Description

Technical Field

[0001] This utility model belongs to the field of aluminum profile extrusion die technology, specifically relating to a high-efficiency cooling aluminum profile extrusion die structure. Background Technology

[0002] Aluminum products have a series of excellent properties, such as high strength, good weather resistance, and low density. They are often used to make radiator parts or exterior decorative parts. In the production process of aluminum profiles, extrusion dies are needed to shape the aluminum profiles. Aluminum profile extrusion dies are key tools in aluminum profile production. They are used to extrude heated aluminum rods (billets) under high pressure to obtain the required cross-sectional shape. Due to the plastic deformation and friction of the metal, the temperature of the mold will rise rapidly. Excessive temperature will not only accelerate the wear of the mold and reduce its service life, but may also lead to a decline in the surface quality of the aluminum profile, or even defects such as deformation and cracks. Existing cooling solutions often only use a single air cooling or liquid cooling mode, failing to effectively combine the advantages of both, resulting in unsatisfactory cooling effects. To address this, we designed a high-efficiency cooling aluminum profile extrusion die structure to provide an alternative technical solution to the aforementioned technical problems. Utility Model Content

[0003] The purpose of this invention is to provide a highly efficient cooling aluminum profile extrusion die structure to solve the problems mentioned in the background art during the use of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cooling aluminum profile extrusion die structure, including an aluminum profile extrusion die, an annular heat dissipation box is provided on the outer side of the aluminum profile extrusion die, a detachable annular cover is provided on one side of the annular heat dissipation box, a top mounting block is provided at the top of the annular cover and inside the annular heat dissipation box, a cooling fan is fixed inside the top mounting block, and a heat dissipation mechanism is provided inside the annular heat dissipation box.

[0005] Preferably, the heat dissipation mechanism includes an injection port, and both ends of the annular cover are fixed with injection ports. The bottom of the injection port is connected to a distribution box through a pipe. Multiple annular heat dissipation pipes are evenly distributed and fixed on the outer side of the two distribution boxes. Multiple heat dissipation copper fins are evenly distributed on the outer side of the annular heat dissipation pipes and inside the annular heat dissipation box.

[0006] Preferably, the heat dissipation copper fin is located near one end of the annular cover and is fixedly connected to the annular cover. A dovetail slider is fixed to the inner side of the heat dissipation copper fin, and a dovetail groove is provided inside the annular heat dissipation box. The heat dissipation copper fin and the annular heat dissipation box are slidably connected through the dovetail slider and the dovetail groove.

[0007] Preferably, the liquid filled inside the annular heat dissipation pipe is coolant or liquid nitrogen.

[0008] Preferably, the bottom of the annular heat sink is provided with a plurality of bottom ventilation holes evenly distributed inside.

[0009] Preferably, a sealing ring is provided at one end of the annular heat sink near the annular cover, and the annular cover and the annular heat sink are fixed together by bolts.

[0010] Preferably, the top mounting block is internally slidably connected to a dovetail limiting block. The dovetail limiting block is located near one end of the annular heat sink and is fixedly connected to the annular heat sink. Two transverse limiting bolts are provided at the end of the annular heat sink away from the dovetail limiting block.

[0011] Preferably, the top mounting block has a dovetail groove inside, and the dovetail limiting block is in clearance fit with the dovetail groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a cooling fan to allow outside air to enter the annular heat sink through bottom ventilation holes, enabling the air inside the annular heat sink to be exhausted to the outside. This air cooling reduces the temperature inside the annular heat sink, thereby lowering the temperature of the aluminum profile extrusion die. An external pump connected to the injection port injects coolant or liquid nitrogen, further reducing the temperature inside the copper heat sink through water cooling. This efficiently cools the aluminum profile extrusion die. By switching between water cooling and air cooling modes according to heat dissipation needs, the operating temperature of the aluminum profile extrusion die becomes more stable, extending its service life.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Reference Figure 1-7 A high-efficiency cooling aluminum profile extrusion die structure includes an aluminum profile extrusion die 1, an annular heat dissipation box 2 is provided on the outside of the aluminum profile extrusion die 1, a detachable annular cover 3 is provided on one side of the annular heat dissipation box 2, a top mounting block 4 is provided at the top of the annular cover 3 and inside the annular heat dissipation box 2, a cooling fan 5 is fixed inside the top mounting block 4, and a heat dissipation mechanism is provided inside the annular heat dissipation box 2. The heat dissipation mechanism includes a liquid injection port 7. Both ends of the annular cover 3 are fixed with liquid injection ports 7. The bottom of the liquid injection port 7 is connected to a distribution box 8 through a pipe. Multiple annular heat dissipation pipes 9 are evenly distributed and fixed on the outside of the two distribution boxes 8. Multiple heat dissipation copper fins 6 are evenly distributed on the outside of the annular heat dissipation pipes 9 and inside the annular heat dissipation box 2. The heat dissipation copper fin 6 is located near one end of the annular cover 3 and is fixedly connected to the annular cover 3. A dovetail slider is fixed on the inner side of the heat dissipation copper fin 6. A dovetail groove is opened inside the annular heat dissipation box 2. The heat dissipation copper fin 6 and the annular heat dissipation box 2 are slidably connected by the dovetail slider and the dovetail groove. The dovetail slider and the dovetail groove allow the heat dissipation copper fin 6 to slide inside the annular heat dissipation box 2, so that the heat dissipation copper fin 6 can slide into the annular heat dissipation box 2, so that the heat inside the annular heat dissipation box 2 can be transferred to the interior of the heat dissipation copper fin 6. The liquid inside the annular heat sink 9 is either coolant or liquid nitrogen. With the help of an external pump, the coolant or liquid nitrogen can be injected into the inlet 7, allowing the coolant and liquid nitrogen to circulate inside the annular heat sink 9, thus dissipating the heat inside the heat sink copper fin 6.

