Description

Technical Field

[0001] This invention relates to the field of mold drilling, specifically to a cantilever drilling machine for mold drilling. Background Technology

[0002] Drilling is the most basic and widely used cutting process in mold manufacturing. It runs through the entire process of mold frame and cavity plate processing. It mainly processes threaded bottom holes, ejector pin assembly holes, locating pin holes, cooling water holes, electric heating tube mounting holes, etc. The quality of hole processing directly determines the mold assembly accuracy, mold opening and closing smoothness and heat dissipation effect.

[0003] Cantilever drilling machines are commonly used drilling equipment in mold workshops. Relying on a cantilever spindle structure that can move flexibly forward, backward, left, and right, they eliminate the need for frequent movement of heavy mold plates, making them ideal for drilling various holes in large and medium-sized molds and frames. Compared to bench drills, they have a wider stroke range, allowing them to accommodate larger injection molds and stamping templates. They are mainly used to process holes with moderate precision requirements, such as threaded bottom holes, fastening screw holes, shallow water passage holes, and process through holes. When machining mold workpieces using a cantilever drilling machine, the mold plate is first firmly and securely pressed onto the worktable. A center drill is used for pre-marking positioning to prevent slippage and deviation during twist drill cutting. The drill bit is matched according to the mold steel material; cobalt-containing drill bits are often used for machining pre-hardened mold steel. Cutting fluid is applied throughout the process for cooling and chip removal.

[0004] After existing cantilever drilling machines complete the drilling of mold steel, the hard steel chips, fine and long coiled iron chips, and cutting fluid mixed with iron chips produced cannot be automatically collected. The industry generally uses workers to use handheld air guns to blow air to clean the worktable, mold plate surface, and equipment surface. The high-pressure air blowing is an irregular blowing operation. The high-pressure airflow will blow the fine steel chips and iron powder on the worktable and mold surface into the surrounding area of ​​the equipment and into the air of the workshop, forming suspended iron chip dust, which not only seriously pollutes the workshop working environment, but is also easily inhaled by operators, damaging their occupational health. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a cantilever drilling machine for drilling molds, so as to solve the technical problems in the background art mentioned above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cantilever drilling machine for drilling molds, comprising a base, a cantilever body, and a collection groove, wherein the cantilever body is mounted on the upper end of the base, and the collection groove is provided on the upper end of the base;

[0007] A support is installed inside the collection tank. A placement seat is movably installed on the upper end of the support. A first support seat and a second support seat are installed on the upper end of the base. A limiting post is movably installed between the first support seat and the second support seat, and the outer wall of the limiting post is fixedly connected to the inner wall of the placement seat. Support blocks are installed on the inner walls of both the first support seat and the second support seat, and the outer walls of the two sets of support blocks are movably connected to the outer walls of both ends of the limiting post. Multiple sets of limiting blocks are installed on one end of the limiting post. A limiting ring is movably installed inside the second support seat, and the outer wall of the limiting ring is movably connected to the outer walls of the multiple sets of limiting blocks.

[0008] The upper end of the base is provided with a second sliding groove, and a second connecting shaft is movably installed inside the second sliding groove. A connecting rod is movably installed on the outer wall of the second connecting shaft. A second scraper is installed at one end of the connecting rod, and the outer wall of the second scraper is movably connected to the outer wall of the placement seat.

[0009] By adopting the above technical solution, the problem of difficult-to-remove rolled iron filings and cutting oil stains adhering to the surface of the placement seat, which previously relied on air gun cleaning, is solved. The support block drives the limiting column to move, so that two of them engage with the limiting ring. The limiting ring rotates, causing the limiting column and the placement seat to flip 90 degrees. Then the placement seat falls back to the upper end of the support. The second scraper cleans the outer wall of one side of the placement seat after it has flipped over. Impurities on the placement surface can be automatically cleaned simultaneously with drilling operations. The debris is collected and recycled in a unified manner, reducing environmental pollution in the workshop and reducing the workload of the staff.

