[0002] As market demand for forged pistons increases, production capacity needs to be improved. The production and service life of forged piston dies restrict piston production. Forged pistons offer advantages such as high density, high strength, lightweight, high load bearing capacity, and fatigue resistance, making them widely used in high-end locomotives. Some forged piston dies have complex structures and high forging pressures, ranging from 300-400 tons to 600-800 tons. Such high pressures result in a short die life. Frequent die production and replacement not only increases production costs but also delays production and delivery. Therefore, polishing of forged piston dies is necessary to extend their service life.

[0003] When polishing forged piston molds, the traditional polishing method is to polish the mold through manual polishing. However, manual polishing has low efficiency and slow production speed. At the same time, the polishing is prone to unevenness, which reduces the service life of the mold. Summary of the Invention

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely illustrative and not limiting. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following figures. Therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures. Example 1

[0054] This embodiment provides a surface polishing device for a forged piston die, comprising a body 1 having a working tank 2, and characterized in that it further comprises:

[0055] The lower block 3 is located in the working tank 2 and is fixedly connected to the body 1;

[0056] The upper block 4 is movable up and down on the lower block 3;

[0057] An inner cavity 5 is formed by the lower surface of the upper block 4 and the upper surface of the lower block 3;

[0058] a mold body 6 located in the inner cavity 5;

[0059] A pressing assembly, which is provided on the machine body 1 and is used to press the upper block 4 toward the lower block 3;

[0060] Connecting assembly, the upper block 4 is movably arranged on the lower block 3 through the connecting assembly;

[0061] The extrusion assembly is arranged on the machine body 1, and the mold body 6 is polished by the flowing medium. The extrusion assembly is used to squeeze the flowing medium into the inner cavity 5 to polish the mold body 6.

[0062] When the upper block 4 is pressed toward the lower block 3 , the upper block 4 and the lower block 3 clamp the mold body 6 .

[0063] In this technical solution, the flow medium is SiC paste. When the mold body 6 needs to be polished, the mold body 6 is placed between the upper block 4 and the lower block 3, and then the clamping assembly is started. The clamping assembly presses the upper block 4 so that the upper block 4 is pressed toward the lower block 3, and then the mold body 6 is pressed between the inner cavity 5 of the upper block 4 and the lower block 3. Then, the SiC paste is squeezed into the inner cavity 5 through the extrusion assembly, so that the SiC paste enters the inner cavity 5 to grind the mold body 6 until the mold body 6 reaches a certain degree of smoothness. The polishing time is 600 seconds. After polishing, the surface roughness of the mold body 6 is about Ra0.4, and it has a high degree of smoothness. The high degree of smoothness not only makes the piston material have good fluidity during extrusion in the production of forged piston blanks, but also increases the service life of the mold.

[0064] Through this structural design, the mold body 6 is polished by the flowing medium, which not only makes the polishing uniform, but also shortens the production time of the mold body 6 and increases the service life of the mold body 6. The original production capacity of less than 2,000 molds is increased to 4,000 molds, reducing mold costs while increasing the output of piston blanks. Example 2

[0065] This embodiment provides a surface polishing device for a forged piston mold, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0066] Furthermore, the pressing assembly includes:

[0067] Telescopic rod 7, two telescopic rods 7 are fixedly provided in the body 1, and the two telescopic rods 7 are respectively located on the left and right sides of the lower block 3;

[0068] A pressing plate 8, the lower end of which is fixedly connected to the upper ends of the two telescopic rods 7;

[0069] The pressing plate 8 is located above the upper block 4 .

[0070] With this structural design, by providing the pressing plate 8 and the telescopic rod 7, when it is necessary to press the upper block 4, the telescopic rod 7 is activated, and the telescopic rod 7 drives the pressing plate 8 downward, so that the pressing plate 8 contacts the upper surface of the upper block 4 by moving downward, thereby pressing the upper block 4 downward, thereby clamping the mold body 6 and achieving fixation of the mold body 6. This prevents the mold body 6 from falling out during the polishing process. Two telescopic rods 7 are provided on the left and right, making the pressing force more uniform. Example 3

[0071] This embodiment provides a surface polishing device for a forged piston mold, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0072] Furthermore, the extrusion assembly includes:

[0073] A guide hole 9 is provided on the upper block 4 and is in communication with the inner cavity 5;

[0074] A liquid outlet 10 is provided on the lower block 3 and is in communication with the inner cavity 5;

[0075] A placement hole 11 is provided on the pressing plate 8 for placing a flow medium, and the placement hole 11 is connected to the guide hole 9;

[0076] The telescopic cylinder 12 is fixedly disposed in the machine body 1, and the piston rod end of the telescopic cylinder 12 extends into the working groove 2 and is located above the pressing plate 8;

[0077] When the piston rod end of the telescopic cylinder 12 is pressed into the placement hole 11 , the flow medium in the placement hole 11 flows into the guide hole 9 .

