Description

Technical Field

[0001] This invention relates to the field of production equipment technology, and more specifically, to a molding apparatus and molding method. Background Technology

[0002] Existing heat dissipation products mainly target various heat sources to achieve a combination of passive and active heat dissipation. Taking conventional heat sink structures as an example, they rely on the direct contact between the heat sink body and the heat source to quickly conduct and accumulate the heat generated by the heat source, achieving initial heat transfer and dissipation. Then, through the coolant circulation pipes, the coolant circulates along the surface of the heat sink, carrying away the heat stored in the heat sink, completing the overall heat exchange and cooling, and achieving the purpose of stabilizing the operating temperature of the heat source.

[0003] However, existing conventional water cooling solutions have obvious technical defects: the coolant flows quickly along the heat sink channel, and the effective contact time with the heat exchange surface of the heat sink is too short, resulting in insufficient heat exchange, low heat exchange efficiency, and inability to quickly and completely remove all the heat conducted by the heat sink, resulting in poor overall heat dissipation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a molding apparatus and a molding method.

[0005] The present invention discloses a molding device, comprising: a support member, several fixing components, a plurality of first molding members and a plurality of second molding members, wherein the plurality of first molding members are spaced apart along a first direction, the plurality of second molding members are spaced apart along a second direction, the plurality of first molding members are respectively staggered with the plurality of second molding members, and forming a plurality of molding holes, the support member having a processing hole, and the plurality of molding holes being directly opposite to and connected to the processing hole. The fixing component includes a locking fastener and a plurality of first fixing members. The plurality of first fixing members are disposed on the support member along a first direction or a second direction, and an accommodating opening is formed between two adjacent first fixing members. The locking fastener passes through the plurality of first fixing members, and one end of the plurality of first molding members or one end of the plurality of second molding members is respectively locked in the plurality of accommodating openings. The product and the processing hole are positioned directly opposite each other, and the molding material injected from the outside passes through the molding hole and the processing hole and is then formed on the surface of the product.

[0018] The following drawings disclose several embodiments of the present invention. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0019] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this invention.

[0020] Example 1 like Figures 1-3 As shown, Figure 1 This is a three-dimensional structural diagram of the molding device; Figure 2 This is a breakdown diagram of the molding device; Figure 3 for Figure 1Enlarged view of section A. The molding device includes a support member 1, several fixing components 2, multiple first molding parts 3, and multiple second molding parts 4. The fixing components 2 are disposed on the support member 1. The multiple first molding parts 3 are spaced apart along a first direction, and the multiple second molding parts 4 are spaced apart along a second direction. The multiple first molding parts 3 and multiple second molding parts 4 are staggered and form multiple molding holes 5. The fixing components 2 are connected to at least one end of the multiple first molding parts 3, or the fixing components 2 are connected to at least one end of the multiple second molding parts 4. In use, the product 100 is placed at a designated position on the support member 1, with the product 100 facing the multiple molding holes 5, i.e., the multiple molding holes 5 can be projected orthogonally onto the surface of the product 100. Molding material is sprayed in by an external device. After the externally sprayed molding material passes through the multiple molding holes 5, it forms the corresponding shape on the surface of the product 100. In this embodiment, the first direction is the X-axis direction, the second direction is the Y-axis direction, and the third direction is the Z-axis direction.

[0021] In practical applications, the support member 1 has a machining hole 11, which is directly opposite to the molding hole 5 and is connected to it. Molding material injected from the outside passes through the molding hole 5 and the machining hole 11 in sequence, and then the molding material is molded into the corresponding shape on the surface of the product 100. Specifically, the molding material is molded into a columnar structure on the surface of the product 100.

[0022] Please refer to the following: Figure 4 and Figure 5 , Figure 4 This is a partial structural diagram of the fixing component 2 and the first molded part 3; Figure 5 This is a diagram showing the disassembled state of the fixing component 2 and the first molded part 3. Taking the fixing component 2 connected to one end of multiple first molded parts 3 as an example, the fixing component 2 includes a locking fastener 21 and multiple first fixing members 22. The multiple first fixing members 22 are arranged along a first direction, and the locking fastener 21 passes through the multiple first fixing members 22, locking the multiple first fixing members 22. One end of the multiple first molded parts 3 is connected to the multiple first fixing members 22 respectively. In specific applications, two adjacent first fixing members 22 together form a receiving opening 20. One end of the first molded part 3 is locked in the receiving opening 20. The multiple first fixing members 22 cooperate with the locking fastener 21 to lock the multiple first molded parts 3 in the receiving opening 20, preventing the first molded parts 3 from shifting during the injection of molding material, thus affecting the final molding effect.

