[0001] This utility model relates to the field of mold technology, specifically to an extrusion mold for irregularly shaped heat dissipation elements. Background Technology

[0002] A heat sink typically consists of a base plate and multiple aluminum heat sink fins. The ends of the heat sink fins are fixed to the base plate. The heat sink fins have a large heat dissipation area, which can meet the heat dissipation requirements of the heat source.

[0003] Regular heat dissipation components can be machined, while irregularly shaped heat dissipation components need to be cast. Once the irregularly shaped heat dissipation components are cast, they are difficult to remove from the mold. To solve this problem, an extrusion mold is proposed to facilitate the removal of irregularly shaped heat dissipation components from the mold. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an extrusion mold for irregularly shaped heat dissipation components, which has the advantages of convenient and rapid extrusion and removal of irregularly shaped heat dissipation components, thus solving the aforementioned problems.

[0005] To achieve the aforementioned goal of conveniently and quickly extruding irregularly shaped heat dissipation components, this utility model provides the following technical solution: an extrusion mold for irregularly shaped heat dissipation components, comprising a base, a mold block detachably mounted on the top of the base via a bracket, cylinder one and cylinder two fixedly mounted in front of and behind the mold block, a push plate fixedly mounted on the output end of cylinder one, an extrusion punch fixedly mounted on the side of the push plate, a side cover plate fixedly mounted on the output end of cylinder two, a protrusion block fixedly mounted on the side of the side cover plate, and a closing punch fixedly mounted on the side of the side cover plate and below the protrusion block.

[0006] Preferably, the mold block has an anisotropic heat dissipation element groove inside, and an anisotropic heat dissipation element body is cast inside the anisotropic heat dissipation element groove. The mold block has an upper fan-shaped cooling cavity and a lower fan-shaped cooling cavity inside, and a central cooling cavity is formed between the two lower fan-shaped cooling cavities. The two upper fan-shaped cooling cavities are interconnected, and the two lower fan-shaped cooling cavities are interconnected with the central cooling cavity. Cold water inlets and cooling water outlets are fixedly installed on the outer walls of the upper and lower fan-shaped cooling cavities.

[0007] Preferably, a groove corresponding to the protrusion is formed between the two upper fan-shaped cooling cavities, and a casting hole is provided between the groove and the protrusion.

[0008] Preferably, a side sealing plate is fixedly installed on the left side of the mold block by bolts. The surface of the side sealing plate is provided with a special-shaped hole corresponding to the extrusion punch. The extrusion punch is inserted into the special-shaped hole. The cross-sectional shape of the extrusion punch, the special-shaped hole, the special-shaped heat dissipation element groove, the special-shaped heat dissipation element body and the closing punch are consistent.

[0009] Preferably, elastic plates are fixedly installed on both sides of the top and bottom of the side cover plate, and a clamping head is fixedly installed at the end of the elastic plate. The outer wall of the mold block is provided with a groove corresponding to the clamping head and the elastic plate, and the outlet of the groove is provided with an inclined surface opposite to the clamping head.

The die block is equipped with an upper fan-shaped cooling cavity, a lower fan-shaped cooling cavity, and a central cooling cavity. The cooling water inlet and outlet are connected to an external circulating cooling water system, allowing the cooling water to flow in the cavities and accelerate the cooling and solidification of the molten metal. Then, cylinder two pushes open the side cover plate, the protruding block, and the closing punch. Cylinder one drives the extrusion punch to penetrate into the irregularly shaped heat sink component groove, and the extrusion punch pushes and extrudes the irregularly shaped heat sink component body out of the groove. This process enables convenient and rapid extrusion and removal of the irregularly shaped heat sink component body, solving the problem of traditional irregularly shaped heat sink components being difficult to remove.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-7 An extrusion die for an irregularly shaped heat dissipation element includes a base 1. A die block 3 is detachably mounted on the top of the base 1 via a bracket 2. A cylinder 4 and a cylinder 5 are fixedly mounted in front of and behind the die block 3, and the two cylinders are arranged in a staggered manner. A push plate 6 is fixedly mounted on the output end of the cylinder 4. An extrusion punch 7 is fixedly mounted on the side of the push plate 6. A side cover plate 8 is fixedly mounted on the output end of the cylinder 5. A protrusion block 9 is fixedly mounted on the side of the side cover plate 8. A closing punch 10 is fixedly mounted on the side of the side cover plate 8 and below the protrusion block 9.

[0016] Please see Figure 1-7The mold block 3 has an irregularly shaped heat dissipation element groove 11 inside. The closing punch 10 is inserted into the right opening of the irregularly shaped heat dissipation element groove 11 to close the right opening of the irregularly shaped heat dissipation element groove 11 during casting. The irregularly shaped heat dissipation element body 12 is cast inside the irregularly shaped heat dissipation element groove 11. Irregularly shaped slots are opened on both sides of the irregularly shaped heat dissipation element body 12, and irregularly shaped slots are opened at the bottom of the irregularly shaped heat dissipation element body 12. The irregularly shaped heat dissipation element body 12 is symmetrically distributed on both sides about its own central axis.