[0010] The present invention is further configured such that two sets of movable cylinders are installed inside the base, and the two sets of movable cylinders are connected by a toothed synchronous belt. A first drive motor is installed inside the base, and one end of one set of movable cylinders is connected to the output end of the first drive motor.

[0011] Preferably, the first drive motor is started to drive a set of movable cylinders to rotate. The two sets of movable cylinders are connected by a toothed synchronous belt, so the two sets of movable cylinders rotate synchronously.

[0013] Preferably, the two sets of movable cylinders rotate synchronously, and the inner walls of the two sets of movable cylinders are respectively threaded to the outer walls of the two sets of telescopic columns. Therefore, the two sets of telescopic columns move upward, thereby driving the two sets of support blocks to move upward.

[0014] The present invention is further configured such that a limiting groove is formed at the upper end of a set of the support blocks, a reserved groove is formed on the inner wall of the second support seat, and the outer walls of the multiple sets of limiting blocks are respectively movably connected to the inner walls of the limiting groove and the reserved groove.

[0017] Preferably, the second drive motor starts and drives the first drive shaft to rotate, which in turn drives the first drive bevel gear to rotate. The first drive bevel gear meshes with the transmission bevel gear, so the transmission bevel gear rotates, which in turn drives the transmission shaft to rotate.

[0018] The present invention is further configured such that a speed-changing gearbox is installed inside the base, and one end of the speed-changing gearbox extends into the interior of the second support base. An input shaft is installed at the input end of the speed-changing gearbox, and a toothed synchronous belt is provided between the input shaft and the transmission shaft. An output shaft is installed at the output end of the speed-changing gearbox, and an output gear is installed at one end of the output shaft.

[0019] Preferably, the drive shaft rotates, and the drive shaft is connected to the input shaft by a toothed synchronous belt. Therefore, when the input shaft rotates, it transmits rotational kinetic energy to the inside of the gearbox. After the gearbox reduces the speed, the rotational kinetic energy is transmitted to the output shaft, which then rotates, driving the output gear to rotate.

[0020] The present invention is further configured such that a limiting disk is movably installed inside the second support base, a toothed ring is installed in a groove at the bottom end of the limiting disk, and the toothed ring is meshed with the output gear, and a connecting plate is installed at one end of the limiting disk, and one end of the connecting plate is connected to the limiting ring.

[0021] Preferably, the output gear rotates and meshes with the gear ring, so the gear ring rotates slowly, thereby driving the limiting disk to rotate slowly, and in turn driving the limiting ring to rotate slowly.

[0022] The present invention is further configured such that a first sliding groove is provided at the upper end of the base, a first connecting shaft is movably installed inside the first sliding groove, and one end of the first connecting shaft is connected to the transmission shaft by a toothed synchronous belt. A first scraper is mounted on the upper end of the collection groove, and the inner wall of one end of the first scraper is threadedly connected to the outer wall of the first connecting shaft. The outer wall of the first scraper is movably connected to the outer wall of the support.

[0023] Preferably, the drive shaft rotates, and the drive shaft is connected to the first connecting shaft by a toothed synchronous belt, so the first connecting shaft rotates. The outer wall of the first connecting shaft is threadedly connected to the inner wall of one end of the first scraper, so the first scraper is displaced.

[0027] Preferably, the second driving bevel gear rotates and meshes with the connecting bevel gear, so the connecting bevel gear rotates, thereby driving the second connecting shaft to rotate. The reciprocating thread groove on the outer wall of the second connecting shaft is movably connected to the protrusion on the inner wall of one end of the connecting rod, so the connecting rod reciprocates.

[0028] In summary, the present invention has the following main beneficial effects:

[0029] 1. This invention, by incorporating a support block, a limiting post, a limiting ring, and a second scraper, solves the problem of difficult-to-remove rolled iron filings and cutting oil stains adhering to the surface of the placement seat, which previously relied on air gun cleaning. The support block drives the limiting post to move, causing two sets of them to engage with the limiting ring. The limiting ring rotates, causing the limiting post and placement seat to flip 90 degrees. Then, the placement seat falls back to the upper end of the support. The second scraper reciprocates to clean the outer wall of one side of the placement seat after it has flipped. This allows for the automatic cleaning of impurities on the placement surface during drilling operations, with debris collected and recycled in a unified manner, reducing environmental pollution in the workshop and lowering the workload of workers.

