Description

Technical Field

[0001] The present invention relates to the technical field of injection molds, and specifically relates to a high-precision injection mold device for optical products. Background Art

[0002] The injection molding of optical products is the product of the deep integration of precision mold technology, plastic molding process and optical design, and has become the core manufacturing technology of plastic optical components in fields such as consumer electronics, automobiles, and medical treatment. During the injection molding process of optical products, an injection mold is required. In the process of closing the mold, in order to ensure that the positions of the two molds do not deviate, it is necessary to insert the guide posts into the inside of the guide sleeves before closing the mold, so as to realize the positioning of the injection mold before closing the mold.

[0003] However, the guide shafts and guide sleeves on traditional injection molds are exposed to the external environment for a long time during use, and are extremely prone to accumulating dirt such as dust and oil. These pollutants will embed into the mating gaps of the guiding mechanism, resulting in an increase in the frictional resistance when the guide posts and guide sleeves slide, and even jamming and locking phenomena. This will not only affect the mold closing accuracy, but also exacerbate the wear of the guiding mechanism, shorten the service life of the mold, increase the frequency of shutdown maintenance, and most of the modules of existing injection molds are fixed to the mounting base by a plurality of bolts. When a module needs to be disassembled and repaired due to wear, damage, etc., the operator needs to use a specific tool to loosen the bolts one by one, and the bolts are prone to problems such as rust and slipping of the threads due to long-term use, further increasing the disassembly difficulty. This cumbersome disassembly and assembly process not only wastes a lot of time and physical strength, but also prolongs the shutdown time of the production line, seriously affecting production efficiency.

[0017] (1) The high-precision injection mold device for optical products described in the present invention can shield and protect the guide column through the protective structure and the shielding structure during use, thereby preventing dust and oil from accumulating on the outside of the guide column. The shielding structure can shield the inside of the guide sleeve, thereby preventing dust and oil from accumulating on the inside of the guide sleeve.

