[0020] like Figures 1-5 As shown, a surface grinding device for mold steel includes a base frame 1. A protective cover 2 is provided on the top of the base frame 1 to isolate dust and debris generated during grinding and protect workers. A grinding mechanism 3 is installed inside the top of the protective cover 2. The grinding mechanism 3 includes a grinding rod 301. A spray pipe 4 is provided on one side of the grinding rod 301 to spray water and cool it. A water tank 5 is fixedly connected to the top of the protective cover 2 to provide water to the spray pipe 4. A water collection tank 6 is fixedly connected to the bottom of the base frame 1. A through groove 101, communicating with the inside of the water collection tank 6, is opened in the middle of the top of the base frame 1. Waste liquid generated during grinding flows through the through groove 101 under its own gravity. 01. The mold steel is collected in the water collection tank 6. The top of the base frame 1 is slidably connected to a slide table 7 for supporting the mold steel. An electric push rod 8 is installed at the bottom of the base frame 1. The left side of the slide table 7 is slidably connected to the through groove 101. The telescopic rod of the electric push rod 8 is pointing to the left and passes through the right side of the water collection tank 6 and finally connects to the left side of the slide table 7. The extension and retraction of the telescopic rod of the electric push rod 8 can drive the slide table 7 to slide laterally along the through groove 101. The right side of the protective cover 2 has an opening 201 for the slide table 7 to pass through. The slide table 7 is provided with a first limiting component, which is used to limit the mold steel laterally. The top of the base frame 1 is provided with a second limiting component, which is used to limit the mold steel longitudinally.

[0021] The grinding mechanism 3 includes an electric slide rail 302, which is horizontally installed at the top inside the protective cover 2. A cylinder 303 is installed at the output end of the electric slide rail 302, and a U-shaped frame 304 is connected to the output end of the cylinder 303. The grinding rod 301 is rotatably connected inside the U-shaped frame 304. A motor 305 is installed on the outer side of the U-shaped frame 304, and the output shaft of the motor 305 is connected to the grinding rod 301 in a transmission connection.

[0022] The first limiting component includes a movable baffle 901 and a fixed baffle 902. The fixed baffle 902 is fixedly connected to the top right side of the slide table 7. A slide groove 701 is opened on the left side of the slide table 7. A guide rod 903 is fixedly connected in the slide groove 701. The lower end of the movable baffle 901 is slidably connected to the guide rod 903. An elastic element 904 is sleeved on the guide rod 903. The two ends of the elastic element 904 are respectively connected to the right side of the slide groove 701 and the right side of the movable baffle 901. The elastic element 904 is used to provide lateral clamping force.

[0023] The second limiting component includes two clamping plates 1001, which are symmetrically distributed on the top of the base frame 1. Two fixing plates 1003 are symmetrically fixed to the top of the base frame 1. The two fixing plates 1003 are adjacent to the opposite side of the two clamping plates 1001. A guide rod 1004 is fixed to the opposite side of the two clamping plates 1001. The guide rod 1004 is slidably connected to the fixing plate 1003 on the same side. An elastic element 1005 is sleeved on the guide rod 1004. The two ends of the elastic element 1005 are connected to the fixing plate 1003 and the clamping plate 1001, respectively. The elastic element 1005 is used to provide longitudinal clamping force. The right end of the two clamping plates 1001 has a bent portion 1002. The bent portions 1002 of the two clamping plates 1001 are bent in the direction away from each other. This design facilitates pushing the two clamping plates 1001 away from each other when the mold steel enters the protective cover 2.

[0024] Pump 11 is installed on the top of the outer cover 2. The inlet of pump 11 is connected to the bottom of the water storage tank 5 through a water pipe. The outlet of pump 11 is connected to the inside of the nozzle 4 through a telescopic hose. The design of the telescopic hose can accommodate the moving grinding rod 301 in the grinding mechanism 3, ensuring stable water supply support for the nozzle 4.

[0025] A filter screen 12 is slidably connected inside the water collection tank 6 for easy replacement. A second pump 13 is installed on the top of the protective cover 2. The inlet of the second pump 13 is connected to the bottom of the water collection tank 6 through a water pipe, and the outlet of the second pump 13 is connected to the top of the water storage tank 5 through a water pipe. The second pump 13 pumps the waste liquid after the impurities are filtered out by the filter screen 12 into the water storage tank 5 to realize the recycling of water resources.

[0026] An elastic isolation strip 14 is connected inside the through-hole 201. The elastic isolation strip 14 can enhance the sealing of the protective cover 2 while allowing the slide table 7 and the mold steel to freely enter and exit the protective cover 2 through the through-hole 201, preventing the leakage of splashed dust.

[0027] Transparent windows 15 are provided on both the front and back sides of the protective cover 2 to facilitate staff to observe the polishing process and ensure polishing quality and safety.

[0028] Working principle: Initially, the slide table 7 is located on the right side outside the protective cover 2. During use, the mold steel to be ground is placed on the slide table 7 between the moving baffle 901 and the fixed baffle 902. The elastic element 904 provides a lateral clamping force for the mold steel to the moving baffle 901 and the fixed baffle 902. Then, the slide table 7 is driven to move to the left by the electric push rod 8, passing through the through hole 201 and entering the interior of the protective cover 2. During this process, the front and rear sides of the mold steel will respectively meet the bending parts 10 of the two clamping plates 1001. The two clamping plates 1001 come into contact with each other, thus applying a force that moves them away from each other until both the front and rear sides of the mold steel are clamped by the two clamping plates 1001. The elastic element 904 provides a longitudinal clamping force for the mold steel by the two clamping plates 1001, so that the mold steel can be stably clamped below the grinding mechanism 3. Then, the cylinder 303 drives the U-shaped frame 304 and the grinding rod 301 on it to move above the mold steel until the grinding rod 301 touches the upper surface of the mold steel. When in contact, the grinding rod 301 is driven to rotate by the motor 305, and the cylinder 303 and the grinding rod 301 are driven by the output end of the electric slide rail 302 to perform transverse and comprehensive grinding on the surface of the mold steel. During the grinding process, the water in the water storage tank 5 is pumped to the spray pipe 4 by the pump 11 to spray water to cool the grinding rod 301. The waste liquid generated during the grinding process flows into the water collection tank 6 through the channel 101. After being filtered by the filter screen 12, it is pumped by the pump 2 13 and sent back to the water storage tank 5 to realize the recycling of water resources. The protective cover 2 and the elastic isolation belt 14 effectively prevent the sparks and splashes generated during the grinding process from harming the operators and the surrounding environment. At the same time, the transparent window 15 allows the operators to observe the grinding process, ensuring grinding quality and safety. After the grinding is completed, the slide table 7 is driven to move to the right through the through hole 201 and move out to the left side of the protective cover 2 by the electric push rod 8, so that the workers can directly take out the ground mold steel.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
