Technical Field
[0001] This utility model relates to the field of vulcanized rubber processing technology, specifically to a vulcanized rubber extrusion die with a cooling structure. Background Technology
[0002] Vulcanized rubber is a thermosetting elastomer material in which rubber molecules form a three-dimensional network structure through a vulcanization process (crosslinking reaction). Its performance is significantly better than that of raw rubber, and it is widely used in industrial and consumer products. Vulcanized rubber extrusion molds are key tools used in the extrusion molding process of vulcanized rubber. The extrusion molds shape the rubber material into profile semi-finished products with specific cross-sectional shapes.
[0003] Existing vulcanized rubber extrusion molds lack cooling structures and require the installation of water tanks or similar structures to cool and shape the extruded vulcanized rubber. However, directly introducing the extruded vulcanized rubber into the water tank can cause cracking due to the large temperature difference. Therefore, a vulcanized rubber extrusion mold with a cooling structure is proposed. The vulcanized rubber extruded from the mold body enters the first connecting sleeve and is first air-cooled by the first heat dissipation component, and then enters the second connecting sleeve and is water-cooled by the second heat dissipation component. This provides good cooling effect and prevents the vulcanized rubber from cracking. Utility Model Content

The vulcanized rubber extruded from the extrusion die body enters the first connecting sleeve and is first air-cooled by the first heat dissipation component, and then enters the second connecting sleeve and is water-cooled by the second heat dissipation component. The cooling effect is good and will not cause the vulcanized rubber to crack.

An exhaust fan is installed at both ends of the ventilation box by a mounting bracket. The second heat dissipation component includes a water collection pipe disposed at the top of the second connecting sleeve. Water inlet pipes are welded at equal intervals at the bottom of the water collection pipe. A nozzle is connected to the bottom end of the water inlet pipe inside the second connecting sleeve by a threaded groove.
[0006] By adopting the above technical solution, the vulcanized rubber extruded from the extrusion die body passes through the first connecting sleeve and the second connecting sleeve in sequence. The exhaust fan operates to air-cool the vulcanized rubber in the first connecting sleeve, and the clean water or cooling water in the water collection pipe flows into the water inlet pipe and is sprayed out through the nozzle to water-cool the vulcanized rubber in the second connecting sleeve.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] The vulcanized rubber extruded from the extrusion die body enters the first connecting sleeve and is first air-cooled by the first heat dissipation component, then enters the second connecting sleeve and is water-cooled by the second heat dissipation component. This provides good cooling and prevents the vulcanized rubber from cracking. Figure 1-4 As shown, the present invention provides a vulcanized rubber extrusion mold with a cooling structure, including an extrusion mold body 1, a first connecting sleeve 2 and a second connecting sleeve 3. A second heat dissipation component 5 is provided on the top of the second connecting sleeve 3. The second connecting sleeve 3 is located at one end of the extrusion mold body 1.

The bottom of the water collection pipe 501 is welded with an inlet pipe 502 at equal intervals. The bottom end of the inlet pipe 502 located inside the second connecting sleeve 3 is connected to a nozzle 503 through a threaded groove.
[0018] In use, the vulcanized rubber extruded from the extrusion die body 1 passes through the first connecting sleeve 2 and the second connecting sleeve 3 in sequence. The exhaust fan 402 operates to air-cool the vulcanized rubber in the first connecting sleeve 2. The clean water or cooling water in the water collection pipe 501 flows into the water inlet pipe 502 and is sprayed out through the nozzle 503 to water-cool the vulcanized rubber in the second connecting sleeve 3.
[0019] For example, such as Figure 3As shown, the present invention also includes a through slot 403 that is equidistantly provided on both sides of the first connecting sleeve 2 inside the ventilation box 401, and a dustproof net 404 that is fixed inside the ventilation box 401 on one side of the exhaust fan 402 by bolts.
[0020] When in use, the opening of the through slot 403 facilitates the extraction of gas from the first connecting sleeve 2 when the exhaust fan 402 is working, and the dustproof net 404 can prevent dust and other objects from entering the ventilation box 401.
[0021] For example, such as Figure 4 As shown, the present invention also includes a water inlet pipe 502 that passes through the second connecting sleeve 3, and a flange ring 504 that is fixedly sleeved on the outside of the water inlet pipe 502. The flange ring 504 is fixed to the top of the second connecting sleeve 3 by bolts.
[0022] In use, the water inlet pipe 502 that passes through the second connecting sleeve 3 can be fixed by using bolts through the flange ring 504.
[0023] For example, such as Figure 4 As shown, the present invention also includes a valve 506 connected to the top of the water collection pipe 501 via a pipe, and a sealing ring 505 sleeved on the outer side of the bottom of the flange ring 504 of the water inlet pipe 502.
[0024] When in use, open valve 506 to allow clean water or cooling water to flow into water collection pipe 501, and seal ring 505 seals between flange ring 504 and second connecting sleeve 3.

[0026] During use, the opening of the drain hole 6 facilitates the discharge of clean water or cooling water from the second connecting sleeve 3.
[0027] For example, such as Figure 2 As shown, the present invention also includes a first external threaded mating ring 201 welded to one end of the first connecting sleeve 2 near the extrusion die body 1, and a second mating threaded groove 202 opened on the inner side of the first connecting sleeve 2.
[0028] In use, the first external threaded mating ring 201 is screwed into the first mating thread groove 101 to fix the first connecting sleeve 2 to one end of the extrusion die body 1, and the second external threaded mating ring 301 is screwed into the second mating thread groove 202 to fix the second connecting sleeve 3 to one end of the first connecting sleeve 2.
[0029] In use, the extrusion die body 1 is fixed to the discharge port of the vulcanizing rubber extrusion equipment with bolts. The first external threaded mating ring 201 is screwed into the first mating thread groove 101, which can fix the first connecting sleeve 2 to one end of the extrusion die body 1. The second external threaded mating ring 301 is screwed into the second mating thread groove 202, which can fix the second connecting sleeve 3 to one end of the first connecting sleeve 2. Connect the exhaust fan 402 to an external power source using a power cord. The vulcanized rubber extruded from the extrusion die body 1 enters the first connecting sleeve 2. Turn on the exhaust fan 402 to draw the gas in the first connecting sleeve 2 into the ventilation box 401 through multiple channels 403 and discharge it through the dustproof net 404, thereby accelerating the gas flow in the first connecting sleeve 2 and cooling the vulcanized rubber that has entered the first connecting sleeve 2. Connect valve 506 to the water supply equipment. The air-cooled vulcanized rubber in the first connecting sleeve 2 enters the second connecting sleeve 3. Open valve 506 to allow clean water or cooling water to flow into the water collection pipe 501, and then distribute it to multiple water inlet pipes 502 and spray it out through nozzles 503. This can cool the air-cooled vulcanized rubber with water. The cooled clean water or cooling water flows out through drain hole 6.
