Description

Technical Field

[0001] This utility model relates to the technical field of mold cleaning, and specifically relates to an injection mold cleaning device. Background Art

[0002] An injection mold cleaning device is a special equipment used to remove residual plastics, dirt, carbon deposits and other impurities inside the mold during the injection production process. In injection production, the mold is a key tool for producing plastic products, and the cleanliness of its surface directly affects the quality and production efficiency of plastic products.

[0003] However, when we actually use it, after spraying the heated material into the injection mold for press-fitting and shaping, after long-term use, various stains will adhere to the injection mold, which will cause the subsequent press-fitted material to be incomplete. Therefore, it is necessary to clean the injection mold that has been used for a long time. There are various cleaning methods. Usually, a spray head is used to clean the stains on the injection mold with water. However, the existing injection mold is provided with multiple holes for press-fitting, and its interior often adheres to residual materials. After the residual materials solidify, they are extremely hard. Therefore, it becomes difficult to clean them by using the spray head method, and it is necessary to use a scraper again to remove them, which will lead to low cleaning efficiency. For this reason, we propose an injection mold cleaning device. Summary of the Utility Model

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1

[0030] Please refer to Figures 1-6 , the present utility model provides a technical solution:

[0031] An injection mold cleaning device includes a handle 1, a spray pipe 2 provided on the side of the handle 1, and a rotating tube 12 movably sleeved on the spray pipe 2, and further includes:

[0032] A rotating cylinder 6, the inner wall of the rotating cylinder 6 is sleeved on the rotating tube 12 and is communicated with the spray pipe 2;

[0033] The inclined plates 5 are disposed on the inner wall of the rotating cylinder 6. There are multiple inclined plates 5, and the inclined plates 5 are also arc-shaped and can rotate along with the water flow, thereby driving the rotation of the rotating cylinder 6;

[0034] The scraping blade 3 is disposed on the rotating pipe 12 and is used for scraping the residual material in the mold;

[0035] The switching component 4 is disposed on the spray pipe 2 and is used to drive the scraping blade 3 to rotate through the inclined plates 5 and the rotating cylinder 6, and at the same time, the up and down movement of the scraping blade 3 can be switched.

[0036] The switching component 4 includes a limiting ring 42 sleeved on the rotating pipe 12. The end face of the limiting ring 42 is disposed at one end of the rotating cylinder 6. A cam 41 is sleeved on the rotating pipe 12. A clamping groove 43 is formed on the end face of the cam 41 away from the rotating cylinder 6. A clamping block 46 is disposed on the side surface of the scraping blade 3, and the clamping block 46 is movably disposed inside the clamping groove 43. When the cam 41 rotates the scraping blade 3, the clamping block 46 disposed on the side surface of the scraping blade 3 can be connected to the inside of the clamping groove 43. When the scraping blade 3 needs to move up and down, the clamping block 46 needs to be connected to the groove inside the cam 41, and the up and down movement effect is achieved by rotating the cam 41.

[0037] A guide rod 45 is disposed on the end face of the limiting ring 42. A guide groove 47 is formed on the end face of the cam 41. The guide rod 45 is movably disposed on the inner wall of the guide groove 47. A first spring 44 is sleeved on the outer surface of the guide rod 45. The two ends of the first spring 44 are respectively disposed on the end faces of the limiting ring 42 and the cam 41. An opening and closing component 7 for switching the up and down movement of the scraping blade 3 is disposed on the outer surface of the rotating pipe 12. The first spring 44 can drive the cam 41 to reset, so that when it rotates, the displacement distance can be reduced, thereby causing the clamping block 46 to fall off from the inside of the clamping groove 43.

[0038] The opening and closing component 7 includes a fixed ring 71 disposed on the spray pipe 2. A moving ring 77 is movably sleeved on the outer surface of the spray pipe 2. A second spring 72 is sleeved on the outer surface of the spray pipe 2. The two ends of the second spring 72 are respectively disposed on the end faces of the fixed ring 71 and the moving ring 77. The second spring 72 can connect the moving ring 77 and the scraping blade 3.

