[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example

[0020] like Figures 1 to 8 As shown, a wear-resistant alloy casting and molding equipment includes a workbench 1, a working cavity 14 above the workbench 1, a circular sliding fixing plate 15 inside the working cavity 14, a circular placement platform 22 rotatably mounted above the circular sliding fixing plate 15, four placement slots 17 above the circular placement platform 22, the four placement slots 17 being circumferentially distributed and each having a rotatably mounted an annular alloy mold 221, and each placement slot 17 having a rotating slot 171 at its bottom, the rotating slot 171 being movable through the circular mold. The circular placement platform 22 has a controller 18 on its front side, and a robotic arm 16 on one side wall of the worktable 1. A circular pressing plate 161 is mounted on the robotic arm 16, which fits into the annular alloy mold 221. Four sealing rings 33 are also mounted above the circular placement platform 22, arranged circumferentially. Each sealing ring 33 fits into the inner cavity of the annular alloy mold 221, polishing the corresponding alloy material within the mold's inner cavity. The four placement slots 17 of the circular placement platform 22 adapt to the annular alloy mold 221, and the rotating slots 171 facilitate smooth mold rotation, supporting continuous casting and improving efficiency. The controller 18 regulates the servo motor 21 to achieve automated operation, reducing manual intervention. The circular pressing plate 161 of the robotic arm 16 precisely fits into the annular alloy mold 221, ensuring high pressing accuracy. The four sealing rings 33 respectively fit into the inner cavity of the annular alloy mold 221 to polish the alloy material, avoiding material deviation.

[0021] like Figures 1 to 8 As shown in the specific embodiment, each annular alloy mold 221 is provided with a rotating rod 23 at its bottom. Each rotating rod 23 is movably inserted through the rotating slot 171, and a drive gear 231 is provided at the end of each rotating rod 23 away from the annular alloy mold 221. In this configuration, the rotating rod 23 is coaxially fixed to the bottom of the annular alloy mold 221, and the rotating rod 23 forms a movable rotational engagement with the circular placement platform 22 through the rotating slot 171. The drive gear 231 is fixedly connected to the bottom end of the rotating rod 23, and is used to transmit the meshing torque to the annular alloy mold 221, so as to realize the mold's rotation around its own axis.

[0022] like Figures 1 to 8 As shown, furthermore, semi-circular toothed rings 232 are meshed on one side wall of each of the four drive gears 231, and the semi-circular toothed rings 232 are respectively disposed on the inner wall of the working cavity 14. In this configuration, the semi-circular toothed rings 232 are fixedly installed on the inner side wall of the working cavity 14, forming a meshing transmission pair with the drive gears 231; when the circular placement platform 22 drives the drive gears 231 to revolve to the meshing area, the drive gears 231 mesh with the semi-circular toothed rings 232 to generate rotation, and the meshing angle is limited by the arc length of the semi-circular toothed rings 232, so as to realize the precise rotation of the annular alloy mold 221 at the designated station.

[0023] like Figures 1 to 8 As shown, a servo motor 21 is further installed inside the working cavity 14. A rotating rod 211 is installed at the output end of the servo motor 21, with the end of the rotating rod 211 away from the servo motor 21 located at the center of the bottom of the circular placement platform 22. In this configuration, the servo motor 21 is fixedly installed at the bottom of the working cavity 14, and the two ends of the rotating rod 211 are fixedly connected to the output end of the servo motor 21 and the center of the circular placement platform 22, respectively. The servo motor 21 drives the circular placement platform 22 to revolve in a circle through the rotating rod 211, realizing the switching of the work position of the annular alloy mold 221 and ensuring the accuracy of rotation start and stop and the stability of operation.

