[0002] With the development of manufacturing industry, molds are more and more widely used, especially in the automotive, electronics and other industries. The requirements for molds are not limited to the accuracy of shape and size, but also involve surface quality, cleanliness and other aspects. During the mold processing, due to the use of cutting fluid, coolant and the generation of metal debris, oil and impurities are easily left on the mold surface, which will affect the quality of the finished product. Therefore, mold cleaning has become an indispensable part of the production process.

[0003] Currently, mold cleaning mainly relies on manual solvent scrubbing. Although this method can effectively remove oil and impurities, manual cleaning is time-consuming and labor-intensive. It is not only time-consuming, but also labor-intensive, and the cleaning quality and consistency are difficult to guarantee. At the same time, long-term exposure to chemical solvents will also pose a safety hazard to human health. Summary of the invention

[0011] By adopting the above technical solution, the positions of the cleaning brush, the reagent tube and the clean water tube are more stable, avoiding displacement or loosening during the cleaning process, thereby improving the cleaning accuracy and reliability. At the same time, the design of the support tube can also protect the first drive motor that drives the support tube to rotate, reducing the damage to the first drive motor caused by sewage falling onto the first drive motor.

[0012] Optionally, the cleaning device further comprises two scrapers fixedly connected to the support tube, and the two scrapers are respectively located on opposite sides of the medicine outlet and the clean water outlet.

[0013] By adopting the above technical solution, a scraper located on the side of the reagent outlet can scrape off large particles of impurities on the mold before cleaning, so that the subsequent cleaning effect is better; a scraper located on the side close to the clean water outlet can scrape off the residual liquid on the surface of the mold, making the mold cleaning more thorough.

[0014] Optionally, two cleaning devices are provided, the axes of the cleaning brushes of the two cleaning devices are vertically arranged, the two cleaning brushes are driven by a bevel gear set, and a second driving motor is also provided to drive the mounting platform to rotate.

[0015] By adopting the above technical solution, the cleaning brushes of the two cleaning devices are arranged vertically, so that the side walls and bottom walls of the mold can be cleaned by different cleaning brushes, thereby improving the cleaning efficiency and cleaning quality; the two cleaning brushes are driven by a bevel gear set, so that when one cleaning brush is working, the other cleaning brush can also rotate synchronously, ensuring the continuity and stability of the cleaning process; a second drive motor is provided to drive the mounting table to rotate, which can adjust the position of the cleaning brush during the cleaning process, further enhancing the uniformity and thoroughness of the cleaning.

[0016] Optionally, the driving device includes a first linear motor installed on opposite sides of the cleaning box, a second linear motor rotatably connected between the two first linear motors, and a driving cylinder fixedly connected to a slider of the second linear motor, wherein both ends of the second linear motor are respectively connected to the sliders of the two first linear motors, and one end of the second linear motor is also provided with a third driving motor for driving the second linear motor to rotate; the second driving motor is fixedly connected to the slider of the second linear motor, and the mounting platform is fixedly connected to the piston rod of the driving cylinder.

[0017] By adopting the above technical solution, the driving device realizes precise control of multiple degrees of freedom, so that the cleaning device can move flexibly in multiple directions, thereby ensuring the comprehensiveness and efficiency of the cleaning process. Specifically, the combined design of the first linear motor and the second linear motor enables the cleaning device to be precisely adjusted in the horizontal and vertical directions, while the driving cylinder can drive the cleaning device to rise and fall in the vertical direction to meet the cleaning requirements of molds of different depths; the third driving motor can drive the entire cleaning device to rotate, so that the cleaning device can clean the cleaning bucket.

[0018] Optionally, a mounting block is fixedly connected to the slider of the first linear motor, a rotating rod is rotatably connected inside the mounting block, the second linear motor is fixedly connected to the rotating rod, and a limiting component is provided between the mounting block and the rotating rod to fix the relative positions of the two.

[0019] By adopting the above technical solution, under normal circumstances, the relative positions of the rotating rod and the mounting block can be fixed by the limit assembly, and the installation angle of the cleaning device can be fixed; when the installation angle of the cleaning device needs to be changed, the fixing relationship between the limit assembly and the mounting rod and the mounting block is directly released, and the second linear motor can be driven to rotate by the second linear motor to change the installation angle of the cleaning device, so that the cleaning device can be transformed from cleaning the mold to cleaning the cleaning box.

