Description

Technical Field

[0001] This utility model relates to the field of mold cleaning technology, and in particular to a cleaning structure for the surface of a plastic mold cavity. Background Technology

[0002] As the core component of injection molding, the quality of the mold directly determines the precision, appearance, and performance of the final plastic product; and the cleanliness of the mold cavity surface is one of the key factors affecting the quality of the mold and the plastic product. During the continuous process of injection molding, various impurities inevitably accumulate inside the mold cavity. If these impurities are not cleaned in time, they will have many negative impacts on the quality of subsequent plastic parts. Currently, for some molds with shallow cavities, traditional cleaning methods, such as manual cleaning with brushes and air guns, can achieve a certain degree of cleaning effect. However, for some molds with deep cavities, such as molds for processing cup-shaped plastic parts, existing cleaning methods are inadequate. Due to the greater cavity depth, manual brushes cannot reach the deep parts of the cavity, resulting in impurities accumulated there not being effectively removed. This incomplete cleaning will cause quality problems in the corresponding locations deep within the cavity in the subsequently produced plastic parts.

[0003] Therefore, it is necessary to provide a new structure for cleaning the surface of plastic mold cavities to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cleaning structure for the surface of a plastic mold cavity.

[0005] The plastic mold cavity surface cleaning structure provided by this utility model includes: an injection molding machine body, a mounting box, a cleaning brush, a drive assembly, and a flow guide. The injection mold is symmetrically installed inside the injection molding machine body. The mounting box is installed inside the injection molding machine body. Spiral cleaning brushes are equidistantly installed inside the mounting box. The outer wall of the cleaning brush is provided with wear-resistant bristles. The drive assembly is installed between the mounting box and the cleaning brush. The drive assembly drives the cleaning brush to rotate and clean the impurities inside the injection mold cavity. A flow guide for collecting impurities is installed at the bottom of the mounting box.

[0006] Preferably, the drive assembly includes a motor, a drive gear, and a driven gear. The motor is fixedly connected to the top of the mounting box, and the drive gear is fixedly connected to the output end of the motor. Atomizing tubes are fixedly connected at equal intervals inside the mounting box. The cleaning brushes are all sleeved on the outer wall of the corresponding atomizing tube and fixedly connected to their outer walls. A driven gear is fixedly connected to the end of the atomizing tube away from the cleaning brush, and all of the driven gears are in a meshing state. The drive gear meshes with one of the driven gears closest to the motor.

[0007] Preferably, the installation box has a delivery pipe fixedly connected inside, and the end of the atomizing tube near the driven gear is connected to the delivery pipe and rotatably connected to the delivery pipe through a connector.

[0008] Preferably, a vacuum cleaner is installed inside the injection molding machine body, and the input end of the vacuum cleaner is connected to a retractable hose, the other end of which is connected to the bottom of the flow guide.

[0009] Preferably, the injection molding machine body is internally fixedly connected to a slide rail, the top of the slide rail is slidably connected to a movable frame, and the top of the slide rail is fixedly connected to an electric push rod, the output end of which is fixedly connected to the side wall of the movable frame.

[0010] Preferably, the movable frame is internally fixedly connected to an electric actuator two, and the output end of the electric actuator two is fixedly connected to the side wall of the mounting box.

[0011] Preferably, a liquid storage tank is fixedly connected to the top of the mobile frame, a water pump is installed on the top of the liquid storage tank, and the input end of the water pump is connected to the liquid storage tank through a connecting pipe, and the output end of the water pump is connected to the delivery pipe through a flexible hose.

[0012] Compared with related technologies, the plastic mold cavity surface cleaning structure provided by this utility model has the following beneficial effects: The electric actuator drives the cleaning brush deep into the cavity. Combined with the high-speed rotation of the spiral cleaning brush, it can reach the depths of the cavity and thoroughly wipe the inner wall. The wear-resistant bristles can effectively remove accumulated impurities. With the wetting and dissolving effect of the cleaning liquid, it can thoroughly remove deep impurities that are difficult to reach by manual cleaning, avoiding quality problems of subsequent plastic parts due to incomplete cleaning. Impurities generated during the cleaning process are collected by a flow guide and quickly removed by a vacuum cleaner, preventing them from falling into the injection molding machine or the production environment, reducing pollution to the production environment, helping to maintain the cleanliness and hygiene of the workshop, and meeting the environmental protection requirements of modern production. The entire cleaning process requires no manual intervention. From aligning the electric push rod two and driving the cleaning brush with the electric push rod one, to the water pump delivering cleaning fluid, the motor driving the cleaning brush to rotate, and then the vacuum cleaner removing impurities and resetting all components, everything is completed automatically through the mechanical structure. This not only eliminates the tedious steps of manual operation and greatly improves cleaning efficiency, but also avoids the problem of unstable cleaning results caused by differences in force and angle during manual cleaning, ensuring that every cleaning achieves a consistent high-quality standard.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figures 1 to 4 A surface cleaning structure for a plastic mold cavity is disclosed. The structure includes: an injection molding machine body 1, a mounting box 3, a cleaning brush 4, a drive assembly, and a flow guide 5. An injection mold 2 is symmetrically mounted inside the injection molding machine body 1. The mounting box 3 is also installed inside the injection molding machine body 1. Spiral cleaning brushes 4 are equidistantly mounted inside the mounting box 3. The outer wall of the cleaning brushes 4 is provided with wear-resistant bristles. A drive assembly is installed between the mounting box 3 and the cleaning brushes 4. The drive assembly drives the cleaning brushes 4 to rotate and clean impurities from inside the cavity of the injection mold 2. A flow guide 5 for collecting impurities is installed at the bottom of the mounting box 3. The drive assembly includes: a motor 6, a drive gear 7, and a driven gear 8. The motor 6 is fixedly connected to the top of the mounting box 3. The output end of 6 is fixedly connected to a drive gear 7. The interior of the mounting box 3 is fixedly connected to atomizing tubes 9 at equal intervals. The cleaning brushes 4 are all sleeved on the outer wall of the corresponding atomizing tubes 9 and fixedly connected to their outer walls. The end of the atomizing tube 9 away from the cleaning brush 4 is fixedly connected to a driven gear 8, and several of the driven gears 8 are in a meshing state. The drive gear 7 meshes with one of the driven gears 8 closest to the motor 6. The interior of the mounting box 3 is fixedly connected to a conveying pipe 10. The end of the atomizing tube 9 close to the driven gear 8 is connected to the conveying pipe 10 and is rotatably connected to the conveying pipe 10 through a connector. The interior of the injection molding machine body 1 is equipped with a vacuum cleaner 11. The input end of the vacuum cleaner 11 is connected to a retractable hose, and the other end of the hose is connected to the bottom of the guide cover 5.