[0030] 2. This invention, by setting up a support block, a limiting post, a limiting block, a limiting ring, and a first scraper, allows the support block to drive the limiting post to move, so that two sets of them engage with the limiting ring. The limiting ring rotates, causing the limiting post and the placement seat to flip 90 degrees. At the same time, the first scraper moves synchronously, automatically scraping away and cleaning the iron filings and impurities that fall and accumulate on the upper end of the support, replacing the manual air gun cleaning method. It can uniformly guide the waste falling off the flipped side into the collection tank for collection, avoiding the accumulation of iron filings and embedding in the guide rail, which would cause equipment wear. It also prevents iron filings from splashing and scratching the mold surface, greatly reducing the amount of manual cleaning work, and improving the drilling accuracy of the mold and the stability of equipment operation.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] The embodiments of the present invention will now be described.

[0046] A cantilever drilling machine for drilling holes in molds, such as Figure 1 - Figure 11 As shown, it includes a base 1, a cantilever body 2, and a collection trough 3. The cantilever body 2 is installed on the upper end of the base 1, and the collection trough 3 is opened on the upper end of the base 1.

[0047] A support 4 is installed inside the collection tank 3. A placement seat 5 is movably installed on the upper end of the support 4. A first support seat 8 and a second support seat 14 are installed on the upper end of the base 1. A limiting post 6 is movably installed between the first support seat 8 and the second support seat 14. The outer wall of the limiting post 6 is fixedly connected to the inner wall of the placement seat 5. Support blocks 12 are installed on the inner walls of the first support seat 8 and the second support seat 14. The outer walls of the two sets of support blocks 12 are movably connected to the outer walls of the two ends of the limiting post 6. Multiple sets of limiting blocks 7 are installed on one end of the limiting post 6. A limiting ring 18 is movably installed inside the second support seat 14. The outer wall of the limiting ring 18 is movably connected to the outer walls of the multiple sets of limiting blocks 7.

[0048] The upper end of the base 1 is provided with a second sliding groove 32. A second connecting shaft 36 is movably installed inside the second sliding groove 32. A connecting rod 38 is movably installed on the outer wall of the second connecting shaft 36. A second scraper 39 is installed at one end of the connecting rod 38, and the outer wall of the second scraper 39 is movably connected to the outer wall of the placement seat 5.

[0049] Please see Figure 4 - Figure 5 The base 1 has two sets of movable cylinders 10 installed inside, and the two sets of movable cylinders 10 are connected by a toothed synchronous belt. The base 1 has a first drive motor 9 installed inside, and one end of one set of movable cylinders 10 is connected to the output end of the first drive motor 9. When the first drive motor 9 is started, it drives one set of movable cylinders 10 to rotate. The two sets of movable cylinders 10 are connected by a toothed synchronous belt, so the two sets of movable cylinders 10 rotate synchronously.

[0050] Please see Figure 4 - Figure 5 Both sets of movable cylinders 10 have telescopic columns 11 movably installed on their inner walls, and the outer walls of the two sets of telescopic columns 11 are threadedly connected to the inner walls of the two sets of movable cylinders 10 respectively. One end of each set of telescopic columns 11 is connected to one set of support blocks 12 respectively. The two sets of movable cylinders 10 rotate synchronously. Since the inner walls of the two sets of movable cylinders 10 are threadedly connected to the outer walls of the two sets of telescopic columns 11 respectively, the two sets of telescopic columns 11 move upward, thereby driving the two sets of support blocks 12 to move upward.

[0051] Please see Figure 4 - Figure 5 A set of support blocks 12 has a limit groove 13 on its upper end, and a reserved groove 15 is provided on the inner wall of the second support base 14. The outer walls of multiple sets of limit blocks 7 are movably connected to the inner walls of the limit groove 13 and the reserved groove 15 respectively. The setting of the limit groove 13 and the reserved groove 15 avoids the limit block 7 from shifting and causing interference.