[0020] Optionally, a mounting groove is provided on the inner wall of the mounting block, and the limit assembly includes a limit spring fixed in the mounting groove and a limit block fixed to the limit spring at one end away from the bottom of the mounting groove, and a fixing groove for embedding the limit block is provided on the outer wall of the rotating rod, and a power part is also provided in the mounting groove for driving the limit block to slide into the mounting groove to release the relative relationship between the mounting block and the rotating rod.

[0021] By adopting the above technical solution, the relative position between the mounting block and the rotating rod can be reliably fixed by the limit assembly, ensuring the stability of the equipment during operation. Specifically, the design of the limit spring and the limit block enables the rotating rod to be firmly engaged when it needs to be fixed, avoiding position deviation caused by vibration or external force. The introduction of the power part further improves the flexibility of the system, and the limit between the rotating rod and the mounting block can be quickly released when the position of the rotating rod needs to be adjusted, which facilitates the maintenance and adjustment of the equipment.

[0022] Optionally, the power member includes a first electromagnet fixedly connected to the bottom of the installation groove and an iron sheet fixedly connected to one end of the limiting block facing the bottom of the installation groove.

[0023] By adopting the above technical solution, when the relative relationship between the mounting block and the rotating rod needs to be released, the first electromagnet is energized to attract the iron sheet, thereby driving the limit block to retract into the mounting groove to disengage from the fixed groove, thereby realizing the free rotation of the rotating rod relative to the mounting block, and improving the flexibility and convenience of operation of the device. When the relative relationship between the mounting block and the rotating rod needs to be fixed, the first electromagnet is directly operated to lose power, so that the first electromagnet can release the adsorption of the iron sheet, and the limit block is embedded in the fixed groove again under the elastic force of the limit spring, fixing the fixed relationship between the rotating rod and the mounting block.

[0024] Optionally, the support frame is L-shaped as a whole, including a support plate hinged on the cleaning box and a frame-shaped support frame fixed to one side of the support plate. When the support frame is rotated to the cleaning box, the support frame abuts against the open end of the cleaning box, and the cleaning device faces the support frame.

[0025] By adopting the above technical solution, the overall design of the support frame enables the mold to remain stable during the cleaning process, avoiding the problem of incomplete cleaning due to mold shaking. The L-shaped support frame is not only convenient for loading and unloading the mold, but also ensures the accurate positioning of the mold during the cleaning process, improving the cleaning efficiency and quality. When the support frame rotates to the top of the cleaning box, the support frame is tightly abutted against the opening of the cleaning box to prevent leakage of the cleaning liquid, while also protecting the cleaning environment and avoiding pollution.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application embodiment discloses an injection molding machine. Figure 1 and Figure 2The injection molding machine includes an operating table 01, an injection molding machine body 02 installed on the operating table 01, a receiving belt 03 arranged under the operating table 01, and a cleaning mechanism arranged at one end of the receiving belt 03 away from the operating table 01. The injection molding machine body 02 includes an injection molding machine head 021 installed on the operating table 01, a fixed mold 022 connected to the injection molding machine head 021, a movable mold 023 slidably connected to the operating table 01, and a driving cylinder 024 fixed to the operating table 01 for driving the movable mold 023 to slide. A forming space for forming a workpiece is formed between the movable mold 023 and the fixed mold 022, and one end of the injection molding machine head 021 away from the fixed mold 022 is connected to the previous process, and is used to transport the melted plastic solution in the previous process to the forming space to realize the forming of the workpiece. The driving cylinder 024 can drive the movable mold 023 to slide in a direction close to or away from the movable mold 023, so that the forming space is opened or closed. When the fixed mold 022 and the movable mold 023 need to be cleaned, the movable mold 023 and the movable mold 023 can be disassembled and transported to the cleaning mechanism through the receiving belt 03 so as to be cleaned by the cleaning mechanism.

[0036] In order to facilitate the disassembled movable mold 023 and fixed mold 022 to reach the receiving belt 03 smoothly, a drop opening 011 is provided on the operating table 01 for the movable mold 023 and the fixed mold 022 to drop onto the receiving belt 03 .

