[0002] In modern society, with the acceleration of urbanization and the increasing awareness of environmental protection, the demand for trash cans, as an indispensable sanitation facility in daily life and public environment, continues to rise. In order to meet the market's dual requirements for the quantity and quality of trash cans, efficient and precise production processes have become the key to the industry's development. Injection molding technology, with its advantage of being able to mass-produce plastic products with complex shapes and stable dimensions, has become the mainstream method of trash can production.

[0003] The traditional dual-cavity trash can injection molds currently in use produce two products simultaneously in a single injection cycle. The injection molding machine injects molten plastic into two cavities through the main runner and branch runner. After the melt fills the cavity, it is held under pressure to compensate for shrinkage, and then solidifies through a cooling system. After the mold opens, the ejector mechanism simultaneously ejects the two formed trash cans, and then the mold closes to enter the next cycle. During the process, it is necessary to ensure that the molding conditions of the two cavities are consistent to ensure stable product quality.

[0004] The traditional dual-cavity garbage can injection mold currently in use can produce two products simultaneously, but it cannot simultaneously demold the products and solve the problems of defects and burrs caused by demolding difficulties, which affect production efficiency. Therefore, a dual-cavity garbage can injection mold is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Reference Figures 1-3The present invention provides an embodiment of a dual-cavity trash can injection mold, including a cavity plate 1. The cavity plate 1 is one of the core molding components of the dual-cavity trash can injection mold, and the whole presents a cavity structure that is adapted to the shape of the trash can. A fixed mold base plate 3 is fixedly connected to the right side of the cavity plate 1. The fixed mold base plate 3 is fixed to the right side of the cavity plate 1 and is an important plate that plays a role in fixing and supporting in the mold. It not only provides a stable mounting base for the cavity plate 1, ensuring that the cavity plate 1 will not shift during injection molding, but also the inlet 4 on its right side is a key channel for molten plastic to enter the mold cavity. It can guide the plastic raw material smoothly into the mold cavity composed of the cavity plate 1 and the core 9, ensuring the orderly progress of the injection molding process. The cavity plate 2 is fixedly connected to the left side of the cavity plate 1, ensuring the stability and accuracy of the core 9 during the sliding process. At the same time, it also provides space for the installation and movement of the spraying frame 5, allowing the spraying frame 5 to slide smoothly on its left side and achieve the corresponding functions. The spraying frame 5 is slidably connected to the left side of the cavity plate 2. The top side of the spraying frame 5 is equipped with a filler cap 6, which can easily add mold release agents and other additives into the spraying frame 5. The spraying frame 5 evenly sprays the additive onto the surface of the relevant parts, which helps in the subsequent demolding process. Multiple evenly distributed fixing rods 7 are slidably connected to the inside of the spraying frame 5. Since the spraying frame 5 needs to slide during operation, the fixing rods 7 can prevent the internal parts from loosening or shifting due to sliding, ensuring the stability and reliability of the overall structure of the spraying frame 5, thereby ensuring that it can perform its spraying and other functions normally. A movable ring 8 is fixedly connected to the inside of the spraying frame 5. The movable ring 8 provides an installation position for the rotating ball core 17. Multiple evenly distributed rotating ball cores 17 are rotated inside the movable ring 8. When the spraying frame 5 slides, the rotating ball cores 17 will rotate with the movement of the spraying frame 5, leaving the release agent between them and the contacting parts to assist in demolding.

[0034] Reference Figure 4 and Figure 5The inner side of the cavity plate 1 is slidably connected to the core 9. The core 9 is an important component in the mold that cooperates with the cavity plate 1 to form the mold cavity. Its outer side is slidably connected to the inner side of the cavity plate 2 and the inner side of the spray frame 5, while its inner side cooperates with other components. The left side of the core 9 is fixedly connected to the core plate 10. At the same time, the inner side of the core plate 10 is slidably connected to the demolding plate 16, and the outer side is slidably connected to the spray frame 5. It plays a role in connecting and coordinating these components. The left side of the core plate 10 is fixedly connected to the functional plate 11. The functional plate 11 can also connect the core plate 10 to the support block 12 and other components. The top side is provided with many connecting grooves to form a stable overall structure, ensuring that the various functions of the mold can be performed normally during the working process. The left side of the functional plate 11 is slidably connected to the push plate 14, which transmits the force to the demolding plate 16 through the push rod 15, and finally realizes the demolding of the trash can. The support block 12 guides and limits the sliding of the push plate 14, ensuring that the push plate 14 can slide smoothly in a fixed direction. The push plate 14 is slidably connected to the right side of the push plate 14. The sliding of the push rod 15 inside the functional plate 11 ensures that the force transmission direction is accurate, so that the demolding template 16 can move according to the predetermined trajectory and smoothly detach the formed trash can from the core 9. The demolding template 16 is fixedly connected to the right side of the push rod 15. The structural design of the demolding template 16 is adapted to the shape of the trash can, which can ensure that the surface of the trash can will not be damaged during demolding and ensure product quality.

