They are widely used in the production of various plastic products, possessing high molding efficiency and a long service life. Through rational mold design, plastic molds can effectively control temperature, pressure, and molding time to ensure the fluidity and cooling effect of the plastic, thereby producing plastic products that meet the required specifications.

[0003] Traditional plastic molds generally consist of a mold base, cavity, core, cooling system, injection system, and heating system. The base provides the supporting structure for the mold; the cavity and core determine the shape and size of the molded plastic part; the cooling system regulates the mold temperature to ensure that the plastic cools and solidifies evenly after injection; the injection system injects the plastic raw material into the mold cavity; and the heating system ensures that the mold reaches a suitable operating temperature.

[0004] Traditional plastic molds typically use internal cooling pipes that conduct heat through the mold's metal components. This structure makes the connection between the cooling pipes and the external coolant complex. The cooling pipes are usually embedded in the mold wall or arranged through precise channels, requiring long connecting pipes or complex interfaces for the external coolant piping, increasing the difficulty of installation and maintenance. This design hinders the uniformity and efficiency of coolant flow, leading to localized overheating or uneven cooling of the mold, thus affecting product quality and mold lifespan. Utility Model Content

Detailed Implementation

[0018] 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.

[0019] Reference Figures 1-3This utility model provides an embodiment of a precision plastic mold, including a mold base 1, a mold body 2 on the top of the mold base 1, and multiple cooling pipes 3 inside the mold body 2 for conducting coolant to the inside of the mold to ensure uniform cooling of the plastic during injection, control the mold temperature, avoid hot spots or deformation during molding, and thus improve the molding quality of the product. Multiple water pipes 5 are provided on the side wall of the mold body 2 for injecting and discharging coolant, ensuring that the mold body 2 can complete the cooling process in a short time, improving production efficiency. A connecting assembly is provided on the side wall of the mold body 2; the connecting assembly includes multiple connecting pillars 4, which are fixedly connected to the side wall of the mold body 2. Multiple turntables 8 are fixedly connected to the outer wall of each connecting pillar 4, and a side plate 6 is rotatably connected inside each turntable 8. The design of the turntables 8 and side plates 6 allows the mold to achieve precise alignment of parts by adjusting the angle, ensuring the stability of the mold and preventing defects during injection molding. Necessary displacement reduces molding errors. Each side plate 6 is fixedly connected to a buckle plate 7. The buckle plate 7 is slidably connected inside the slot 10, which can effectively achieve a stable connection of the water pipe 5 and prevent the water pipe 5 from falling off or loosening due to vibration or external force. The outer wall of the water pipe 5 is fixedly connected to a sleeve post 9. The sleeve post 9 has a slot 10 inside, and the buckle plate 7 is slidably connected inside the slot 10. This design makes the connection of the water pipe 5 more stable and enhances the service life of the mold. The side plate 6 is provided with a spring 21. One end of the spring 21 is fixedly connected to the outer wall of the connecting post 4, and the other end is fixedly connected to the side plate 6. The elasticity of the spring 21 ensures that the side plate 6 can automatically reset after being released, ensuring reliable connection and quick loading and unloading of various parts of the mold. The side wall of the mold body 2 is provided with multiple fixing components to reinforce various parts of the mold throughout the injection molding process, preventing the mold from shifting or deforming under high pressure and high temperature working environment, thereby further ensuring the stability of the mold and the precision of the injection molded parts.

[0020] Specifically, when injecting coolant into the cold pipe 3 inside the mold body 2, align one end of the water pipe 5 with the connecting post 4. At this time, press multiple side plates 6 to make the side plates 6 rotate inside the turntable 8 and change the tilt angle. Then the angle of the side plates 6 changes. After releasing the side plates 6, the elastic force of the spring 21 pushes the side plates 6 so that the buckle 7 is fastened inside the slot 10, thereby realizing the connection between the water pipe 5 and the mold body 2.

[0021] Reference Figure 4 and Figure 5The fixing assembly includes multiple side platforms 11, the side walls of which are fixedly connected to the side walls of the mold body 2. Each side platform 11 has a sliding post 12 inside, and a bottom post 13 is fixedly connected to the bottom of the insertion post 12. The bottom post 13 is slidably connected to the inside of the mold base 1. A first sliding groove 14 is opened inside the insertion post 12, and a second sliding groove 15 is opened inside the bottom post 13. A sliding shaft 16 is provided inside the insertion post 12, and the sliding shaft 16 is slidably connected to the inside of the first sliding groove 14. A bottom shaft 17 is fixedly connected to the bottom of the sliding shaft 16, and the bottom shaft 17 is slidably connected to the inside of the second sliding groove 15. An outer ring 18 is fixedly connected to the outer wall of the bottom shaft 17. Multiple retaining plates 19 are slidably connected inside the bottom post 13. A second spring 20 is sleeved on the outer wall of the sliding shaft 16. One end of the second spring 20 is fixedly connected to the outer wall of the sliding shaft 16, and the other end of the second spring 20 is fixedly connected to the inside of the insertion post 12.

[0022] Specifically, during the injection molding process, vibration may occur due to temperature and other factors. To avoid adverse effects on the injection molded parts, multiple inserts 12 are inserted into the side platform 11, and the bottom insert 13 enters the mold base 1. Then, the spring force of the second spring 20 pushes the sliding shaft 16, causing the sliding shaft 16 to slide inside the first slide groove 14, and the bottom shaft 17 to slide inside the second slide groove 15. This enables the outer ring 18 to push the clamping plate 19. The clamping plate 19 limits the mold base 1 inside the mold base 1, ensuring that the mold base 1 and the mold body 2 remain stable, avoiding the impact of vibration on the injection molded parts, thereby ensuring the stability of the production process and the quality of the products.

[0023] Working principle: First, when injecting coolant into the cold pipe 3 inside the mold body 2, align one end of the water pipe 5 with the connecting post 4. At this time, press multiple side plates 6, causing the side plates 6 to rotate inside the turntable 8 and change their tilt angle. Then, after the side plate 6 angle changes, release the side plate 6 and push it with the elastic force of spring 1 21, so that the buckle 7 is fastened inside the slot 10, realizing the connection between the water pipe 5 and the mold body 2. Due to temperature and other factors during the injection molding process, there is vibration. In order to avoid affecting the injection molded parts, multiple inserts 12 are inserted into the side platform 11, and the bottom post 13 enters into the mold base 1. Then, the elastic force of spring 20 pushes the sliding shaft 16, so that the sliding shaft 16 slides inside the sliding groove 14 and the bottom shaft 17 slides inside the sliding groove 2 15, realizing the outer ring 18 pushing the clamping plate 19. The clamping plate 19 limits the mold base 1 inside the mold base 1, ensuring the stability of the mold base 1 and the mold body 2, avoiding the impact on the injection molded parts, and ensuring production quality.

[0024] 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.
