Technical Field
[0001] This utility model relates to the field of mold surface treatment technology, and in particular to a mold surface treatment device. Background Technology
[0002] The external dimensions of the mold are determined according to the internal shape of the product. The mold is made of T10 material, which undergoes forging, heat treatment, machining, and surface treatment. After heat treatment to meet the required HRC (58-62), the surface is plated with hard chrome (0.2-0.6mm in diameter) to improve surface hardness and wear resistance, so that the mold quality meets production requirements and extends its service life.
[0003] Grinding and polishing is an important step in the surface treatment process of molds. Currently, there are two ways to perform grinding and polishing: one is fully automated mechanical grinding and polishing, and the other is manual grinding and polishing. However, due to cost issues and the complexity of molds, grinding and polishing of molds is still performed manually. With the iterative development of technology and the reduction of production costs, automated grinding of molds has become a trend.
[0004] Currently, automated grinding machines for molds have difficulty dealing with the holes in molds. They struggle to grind holes evenly and adapt to holes of different diameters. Therefore, a mold surface treatment device that can effectively grind and polish holes is needed to solve these problems. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a mold surface treatment device that can adjust the spacing between two first grinding strips, thereby allowing the first grinding strips to adapt to mold holes of different diameters. The symmetrically arranged two first grinding strips can achieve uniform grinding operation, thus achieving a good and efficient grinding effect.
[0006] The technical solution adopted to solve the above-mentioned technical problems is: a mold surface treatment device, including a frame, a robotic arm, a rotating rod, two telescopic rods, two first grinding strips, a drive ring, a rotating ring, and two push rods. The robotic arm performs multi-axis motion on the frame. The rotating rod is rotatably connected to the end of the robotic arm and is hollow. The two telescopic rods are respectively fixed to both sides of the rotating rod. The two first grinding strips correspond one-to-one with the telescopic rods and are fixedly connected to the ends of the telescopic rods. The drive ring is screwed onto the rotating rod, and the rotating ring is rotatably sleeved on the drive ring. The two push rods correspond one-to-one with the first grinding strips. The first end of the push rod is hinged to the first grinding strip, and the second end of the push rod is hinged to the rotating ring.
[0007] Furthermore, it also includes a push plate, an electric rod, two elastic steel bars, and an outlet. The push plate is slidably connected inside the rotating rod, the electric rod is connected inside the rotating rod, and the output end of the electric rod is fixedly connected to the push plate. The two elastic steel bars are respectively fixedly connected to the two sides below the push plate and are symmetrically arranged. The surface of the elastic steel bars is provided with a polishing layer. An outlet is opened on both sides of the lower end of the rotating rod, and the outlet is used to discharge the elastic steel bars.
[0008] Furthermore, it also includes an outgoing inclined block and an inclined surface. The outgoing inclined block is screwed to the lower end of the rotating rod. Inclined surfaces are provided on both sides of the outgoing inclined block. The inclined surfaces cooperate with the outlet and are used to outgoing the elastic steel bar at an angle.
[0009] Furthermore, it also includes a mounting groove and a second grinding strip. The mounting groove is provided on the lower side of the guide bevel block, and the second grinding strip is detachably connected to the mounting groove.
[0010] Furthermore, it also includes a support plate, a first motor, a first friction wheel, and a second friction wheel. The support plate is axially movably connected to the frame, the first motor is connected to the support plate, the first friction wheel is fixedly connected to the output shaft of the first motor, and the second friction wheel is coaxially fixedly connected to the drive ring.

[0011] Furthermore, it also includes a second motor and a mounting plate. The second motor is connected to the end of the robotic arm, the mounting plate is fixedly connected to the output shaft of the second motor, and the rotating rod is fixedly connected to the mounting plate.
[0012] The beneficial effects of this utility model are as follows: This utility model uses a rotating ring that rotates on a rotating rod to raise and lower the ring. The raising and lowering of the ring causes the rotating ring to move up and down, and the two push rods move under the drive of the rotating ring. This causes the two first grinding strips to move away from or towards each other. During this process, the telescopic rod extends or shortens to adjust the distance between the two first grinding strips, thus allowing the first grinding strips to adapt to mold holes of different diameters. The two symmetrically arranged first grinding strips can achieve uniform grinding operation, thereby achieving a good and efficient grinding effect. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] like Figures 1-5 As shown, this embodiment provides a mold surface treatment device, including a frame 1, a robotic arm 2, a rotating rod 3, two telescopic rods 4, two first grinding strips 5, a drive ring 6, a rotating ring 7, and two push rods 8. The robotic arm 2 performs multi-axis motion on the frame 1. The rotating rod 3 is rotatably connected to the end of the robotic arm 2 and is hollow. The two telescopic rods 4 are respectively fixed to both sides of the rotating rod 3. The two first grinding strips 5 correspond one-to-one with the telescopic rods 4 and are fixedly connected to the ends of the first grinding strips 5 and the ends of the telescopic rods 4. The drive ring 6 is screwed onto the rotating rod 3, and the rotating ring 7 is rotatably sleeved onto the drive ring 6. The two push rods 8 correspond one-to-one with the first grinding strips 5. The first end of the push rod 8 is hinged to the first grinding strip 5, and the second end of the push rod 8 is hinged to the rotating ring 7.
