Description

Technical Field

[0001] This invention relates to the technical field of injection molds, specifically to surface treatment equipment for molds used to customize micro fan blades. Background Technology

[0002] Post-injection mold surface treatment addresses issues such as residual plastic residue and wear marks in the mold cavity after molding. It employs processes such as electrochemical polishing, plasma cleaning, diamond grinding, and nitriding repair to quickly remove stains and optimize surface smoothness and wear resistance, reduce demolding resistance, prevent products from sticking to the mold, and repair minor damage to extend mold life, ensuring the stability of subsequent injection molding production and the surface quality of the products.

[0003] For example, Chinese patent application CN105751471A discloses a rust cleaning and protection device for injection mold surfaces, which includes a machine body. The machine body is equipped with an oiling nozzle module, a liquid storage module, a cleaning friction module, and a management module. During operation, lubricating oil is applied to the mold through the oiling nozzle module. The liquid storage module stores cleaning agents and lubricating oil, while the cleaning friction module cleans the mold. The management module processes comprehensive information. A timing module is set on the oiling nozzle module to set the time interval and time point for adding lubricating oil to the mold. A capacity sensing module is set on the liquid storage module to sense the amount of cleaning agents and lubricating oil stored within it.

[0004] However, existing mold processing devices still have some problems. For micro fans, due to their small size or the need for injection molding of support columns, the molds used for micro fan injection molding will have injection ports or holes that fit the support columns. Due to their small size, a lot of plastic waste will remain in the grooves or injection ports. The shape of the waste is not limited to strips, filaments, or blocks. After cleaning, it will adhere to the brush bristles. Therefore, during the next cleaning, the attached waste will come into contact with the inner wall of the hole, thereby causing damage to the inner surface of the mold.

[0005] Therefore, how to complete the cleaning of the mold is a problem that needs to be solved. Summary of the Invention

[0050] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0051] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0052] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0053] This invention discloses a surface treatment device for molds used to customize miniature fan blades, with reference to... Figures 1-10 ,include:

[0054] Injection molding platform 1 cools the plastic in the mold for the production of plastic fans; translation mechanism 2 is connected to injection molding platform 1; lifting platform 3 is connected to translation mechanism 2, and its position is adjusted by the movement of translation mechanism 2; impurity removal unit 4 is fixedly installed on lifting platform 3, and can clean the holes on the mold by filling with compressed gas; waste recycling unit is set on one side of impurity removal unit 4, and is used to receive plastic waste generated during injection molding and recycle it for reuse; impurity removal unit 4 includes a housing 46 fixedly connected to lifting platform 3, and the impurities are evenly distributed in the housing 46. The assembly includes a mounting base 42, a telescopic cylinder 43 fixedly connected to the mounting base 42, an adsorption component 45 disposed at the output end of the telescopic cylinder 43, a drive component 41 mounted on the housing 46, and a brushing component 44 connected to the drive component 41. When long strips or filaments of plastic waste adhere to the brush bristles, the adsorption component 45 starts to work. The moving adsorption component 45 can move along the axis of the brushing component 44 to adsorb and roll up the long strips or filaments of plastic waste on the brush bristles, so that they can be removed from the brush bristles. This avoids excessive waste on the brush bristles, which could damage the inner wall of the holes and cause damage to the mold during the brushing process.

[0055] In this device, the brushing component 44 scrapes away stubborn debris adhering to the inner wall of the holes by rotating the brush bristles, while the airflow simultaneously blows loose debris out of the holes, providing a dual cleaning function. The adsorption component 45 specifically addresses long strips and filamentous debris. This device reduces the amount of debris entangled on the brush bristles by using an axially moving adsorption and adhesive winding roller 455, preventing debris from damaging the inner wall of the holes. At the same time, the airflow can remove high-temperature residue from the mold surface, ensuring uniform mold temperature and preventing problems such as uneven cooling and deformation of the plastic fan due to excessively high local temperatures, thus improving the dimensional accuracy of the product.

