Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mold laser processing, in particular to a surface treatment device of an injection mold. BACKGROUND

[0002] In the injection molding industry, the surface state of the injection mold directly determines the product quality, mold closing accuracy and mold life. In long-term work of the mold, burrs are easily generated in many parts such as the cavity, the side edge and the parting surface, and pollutants such as carbon deposition and oxidation layer are formed due to contact with high-temperature plastics, release agents and the like. If the above defects are not treated in time, product defects, accelerated mold wear, increased maintenance costs and downtime losses are easily caused, so regular treatment of the mold surface is a key link.

[0003] Compared with traditional methods such as chemical treatment and mechanical grinding, laser surface treatment technology has become the mainstream direction for mold deburring and pollutant stripping due to its non-contact, high precision, no pollution and low damage advantages. However, in practical application, there is a contradiction between multi-surface treatment demand and single treatment direction. Burrs or pollutants are generated in many areas of the mold, and the quality of side edge treatment affects the assembly accuracy. However, existing laser equipment is mostly fixed laser heads or single-axis mechanisms, which can only be processed in one direction, and manual clamping and turning over are required multiple times, which is time-consuming and labor-intensive and is prone to positioning errors. In addition, there is a blind area in the side edge treatment caused by clamping and shielding. The mold needs to be fixed by a clamp during treatment, and the traditional clamp face contact or large-area positioning will block the side edge, so the laser cannot reach directly. Even with simple multi-axis equipment, the problem of insufficient treatment coverage may occur due to clamp interference. SUMMARY

[0015] The surface treatment device of the injection mold has the following advantages:

[0016] 1. The device realizes automatic processing of multiple surfaces, completely replaces manual multiple clamping and surface turning, and improves processing efficiency and positioning accuracy. The device constructs an automatic surface turning and clamping system through the linkage of the turning mechanism and the butt joint unit: the driving motor drives gear one to rotate, gear one drives driving ring to rotate through the butt joint teeth, driving ring moves the mounting cylinder and the mounting block of the butt joint unit to realize preliminary clamping of the mold on one hand, and on the other hand, the driving teeth mesh with the gear two of the butt joint unit to drive the connecting rod and the push block to move, so that the clamping plate two and the clamping plate one form a full-range clamping in an up-down direction, and finally the mold is turned over through the rotation of the connecting rod. The whole process does not need manual intervention to adjust the clamping direction of the mold, which not only avoids the time-consuming and laborious problem of manual multiple clamping and surface turning, but also eliminates the positioning error caused by manual operation, ensures the consistency of the position of each surface of the mold, and greatly improves the overall processing efficiency and accuracy.

[0017] 2. The device optimizes the design of the clamping structure, eliminates the side treatment blind area, and improves the treatment coverage and assembly accuracy. The traditional equipment is easy to block the side of the mold due to the face contact or large-area positioning of the clamp, resulting in a laser treatment blind area. The device adopts a combination structure of side clamping and bottom lifting of the docking unit. The clamping plate is clamped into the bottom of the mold to realize lifting, and the mold is clamped from both sides through the installation block. The top block driven by the driving ring drives the docking unit to act accurately, avoiding the large-area shielding problem of the traditional clamp. At the same time, the two groups of oppositely arranged docking units work alternately to comprehensively cover the areas of the mold that are not clamped, ensuring that the laser can reach the key parts such as the side of the mold, effectively solving the problem of insufficient treatment coverage caused by clamping shielding, improving the treatment quality of the side of the mold, and further ensuring the assembly accuracy of the mold.

[0018] 3. Suitable for different sizes of molds, improving the versatility and clamping stability of the device. The device realizes clamping of molds of different sizes through the cooperative design of the elastic member one, the installation cylinder and the installation block. When the mold size is larger, the installation block contacts the mold in advance, and the installation cylinder can continue to extrude the elastic member one until the top block is clamped and positioned. The buffering effect of the elastic member one can not only avoid damage to the mold caused by excessive clamping, but also ensure that molds of different sizes can be clamped stably. At the same time, the elastic member two cooperates with the connecting rod to realize the automatic reset of the push block and the second clamping plate, ensuring smooth switching of the clamping and loosening actions, and further improving the clamping ability of the device for different specifications of injection molds, expanding the application range of the device.