[0078] In this technical solution, when the mold body 6 needs to be polished, the mold body 6 is placed in the cavity 20 between the upper block 4 and the lower block 3, and then the telescopic rod 7 is started to drive the clamping plate 8 to move downward. The clamping plate 8 drives the upper block 4 to clamp the mold body 6, and then the SiC paste is placed in the placement hole 11. The telescopic cylinder 12 is started again, and the telescopic cylinder 12 drives the piston rod end to be pressed toward the placement hole 11, so that the piston rod end of the telescopic cylinder 12 and the SiC paste in the placement hole 11 are squeezed, and the SiC paste in the placement hole 11 is pressed into the guide hole 9. After the SiC paste is pressed into the guide hole 9, it will pass through the guide hole 9 into the inner cavity 5 between the upper block 4 and the lower block 3, so that the SiC paste flows through the mold body 6 to grind the mold body 6, and then the SiC paste flows toward the liquid outlet 10 and flows out of the inner cavity 5 from the liquid outlet 10.

[0079] In the present invention, a cavity 20 is provided in the body 1, which is connected to the liquid outlet 10 and is used to collect the SiC paste flowing out of the liquid outlet 10. The body 1 also has an outlet 21 for discharging the SiC paste in the cavity 20. The SiC paste that has flowed out can be put back into the placement hole 11 for reuse, and the reciprocating cycle allows the SiC paste to grind each part of the mold body 6 until the mold reaches a certain degree of smoothness.

[0080] Through this structural design, by setting up an extrusion assembly, it is convenient to press the SiC paste from the placement hole 11 into the inner cavity 5 through the cooperation of the telescopic cylinder 12 and the placement hole 11 to polish the mold body 6. At the same time, the used SiC paste can be collected for reuse. Example 4

[0081] This embodiment provides a surface polishing device for a forged piston mold, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0082] Furthermore, it also includes:

[0083] The jacket 13 is in the shape of a sleeve. The mold body 6 is located in the jacket 13. The inner cavity 5 formed by the upper block 4 and the lower block 3 matches the jacket 13. The jacket 13 is located in the inner cavity 5.

[0084] A communication hole 14 is formed on the jacket 13 , and is disposed toward the guide hole 9 and the liquid outlet 10 . The communication hole 14 is connected to the inner cavity 5 .

[0085] The flow medium enters the inner cavity 5 through the guide hole 9 , and the flow medium in the inner cavity 5 enters the jacket 13 through the connecting hole 14 to polish the mold body 6 . When the upper block 4 presses the jacket 13 , the jacket 13 clamps the mold body 6 .

[0086] The jacket 13 has a slit extending from one end of the jacket opening to a middle position, so that the jacket 13 can be elastically deformed due to the clamping force.

[0087] The communicating holes 14 are distributed on the end surface of the jacket 13 , and there are a plurality of communicating holes 14 . The positions and diameters of the communicating holes 14 are set according to the positions and areas of the concave and convex portions of the mold.

[0088] In the present technical solution, based on Example 3, when the mold body 6 needs to be polished, the mold body 6 is loaded into the jacket 13, and then the jacket 13 is placed in the cavity 20 between the upper block 4 and the lower block 3, and then the telescopic rod 7 is started to drive the pressing plate 8 to move downward, and the pressing plate 8 drives the upper block 4 to press downward, so that the upper block 4 and the lower block 3 squeeze the jacket 13, so that the gap of the jacket 13 is compressed, and the mold body 6 is firmly buckled, so that the jacket 13 and the mold body 6 will not fall out during the polishing process, and it is convenient to load and remove the jacket 13 and the mold;

[0089] Then, the SiC paste is placed in the placement hole 11, and the telescopic cylinder 12 is started. The telescopic cylinder 12 drives the piston rod end to be pressed toward the placement hole 11, so that the piston rod end of the telescopic cylinder 12 and the SiC paste in the placement hole 11 are squeezed. The pressure causes the SiC paste to enter the guide hole 9 from the placement hole 11. After the SiC paste is pressed into the guide hole 9, it will pass through the guide hole 9 into the inner cavity 5 of the upper block 4. Then, the SiC paste flows from the inner cavity 5 of the upper block 4 toward the connecting hole 14 on the upper half of the end surface of the jacket 13, so that the SiC paste flows into the jacket 13 from the connecting hole 14 on the upper half of the end surface of the jacket 13;

[0090] The SiC paste enters the jacket 13, flows through each complex part of the mold body 6, and then flows out from the connecting hole 14 in the lower half of the end face of the jacket 13, and enters the cavity 20 of the machine body 1 through the liquid outlet 10. The SiC paste is then collected and the cycle repeats, so that the SiC paste grinds each part of the mold until the mold reaches a certain degree of smoothness.

[0091] Through this structural design, by setting up the jacket 13, the jacket 13 can firmly buckle the mold body 6, so that the jacket 13 and the mold body 6 will not fall out during the polishing process, and it is convenient to load and remove the jacket 13 and the mold. At the same time, if a different mold body 6 is replaced, the different mold bodies 6 can be adapted by replacing different internal jackets 13, making the adaptation range wider. Example 5

[0095] The two partition plates 15 are used to prevent the diversion hole 9 from being directly connected to the liquid outlet hole 10 .

[0096] Through this structural design, by setting up the partition plate 15, the direct communication between the guide hole 9 and the liquid outlet 10 is prevented, which can prevent the SiC paste from directly flowing out of the liquid outlet 10 after entering the guide hole 9, and ensure that the flow path of the SiC paste is the guide hole 9-the inner cavity 5 of the upper block 4-the connecting hole 14 in the upper half of the end surface of the jacket 13-the inside of the jacket 13-the connecting hole 14 in the lower half of the end surface of the jacket 13-the liquid outlet 10, so that the SiC paste has a clear flow direction.
