Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a cooling structure for mold slides. Background Technology

[0002] During die casting, molten metal at high temperatures is poured into the mold cavity. The mold is not cooled, and its surface temperature remains consistently high. At high temperatures, the affinity between the molten metal and the mold surface increases, making adhesion more likely. When the die-cast part is demolded, the adhered metal can be pulled apart by the mold surface, resulting in scratches and mold pull problems. For example, in aluminum alloy die casting, aluminum readily reacts chemically with the mold steel surface at high temperatures, and the uncooled mold exacerbates this adhesion tendency.

[0003] Furthermore, without mold cooling, the die-castings solidify slowly, failing to reach their ideal strength and hardness in time, making them more prone to deformation during demolding. Simultaneously, excessively high mold temperatures significantly reduce the effectiveness of the release agent. Premature failure or volatilization of the release agent at high temperatures prevents the formation of an effective protective lubricating film between the mold and the die-casting, resulting in a substantial increase in demolding resistance. This increased resistance can cause the die-castings to be scratched by the mold during demolding, leaving marks. Utility Model Content

[0004] In order to reduce the temperature of the mold after molten metal is introduced into the mold, and thus reduce the occurrence of mold pulling, this utility model provides a cooling structure for the mold slide.

[0005] This utility model provides a technical solution that adopts the following approach:

[0006] A cooling structure for a mold slide includes 3D water channels embedded within the mold. The 3D water channels are 3D printed parts. Multiple 3D water channels are distributed within the mold and are fitted to the mold cavity wall. The 3D water channels extend along the length direction of the mold's output direction. Water pipes are connected to the 3D water channels, and the water pipes provide flowing coolant to the 3D water channels.

[0007] Based on digital model files, 3D printing uses powdered metal or plastic and other bondable materials to print 3D water channels running through the mold layer by layer. Traditional water channels are created by CNC machining and milling drilling. This method is limited by the milling machine model, the specific shape of the mold, and other external structures, making it difficult to adapt the water channels to complex product molds and to arrange them according to the ideal path. This can result in the water channels being too far or too close to the mold surface, affecting the cooling effect and leading to mold pulling. 3D printing technology can precisely control the diameter, shape, and branches of the water channels. By optimizing the water channel design, it increases the contact area between the cooling medium and the mold and the heat exchange efficiency, improves the cooling speed, and reduces the occurrence of mold pulling due to uneven cooling.

[0008] Preferably, the 3D waterway is spiral-shaped.

[0009] Spiral water channels can be distributed more evenly around the mold cavity, resulting in a more consistent cooling rate across all parts of the mold. Compared to straight water channels, spiral water channels can better conform to the complex shape of the mold, reduce cooling blind spots, ensure uniform shrinkage of the casting during cooling, and avoid defects such as deformation and cracking caused by uneven cooling.

[0010] Furthermore, the spiral design increases the length of the cooling water channels and the contact area with the mold, allowing for more thorough heat exchange between the cooling medium and the mold. As the cooling medium flows through the spiral water channels, it can more effectively remove the heat generated by the mold during the die-casting process, improving cooling efficiency, reducing mold temperature, and ensuring that the mold operates within a suitable temperature range.

[0011] Preferably, there are two 3D water channels, which are respectively located on both sides inside the mold along the width direction of the mold.

[0012] Two 3D water channels are located at both ends of the mold, which improves the cooling efficiency and makes the overall cooling effect of the mold more uniform. The stable cooling environment helps maintain the performance stability of the mold material and reduces the hardness changes and wear on the mold surface caused by heat. At the same time, uniform cooling also makes the wear of the mold during casting demolding more even, reducing localized excessive wear and further extending the service life of the mold.

[0013] Preferably, the 3D water channel extends along the length direction of the mold.

[0014] Preferably, the water pipe is connected to one end of the 3D waterway.

[0015] Coolant flows from the end of the 3D water channel into the 3D water channel, allowing the coolant to stably fill the entire 3D water channel, which is beneficial for making full use of the overall 3D water channel.

[0016] Preferably, a connector is provided between the two 3D water channels, and the connector is integrally connected to the 3D water channels.

[0017] The design of the connectors prevents the two annular spiral 3D water channels from rotating relative to each other, which helps to improve the stability of the 3D water channels built into the mold.

[0018] Preferably, the connector is located at the end of the 3D waterway away from the water pipe.

[0019] The connectors and water pipes are located at opposite ends of the 3D waterway, making the overall structure more rationally distributed.

[0020] Preferably, the mold also has a water passage through it, which allows coolant to be directly input or is used to position water pipes.

[0021] The water channel design makes the connection between the external water pipe and the 3D water system more secure, preventing leakage.