[0018] It should be noted that: the motor 6 is an existing mature device; the installation direction of the spiral cleaning brush 4 is consistent with the rotation direction of the corresponding atomizing tube 9, ensuring that when the motor 6 starts, the atomizing tube 9 is driven to rotate through the transmission of the active gear 7 and the driven gear 8, so that the spiral cleaning brush 4 can brush out the impurities inside the cavity.

[0019] Please see Figure 3 and Figure 4 The injection molding machine body 1 is internally fixedly connected to a slide rail 12. A movable frame 13 is slidably connected to the top of the slide rail 12. An electric push rod 14 is fixedly connected to the top of the slide rail 12, and its output end is fixedly connected to the side wall of the movable frame 13. An electric push rod 15 is fixedly connected to the inside of the movable frame 13. The output end of the electric push rod 15 is fixedly connected to the side wall of the mounting box 3. A liquid storage tank 16 is fixedly connected to the top of the movable frame 13. A water pump 17 is installed on the top of the liquid storage tank 16. The input end of the water pump 17 is connected to the liquid storage tank 16 through a connecting pipe. The output end of the water pump 17 is connected to the delivery pipe 10 through a hose. It should be noted that both electric actuator 14 and electric actuator 2 15 are existing mature equipment. When cleaning is required, electric actuator 2 15 is activated first to push the mounting box 3 to align with the injection mold 2. Then, electric actuator 14 is activated to push the moving frame 13, which in turn drives the mounting box 3 and the cleaning brush 4 inside it into the cavity. After cleaning, electric actuator 14 is activated, which drives the moving frame 13, the mounting box 3, and the cleaning brush 4 out of the cavity. Then, electric actuator 2 15 is activated, which drives the mounting box 3 to reset.

[0020] The working principle of the plastic mold cavity surface cleaning structure provided by this utility model is as follows: When it is necessary to clean the cavity of the injection mold 2, first ensure that the injection molding machine body 1 is stopped and the injection mold 2 is separated to provide sufficient space for the cleaning operation. At this time, the electric push rod 15 installed inside the moving frame 13 starts first. Since its output end is fixedly connected to the side wall of the mounting box 3, the mounting box 3 will move with the extension and retraction of the output end of the electric push rod 15 until the position of the mounting box 3 and the injection mold 2 are completely aligned. Then the electric push rod 15 stops running, completing the initial alignment of the cleaning position. Next, the electric actuator 14, which is fixed on the top of the slide rail 12 inside the injection molding machine body 1, is activated. Its output end is fixedly connected to the moving frame 13, which will push the moving frame 13 and the mounting box 3 associated with the moving frame 13 to move synchronously along the slide rail 12. During this process, the cleaning brush 4 inside the mounting box 3 gradually extends into the cavity of the injection mold 2 to prepare for deep cleaning. At the same time, the water pump 17 of the liquid storage tank 16 on the top of the moving frame 13 is activated, which delivers the cleaning liquid in the liquid storage tank 16 to the delivery pipe 10 through the hose. Then, through the atomizing pipe 9 nozzle connected to the delivery pipe 10, the cleaning liquid is converted into a uniform water mist and sprayed on the inner wall of the cavity. With the help of the wetting and dissolving effect of the cleaning liquid, favorable conditions are created for subsequent impurity cleaning. When the cleaning brush 4 moves with the mounting box 3 to the depth of the cavity and fits against the inner wall, the electric actuator 14 stops running; then, the motor 6 starts, and the driving gear 7 fixed at its output end meshes with a driven gear 8 close to the motor 6, while several driven gears 8 mesh with each other. This gear transmission structure drives all atomizing tubes 9 to rotate synchronously; since the cleaning brush 4 is spiral and fixed to the outer wall of the atomizing tube 9, the rotation of the atomizing tube 9 will drive the cleaning brush 4 to rotate rapidly, using the wear-resistant bristles to thoroughly wipe the inner wall of the cavity and completely clean away the accumulated impurities; The impurities generated during cleaning will fall into the guide hood 5 at the bottom of the mounting box 3. The guide hood 5 is connected to the input end of the vacuum cleaner 11 through a retractable hose. At this time, the vacuum cleaner 11 starts synchronously and quickly sucks away the impurities collected in the guide hood 5 through negative pressure to avoid impurity residue or secondary pollution. After the cleaning work is completed, the motor 6 is turned off and the cleaning brush 4 stops rotating; the electric push rod 14 retracts, driving the moving frame 13 to move in the opposite direction and reset along the slide rail 12, and the mounting box 3 moves in the opposite direction, so that the cleaning brush 4 is disengaged from the cavity; then the electric push rod 2 15 is started, driving the mounting box 3 back to the initial position, and the entire cleaning system returns to the standby state, waiting for the next cleaning instruction.
