[0002] With the development of science and technology and the improvement of living conditions, the consumption level has increased, leading to an increase in household waste. In order to maintain a clean and tidy living environment, trash cans are used to collect garbage. Most trash cans are plastic products produced by injection molding, which have waterproof and impact-resistant properties.

[0003] The injection molds used for trash cans currently typically consist of a fixed mold base plate, a cavity plate, and a core plate. Raw materials are injected into the mold through the injection holes inside the fixed mold base plate, and then the material is formed inside the cavity plate and the core plate. After cooling, the mold is demolded to complete the production process.

[0004] Currently used garbage can injection molds require manual collection of garbage cans after demolding during the manufacturing process. The finished products are then collected, sorted, and placed in a fixed storage area. To address this issue, a striped garbage can internal cylinder injection mold is proposed to solve the above problems. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-6This utility model provides an embodiment of an injection mold for the inner cylinder of a striped trash can, including a fixed mold base plate 1. The fixed mold base plate 1 has an inlet for injection molding raw materials, which are injected into the mold through the inlet. A cavity plate 2 is fixedly connected to the right side of the fixed mold base plate 1. A rack 3 is slidably connected to the bottom of the fixed mold base plate 1. A movable mold base plate 4 is fixedly connected to the right end of the rack 3, serving as a support structure. A support block 5 is fixedly connected to the top and bottom of the left side of the movable mold base plate 4, also providing support. A core plate 6 is fixedly connected to the left side of the support block 5. The cavity plate 2 and the core plate 6 work together to shape the material. A gear post 7 is meshed with the bottom of the rack 3. A worm gear 8 is fixedly connected to the front of the column 7. The movement of the rack 3 drives the gear column 7 to rotate, which in turn drives the worm gear 8 to rotate synchronously. Multiple evenly distributed support rings 9 are rotatably connected to the outer periphery of the worm gear 8 and the gear column 7. The support rings 9 are used to support and fix the gear column 7 and the worm gear 8. A bracket 10 is fixedly connected to the bottom of the support ring 9. The bracket 10 serves as a support structure and plays a supporting role. A gear rod 11 is meshed with the top of the worm gear 8. Connecting rods 12 are fixedly connected to the left and right sides of the gear rod 11. A storage basket 13 is fixedly connected to the top of the connecting rod 12. The gear rod 11 rotates inside the bracket 10 under the action of the worm gear 8, thereby driving the connecting rod 12 and the storage basket 13 to rotate. A demolding component is provided on the left side of the moving mold base plate 4.

[0035] Reference Figures 3-5 The demolding assembly includes a fixed rod 14, which is slidably connected inside the moving mold base plate 4. An ejector plate 15 is fixedly connected to the left side of the fixed rod 14, and an ejector pin push plate 16 is fixedly connected to the left side of the ejector plate 15. Multiple evenly distributed ejector pins 17 are fixedly connected to the left side of the ejector pin push plate 16, and a spring 22 is fixedly connected to the left side of the ejector pin push plate 16. When the device moves to its end, the support structure blocks the fixed rod 14 from moving, while the moving mold base plate 4 still moves to the right. The fixed rod 14 moves to the left relative to the moving mold base plate 4, causing the ejector plate 15 to move, and at the same time, the ejector pin push plate 16 to move, causing the ejector pins 17 to move, thus acting on the formed trash can to demold it.

[0036] Reference Figures 2-4The bottom of the fixed mold base plate 1 is provided with a slide groove 18. The rack 3 is slidably connected inside the slide groove 18. The rack 3 is fixed inside the moving mold base plate 4 and is connected to the fixed mold base plate 1 through the slide groove 18. The moving mold base plate 4 is provided with multiple evenly distributed slide grooves 29. The core plate 6 is provided with multiple evenly distributed slide grooves 30. The fixing rod 14 is slidably connected inside the slide groove 29. The ejector pin 17 is slidably connected inside the slide groove 30. The bracket 10 is provided with a groove 21. The gear rod 11 is rotatably connected inside the groove 21. The core plate 6 is installed on the right side of the cavity plate 2. The spring 22 is fixed on the right side of the core plate 6. The spring 22 exerts a force on the ejector pin push plate 16 to reset it. The ejector pin push plate 16 is slidably connected to the opposite side of the support block 5.

[0037] Working principle: After injection molding is completed, the mold is cooled and solidified by the cooling system. The moving mold base plate 4 drives the core plate 6 to move to the right, and simultaneously drives the rack 3 to move to the right. The rack 3 drives the gear column 7 to rotate clockwise, and the gear column 7 drives the worm gear 8 to rotate synchronously. The worm gear 8 drives the gear rod 11 to rotate upward, which in turn drives the storage basket 13 to rotate upward through the connecting rod 12. When the moving mold base plate 4 is about to reach its end, the support structure at the end blocks the fixed rod 14, causing the fixed rod 14 to move to the left relative to the moving mold base plate 4. This drives the ejector plate 15 to move to the left, and the ejector plate 15 drives the ejector pin 17 push plate to move to the left. The ejector pin 17 push plate drives the ejector pin 17 to move within the slide groove 20, thus causing the ejector pin 17 to extend out of the core plate 6. The core plate 6 moves to the right together with the moving mold base plate 4, while the ejector pin 17 moves in the opposite direction. This exerts a force on the molded product on the core plate 6, causing it to detach from the core plate 6. At this time, through the cooperation of structures such as the rack 3, the collection basket 13 reaches the position on the left side of the core plate 6. The collection basket 13 is slightly larger than the minimum cross-section of the molded product and slightly smaller than the maximum cross-section of the molded product. Under the action of the ejector pin 17, the demolded product just enters the interior of the collection basket 13 and is collected by the collection basket 13. Then the moving mold base plate 4 moves to the left to start a new round of injection molding process. After the fixing rod 14 is separated from the support structure, under the action of the spring 22, the ejector pin 17 push plate moves to the right, driving the ejector pin 17 back to its original position. At the same time, the rack 3 moves to the left. Through the cooperation of structures such as the gear column 7, worm gear 8 and gear rod 11, the collection basket 13 rotates with the molded product in the opposite direction to the previous one, thereby completing the automatic collection of the demolded product.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