[0033] Please refer to Figure 1 Figure 8 A surface treatment device of an injection mold, comprising a base 1; a fixed frame 11 is arranged on one side near the top of the base 1, a sliding groove 12 is formed in the top of the fixed frame 11, a fixed seat 13 is slidably installed in the sliding groove 12, an installation rod 14 is rotatably installed at the top end of the fixed seat 13, and a laser assembly 15 is arranged at one end of the installation rod 14;

[0034] ​The fixing rod 16 is arranged at the position close to the fixing frame 11 on the top of the base 1, and the turnover mechanism 2 is arranged at the top of the fixing rod 16. The turnover mechanism 2 comprises a mounting frame 21 fixedly arranged at the top of the fixing rod 16. An installation groove 211 is formed in the outer side of the mounting frame 21. A driving ring 22 is rotatably connected in the installation groove 211. The driving ring 22 is provided with a driving tooth 222 at the top. An abutting groove 212 is formed in the mounting frame 21 at the position close to the installation groove 211. A rotating ring 223 is rotatably connected in the mounting frame 21. The inner wall of the driving ring 22 is connected with the rotating ring 223 through the abutting groove 212. An abutting hole 224 is formed in the outer wall of the rotating ring 223. An installation hole 213 is formed in the inner wall of the mounting frame 21 at the position corresponding to the abutting hole 224. An abutting unit 23 is arranged in the installation hole 213.

[0035] By adopting the above technical scheme, the fixing seat 13 is transversely slidably connected with the fixing frame 11 through the sliding groove 12, and the mounting rod 14 is rotatably connected with the fixing seat 13, so that the positioning of the laser assembly 15 can be realized, and the laser coverage of each processing surface of the mold can be ensured. The driving ring 22 forms a circumferential track with the mounting frame 21 through the installation groove 211. The power is transmitted to the abutting unit 23 through the rotating ring 223 after being transmitted through the gear one 214. The pushing assembly 19 drives the top plate 18 to ascend and descend. The top plate 18 is connected with the mounting seat 17 through the linear guide rail to ensure stability. The top plate 18 provides temporary support for the mold during turnover. The abutting unit 23 is fixed with the mounting frame 21 through the installation hole 213. The trigger clamping plate one 2333 and the clamping plate two 234 are driven to clamp through the rotating ring 223.

[0036] The abutting tooth 221 is arranged on the circumferential outer wall of the driving ring 22. The gear one 214 is rotatably arranged in the installation groove 211 at the position close to the driving ring 22. The gear one 214 is connected with the abutting tooth 221 in meshing mode. The driving motor 215 is arranged at the position close to the gear one 214 on the bottom of the mounting frame 21. The output end of the driving motor 215 is fixedly connected with the gear one 214 through the mounting frame 21.

[0037] By adopting the above technical scheme, the driving motor 215 drives the gear one 214 to engage with the butt joint teeth 221 of the driving ring 22 to drive it to rotate in the installation groove 211, and then the butt joint groove 212 is linked to the rotating ring 223 to form a two-stage transmission, thereby ensuring the high-torque transmission efficiency. When the driving ring 22 rotates, the top block 225 extrudes the butt joint ring 231 to push the installation cylinder 231 to slide, and through the elastic member one 2334, the clamping plate one 2333 is driven to complete the lateral fixation of the mold.

