Description

Technical Field

[0001] This utility model relates to the field of internal cavity cleaning technology, and in particular to an internal cavity cleaning device for injection molding machinery. Background Technology

[0002] In modern manufacturing, injection molding machines, as core equipment for plastic processing, are widely used in many fields such as automobiles, electronics, medical devices, and daily necessities. Their working principle involves injecting molten plastic raw materials into a mold cavity of a specific shape, which then cools and solidifies to obtain the desired plastic product.

[0003] However, during long-term production, the inner cavity of injection molding machines easily accumulates residual plastic melt, additive residues, and scorched materials generated at high temperatures. If these residues are not removed promptly and thoroughly, they can cause a series of problems: Firstly, these residues may mix into the plastic raw materials used in subsequent production, leading to defects such as black spots, streaks, and bubbles in the finished products, severely affecting product quality and yield, and increasing production costs. Secondly, long-term accumulation of residues can exacerbate wear between the screw and the barrel, shortening the equipment's lifespan, and may also affect the plasticizing effect and conveying stability of the material, reducing production efficiency.

[0004] Current cleaning methods mostly involve manual cleaning by holding a brush in one hand and rinsing with water in the other. This is inconvenient, and the two-handed operation results in insufficient rinsing force, which is not effective in removing stubborn deposits. Furthermore, it does not allow for timely drying.

[0008] The technical effects achieved by adopting the above solution are: heating the rinsing water flow to improve the effect of dissolving stains, allowing the wastewater to be discharged quickly after cleaning, and drying the surface after cleaning.

[0009] Preferably, in any of the above embodiments, the width of the fixed plate is smaller than the diameter of the inner wall of the drying air duct, a connecting bearing is fixedly connected to the center of the fixed plate, the outer wall of the rotating tube is fixedly connected to the inner ring of the connecting bearing, and the rotating tube is rotatably connected to the fixed plate through the connecting bearing.

[0010] The technical effects achieved by adopting the above solution are: reducing the obstruction of airflow by the fixed plate, and at the same time, the connection of the bearing can reduce rotational friction and improve rotational stability.

[0011] Preferably, of any of the above embodiments, an operating handle is fixedly connected to the top of one end of the outer wall of the drying air duct, and a lifting handle is fixedly connected to the middle of the outer wall of the drying air duct on the side away from the operating handle.

[0012] The technical effect achieved by adopting the above solution is that it facilitates the lifting operation with both hands, both forward and backward, by operating the handle and the pull handle.

[0013] Preferably, in any of the above embodiments, the diameter of the driven bevel gear is smaller than the diameter of the inner wall of the drying air duct, one end of the cylindrical nozzle has a spherical structure, and the nozzle orifice of the cylindrical nozzle is located between several bristles.

[0014] The technical effect achieved by adopting the above solution is that the rinsing water can be sprayed out between several bristles, and the end of the spherical structure facilitates contact with the inside of the cavity, reducing friction.

[0015] This utility model has the following advantages: 1. The internal cleaning device of this injection molding machine is connected to an external water source through a water inlet valve, and then water is supplied to the rotating pipe through a connecting elbow. The water flow is then output outward through a cylindrical nozzle. At the same time, the drive motor drives the drive gear to rotate, which in turn drives the driven bevel gear to rotate, causing the rotating pipe to rotate. This, in turn, drives the cylindrical nozzle to rotate at high speed, causing several brush bristles to rotate and clean the internal cavity of the injection molding machine. This allows rinsing and brushing to be carried out simultaneously, enabling two-handed operation of the cylindrical nozzle and brush bristles to clean at the same time, resulting in greater cleaning force.

It can also dry the surface after cleaning, improving the cleaning efficiency. Attached Figure Description

[0021] As an optional technical solution of this utility model: a blower nozzle 2 is fixedly connected to one end of the drying air duct 1 near the cylindrical nozzle 5. The cylindrical nozzle 5 and several bristles 6 are located outside the blower nozzle 2. The center of the cylindrical nozzle 5 and the blower nozzle 2 are corresponding. The airflow is blown through the drying air duct 1 and the blower nozzle 2 toward the cleaning position of the cylindrical nozzle 5 and the bristles 6, so that the rinsing water is heated, which improves the effect of dissolving stains. At the same time, the wastewater after cleaning is quickly discharged, and the surface can be dried after cleaning.

[0022] As an optional technical solution of this utility model: the width of the fixed plate 12 is smaller than the diameter of the inner wall of the drying air duct 1, a connecting bearing is fixedly connected at the center of the fixed plate 12, the outer wall of the rotating tube 13 is fixedly connected to the inner ring of the connecting bearing, and the rotating tube 13 is rotatably connected to the fixed plate 12 through the connecting bearing, thereby reducing the obstruction effect of the fixed plate 12 on the airflow.

[0026] In summary, this utility model connects to an external water source via an inlet valve 4, then supplies water to a rotating pipe 13 via a connecting elbow 10, and outputs a flushing water flow through a cylindrical nozzle 5. Simultaneously, a drive motor 8 drives a drive gear 14 to rotate, which in turn drives a driven bevel gear 15 to rotate, causing the rotating pipe 13 to rotate. This, in turn, drives the cylindrical nozzle 5 to rotate at high speed, causing several brush bristles 6 to rotate and clean the inner cavity of the injection molding machine. This allows for simultaneous flushing and brushing, enabling two-handed operation of the cylindrical nozzle 5 and brush bristles 6 for simultaneous cleaning, resulting in greater cleaning force. Combined with the high-speed rotation, this enhances the cleaning effect. A hot air blower 3 outputs high-temperature airflow to the drying duct 1, which then blows through the drying duct 1 and the blower nozzle 2 onto the cleaning positions of the cylindrical nozzle 5 and brush bristles 6. This heats the flushing water, improving the dissolution of stains, while also allowing for rapid discharge of wastewater after cleaning. Furthermore, the surface can be dried after cleaning, further improving cleaning efficiency.
