[0002] As an important component of automotive air conditioning and ventilation systems, the molding quality of automotive ducts directly affects the vehicle's performance and comfort. Automotive ducts are typically formed through injection molding or stamping using molds. During the long-term production process, plastic debris, oil, dust, and other contaminants can remain inside the mold cavity.

[0003] A Chinese patent number CN223000914U describes an automotive duct forming mold. This utility model, by setting an installation part, allows the end mold to be installed on the top and bottom of mold one and mold two via a snap-fit ​​long plate. The frame is then placed close to the sides of mold one and mold two, and the snap-fit ​​plate passes through the end buckle. Subsequently, pressing the switch activates telescopic rod one, causing the long plate to retract into the frame, moving the snap-fit ​​plate and completing the snap-fit ​​between the snap-fit ​​plate and the end buckle. This completes the secure installation of the end mold, achieving the effect of convenient installation and disassembly of the end mold.

[0004] While high-pressure water jet cleaning can wash away some contaminants on the mold surface, it has limited effectiveness in cleaning stubborn oil stains and debris attached to crevices. Utility Model Content

[0013] This utility model provides a cleaning device for automotive air duct forming molds, which has the following advantages compared with the prior art: This design discloses a cleaning device for automotive duct forming molds. When cleaning the molds, the movable door is first closed to seal the forming machine and prevent water splashing outside. Then, the controller activates a second servo motor to drive one of the lead screws, which in turn drives two lead screws to rotate synchronously in opposite directions via two gears. This drives the two molds to move in opposite directions and open. At this point, an electric slide rail drives a slider to move an electric push rod horizontally. Simultaneously, the first servo motor activates to drive the electric push rod to rotate, which in turn drives a water tank at the bottom to rotate synchronously. The two molds are then adjusted to contact the brush. As the water tank rotates, it drives the brush to rotate, cleaning the mold surface. Simultaneously, a suction pump is activated to deliver water to the water tank through a delivery pipe, which is then sprayed out through nozzles. This achieves simultaneous water washing and brush cleaning, effectively removing stubborn oil stains and debris adhering to crevices. Wastewater from the cleaning process flows into a groove and is discharged from the drain. After cleaning, the brush can be moved to the rear end of the forming machine without affecting the subsequent use of the molds, achieving the desired cleaning effect for stubborn oil stains and debris adhering to crevices on the molds.

[0017] Please see Figures 1-4 This utility model provides a technical solution for a cleaning device for automotive duct forming molds: It includes a forming machine 1, with a groove 2 at the bottom and a drain outlet 11 at the bottom side of the groove 2. Two molds 3 are installed inside the groove 2. A sliding opening is provided at the top of the forming machine 1, and an electric slide rail 7 is embedded within the sliding opening. A first servo motor 9 is slidably connected to the electric slide rail 7 via a slider 8. An electric push rod 6 is rotatably connected to the bottom of the slider 8, and the output end of the first servo motor 9 is connected to the electric push rod 6. The movable end of the 6 is rotatably connected to a connector 12, and the bottom end of the connector 12 is rotatably connected to a water storage tank 16. A brush 13 is fitted on the surface of the water storage tank 16, and multiple spray holes 15 are equidistantly opened on the surface of the water storage tank 16. A round hole 17 that coincides with the spray hole 15 is opened on the brush 13. A water injection hole 14 that communicates with the inside of the water storage tank 16 is opened on the side end of the connector 12. A conveying pipe 10 extending to the outside of the molding machine 1 is threadedly connected to the water injection hole 14, and the end of the conveying pipe 10 away from the water injection hole 14 is connected to a water tank through a suction pump. A controller is fixedly connected to the molding machine 1 to control the first servo motor 9, the electric push rod 6, the suction pump, and the second servo motor 19.

[0018] Please see Figure 1A guide rail 5 is fixedly connected to the lower front end of the molding machine 1. A transparent movable door 4 is slidably connected inside the guide rail 5, and the upper part of the movable door 4 is slidably connected to the side end of the molding machine 1. A lead screw 20 is symmetrically rotatably connected to the inner wall of the groove 2, and two molds 3 are respectively threaded to the two lead screws 20 through connecting blocks. Gears 21 are sleeved on the surface of the two lead screws 20 located outside the molding machine 1, and the two gears 21 are meshed. A support plate is fixedly connected to the side end of the molding machine 1, and a second servo motor 19 is fixedly connected to the support plate. The output end of the second servo motor 19 is connected to one of the lead screws 20.

[0019] Please see Figure 2 and Figure 4 The inner wall of the brush 13 is fixedly connected to the surface of the water tank 16 at equal intervals with multiple corresponding Velcro straps, and two corresponding Velcro straps are bonded together. The distance between the mold 3 and the rear end of the forming machine 1 is greater than the outer diameter of the brush 13.

[0020] The working principle of this utility model is as follows: When cleaning the mold 3, first close the movable door 4 to seal the molding machine 1 and prevent water from splashing out later. Then, the controller starts the second servo motor 19 to drive one of the lead screws 20, and through the two gears 21, drives the two lead screws 20 to rotate synchronously in opposite directions, thereby driving the two molds 3 to move in opposite directions and open. At this time, the electric slide rail 7 can be activated to drive the slider 8 to move the electric push rod 6 horizontally. At the same time, the first servo motor 9 is activated to drive the electric push rod 6 to rotate. The electric push rod 6 drives the water tank 16 at the bottom to rotate synchronously. At this time, the two molds 3 are adjusted to contact the brush 13. As the water tank 16 rotates, it drives the brush 13 to rotate to clean the surface of the molds 3. While cleaning, the suction pump is turned on to deliver water to the water storage tank 16 through the delivery pipe 10, and then spray it out through the spray hole 15. This achieves the effect of washing with water while brushing with the brush 13, cleaning away stubborn oil stains and debris attached to the crevices. The wastewater generated during cleaning flows into the groove 2 and is discharged from the drain outlet 11. After cleaning, the brush 13 can be moved to the rear end of the molding machine 1. Since the distance between the mold 3 and the rear end of the molding machine 1 is greater than the outer diameter of the brush 13, the brush 13 will not affect the subsequent use of the mold 3 when it stays here. When the brush 13 is used for a long time, the Velcro can be removed to clean and replace the brush 13. Through the above cleaning mechanism, the stubborn oil stains and debris attached to the crevices on the mold 3 can be cleaned.