[0037] The cleaning mechanism includes a cleaning box 1, a cleaning device 2 installed in the cleaning box 1, a driving device 3 installed in the cleaning box 1 for driving the cleaning device 2 to move, and a support frame 4 rotatably connected to one side of the cleaning box 1. The support frame 4 is L-shaped as a whole, so that the support frame 4 can be rotated to one end outside the cleaning box 1 so that the mold to be cleaned can be placed on the support frame 4, and the support frame 4 can also be rotated to one end directly above the cleaning box 1 so that the cleaning device 2 located in the cleaning box 1 can clean the mold placed on the placement frame. A conveying device 5 and a discharge device 6 are also provided. One end of the conveying device 5 is connected to the receiving belt 03 to receive the disassembled mold to be cleaned, and the other end is abutted against the support frame 4 to transport the mold to be cleaned to the support frame 4; one end of the discharge device 6 is abutted against the support frame 4 to receive the cleaned mold on the support frame 4. When in use, the mold to be cleaned is transported to the support frame 4 through the conveying device 5, and then the support frame 4 is turned over so that one end of the support frame 4 is located directly above the cleaning box 1, which can drive the mold 023 to be located directly above the cleaning box 1, and the mold can be cleaned by the cleaning device 2, and the driving device 3 drives the cleaning device 2 to move to achieve cleaning of various positions of the mold. After cleaning, the support frame 4 rotates in the opposite direction and resets, which can drive the cleaned mold to move from directly above the cleaning box 1 to the side of the cleaning box 1, and then the cleaned mold is re-transported to the receiving belt 03 through the unloading device 6, so that the mold can be replaced again.

[0038] It is understandable that each injection molding machine can have two sets of molds so that they can be used interchangeably. The mold to be cleaned is transported to the cleaning mechanism via the receiving belt 03, and the mold that has been cleaned by the cleaning mechanism will also be transported to the operating table 01 again via the receiving belt 03, waiting for the next replacement.

[0039] Each injection molding machine is provided with a receiving belt 03, and the end of the conveying device 5 away from the support frame 4 is connected to the ends of multiple receiving belts 03, so that the molds on all injection molding machines can be automatically cleaned through the same cleaning mechanism.

[0040] Among them, the receiving belt 03 can be selected as a belt conveyor. This is the existing technology, and this application will not elaborate on the structure of the belt conveyor.

[0041] It is understandable that when the mold is conveyed to the support frame 4 by the conveying device 5, the opening of the mold faces the support frame 4, and when the support frame 4 drives the mold to flip, the mold opening will face downward, so that the cleaning device 2 in the cleaning box 1 is just located inside the mold.

[0042] Reference Figure 3 , Figure 4 and Figure 5The cleaning box 1 is a box body with an upper end opened, and the cleaning device 2 includes a mounting platform 21 mounted on the cleaning box 1, a cleaning brush 22 mounted on the mounting platform 21, a chemical tube 23 mounted on the mounting platform 21 and located on one side of the cleaning brush 22, a clean water tube 24 mounted on the mounting platform 21 and located on the other side of the cleaning brush 22, and a first driving member 25 mounted on the mounting platform 21 for driving the cleaning brush to rotate. Among them, the end of the chemical tube 23 close to the cleaning brush is a chemical outlet 231, and the end of the clean water tube 24 close to the cleaning brush is a clean water outlet 241. When in use, the other end of the chemical tube 23 is connected to an external cleaning chemical, and the other end of the clean water tube 24 is connected to an external water source. The first driving member 25 can drive the cleaning brush 22 to rotate, and the driving device 3 can drive the cleaning brush 22 to move. During the cleaning process, the agent tube 23 first sprays the cleaning agent into the mold, and then the cleaning brush 22 cleans the inside of the mold through the agent on the mold. After cleaning, the clean water pipe 24 sprays clean water on the cleaned mold to wash away the agent. During the cleaning process, the first driving member 25 always drives the cleaning brush 22 to rotate, so that the cleaning of the mold is more thorough.

[0043] The first driving member 25 includes a first driving motor 251 fixedly connected to the mounting platform 21, and the cleaning brush 22 is fixedly connected to the output shaft of the first driving motor 251, so that the first driving motor 251 can drive the cleaning brush 22 to rotate. A support tube 26 is fixedly connected to the mounting platform 21, and the support tube 26 is sleeved on the first driving motor 251 and abuts against the side of the cleaning brush 22 away from the bristles, so that the first driving motor 251 can be protected by the support tube 26. The medicine tube 23 and the clean water pipe 24 are respectively fixedly connected to the outer walls of the support tube 26 on both sides opposite to each other. It can be understood that the ends of the medicine tube 23 and the clean water pipe 24 fixedly connected to the support tube 26 are hard pipes, which can fix the outlet positions of the medicine tube 23 and the clean water pipe 24; and the ends of the medicine tube 23 and the clean water pipe 24 away from the outlet are soft pipes, so that the positions of the medicine outlet 231 and the clean water outlet 241 can be adapted to the position movement driven by the driving device 3.

