Description

Technical Field

[0001] This utility model belongs to the field of injection molding nozzle cleaning technology, specifically an injection molding nozzle cleaning device for injection molding machines. Background Technology

[0002] After the injection molding machine finishes processing, due to the inherent characteristics of molten plastic, it often adheres to the inside of the injection port. The residual molten plastic can cause defects such as air marks or stringing on the surface of plastic products produced later. Therefore, workers will use an injection port cleaning device to clean the injection port.

[0003] Chinese Patent Publication No. CN217318982U discloses an injection nozzle cleaning device for an injection molding machine, comprising a fixed box. A rotating tube is rotatably connected to the left end of the fixed box, and the right end of the rotating tube extends into the interior of the fixed box. A toothed ring is fitted onto the right side of the tail of the rotating tube. A first motor is installed on the bottom inside the fixed box, and a gear is fixedly connected to the output end of the first motor, meshing with the toothed ring. A sealing plate is fixedly connected to the right end of the rotating tube, and a second motor is installed at the right end of the sealing plate. The output end of the second motor extends into the interior of the rotating tube and is fixedly connected to a screw. An adjusting sleeve is threaded onto the outside of the screw, and adjusting plates are rotatably connected to the outer wall of the adjusting sleeve. Slots are provided on the rotating tube at positions corresponding to the four adjusting plates, and each adjusting plate is located inside the slot. This device prevents waste material from being pushed into the injection molding machine, ensuring the cleanliness of the machine's interior and facilitating subsequent injection molding, thus improving its practicality.

[0004] The aforementioned injection nozzle cleaning device can clean the residual material adhering to the inside of the injection nozzle during operation, but it requires pulling the entire device to complete the cleaning work. However, it is difficult to move horizontally during movement, which can easily cause the cleaning components to detach from the inside of the injection tube, ultimately affecting the overall cleaning effect. Therefore, an injection nozzle cleaning device for injection molding machines is proposed to address the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Specific implementation examples are given below.

[0028] Please see Figures 1-7This utility model provides an injection nozzle cleaning device for an injection molding machine, including a main body shell 1; a storage groove 11 is provided inside the main body shell 1; multiple sets of spring support rods 12 are fixedly connected to the side wall of the storage groove 11; a connecting ring 13 is fixedly connected to the end of the multiple sets of spring support rods 12 away from the main body shell 1; a fixing ring 14 is slidably connected to the top and bottom of the connecting ring 13; a first threaded post 15 is threadedly connected to the top and bottom of the connecting ring 13; the first threaded post 15 and the fixing ring 14 are rotatably connected; a connecting rod 16 is fixedly connected to the side wall of the storage groove 11; an extrusion cone 17 is slidably connected to the inner side of the connecting rod 16; a fixing ring 18 is fixedly connected to the end of the connecting rod 16 away from the main body shell 1. The fixed ring 18 has multiple sets of sliding grooves 19 on its sidewall; an extrusion block 110 is slidably connected to the inner side of the sliding groove 19; a cleaning scraper 111 is fixedly connected to the end of the extrusion block 110 away from the extrusion cone 17; the cleaning scraper 111 is located on the side of the fixed ring 18 away from the extrusion cone 17; a sealing soft plate 112 is connected between the multiple sets of cleaning scrapers 111; a fixed post 113 is fixedly connected to the top of the storage slot 11; a threaded rotating post 114 is rotatably connected to the bottom of the fixed post 113; a second threaded post 115 is slidably connected to the inner side of the fixed post 113; the second threaded post 115 and the threaded rotating post 114 are threadedly connected; a toothed post 116 is rotatably connected to the sidewall of the main body shell 1; the toothed post 116... 6. Engages with the threaded rotating column 114; during operation, after the connecting ring 13 is fitted onto the injection port, the pair of first threaded columns 15 are rotated to bring the pair of fixed retaining rings 14 closer together and clamp them on the outside of the injection port; at this time, the connecting rod 16 enters the inside of the injection port, and by rotating the toothed column 116, the fixed column 113, the threaded rotating column 114 and the second threaded column 115 engage with each other, causing the second threaded column 115 to move downward and squeeze the end of the extrusion cone 17 near the second threaded column 115. The extrusion cone 17 moves towards the fixed ring 18, and the extrusion cone 17 can squeeze multiple sets of extrusion blocks 110. Through the interaction of the sliding groove 19, the extrusion blocks 110, the cleaning scraper 111 and the sealing soft plate 112, it can make... Multiple sets of cleaning scrapers 111 move outward, eventually bringing the outer wall of the cleaning scraper 111 into contact with the inner wall of the injection port. At this point, the operator can directly move the main body shell 1 horizontally to drive the cleaning scraper 111 to clean the residue adhering to the inner wall of the injection port. The horizontal movement of the main body shell 1 reduces the difficulty of horizontal movement during the overall device, which could easily cause the cleaning components to detach from the inner side of the injection tube, ultimately affecting the overall cleaning effect. Furthermore, the operator can adjust the distance the cleaning scraper 111 moves outward by rotating the toothed column 116, allowing the overall device to adapt to the cleaning work of injection ports of different sizes, thereby improving the adaptability of the overall device to different injection molding equipment.