[0052] Please see Figure 2 - Figure 9 A second drive motor 24 is installed on the upper end of the base 1. A first drive shaft 25 is installed at the output end of the second drive motor 24. A first drive bevel gear 26 is installed at one end of the first drive shaft 25. A transmission shaft 27 is movably installed inside the base 1. A transmission bevel gear 28 is installed at one end of the transmission shaft 27, and the transmission bevel gear 28 is meshed with the first drive bevel gear 26. When the second drive motor 10 starts, it drives the first drive shaft 25 to rotate, thereby driving the first drive bevel gear 26 to rotate. The first drive bevel gear 26 is meshed with the transmission bevel gear 28, so the transmission bevel gear 28 rotates, thereby driving the transmission shaft 27 to rotate.

[0053] Please see Figure 8 - Figure 9 The base 1 houses a gearbox 20, with one end extending into the second support 14. The gearbox 20 has an input shaft 21 at its input end, connected to the transmission shaft 27 by a toothed synchronous belt. The gearbox 20 also has an output shaft 22 at its output end, with an output gear 23 mounted at one end. The transmission shaft 27 rotates, and the input shaft 21 is connected to the input shaft 21 via the toothed synchronous belt. Therefore, the input shaft 21 rotates, transmitting rotational kinetic energy to the gearbox 20. After reducing the speed, the gearbox 20 transmits the rotational kinetic energy to the output shaft 22, causing it to rotate and drive the output gear 23 to rotate.

[0054] Please see Figure 6 - Figure 8 The second support base 14 has a movably mounted limiting plate 16 inside. The bottom end of the limiting plate 16 has a groove for mounting a gear ring 19, which meshes with the output gear 23. One end of the limiting plate 16 has a connecting plate 17, which is connected to the limiting ring 18. When the output gear 23 rotates, it meshes with the gear ring 19, causing the gear ring 19 to rotate slowly, which in turn drives the limiting plate 16 to rotate slowly, and in turn drives the limiting ring 18 to rotate slowly.

[0055] Please see Figure 1 - Figure 10The base 1 has a first sliding groove 29 on its upper end. A first connecting shaft 30 is movably installed inside the first sliding groove 29. One end of the first connecting shaft 30 is connected to the transmission shaft 27 by a toothed synchronous belt. A first scraper 31 is mounted on the upper end of the collection tank 3. The inner wall of one end of the first scraper 31 is threadedly connected to the outer wall of the first connecting shaft 30. The outer wall of the first scraper 31 is movably connected to the outer wall of the support 4. The transmission shaft 27 rotates. The transmission shaft 27 and the first connecting shaft 30 are connected by a toothed synchronous belt. Therefore, the first connecting shaft 30 rotates. The outer wall of the first connecting shaft 30 is threadedly connected to the inner wall of one end of the first scraper 31. Therefore, the first scraper 31 is displaced.

[0056] Please see Figure 2 - Figure 11 A third drive motor 33 is installed on the upper end of the base 1. A second drive shaft 34 is installed at the output end of the third drive motor 33. A second drive bevel gear 35 is installed at one end of the second drive shaft 34. When the third drive motor 33 is started, it drives the second drive shaft 34 to rotate, thereby driving the second drive bevel gear 35 to rotate.

[0057] Please see Figure 11 A connecting bevel gear 37 is installed at one end of the second connecting shaft 36, and the connecting bevel gear 37 is meshed with the second driving bevel gear 35. The outer wall of the second connecting shaft 36 is provided with a reciprocating threaded groove, and one end of the connecting rod 38 is provided with a protrusion that is movably connected to the reciprocating threaded groove. When the second driving bevel gear 35 rotates, it meshes with the connecting bevel gear 37, so the connecting bevel gear 37 rotates, thereby driving the second connecting shaft 36 to rotate. The reciprocating threaded groove on the outer wall of the second connecting shaft 36 is movably connected to the protrusion on the inner wall of one end of the connecting rod 38, so the connecting rod 38 reciprocates.

