Description

Technical Field

[0001] This invention relates to the field of pipeline cleaning technology, specifically to a cleaning device for cooling pipelines of plastic product molds. Background Technology

[0002] In the plastic product manufacturing process, the cooling efficiency of the mold directly determines the molding cycle and quality stability of the product. As the core of heat exchange in the mold, the cooling pipes are prone to scale buildup, microbial slime growth, and oil contamination on their inner walls over long-term use. These deposits significantly reduce the thermal conductivity of the pipes, leading to uneven mold cooling, which in turn causes defects such as warping and shrinkage marks in the product and prolongs the injection molding cycle. Therefore, regular and thorough cleaning of the cooling pipes is a crucial step in maintaining efficient production and ensuring product quality.

[0003] Currently, there are various existing technologies for cleaning mold cooling pipes. For mechanical cleaning, a common method involves a rigid flexible shaft driven by a motor, with a wire brush or grinding head installed at the end of the shaft. The operator inserts the brush head into the pipe and removes dirt through rotational friction. During the cleaning process, to accommodate pipes of varying depths, a common practice is for the operator to hold the entire device and move it forward and backward, or to manually adjust the extension length of the flexible shaft sleeve by turning the adjustment mechanism to roughly position the brush head.

[0004] However, the aforementioned existing technology has problems: when cleaning pipes at different depths, adjusting the working length of the brush head is cumbersome and the positioning efficiency is low, making it impossible to achieve fast, accurate, progressive positioning and reliable locking. This results in excessively long preparation time in maintenance scenarios that require frequent switching of cleaning positions, seriously affecting the overall maintenance efficiency and also causing inconvenience to the operation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a cleaning device for cooling pipes of plastic product molds, which solves the problem that existing mold cooling pipe cleaning technologies suffer from cumbersome brush head length adjustment operations and low positioning efficiency, severely restricting the overall efficiency of maintenance operations.

[0009] Preferably, the disassembly and assembly assembly includes a connecting block, which is fixedly connected to both sides of the plug rod. A rotating shaft is rotatably connected inside the connecting block, and a clamping plate is fixedly connected to the lower side of the rotating shaft. The clamping plate is slidably connected inside the fixing groove. A third spring is fixedly connected to both sides inside the connecting block, and the third spring is fixedly connected to the adjacent side of the clamping plate.

[0010] Preferably, a water collection tank is fixedly connected to the lower side of the fixed shell, and evenly distributed nozzles are fixedly connected to the lower side of the water collection tank. A fixed pipe is fixedly connected to the right side of the water collection tank, and a cleaning component is fixedly connected to the top of the fixed pipe. The cleaning component is used to facilitate the connection of the hose and to facilitate the flushing of the pipe.

[0011] Preferably, the cleaning component includes a retaining ring, which is fixedly connected to the top end of a retaining tube. A threaded groove is provided on the upper side of the retaining ring, and a threaded tube is threadedly connected inside the threaded groove. A flexible tube is fixedly connected to the top end of the threaded tube.

[0012] Preferably, a fixing sleeve is fixedly connected to the lower inner side of the fixing shell, and the connecting shaft is slidably connected inside the fixing sleeve.

[0014] Preferably, the connecting block is slidably connected inside the through groove and the connecting groove.

[0015] Preferably, the fixed cylinder has limit grooves on both sides, and the limit block is slidably connected inside the limit groove.

