Description

Technical Field

[0001] This utility model relates to the field of mold trimming devices, and in particular to a high-precision mold manufacturing and processing trimming device. Background Technology

[0002] The production of high-precision molds is inseparable from efficient edge-cutting devices. These specialized devices play a crucial role in the mold processing process. Through precise mechanical structures and cutting tools, they accurately cut the edges of the mold to remove excess material or waste, thereby ensuring that the mold edges meet predetermined precision and flatness standards.

[0003] However, traditional edge-cutting devices often face some limitations. Their edge-cutting blades are fixed and cannot flexibly meet the diverse edge-cutting needs of various molds. This limits the versatility and operational flexibility of the equipment to a certain extent. In addition, after the edge-cutting operation is completed, waste material edges often adhere to the mold surface. This not only increases the difficulty of manual cleaning but also significantly reduces the overall work efficiency. More troublesome is that in the subsequent demolding process of high-precision molds, the large adhesion between the mold and the waste material often makes the demolding process very difficult.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0015] This invention features a cutting assembly powered by a hydraulic cylinder. The design incorporates a two-way lead screw and clamps, allowing for adjustable distance between the clamps. This facilitates the replacement of cutting blades of different sizes to meet the cutting requirements of various materials, demonstrating high flexibility. Meanwhile, the anti-slip texture on the clamps increases friction with the cutting blades, effectively preventing slippage or deviation during the cutting process and ensuring the stability and reliability of the cutting.

[0016] This invention, through the combination of a waste processing component, a telescopic cylinder, and a support column, enables the automatic sliding and collection of waste. After the cutting is completed, the waste can be discharged from the platform without manual intervention, greatly improving work efficiency and automation.

[0017] This invention, through the installation of a demolding assembly, uses a second motor to drive a rotating shaft to rotate, positioning a second mounting plate below the cutting blade. The cutting blade is then released via a clamp, allowing it and the internal mold to be placed on pads on both sides of the second mounting plate, thus elevating the cutting blade for easier demolding. Next, the second motor drives the first rotating shaft, rotating the second mounting plate below the sprayer. The sprayer ensures the release agent is evenly sprayed onto the mold surface, reducing adhesion between the mold and the cutting blade and improving the automation level of demolding. Finally, the second motor drives the first rotating shaft below the demolding pressure plate, and the telescopic cylinder... The four-drive lifting guide column descends, causing the demolding pressure plate to push the mold downwards, allowing the mold to be demolded smoothly. Finally, the second motor drives the first rotating shaft to rotate, positioning the second mounting plate below the clamping seat. The bidirectional lead screw rotates, causing the clamping seat to clamp the cutting blade appropriately and rise. The demolded mold is now located on the second mounting plate, and the cutting blade returns to the clamping seats, allowing for the cutting operation of the next mold. This improves the automation level of demolding, reduces manual operation, and increases work efficiency. The demolding pressure plate can be removed from the long bolt by rotation, and the demolding pressure plate corresponding to the mold can be flexibly replaced to adapt to the demolding requirements of different molds.

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0027] like Figures 1-7 As shown, the present invention proposes a high-precision mold manufacturing and processing edge trimming device, which includes a mounting frame 1, an edge trimming component 2 disposed on one side of the mounting frame 1, a waste material processing component 3 disposed on one side of the bottom of the mounting frame 1, the waste material processing component 3 being located directly below the edge trimming component 2, and a demolding component 4 disposed on the side of the mounting frame 1 away from the edge trimming component 2.

[0028] Mounting frame 1 includes a base 12, with support feet 11 around the bottom of the base 12. Several columns 13 are mounted on the base 12, and a top plate 14 is mounted on the top of the columns 13. Mounting frame 1 is the skeleton of the entire equipment. The base 12, columns 13 and top plate 14 form a stable support structure to support and fix the cutting component 2, waste handling component 3 and demolding component 4. The base 12 serves as the supporting foundation of the entire equipment. It provides stable support force by contacting the ground through the support feet 11 around its perimeter, ensuring that the equipment does not shake during operation.

