Description

Technical Field

[0001] The present invention relates to the technical field of mold processing, and specifically, it is a hole punching device for mold processing. Background Technique

[0002] Hole punching in mold processing is to rotate a drill bit on a mold part and make an axial feeding motion, and cut the material through the cutting edge of the drill bit to form a hole. It is applicable to processing holes of various diameters, especially for processing a large number of small and medium-diameter holes on mold parts, such as mounting holes and ejector pin holes of the mold.

[0003] For example, Chinese Patent Publication No.: CN215966424U discloses a hole punching device for mold processing, including a processing table, a transverse moving component for punching different positions of the mold, and a fixing component for preventing the mold from shaking. The transverse moving component includes a first chute opened on one side of the processing table, a first slider arranged in the first chute, a guiding groove opened on the other side of the processing table, a guiding block arranged in the guiding groove, a screw rod arranged in the first chute, a first motor connected to the screw rod, and a longitudinal moving component for punching different positions of the mold.

However, when punching the mold, the "pre-punching + reaming" method is often used for punching. In this solution, when replacing the drill rod, it is necessary to stop the machine for replacement, and when punching a through hole in the mold, it is necessary to stop the machine and use other tools to flip the mold.

[0028] Please refer to Figure 1 , in an embodiment of the present invention, a mold processing and drilling device includes a base 1, a bracket 2 is fixedly connected to the upper end of the base 1, a placement table 3 is fixedly connected to the middle of the upper end of the base 1, a three-axis module 6 is drivingly connected to the middle of the inner cavity of the bracket 2, a mounting frame 7 is drivingly connected to the lower part of the three-axis module 6, a drilling mechanism for drilling the mold is arranged on one side of the inner cavity of the mounting frame 7, and a conversion mechanism for replacing the drill bit is arranged in the middle of the inner cavity of the mounting frame 7. When the lower end of the electric push rod 11 is higher than the upper end surface of the conversion mechanism, the conversion mechanism rotates intermittently

[0029] Please refer to Figures 2-3, the punching mechanism includes an electric push rod 11. The outer wall of the electric push rod 11 is rotatably connected to the top of the inner cavity of the mounting frame 7. A driving motor 12 is drivingly connected to the center position of the top of the inner cavity of the mounting frame 7. A first gear 13 is fixedly connected to the output end of the driving motor 12. A second gear 14 is fixedly connected to the middle of the outer wall of the electric push rod 11. The first gear 13 and the second gear 14 are meshed with each other. That is, the driving motor 12 will drive the first gear 13 to rotate, and then drive the electric push rod 11 to rotate synchronously through the second gear 14. A clamping block 24 is fixedly connected to the bottom of the output end of the electric push rod 11. A magnet is embedded in the middle of the inner cavity of the clamping block 24.

[0030] The conversion mechanism includes a conversion cylinder 8. Symmetrical positioning rings 9 are rotatably connected to the outer wall of the conversion cylinder 8. The sides of the symmetrical positioning rings 9 away from the conversion cylinder 8 are fixedly connected to the side walls of the inner cavity of the mounting frame 7. A rotating rod 16 is fixedly connected to the middle of the upper end of the conversion cylinder 8. A mounting plate 15 is fixedly connected to the top of the rotating rod 16. The mounting plate 15 is fixedly connected to the side wall of one side of the inner cavity of the mounting frame 7. A third gear 17 is fixedly connected to the middle of the outer wall of the rotating rod 16. A servo motor 22 is drivingly connected to the side of the rotating rod 16 close to the electric push rod 11. A driving rod 21 is fixedly connected to the output end of the servo motor 22. A limiting plate 20 is movably connected to the outer wall of the driving rod 21. A limiting block 18 is fixedly connected to the side of the lower end of the limiting plate 20 close to the third gear 17. An incomplete gear 19 is arranged below the limiting block 18. The incomplete gear 19 is vertically and slidably connected to the outer wall of the rotating rod 16. That is, when the incomplete gear 19 is meshed with the third gear 17, the upper end surface of the clamping block 24 is in contact with the lower end surface of the incomplete gear 19. At this time, the clamping block 24 is located at the initial position along with the electric push rod 11. Then, when the servo motor 22 drives the driving rod 21 to rotate, the continuously rotating incomplete gear 19 will drive the third gear 17 to rotate intermittently.