[0016] Working Principle: When using this device, operators often need to adjust the position of the cleaning brush head according to the depth or internal structure of the cooling pipes during actual mold maintenance. During operation, first hold the handle, align the device with the mold's cooling pipes, and press the control button to start the drive motor. The drive motor drives the cleaning brush head to rotate via the connecting shaft, cleaning the inner wall of the pipes. When adjusting the extension length of the cleaning brush head, the operator manually pulls the brush head downwards, causing the drive motor and connecting shell to move downwards as a whole. As the connecting shell moves downwards, the sliding block on its right side slides along the groove on the fixed shell, simultaneously causing the fixed rod to move downwards within the fixed cylinder, stretching the first spring. During this process, the rear side of the connecting shell... The T-shaped slot disengages from the T-shaped locking block in the limiting assembly. Once the position is adjusted, the cleaning brush head is released. At this point, the stretched first spring rebounds, pushing the connecting shell upwards. Simultaneously, the compressed second spring in the limiting assembly releases its force, pushing the T-shaped locking block forward along the telescopic rod. Under the combined action of the first and second springs, the T-shaped locking block re-engages into the corresponding T-shaped slot, providing support and limiting for the connecting shell and power components, thus fixing the position to adapt to the cleaning requirements of different pipes. When a soft brush needs to be installed, the operator aligns the insertion rod with the insertion slot at the bottom of the connecting shaft and inserts it. During insertion, the locking plates on the connecting blocks on both sides of the insertion rod... When the insertion slot is pressed, the locking plate rotates inward around the rotation axis, compressing the third spring. When the insertion rod is inserted to the designated position and the locking plate aligns with the fixing slot, the third spring pushes the locking plate outward, causing its end to engage inside the fixing slot, thus locking the insertion rod axially and enabling power transmission from the connecting shaft to the soft brush. During replacement, the operator simultaneously presses both locking plates inward to overcome the spring force of the third spring and remove them from the fixing slot, allowing the insertion rod and soft brush to be pulled out of the insertion slot without additional tools, improving replacement efficiency and ensuring the stability of the transmission connection. External water is supplied via a hose, flowing through a threaded pipe and a fixed pipe into the water collection tank. During rinsing, water is sprayed from nozzles evenly distributed on the lower side of the water tank, forming multiple jets that act on the inner wall of the mold cooling pipes being cleaned by soft brushes. The soft brushes remove scale and impurities adhering to the inner wall of the pipes, while the water jets from the nozzles flush the loosened dirt out of the pipes in time, thus achieving simultaneous brushing and rinsing. This method helps to improve the thoroughness of cleaning and prevents dirt from redepositing in the pipes. The hose is connected by the threaded tube at its end and the threaded groove on the retaining ring. This threaded connection method is designed to balance sealing reliability and ease of disassembly and assembly, making it easy to adjust the hose arrangement according to the working environment and quickly disconnect the pipeline when the equipment is transported.

[0017] This invention provides a cleaning device for cooling pipes in plastic product molds. It has the following beneficial effects: 1. This invention achieves rapid positioning and stable cleaning through an adjustable brush head mechanism. During operation, the operator holds the handle and starts the drive motor. The brush head rotates with the connecting shaft to clean. The brush head length is adjusted by pulling down the brush head, which moves the connecting shell down along the slide groove, causing the T-shaped locking block to disengage from the T-shaped slot. After being released, the first and second springs work together to push the T-shaped locking block back into the corresponding slot, automatically completing the positioning and locking. This structure allows a single person to quickly adapt to pipes of different depths during operation, improving cleaning efficiency and operational convenience.

[0018] 2. This invention enables quick assembly and disassembly of the brush head through a plug-in and snap-fit ​​structure. During installation, inserting the plug rod allows the locking plate to automatically snap into the fixing groove under the action of the third spring, completing axial locking and power transmission. During replacement, pressing the locking plates on both sides allows the brush head to be pulled out. This design requires no tools and significantly improves the efficiency of brush head replacement while ensuring transmission stability.

[0019] 3. This invention uses a nozzle to spray water onto the inner wall of the pipe being cleaned by a soft brush, achieving simultaneous brushing and rinsing, effectively improving the thoroughness of cleaning. The hose uses a threaded tube and a fixing ring for connection, ensuring both sealing and ease of disassembly and assembly, facilitating on-site pipe laying and equipment transportation.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example:

