[0002] Track wheel castings are a type of component used to support and cushion the weight of mechanical equipment. They are usually used in crawler-type engineering machinery such as excavators and bulldozers. The main function of track wheel castings is to support the weight of the equipment and ensure that the track can move smoothly along the wheels. At the same time, they also play a role in cushioning and bearing loads. Track wheel castings need to be cast with the help of a molding device during the processing process.

[0003] For example, the announcement number is: CN221952266U (named as a wheel body processing and forming device for a supporting wheel), which includes a support foot, a support plate is arranged at the upper end of the support foot, a first vertical plate is arranged at the rear side of the upper end of the support plate, and a horizontal plate is arranged on the front end outer wall of the first vertical plate; a forming mechanism includes a slide groove provided on the upper end of the support plate; a clamping mechanism includes a mounting cylinder arranged on the front end outer wall of the first vertical plate; a rotating mechanism includes a motor arranged on the right side of the upper end of the horizontal plate, a driving wheel is arranged at the output end of the motor, a synchronous belt is sleeved on the circumferential outer wall of the driving wheel, and the A driven wheel is meshed with the inner wall of the left circumference of the synchronous belt, and a rotating disk is installed at the lower end of the driven wheel. The motor drives the driving wheel to rotate, the driving wheel drives the synchronous belt to rotate, the synchronous belt drives the driven wheel to rotate, the driven wheel drives the rotating disk to rotate, the rotating disk drives the cylinder to rotate, the cylinder drives the lifting frame to move up and down, and the grinding frame is driven by the stabilizing frame to lift and move and stably protect it. The grinding frame moves up and down and rotates, so as to grind the surface of the formed wheel body, remove burrs to make its surface smooth, which is convenient for subsequent use, and the grinding is carried out immediately after the wheel body is formed, thereby improving the forming efficiency.

[0004] The above-mentioned molding device assists the support wheel in efficient processing by setting up multiple movable mechanisms, but the casting needs to be cooled. The use of water cooling will cause the water to vaporize after being heated, resulting in a large amount of water being consumed during the cooling process.

[0019] Preferably, one end of the steam guide pipe is connected to a connecting sleeve, and the steam guide pipe is sleeve-sealed and connected to the steam outlet inside the plug-in sealing plate through the connecting sleeve.

[0020] Preferably, the molding process of the roller casting molding device comprises the following steps:

[0021] Step 1: Pour the molten steel in the ladle into the inside of the ladle shroud, so that the molten steel flows into the inside of the two casting molds through the ladle shroud, and then the hydraulic cylinder drives the support frame plate to descend, so that the two casting molds fall into the inside of the immersion frame;

[0022] Step 2: Finally, the plug-in sealing plate is assembled and connected with the closed slot, and the plug-in sealing plate is installed on the top position of the immersion frame to seal the immersion frame, and the connection sleeve is sealed and connected to the steam outlet, and then the water in the temporary water tank is pumped out by the upper water pump and injected into the interior of the immersion frame through the upper water pipe;

[0027] Step 7: Turn the handle to drive the two threaded linkage rods to move outward along the threaded hole seat, so that the two casting molds can move separately along the guide slide, making it easy to take out the support wheel casting that has been cooled and formed after casting.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. The present invention performs a cooling treatment on the casting mold by immersing it in a water immersion frame through cold water. The cold water is preheated and vaporized after contacting the casting mold, and the casting mold is cooled. The water vapor generated by vaporization continuously enters the interior of the condenser through the steam outlet and the steam guide pipe. The condenser condenses the water vapor into water and injects it into the water receiving bucket. Then, the reflux pump draws out the cold water in the temporary water tank through two reflux pipes and injects it back into the immersion frame for reuse. In the whole process, the cooling water required for casting is not lost, which saves the consumption of water resources. The existing molding device overcomes the problem that the casting needs to be cooled for casting by auxiliary support wheels with multiple movable mechanisms, and the water cooling method causes the water to vaporize after being heated, resulting in a large amount of water consumption during the cooling process.

[0030] 2. The support frame is driven down by the hydraulic cylinder, so that the two casting molds fall into the inside of the immersion frame. After cooling, pull the grab handle to remove the plug-in sealing plate from the top of the immersion frame, and then drive the support frame to rise up and out of the water by the hydraulic cylinder, and open the drain valve to drain the water in the immersion frame into the temporary water tank through the drain pipe. Turn the handle to drive the two threaded linkage rods to move outward along the threaded hole seat, so that the two casting molds are separated and moved along the guide slide, which is convenient for taking out the support wheel casting that has been cooled and formed after casting, thereby improving the processing efficiency of the support wheel casting casting.