[0024] like Figures 1 to 8 As shown, furthermore, four support rods 11 are provided above the worktable 1, symmetrically arranged in pairs. A top plate 12 is also provided above the four support rods 11. The top plate 12 is U-shaped, and a connecting piece 13 is provided on the opposite side wall of the inner cavity of the top plate 12. In this configuration, the support rods 11 are vertically fixed to the upper end face of the worktable 1, providing stable support for the top plate 12; the U-shaped top plate 12 is mounted above the circular placement platform 22, and the connecting piece 13 is fixed to the side wall of the inner cavity of the top plate 12 for installing the upper grinding and transmission components, forming a stable upper support structure to ensure the reliable operation of components such as the sealing ring 33. Example

[0025] The difference between the above embodiments and this embodiment is that: Figures 1 to 8As shown, a wear-resistant alloy casting and forming equipment has a rotating rod 24 located above the center of a circular placement platform 22. A mounting bearing 241 is located at the end of the rotating rod 24 away from the circular placement platform 22 and is mounted on the connecting member 13.

[0026] like Figures 1 to 8 As shown, in a specific embodiment, a circular mounting plate 3 is provided at the bottom of the connector 13, and a circular mounting platform 31 is provided at the bottom of the circular mounting plate 3. The bottom of the circular mounting platform 31 is irregularly shaped and consists of an upper semicircular surface 311, two inclined surfaces 312, and a lower semicircular surface 313. Four sliding balls 32 are slidably arranged at the bottom, and the four sliding balls 32 are symmetrical to each other in pairs. In this configuration, the circular mounting plate 3 is fixed to the bottom of the connector 13, and the circular mounting platform 31 is coaxially installed below the circular mounting plate 3. Its bottom is formed by the smooth connection of the upper semicircular surface 311, the inclined surface 312, and the lower semicircular surface 313 to form an irregularly shaped guide surface. The sliding balls 32 roll in cooperation with the bottom of the circular mounting platform 31, converting the circumferential motion into vertical lifting motion, providing displacement drive for the sealing ring 33 to be pressed down and polished.

[0027] like Figures 1 to 8 As shown, furthermore, each of the four sliding balls 32 is provided with a connecting rod 321 at its bottom. The four connecting rods 321 are distributed circumferentially, and a sealing ring 33 is provided at the end of each connecting rod 321 away from the sliding ball 32. In this configuration, the upper end of the connecting rod 321 is fixed to the sliding ball 32, and the lower end is fixedly connected to the sealing ring 33. When the sliding ball 32 rolls along the curved surface of the annular mounting platform 31, it drives the connecting rod 321 and the sealing ring 33 to rise and fall synchronously. The shape of the sealing ring 33 fits the inner cavity of the annular alloy mold 221 and is used to press and polish the upper surface of the alloy material to ensure that the forming surface is flat and without deviation.

[0028] like Figures 1 to 8 As shown, furthermore, four connecting rods 323 are provided around the rotating rod 24, arranged in a circle. Each of the four connecting rods 323 has a circular collar 322 at its end furthest from the rotating rod 24, and these four circular collars 322 are respectively fitted onto the connecting rod 321. In this configuration, both ends of the connecting rod 323 are fixedly connected to the rotating rod 24 and the circular collar 322, respectively, while the circular collar 322 is movably fitted onto the connecting rod 321. When the rotating rod 24 revolves synchronously with the circular placement platform 22, the connecting rod 323 and the circular collar 322 drive the connecting rod 321 to rotate in the same speed and direction as the annular alloy mold 221, ensuring that the grinding action of the sealing ring 33 is synchronized with the mold's rotation, thus improving the uniformity of the grinding. Example