[0038] The installation hole 213 is rotatably connected with the gear two 232 inside the opening of the outer wall of the installation frame 21. The gear two 232 is in meshing connection with the driving teeth 222, and the end of the gear two 232 is provided with a butt joint hole two 2321 designed in a non-circular shape. The installation cylinder 231 is provided with a butt joint hole one 2312 designed in a circular shape at the end corresponding to the butt joint hole two 2321. The installation cylinder 231 is slidably installed with the installation block 233. An end of the installation block 233 inside the installation cylinder 231 is provided with a placement hole 2331. The placement hole 2331 is slidably installed with the push block 235. The butt joint hole two 2321 is slidably connected with the connecting rod 236. One end of the connecting rod 236 extends to a position close to the push block 235 through the butt joint hole one 2312. The end of the push block 235 close to the position of the connecting rod 236 is provided with a connecting hole 2353. The end of the connecting rod 236 is provided with a butt joint shaft 2362 corresponding to the position of the connecting hole 2353. One end of the butt joint shaft 2362 extends into the connecting hole 2353 and is rotatably connected with the connecting hole 2353. The butt joint shaft 2362 is provided with a driving groove 2363 on the circumferential outer wall. The connecting hole 2353 is provided with a butt joint bolt two 2354 clamped in the driving groove 2363. The connecting rod 236 is provided with an elastic member two 2361 on the outer wall outside the butt joint hole two 2321. The installation block 233 is provided with an elastic member one 2334 at one end inside the installation cylinder 231. One end of the elastic member one 2334 is connected with the inner wall of the installation cylinder 231.

[0039] Through adoption of the above technical scheme, the connecting rod 236 penetrates the butt joint hole two 2321 of the gear two 232 and the butt joint hole one 2312 of the mounting cylinder 231 to form double guidance, the elastic member two 2361 pre-presses the connecting rod 236, and the butt joint shaft 2362 and the connecting hole 2353 of the push block 235 always maintain contact pressure. The push block 235 and the mounting block 233 form linear guidance, the driving groove 2363 of the butt joint shaft 2362 is matched, the rotational movement of the connecting rod 236 is converted into linear movement of the push block 235, and the design of the driving groove 2363 ensures that the clamping force of the clamping plate two 234 linearly increases. The elastic member one 2334 connects the mounting cylinder 231 and the mounting block 233, and the rigidity is far greater than that of the elastic member two 2361, so that the action sequence control of first pushing the mounting block 233 to complete lateral clamping and then triggering the elastic member two 2361 to compress is realized. The butt joint unit 23 is fixed through the mounting hole 213 and the mounting frame 21, and the rotating ring 223 drives the clamping action of the trigger clamping plate one 2333 and the clamping plate two 234.

[0040] The clamping plate one 2333 is arranged at the end of the mounting block 233 away from the mounting cylinder 231 and close to the bottom position, the clamping plate two 234 is slidably arranged in the mounting block 233 and close to the push block 235, the limiting groove one 2332 is arranged in the mounting block 233 and close to the clamping plate two 234, the butt joint bolt one 2341 is arranged on the outer wall of the clamping plate two 234 and corresponds to the position of the limiting groove one 2332, and one end of the butt joint bolt one 2341 extends to the inner wall of the limiting groove one 2332 and is slidably connected with the limiting groove one 2332.

[0041] Through adoption of the above technical scheme, the clamping plate one 2333 is fixed at the bottom of the mounting block 233 to form a lifting surface, the clamping force is transmitted through the mounting block 233, and the clamping plate two 234 constitutes an upper and lower clamping system. The clamping plate two 234 forms linear guidance through the butt joint bolt one 2341 and the limiting groove one 2332, the limiting slide block 2343 is embedded in the limiting groove two 2352 of the push block 235 to form auxiliary guidance, and the movement trajectory is ensured to be accurate. The butt joint surface two 2351 of the push block 235 and the butt joint surface one 2342 of the clamping plate two 234 adopt inclined surface contact to realize efficient conversion of horizontal thrust into vertical clamping force. The limiting groove two 2352 is T-shaped in cross section, cooperates with the limiting slide block 2343, ensures that the clamping plate two 234 always faces contact when lifting, and prevents the mechanism from being stuck.

[0042] The working principle and use process of the embodiment of the application are as follows:

[0043] The device realizes multi-surface blind-free laser processing of injection mold through the cooperation of the overturning mechanism 2 and multiple groups of docking units 23, solves the problems of single-direction processing of traditional equipment, manual multiple clamping and overturning, and clamping shielding, and the docking ring 2311 of the docking unit 23 is located close to the inner wall of the mounting frame 21 when the device is normally on standby; the strength of the elastic element two 2361 on the connecting rod 236 is less than that of the elastic element one 2334 on the mounting block 233, which ensures the orderly triggering of the subsequent clamping action; the laser assembly 15 is in the initial standby position, and the top plate 18 is in the raised state.

