Description

A cleaning device for injection nozzles of injection molding machines Technical Field

[0001] This utility model relates to the field of injection nozzle residue cleaning technology, and more specifically to an injection nozzle cleaning device for injection molding machines. Background Technology

[0002] The injection nozzle is a key component of an injection molding machine. Its main function is to inject molten plastic into the mold through the nozzle to form the desired molded product shape. The injection nozzle achieves injection molding by controlling the flow speed and direction of the plastic, and can adjust parameters such as filling speed, pressure, and temperature to ensure stable quality of the molded product.

[0003] A search revealed a Chinese patent for a device for cleaning residual material from an injection molding machine nozzle (authorization announcement number CN221232993U), which falls under the technical field of "injection nozzle residual material cleaning." The protected claim includes: "a distribution box; a partition is provided inside the distribution box; the partition divides the distribution box into a first cavity and a second cavity; one side of the distribution box is connected to a water pipe via a first connection port, and a second connection port at the bottom is connected to a water tank; one side of the first cavity is connected to an injection molding connecting pipe; the other end of the injection molding connecting pipe is connected to the injection nozzle; one end of the injection nozzle is fixedly connected to the water tank. During use, when the mixing hopper is placed in the placement port of the placement plate, injection molding material is added to the mixing hopper, thereby transferring the material to be injected through the first cavity in the distribution box to the injection molding connecting pipe. The other end of the injection molding connecting pipe is connected to the injection nozzle, thus effectively realizing the injection operation of the injection nozzle."

[0004] The shortcomings of the existing technology are as follows: In the above-mentioned equipment, pressure is generated by driving the electric cylinder to make piston movement, which effectively flushes the residual material inside the injection nozzle with water from the water tank. However, it cannot clean the residual material adhering to the outside of the injection nozzle, which may cause the injection nozzle to be blocked. At the same time, the uncleaned residual material may be mixed with new plastic particles in the next injection process, which will further lead to insufficient plasticization, affect the quality of the product, reduce the practicality of the equipment, and be detrimental to actual application and operation.

A flap 25 is rotatably connected to one side of the inner wall of the second cavity 24. An electric telescopic rod 26 is rotatably connected to one side of the second cavity 24 and located below the flap 25. The piston rod of the electric telescopic rod 26 is rotatably connected to the bottom of the flap 25, disengaging the injection nozzle 14 from the inside of the molding groove 29, causing one end of the injection nozzle 14 to move into the inside of the first cavity 16. Then, the lead screw 18 is manually rotated, in conjunction with the auxiliary rod 17, to move the L-shaped plate 19 downwards inside the first cavity 16, causing one side of the L-shaped plate 19 to block the molding groove. At the slot of 29, the drive motor 20 drives one of the rotating shafts 21 to rotate, and at the same time drives one of the pulleys 22 to rotate. In conjunction with the belt, it drives the pulley 22 on the other rotating shaft 21 to rotate, and at the same time drives the brushes 23 on both rotating shafts 21 to rotate, thereby cleaning the residual material on the injection nozzle 14. Then, the electric telescopic rod 26 is driven to drive the flap 25 to flip the top of the second cavity 24, so that water and residual material are discharged through the inside of the second cavity 24 into the fourth cavity 28 below the third cavity 27, completing the collection of residual material and preventing additional cleaning work for the staff.

The solidified model is dropped into the collection box 41 through the square groove 39 to complete the collection function.

[0030] The working principle of this utility model is as follows: First, the second cylinder 34 is driven to move the left mold plate 36 inside the second plate 35 to the right mold groove 37. Then, one end of the injection nozzle 14 is inserted from the inside of the first cavity 16 into the inside of the molding groove 29. With the help of the sealing ring 30, the molding groove 29 and the outer side of one end of the injection nozzle 14 are sealed. At the same time, the through pipe 32 is inserted into the inside of the injection nozzle 14, and the liquid material is added into the inside of the material tank 9 through the hopper 13. Then, the first cylinder 10 is driven to drive the piston plate 11 on the piston rod of the first cylinder 10 to slide back and forth inside the material tank 9, adding the liquid material into the through pipe 32 through the injection nozzle 14. The material is injected into the right mold groove 37 through the pipe 32, and then the recondenser 38 is driven to condense and solidify the liquid in the right mold groove 37, completing the molding operation. The second cylinder 34 is driven again to separate the second platen 35 from the first platen 31, and the solidified mold is dropped into the collection box 41 through the square groove 39 for collection. After the molding operation is completed, the T-shaped rod 6 is manually pulled to move the slider 4 at the bottom of the slide plate 2 into the slide groove 3, causing the spring 5 to deform. Then the baffle 7 is rotated ninety degrees on the T-shaped rod 6 to complete the limit operation, and at the same time the injection nozzle 14 exits from the injection groove 29. The internal components are disengaged, causing one end of the injection nozzle 14 to move into the first cavity 16. Water is then added into the material tank 9 through the hopper 13. The first cylinder 10 is then driven, causing the piston plate 11 to slide back and forth inside the material tank 9, discharging the water through the injection nozzle 14 into the first cavity 16, thus cleaning the inside of the injection nozzle 14. Then, the lead screw 18 is manually rotated, in conjunction with the auxiliary rod 17, to move the L-shaped plate 19 downward inside the first cavity 16, so that one side of the L-shaped plate 19 blocks the opening of the molding groove 29. Then, the motor 20 is driven, causing one of the rotating shafts 21 to rotate, while simultaneously driving one of the belts. Wheel 22 rotates, and in conjunction with the belt, drives the pulley 22 on another shaft 21 to rotate. Simultaneously, the brushes 23 on both shafts 21 rotate, and with the help of water, they brush the outside of the injection nozzle 14, cleaning the residual material on the injection nozzle 14. Then, the electric telescopic rod 26 is driven to flip the flap 25 at the top of the second cavity 24, so that water and residual material are discharged through the inside of the second cavity 24 into the fourth cavity 28 below the third cavity 27, completing the collection of residual material. This prevents additional cleaning work for personnel, increases the practicality of the equipment, and is beneficial for practical application and operation.