[0056] The brushing assembly 44 includes a plurality of fixed brackets 444 fixedly connected to the housing 46 and evenly arranged on the housing 46, a slide rail 446 and a return spring 447 arranged on the fixed brackets 444, an adjusting rack 443 slidably arranged on the slide rail 446 and connected to the return spring 447, a gear 445 evenly arranged on the fixed brackets 444 and rotatably connected to the fixed brackets 444, a drive roller 442 arranged at one end of the adjusting rack 443, a drive disk 441 abutting against the drive roller 442, and bristles connected to the gear 445; the toothed surface of the adjusting rack 443 meshes with the gear 445; the drive disk 441 is connected to the drive assembly 41;

[0057] After the injection molding of the micro fan blades is completed, the lifting mechanism (existing technology) in the injection molding table 1 applies a thrust to the micro fan blades, allowing them to detach from the mold. Then, the translation mechanism 2 starts working, adjusting the position of the brush assembly 44. Once the brush assembly 44 is in the predetermined position, the drive assembly 41 starts working. The moving drive assembly 41 drives the push rod 414 to reciprocate along its axis. The moving push rod 414 drives the drive disk 441 to move, and the moving drive disk 441 drives the drive roller 442. The adjustment rack 443 moves, causing a relative displacement between it and the slide rail 446. The moving adjustment rack 443 drives the meshing gear 445 to rotate, which in turn drives the bristles to rotate and complete the brushing work on the inner wall of the hole. When the push rod 414 moves in the opposite direction, the return spring 447 pushes the adjustment rack 443 to move in the opposite direction. At this time, the gear 445 can also rotate in the opposite direction. Therefore, as long as the push rod 414 moves in its axial direction, it can drive the bristles to rotate, thereby completing the brushing work on the inner wall of the hole.

[0058] During this process, the drive roller 442 is always in contact with the surface of the drive disk 441, thereby ensuring the stability of the device. The drive roller 442 and the drive disk 441 are always in contact and cooperate with the preload of the return spring 447. Even if there is a slight deviation in the reciprocating motion of the push rod 414, the return spring 447 can compensate for the position of the adjusting rack 443 in real time, ensuring that the adjusting rack 443 and the gear 445 are engaged and do not disengage, and that the drive roller 442 and the drive disk 441 do not slip, ensuring that the bristles rotate continuously and stably, and avoiding incomplete cleaning due to transmission interruption.

[0059] Meanwhile, this device does not require an additional reversing mechanism. The axial reciprocating motion of the push rod 414 directly drives the bristles to rotate forward and reverse alternately through the aforementioned transmission chain. The transmission path is short and there is no energy loss. When the push rod 414 moves forward, the bristles rotate forward, and when it moves in reverse, the bristles reverse, alternately scraping the inner wall of the hole. Compared with bristles that rotate in one direction, it can more efficiently remove stubborn debris, which is especially suitable for the grooves, corners, and other areas where residue is easily left on the inner wall of the holes in micro fan molds. Furthermore, the meshing transmission between the gear 445 and the rack is highly precise, and the bristle rotation angle is proportional to the stroke of the push rod 414. This device can precisely control the bristle speed and rotation amplitude by adjusting the stroke of the push rod 414 to adapt to the brushing force requirements of different hole diameters.

[0060] The drive assembly 41 includes an air inlet pipe 411 and a second air outlet 418 connected to the housing 46, a flow divider block 412 disposed between the air inlet pipe 411 and the housing 46, a magnetic component 413 located between the flow divider block 412 and the housing 46, a first chamber formed in the housing 46, a push rod 414 located in the first chamber, and a support spring 415 for connecting the push rod 414 and the housing 46; the push rod 414 has a T-shaped structure, and one end of the push rod 414 is connected to the drive disk 441; when the drive assembly is needed... When 41 is in operation, the airflow enters the first chamber through the air inlet pipe 411 and the diverter block 412. This causes an increase in pressure at one end of the push rod 414. The increased pressure pushes the push rod 414 to move, which in turn drives the brushing assembly 44 to work and complete the brushing of the holes. After the push rod 414 moves a predetermined distance, the second air outlet 418 connects to the first chamber to complete the exhaust of the first chamber, thereby enabling the airflow to blow away the holes and reduce the amount of waste residue in the holes.