[0029] Furthermore, such as Figure 6As shown, a fixed base 2 is fixedly connected to the bottom of the connecting rod 16; multiple sets of fixed bases 2 are fixedly connected to the bottom of the connecting rod 16; a return gear 21 is rotatably connected to the inner side of each fixed base 2; return springs 22 are fixedly connected to both side walls of the return gear 21; the return springs 22 are interconnected with the side walls of the fixed base 2; a toothed groove 23 is opened at the bottom of the extrusion cone 17; multiple sets of toothed grooves 23 are provided at the bottom of the extrusion cone 17; the return springs 22 mesh with the toothed grooves 23; during operation, when the operator rotates the toothed column 116, the second threaded column 115 is squeezed against the toothed column. When the pressing cone 17 is pressed and moves, the reset gear 21, the reset spring 22 and the tooth groove 23 cooperate with each other, and the reset spring 22 deforms accordingly. After the injection port is cleaned, the operator operates the tooth column 116 to reset, and the second threaded column 115 no longer presses the pressing cone 17. The deformed reset gear 21 can be reset and drive the reset gear 21 and the tooth groove 23 to reset, so that the pressing cone 17 is reset together, thereby allowing the cleaning scraper 111 to be stored, reducing the occurrence of the cleaning scraper 111 colliding with the outside when it is not in working state.

[0030] Furthermore, such as Figure 1 and Figure 2 As shown, a limiting slide rail 3 is fixedly connected to one end of the main body shell 1 near the connecting rod 16; multiple sets of limiting slide rails 3 are fixedly connected to the side wall of the main body shell 1; a closed sleeve post 31 is sleeved on the outside of the connecting rod 16; a sliding column 32 is slidably connected to the inside of the limiting slide rail 3; the sliding column 32 and the inner side wall of the closed sleeve post 31 are connected to each other; during operation, when the main body shell 1 is not in operation, the limiting slide rail 3 and the sliding column 32 cooperate with each other to make the closed sleeve post 31 sleeved on the outside of the connecting rod 16. The closed sleeve post 31 can block external impurities, thereby reducing the occurrence of external impurities directly adhering to the outside of the fixing ring 18 and the connecting rod 16, and improving the cleanliness of the cleaning component.

[0031] Furthermore, such as Figure 5 and Figure 6 As shown, the extrusion cone 17 has a rotating groove 4 at the end away from the fixed ring 18; a fitting wheel 41 is rotatably connected to the inner side of the rotating groove 4; the fitting wheel 41 is located on the same vertical plane as the second threaded post 115; during operation, before the second threaded post 115 extrudes the extrusion cone 17, it first fits against the outer wall of the fitting wheel 41, and the fitting wheel 41 rotates along with the second threaded post 115 as it moves. The fitting wheel 41 can effectively reduce the friction between the contact surface of the second threaded post 115 and the extrusion cone 17, thereby improving the stability and service life of the extrusion cone 17 during long-term operation.

[0032] Furthermore, such as Figure 7As shown, a limiting groove 51 is provided through the side wall of the extrusion block 110; a limiting rod 5 is slidably connected to the inner side of the limiting groove 51; the limiting rod 5 is connected to the side wall of the slide groove 19; during operation, as the extrusion block 110 moves inside the slide groove 19, the limiting rod 5 and the limiting groove 51 cooperate with each other to support the middle of the extrusion block 110, thereby improving the stability of the extrusion block 110 during long-term operation and reducing the load at the connection between the extrusion block 110 and the slide groove 19.

[0033] Furthermore, such as Figure 1 As shown, an observation window 6 is provided on the top of the main body shell 1; the observation window 6 is located on the side of the fixed column 113 near the connecting rod 16; during operation, the staff can observe the device inside the storage slot 11 through the inside of the observation window 6, thereby improving the speed of timely response when problems occur in the device inside the storage slot 11.