[0021] This invention utilizes a rotating ring 6 that rotates on a rotating rod 3 to raise and lower the ring 6. This movement causes the rotating ring 7 to move up and down, and the two push rods 8 move under the influence of the rotating ring 7. This causes the two first grinding strips 5 to move away from or closer to each other. During this process, the telescopic rod 4 extends or shortens to adjust the distance between the two first grinding strips 5, allowing the first grinding strips 5 to adapt to mold holes of different diameters. The symmetrically arranged first grinding strips 5 can achieve uniform grinding operation, thus achieving a good and efficient grinding effect.
[0022] Specifically, it also includes a push plate 9, an electric rod 10, two elastic steel bars 11, and an outlet 13. The push plate 9 is slidably connected to the inside of the rotating rod 3, the electric rod 10 is connected to the inside of the rotating rod 3, and the output end of the electric rod 10 is fixedly connected to the push plate 9. The two elastic steel bars 11 are respectively fixedly connected to the two sides below the push plate 9. The two elastic steel bars 11 are symmetrically arranged, and the surface of the elastic steel bars 11 is provided with a polishing layer 12. An outlet 13 is opened on both sides of the lower end of the rotating rod 3. The outlet 13 is used to discharge the elastic steel bars 11.
[0023] In the above embodiments, the electric rod 10 drives the push plate 9 to move down, and the push plate 9 moves down, causing the two elastic steel strips 11 to move down. The elastic steel strips 11 are discharged from the outlet 13. When the elastic steel strips 11 contact the bottom of the mold hole, the elastic steel strips 11 bend and fit against the bottom of the mold hole. When the rotating rod 3 rotates, the grinding operation at the bottom of the hole is realized.
[0024] Specifically, it also includes an outgoing inclined block 14 and an inclined surface 15. The outgoing inclined block 14 is screwed to the lower end of the rotating rod 3. Inclined surfaces 15 are provided on both sides of the outgoing inclined block 14. The inclined surfaces 15 cooperate with the outlet 13 and are used to outgoing the elastic steel strip 11 at an angle.
[0025] In the above embodiments, when the elastic steel strip 11 moves down and contacts the inclined surface 15 of the guide block 14, the inclined surface 15 acts on the elastic steel strip 11, so that the elastic steel strip 11 is led out from the outlet 13 in an inclined state, making it easier for the elastic steel strip 11 to bend and abut against the bottom of the mold hole.
[0026] Specifically, it also includes a mounting groove 16 and a second grinding strip 17. The mounting groove 16 is provided on the lower side of the guide bevel block 14, and the second grinding strip 17 is detachably connected to the mounting groove 16.
[0027] In the above embodiments, since the center of the hole cannot contact the polishing layer 12 after the two elastic steel strips 11 are bent, the second polishing strip 17 is rotated to cover it.
[0028] Specifically, it also includes a support plate 18, a first motor 23, a first friction wheel 19, and a second friction wheel 20. The support plate 18 is axially movably connected to the frame 1. The first motor 23 is connected to the support plate 18. The first friction wheel 19 is fixedly connected to the output shaft of the first motor 23. The second friction wheel 20 is coaxially fixedly connected to the driving ring 6. The first friction wheel 19 drives the second friction wheel 20 to rotate.
[0029] In the above embodiments, the first motor 23 rotates to drive the first friction wheel 19 to rotate, and controls the robotic arm 2 to make the first friction wheel 19 abut against the second friction wheel 20, thereby causing the drive ring 6 to rotate, and realizing the position adjustment operation of the first grinding strip 5.
[0030] Specifically, it also includes a second motor 21 and a mounting plate 22. The second motor 21 is connected to the end of the robotic arm 2, the mounting plate 22 is fixedly connected to the output shaft of the second motor 21, and the rotating rod 3 is fixedly connected to the mounting plate 22.
[0031] In the above embodiments, the second motor 21 drives the mounting plate 22 to rotate, which in turn drives the rotating rod 3 to rotate, thereby realizing the grinding operation.
[0032] The working principle of this utility model is as follows: First, adjust the distance between the two first grinding strips 5 according to the diameter of the hole, control the movement of the robotic arm 2 so that the rotating rod 3 is inserted into the mold hole, control the movement of the support plate 18 so that the first friction wheel 19 abuts against the second friction wheel 20, start the first motor 23 so that the first friction wheel 19 rotates, and after the second friction wheel 20 rotates, the driving ring 6 rotates, and the driving ring 6 moves up and down on the outside of the rotating rod 3. At this time, the rotating ring 7 and the driving ring 6 rotate relative to each other, and the push rod 8 drives the first grinding strips 5 on both sides to perform the first grinding. The first grinding strip 5 is in close contact with the side wall of the mold hole. Whether the first grinding strip 5 is in close contact with the inner wall of the hole can be determined by setting a pressure sensor at the first grinding strip 5. When the preset value is reached, the first motor 23 is stopped and the electric rod 10 is run. The electric rod 10 causes the push plate 9 to move down, and the push plate 9 causes the elastic steel strips 11 on both sides to move down. After the elastic steel strips 11 come into contact with the inclined surface 15 of the guide inclined block 14, the elastic steel strips 11 bend and tilt to be guided out until the elastic steel strips 11 abut against the bottom of the hole. Then the second motor 21 is run to make the rotating rod 3 rotate, so as to achieve uniform and efficient grinding operation.