[0044] When in use, the injection mold to be processed is placed on the top of the top plate 18. The raised state of the top plate 18 in this step can avoid interference between the mold and the lower part, and facilitate stable placement. In the second step, the pushing assembly 19 is started, the pushing assembly 19 pushes the mold to move to the preset clamping position between the two groups of oppositely arranged docking units 23, realizes the preliminary positioning of the mold, lays a foundation for the subsequent accurate clamping, and improves the positioning efficiency without manual repeated adjustment of the mold position.

[0045] Then the drive motor 215 of the overturning mechanism 2 is started, the drive motor 215 drives the gear one 214 to rotate, the gear one 214 drives the entire drive ring 22 to rotate through the docking teeth 221 of the drive ring 22. During the rotation of the drive ring 22, the top block 225 on the inner side of the drive ring 22 moves synchronously to the direction of the two groups of oppositely arranged docking units 23, the top block 225 gradually extrudes the docking ring 2311 of the docking unit 23, and under the action of the extrusion force, the docking ring 2311 drives the mounting cylinder 231 to move to the direction of the mold. When the mounting cylinder 231 moves, the elastic element one 2334 in the mounting cylinder 231 synchronously pushes the mounting block 233 to move to the direction of the mold, and the mounting blocks 233 of the two groups of docking units 23 synchronously approach and clamp the mold from both sides; at the same time, the clamping plates one 2333 on the mounting blocks 233 are all clamped into the bottom of the mold, realizing the lifting support of the mold. This clamping structure adopts a combined mode of side clamping + bottom lifting, avoiding the shielding of the traditional clamp face contact or large-area positioning to the side of the mold, ensuring blind-free laser processing in the subsequent processing, and improving the side processing coverage. If the size of the mold is larger, after the mounting block 233 contacts and docks with the mold in advance, the mounting cylinder 231 continues to move and extrudes the elastic element one 2334 until the top block 225 is completely clamped between the docking ring 2311 and the mounting frame 21, at which time the drive ring 22 stops rotating, and the stable clamping of the first group of docking units 23 to the mold is completed; at the same time, the drive teeth 222 on the drive ring 22 move to the position corresponding to the gear two 232 of the docking unit 23, making preparation for the transmission for the subsequent mold overturning.

[0046] After the mold is clamped stably, the top plate 18 moves downward and is separated from the bottom of the mold to avoid interference of the top plate 18 on laser processing. The fixed seat 13 on the base 1 is started and the mounting rod 14 is started, the mounting rod 14 drives the laser assembly 15 to move, and the laser assembly 15 performs deburring and contaminant stripping processing on the upward surface of the mold.

[0047] After one side of the mold is processed, the driving motor 215 is started again to drive the gear one 214 to rotate, and the gear one 214 continues to drive the driving ring 22 to rotate; at this time, the top block 225 has been clamped between the butt joint ring 2311 and the mounting frame 21, and cannot continue to push the mounting cylinder 231 to move, but plays a role in limiting the retraction of the mounting cylinder 231, ensuring the stability of the clamped mold. During the continuous rotation of the driving ring 22, the driving teeth 222 of the driving ring 22 are engaged with the gear two 232 of the butt joint unit 23 to drive the gear two 232 to rotate. When the gear two 232 rotates, the connecting rod 236 is driven to rotate through the butt joint hole two 2321 of the gear two 232. During the rotation of the connecting rod 236, the butt joint shaft 2362 at the end of the connecting rod 236 extrudes the butt joint bolt two 2354 of the push block 235 through the driving groove 2363, so that the push block 235 moves towards the clamping plate two 234. When the push block 235 moves, the butt joint surface two 2351 of the push block 235 extrudes the butt joint surface one 2342 of the clamping plate two 234, and pushes the clamping plate two 234 to move along the limiting groove one 2332 of the mounting block 233 to the outside of the mounting block 233. At the same time, the limiting slide block 2343 of the clamping plate two 234 slides in the limiting groove two 2352 of the push block 235, ensuring the accurate direction of the movement of the clamping plate two 234; finally, the clamping plate two 234 moves to the top of the mold and is pressed tightly, cooperates with the clamping plate one 2333 at the bottom to form an upward and downward clamping of the mold, further improves the stability during the turning of the mold, and avoids the positioning error caused by the deviation of the mold during the turning. After the clamping plate two 234 is pressed tightly, the butt joint shaft 2362 cannot continue to extrude the butt joint bolt two 2354, and the butt joint bolt two 2354 is clamped into the driving groove 2363. At this time, the rotation of the connecting rod 236 drives the entire mold to rotate through the butt joint bolt two 2354, the push block 235 and the mounting block 233, and realizes the turning of the mold. Through the precise control of the driving motor 215, the mold can be turned at any angle within one week to meet different turning requirements, without manual clamping and turning, completely solving the problem of multiple clamping in the single direction processing of traditional equipment, improving the processing efficiency and avoiding positioning error. After the mold is turned to the preset angle, the driving motor 215 stops working, and the laser assembly 15 is started again to perform laser processing on the surface of the turned mold.