[0024] Please see the appendix Figure 1 -Appendix Figure 5 This invention provides a cleaning device for cooling pipes of plastic product molds, including a fixed shell 1. A control key 2 is fixedly connected to the front side of the fixed shell 1, and a handle 3 is fixedly connected to the left side of the fixed shell 1. A fixed cylinder 4 is fixedly connected to the upper inside of the fixed shell 1, and a fixed rod 5 is slidably connected inside the fixed cylinder 4. A connecting shell 9 is fixedly connected to the bottom end of the fixed rod 5, and limit blocks 6 are fixedly connected to both sides of the fixed rod 5. A first spring 8 is sleeved on the outside of the fixed cylinder 4 and the fixed rod 5. The top end of the first spring 8 is fixedly connected to the upper inside of the fixed shell 1, and the bottom end of the first spring 8 is fixedly connected to the upper side of the connecting shell 9. A drive motor 10 is fixedly connected inside the connecting shell 9, and the output end of the drive motor 10 is... A connecting shaft 11 is fixedly connected. A sliding block 13 is fixedly connected to the right side of the connecting shell 9. A sliding groove 14 is opened on the right side of the fixed shell 1. The sliding block 13 is slidably connected inside the sliding groove 14. A uniformly distributed T-shaped slot 15 is opened on the rear side of the connecting shell 9. A limiting component is fixedly connected to the rear side of the fixed shell 1. The limiting component is used to support and limit the connecting shell 9. The limiting component includes a connecting cylinder 16, which is fixedly connected to the rear side of the fixed shell 1. A telescopic rod 17 is fixedly connected to the rear side of the connecting cylinder 16. A second spring 18 is sleeved on the outside of the telescopic rod 17. A T-shaped block 19 is fixedly connected to the output end of the telescopic rod 17. The T-shaped block 19 is slidably connected inside the T-shaped slot 15.

[0025] When using this device, operators often need to adjust the position of the cleaning brush head according to the depth or internal structure of the cooling pipe when maintaining the mold. During operation, first hold handle 3, align the device with the mold cooling pipe, press control key 2 to start drive motor 10. Drive motor 10 drives the cleaning brush head to rotate through connecting shaft 11 to clean the inner wall of the pipe. When it is necessary to adjust the extension length of the cleaning brush head, the operator manually pulls the brush head down, causing drive motor 10 and connecting shell 9 to move down as a whole. When connecting shell 9 moves down, its right sliding block 13 slides along the sliding groove 14 on the fixed shell 1, and at the same time, it drives the fixed rod 5 to move down in the fixed cylinder 4, causing the first spring 8 to be stretched. During this process, the T-shaped slot 15 on the rear side of connecting shell 9 and the T-shaped slot in the limiting assembly... The locking block 19 disengages; once the position is adjusted to the correct position, the cleaning brush head is released. At this time, the stretched first spring 8 rebounds, pushing the connecting shell 9 upward as a whole. Simultaneously, the second spring 18, which is in a compressed state within the limiting component, releases its elastic force, pushing the T-shaped locking block 19 forward along the telescopic rod 17. Under the coordinated action of the first spring 8 and the second spring 18, the T-shaped locking block 19 re-engages into the corresponding T-shaped slot 15, thereby supporting and limiting the connecting shell 9 and the power component, and completing the position fixation to adapt to the cleaning requirements of different pipes.

[0026] Please see the appendix Figure 6 Appendix Figure 7 Appendix Figure 8 The bottom end of the connecting shaft 11 is provided with a plug-in groove 20. Both sides of the plug-in groove 20 are provided with through grooves 21. A connecting groove 22 is provided on the side of the through groove 21 that is far away from each other. A fixing groove 23 is provided on the side of the connecting groove 22 that is far away from each other. A plug-in rod 24 is slidably connected inside the plug-in groove 20. A soft brush 25 is fixedly connected to the outside of the plug-in rod 24. Both sides of the plug-in rod 24 are fixedly connected with a disassembly and assembly assembly. The disassembly and assembly assembly is used to facilitate the disassembly and replacement of the soft brush 25. The disassembly and assembly assembly includes a connecting block 26. The connecting block 26 is fixedly connected to both sides of the plug-in rod 24. A rotating shaft 27 is rotatably connected inside the connecting block 26. A clamping plate 28 is fixedly connected to the lower side of the rotating shaft 27. The clamping plate 28 is slidably connected inside the fixing groove 23. A third spring 29 is fixedly connected to both sides of the inside of the connecting block 26. The third spring 29 is fixedly connected to the side of the clamping plate 28 that is close to each other.