Detailed implementation manners

[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown in

[0033] As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the protection structure 6 includes a connecting cylinder 601 and a moving sleeve 602. One side of one of the mounting seats 1 abuts against four connecting cylinders 601. The outside of the connecting cylinder 601 is slidably connected with a moving sleeve 602. A third spring 603 abuts between the connecting cylinder 601 and the moving sleeve 602. Two guide bars 604 are fixedly connected inside the moving sleeve 602. The connecting cylinder 601 is slidably connected with the two guide bars 604. A plurality of positioning shafts 605 are fixedly connected to the mounting seat 1. Four adjacent positioning shafts 605 penetrate through the same connecting cylinder 601. A nut 606 is threadedly connected to the positioning shaft 605. The nut 606 abuts against the connecting cylinder 601. The connecting cylinder 601 is sleeved outside the adjacent guide post 9. The axes of the connecting cylinder 601 and the adjacent guide post 9 are on the same straight line. The shielding structure 7 includes a connecting seat 701 and a rotating seat 702. A connecting seat 701 is fixedly connected to the moving sleeve 602. A connecting seat 701 is also fixedly connected to the guide sleeve 10. The connecting seat 701 is rotatably connected with a rotating seat 702. A connecting sleeve 703 is fixedly connected to the rotating seat 702. A resisting sleeve 704 is slidably connected inside the connecting sleeve 703. A plurality of fourth springs 705 abut between the resisting sleeve 704 and the connecting sleeve 703. One end of the resisting sleeve 704 has a trapezoidal cross-section. The resisting sleeve 704 at one end of the guide sleeve 10 abuts against the guide sleeve 10. The resisting sleeve 704 at one end of the moving sleeve 602 abuts against the moving sleeve 602. The rotating structure 8 includes a sliding rod 801 and a guide groove 802. The sliding rod 801 is slidably connected to the connecting seat 701. The sliding rod 801 is provided with a guide groove 802. A guide shaft 803 is fixedly connected to the rotating seat 702. The guide shaft 803 extends into the guide groove 802 and is slidably connected with the sliding rod 801. A fifth spring 804 is sleeved outside the sliding rod 801. One end of the fifth spring 804 is fixedly connected to the sliding rod 801. The other end of the fifth spring 804 is fixedly connected to the connecting seat 701. The sliding rod 801 is provided with a cut surface 805. Both ends of the guide groove 802 are horizontally arranged. The middle part of the guide groove 802 has a spiral structure. One end of the sliding rod 801 extends outside the rotating seat 702. That is, during the use process, the outside of the guide post 9 can be shielded by the connecting cylinder 601 and the moving sleeve 602. Under the action of a plurality of fourth springs 705, the resisting sleeve 704 can be tightly abutted against the end of the moving sleeve 602, so as to seal the end of the moving sleeve 602, thereby realizing a comprehensive shielding of the guide post 9 and preventing dust and oil from accumulating outside the guide post 9. At the same time, the resisting sleeve 704 at one end of the guide sleeve 10 is also tightly abutted against the end of the guide sleeve 10, so as to prevent dust and oil from entering the inside of the guide sleeve 10, thereby ensuring the cleanliness inside the guide sleeve 10. Therefore, the guide post 9 and the guide sleeve 10 can keep smooth during the sliding fit process.To avoid jamming and freezing phenomena, and at the same time reduce the wear between the two, thereby improving the safety and stability of use. During the process of the two modules 2 being clamped together, the guide post 9 will move towards the guide sleeve 10, and the two opposite slide bars 801 will approach each other. When the two adjacent slide bars 801 come into contact, due to the elastic force of the third spring 603 being greater than the elastic force of the fifth spring 804, the two slide bars 801 will slide on the connecting seat 701 simultaneously. While the slide bar 801 is moving, the guide shaft 803 will move inside the guide groove 802. When the guide shaft 803 moves at the spiral position in the middle of the guide groove 802, the swivel base 702 will rotate, and the rotation of the swivel base 702 will drive the connecting sleeve 703 to move. When the guide shaft 803 moves to the horizontal position of the guide groove 802 again, the movement of the slide bar 801 will not cause the swivel base 702 to rotate. At this time, the abutting sleeve 704 at one end of the guide post 9 does not resist the end of the guide post 9, and at the same time, the abutting sleeve 704 at one end of the guide sleeve 10 does not resist the inside of the guide sleeve 10. Then, as the module 2 continues to move, the two adjacent swivel bases 702 will abut against each other, and then the module 2 will continue to move. At this time, the moving sleeve 602 will slide on the outside of the connecting cylinder 601, and the third spring 603 will contract. By providing two guide bars 604, it is possible to prevent the moving sleeve 602 and the connecting cylinder 601 from rotating, thereby preventing the positions of the two opposite slide bars 801 from shifting. Then, as the module 2 continues to move, the guide post 9 will be inserted into the inside of the guide sleeve 10. By sliding the guide post 9 inside the guide sleeve 10, the positioning before the clamping of the module 2 can be achieved. During the process of the module 2 being opened, when the third spring 603 is fully extended, the fifth spring 804 will extend to drive the slide bar 801 to reset. During the reset process of the slide bar 801, the abutting sleeve 704 will move in the opposite direction. Since the elastic force of the fifth spring 804 is much greater than the elastic force of the fourth spring 705, and the cross-section at one end of the abutting sleeve 704 is trapezoidal, when the abutting sleeve 704 abuts against the moving sleeve 602 during the reset process, multiple fifth springs 804 will contract, and the abutting sleeve 704 will slide inside the connecting sleeve 703. When the slide bar 801 is fully reset, the abutting sleeve 704 will seal the end of the moving sleeve 602. Under the action of the fifth spring 804, it is possible to make the contact between the abutting sleeve 704 and the moving sleeve 602 closer, thereby improving the sealing performance between the abutting sleeve 704 and the moving sleeve 602. Similarly, the sealing performance between the abutting sleeve 704 and the guide sleeve 10 can also be improved. By unscrewing the nut 606 from the positioning shaft 605, the disassembly of the connecting cylinder 601 can be achieved, and at the same time, the guide post 9 is exposed. After the guide post 9 is exposed, lubricating oil can be applied to the outside of the guide post 9.,