[0048] The above process can only complete the cleaning of four surfaces of the mold, but the remaining two surfaces of the mold are still blocked by the clamping plates. Then, the driving motor 215 is reversely rotated to drive the gear one 214, the driving ring 22 to rotate reversely, the driving teeth 222 are disengaged from the gear two 232, the push block 235 is reset under the elastic force of the elastic member two 2361, the clamping plate two 234 is disengaged from the mold after the reset of the push block 235, and the top block 225 is disengaged from between the abutting ring 2311 and the mounting frame 21. The mounting cylinder 231 drives the mounting block 233 to reset under the elastic force of the elastic member one 2334, and the first group of abutting units 23 loosen the mold. In the second step, the top plate 18 is lifted again and is abutted on the bottom of the mold to temporarily support the mold. The driving motor 215 continues to reversely rotate to drive the top block 225 of the driving ring 22 to move to the other two groups of oppositely arranged abutting units 23, and the steps of clamping, turning over and laser processing are repeated to complete the processing of the remaining part of the mold. Through the alternate work of the two groups of abutting units 23, the mold is processed in all directions, manual adjustment of the clamping direction of the mold is not needed, the processing efficiency is greatly improved, and the consistency of the processing precision of each surface is ensured.

[0049] After the four surfaces of the mold are completely processed, the abutting units 23 loosen the mold, the top plate 18 is lifted to a preset material taking position, and then the processed mold is taken out from the top plate 18. Subsequently, the driving motor 215, the pushing assembly 19 and the laser assembly 15 are reset to the initial standby state, and wait for the next processing operation.

[0050] In summary, compared with the prior art, the embodiment of the present application has the following advantages:

[0051] Advantage one: multi-surface automatic processing is realized to avoid the defects of manual clamping.

Manual clamping and turning over multiple times are not needed, the efficiency is improved, and the positioning error is avoided.

[0052] Advantage two: the side processing blind area is eliminated to improve the coverage precision. The combined structure of the abutting unit 23 side clamping and the clamping plate one 2333 bottom lifting is adopted, the abutting unit 23 is accurately driven by the top block 225 of the driving ring 22, the traditional clamp is avoided to be large-area blocked, two groups of abutting units 23 work alternately, the unclamped area of the mold is covered, the laser directly reaches the key positions such as the side edge, and the problem of insufficient processing coverage is solved.

[0053] Advantage three, suitable for different size molds, improve versatility and stability. Through the cooperation of elastic member 1 2334 and mounting cylinder 231, mounting block 233, when the mold size is larger, the mounting cylinder 231 can extrude the elastic member 1 2334 to realize stable clamping, and the elastic member 1 2334 buffers to avoid damage to the mold; elastic member 2 2361 cooperates with connecting rod 236 to realize automatic reset of push block 235 and clamp plate 2 234, guarantee smooth switching of clamping and loosening, and expand the application range of the device.

[0054] Advantage four, simplify the operation process, reduce the dependence on manual work. The push assembly 19, the turnover mechanism 2, the butt joint unit 23 and the laser assembly 15 are cooperatively linked to realize the automatic process of positioning, clamping, turning over and processing after the mold is placed; the lifting design of the top plate 18 is convenient for placing the mold and can avoid interference during processing, which greatly reduces the labor intensity and skill dependence.