[0031] Please refer to Figures 4-6, a plurality of symmetrically arranged placement holes 10 are provided in the inner cavity of the conversion cylinder 8. Fixed rings 41 are fixedly connected to both the upper and lower sides of the inner cavity of the placement hole 10. A magnet is arranged in the inner cavity of the upper fixed ring 41. In order to prevent the limit plate 20 and the limit block 18 from being affected by the rotation of the driving rod 21, a limit rod 23 is arranged between the limit plate 20 and the mounting plate 15. The upper end of the limit rod 23 is fixedly connected to the mounting plate 15. The lower end of the limit rod 23 is inserted into the inner cavities of the limit plate 20 and the limit block 18 and is vertically slidably connected to the limit plate 20 and the limit block 18. A spring is sleeved on the outer wall of the limit rod 23. The spring is located between the mounting plate 15 and the limit plate 20. When the electric push rod 11 drives the limit rod 23 to move down into the inner cavity of the placement hole 10, at this time, under the action of the elastic force, the incomplete gear 19, the limit block 18 and the limit plate 20 will drive the limit plate 20, the limit block 18 and the incomplete gear 19 to move down. While driving the incomplete gear 19 to separate from the third gear 17, the limit block 18 performs limit fixed connection on the third gear 17, thereby avoiding the conversion cylinder 8 from rotating due to vibration or other reasons during the process of punching the mold.

[0032] Please refer to Figure 6 , the lower end of the upper fixed ring 41 is magnetically connected to a mounting block 25. A card slot 40 is provided in the middle of the upper end of the mounting block 25. The size and shape of the card slot 40 are adapted to the card block 24. The lower end of the mounting block 25 is fixedly connected to a punching drill bit 26. The outer wall length of the card block 24 is less than the inner cavity interval of the fixed ring 41. Then when the electric push rod 11 drives the card block 24 to move down, the card block 24 will approach and be inserted into the card slot 40. Furthermore, the electric push rod 11 is used to push the mounting block 25 and the punching drill bit 26 to move down synchronously. Punching drill bits 26 with different lengths and widths are arranged in the inner cavity of the placement hole 10, and the vertical height between the punching drill bit 26 and the mounting block 25 is the same as the interval between the symmetric fixed rings 41. That is, when the length of the punching drill bit 26 becomes longer, the length of the mounting block 25 will be correspondingly shortened. As the card block 24 moves down, it will push the punching drill bit 26 to extend out of the lower end of the conversion cylinder 8 until the lower end of the mounting block 25 fits with the lower fixed ring 41 in the inner cavity of the placement hole 10. At this time, under the action of the three-axis module 6, the mounting frame 7 and the punching drill bit 26 can be driven to move on the x, y, and z axes, and then the mounting frame 7 and the punching drill bit 26 are synchronously driven to approach the mold. At this time, when the driving motor 12 drives the electric push rod 11 to rotate, the mounting block 25 and the punching drill bit 26 can be driven to rotate synchronously through the cooperation of the card block 24 and the card slot 40, thereby performing punching treatment on the mold.

[0033] Please refer to Figures 4-5, since the holes to be drilled in the mold have differences in depth and width, during the drilling process, it is necessary to continuously replace the drilling bits 26 with different lengths and widths to drill the mold. When the drill bit needs to be replaced, the electric push rod 11 drives the clamping block 24 to move upward, thereby driving the mounting block 25 and the drilling bit 26 to move upward synchronously into the placement hole 10. When the outer wall of the upper end of the mounting block 25 contacts the fixing ring 41 located above the inner cavity of the placement hole 10, the magnet in the fixing ring 41 will adsorb and fix the mounting block 25 at this time. If the clamping block 24 continues to rise with the electric push rod 11, the clamping block 24 will disengage from the inner cavity of the fixing ring 41 and then separate from the mounting block 25, enabling the mounting block 25 and the drilling bit 26 to stay stably in the placement hole 10. After the clamping block 24 drives the drilling bit 26 to move downward, the incomplete gear 19 disengages from the third gear 17, and the benefit of the limiting block 18 being engaged with the third gear 17 is that during the process of the drilling bit 26 rotating and drilling with the electric push rod 11, the vibration generated will inevitably be transmitted to the conversion cylinder 8 through the drilling bit 26, the mounting block 25, and the fixing ring 41 located below, which may cause the conversion cylinder 8 to shake and touch the outer wall of the electric push rod 11, affecting the drilling accuracy of the drilling bit 26. This situation can be avoided by clamping and limiting the third gear 17 with the limiting block 18.