[0017] Multiple bottom ventilation holes 10 are evenly distributed inside the bottom of the annular heat sink 2, allowing outside air to enter the interior of the annular heat sink 2 through the bottom ventilation holes 10. Through the operation of the cooling fan 5, the air inside the annular heat sink 2 can be exhausted to the outside, thereby allowing the air inside the annular heat sink 2 to circulate.

[0018] Here, when the annular heat sink 2 is located outside the aluminum profile extrusion die 1, the heat inside the aluminum profile extrusion die 1 will enter the interior of the heat dissipation copper fin 6 through the annular heat sink 2. With the setting of the external pump, coolant or liquid nitrogen can be injected into the injection port 7, so that the coolant and liquid nitrogen can circulate inside the annular heat dissipation pipe 9, so that the heat inside the heat dissipation copper fin 6 can be dissipated, thereby effectively reducing the heat inside the aluminum profile extrusion die 1 and preventing the aluminum profile extrusion die 1 from being damaged due to high temperature.

[0019] A sealing ring 21 is provided at one end of the annular heat sink 2 near the annular cover 3. The annular cover 3 and the annular heat sink 2 are fixed together by bolts. The sealing ring 21 enables a sealed connection between the annular heat sink 2 and the annular cover 3, improving the sealing strength between the annular heat sink 2 and the annular cover 3. The bolts allow the annular cover 3 to be removed from one end of the annular heat sink 2. The top mounting block 4 has a dovetail limiting block 12 slidably connected inside. The dovetail limiting block 12 is close to one end of the annular heat sink 2 and is fixedly connected to the annular heat sink 2. Two transverse limiting bolts 11 are provided at one end of the annular heat sink 2 away from the dovetail limiting block 12. The transverse limiting bolts 11 pass through the interior of the dovetail limiting block 12 and are rotatably connected to the dovetail limiting block 12. The top mounting block 4 is threadedly connected to the transverse limiting bolts 11. The top mounting block 4 has a dovetail groove inside, and the dovetail limiting block 12 is fitted with the dovetail groove with a gap, so that the top mounting block 4 can slide vertically on the outside of the dovetail limiting block 12, and thus the top mounting block 4 can be removed from the outside of the dovetail limiting block 12.

[0020] Here, by operating the cooling fan 5, outside air can enter the interior of the annular heat sink 2, and outside air can come into contact with the heat sink copper fin 6, thereby allowing the air to carry the temperature inside the heat sink copper fin 6. By operating the cooling fan 5, the air inside the annular heat sink 2 can be exhausted to the outside, allowing the air inside the annular heat sink 2 to rotate, thereby allowing the aluminum profile extrusion die 1 to achieve a cooling effect. When it is necessary to disassemble the top mounting block 4, a tool is used to rotate the transverse limiting bolt 11. The rotation of the transverse limiting bolt 11 allows it to move out of the interior of the top mounting block 4, thereby allowing the top mounting block 4 to be disassembled outside the dovetail limiting block 12.

[0021] Working principle: Through the operation of the cooling fan 5, outside air can enter the interior of the annular heat sink 2, and the outside air can come into contact with the heat sink copper fin 6, thereby carrying away the temperature inside the heat sink copper fin 6. Through the operation of the cooling fan 5, the air inside the annular heat sink 2 can be exhausted to the outside, and the air inside the annular heat sink 2 can be rotated, thereby achieving the air cooling effect of the aluminum profile extrusion die 1. When the annular heat sink 2 is located outside the aluminum profile extrusion die 1, the heat inside the aluminum profile extrusion die 1 will enter the interior of the heat dissipation copper fin 6 through the annular heat sink 2. With the setting of the external pump, coolant or liquid nitrogen can be injected into the liquid injection port 7, so that the coolant and liquid nitrogen can circulate inside the annular heat dissipation pipe 9, so that the heat inside the heat dissipation copper fin 6 can be dissipated, thereby effectively reducing the heat inside the aluminum profile extrusion die 1 and preventing the aluminum profile extrusion die 1 from being damaged due to high temperature. When it is necessary to disassemble the top mounting block 4, a tool is used to rotate the transverse limiting bolt 11. The rotation of the transverse limiting bolt 11 allows it to move out of the interior of the top mounting block 4, thereby allowing the top mounting block 4 to be disassembled outside the dovetail limiting block 12.