[0029] This invention also discloses a method for casting and molding wear-resistant alloys, the steps of which are as follows: Step 1: The worker puts the wear-resistant alloy material into the inner cavity of the annular alloy mold 221 on the circular placement table 22 to initially compact the alloy material. After completion, the worker operates the controller 18 on the front side of the workbench 1 to complete the parameter setting and equipment start-up preparation before processing. Step 2: Controller 18 starts servo motor 21. Servo motor 21 drives circular placement platform 22 to rotate via rotating rod 211, which in turn drives annular alloy mold 221 to rotate. Rotating rod 23 at the bottom of mold and drive gear 231 rotate synchronously. Drive gear 231 rotates 15 degrees and meshes with semi-circular toothed ring 232, driving annular alloy mold 221 to rotate. Step 3: The circular placement platform 22 drives the rotating rod 24 to rotate. The rotating rod 24 drives the connecting rod 321 to rotate synchronously through the connecting rod 323 and the circular collar 322. The sliding ball 32 at the top of the connecting rod 321 slides along the upper semicircular surface 311, the inclined surface 312, and the lower semicircular surface 313 of the circular mounting platform 31. The connecting rod 321 moves down, and the sealing ring 33 presses against the upper surface of the alloy and completes the grinding with the rotation of the mold. Step 4: The circular placement platform 22 drives the annular alloy mold 221 to rotate 180 degrees and then stops. The controller 18 controls the movement of the robotic arm 16. The robotic arm 16 drives the circular pressing plate 161 to press down, precisely pressing the alloy material in the annular alloy mold 221 to complete the wear-resistant alloy casting. Step 5: After the molding is completed, the equipment is reset, the circular placement table 22 switches stations, and the alloy material is put back into the empty annular alloy mold 221. The feeding, rotation, grinding and pressing processes are repeated to realize the continuous casting and molding process of wear-resistant alloy.

[0030] The implementation principle of the wear-resistant alloy casting and molding equipment of the present invention is as follows: First, the staff places the alloy material into the inner cavity of the annular alloy mold 221 and performs preliminary compaction. After placement, the staff controls the servo motor 21 to run through the controller 18. Therefore, the servo motor 21 can drive the rotating rod 211 to rotate. When the rotating rod 211 rotates, it can drive the circular placement platform 22 to rotate. When the circular placement platform 22 rotates, it can drive the annular alloy mold 221 to rotate, thereby driving the alloy material to rotate as well. At the same time, when the annular alloy mold 221 rotates, it can drive the rotating rod 23 and the drive gear 231 set at the bottom to rotate. When the drive gear 231 rotates, it can mesh with the semi-circular toothed ring 232 when it rotates 15 degrees, thus enabling the drive gear 231 to rotate. When the drive gear 231 rotates, it can drive the rotating rod 23 to rotate. When the rotating rod 23 rotates, it can drive the annular alloy mold 221 to rotate, thus driving the alloy material placed and compacted in the annular alloy mold 221 to rotate. When the circular placement platform 22 rotates, it can drive the rotating rod 24 to rotate. When the rotating rod 24 rotates, it can drive the circular collar 322 to rotate through the connecting rods 323 set around it. Therefore, the circular collar 322 can drive the connecting rod 321 to rotate, so that the connecting rod 321 and the annular alloy mold 221 rotate synchronously. When the connecting rod 321 rotates, it can slide through the sliding ball 32 and the annular mounting platform 31 provided above. Since the bottom of the annular mounting platform 31 is provided with an upper semicircular surface 311, an inclined surface 312 and a lower semicircular surface 313, the connecting rod 321 can move vertically up and down. When the circular placement platform 22 rotates to 15 degrees, the connecting rod 321 moves from the upper semicircular surface 311 through the inclined surface 312 to the lower semicircular surface 313 (therefore, the movement trajectory is downward). When the annular alloy mold 221 rotates, the sealing ring 33 at the bottom of the connecting rod 321 presses against the alloy material placed inside the annular alloy mold 221. Therefore, as the circular placement platform 22 continues to rotate, it can push the material inside the annular alloy mold 221 flat through the sealing ring 33, ensuring that there will be no material deviation before the wear-resistant alloy is cast. When the circular placement platform 22 rotates 180 degrees, it stops rotating and the robotic arm 16 drives the circular pressing plate 161 to press the alloy material placed in the inner cavity of the annular alloy mold 221, thereby completing the wear-resistant alloy casting. The previously processed annular alloy mold 221 can also hold alloy material, which facilitates continuous casting of wear-resistant alloy. Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