[0034] After the clamping block 24 returns to its initial position with the electric push rod 11, it will lift the position of the incomplete gear 19 again. Since the shape and size of the teeth on the outer wall of the incomplete gear 19 are the same as those of the limiting block 18, when the teeth of the incomplete gear 19 approach the position of the third gear 17 at this time, the incomplete gear 19 can immediately mesh with the third gear 17 after moving upward, and there will be no situation where the teeth of the incomplete gear 19 touch the teeth of the third gear 17, affecting the upward movement of the incomplete gear 19. When the teeth of the incomplete gear 19 are far from the third gear 17, no matter where the teeth of the incomplete gear 19 are specifically located at this time, it will not affect the upward movement process of the incomplete gear 19. At this time, turn on the servo motor 22 to drive the driving rod 21 and the incomplete gear 19 to rotate, which can intermittently drive the placement hole 10 to rotate 45°, thereby rotating the placement hole 10 with different models of drilling bits 26 in its inner cavity to directly below the clamping block 24. At this time, the electric push rod 11 drives the clamping block 24 to move downward to complete the replacement of the drill bit. Moreover, during the drilling process of the new drilling bit 26, the limiting block 18 will limit the conversion cylinder 8 again. When the limiting block 18 moves downward and contacts the upper end surface of the third gear 17, it will stop moving downward. Therefore, the distance at which the limiting block 18 limits and fixes the third gear 17 is less than the distance between the clamping block 24 and the fixing ring 41 located above. Therefore, before the clamping block 24 contacts the mounting block 25, the limiting block 18 has already completed the limiting of the third gear 17, and thus limits and fixes the position state of the conversion cylinder 8.

[0035] For the mold, its surface is not a complete flat plane. To replace the product, some depressions or protrusions need to be created. Therefore, during the drilling process, when drilling a thin part, it can be drilled through directly. However, when creating a through hole in a thicker part, if only drilling from one side of the mold with a drill bit, there may be a risk of the drill bit breaking due to excessive drilling depth. To avoid this situation, in this solution, the mold is flipped 180° by a clamping member that can be flipped 180°, so as to drill from both sides of the mold and avoid the drill bit from breaking.

[0036] Please refer to Figure 7 , the clamping member includes an electric telescopic push rod 4. The bottom of the outer wall of the electric telescopic push rod 4 is attached to the middle part of the inner side of the bracket 2. The output end of the electric telescopic push rod 4 is fixedly connected with a fixture 5 (the fixture is a commonly used technical means for clamping and fixing workpieces in the prior art). The mold placed on the placing table 3 is clamped and fixed by the fixture 5. A rotating rod 30 is rotatably connected to the middle part of the outer wall of the electric telescopic push rod 4 on the side away from the fixture 5. A cavity 27 is opened on the side of the lower part of the bracket 2 close to the placing table 3. A transmission plate 28 is vertically slidably connected to the side of the inner cavity of the cavity 27 away from the placing table 3. The transmission plate 28 is slidably matched with the inner cavity of the bracket 2, that is, a groove for sliding the transmission plate 28 is opened in the inner cavity of the bracket 2. One end of the rotating rod 30 away from the electric telescopic push rod 4 is rotatably connected to the transmission plate 28. Symmetrical first vertical grooves 35 are opened on the side wall of the inner cavity of the cavity 27. An inclined groove 37 is opened on the side of the upper end of the first vertical groove 35 away from the placing table 3. A second vertical groove 36 is opened at one end of the inclined groove 37 away from the first vertical groove 35. A horizontal groove 39 is jointly opened between the lower ends of the second vertical groove 36 and the first vertical groove 35. A guide block 38 is elastically connected to the side of the inner cavity of the inclined groove 37 close to the second vertical groove 36. The end of the guide block 38 close to the inclined groove 37 is more closely attached to the side wall position of the inner cavity of the inclined groove 37.