[0039] A through groove 76 is formed on the end face of the moving ring 77. A slider 74 is disposed on the outer surface of the spray pipe 2. The slider 74 is movably disposed on the inner wall of the through groove 76. A lifting block 73 is disposed on the side surface of the scraping blade 3. A straight groove 75 is formed on the end face of the moving ring 77. The lifting block 73 is movably disposed on the inner wall of the straight groove 75. The disposed slider 74 can not only play a guiding role for the moving ring 77, but also play a limiting role for the moving ring 77 when the scraping blade 3 rotates.

[0040] A fixed shell 8 is provided on the outer surface of the rotating pipe 12. A scraper 3 is movably arranged inside the fixed shell 8. A tension spring 9 is arranged between the fixed shell 8 and the scraper 3. The two ends of the tension spring 9 are respectively arranged at the bottom of the scraper 3 and the inner wall of the fixed shell 8. The arrangement of the tension spring 9 can be reset when the scraper 3 moves up and down, so as to achieve the up and down movement effect.

[0041] When using this device, first, water needs to be conveyed into the spray pipe 2 through the handle 1, and the inside of the injection mold can be cleaned. When encountering residual materials that are difficult to clean, it is necessary to rotate the multiple inclined plates 5 arranged inside the spray pipe 2 through the water flow. The rotation of the inclined plates 5 can drive the rotating cylinder 6 to rotate. The rotation of the rotating cylinder 6 drives the rotating pipe 12 arranged at the end face to rotate. The rotating pipe 12 drives the cam 41 arranged on the outer surface to rotate. The cam 41 drives the multiple clamping blocks 46 arranged inside to rotate. Thus, the clamping blocks 46 drive the scraper 3 arranged on the side to rotate, so as to clean the inside of the hole groove. When it is necessary to stop the rotation of the scraper 3, it is necessary to slide the through groove 76 opened at the end face of the moving ring 77 on the outer surface of the slider 74, so that the straight groove 75 arranged at the end face of the moving ring 77 is stuck on the lifting block 73 arranged on the side of the scraper 3, so that the scraper 3 stops rotating. When it is necessary to move the scraper 3 up and down, pull the cam 41 to squeeze the first spring 44. At this time, the clamping block 46 in the clamping groove 43 falls off, and the clamping block 46 moves from the inside of the clamping groove 43 to the concave part on the outer surface of the cam 41. Release the cam 41 to make the first spring 44 drive it to reset. Therefore, when the inclined plate 5 drives the rotating cylinder 6 to rotate, it can drive the rotating pipe 12 to rotate, so that the rotating pipe 12 drives the cam 41 arranged on the outer surface to rotate, driving the clamping block 46 on the concave surface to move to the convex surface, which can drive the scraper 3 to rise. When moving from the convex surface to the concave surface, it can make the scraper 3 reset by the tension spring 9 arranged at the bottom, achieving the up and down movement effect. And the scraper 3 can drive the lifting block 73 arranged on the side to move, so that the lifting block 73 slides inside the straight groove 75 at the end face of the moving ring 77, playing a role in limiting.

[0042] Embodiment 2

[0043] Please refer to Figures 7-8 , this utility model provides a technical solution:

[0044] Different from Embodiment 1, a plurality of circular grooves 10 are opened on the outer surface of the inclined plate 5. Arranging a plurality of circular grooves 10 on the inclined plate 5 can reduce the direct impact force of the water flow on the inclined plate 5 and increase the service life of the inclined plate 5. A ball 11 is movably embedded inside the rotating cylinder 6, and the outer surface of the ball 11 is movably arranged on the outer surface of the spray pipe 2. The arranged ball 11 can reduce the friction force and maximize the use of the force generated by the water flow.
