[0002] In the plastics processing industry, traditional injection molding machines are key equipment for producing various plastic products. Their working efficiency and product quality directly affect the company's production benefits and market competitiveness. During the injection molding process, the mold, as the core component for molding plastic parts, directly determines the product's precision, surface finish, and production efficiency.
[0003] For a long time, after injection molding, molds often retain residual plastic melt, additives, and other impurities. These residues not only affect the quality of subsequent injection molded products, causing surface defects and dimensional deviations, but can also lead to accelerated mold wear, shortened mold lifespan, and increased maintenance and replacement costs for companies due to their accumulation. Currently, most injection molding machines on the market rely on manual cleaning after mold disassembly, but these methods have significant limitations. Manual cleaning not only depends on manual operation, which is inefficient, but also makes it difficult to ensure thorough cleaning of the complex internal structure of the mold, and it cannot meet the needs of large-scale, continuous production.
[0004] Therefore, it is necessary to provide an injection molding machine with an automatic cleaning function that can effectively clean the mold. Utility Model Content

[0047] Please refer to Figure 1 - Figure 4 One embodiment of this application provides an injection molding machine 100 with an automatic cleaning function. The injection molding machine 100 includes a stamping part 10, which is provided with a drive part 11, a guide rod 12, a fixed template 13, a moving template 14, and a first air gun 15.
[0048] The guide rod 12 is fixedly connected to the drive unit 11. The fixed template 13 is fixedly connected to the guide rod 12 and is located on the side of the guide rod 12 away from the drive unit 11. The fixed template 13 is fixedly connected to a first mold. The movable template 14 is slidably connected to the guide rod 12 and is located between the drive unit 11 and the fixed template 13. The movable template 14 is fixedly connected to a second mold. Viewed horizontally, the first air gun 15 is fixedly connected to the movable template 14 and is located on the side of the movable template 14 where the second mold is fixedly connected, and is located above the second mold. When the drive unit 11 drives the movable template 14 to move along the guide rod 12 towards the side away from the fixed template 13, the first air gun 15 sprays air into the first mold.
[0049] When the moving template 14 moves along the guide rod 12 in a direction away from the fixed template 13, a certain gap is generated between the first mold and the second mold. At this time, the first air gun 15, fixed to the moving template 14 and located above the second mold, can directly spray air onto the first mold for cleaning. This arrangement allows the cleaning action to be synchronized with the mold opening and closing action, eliminating the need for additional operating steps or equipment, thereby improving cleaning efficiency and convenience. Fixing the first air gun 15 to the moving template 14 and positioning it above the second mold fully utilizes the space gap during mold opening and closing, avoiding additional occupation of the overall structure of the injection molding machine 100. This compact layout helps reduce the footprint of the injection molding machine 100, while also helping to reduce manufacturing costs and maintenance difficulty. Because the first air gun 15 is located above the second mold and can directly spray air onto the first mold when the moving template 14 moves, the uniformity and coverage of the cleaning airflow can be ensured. This arrangement helps to thoroughly remove residues from the mold, improving mold cleanliness and service life. By electrically connecting or linking the first air gun 15 with components such as the drive unit 11, the injection molding machine 100 can achieve automated cleaning. In actual production, parameters such as cleaning time and frequency can be set as needed to achieve intelligent cleaning control.
[0050] More preferably, the stamping part 10 further includes a second air gun 16.
[0051] Viewed horizontally, the second air gun 16 is fixedly connected to the fixed template 13 and located on the side of the fixed template 13 where the first mold is fixedly connected, with the second air gun 16 positioned above the second mold. When the first air gun 15 sprays air into the first mold, the second air gun 16 also sprays air into the second mold.
[0052] In this system, while the first air gun 15 sprays air into the first mold for cleaning, the second air gun 16 simultaneously sprays air into the second mold. This synchronized cleaning method significantly shortens the cleaning cycle and improves overall production efficiency. By placing the second air gun 16 above the second mold, it is ensured that the second mold also receives thorough cleaning. This helps prevent residues inside the mold from affecting the quality of the injection-molded product, ensuring product stability and consistency. The second air gun 16 is fixedly connected to the fixed platen 13, making full use of the space structure during mold opening and closing. This layout is not only compact but also avoids additional space occupation, making the overall structure of the injection molding machine 100 more rational. The addition of the second air gun 16 makes the cleaning process of the injection molding machine 100 more automated and intelligent. Operators do not need to manually switch or adjust the cleaning equipment, thus reducing operational difficulty and labor costs. This setup makes the injection molding machine 100 more flexible in handling molds of different types and sizes. Both the first and second molds receive thorough cleaning, expanding the application range of the injection molding machine 100.
[0053] More preferably, the stamping part 10 further includes a pressure sensor 17.
