Description

Technical Field

[0001] This utility model relates to the field of water-cooled plate production and processing technology, and in particular to a water-cooled plate roll coating mold. Background Technology

[0002] In the manufacturing process of water-cooled plates, the machining accuracy of the flow channel cavity directly affects the heat dissipation efficiency and reliability of the water-cooled plate. Traditional roller coating molds typically adopt an integral structure, which presents the following technical problems:

[0003] The integral cavity needs to be formed in one step by high-precision machining equipment, which is costly and time-consuming. Multi-part combination molds rely on external positioning structures, which are prone to cavity misalignment and flow channel deformation. The mold cavity and flow channel plate have insufficient fit, which can easily cause material overflow or insufficient filling during the roll coating process. The existing technology lacks a roll coating mold that can achieve high-precision flow channel cavity forming through modular template assembly.

[0004] Therefore, it is necessary to propose a water-cooled plate roll coating mold for the above technical solution. Utility Model Content

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0031] The following is in conjunction with the appendix Figure 1-9 To further describe this application, a water-cooled plate roller coating mold includes a first template 2, a second template 3, a third template 4, and a fourth template 5, which are assembled into a mold body 1.

[0032] Furthermore, the first template 2, the second template 3, the third template 4 and the fourth template 5 are respectively provided with a first cavity 6, a second cavity 7, a third cavity 8 and a fourth cavity 9, and the first cavity 6, the second cavity 7, the third cavity 8 and the fourth cavity 9 are connected in sequence.

[0033] The first cavity 6, the second cavity 7, the third cavity 8 and the fourth cavity 9 form the mold cavity 10. The mold cavity 10 fits into the runner plate 11. The mold cavity 10 is slightly larger than the runner cavity of the runner plate 11, so that the runner plate 11 fits better into the mold and there are no uneven parts.

[0034] Furthermore, the mold body 1 is provided with multiple positioning holes 12 and mounting holes 13, which play a role in positioning and fixing during the roller coating process.

[0035] Furthermore, the mold body 1 is made of PE4 base plate, which is a high-strength and corrosion-resistant material.

[0036] Furthermore, the surface of the mold cavity 10 is flat, so that the flux is rolled onto the plane of the flow channel plate 11, which is uniform and comprehensive, and there is no flux in the flow channel.

[0037] The beneficial effects of this utility model are:

[0038] The mold cavity 10 of this utility model roller coating mold is attached to the flow channel plate 11, so that the flux is rolled onto the plane of the flow channel plate 11, which is uniform and comprehensive. There is no flux in the flow channel, which ensures both the strength of the brazing and the cleanliness of the flow channel.

[0039] Modular assembly advantages: The processing difficulty of a single template is reduced, and it can be processed separately by EDM or CNC. After assembly, the overall accuracy reaches ±0.03mm, which shortens the processing cycle by 40% compared with the traditional integral mold. The positioning hole 12 and the mounting hole 13 cooperate to realize quick mold change, adapt to different specifications of flow channel plate 11, and the mold change time is ≤15 minutes.

[0040] Improved flow channel forming precision: The surface roughness Ra of the mold cavity 10 is Ra≤0.4μm, avoiding surface defects in the flow channel. After forming, the dimensional tolerance of the flow channel is controlled within ±0.05mm. The matching gap of 0.1-0.3mm on one side not only ensures the fluidity of the material, but also achieves precise filling through rolling pressure. The overflow rate is reduced from 15% of traditional molds to below 3%.

[0041] Material and structure optimization: PE4 base material is resistant to corrosion from thermally conductive adhesives / solders, and its service life is more than twice that of ordinary steel molds; the connected cavity design reduces material flow resistance, and the roller coating pressure is evenly distributed, making it suitable for continuous molding of runners with a depth of 0.2-1.5mm.

[0042] In use, the first template 2, the second template 3, the third template 4 and the fourth template 5 are assembled into the mold body 1. The mold body 1 is installed on the mounting frame on the brazing production line. When the water-cooled plate needs to be roller coated, the clamping robot places the flow channel plate 11 of the water-cooled plate on the mold body 1. Then, it passes through the roller coating fixture. The roller of the roller coating fixture applies brazing flux to the surface of the flow channel plate 11. Then, the clamping robot attaches the roller-coated flow channel plate 11 to the substrate of the water-cooled plate and brazes it together.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
