[0002] Injection molds are tools used in the plastics processing industry, working in conjunction with plastic molding machines to give plastic products a complete shape and precise dimensions. Due to the wide variety of plastic types and processing methods, and the varying complexity of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse.

[0003] Existing technologies may result in poor cooling during injection molding, making it difficult for heat inside the mold to dissipate in time. This can cause defects such as deformation and cracking in plastic products during the cooling process, seriously affecting product quality and production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology does not have a structure for cooling the equipment during operation, which makes it difficult to dissipate the heat inside the mold in time, making the plastic product prone to deformation during the cooling process. To this end, we propose an injection mold for plastic products with high cooling efficiency.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a high-efficiency injection mold for plastic products, including a first cooling water tank 1, a first mounting base 2 fixedly connected to the top of the first cooling water tank 1, a first template 3 installed inside the first mounting base 2, a first pressure plate 4 inserted into the surface of the first template 3, a first lifting bracket 5 installed on the top of the first pressure plate 4, a first cooling water pipe 6 installed on the surface of the first mounting base 2, a first water pump 7 installed at one end of the first cooling water pipe 6, a first outer shell 8 installed at the other end of the first cooling water pipe 6, a first top cover 9 installed on the top of the first outer shell 8, a first filter element 10 placed inside the first outer shell 8, two first clamping blocks 11 rotatably connected to both ends of the surface of the first outer shell 8 via a rotating shaft, a first limiting block 12 fixedly connected to both ends of the surface of the first top cover 9, the inner wall of the first limiting block 12 inserted into one end of the first clamping block 11, a first sliding groove 13 installed at one end of the first outer shell 8, and the other end of the first sliding groove 13 penetrating through one side of the first cooling water tank 1 and placed in the first cooling water tank. Inside the water tank 1, when the user starts the equipment for mold injection compression, the cooling water inside the first cooling water pipe 6 installed around the first mounting base 2 dissipates the heat generated during the compression injection of the first template 3 and the first pressure plate 4. The cooling water flows into the interior of the first outer shell 8 through the first cooling water pipe 6 and is filtered by the first filter element 10. It is then discharged into the interior of the first cooling water tank 1 through the first slide groove 13. The cooling plate installed inside the first cooling water tank 1 lowers the water temperature, and the water is then pumped by the first water pump 7 into the first cooling water pipe 6 to continue cooling the equipment. When the user needs to replace the first filter element 10, the user rotates the first clamping block 11 to both sides through the pivot, so that the first outer shell 8 and the first top cover 9 can be separated, allowing the user to replace the first filter element 10. Replacing the first filter element 10 improves the cooling efficiency of the equipment and ensures the filtration performance of the first filter element 10. By controlling the temperature during equipment operation, the service life of the mold and other related components is effectively extended, and the overall maintenance cost is reduced.

[0022] Reference Figure 3 and Figure 5 As shown in this embodiment: a first groove 13 is provided on one side of the first limiting block 12, and a first sliding buckle 14 is slidably connected to the inner wall of the first groove 13. The inner wall of the first sliding buckle 14 is slidably connected to the surface of the first clamping block 11. When the user inserts the first clamping block 11 into the inner wall of the first limiting block 12, the user moves the first sliding buckle 14 along the inner wall of the first groove 13 so that the first sliding buckle 14 restricts the first clamping blocks 11 on both sides, so that the first clamping blocks 11 cannot be unfolded to both sides. The connection between the first outer shell 8 and the first top cover 9 is more secure through the first sliding buckle 14.

[0023] Reference Figure 3 and Figure 5As shown in this embodiment: a first slide rod 15 is installed inside the first slide groove 13. One end of the first slide rod 15 passes through one side of the first slide buckle 14 and is fixedly connected to one side of the inner wall of the first slide groove 13. When the user moves the first slide buckle 14 along the inner wall of the first slide groove 13, the first slide buckle 14 moves on the surface of the first slide rod 15, so that the first slide buckle 14 will not deviate when moving, making the first slide buckle 14 more stable when being operated.

