Description

Technical Field

[0001] This utility model belongs to the field of cleaning technology and relates to an automatic cleaning mechanism. Background Technology

[0002] In modern die casting production, stamping dies play a crucial role, and their condition directly affects the quality of die castings and production efficiency. However, the current process of cleaning dies faces many challenging problems.

[0003] Traditional mold cleaning mainly involves two methods: one is using a high-pressure air gun. During the die-casting and punching process, oil stains and residues inevitably adhere to the mold surface, and material often sticks to the cutting edges. Although the high-pressure air gun can blow off some loose impurities, it is often ineffective against stubborn oil stains, tightly adhered residues, and accumulations in the gaps between the cutting edges. This results in incomplete cleaning of the mold cavity, leading to surface damage on the product, severely affecting the product's appearance and internal quality, significantly increasing the scrap rate, and raising production costs.

[0004] Another method involves manually brushing the mold core surface with a hand-held steel brush. However, the internal structure of the mold is complex, and the operating space is limited. When workers use a hand-held steel brush, their hands are very likely to collide with the mold, causing abrasions, scratches, and other accidental injuries. Moreover, due to the limitations of manual operation, it is difficult to ensure that all corners of the mold cavity are thoroughly and evenly cleaned, often leaving cleaning dead spots. This significantly reduces the effectiveness of mold cleaning and fails to meet the requirements of high-precision die-casting production.

[0005] Therefore, there is an urgent need in this field for an automatic cleaning mechanism to solve the above-mentioned technical problems. Utility Model Content

[0036] Please refer to Figures 1-3One embodiment of this utility model provides an automatic cleaning mechanism to solve the problems of existing handheld steel brushes that extend into the mold core surface and pose safety hazards, and the inability to clean the mold cavity properly, making automation difficult.

[0037] Specifically, please refer to Figure 1 This is a perspective view of an automatic cleaning mechanism provided in an embodiment of the present invention. This automatic cleaning mechanism is used to clean die-casting stamping dies. The automatic cleaning mechanism includes a cleaning head 10 and a cleaning head drive component 20 for driving the cleaning head 10. The cleaning head drive component 20 drives the cleaning head 10 to move, achieving precise control of the cleaning head 10's position. It can clean dies of different sizes, and the travel path of the cleaning head 10 can be flexibly adjusted according to the required cleaning area, ensuring that the entire inner cavity of the die is effectively cleaned and avoiding cleaning dead zones. Compared to manual cleaning inside the die, the automatic cleaning mechanism of this embodiment completely avoids direct contact between the worker's hands and the sharp edges and moving parts of the die, eliminating the probability of accidental injuries such as abrasions and scratches. Operators only need to start and monitor the automatic cleaning mechanism in a safe area, without needing to enter the dangerous inner working space of the die, fundamentally ensuring the safety of personnel and providing strong support for safe production in enterprises.

[0038] Specifically, the cleaning head 10 includes a cleaning base 11, a first cleaning component 12, and a second cleaning component 13. The first cleaning component 12 is rotatably connected to the cleaning base 11, and the second cleaning component 13 is fixedly connected to the cleaning base 11. The second cleaning component 13 has a cleaning hole 131. By setting the cleaning base 11 as the basic support component of the cleaning head 10, a stable mounting platform is provided for the first cleaning component 12 and the second cleaning component 13, ensuring that they maintain a stable relative position during operation and guaranteeing the reliability of the entire cleaning head 10. The first cleaning component 12 is rotatably connected to the cleaning base 11, achieving dynamic cleaning to effectively remove oil stains, residues, and other impurities adhering to the mold. The second cleaning component 13 is fixedly connected to the cleaning seat 11, ensuring the certainty of its position. By setting a cleaning hole 131 on the second cleaning component 13, the airflow or liquid is guided to impact the mold surface in a directional manner, blowing away the dirt brushed off by the first cleaning component 12 and some impurities hidden in the gaps and grooves from the mold surface. This plays a role in assisting cleaning and enhancing the cleaning effect, making the cleaning process more thorough. It effectively solves the problem of incomplete cleaning by traditional cleaning methods, greatly reduces the risk of product damage caused by residual impurities in the mold, and improves the quality of die castings.