[0029] The trimming assembly 2 includes a hydraulic cylinder 21 located at the bottom of the top plate 14. The hydraulic cylinder 21 provides power to drive the telescopic rod to move up and down, thereby driving the trimming blade 25 to perform trimming operations. A mounting plate 22 is located at the bottom of the telescopic rod of the hydraulic cylinder 21. A slide rail groove 210 is opened at the bottom of the mounting plate 22. A motor 26 is located on one side of the mounting plate 22. A fixed cylinder 28 is located on the side of the mounting plate 22 away from the motor 26. A bidirectional lead screw 29 is inserted in the fixed cylinder 28. The side of the bidirectional lead screw 29 away from the fixed cylinder 28 is connected to the transmission end of the motor 26. The bidirectional lead screw 29 is located in the slide rail groove 210. Driven by the motor 26, the bidirectional lead screw 29 rotates, causing the two clamps 24 to move relative to or towards each other in the slide rail groove 210. By adjusting the distance between the two clamps 24, the trimming blade 25 can be replaced to adapt to the trimming requirements of different molds.

[0030] A pair of clamps 24 are symmetrically arranged on both sides inside the slide rail groove 210. The two clamps 24 are threaded and movably sleeved on the bidirectional lead screw 29. A pair of guide rails 23 are symmetrically arranged on the mounting plates 22 on both sides of the slide rail groove 210. The clamps 24 have guide rail grooves corresponding to the positions of the guide rails 23. Anti-slip texture 27 is provided on one side of the clamps 24. A cutting blade 25 is movably arranged between the two clamps 24. The two clamps 24 are used to fix the cutting blade 25 and increase the friction through the anti-slip texture 27 to ensure stable cutting.

[0031] Waste handling assembly 3 includes a discharge plate 31 disposed within base 12. The discharge plate 31 serves as a channel for waste to slide out, guiding the waste generated during trimming to a designated position. A pair of telescopic cylinders 32 are symmetrically arranged on base 12. A platform 39 is mounted on the top of the telescopic rods of the two telescopic cylinders 32. The two telescopic cylinders 32 are located on one side of the bottom of the platform 39. During trimming, the telescopic cylinders 32 provide support for the platform 39. After trimming, the two telescopic cylinders 32 lift one side of the platform 39, tilting it and allowing the waste to slide off. A pair of support columns are symmetrically arranged on base 12. 311, Two support columns 311 are located at the bottom of the platform 39 on the side away from the telescopic cylinder 32. Each of the two support columns 311 is equipped with a connector 312 at the top. A pair of upright ears 313 are symmetrically arranged at the bottom of the platform 39. The connector 312 is movably connected to the upright ears 313. The support columns 311 provide support for the platform 39 to ensure the stability of the platform 39. The connector 312 at the top of the support column 311 is movably connected to the upright ears 313 at the bottom of the platform 39. The combination of the connector 312 and the upright ears 313, together with the telescopic cylinder 32, raises one side of the platform 39, allowing the waste material to slide off smoothly.

[0032] A pair of telescopic cylinders 34 are symmetrically arranged on the base 12. The top of the telescopic rods of the two telescopic cylinders 34 are equipped with pressing plates 310. The pressing plates 310 are located directly above the platform 39. The telescopic cylinders 34 drive the pressing plates 310 to rise and fall. The pressing plates 310 can press down the waste material edge of the mold to be cut. After the cutting is completed, the cutting blade 25 rises and presses down the waste material through the pressing plates 310, so that the waste material is separated from the mold.

[0033] The demolding assembly 4 includes a bearing seat 43 located at the bottom of the top plate 14. A rotating shaft 42 is installed inside the bearing seat 43, which supports the rotating shaft 42 and enables it to rotate stably. A motor 41 is installed at the bottom of the base 12. The end of the rotating shaft 42 away from the bearing seat 43 is connected to the transmission end of the motor 41. A mounting plate 44 is installed on one side of the rotating shaft 42. A pair of pads 45 are symmetrically arranged on both sides of the mounting plate 44. The rotating shaft 42 is driven to rotate by the motor 41, which drives the mounting plate 44 to rotate to the position below the sprayer 414 and the demolding pressure plate 411 of the trimming assembly 2 and the demolding assembly 4. The pads 45 can raise the trimming blade 25 to assist demolding.