[0023] The locking device 21 includes a rod 211 and a limiting body 212. The first fixing member 22 has locking holes 222. The rod 211 passes through multiple locking holes 222 of the first fixing member 22. The limiting body 212 is disposed on the rod 211 and abuts against the first fixing member 22 located at its ends. In this embodiment, there are two limiting bodies 212, each screwed to both ends of the rod 211 and abutting against the first fixing members 22 located at both ends. In use, by rotating the limiting body 212, relative movement occurs between the limiting body 212 and the rod 211, changing the distance between the two limiting bodies 212. When the distance between the two limiting bodies 212 decreases, the multiple first fixing members 22 are compressed. Specifically, the limiting body 212 can be an existing nut.

[0024] Furthermore, the fixing component 2 also includes a second fixing member 23, which is disposed on the support member 1, and multiple first fixing members 22 are disposed on the second fixing member 23. The second fixing member 23 has a receiving groove 231 and a sliding groove 232, both of which are opened along a first direction and are connected. The first fixing member 22 also has a slider 221, which is located in the receiving groove 231 and is slidably disposed in the sliding groove 232. The arrangement of the slider 221 and the sliding groove 232 facilitates the installation of multiple first fixing members 22 and also provides a limiting effect for the multiple first fixing members 22. In this embodiment, there are two sliding grooves 232, which are oppositely disposed on both sides of the receiving groove 231. Correspondingly, there are also two sliders 221, which are slidably disposed in the two sliding grooves 232 respectively. During installation, multiple first fixing parts 22 and multiple first molding parts 3 can be assembled alternately. That is, after placing one first fixing part 22, one first molding part 3 is placed, and then another first fixing part 22 is placed, and so on.

[0025] Furthermore, the molding device also includes a limiting member 6, which is disposed on the support member 1 and located on the side of the second fixing member 23. The limiting member 6 abuts against the side of the second fixing member 23. By setting the limiting member 6, the position of the second fixing member 23 can be fixed, preventing the second fixing member 23 from shifting position during processing. In this embodiment, there are two limiting members 6, which are respectively disposed on opposite sides of the second fixing member 23, and the two limiting members 6 abut against the two sides of the second fixing member 23.

[0026] In addition, the number of fixing components 2 can be four, with two fixing components 2 respectively connecting to the two ends of multiple first molded parts 3; the other two fixing components 2 respectively connecting to the two ends of multiple second molded parts 4. The number of limiting components 6 can also be adjusted accordingly. For example, the number of limiting components 6 can be eight, with two limiting components 6 corresponding to each second fixing part 23 for limiting.

[0027] A first molded part 3 has multiple first slots 31, which are spaced apart along a second direction. Multiple second molded parts 4 can be respectively engaged in the first slots 31. Alternatively, a second molded part 4 has multiple second slots 41, which are spaced apart along a first direction. Multiple first molded parts 3 can be respectively engaged in the second slots 41. Or, a first molded part 3 has multiple first slots 31, and a second molded part 4 has multiple second slots 41, with the first slots 31 and second slots 41 engaging with each other.

[0028] In this embodiment, the first fixing member 22, the first molding member 3 and the second molding member 4 are all plate-shaped or sheet-shaped structures.

[0029] In summary, the molding device can form a columnar structure on the heat sink. When the coolant flows through the columnar structure area, it will effectively prolong the contact time between the coolant and the heat sink, allowing for sufficient heat exchange and thus quickly removing the heat conducted by the heat sink, thereby improving the overall heat dissipation effect.

[0030] Example 2 like Figures 6-8 As shown, Figure 6 This is another three-dimensional structural diagram of the molding device; Figure 7 A partial structural schematic diagram of the fixing component 2, the first molding part 3, and the second molding part 4; Figure 8 This is a schematic diagram of the structure of the first molded part 3 and the second molded part 4. The difference between this embodiment and Embodiment 1 is that the first molded part 3 and the second molded part 4 are stacked. Specifically, the first molded part 3 and the second molded part 4 are distributed along a third direction, and the first molded part 3 is located on top of the second molded part 4 (the direction pointed to by the arrow in the Z-axis direction is "top").

[0031] In addition, in this embodiment, the first molded component 3 and the second molded component 4 are tubular structures. Multiple first molded components 3 can be independent tubular structures, or a sufficiently long tubular body can be bent to fit multiple receiving ports 20, thereby forming multiple corresponding first molded components 3. The second molded component 4 is in the same situation as the first molded component 3. Alternatively, a sufficiently long tubular body can be bent to first form one of the multiple first molded components 3 or multiple second molded components 4, and then the remaining portion of the tubular body can be bent to form the other of the multiple first molded components 3 or multiple second molded components 4.

[0032] Example 3 A molding method employs the molding apparatus described in Embodiment 1 or Embodiment 2. An external device sprays the required molding material into the product. The externally sprayed molding material sequentially passes through molding holes 5 and processing holes 11, then falls onto the surface of the product 100, whereby a corresponding shape is formed. Taking the product 100 as a heat sink as an example, one side of the heat sink is in contact with a heat source, while the other side has multiple columnar structures formed. In a liquid cooling scenario, the flow path of the coolant changes due to the obstruction caused by the multiple columnar structures, thereby increasing the contact time between the coolant and the heat sink to achieve a better cooling effect.

[0033] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