[0039] Furthermore, the cleaning head drive component 20 includes a cleaning head drive motor 21 and a cleaning head drive shaft 22. The cleaning head drive shaft 22 is connected to the cleaning seat 11, and the cleaning head drive component 20 drives the cleaning head 10 to move axially along the cleaning head drive shaft 22. By configuring the cleaning head drive component 20 to include a cleaning head drive motor 21 and a cleaning head drive shaft 22, the cleaning head 10 can move axially along the cleaning head drive shaft 22, achieving precise control of the cleaning head 10's position. Since the cleaning head 10 can achieve automated position movement and precise cleaning under the drive of the cleaning head drive component 20, the mold cavity can be thoroughly cleaned, meeting the stringent requirements of automated production for mold cleanliness and significantly improving cleaning efficiency.

[0040] As a further improvement of this utility model, the cleaning head 10 further includes a first cleaning component drive 14 and a first synchronous belt 15; the first cleaning component drive 14 includes a first cleaning component drive motor 141 and a first cleaning component drive shaft 142, the first cleaning component drive motor 141 being fixedly connected to the cleaning seat 11; the first cleaning component 12 includes a cleaning roller 121 and rollers 122 disposed at both ends of the cleaning roller 121, the rollers 122 being drively connected to the first cleaning component drive shaft 142 via the first synchronous belt 15. Through the transmission connection of the first synchronous belt 15, the cleaning roller 121 can obtain continuous and stable power from the first cleaning component drive motor 141, avoiding problems such as uneven cleaning force and fluctuations in cleaning effect caused by unstable power transmission. This ensures that the cleaning roller 121 closely fits the mold contour, applying just the right cleaning force to every tiny depression and protrusion, thoroughly removing stubborn oil stains and sticky residues, significantly improving the comprehensiveness and thoroughness of mold cleaning, effectively reducing the product damage and defect rate caused by incomplete mold cleaning, and ensuring the quality of die-cast parts. By setting the linkage design between the rollers 122 at both ends of the cleaning roller 121 and the first cleaning component drive shaft 142, the cleaning roller 121 can be flexibly replaced according to different scenarios. Compared with traditional fixed brush heads or simple manual tools, this adaptive rotation mechanism greatly expands the adaptability of the cleaning mechanism to the mold, eliminating the need for frequent changes of cleaning tools or manual adjustment of the operating angle, improving the efficiency of cleaning operations, and reducing manual intervention, laying a solid foundation for realizing an automated and intelligent mold cleaning process.

[0041] As a further improvement of this utility model, the second cleaning component 13 is disposed between the first cleaning component drive component 14 and the cleaning roller 121. The second cleaning component 13 is disposed between the first cleaning component drive component 14 and the cleaning roller 121, realizing the close cooperation between the second cleaning component 13 and the first cleaning component 12 in terms of spatial layout and workflow. When the cleaning roller 121 rotates at high speed under the drive of the first cleaning component drive motor 141, it performs preliminary mechanical brushing on the mold surface, loosening and peeling off oil stains and residues from the mold surface. The adjacent second cleaning component 13 can play its role immediately, realizing the perfect coordination of "brushing" and "blowing". It will not interfere with the rotation path of the cleaning roller 121, and can ensure close connection with the cleaning area of ​​the cleaning roller 121.

[0042] Specifically, please see Figure 2 The second cleaning component 13 includes a second cleaning component connecting plate 132 and an air knife 133 connected to the second cleaning component connecting plate 132. The second cleaning component connecting plate 132 is fixedly connected to the cleaning seat 11. The air knife 133 is provided with an air inlet 1333, which communicates with the cleaning hole 131. The second cleaning component connecting plate 132 is fixedly connected to the cleaning seat 11, providing a stable support platform for the air knife 133 and ensuring that the air knife 133 will not shift or shake under the impact of high-pressure airflow. The air inlet 1333 on the air knife 133 is connected to the cleaning hole 131. High-pressure gas supplied by an external air source flows in through the air inlet 1333, passes through the air passage inside the air knife 133, and is converted into a high-speed, directional airflow jet through the cleaning hole 131. This ensures that every jet of air ejected from the cleaning hole 131 can accurately impact the part of the mold that needs cleaning the most, namely the action path of the cleaning roller 121. This eliminates the waste and disorderly scattering of airflow, effectively suppresses problems such as dirt rebound and re-adhesion, ensures the stability of the mold cleaning effect, and greatly reduces the probability of product damage or defects due to poor mold cleaning.