[0058] The working principle of this invention is as follows: After the worker completes drilling a set of molds through the cantilever body 1, the worker takes the molds from the upper end of the placement seat 5 to the placement area. Then, the worker starts the first drive motor 9, which drives a set of movable cylinders 10 to rotate. The two sets of movable cylinders 10 are connected by a toothed synchronous belt, so the two sets of movable cylinders 10 rotate synchronously. The inner walls of the two sets of movable cylinders 10 are threadedly connected to the outer walls of the two sets of telescopic columns 11, so the two sets of telescopic columns 11 move upward, thereby driving the two sets of support blocks 12 to move upward. The two sets of support blocks 12 drive the two ends of the limiting column 6 to move upward, thereby driving the placement seat 5 to move upward. One set of support blocks 12 continuously drives one end of the limiting column 6 to move upward, so that the limiting ring 18 enters between the two sets of limiting blocks 7. Then, the first drive motor 10 is turned off.

[0059] When the first drive motor 10 is turned off, the second drive motor 10 starts, driving the first drive shaft 25 to rotate, which in turn drives the first drive bevel gear 26 to rotate. The first drive bevel gear 26 meshes with the transmission bevel gear 28, so the transmission bevel gear 28 rotates, which in turn drives the transmission shaft 27 to rotate. The transmission shaft and the input shaft 21 are connected by a toothed synchronous belt, so the input shaft 21 rotates. The input shaft 21 transmits rotational kinetic energy to the inside of the gearbox 20. After the gearbox 20 reduces the speed, the rotational kinetic energy is transmitted to the output shaft 22. The output shaft 22 rotates, driving the output gear 23 to rotate. The output gear 23 meshes with the gear ring 19, so the gear ring 19 rotates slowly, which drives the limiting disk 16 to rotate slowly, which in turn drives the limiting ring 18 to rotate slowly, and then drives the limiting post 6 and the placement seat 5 to rotate. The limiting post 6 and the placement seat 5 finally rotate at a 90-degree angle, changing the placement surface of the placement seat 5 for the next set of mold processing.

[0060] When the drive shaft 27 rotates, the drive shaft 27 is connected to the first connecting shaft 30 through a toothed synchronous belt. Therefore, the first connecting shaft 30 rotates. The outer wall of the first connecting shaft 30 is threadedly connected to the inner wall of one end of the first scraper 31. Therefore, the first scraper 31 is displaced. The first scraper 31 cleans up the impurities that fall to the upper end of the support 4 when the placement seat 5 rotates, so that the impurities at the upper end of the support 4 fall into the collection tank 3.

[0061] When the limiting post 6 and the placement seat 5 are rotated 90 degrees, the first drive motor 9 starts and drives the movable cylinder 10 to rotate in the opposite direction. At the same time, the second drive motor 24 drives the first drive shaft 25 to rotate in the opposite direction. The two ends of the limiting post 6 move downward with the two sets of support blocks 12, and the multiple sets of limiting blocks 7 separate from the limiting ring 18. The placement seat 5 moves towards the support 4. At the same time, the limiting ring 18 and the first scraper 31 reset.

[0062] After the placement seat 5 is placed on the upper end of the support 4, the worker places a set of molds to be processed on the upper end of the placement surface after the placement seat 5 is replaced. Then, the worker drills holes in the molds through the cantilever body 1. At the same time, the third drive motor 33 starts, driving the second drive shaft 34 to rotate, which in turn drives the second drive bevel gear 35 to rotate. The second drive bevel gear 35 is meshed with the connecting bevel gear 37, so the connecting bevel gear 37 rotates, which in turn drives the second connecting shaft 36 to rotate. The reciprocating thread groove on the outer wall of the second connecting shaft 36 is movably connected to the protrusion on the inner wall of one end of the connecting rod 38, so the connecting rod 38 moves back and forth, which in turn drives the second scraper 39 to move. The second scraper 39 rotates the placement seat 5 to one side of the placement surface for cleaning, so that the impurities adhering to the outer wall of one side of the placement seat 5 fall into the inner wall of the collection tank 3. A drain pipe can be provided at one end of the collection tank 3 to discharge the impurities.
