It adopts the hot core box process for core making and can meet the requirements of coated sand process. It is an ideal equipment for mass production of medium-sized, complex-shaped, and high-requirement casting sand cores.

[0003] However, burrs may appear on the edges of the molds produced by the automatic rotating core shooting machine. The burrs on the surface of the mold are removed by the deburring equipment, making the produced molds more precise.

[0004] However, in the process of using traditional deburring equipment, the mold needs to be manually controlled during the grinding process. This means that the operator's hands need to be in close contact with the rotating grinding tool for a long time, which can lead to injury and reduce the safety of the operator when using the deburring equipment. Utility Model Content

[0005] This utility model addresses the problem in existing technologies where manual control of the mold is required during grinding, resulting in prolonged close contact between the worker's hands and the rotating grinding tool, which can lead to injury and reduce safety when using deburring equipment.

[0007] As a preferred embodiment of the above technical solution, the interior of the placement box is provided with a second slide groove on one side of the first slide groove. A circular rod is fixedly connected to the bottom of the interior of the second slide groove. A slider is slidably connected to the surface of the circular rod. A positioning plate is fixedly connected to the top of the slider. An installation block is fixedly connected to the bottom of the surface of the positioning plate. A plum blossom handle is threadedly connected to the interior of the installation block. The plum blossom handle passes through the interior of the installation block and fits against the inner wall of the placement box.

[0008] As a preferred embodiment of the above technical solution, a silicone pad one is adhered to the surface of the gripper, and a silicone pad two is fixedly connected to the surface of the positioning plate.

[0009] As a preferred embodiment of the above technical solution, the top end of the slider is fitted with the inner wall of the second groove, and the bottom end of the slider is fitted with the surface of the circular rod.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] This utility model provides a deburring device for precision hardware castings, such as... Figures 1 to 5 As shown, the device includes a deburring machine 1, a baffle 2 installed on one end face of the deburring machine 1, a protrusion 3 fixedly connected to one end face of the deburring machine 1, the protrusion 3 being located below the baffle 2, a placement box 4 slidably connected to the top of the protrusion 3, a groove 5 being opened at the bottom of the interior of the placement box 4, a telescopic spring 6 being fixedly connected inside the groove 5, the telescopic spring 6 being fixedly connected to the inner wall of the placement box 4, a connecting block 7 being fixedly connected to one end of the telescopic spring 6, the connecting block 7 being slidably connected inside the groove 5, and a gripper 8 being fixedly connected to the top of the connecting block 7. Existing deburring devices also include a grinding head, a PLC control system, sensors, protective devices, etc. In the process of use, the grinding tool to be ground is placed inside the placement box 4, and the grinding head is controlled by the PLC control system to grind the mold inside the placement box 4. The above are all existing structures and will not be described in detail here.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a second slide groove 10 is provided inside the placement box 4 on one side of the first slide groove 5. A circular rod 11 is fixedly connected to the bottom of the second slide groove 10. A slider 12 is slidably connected to the surface of the circular rod 11. A positioning plate 13 is fixedly connected to the top of the slider 12. An installation block 14 is fixedly connected to the bottom of the surface of the positioning plate 13. A plum blossom handle 15 is threadedly connected to the inside of the installation block 14. The plum blossom handle 15 passes through the inside of the installation block 14 and fits against the inner wall of the placement box 4. When the mold is placed inside the placement box 4, the plum blossom handle 15 is rotated to separate it from the placement box 4. The separation of the boxes 4 allows the mounting block 14 to move. The movement of the mounting block 14 causes the positioning plate 13 to move, and the movement of the positioning plate 13 causes the slider 12 to slide on the surface of the circular rod 11. When the two ends of the mold are in contact with the surface of the deburring machine 1 and the end of the positioning plate 13 on which the silicone pad 16 is installed, the movement stops and the plum blossom handle 15 is rotated in the opposite direction so that the mounting block 14 can no longer move. The positioning plate 13 positions the mold to be polished, so that the mold will not shift when it is polished. This makes the polishing process of the deburring machine 1 more stable and improves the quality of the mold after polishing.