[0022] In summary, this utility model has the following beneficial technical effects:

[0023] Based on digital model files, 3D printing uses powdered metal or plastic and other bondable materials to print 3D water channels running through the mold layer by layer. Traditional water channels are created by CNC machining and milling drilling. This method is limited by the milling machine model, the specific shape of the mold, and other external structures, making it difficult to adapt the water channels to complex product molds and to arrange them according to the ideal path. This can result in the water channels being too far or too close to the mold surface, affecting the cooling effect and leading to mold pulling. 3D printing technology can precisely control the diameter, shape, and branches of the water channels. By optimizing the water channel design, it increases the contact area between the cooling medium and the mold and the heat exchange efficiency, improves the cooling speed, and reduces the occurrence of mold pulling due to uneven cooling.

[0027] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0028] This utility model discloses a cooling structure for mold slides.

[0029] Reference Figure 1 as well as Figure 2 A cooling structure for a mold slide includes a 3D water channel 2 disposed within a mold 1. The 3D water channel 2 is a 3D printed part. Multiple 3D water channels 2 are provided and distributed within the mold 1. The 3D water channels 2 are fitted to the cavity wall of the mold 1 and extend along the length direction of the output direction of the mold 1. The 3D water channels 2 are connected to water pipes, which provide flowing coolant to the 3D water channels 2.

[0030] Based on digital model files, 3D water channels 2, penetrating the mold 1, are printed layer by layer using powdered metal or plastic and other bondable materials. Traditional water channels are created by CNC machining and milling drilling. This method is limited by the milling machine model, the specific shape of the mold 1, and other external structures, making it difficult to adapt the water channels to complex product molds and to arrange them according to ideal paths. This can result in water channels being too far or too close to the mold 1 surface, affecting cooling efficiency and potentially causing mold pull. 3D printing technology can precisely control the diameter, shape, and branches of the water channels. By optimizing the water channel design, the contact area between the cooling medium and the mold 1 is increased, and the heat exchange efficiency is improved, increasing the cooling speed and reducing the risk of mold pull due to uneven cooling.

[0031] Reference Figure 1 as well as Figure 2 In this embodiment, the 3D waterway 2 is spiral-shaped.

[0032] The spiral water channels can be distributed more evenly around the cavity of mold 1, making the cooling rate of each part of mold 1 more consistent. Compared with straight water channels, spiral water channels can better conform to the complex shape of mold 1, reduce cooling blind spots, ensure that the casting shrinks evenly during the cooling process, and avoid defects such as deformation and cracking caused by uneven cooling.

[0033] Furthermore, the spiral design increases the length of the cooling water channel and the contact area with mold 1, allowing for more thorough heat exchange between the cooling medium and mold 1. As the cooling medium flows through the spiral water channel, it can more effectively remove the heat generated by mold 1 during the die-casting process, improving cooling efficiency, reducing the temperature of mold 1, and ensuring that mold 1 operates within a suitable temperature range.

[0034] Reference Figure 1 as well as Figure 2 In this embodiment, there are two 3D water channels 2, which are respectively located on both sides inside the mold 1 along the width direction of the mold 1.

[0035] Two 3D water channels 2 are located at both ends of mold 1, which can improve the cooling efficiency of mold 1 and make the overall cooling effect of mold 1 more uniform. The stable cooling environment helps to maintain the performance stability of mold 1 material and reduce the hardness changes and wear on the surface of mold 1 caused by heat. At the same time, uniform cooling also makes the wear of mold 1 more uniform when the casting is demolded, reducing the occurrence of excessive local wear and further extending the service life of mold 1.

[0036] Reference Figure 1 as well as Figure 2 In this embodiment, the 3D water channel 2 extends along the length direction of the mold 1.

[0037] Reference Figure 1 as well as Figure 2 In this embodiment, the water pipe is connected to one end of the 3D waterway 2.

[0038] Coolant flows into the 3D water channel 2 from the end of the channel, allowing the coolant to fill the entire flow of the 3D water channel 2 stably, which is beneficial for making full use of the entire 3D water channel 2.

[0039] Reference Figure 1 as well as Figure 2 In this embodiment, a connector 3 is provided between the two 3D water channels 2, and the connector 3 is integrally connected to the 3D water channel 2.

[0040] The connection 3 prevents the two annular spiral 3D water channels 2 from rotating relative to each other, which helps to improve the stability of the 3D water channels 2 inside the mold 1.

[0041] In this embodiment, the connector 3 is a rectangular plate with a width greater than the diameter of the 3D water channel 2. The rectangular plate and the 3D water channel 2 are printed as a single unit using 3D printing technology.

[0042] Reference Figure 1 as well as Figure 2 In this embodiment, the connector 3 is located at the end of the 3D waterway 2 away from the water pipe.

[0043] Connector 3 and water pipe are located at opposite ends of 3D water channel 2, making the overall structure more rationally distributed. Mold 1 also has a water passage 4, which allows for direct coolant input or is used to position the water pipe.

[0044] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