[0037] Please refer to Figures 8-9, a driven gear 31 is slidably connected to the outer wall of the rotating rod 30. One end of the driven gear 31 close to the transmission plate 28 is rotatably connected to a circular ring 32. The circular ring 32 is sleeved on the outer wall of the rotating rod 30. The rotating rod 30 and the transmission plate 28 are slidably matched through symmetric balance rods. One end of the balance rod is fixedly connected to the circular ring 32 and the other end is slidably connected to the transmission plate 28. A spring is sleeved on the outer wall of the balance rod. Driven rods 33 are fixedly connected to both sides of the circular ring 32. The driven rods 33 are slidably matched with the inner cavities of the mounting block 25, the second vertical groove 36, the inclined groove 37 and the horizontal groove 39. Through the arrangement of the guiding block 38, when the driven rod 33 moves in the inner cavity of the inclined groove 37, when the driven rod 33 contacts the side of the guiding block 38 close to the inclined groove 37, at this time, the guiding block 38 will be squeezed by the driven rod 33 and thus retract into the inner cavity side wall of the inclined groove 37. After the driven rod 33 enters the inner cavity of the second vertical groove 36, the guiding block 38 pops out again under the action of elastic force. At this time, one end of the guiding block 38 close to the second vertical groove 36 will block the outer wall of the driven rod 33, so as to prevent the driven rod 33 from entering the inclined groove 37 again due to elastic force. When the driven rod 33 moves to the connection of the second vertical groove 36 and the horizontal groove 39, at this time, under the action of elastic force, it will drive the driven rod 33 to the bottom of the inner cavity of the first vertical groove 35.

[0038] Please refer to Figures 8-10, on the side of the inner cavity of the cavity 27 away from the transmission plate 28, a rack 34 is fixedly connected. The upper end surface of the rack 34 is lower than the plane where the top of the first vertical groove 35 is located. When the driven rod 33 is located in the inner cavity of the first vertical groove 35, the position of the rack 34 corresponds to the position of the driven gear 31. The three-axis module 6 includes an x-axis, a y-axis, and a z-axis. In this solution, both ends of the x-axis of the three-axis module 6 are fixedly connected with transmission rods 29. The outer wall of the end of the transmission rod 29 away from the x-axis is slidably matched with the middle part of the upper end of the transmission plate 28. The outer wall of the transmission rod 29 is slidably matched with the bracket 2, that is, a chute for slidably matching with the transmission rod 29 is opened in the middle part of the upper end of the transmission plate 28. That is, when the three-axis module 6 drives the drilling bit 26 to move downward, at this time, the transmission rod 29 moves downward along the inner cavity of the chute, and during this process, the transmission plate 28 remains stationary. When the three-axis module 6 drives the drilling bit 26 to move upward, after the transmission rod 29 moves upward to the top of the inner cavity of the chute, it will drive the transmission plate 28 to move upward synchronously, thereby driving the rotating rod 30, the electric telescopic push rod 4, and the fixture 5 to move upward, and further driving the mold to move upward. When the rotating rod 30 moves upward, it will drive the driven gear 31, the ring 32, and the driven rod 33 to move upward synchronously, so that the driven gear 31 contacts the rack 34, and under the transmission cooperation of the rack 34 and the driven gear 31, the rotating rod 30, the electric telescopic push rod 4, the fixture 5, and the mold are driven to rotate 180° synchronously, thus completing the flipping of the mold. And during the continuous upward movement of the transmission plate 28, the driven rod 33 will pass through the inclined groove 37 from the inner cavity of the first vertical groove 35 and enter the inner cavity of the second vertical groove 36. Then the transmission plate 28 stops moving upward and will move downward and reset along with the transmission rod 29. And when the driven rod 33 moves from the first vertical groove 35 to the second vertical groove 36, the driven gear 31 and the rack 34 will be separated, so as to avoid the driven gear 31 contacting the rack 34 again during the downward movement, which would cause the mold to flip back. The advantage of the upper end surface of the rack 34 being lower than the plane where the top of the first vertical groove 35 is located is that during the process of the driven rod 33 moving from the bottom of the first vertical groove 35 to the top of the inner cavity of the first vertical groove 35, after the driven gear 31 rotates 180° and is separated from the rack 34, the driven rod 33 will enter the inclined groove 37. After the mold is flipped to ensure a stable state, the driven gear 31 is far away from the position where the rack 34 is located in both the vertical direction and the horizontal direction, thus avoiding secondary contact between the driven gear 31 and the rack 34 and the position state of some molds after flipping.