[0043] As a further improvement of this utility model, the air knife 133 includes a first air knife 1331 and a second air knife 1332; the first air knife 1331 is provided with a first air inlet 13331 and a first cleaning hole 1311, the first air inlet 13331 communicating with the first cleaning hole 1311; the second air knife 1332 is provided with a second air inlet 13332 and a second cleaning hole 1312, the second air inlet 13332 communicating with the second cleaning hole 1312. By setting the air knife 133 to include a first air knife 1331 and a second air knife 1332, the dual air knife 133 design greatly expands the flexibility and comprehensiveness of cleaning. In the actual cleaning process, the first air knife 1331 and the second air knife 1332 can cooperate according to the characteristics and distribution of dirt in different areas of the mold surface and the complex geometry of the mold. For example, for the upper surface area of ​​the mold, the first air knife 1331 is used to impact the airflow from a specific angle to quickly blow away and peel off the oil stains; while for the lower surface area inside the mold, the second air knife 1332 is used to impact the airflow from a specific angle to quickly blow away and peel off the oil stains, so as to achieve simultaneous cleaning of the upper and lower surfaces of the mold and improve cleaning efficiency.

[0044] As a further improvement of this utility model, the extending directions of the first cleaning hole 1311 and the second cleaning hole 1312 are tangent to the outer wall of the cleaning roller 121. By setting the extending directions of the first cleaning hole 1311 and the second cleaning hole 1312 to be tangent to the outer wall of the cleaning roller 121, when the cleaning roller 121 rotates at high speed and rubs strongly against the mold surface, peeling off oil and residue from the mold surface, the tangent cleaning hole 131 allows the airflow to be precisely sprayed along the tangential direction of the cleaning roller 121, ensuring that the airflow can efficiently and quickly remove the dirt brushed off by the cleaning roller 121 from the mold surface. In actual cleaning operations, the cleaning roller 121 rotates continuously, and its outer wall continuously contacts various parts of the mold, achieving all-round brushing. The airflow blown out by the cleaning holes 131 of the first air knife 1331 and the second air knife 1332 always follows closely along the tangential line of the outer wall of the roller, as if equipping the cleaning roller 121 with two "escort airflow belts". On the one hand, for oil stains, the tangential impact of the airflow can disperse them in the smoothest way, preventing the oil stains from re-adhering due to airflow turbulence; on the other hand, for residues, the high-speed airflow in the tangential direction can give the residues an outward thrust, causing them to completely detach from the mold surface along the airflow direction. Especially when dealing with complex areas such as mold corners and gaps, this synergistic approach can ensure that the residues will not bounce back to their original position due to the airflow, maintaining the dynamic balance of the cleaning process and ensuring the stability and efficiency of the cleaning effect.

[0045] As a further improvement to this utility model, please refer to Figure 3The cleaning head drive component 20 further includes a lead screw 23 and a second synchronous belt 24. The lead screw 23 is arranged parallel to the cleaning head drive shaft 22. The output shaft of the cleaning head drive motor 21 is connected to the lead screw 23 via the second synchronous belt 24. The parallel guidance of the lead screw 23 and the cleaning head drive shaft 22, along with the precise transmission of the second synchronous belt 24, enables the cleaning head 10 to move on the mold surface with extremely high precision. When cleaning large or complex molds, the cleaning head 10 can move gradually from one end of the mold to the other, without missing any minute areas, ensuring that the entire mold cavity is cleaned evenly and thoroughly.

[0046] As a further improvement of this utility model, the cleaning head drive component 20 also includes a movable component 25, through which the lead screw 23 passes, and the end of the cleaning head drive shaft 22 is fixedly connected to the movable component 25. The lead screw 23 passing through the movable component 25 provides a precise and stable support structure for the movement of the cleaning head 10. When the lead screw 23 rotates, the movable component 25 slides flexibly along the axial direction of the lead screw 23, avoiding jamming or shaking. This high-precision sliding fit allows for more precise adjustment of the cleaning head 10's position, ensuring accurate positioning for both minor translational adjustments and long-distance movements. The fixed connection between the end of the cleaning head drive shaft 22 and the movable component 25 forms the core linkage structure driving the movement of the cleaning head 10. When the lead screw 23 rotates under the drive of the second synchronous belt 24, due to its through-connection with the movable part 25 and the fixed connection between the movable part 25 and the cleaning head drive shaft 22, the cleaning head drive shaft 22 can move synchronously with the movable part 25, thereby driving the entire cleaning head 10 to move along the predetermined axial trajectory, ensuring the stable movement of the cleaning head 10, avoiding displacement deviation of the cleaning head 10 due to loose connection during the driving process, and ensuring that the cleaning head 10 always cleans the mold precisely according to the preset path.