[0034] A pair of guide post sleeves 46 are provided on the side of bearing housing 43 away from hydraulic cylinder 21. The two guide post sleeves 46 are located at the bottom of top plate 14. Telescopic cylinder 47 is provided inside the guide post sleeves 46. Lifting guide post 48 is provided at the top of the telescopic rod of telescopic cylinder 47. Lifting guide post 48 is located inside the guide post sleeves 46. Mounting block 49 is provided at the bottom of lifting guide post 48. Long bolt 410 is provided at the bottom of mounting block 49. Demolding pressure plate 411 is spirally provided at the bottom of long bolt 410. Demolding pressure plate 411 can be removed by rotating and replaced with demolding pressure plate 411 corresponding to the mold. The guide post sleeves 46 provide guidance for lifting guide post 48. Telescopic cylinder 47 drives lifting guide post 48 to rise and fall, thereby adjusting the height of demolding pressure plate 411 and demolding the mold.

[0035] A pipe 412 is provided at the bottom of the top plate 14 corresponding to the position of the second mounting plate 44. A mold release agent inlet pipe 413 is provided on one side inside the top plate 14. The first pipe 412 is connected to the mold release agent inlet pipe 413. A sprayer 414 is provided at the bottom of the first pipe 412. The sprayer 414 is connected to the mold release agent inlet pipe 413 through the first pipe 412. It is used to spray mold release agent before demolding to reduce the adhesion between the cutting blade 25 and the mold and facilitate demolding.

[0036] When using it, the user first prepares by selecting the corresponding cutting blade 25 and demolding plate 411 according to the mold to be cut, starting the motor 26, driving the two clamps 24 to clamp the cutting blade 25 appropriately, and rotating and fixing the demolding plate 411 to the bottom of the long bolt 410. Finally, the user fixes the mold to be cut in the middle of the platform 39.

[0037] When the trimming device is working, firstly, the telescopic cylinder 34 drives the pressure plate 310 to descend, pressing down the waste edge of the mold to be trimmed. Then, the hydraulic cylinder 21 drives the trimming blade 25 to descend, performing the trimming action on the mold. After the trimming is completed, the trimming blade 25 rises. At this time, the mold after trimming will rise along with the trimming blade 25 due to the adhesion force, while the waste edge is pressed down by the pressure plate 310, causing the mold to separate from the waste edge, and the waste edge remains on the platform 39.

[0038] When the mold is demolded, motor 2 41 drives shaft 1 42 to rotate, so that mounting plate 2 44 is directly below the cutting blade 25. Motor 1 26 drives the bidirectional lead screw 29 to rotate, so that clamp 24 releases the cutting blade 25, and the cutting blade 25 is placed on the pads 45 on both sides of mounting plate 2 44. Then, motor 2 41 drives shaft 1 42 to rotate, so that the cutting blade 25 and its internal mold are below sprayer 414. Sprayer 414 sprays release agent. Motor 2 41 continues to drive shaft 1 42 to rotate, so that mounting plate 2 44 is directly below demolding pressure plate 411. Telescopic cylinder 47 drives lifting guide column 48 to descend, and demolding pressure plate 411 pushes the mold down to complete demolding. Motor 2 41 drives shaft 1 42 to rotate again, so that the cutting blade 25 returns to directly below mounting plate 1 22. Motor 1 26 drives clamp 24 to clamp the cutting blade 25 again to facilitate cutting the next mold to be cut. The user can then remove the demolded mold.

[0039] After the mold completes the trimming and is demolded, the telescopic cylinder 34 in the waste material handling component 3 drives the pressure plate 310 to rise, and the telescopic cylinder 32 drives one side of the platform 39 to lift, so that the waste material edge slides down and automatically slides out of the equipment through the discharge plate 31. After the waste material edge slides down, the telescopic rod of the telescopic cylinder 32 shortens, so that the platform 39 returns to the horizontal state, so as to carry out the trimming operation of the next mold to be trimmed.
