Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1-Figure 3 A finishing equipment for the surface of mold steel comprises a workbench 1, a polishing disc 3 is rotatably embedded in the workbench 1, a polishing layer is arranged on the top surface of the polishing disc 3, a motor 7 connected to the polishing disc 3 is fixedly installed on the bottom surface of the workbench 1, four fixed blocks 2 located on the outside of the polishing disc 3 are fixedly connected to the top surface of the workbench 1, each fixed block 2 is provided with a connecting plate 6 located above the polishing disc 3, each connecting plate 6 is fixedly connected with a U-shaped connecting frame 8 at one end facing the polishing disc 3, the U-shaped connecting frame 8 is located above the polishing disc 3, each U-shaped connecting frame 8 is provided with a clamping assembly for clamping the mold steel, and there are two types of clamping assemblies, one for clamping and fixing a square Mold steel, another type of mold steel used to clamp cylindrical mold steel, and can clamp multiple mold steels at the same time for simultaneous polishing, thereby improving the efficiency of polishing and maintaining the same polishing quality. The top surface of the workbench 1 is fixedly connected to one side of the fixed block 2 with an L-shaped connecting frame 4, and each L-shaped connecting frame 4 is provided with a clamping assembly for pressing down the connecting plate 6 on the horizontal end. A U-shaped connecting frame 8 is fixedly connected through the connecting plate 6 on each fixed block 2. The clamping assembly arranged in each U-shaped connecting frame 8 can clamp a mold steel, and two of the same type can be clamped, thereby realizing simultaneous polishing of two columns or two squares, thereby improving the practicality of clamping and the efficiency of polishing.

[0024] Reference Figure 3-Figure 4The clamping assembly includes a straight plate 10, and a mounting groove is provided in the horizontal end of each U-shaped connecting frame 8. A lead screw 12 is rotatably connected in each mounting groove. One end of each lead screw 12 extends out of the U-shaped connecting frame 8. One end of the straight plate 10 is threadedly sleeved on the lead screw 12. A knob 11 fixedly connected to the lead screw is provided on the side of the U-shaped connecting frame 8 facing away from the straight plate 10. The mold steel is placed on the polishing disk 3, and then the knob 11 is twisted to rotate the lead screw 12, and then the straight plate 10 is driven to move from one side to the other side, so that the straight plate 10 and one side of the U-shaped connecting frame 8 clamp and fix the mold steel.

[0025] Refer to the figure Figure 3-Figure 4 Two opposing straight plates 10 are provided with anti-slip strips, and another opposing straight plate 10 is provided with a V-shaped plate 13. The straight plates 10 on one side of the U-shaped connecting frame 8 respectively installed on the two opposing side connecting plates 6 and the side of the U-shaped connecting frame 8 opposite to the straight plates 10 are provided with anti-slip strips. The mold steel is clamped tighter by the anti-slip strips to reduce the possibility of the mold steel falling off when the polishing disk 3 rotates. The two opposing straight plates 10 on the other side and the side of the U-shaped connecting frame 8 opposite to the straight plates 10 are fixedly connected with the V-shaped plate 13, which is convenient for clamping the cylindrical mold steel.

[0026] Reference Figure 2 The clamping assembly includes a cylinder 5 fixedly mounted on the top surface of the horizontal end of the L-shaped connecting plate 6. The movable end of the cylinder 5 is fixedly connected to a pressing plate 9 located above the connecting plate 6. As the polishing disc 3 rotates, the clamped mold steel is initially polished, and then the polishing paste is applied to the polishing disc 3. Then, the cylinder 5 pushes the pressing plate 9 to press the connecting plate 6 downward and simultaneously lower the connecting plate 6. At this time, the clamped mold steel at the front end of the connecting plate 6 will be in close contact with the top surface of the polishing disc 3, thereby improving the polishing effect on the mold steel.

[0027] Reference Figure 4 A spring 14 is fixedly connected between the bottom surface of the connecting plate 6 and the top surface of the workbench 1. The spring 14 is coaxial with the pressure plate 9. When the connecting plate 6 is pressed down, the connecting plate 6 presses the spring 14. When the mold steel is polished, the pressure plate 9 is lifted. At this time, the connecting plate 6 will move upward under the action of the spring 14, so that the U-shaped connecting frame 8 at one end of the connecting plate 6 is always located above the polishing disk 3, which is convenient for the installation, clamping and initial polishing of the mold steel. At the same time, the spring 14 is coaxial with the pressure plate 9, which improves the stability of the connecting plate 6 when it rises or falls, and keeps the connecting plate 6 in a horizontal position.

[0028] Reference Figure 2 A connecting ring 16 is fixedly sleeved on the outer side of the bottom end of the polishing disc 3, and a ring groove for the connecting ring 16 to rotate is provided in the workbench 1. When the polishing disc 3 is driven to rotate by the motor 7 and the polishing disc 3 rotates in the workbench 1, the stability of the rotation of the polishing disc 3 is improved through the connecting ring 16 on the polishing disc 3 and the ring groove in the workbench 1.

[0029] Reference Figure 4 A movable groove is opened on one side of the fixed block 2 toward the connecting plate 6, and a guide column 15 is fixedly connected in the movable groove. One end of the connecting plate 6 extending into the movable groove is slidably sleeved on the guide column 15. When the connecting plate 6 is descending, one end of the connecting plate 6 slides along the guide column 15 to improve the movement stability of the connecting plate 6.

[0030] Working principle:

[0031] First, the mold steel is placed between the straight plate 10 or the V-shaped plate 13 according to its shape, so that the bottom surface of the mold steel is in contact with the top surface of the polishing disk 3, and then the straight plate 10 or the V-shaped plate 13 is moved closer to the other side of the vertical end of the U-shaped connecting frame 8 by the knob 11, and the mold steel clamping column is first applied with oil stone to the surface of the polishing disk 3, and then the polishing disk 3 is driven to rotate by the motor 7, the mold steel will contact with the top surface of the polishing disk 3 and perform the initial polishing, and then the motor 7 is stopped, and polishing paste is applied to the surface of the polishing disk 3, and the motor 7 is started again to rotate the polishing disk 3. At this time, according to the number of clamping, the cylinder 5 on one side of the mold steel is started, and the connecting plate 6 is pressed downward by the pressure plate 9 under the cylinder 5. When the connecting plate 6 moves downward, the polishing surface of the mold steel is in close contact with the polishing disk 3, thereby improving the polishing effect. At the same time, multiple mold steels are piled up for clamping to improve the polishing efficiency.