[0027] When using this device, when it is necessary to install the soft brush 25, the operator aligns the plug rod 24 with the plug slot 20 at the bottom of the connecting shaft 11 and inserts it. During the insertion process, the retaining plates 28 on the connecting blocks 26 on both sides of the plug rod 24 contact and are pressed against the opening of the plug slot 20, causing the retaining plates 28 to rotate inward around the rotating shaft 27 and compress the third spring 29. When the plug rod 24 is inserted to the designated position and the retaining plates 28 are aligned with the fixing slot 23, the third spring 29 pushes the retaining plates 28 to rotate outward, so that its end is locked into the fixing slot 23, thus completing the axial locking of the plug rod 24, thereby realizing the power transmission from the connecting shaft 11 to the soft brush 25. When replacing, the operator simultaneously presses the retaining plates 28 on both sides inward to overcome the elastic force of the third spring 29 and withdraw them from the fixing slot 23, so that the plug rod 24 and the soft brush 25 can be pulled out from the plug slot 20 without the need for additional tools, which helps to improve the replacement efficiency and ensure the stability of the transmission connection.

[0028] Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 9 A water collection tank 30 is fixedly connected to the lower side of the fixed housing 1. Evenly distributed nozzles 31 are fixedly connected to the lower side of the water collection tank 30. A fixed pipe 32 is fixedly connected to the right side of the water collection tank 30. A cleaning component is fixedly connected to the top end of the fixed pipe 32. The cleaning component is used to facilitate the connection of the hose 36 and to facilitate the flushing of the pipe. The cleaning component includes a fixing ring 33, which is fixedly connected to the top end of the fixed pipe 32. A threaded groove 34 is opened on the upper side of the fixing ring 33. A threaded pipe 35 is threadedly connected inside the threaded groove 34. A hose 36 is fixedly connected to the top end of the threaded pipe 35.

[0029] When using this device, an external water source is connected through a hose 36. The water flows through a threaded pipe 35 and a fixed pipe 32 into a water collection tank 30. When rinsing is performed, the water is sprayed from nozzles 31 evenly distributed on the lower side of the water collection tank 30, forming multiple jets that act on the inner wall of the mold cooling pipe being cleaned by the soft brush 25. The soft brush 25 is responsible for brushing away scale and impurities adhering to the inner wall of the pipe, while the water jets from the nozzles 31 can flush the loosened dirt out of the pipe in time, thus achieving simultaneous brushing and rinsing. This method helps to improve the thoroughness of cleaning and prevents dirt from redepositing in the pipe. The hose 36 is connected by the threaded pipe 35 at its end and the threaded groove 34 on the fixed ring 33. This threaded connection method is designed to balance sealing reliability and ease of disassembly and assembly, making it easy to adjust the hose 36 arrangement according to the working environment and quickly separate the pipeline when the equipment is transported.

[0030] Please see the appendix Figure 3 -Appendix Figure 7A fixed sleeve 12 is fixedly connected to the lower inner side of the fixed shell 1, and the connecting shaft 11 is slidably connected inside the fixed sleeve 12; one end of the second spring 18 is fixedly connected to the inside of the connecting cylinder 16, and the other end of the second spring 18 is fixedly connected to the rear side of the T-shaped locking block 19; the connecting block 26 is slidably connected inside the through groove 21 and the connecting groove 22; limit grooves 7 are opened on both sides of the fixed cylinder 4, and the limit block 6 is slidably connected inside the limit groove 7.

[0031] A fixed sleeve 12 is fixedly connected to the lower inner side of the fixed housing 1. The connecting shaft 11 passes through and is slidably connected inside the fixed sleeve 12. This structure provides an additional intermediate support point for the high-speed rotating connecting shaft 11, which can significantly reduce its radial runout during operation and ensure transmission stability. One end of the second spring 18 is fixedly connected to the rear inner side of the connecting cylinder 16, and the other end is fixedly connected to the rear side of the T-shaped locking block 19. This installation method can more effectively transmit the elastic restoring force of the second spring 18 directly to the T-shaped locking block 19, driving it to reliably engage or disengage from the T-shaped locking slot. 15; During installation and disassembly, the connecting block 26 will slide inside the through groove 21 and the connecting groove 22. The through groove 21 provides the main movement space, while the connecting groove 22 further guides the connecting block 26 and the clamping plate 28 to accurately transition to the position of the fixing groove 23. Limiting grooves 7 are opened on both sides of the fixing cylinder 4, and the limiting blocks 6 on both sides of the fixing rod 5 are precisely slidably connected inside the limiting grooves 7, which restricts the sliding stroke and rotational freedom of the fixing rod 5 in the fixing cylinder 4, ensuring that the connecting shell 9 and the drive motor 10 can only perform preset linear movements.