[0025] like Figures 3 to 5 As shown, a silicone pad 9 is attached to the surface of the gripper 8, and a silicone pad 16 is fixedly connected to the surface of the positioning plate 13. When the gripper 8 and the positioning plate 13 clamp the mold, the silicone pads 9 and 16 help prevent the gripper 8 and the positioning plate 13 from scratching the surface of the mold. In addition, the silicone pads 9 and 16 prevent contact between the gripper 8 and the positioning plate and the mold 13, thus avoiding the problem of the mold surface being scratched by the gripper 8 and the positioning plate 13.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, the top of the slider 12 is in contact with the inner wall of the second groove 10, and the bottom of the slider 12 is in contact with the surface of the circular rod 11. When the slider 12 slides on the surface of the circular rod 11, the limiting effect of the second groove 10 makes the sliding process of the slider 12 on the surface of the circular rod 11 more stable, thereby avoiding the problem of the slider 12 deviating when sliding, thus ensuring that the movement of the slider 12 on the surface of the circular rod 11 is smoother and more stable.

[0027] like Figure 4As shown, two locking blocks are fixedly connected to the top of the gripper 8. Springs are installed inside the two locking blocks. When the mold is clamped by the gripper 8, the two locking blocks are pulled to make the mold installation more stable, thereby avoiding the problem of mold displacement during the grinding process and improving the stability of the mold grinding process.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, two mounting blocks 14 are set, and the two mounting blocks 14 are located at the edge of the surface of the positioning plate 13. Both mounting blocks 14 are equipped with a swivel handle 15. When the swivel handle 15 is rotated, it moves slowly downwards. When the bottom end of the swivel handle 15 is in contact with the inner wall of the placement box 4, the swivel handle 15 is rotated again. At this time, the swivel handle 15 will drive the slider 12 to move upwards. When the slider 12 moves upwards, it is in contact with the top end of the second slide groove 10. At this time, because the slider 12 is in contact with the second slide groove 10, the entire positioning plate 13 cannot move. Thus, the positioning process of the positioning plate 13 is completed by rotating the two swivel handles 15. Therefore, the positioning plate 13 will not be offset after positioning due to the friction between the slider 12 and the second slide groove 10.

[0029] Working principle: During use, the operator starts the deburring machine 1, and the grinding head inside the deburring machine 1 rotates. At this time, the gripper 8 is pulled to the right, which moves the connecting block 7 to the right. The connecting block 7 moves to the right, which stretches the telescopic spring 6. The mold is then placed inside the placement box 4 above the telescopic spring 6, and the gripper 8 is released. As the gripper 8 is released, the telescopic spring 6 retracts, which moves the connecting block 7 to the left. The connecting block 7 moves to the left, which moves the gripper 8 to the left, making it fit with the mold. Then, the adjusting block is pulled to make it fit with the mold, thus completing the mold positioning process. The gripper 8 clamps the mold, making the grinding process more stable. This eliminates the need for the operator to manually operate the mold during grinding, thus avoiding the problem of accidental injury to the operator when manually controlling the mold during grinding.

[0030] Finally, when the worker places the mold inside the placement box 4, he rotates the plum blossom handle 15 to separate it from the placement box 4. At this time, because the plum blossom handle 15 is separated from the placement box 4, the mounting block 14 can move. The movement of the mounting block 14 drives the positioning plate 13 to move, and the movement of the positioning plate 13 drives the slider 12 to slide on the surface of the circular rod 11. When both ends of the mold are in contact with the surface of the deburring machine 1 and the end face of the positioning plate 13 on which the silicone pad 16 is installed, the movement stops and the plum blossom handle 15 is rotated in the opposite direction so that the mounting block 14 can no longer move. The positioning plate 13 positions the mold that needs to be polished, so that the mold will not shift when it is polished. This makes the polishing process of the deburring machine 1 more stable and improves the quality of the mold after polishing.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
