Description

Technical Field

[0001] The utility model belongs to the technical field of VC heat sinks and relates to a one-step forming stamping die for VC products. Background Art

[0002] With the increasing use of intelligent mobile phone functions, the quality of life has been greatly improved. The demand for mobile phone functions is also constantly pursuing more applications and intelligence, which requires mobile phone chips to provide excellent computing power. Of course, high-speed computing and processing will generate heat. The faster the computing speed and the longer the running time, the higher the heat generation. If the heat is not dissipated in time, the temperature of the phone will gradually increase. In serious cases, it may endanger the safety of the battery and damage the chip. Therefore, the heat dissipation function of the mobile phone cannot be ignored.

[0003] Mobile phone heat dissipation materials and forms are developing rapidly, with many updated and iterative products. Currently, VC heat dissipation is recognized by the mobile phone industry. The product is composed of two pieces of heat dissipation materials to form a closed space, and cooling liquid is injected into the closed space. VC heat dissipation technology will cause the water in the closed space to produce a "gas-liquid" two-phase conversion. That is, the liquid coolant absorbs the heat generated by the mobile phone and converts into gas to take the heat away. At the same time, the gas at the other end is converted into liquid due to the drop in temperature and flows back to the hot end, thereby effectively reducing the temperature of the mobile phone.

[0004] like Figure 4 As shown in the figure, the main structure of the traditional VC heat sink 3 includes: a nozzle structure 31 for liquid introduction and a convex structure 32 for increasing the heat dissipation area; therefore, the processing of the VC heat sink needs to go through four processing steps: cutting, forming the nozzle, forming the convex and cutting the shape; in traditional processing, four sets of independently operated processing modules are required to work in sequence, the processing procedures are relatively cumbersome, and the processing cost is high, which does not meet the processing needs of efficient development of the industry.

[0007] The stamping upper die includes: an upper die base and an upper die core arranged in the upper die base, wherein an upper die cavity for receiving the upper die core is formed in the upper die base, and the overall depth of the upper die cavity is greater than the main body height of the upper die core;

[0008] The stamping lower die includes: a lower die base and a lower die core arranged in the lower die base, and the upper die core is matched with the lower die core;

[0009] The upper end processing surface of the lower mold core is higher than the upper end surface of the lower mold base, and a nozzle forming part and a plurality of array-arranged forming convex points are formed on the processing surface of the lower mold core.

[0017] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. It should be understood that this application is not limited to the example embodiments disclosed herein. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