[0061] The drive assembly 41 further includes multiple connecting holes respectively opened along the axial direction of the diverter block 412. A second chamber is reserved between the housing 46 and the diverter block 412. The magnetic component 413 is located in the second chamber and divides the second chamber into two regions. The center of some connecting holes is equidistant from the center of the diverter block 412; these connecting holes form one group, and the remaining ones form another group. One group of connecting holes communicates with one region of the second chamber, and the other group communicates with the other region, and gas is delivered to the first chamber through the other group of connecting holes. By changing the gas pressure, the magnetic component 413... 13. Intermittently adsorbs with the housing 46 or the diverter block 412, changing the flow direction of the airflow and causing the push rod 414 to move; the drive assembly 41 also includes a first air outlet 416 disposed in the first chamber, a first channel 417 communicating with the first air outlet 416 and located on the housing 46, and a transfer hole disposed in the diverter block 412 and coaxially disposed with the diverter block 412; the other end of the first channel 417 is located in the diverter block 412 and communicates with the transfer hole; the first air outlet 416 and the diverter block 412 are respectively located at both ends of the push rod 414;

[0062] When pushing is required, the airflow is delivered through one of the connecting holes in the diverter block 412. Then, the moving push rod 414 moves to compress the gas in the first channel 417. When the air pressure in the first channel 417 exceeds the preset value, the airflow can impact the magnetic component 413, thereby connecting the magnetic component 413 to the housing 46. At this time, the airflow can enter the first channel 417 through another connecting hole. At this time, one end of the push rod 414 can move towards the end closer to the air inlet pipe 411, thereby enabling the push rod 414 to reciprocate, thereby driving the brushing assembly 44 to perform the brushing work.

[0063] By changing the air pressure, the magnetic component 413 intermittently attracts the housing 46 or the diverter block 412, automatically switching the airflow direction of the two sets of connecting holes, thereby driving the push rod 414 to reciprocate. There is no need for manual adjustment or configuration of electronic components such as electromagnetic reversing valves. The reversing logic is deeply coupled with the movement of the push rod 414, making it particularly suitable for long-term stable operation in the high temperature and oily environment of the injection molding workshop.

[0064] The drive assembly 41 directly utilizes the existing compressed gas in the injection molding workshop. It drives the magnetic component 413 to adsorb or separate through changes in air pressure, thereby driving the push rod 414 to reciprocate and providing power for the brushing assembly 44. It also synchronously delivers airflow to the brushing area through the connecting hole, the first channel 417, and the transfer hole to complete the flushing of the holes.

[0065] The adsorption assembly 45 includes a mounting shell 451 connected to the output end of the telescopic cylinder 43, an air intake module 452 disposed within the mounting shell 451, a rotating module 453 connected to the air intake module 452 and located within the mounting shell 451, an exhaust module 456 sleeved on the air intake module 452, a rotating shaft 454 connected to the rotating module 453, and an adhesive take-up roller 455 connected to the rotating shaft 454. The position of the adhesive take-up roller 455 is adjusted by the movement of the telescopic cylinder 43, and it is driven to rotate by the rotating module 453, thereby collecting long strips of waste adhering to the bristles. The airflow direction in the channels of the mold is changed by the exhaust module 456, thereby completing the cleaning work of the mold.

[0066] The air intake module 452 includes a first air intake pipe 4521 and a second air intake pipe 4523 disposed in the mounting housing 451, an elastic ring 4522 located between the first air intake pipe 4521 and the second air intake pipe 4523, connecting holes respectively opened on the first air intake pipe 4521 and the second air intake pipe 4523, and an air supply pipe 4524 inserted into the second air intake pipe 4523; the axis of the connecting hole is at a certain angle to the axis of the first air intake pipe 4521; when the adsorption component 45 needs to collect long strips of waste attached to the bristles, gas enters the mounting housing 451 through the first air intake pipe 4521, and since the gas entering is compressed gas, the gas can deform the elastic ring 4522, so that the gas can enter the air supply pipe 4524 through the connecting hole, thereby completing the gas delivery work;

[0067] When waste chips need to be collected, compressed gas is introduced through the first air inlet pipe 4521. The air pressure directly drives the elastic ring 4522 to deform, aligning and connecting the connecting holes of the first air inlet pipe 4521 or the second air inlet pipe 4523, and the airflow is automatically guided into the air delivery pipe 4524. When there is no gas input, the elastic ring 4522 returns to its original position due to its elasticity, and the connecting hole is misaligned and closed. Compared with the sealing structure of traditional mechanical valves, the sealing effect is more stable and there is no friction loss. At the same time, the deformation of the elastic ring 4522 has a buffering effect, which can compensate for the slight displacement of the first air inlet pipe 4521 and the second air inlet pipe 4523 due to installation errors and vibrations, ensuring the sealing fit when the connecting hole is aligned, preventing airflow leakage from the gap, and improving the air pressure utilization rate.

