[0028] Specifically, the I-shaped frame 13 is installed on the upper side of the hollow barrel 2 through the insertion of the mounting groove 1501 and the mounting block 1509, and then the ink is put into the middle of the top of the I-shaped frame 13, and the output end of the electric telescopic rod 12 is extended to drive the slider 5 to slide up and down in the slide groove 4, so that the column 9 drives the model 11 to move downward in the ink 14 for replicating, and the output end of the electric telescopic rod 12 moves in the opposite direction to take the model 11 out of the ink 14, and at this time, the high-temperature heated molten steel is poured into the replica ink 14 and allowed to stand and cool to form, and after forming, the I-shaped frame 13 is turned over by the T-shaped rod 1508, and the output end of the electric telescopic rod 12 is extended to drive the slider 5 to slide up and down in the slide groove 4, so that the column 9 drives the model 11 to move downward in the ink 14 for replicating, and the output end of the electric telescopic rod 12 moves in the opposite direction to take the model 11 out of the ink 14, and then the high-temperature heated molten steel is poured into the replica ink 14 and allowed to stand and cool to form, and after forming, the I-shaped frame 13 is turned over by the T-shaped rod 1508, and the output end of the electric telescopic rod 12 is extended to drive the slider 5 to slide up and down in the slide groove 4, and then the output end of the electric telescopic rod 12 is extended to drive the slider 5 to slide up and down in the slide groove 4, and then the output end of the electric telescopic rod 12 is extended to drive the model 11 to move downward in the ink 14 for replicating, and the output end of the electric telescopic rod 12 is extended to move in the opposite direction to take the model 11 out of the ink 14, and then the high-temperature heated mol The output end of the electric telescopic rod 12 is telescopically driven by the upright column 9 to drive the model 11 to hit the I-shaped frame 13, so that the bolts in the ink pad 14 fall into the hollow barrel 2. At the same time, when the stepper motor 1502 drives the turntable 1503 to rotate, according to the principle of centrifugal force, the product bolts will carry the ink pad 14 and hit the rubber sleeve 1504 on the inner wall of the hollow barrel 2, so that the ink pad 14 in the thread gap can be better removed by impact. Finally, the sealing door 1505 is opened to take out the product, and the mounting groove 1501 and the mounting block 1509 are plugged together to firmly install the I-shaped frame 13 on the upper side of the hollow barrel 2. Not only the stability of the device is ensured, but also the convenience of operation is greatly improved. The ink pad 14 is placed in the middle of the top of the I-shaped frame 13. The role of the ink pad 14 is to provide an accurate replica surface for the model 11, ensuring that the copied product has the same shape and size as the original model 11. The output end of the electric telescopic rod 12 is telescopic to drive the slider 5 to slide up and down in the slide 4.

When the model 11 is replicated in the ink pad 14, the output end of the electric telescopic rod 12 will move in the opposite direction to remove the model 11 from the ink pad 14. At this time, the molten steel heated at high temperature is poured into the replicated ink pad 14.

It not only improves the manufacturing efficiency and quality of the product, but also reduces the production cost and manpower investment. Through precise control and automated operation, large-scale, high-precision product replication and molding can be achieved.

[0029] A plurality of reinforcing ribs 10 are fixedly connected to the lower and middle parts of the column 9 at equal intervals, and the top ends of the plurality of reinforcing ribs 10 are fixedly connected to the bottom of the lifting plate 6 at equal intervals; support blocks 16 are fixedly connected to the left and right sides of the bottom of the bottom plate 1, and universal wheels 17 are fixedly connected to the front and rear sides of the bottom of the support block 16;

[0030] Specifically, by fixing and installing the reinforcing ribs 10, the pressure of the column 9 is effectively dispersed evenly, and the rigidity and strength of the column 9 are enhanced. At the same time, the installation of the support block 16 and the universal wheel 17 is coordinated to facilitate the transportation and movement of the entire equipment. The reinforcing ribs 10 are carefully designed and accurately installed at the key parts of the column 9. These reinforcing ribs 10 are like ligaments in bones, which disperse the pressure of the column 9 to a larger area and avoid the phenomenon of local overload. In this way, the rigidity and strength of the column 9 are significantly improved, so that it can better cope with the effects of various external forces. At the same time, it is equipped with support blocks 16 and universal wheels 17. The function of the support block 16 is to provide additional support for the column 9 and further enhance its stability. The introduction of the universal wheel 17 makes the entire equipment more convenient during transportation and movement. The wheels can roll flexibly on various ground surfaces, so that the equipment can easily cope with different working environments and transportation requirements. It not only improves the stability and reliability of the equipment, but also reduces the risk of damage to the equipment during transportation. At the same time, it also improves the working efficiency of the equipment and reduces the downtime caused by equipment failure. In summary, through the fixed installation of the reinforcing ribs 10 and the cooperation of the support block 16 and the universal wheel 17, the rigidity and strength of the column 9 are improved, and the entire device is made more convenient during transportation and movement.

[0031] A controller 18 is fixedly connected to the middle and upper part of the rear side of the right angle frame 3, and the controller 18 is electrically connected to the servo motor 8 and the stepper motor 1502 respectively; the hollow barrel 2 is made of stainless steel;

[0032] Specifically, the controller 18 is used to control the servo motor 8 and the stepper motor 1502 respectively. At the same time, the hollow barrel 2 is made of stainless steel, so that the installation slot 1501 and the installation block 1509 provide stronger support when plugged in and installed. The servo motor 8 is widely used in various occasions requiring high-precision positioning and motion control with its excellent response speed and accuracy. The controller 18 can ensure the accurate movement and positioning of each component on the production line through the precise control of the servo motor 8, thereby improving production efficiency and product quality. The stepper motor 1502 plays an important role in the automated production line with its stable rotation speed and simple control method. The controller 18 can achieve continuous and stable rotational motion by controlling the stepper motor 1502, thereby driving various mechanical components on the production line to complete the predetermined work. As a supporting component, the hollow barrel 2 is made of high-quality stainless steel. This material not only has excellent strength and corrosion resistance, but also can provide stronger support for the installation slot 1501 and the installation block 1509. When the mounting groove 1501 and the mounting block 1509 are plugged and installed, the stainless steel hollow barrel 2 can effectively withstand forces from all directions to ensure the stability and reliability of the equipment. In addition, the excellent performance of the stainless steel hollow barrel 2 also helps to improve the durability of the equipment. During long-term use, the stainless steel material can effectively resist corrosion and wear, thereby extending the service life of the equipment. At the same time, its sturdy structure can also withstand external shocks and vibrations to ensure the stable operation of the equipment. In summary, through the precise control of the servo motor 8 and the stepper motor 1502 by the controller 18, and the strong support provided by the hollow barrel 2 made of stainless steel, a stable, reliable and efficient automated production line can be constructed.