[0054] The pressure sensor 17 is located on the guide rod 12. The pressure sensor 17 is electrically connected to the first air gun 15 and also electrically connected to the second air gun 16. When the moving template 14 moves along the guide rod 12 to the pressure sensor 17, the pressure sensor 17 controls the first air gun 15 and the second air gun 16 to spray air.
[0055] The cleaning function of the injection molding machine 100 is automated through precise control of the pressure sensor 17. When the moving platen 14 moves to the designated position, the pressure sensor 17 automatically triggers the air-jet cleaning action without manual intervention, thereby improving production efficiency. The pressure sensor 17 can accurately sense the moving position of the moving platen 14, and only triggers air-jet cleaning when the moving platen 14 contacts the pressure sensor 17. This precise triggering mechanism avoids unnecessary energy waste and reduces energy consumption. During mold opening and closing, the setting of the pressure sensor 17 ensures that air-jet cleaning is performed only after the mold is completely separated, avoiding direct impact and damage to the mold from the cleaning airflow, thereby extending the mold's service life. Through the precise control of the pressure sensor 17, the cleaning airflow can be ensured to be sprayed when the mold is completely separated and the residue inside the mold is most easily removed. This setting helps to improve the cleaning effect, reduce residue inside the mold, and thus ensure the quality and stability of the injection molded products. The electrical connection between the pressure sensor 17 and the first air gun 15 and the second air gun 16 makes the entire cleaning system more stable and reliable. Through precise electrical control, equipment damage and downtime caused by mechanical failure or misoperation are reduced.
[0056] More preferably, the injection molding machine 100 further includes a collection tank 20.
[0057] Viewed horizontally, the collection trough 20 is located below the moving template 14. The collection trough 20 collects waste material that falls from the first mold and the second mold after air jetting.
[0058] During the air-jet cleaning process, some residue or waste may fall inside the mold. By setting up a collection trough 20, this waste can be effectively collected, preventing it from scattering within the working area of the injection molding machine 100, thus maintaining a clean and orderly working environment. The collection trough 20 centrally collects waste, making waste recycling and disposal more convenient. Operators can regularly clean the collection trough 20 to recycle or properly dispose of the waste, meeting environmental protection requirements. If waste is scattered on critical components or moving areas of the injection molding machine 100, it may damage the equipment or affect its normal operation. The collection trough 20 prevents this from happening, protecting the integrity and stability of the injection molding machine 100. Maintaining a clean working environment and stable equipment operation helps improve the production efficiency of the injection molding machine 100. Operators can focus more on the injection molding process itself without spending extra time and effort cleaning up waste or dealing with equipment malfunctions. The design of the collection trough 20 is part of the overall performance improvement of the injection molding machine 100. It works in conjunction with other components (such as pressure sensor 17, air gun, etc.) to form an efficient, stable, and environmentally friendly injection molding system.
[0059] More preferably, the injection molding machine 100 further includes a base 30.
[0060] The base 30 is fixedly connected to the stamping part 10, and when viewed horizontally, the base 30 is located below the stamping part 10, and the base 30 supports the injection molding machine 100.
[0061] The base 30, serving as the support structure for the injection molding machine 100, significantly enhances the stability of the machine during operation. It prevents the machine from shaking or shifting due to vibration or external forces, thus ensuring the accuracy and reliability of the injection molding process. The injection molding machine 100 typically has a large weight and volume; placing it directly on the ground could damage or leave indentations. The base 30 effectively distributes the weight of the machine, protecting the ground from damage. The base 30 usually features standard mounting interfaces and adjustment functions, simplifying the installation and commissioning of the injection molding machine 100. Operators can adjust the height and level of the base 30 according to actual needs, ensuring the machine reaches its optimal working condition. The design of the base 30 often considers the overall aesthetics of the injection molding machine 100. By selecting appropriate materials, colors, and shapes, the base 30 can coordinate with other components of the machine, creating a clean and aesthetically pleasing working environment.
[0062] More preferably, the injection molding machine 100 further includes a feeding unit 40 and a control panel 50.
[0063] The feeding section 40 is fixedly connected to the stamping section 10 and connected to the base 30. The control panel 50 is fixedly connected to the feeding section 40 and electrically connected to the drive section 11. The control panel 50 controls the operation of the drive section 11.