[0034] Furthermore, such as Figure 4 As shown, a pair of flexible plates 7 are provided on the inner sidewall of the connecting ring 13; the flexible plates 7 are connected to the inner sidewall of the fixing ring 14; during operation, the flexible plates 7 are made of elastic material; when the fixing ring 14 presses and fixes the outer sidewall of the injection port, the flexible plates 7 are in contact with the outer sidewall of the injection port, and because the flexible plates 7 are made of elastic material, the friction between the fixing ring 14 and the outer sidewall of the injection port is reduced for a long time, thus reducing the occurrence of severe wear.

[0035] Working principle: During operation, after the connecting ring 13 is fitted onto the injection port, rotating a pair of first threaded posts 15 causes a pair of fixed retaining rings 14 to move closer together and clamp onto the outside of the injection port. At this time, the connecting rod 16 enters the inside of the injection port. Rotating the toothed post 116 causes the fixed post 113, the threaded post 114, and the second threaded post 115 to cooperate with each other, causing the second threaded post 115 to move downward and squeeze the end of the extrusion cone 17 near the second threaded post 115. The extrusion cone 17 moves towards the fixed ring 18. The extrusion cone 17 can squeeze multiple sets of extrusion blocks 110. Through the cooperation of the sliding groove 19, the extrusion blocks 110, the cleaning scraper 111, and the sealing soft plate 112, multiple sets of extrusion blocks 110 can be squeezed. The cleaning scraper 111 moves outward until its outer wall is in contact with the inner wall of the injection port. At this point, the operator can directly move the main body shell 1 horizontally to drive the cleaning scraper 111 to clean the residue adhering to the inner wall of the injection port. The horizontal movement of the main body shell 1 reduces the difficulty of horizontal movement, which could lead to the cleaning components detaching from the inside of the injection tube, ultimately affecting the overall cleaning effect. Furthermore, the operator can adjust the outward movement distance of the cleaning scraper 111 by rotating the toothed column 116, allowing the device to adapt to cleaning injection ports of different sizes, thus improving its adaptability to different injection molding equipment. The adaptability; during operation, when the operator rotates the gear column 116 to cause the second threaded column 115 to press against the extrusion cone 17, causing the extrusion cone 17 to move, the reset gear 21, reset spring 22, and tooth groove 23 cooperate with each other, and the reset spring 22 deforms accordingly; after the injection port is cleaned, the operator operates the gear column 116 to reset, the second threaded column 115 no longer presses against the extrusion cone 17, the deformed reset gear 21 can reset and drive the reset gear 21 and tooth groove 23 to reset, so that the extrusion cone 17 is reset together, thereby allowing the cleaning scraper 111 to be stored, reducing the occurrence of the cleaning scraper 111 colliding with the outside when it is not in the working state; during operation, when the main body is outside When the shell 1 is not in operation, the limiting slide rail 3 and the slide column 32 cooperate with each other to make the closed sleeve column 31 fit on the outside of the connecting rod 16. The closed sleeve column 31 can block external impurities, thereby reducing the occurrence of external impurities directly adhering to the outside of the fixing ring 18 and the connecting rod 16, and improving the cleanliness of the cleaning component. When in operation, before the second threaded column 115 squeezes the extrusion cone 17, it first fits against the outer wall of the fitting wheel 41. As the second threaded column 115 moves, the fitting wheel 41 rotates with it. The fitting wheel 41 can effectively reduce the friction between the contact surface of the second threaded column 115 and the extrusion cone 17, and improve the stability and service life of the extrusion cone 17 during long-term operation.During operation, as the extrusion block 110 moves within the slide groove 19, the limiting rod 5 and the limiting groove 51 cooperate to support the middle of the extrusion block 110, thereby improving the stability of the extrusion block 110 during long-term operation and reducing the load at the connection between the extrusion block 110 and the slide groove 19. During operation, the operator can observe the internal device of the storage slot 11 through the observation window 6, thus improving the speed of response to problems with the internal device of the storage slot 11. During operation, the bonding flexible plate 7 is made of elastic material. When the fixing ring 14 extrudes and fixes the outer wall of the injection port, the bonding flexible plate 7 also adheres to the outer wall of the injection port. Because the bonding flexible plate 7 itself is made of elastic material, it reduces the risk of severe wear caused by prolonged friction between the fixing ring 14 and the outer wall of the injection port.