[0044] Reference Figure 4 and Figure 5The cleaning device 2 also includes two scrapers 27 fixedly connected to the support tube 26, and the two scrapers 27 are respectively located on the opposite sides of the agent outlet 231 and the clean water outlet 241, so that when the cleaning brush 22 is driven by the driving device 3 to move to clean the mold, a scraper 27 located at the end of the agent outlet 231 away from the clean water outlet 241 can first scrape off the large particles of impurities inside the mold, and then the agent pipe 23 transports the external agent to the agent outlet 231, and sprays the agent into the mold through the agent outlet 231; then the cleaning brush 22 cleans the mold, and after cleaning, the external clean water is transported to the mold through the clean water outlet 241 to clean the agent on the mold; finally, the clean water on the mold is scraped off by a scraper 27 located at the end of the clean water outlet 241 away from the agent outlet 231 to complete the cleaning of the mold.

[0045] There may be two cleaning devices 2, the axes of the cleaning brushes 22 of the two cleaning devices 2 are vertically arranged, and an auxiliary cylinder 28 is vertically connected to one side of the support cylinder 26, the other cleaning brush 22 is rotatably connected in the auxiliary cylinder 28, and the two cleaning brushes 22 are connected through a bevel gear set 29. Thus, a first driving motor 251 can simultaneously drive the two cleaning brushes 22 to rotate through the bevel gear set 29, and can also simultaneously drive the two cleaning devices 2 to move through a driving device 3.

[0046] Reference Figure 5 The driving device 3 includes a first linear motor 31 installed on opposite sides of the cleaning box 1, a second linear motor 32 rotatably connected between the two first linear motors 31, and a driving cylinder 33 fixedly connected to the slider of the second linear motor 32. The mounting platform 21 is fixedly connected to the piston rod of the driving cylinder 33. The two ends of the second linear motor 32 are respectively connected to the sliders of the two first linear motors 31, and a second driving motor 34 for driving the driving cylinder 33 to rotate is fixedly connected to the slider of the second linear motor. When in use, the cleaning device 2 can be driven to move along the length direction of the cleaning box 1 directly through the first linear motor 31, and the cleaning device 2 can be driven to move along the width direction of the cleaning box 1 through the second linear motor 32. The cleaning brush 22 can be driven to rise and fall through the driving cylinder 33 to clean the mold at different heights; the two cleaning devices 2 can be driven to rotate synchronously through the second driving motor 34, so that the outer wall of the mold in different directions can be cleaned by the same cleaning brush 22, and the operation is more flexible.

[0047] It is understandable that the chemical pipes 23 and the clean water pipes 24 on the two cleaning devices 2 are controlled by different valves, so that when the cleaning brush 22 at the auxiliary cylinder 28 cleans the side wall of the mold, the chemical pipes 23 and the clean water pipes 24 on the side wall of the support cylinder 26 are closed and in a rest state. When the bottom wall and the side wall of the bottom of the mold are cleaned at the same time by the two cleaning brushes 22, the chemical pipes 23 and the clean water pipes 24 on the two cleaning devices 2 are opened. When the bottom of the mold is cleaned by the cleaning brush 22 on the support cylinder 26, the chemical pipes 23 and the clean water pipes 24 fixed to the auxiliary cylinder 28 are closed. So that the four side walls and the bottom of the mold can be cleaned by the two cleaning brushes 22, and the cleaning is more convenient.

[0048] Reference Figure 5 and Figure 6 , a mounting block 35 is fixedly connected to the slider of each first linear motor 31, a rotating rod 36 is rotatably connected in the mounting block 35, the second linear motor 32 is fixedly connected to the rotating rod 36, and a third driving motor 37 for driving the second linear motor 32 to rotate is fixedly connected to the end of the mounting block 35 away from the second linear motor 32, and a limiting assembly 38 for fixing the relative position of the mounting block 35 and the rotating rod 36 is provided between the mounting block 35 and the rotating rod 36. Under normal conditions, the relative position of the mounting block 35 and the rotating rod 36 can be fixed by the limiting assembly 38, so that the first linear motor 31 can smoothly drive the second linear motor 32 to rotate, and the cleaning brush 22 can clean the mold. When cleaning the mold, impurities and cleaning wastewater on the mold will fall into the cleaning box 1 under the action of gravity. When the cleaning box 1 is used for a period of time and needs to be cleaned regularly, the fixing relationship between the mounting block 35 and the rotating rod 36 by the limit assembly 38 can be released, and the rotating rod 36 is driven by the third driving motor 37 to rotate the set angle relative to the mounting ring, and then the mounting block 35 and the rotating rod 36 are fixed by the limit assembly 38. At this time, the cleaning device 2 will be located inside the cleaning box 1, and the cleaning box 1 can be cleaned by the cleaning device 2.