[0068] The rotating module 453 includes an outlet seat 4531 connected to one end of the air supply pipe 4524, a combination channel 4532 disposed on the outlet seat 4531, an inner tube 4534 connected to the outlet seat 4531, a rotating shaft 4536 disposed in the outlet seat 4531 and passing through the inner tube 4534, a plurality of placement slots respectively formed on the circumference of the rotating shaft 4536, and an extrusion sheet 4537 located in the placement slots; the rotating shaft 4536 is connected to the rotating shaft 454; there is a gap between the inner tube 4534 and the inner wall of the housing 46; the inner tube 453... The inner tube 4534 is provided with multiple air inlets and multiple air outlets 4562. The extrusion plate 4537 and the rotating shaft 4536 divide the inner tube 4534 into three areas. The air inlets are used to supply air to the area with the largest area, and the air outlets 4562 are connected to the area with the smallest area. The combination channel 4532 includes a U-shaped groove opened in the axial direction of the air outlet seat 4531, and a transport hole for connecting the U-shaped groove and the air supply pipe 4524. A connecting seat 4535 is also provided between the air outlet seat 4531 and the rotating shaft 4536, and the connecting seat 4535 is rotatably connected to the air outlet seat 4531.

[0069] After the air intake module 452 completes the air intake operation, the gas in the air outlet seat 4531 can enter the gap between the inner tube 4534 and the mounting shell 451 through the combination channel 4532, and enter the area enclosed by one of the extrusion plates 4537, the rotating shaft 4536 and the inner tube 4534 through the air intake hole. As the airflow increases, the airflow can push the extrusion plate 4537 to move, and the moving extrusion plate 4537 can gradually retract into the rotating shaft 4536. At this time, along the rotation direction of the rotating shaft 4536, the area between adjacent extrusion plates 4537 gradually decreases. At this time, the moving extrusion plate 4537 can drive the rotating shaft 4536 to move, thereby driving the rotating shaft 4536 to rotate. Through the rotating shaft 454, the adhesive take-up roller 455 can be driven to rotate, thereby completing the adsorption of long strips of waste.

[0070] When the extrusion plate 4537 is fully inserted into the rotating shaft 4536, the rotating shaft 4536 continues to rotate due to inertia or the influence of the extrusion plate 4537. Under the influence of inertia, the extrusion plate 4537 can gradually extend out of the rotating shaft 4536. During this process, it can perform negative pressure adsorption on the airflow, thereby further driving the extrusion plate 4537 and the rotating shaft 4536 to rotate, ensuring the continuity of the entire motion process.

[0071] The exhaust module 456 includes a groove 4561 formed circumferentially on the air outlet seat 4531, an exhaust chamber 4563 formed between the outer wall of the air supply pipe 4524 and the inner wall of the mounting shell 451, a sealing block 4564 sleeved on the air supply pipe 4524, and an exhaust channel 4565 formed on the sealing block 4564. The groove 4561 is used to transport the gas discharged from the exhaust hole 4562 to the exhaust chamber 4563. The exhaust chamber 4563 is connected to the outside through the exhaust channel 4565. During the rotation of the rotating shaft 4536, the gas can enter the exhaust chamber 4563 through the exhaust hole 4562, and at this time the gas can be discharged to the outside through the exhaust channel 4565 to complete the exhaust work. During this process, the mold can still be cooled to ensure the smooth progress of the injection molding.

[0072] In a further embodiment, the air inlet pipe 411 and the first air inlet pipe 4521 are respectively connected to the air pump via flexible hoses, thereby enabling gas delivery. The translation mechanism 2 is existing technology.

