[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Embodiment 1
[0020] See also Figure 1-2 , a nozzle cleaning mechanism for an injection molding machine, a water storage chamber 2 is provided at the lower part of the inner wall of a casing 1, a motor 3 is fixedly installed at the upper part of the inner wall of the casing 1, a gear 1 4 is fixedly installed at the output shaft of the motor 3, a water suction pipe 5 is plugged at the top side of the water storage chamber 2, a water pump 16 is arranged at the upper part of the water suction pipe 5, the water pump 16 is fixedly installed at the top side of the water storage chamber 2, a sealing ring 8 is rotatably connected to the side of the casing 1, a gear 2 6 is fixedly installed at one side of the sealing ring 8 inside the casing 1, the gear 1 4 is meshed with the gear 2 6, the number of nozzles 11 is multiple and they are arranged in a circular array outside the insertion tube 10, the inner wall of the nozzle can be effectively cleaned through the mutual cooperation between the brush 12 and the nozzle 11, an insert pipe 7 is embedded in the gear 2 6, the insert pipe 7 is rotatably connected to the end of the water suction pipe 5 away from the water storage chamber 2, and the sealing ring 8 is away from the end of the casing 1. An insertion tube 10 is fixedly installed on the side, a nozzle 11 is fixedly installed on the outside of the insertion tube 10, and a brush 12 is fixedly installed on the outside of the insertion tube 10. The brush 12 is made of nylon, and the length of the brush 12 on one side close to the casing 1 is smaller than the length on the other side. The brush 12 is relatively soft and its shape fits the inner wall of the nozzle more closely. The insertion tube 7 is connected to the insertion tube 10, and an anti-skid pad 15 is glued to the side of the casing 1. The sealing ring 8 and the insertion tube 10 are both located in the middle of the side of the casing 1. The anti-skid pad 15 can be convenient for the staff to hold. The utility model drives the brush 12 into the nozzle of the injection molding machine through the insertion tube 10, and the insertion tube 10 drives the brush 12 to rotate on the inner wall of the nozzle. The cleaning liquid is sprayed outward through the nozzle 11, so that the inner wall of the nozzle is cleaned more thoroughly, and the residual part of the inner wall of the nozzle is scraped off.
[0021] When in use, fill the water storage chamber 2 with cleaning liquid, start the water pump 16 so that the cleaning liquid enters the insertion tube 7 through the suction pipe 5, and the user holds the anti-slip pad 15 to insert the insertion tube 10 into the injection molding machine nozzle. The insertion tube 10 drives the brush 12 to enter the injection molding machine nozzle. The brush 12 is relatively soft and contacts the inner wall of the nozzle after being squeezed by the nozzle. The motor 3 is started, and the output shaft of the motor 3 drives the gear 1 4 to rotate. When the gear 1 4 rotates, it drives the gear 2 6 to rotate. The gear 2 6 drives the insertion tube 10 to rotate. The insertion tube 10 drives the brush 12 to rotate on the inner wall of the nozzle. Because the lengths of the two ends of the brush 12 are inconsistent and fit the shape of the inner wall of the nozzle more closely, the cleaning liquid is sprayed outward through the nozzle 11. At the same time, the nozzle 11 performs a circular motion with the insertion tube 10 as the axis, and cooperates with the rotation of the brush 12 to make the inner wall of the nozzle be cleaned more thoroughly, and the residual part of the adhesion to the inner wall of the nozzle is scraped off.
[0022] Embodiment 2
[0023] See also Figure 3-4On the basis of the first embodiment, a plurality of fixing grooves 14 are provided on the side of the insertion tube 10, and the fixing grooves 14 are slidably connected with anti-dropping clamps 13, and a sliding sleeve 9 is slidably sleeved on the outside of the insertion tube 10, and the sliding sleeve 9 contacts the anti-dropping clamps 13. The anti-dropping clamps 13 pop out after being connected to the nozzle of the injection molding machine and clamp the inner wall of the nozzle. The side of the anti-dropping clamps 13 close to the sealing ring 8 is an inclined surface, and a plurality of springs are arranged between the anti-dropping clamps 13 and the fixing grooves 14. The anti-dropping clamps 13 can be retracted into the fixing grooves 14 by sliding the sliding sleeve 9. The utility model clamps the nozzle mouth by the anti-dropping clamps 13, and then the insertion tube 10 rotates to prevent the insertion tube 10 from being separated from the nozzle during the cleaning process, so that the cleaning process is more stable.
[0024] During use, on the basis of Example 1, when the insertion tube 10 is inserted into the nozzle of the injection molding machine, the anti-slip clamp 13 shrinks into the fixed groove 14 under the pressure of the nozzle. After the anti-slip clamp 13 enters the nozzle, because the nozzle is conical, the space of the anti-slip clamp 13 in the nozzle becomes larger, so that the anti-slip clamp 13 automatically pops out under the elastic force of the spring, and the anti-slip clamp 13 clamps the nozzle mouth. Then the insertion tube 10 rotates to prevent the insertion tube 10 from being separated from the nozzle during cleaning. When the nozzle needs to be removed, the sleeve 9 is slid away from the casing 1, and the sleeve 9 slides forward along one side of the anti-slip clamp 13. The sleeve 9 drives the anti-slip clamp 13 to be retracted into the fixed groove 14 through the interaction force between the inclined surfaces. At this time, the anti-slip clamp 13 is no longer in contact with the nozzle, so that the insertion tube 10 can be pulled out.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