[0049] Reference Figure 3 A sewage outlet 11 is provided on one side of the cleaning box 1, and a sewage pipe 12 is installed at the sewage outlet 11, so that impurities reaching the cleaning box 1 can be discharged through the sewage outlet 11. When there are too many stains in the cleaning box 1, the cleaning device 2 can be used to clean the inside of the cleaning box 1.

[0050] Reference Figure 6, a mounting groove 351 is provided on the inner wall of the mounting block 35, and the limiting assembly 38 includes a limiting spring 381 fixed in the mounting groove 351, a limiting block 382 fixed to one end of the limiting spring 381 away from the mounting groove 351, and a power member 383 arranged between the bottom of the limiting groove 411 and the limiting block 382 for driving the limiting block 382 to slide in the mounting groove 351; at the same time, a fixing groove 361 for the limiting block 382 to be embedded is provided on the outer wall of the rotating rod 36. Under normal conditions, the limiting block 382 can be embedded in the fixing groove 361 under the elastic force of the limiting spring 381, thereby fixing the relative position between the rotating rod 36 and the fixing block. When it is necessary to adjust the installation angle of the cleaning brush 22, the limiting block 382 can be operated by the power member 383 to slide into the mounting groove 351, thereby releasing the matching relationship between the limiting block 382 and the fixing groove 361. At this time, the third driving motor 37 can be used to drive the second linear motor 32 to rotate, so as to adjust the installation angle of the cleaning brush 22. After the adjustment is completed, the restriction relationship between the power member 383 and the limit block 382 is released, so that the limit block 382 can be re-embedded in the fixing groove 361 under the elastic force of the limit spring 381, so as to fix the position relationship between the installation block 35 and the rotating rod 36.

[0051] Specifically, the power member 383 includes a first electromagnet 3831 fixedly connected to the bottom of the mounting groove 351 and an iron sheet 3832 fixedly connected to one end of the limit block 382 facing the bottom of the mounting groove 351, and the limit spring 381 is sleeved on the first electromagnet 3831. When the first electromagnet 3831 is energized, the first electromagnet 3831 will adsorb the iron sheet 3832, thereby driving the limit block 382 to retract into the mounting groove 351. When the operating rotating rod 36 is rotated relative to the mounting block 35 by a set angle, the first electromagnet 3831 is directly controlled to lose power, so that the adsorption relationship between the first electromagnet 3831 and the iron sheet 3832 can be released.

[0052] Reference Figure 3 A fourth drive motor 13 for driving the support frame 4 to rotate is also provided on one side of the cleaning box 1 , and the output shaft of the fourth drive motor 13 is fixedly connected to the rotating shaft of the support frame 4 .

[0053] Reference Figure 2 and Figure 3The support frame 4 is L-shaped as a whole, including a support plate 41 and a frame-shaped support frame 42 fixed to one side of the support plate 41. The support frame 42 is located on the side close to the cleaning box 1, and a support table 14 for supporting the support plate 41 is fixed to one side of the cleaning box 1. Under normal conditions, the support plate 41 is located on one side of the cleaning box 1 and is placed on the support table 14 to receive the mold to be cleaned. When the mold reaches the support plate 41, one side of the mold abuts against the support frame 42. Then, the fourth driving motor 13 drives the support frame 4 to rotate, so that the support frame 42 abuts against the top of the cleaning box 1. At this time, the mold is also placed on the support frame 42, and the mold is supported by the support frame 42.

[0054] In order to fix the position of the mold on the support frame 42, a slot 421 is provided on the side of the support frame 42 facing the support plate 41, so that when the support frame 42 supports the mold, the mold is located in the slot 421, thereby fixing the position of the mold on the support frame 42.

[0055] Reference Figure 2 and Figure 3 The conveying device 5 includes a first belt conveyor 51 located on the side of the support platform 14 away from the cleaning box 1, one end of the first belt conveyor 51 is in contact with the support platform 14, and when the support plate 41 is placed on the support platform 14, the upper surface of the support plate 41 is flush with the upper surface of the first belt conveyor 51, so that the mold transported by the first belt conveyor 51 can smoothly reach the support plate 41.

