The cooled coolant is sequentially transported to the water pump pipe 73 and the water outlet pipe 76, and the one-way valve on the water outlet pipe 76 is opened by water pressure to transport the cooled coolant to the external cooling cavity 10. Internally, since the outer cooling cavity 10 is connected with the inner cooling cavity 9, the coolants in the two cooling cavities can be mixed for heat exchange. The inner cooling cavity 9 is in the shape of a hollow three-dimensional circular ring, and the outer cooling cavity 10 is in the shape of a hollow three-dimensional circular ring. The inner cooling cavity 9, the die groove 8 and the outer cooling cavity 10 are concentric circles and mutually nested inside and outside. The inner cooling cavity 9 can be used for heat exchange cooling from the inner ring of the die groove 8, and the outer cooling cavity 10 can be used for heat exchange cooling from the outer ring of the die groove 8, thereby accelerating the forming speed of the bearing seat blank inside the die groove 8.

[0031] After the bearing seat blank is formed, the electromagnet 64 is started. When energized, it has magnetic attraction, and the bearing seat blank formed inside the die groove 8 can be demolded upward by magnetic attraction without disassembling the casting die 11, which effectively improves the demolding efficiency of the bearing seat casting.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