[0034] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 and Figure 9As shown in the figure, the positioning structure 3 includes a positioning block 301 and a stop block 302. Two positioning blocks 301 are fixedly connected to the mounting base 1. Two positioning grooves 303 are provided on the module 2. The positioning block 301 is slidably engaged with the adjacent positioning groove 303. A stop block 302 is fixedly connected to the mounting base 1. The bottom end of the module 2 abuts against the top end of the stop block 302. The cross section of the positioning block 301 is in a dovetail shape structure. A lifting ring 11 is fixedly connected to the top end of the module 2. The fixing structure 4 includes a clamping block 401 and a pulling groove 402. Two clamping blocks 401 are slidably connected to the mounting base 1. A pulling groove 402 is provided on one of the clamping blocks 401. The clamping block 401 is clamped with the module 2. Two connecting rods 403 are rotatably connected to the clamping block 401. Two sliders 404 are slidably connected to the mounting base 1. One end of the slider 404 is connected to one of the clamping blocks 401 through the connecting rod 403. The other end of the slider 404 is connected to the other clamping block 401 through the connecting rod 403. The connecting rod 403 is rotatably connected to the slider 404. A first spring 405 abuts between the slider 404 and the mounting base 1. The two connecting rods 403 at both ends of the slider 404 are symmetrically distributed about the middle of the slider 404. The two connecting rods 403 at both ends of the clamping block 401 are symmetrically distributed about the middle of the clamping block 401. The two clamping blocks 401 are symmetrically distributed about the middle of the slider 404. The limiting structure 5 includes a limiting block 501 and a second spring 502. A limiting block 501 is slidably connected to one of the clamping blocks 401. Two clamping slots 503 are provided on the mounting base 1. The limiting block 501 is engaged with one of the clamping slots 503. A second spring 502 abuts between the limiting block 501 and the clamping block 401. That is, by engaging the limiting block 501 with one of the clamping slots 503, it can be avoided that the clamping block 401 is accidentally touched and moves, so as to improve the stability when fixing the module 2. When it is necessary to disassemble the module 2 for maintenance, the limiting block 501 can be pressed, and the second spring 502 contracts. When the limiting block 501 is not engaged with one of the clamping slots 503, one of the clamping blocks 401 can be pulled. By providing the pulling groove 402, it can be avoided that the hand slips when pulling the clamping block 401. During the movement of one of the clamping blocks 401, two sliders 404 will be driven to move relatively through two of the connecting rods 403. The relative movement of the two sliders 404 will respectively drive the other clamping block 401 to move in the opposite direction to one of the clamping blocks 401 through the other two connecting rods 403, so that the two clamping blocks 401 move away from the module 2 at the same time. As one of the clamping blocks 401 continues to move, one end of the limiting block 501 will be aligned with the other clamping slot 503. At this time, the second spring 502 will extend to drive the limiting block 501 to engage with the other clamping slot 503. At this time, the clamping block 401 cannot be pulled continuously.Therefore, after the latch 401 is released, it can prevent the first spring 405 from elongating and causing the latch 401 to engage with the module 2 again, thus avoiding the need to constantly hold the latch 401 by hand during the disassembly process, effectively improving the operation convenience. And when the latch 401 is not engaged with the module 2, the module 2 can be lifted by the stopper 302, thus preventing the module 2 from falling under the action of gravity, effectively improving the safety during disassembly. Next, the sling can be passed through the lifting ring 11, and then the module 2 can be lifted by the lifting device. During the lifting process of the module 2, the positioning block 301 will slide inside the positioning groove 303. When the positioning block 301 and the positioning groove 303 are completely disengaged, the module 2 can be transported to the maintenance point for repair and maintenance, thus realizing the rapid disassembly of the module 2, avoiding the need for operators to loosen bolts one by one with specific tools, reducing the disassembly difficulty, saving time and physical strength, improving the operation convenience, and also avoiding the extension of the production line downtime and the serious impact on production efficiency.