[0056] The unloading device 6 includes an unloading cylinder 61 fixedly connected to one end of the support platform 14, a push plate 62 fixedly connected to the piston rod of the unloading cylinder 61, and a second belt conveyor 63 arranged at one end of the support platform 14 away from the unloading cylinder 61. After the cleaning of the mold is completed, the support frame 4 is operated to flip and reset. At this time, the support plate 41 is located on the support platform 14, and the push plate 62 is located directly above one side of the support plate 41. Then the unloading cylinder 61 is controlled to start, and the push plate 62 is driven by the unloading cylinder 61 to push the mold on the support plate 41 onto the second belt conveyor 63 to complete the unloading work. The second belt conveyor 63 can be set to be connected to the receiving belt 03, so that the cleaned mold can be transported to the injection molding machine body 02 again through the receiving belt 03, waiting for the replacement and cleaning of the mold.

[0057] In order to enable the push plate 62 to smoothly push out the mold located in the slot 421, the upper surface of the support platform 14 is set to be inclined. The height of the support platform 14 near the end of the cleaning box 1 is higher than the height near the end of the conveying device 5. The inclination angle of the upper surface of the support platform 14 can be 3-10 degrees. This application takes the upper surface of the support platform 14 inclined at 5 degrees as an example for explanation. A limiting groove 411 connected to the slot 421 is also provided on the support plate 41. When the support plate 41 is reset to the position where the support plate 41 is placed on the support platform 14, the mold also slides downward along the height of the upper surface of the support plate 41 under the action of inertia until it abuts against one end of the limiting groove 411. At this time, the mold also slides from the slot 421, and the mold can be smoothly pushed out of the support platform 14 by the push plate 62.

[0058] At the same time, a second electromagnet 412 is installed at the bottom of the limiting groove 411, so that when the support frame 42 abuts against the cleaning box 1 to support the mold, the second electromagnet 412 is also adsorbed on the mold, thereby making the positioning of the mold more accurate.

[0059] Reference Figure 2 and Figure 5 A first contact switch 15 is also installed on the cleaning box 1. The first contact switch 15 is located on a side away from the hinge axis of the support frame 4, so that when the support frame 4 rotates until the support frame 42 abuts against the cleaning box 1, the side wall of the support frame 42 at one end away from its own hinge axis will abut against the first contact switch 15 to limit the rotation position of the support frame 4.

[0060] At the same time, in order to fix the position of the support frame 4 when it is reset, a second contact switch 16 is installed on the support platform 14, so that when the support frame 4 rotates and resets until the support plate 41 abuts against the second contact switch 16, the fourth drive motor 13 is controlled to stop to fix the position of the support frame 4.

[0061] The implementation principle of the injection molding machine of the embodiment of the present application is as follows: when in use, the disassembled mold to be cleaned reaches the receiving belt 03 through the drop port 011, is transported to the first belt conveyor 51 through the receiving belt 03, and then is transported to the support plate 41 by the first belt conveyor 51, and then the support frame 4 is driven to rotate by the fourth drive motor 13, so that the support frame 42 abuts against the first contact switch 15, and the fourth drive motor 13 stops at this time. At this time, the mold is located in the card slot 421 of the support frame 42, and then the mold is adsorbed by the second electromagnet 412, so as to fix the position of the mold on the support frame 42. The cleaning brush 22 can be driven to move by the drive device 3 to realize the automatic cleaning of the inside of the mold. After cleaning is completed, the fourth drive motor 13 drives the support frame 4 to rotate in the opposite direction until the support plate 41 abuts against the second contact switch 16. At this time, the fourth drive motor 13 stops, and the mold flips onto the support plate 41 and slides downward along the inclination angle of the support plate 41 until it abuts against one side of the limit groove 411, so that the mold slides out of the slot 421. At this time, by controlling the piston rod of the unloading cylinder 61 to extend, the cleaned mold can be pushed onto the second belt conveyor 63 through the push plate 62, so that the cleaned mold can be transported away by the second belt conveyor 63. The first belt conveyor 51 then transports the next mold to be cleaned to the support plate 41, and the cycle is repeated in sequence to achieve automatic cleaning of the mold. When there are many stains in the cleaning box 1, the second electromagnet 412 can be controlled to be energized to adsorb the limit block 382 into the installation groove 351 through the iron sheet 3832, and then the second linear motor 32 is driven to rotate by the third drive motor 37 to drive the cleaning device 2 to rotate 180 degrees as a whole, so that the cleaning device 2 can clean the inside of the cleaning box 1, making cleaning more convenient.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