[0064] The feeding unit 40 is fixedly connected to the stamping unit 10 and the base 30, ensuring a stable and continuous supply of raw materials to the stamping unit 10. This arrangement achieves automated feeding, reduces manual intervention, and improves production efficiency. Integrating the feeding unit 40 with the stamping unit 10 and the base 30 helps reduce the floor space and optimize spatial layout. This compact structure makes the injection molding machine 100 more aesthetically pleasing and tidy. The fixed connection between the feeding unit 40, the stamping unit 10, and the base 30 allows maintenance personnel to more easily inspect and repair the feeding system, reducing maintenance difficulty and costs. The control panel 50 is fixedly connected to the feeding unit 40 and electrically connected to the drive unit 11, enabling centralized control of the overall operation of the injection molding machine 100. Operators can conveniently monitor the status of the injection molding machine 100 and adjust operating parameters through the control panel 50 to ensure smooth production. The design of the control panel 50 typically takes into account the comfort and convenience of the operator. With its rational layout and user-friendly interface design, the control panel 50 allows operators to operate the injection molding machine 100 more conveniently, improving work efficiency. The control panel 50 can also be equipped with various safety protection devices and alarm systems to ensure operators work in a safe environment. When the injection molding machine 100 malfunctions or experiences an abnormal situation, the control panel 50 can promptly issue an alarm to remind the operator to take appropriate measures.
[0065] More preferably, the feeding unit 40 further includes: a propeller pusher 41 and a support frame 42.
[0066] The propeller pusher 41 is fixedly connected to the stamping part 10. The support frame 42 is fixedly connected to the base 30 and is located between the base 30 and the propeller pusher 41.
[0067] The propeller pusher 41 is fixedly connected to the stamping section 10, ensuring the stability and continuity of the feeding process. This arrangement allows the propeller pusher 41 to precisely control the conveying speed and quantity of raw materials, thereby meeting the precise requirements of raw materials during injection molding. The propeller pusher 41 pushes the raw materials from the storage area to the stamping section 10 through rotation or reciprocating motion. This pushing method is not only efficient but also ensures uniform delivery of raw materials, avoiding blockages or accumulation. The support frame 42 is fixedly connected to the base 30, providing stable support for the propeller pusher 41. This arrangement ensures the stability and reliability of the propeller pusher 41 during operation, preventing displacement or damage caused by vibration or external forces. The support frame 42 is located between the base 30 and the propeller pusher 41, playing a crucial role in connecting the two. It can not only transmit the fixing force on the base 30 to the propeller pusher 41, but also withstand the reaction force generated by the propeller pusher 41 during operation, thereby ensuring the stability and durability of the entire feeding section 40.
[0068] More preferably, the feeding unit 40 further includes a feeding mechanism 43.
[0069] The feeding mechanism 43 is equipped with a pipe and is located on the side of the propeller pusher 41 opposite to the support frame 42. The pipe is located between the feeding mechanism 43 and the propeller pusher 41, and the pipe conveys material to the propeller pusher 41.
[0070] The feeding mechanism 43 includes a pipe located between itself and the propeller pusher 41, used to convey material to the propeller pusher 41. This arrangement ensures that the material is continuously and stably conveyed to the propeller pusher 41 and then pushed to the stamping section 10 for injection molding. The feeding mechanism 43 is located on the side of the propeller pusher 41 away from the support frame 42. This layout avoids interference with the support frame 42 and ensures the compact structure and efficient operation of the feeding section 40. This arrangement also facilitates inspection and maintenance of the feeding section 40 by operators and maintenance personnel. Conveying material through the pipe allows for precise control of the material delivery volume and speed. This helps ensure the uniformity and stability of the raw material during injection molding, thereby improving the quality and consistency of the injection molded products. The close cooperation between the feeding mechanism 43 and the propeller pusher 41 reduces material waste during the conveying process. The pipe design also helps prevent material leakage or spillage, thus reducing production costs. The automated feeding mechanism 43, combined with the propeller pusher 41, achieves automation and continuity of the feeding process. This greatly improves production efficiency, shortens the production cycle, and meets the modern demand for high efficiency and speed in plastic product manufacturing.
[0071] More preferably, the feeding unit 40 further includes a motor 44. The motor 44 is fixedly connected to the propeller pusher 41, and the motor 44 drives the propeller pusher 41 to rotate.
[0072] Among them, the motor 44, as the power source, is stable and reliable. It can continuously and evenly provide driving force, ensuring that the propeller pusher 41 can rotate stably, thereby achieving continuous material conveying. The motor 44 drive system typically has high control precision. By adjusting the speed and direction of the motor 44, the rotation speed and direction of the propeller pusher 41 can be precisely controlled, thereby meeting the precise requirements for material conveying during injection molding. The motor 44 drive system is easy to integrate with automated control systems. Through programming and controller settings, the automated operation of the feeding section 40 can be achieved, reducing manual intervention and improving production efficiency.
[0073] Therefore, by providing a first air gun 15 on the moving platen 14, the injection molding machine 100 can effectively clean the mold. Furthermore, the design of the first air gun 15 spraying air onto the first mold after the moving platen 14 is moved along the guide rod 12 away from the fixed platen 13 by the drive unit 11 allows the injection molding machine 100 to automatically clean the first mold via the first air gun 15 when the fixed platen 13 and the moving platen 14 are separated.
[0074] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this 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 application, and these modifications and improvements all fall within the protection scope of this application.