[0035] Reference Figures 1-5 Each functional plate 11 has a support block 12 fixedly connected to its left side, which provides precise guidance for the sliding of the push plate 14, ensuring that the push plate 14 can only slide along the track inside the support block 12, thus guaranteeing the accuracy and reliability of the demolding process. A moving mold base plate 13 is fixedly connected to the left side of the support block 12, which limits the maximum distance the push plate 14 can slide to the left, ensuring that the movement of the push plate 14 is within a reasonable range. The top and bottom sides of the push plate 14 are slidably connected to the inside of the support block 12. The outer side of the ejector plate 16 is slidably connected to the inner side of the core plate 10. Each spraying frame 5 has an injection cap 6 installed on its top side. The outer side of the spraying frame 5 is slidably connected to the inner side of the core plate 10. The outer side of the core 9 is slidably connected to the inner side of the cavity plate 2. The outer side of the core 9 is slidably connected to the inner side of the spraying frame 5. The right side of the moving mold base plate 13 abuts against the left side of the push plate 14. The outer side of the push rod 15 is slidably connected to the inner side of the functional plate 11. The right side of the fixed mold base plate 3 has an injection port 4, which is the channel for molten plastic to enter the mold cavity. Its shape and size are carefully designed to ensure that the molten plastic enters the mold cavity composed of the cavity plate 1 and the core 9 at a suitable speed and pressure, allowing the plastic to fully fill the entire cavity and ensuring the molding quality of the trash can.

[0036] Working principle: First, injection molding is performed. Molten plastic raw material enters the mold through the inlet 4 on the right side of the fixed mold base plate 3. Then, the raw material enters the double mold cavity formed by the cavity plate 1 and the core 9 along the channel. The cavity plate 1 and the core 9 are precisely aligned, and their shapes match the external and internal structures of the trash can, providing molding space for the raw material. During this process, the fixed mold base plate 3 provides stable support for the cavity plate 1, and the inlet plate 2 helps the core 9 maintain a stable position, ensuring the sealing and shape accuracy of the mold cavity. This allows the raw material to be fully filled and cooled and solidified in the mold cavity, initially forming the shape of the trash can. In the demolding stage, after the plastic has cooled and solidified in the mold cavity, the push plate 14 slides to the right along the track inside the support block 12 under the drive of external power. The support block 12 ensures that the sliding direction of the push plate 14 is accurate and stable. The movement of the push plate 14 drives the push rod 15 connected to it. The push rod 15 slides inside the functional plate 11, transmitting the thrust to the demolding plate 16. The demolding template 16 slides along the inner side of the core plate 10, directly acting on the formed trash can, pushing it off the core 9 to complete the demolding.

[0037] Meanwhile, the spraying frame 5 plays an auxiliary role in the demolding process. The release agent is added into the spraying frame 5 through the top filler cap 6. When the spraying frame 5 slides along the cavity plate 2 and the core plate 10, the inner movable ring 8 drives the rotating ball core 17 to rotate. During the rotation, the release agent is left on the surface of the core 9. The release agent is evenly sprayed on the surface of the core 9 and other components, further assisting in demolding. The fixing rod 7 ensures the stability of the internal structure of the spraying frame 5 and ensures that its function is normal. The moving mold base plate 13, as the foundation of the moving mold part, provides a stable support for the entire structure, withstands various forces during the injection and demolding process, and ensures the overall stability and safety of the mold.

[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.