[0017] Please see Figure 8-9 The mold block 3 has an upper fan-shaped cooling cavity 13 and a lower fan-shaped cooling cavity 14 inside. A central cooling cavity 15 is formed between the two lower fan-shaped cooling cavities 14. The two upper fan-shaped cooling cavities 13 are interconnected, and the two lower fan-shaped cooling cavities 14 are interconnected with the central cooling cavity 15. Cold water inlets 16 and cooling water outlets 17 are fixedly installed on the outer walls of the upper and lower fan-shaped cooling cavities 13 and 14, respectively. The two water inlets are connected to an external cooling water circulation device, which facilitates the circulation of cooling water in the above-mentioned cavities and accelerates the rapid cooling of the workpiece.

[0018] Please see Figure 8-9 A groove 18 corresponding to the protrusion 9 is opened between the two upper fan-shaped cooling cavities 13. When the side cover plate 8 and the mold block 3 are closed, they and the protrusion 9 are inserted into the groove 18. A pouring hole 19 is provided between the groove 18 and the protrusion 9. Molten metal can be poured into the anisotropic heat dissipation element groove 11 through the pouring hole 19.

[0019] Please see Figure 1-7 A side sealing plate 20 is bolted to the left side of the mold block 3. The surface of the side sealing plate 20 has a shaped hole corresponding to the extrusion punch 7. The extrusion punch 7, the shaped hole, the irregular heat dissipation element groove 11, the irregular heat dissipation element body 12, and the closing punch 10 have the same cross-sectional shape. The extrusion punch 7 is inserted into the shaped hole, effectively closing the left side of the irregular heat dissipation element groove 11. After the closing punch 10 is opened, the extrusion punch 7 penetrates into the irregular heat dissipation element groove 11, thus extruding the irregular heat dissipation element body 12.

[0020] Please see Figure 1-7 Both sides of the top and bottom of the side cover plate 8 are fixedly installed with elastic plates 21. A clamping head 22 is fixedly installed at the end of the elastic plate 21. The outer wall of the mold block 3 is provided with a groove 23 corresponding to the clamping head 22 and the elastic plate 21. The outlet of the groove 23 is provided with a beveled part corresponding to the clamping head 22. The cross-section of the end of the clamping head 22 that is inserted into the groove 23 is trapezoidal. The side cover plate 8 is detachably clamped to the mold block 3 through the elastic plate 21, the clamping head 22 and the groove 23.

[0021] Please see Figure 1-7 When the side cover plate 8 and the mold block 3 are closed, the clamping head 22 first forms a compression with the inclined surface. The clamping head 22 will then be connected to the elastic plate 21 and tilt upwards. After the side cover plate 8 and the mold block 3 are closed, the elastic plate 21 allows the clamping head 22 to be inserted into the slot 23, thus locking the two together. Conversely, when the side cover plate 8 and the mold block 3 are pushed open by the cylinder 25, the clamping head 22 and the inclined surface of the slot 23 are pressed against each other, and the clamping head 22 will be pressed upwards again, thus opening the side cover plate 8 and the mold block 3.

[0022] When in use, when the output end of cylinder 4 extends to its maximum stroke, the end of the extrusion punch 7 is flush with the side wall of the side sealing plate 20, thereby closing the left opening of the heterogeneous heat dissipation element slot 11. The side cover plate 8 is driven by cylinder 2 5 to fit against the right side of the mold block 3. The closing punch 10 is inserted into the right opening of the anisotropic heat dissipation element groove 11 and closes it. The elastic plate 21 is tilted up so that the clip 22 is locked in the slot 23, thereby achieving the locking between the side cover plate 8 and the mold block 3. Molten metal is poured into the anisotropic heat dissipation element groove 11 through the pouring hole 19. The mold block 3 is provided with an upper fan-shaped cooling cavity 13, a lower fan-shaped cooling cavity 14 and a central cooling cavity 15. The cold water inlet 16 and the cooling water outlet 17 are connected to the external circulating cooling water equipment, so that the cooling water can flow in the cavity mentioned above, which can accelerate the cooling and solidification of the molten metal. Then, the side cover plate 8, protruding block 9 and closing punch 10 are pushed open by cylinder 2 5. The extrusion punch 7 is driven by cylinder 1 4 to penetrate into the groove 11 of the irregular heat dissipation element. The extrusion punch 7 can push and extrude the body 12 of the irregular heat dissipation element from the groove 11. This process can realize the convenient and quick extrusion and removal of the body 12 of the irregular heat dissipation element, solving the problem that the traditional irregular heat dissipation element is difficult to remove.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