[0047] As a further improvement of this utility model, the cleaning head drive component 20 also includes a housing 26. A fixing member 261 is provided at one end of the housing 26 near the cleaning head 10. The cleaning head drive shaft 22 passes through the fixing member 261 and is connected to the cleaning seat 11. The end of the lead screw 23 is rotatably connected to the fixing member 261. The housing 26 serves as the external encapsulation structure of the cleaning head drive component 20, providing a physical protective barrier for the internal precision components. This isolates external dust, moisture, metal debris, and other impurities from corroding key components such as the lead screw 23, cleaning head drive shaft 22, and second synchronous belt 24, ensuring stable operation in a relatively clean environment and extending the service life of the components. After passing through the fixing member 261, the cleaning head drive shaft 22 is securely connected to the cleaning seat 11. The fixing member 261 provides positional accuracy assurance for the drive shaft in both axial and radial dimensions. In the axial direction, the forward and backward displacement deviation of the drive shaft is strictly limited to ensure that the rotational power can be stably transmitted to the cleaning seat 11 along the predetermined straight direction. In the radial direction, the sway amplitude of the drive shaft is effectively constrained to avoid irregular movement of the cleaning head 10 caused by eccentric rotation, thereby ensuring that the cleaning head 10 can move smoothly and accurately along the predetermined trajectory. The end of the lead screw 23 is rotatably connected to the fixing member 261. When the lead screw 23 rotates under power drive, it can smoothly achieve its own rotation with minimal frictional resistance through the rotational connection point with the fixing member 261, thereby driving the cleaning head drive shaft 22 to work in coordination. The three form an organic and stable linkage system, providing a solid structural foundation for the efficient and precise drive of the cleaning head 10. A tank drag chain 262 is provided on the outside of the housing 26, and the end of the tank drag chain 262 is fixedly connected to the cleaning seat 11. By installing a tank chain 262 on the outside of the housing 26, various cables, air pipes, and other pipelines connecting the cleaning head 10 to the external control system, power supply, etc., are neatly housed within it. This prevents damage to the pipelines due to tangling and pulling during movement, and also protects them from accidental damage such as mechanical collisions and abrasions caused by exposure. Moreover, the end of the tank chain 262 is fixedly connected to the cleaning seat 11, ensuring that it can move synchronously with the cleaning head 10 and adapt to the position changes of the cleaning head 10 in real time. This provides reliable logistical support for the continuous and stable operation of the cleaning head 10 and ensures the stability and continuity of the electrical and pneumatic connections of the entire cleaning system.

[0048] As a further improvement of this utility model, a positioning detector 263 is provided inside the housing 26, and a positioning detection element 251 is provided on the movable part 25. By setting the positioning detector 263, when the cleaning head 10 begins to move under the drive, causing the movable part 25 to travel axially along the lead screw 23, the positioning detection element 251 mounted on the movable part 25 also moves synchronously. Once the positioning detection element 251 enters the sensing area of ​​the positioning detector 263, the positioning detector 263 reacts quickly and accurately determines the current position of the cleaning head 10, providing a solid guarantee for the precise positioning of the cleaning head 10. In the long-term, high-intensity die-casting production environment, problems such as wear of mechanical parts and occasional program lag are difficult to completely avoid. When these abnormalities occur, potentially causing the cleaning head 10 to deviate from the normal cleaning trajectory, the positioning detection element 251 can promptly detect and issue a warning signal, avoiding serious consequences such as mold damage and incomplete cleaning caused by the misalignment of the cleaning head 10. This not only reduces equipment maintenance costs but also reduces downtime caused by malfunctions.

[0049] As a further improvement of this utility model, the cleaning roller 121 is a steel brush roller. By setting the cleaning roller 121 to a steel brush roller, the cleaning effect of the cleaning roller 121 is further enhanced. The bristles of the steel brush roller are usually made of high-strength steel wire, which has excellent wear resistance. During the cleaning process of frequent contact and friction with oil stains and residues on the mold surface, the bristles can maintain their shape for a long time, are not easy to bend or break, and ensure stable cleaning performance. For residues that are tightly adhered to the gaps and grooves of the mold, the steel brush can penetrate deep into them with its fine and tough bristles to thoroughly remove the residues, effectively improving the cleaning effect and meeting the complex and stringent cleaning requirements of die-casting molds.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