[0073] Working principle description: After the injection molding of the micro fan blades is completed, the existing lifting mechanism in the injection molding table 1 applies a thrust to the micro fan blades, allowing them to detach from the mold. Then, the translation mechanism 2 starts working, adjusting the position of the brushing assembly 44. When the brushing assembly 44 is in the predetermined position, the drive assembly 41 starts working. The moving drive assembly 41 drives the push rod 414 to reciprocate along its axis. The moving push rod 414 drives the drive disk 441 to move, and the moving drive disk 441 drives the drive roller 442 to move forward. The moving adjustment rack 443 causes relative displacement between the adjustment rack 443 and the slide rail 446. The moving adjustment rack 443 drives the meshing gear 445 to rotate, which in turn drives the bristles to rotate and complete the brushing work on the inner wall of the hole. When the push rod 414 moves in the opposite direction, the return spring 447 pushes the adjustment rack 443 to move in the opposite direction. At this time, the gear 445 can also rotate in the opposite direction. Therefore, as long as the push rod 414 moves in its axial direction, it can drive the bristles to rotate, thereby completing the brushing work on the inner wall of the hole.

[0074] When the drive component 41 needs to work, the airflow enters the first chamber through the air inlet pipe 411 and the diverter block 412. This causes an increase in pressure at one end of the push rod 414. The increased pressure pushes the push rod 414 to move, and the moving push rod 414 drives the brushing component 44 to work, completing the brushing work of the holes. After the push rod 414 moves a preset distance, the second air outlet 418 connects with the first chamber, completing the exhaust work of the first chamber, so that the airflow can blow the holes and reduce the amount of waste residue in the holes.

[0075] When pushing is required, the airflow is delivered through one of the connecting holes in the diverter block 412. Then, the moving push rod 414 moves to compress the gas in the first channel 417. When the air pressure in the first channel 417 exceeds the preset value, the airflow can impact the magnetic component 413, thereby connecting the magnetic component 413 to the housing 46. At this time, the airflow can enter the first channel 417 through another connecting hole. At this time, one end of the push rod 414 can move towards the end closer to the air inlet pipe 411, thereby enabling the push rod 414 to reciprocate, thereby driving the brushing assembly 44 to perform the brushing work.

[0076] When the adsorption component 45 needs to collect the long strips of waste attached to the bristles, the gas enters the mounting shell 451 through the first air inlet pipe 4521. Since the gas is compressed, it can deform the elastic ring 4522, allowing the gas to enter the gas delivery pipe 4524 through the connection hole, thus completing the gas delivery.

[0077] After the intake module 452 completes its intake operation, the gas in the outlet seat 4531 can enter the gap between the inner tube 4534 and the mounting shell 451 through the combination channel 4532. It can also enter the area enclosed by one of the extrusion plates 4537, the rotating shaft 4536, and the inner tube 4534 through the provided air inlet. As the airflow increases, the airflow pushes the extrusion plate 4537 to move. The moving extrusion plate 4537 gradually retracts into the rotating shaft 4536. Along the rotation direction of the rotating shaft 4536, the area between adjacent extrusion plates 4537 gradually decreases. The moving extrusion plate 4537 can then drive the rotating shaft 4536... The moving shaft 4536 moves, thereby driving the rotating shaft 4536 to rotate. The rotating shaft 454 then drives the viscous take-up roller 455 to rotate, thus completing the adsorption of long strips of waste. When the extrusion plate 4537 is fully inserted into the rotating shaft 4536, the rotating shaft 4536 continues to rotate due to inertia or the influence of the extrusion plate 4537. Under the influence of inertia, the extrusion plate 4537 can gradually extend out of the rotating shaft 4536. During this process, negative pressure adsorption of the airflow can be performed, which can further drive the extrusion plate 4537 and the rotating shaft 4536 to rotate, ensuring the continuity of the entire movement process.

[0078] During the rotation of the rotating shaft 4536, the gas can enter the venting chamber 4563 through the venting hole 4562. At this time, the gas can be discharged into the outside through the venting channel 4565, completing the venting work. During this process, the mold can still be cooled down, ensuring the smooth progress of the injection molding work.