[0024] Reference Figure 3 and Figure 5 As shown in this embodiment: a first spring 16 is fixedly connected to one side of the first sliding buckle 14, and the other end of the first spring 16 is fixedly connected to one side of the inner wall of the first slide groove 13. When the user moves the first sliding buckle 14 along the inner wall of the first slide groove 13, the first sliding buckle 14 squeezes the first spring 16, causing the first spring 16 to store and compress. When the user needs the first sliding buckle 14 to return to its original position, the user releases the first sliding buckle 14, causing the first spring 16 to release and rebound, pushing the first sliding buckle 14 back to its original position. The operation of the device is made simpler by the first spring 16.

[0025] Reference Figure 3 and Figure 4 As shown in this embodiment: a first limiting rod 17 is installed inside the first housing 8. The surface of the first limiting rod 17 is slidably connected to the inner wall of the first filter element 10. When the user installs the first top cover 9 into the inside of the first top cover 9 along the surface of the first limiting rod 17, the first filter element 10 becomes more stable during device operation and will not be affected by positional shaking or displacement during device operation.

[0026] Reference Figure 3 and Figure 4 As shown in this embodiment: a first sealing gasket 18 is installed on the top of the first outer shell 8. When the user fixes the first top cover 9 to the first outer shell 8 in a fixed position, the sealing performance of the first top cover 9 is improved by the first sealing gasket 18.

[0027] Reference Figure 1 and Figure 3As shown in this embodiment: several first heat-conducting plates 19 are installed on both sides of the first mounting base 2. The inner wall of the first heat-conducting plate 19 is inserted into the surface of the first cooling water pipe 6. A first dust cover 20 is installed on the top of the first mounting base 2. A first cooling fan 21 is installed at both ends inside the first dust cover 20. A first guardrail 22 is installed on both sides of the first dust cover 20. When the user starts the equipment for injection molding compression, the heat on the surface of the first cooling water pipe 6 is concentrated by the first heat-conducting plate 19 and then discharged by the first cooling fan 21. The heat of the first heat-conducting plate 19 is discharged by the first cooling fan 21, which greatly improves the cooling efficiency of the mold. This not only shortens the injection molding cycle but also effectively avoids problems such as deformation or quality degradation of plastic products caused by overheating of the mold, thus improving the practicality of the equipment.

[0028] Working principle:

[0029] Step 1: When the user starts the equipment to perform mold injection compression, the cooling water in the first cooling water pipe 6 around the first mounting base 2 dissipates the heat generated during the compression injection of the first template 3 and the first pressure plate 4. The cooling water flows into the first outer shell 8 through the first cooling water pipe 6, is filtered by the first filter element 10, and then discharged into the first cooling water tank 1 through the first slide groove 13. In the first cooling water tank 1, the cooling plate lowers the temperature of the cooling water. Subsequently, the cooling water is returned to the first cooling water pipe 6 by the first water pump 7 to continue to dissipate heat for the equipment. When the first filter element 10 needs to be replaced, the user rotates the first clamping block 11 through the pivot to unfold it to both sides, so that the first outer shell 8 and the first top cover 9 can be separated, thereby allowing the replacement of the first filter element 10.

[0030] Step two: When the user needs to fix the first clamping block 11 and the first limiting block 12, the first clamping block 11 and the inner wall of the first limiting block 12 are first inserted into each other. The user moves the first sliding buckle 14 along the inner wall of the first sliding groove 13 and moves it through the surface of the first sliding rod 15 to restrict the first clamping blocks 11 on both sides and prevent them from unfolding to both sides, thereby enhancing the connection between the first outer shell 8 and the first top cover 9. During the movement of the first sliding buckle 14, it will squeeze the first spring 16 to store and compress it. When the first sliding buckle 14 needs to return to its original position, the first sliding buckle 14 is released and the first spring 16 is released and rebounded, pushing the first sliding buckle 14 back to its original position. When the user installs the first top cover 9 into the first outer shell 8 along the surface of the first limiting rod 17.

[0031] Step 3: When the user fixes the first top cover 9 to the first outer shell 8, the sealing performance of the first top cover 9 is enhanced by the first sealing gasket 18. When the equipment is started to perform injection compression, the first heat conduction plate 19 gathers the heat on the surface of the first cooling water pipe 6, and then the first heat dissipation fan 21 dissipates this heat.

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.