[0035] When the present invention is in use, during the process of use, the outer side of the guide post 9 can be shielded through the connecting cylinder 601 and the moving sleeve 602. Under the action of a plurality of fourth springs 705, the abutting sleeve 704 can be tightly abutted against the end of the moving sleeve 602, so as to seal the end of the moving sleeve 602, thereby achieving a comprehensive shielding of the guide post 9, avoiding the accumulation of dust and oil stains outside the guide post 9. At the same time, the abutting sleeve 704 located at one end of the guide sleeve 10 is also tightly abutted against the end of the guide sleeve 10, so as to prevent dust and oil stains from entering the inside of the guide sleeve 10, thereby ensuring the cleanliness inside the guide sleeve 10. Therefore, the guide post 9 and the guide sleeve 10 can maintain smoothness during the sliding fit process, avoiding jamming and jamming phenomena, and at the same time reducing the wear between the two, thereby improving the safety and stability of use. During the process of the two modules 2 being clamped, the guide post 9 will move towards the guide sleeve 10, and the two opposite slide rods 801 will approach each other. When the two adjacent slide rods 801 come into contact, due to the elastic force of the third spring 603 being greater than the elastic force of the fifth spring 804, the two slide rods 801 will slide on the connecting seat 701 at the same time. While the slide rod 801 is moving, the guide shaft 803 will move inside the guide groove 802. When the guide shaft 803 moves at the spiral position in the middle of the guide groove 802, the rotating seat 702 will rotate, and the rotation of the rotating seat 702 will drive the connecting sleeve 703 to move. When the guide shaft 803 moves to the horizontal position of the guide groove 802 again, the movement of the slide rod 801 will not cause the rotating seat 702 to rotate. At this time, the abutting sleeve 704 at one end of the guide post 9 does not resist the end of the guide post 9, and the abutting sleeve 704 at one end of the guide sleeve 10 also does not resist the inside of the guide sleeve 10. Then, as the module 2 continues to move, the two adjacent rotating seats 702 will abut against each other, and then the module 2 will continue to move. At this time, the moving sleeve 602 will slide outside the connecting cylinder 601, and the third spring 603 will contract. By providing two guide strips 604, the rotation between the moving sleeve 602 and the connecting cylinder 601 can be avoided, thereby preventing the positions of the two opposite slide rods 801 from shifting. Then, as the module 2 continues to move, the guide post 9 will be inserted into the inside of the guide sleeve 10. By sliding the guide post 9 inside the guide sleeve 10, the positioning before the clamping of the module 2 can be realized. During the process of the module 2 being opened, when the third spring 603 is fully extended, the fifth spring 804 will extend to drive the slide rod 801 to reset. During the reset process of the slide rod 801, the abutting sleeve 704 will move in the reverse direction. Since the elastic force of the fifth spring 804 is much greater than the elastic force of the fourth spring 705, and the cross-section at one end of the abutting sleeve 704 is trapezoidal, when the abutting sleeve 704 abuts against the moving sleeve 602 during the reset process, a plurality of fifth springs 804 will contract, and the abutting sleeve 704 will slide inside the connecting sleeve 703. When the slide rod 801 is fully reset, the abutting sleeve 704 will seal the end of the moving sleeve 602.Under the action of the fifth spring 804, the abutting sleeve 704 and the moving sleeve 602 can be abutted more closely, thereby improving the sealing performance between the abutting sleeve 704 and the moving sleeve 602. Similarly, the sealing performance between the abutting sleeve 704 and the guide sleeve 10 can also be improved. By unscrewing the nut 606 from the positioning shaft 605, the disassembly of the connecting cylinder 601 can be realized, and at the same time, the guide post 9 is exposed. After the guide post 9 is exposed, lubricating oil can be applied to the outside of the guide post 9;

[0036] The engagement between the limit block 501 and one of the card slots 503 can prevent accidental contact with the card block 401 and cause the card block 401 to move, thereby improving the stability when the module 2 is fixed. When it is necessary to disassemble the module 2 for maintenance, the limit block 501 can be pressed, and the second spring 502 contracts. When the limit block 501 is not engaged with one of the card slots 503, one of the card blocks 401 can be pulled. By setting the pull groove 402, the situation of hand slipping can be avoided when pulling the card block 401. During the movement of one of the card blocks 401, two sliders 404 will move relatively through two of the connecting rods 403. The relative movement of the two sliders 404 will respectively drive the other card block 401 to move in the opposite direction to one of the card blocks 401 through the other two connecting rods 403, so that the two card blocks 401 move away from the module 2 at the same time. As one of the card blocks 401 continues to move, one end of the limit block 501 will face the other card slot 503. At this time, the second spring 502 will extend to drive the limit block 501 to engage with the other card slot 503. At this time, the card block 401 cannot be pulled continuously, so that after the card block 401 is released, the first spring 405 will not extend to cause the card block 401 to engage with the module 2 again, thus avoiding the need to always hold the card block 401 by hand during the disassembly process, effectively improving the operation convenience. And after the card block 401 is not engaged with the module 2, the module 2 can be lifted by the block 302, thereby preventing the module 2 from falling under the action of gravity, effectively improving the safety during disassembly. Next, the sling can be passed through the hanging ring 11, and then the module 2 can be lifted by the lifting device. During the lifting process of the module 2, the positioning block 301 will slide inside the positioning groove 303. When the positioning block 301 and the positioning groove 303 are completely separated, the module 2 can be transported to the maintenance point for maintenance, thus realizing the rapid disassembly of the module 2, avoiding the need for operators to loosen bolts one by one with specific tools, reducing the disassembly difficulty, saving time and physical strength, improving the operation convenience, and also avoiding the extension of the production line downtime and the serious impact on production efficiency.
