Description

Technical Field

[0001] This utility model relates to the field of rubber vulcanizing machine technology, specifically to a cooling device for a rubber vulcanizing machine. Background Technology

[0002] Rubber vulcanization is a chemical reaction between rubber molecules and a vulcanizing agent, which transforms the rubber from a linear structure to a network structure, thereby changing the physical and chemical properties of the rubber, such as improving its strength, elasticity, wear resistance, and aging resistance. A rubber vulcanizing machine is a specialized piece of equipment that can provide the temperature, pressure, and time required for vulcanization.

[0003] During the vulcanization process of rubber products, the molds in rubber vulcanizing machines release a large amount of heat, and cooling devices are often used to cool the molds. While existing cooling devices can achieve basic cooling functions, they are mostly fixed in place and lack flexible height adjustment. In the working process of the rubber vulcanizing machine, the molds often need to move up and down. When the mold moves downwards, the existing cooling devices cannot adjust their height accordingly, causing a change in the relative height between the cooling device's outlet and the mold. They cannot always maintain the same horizontal plane, which directly results in the cooling airflow from the outlet not being able to accurately and efficiently act on the mold surface, thus greatly weakening the cooling efficiency. Therefore, improvements are needed. Utility Model Content

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1 to 5As shown, this utility model provides a cooling device for a rubber vulcanizing machine, including a base plate 1, a support platform 2 fixedly connected to the middle of the top of the base plate 1, a support rod 3 fixedly connected to the top of the support platform 2, a rectangular plate 4 fixedly connected to the top of the support rod 3, a dual-axis motor 5 fixedly connected to the top of the rectangular plate 4, a rotating shaft 6 fixedly sleeved at the other end of the output shaft of the dual-axis motor 5, a rotating block 7 fixedly sleeved on the outer surface of the rotating shaft 6, a round shaft 8 fixedly sleeved inside the other end of the rotating block 7, a lifting plate 9 movably connected to the outer surface of the round shaft 8, and two fans 10 fixedly installed at the bottom of the lifting plate 9. Each of the two fans 10 has an air intake 11 fixedly connected to its outer side and an air outlet 12 fixedly connected to its inner side.

[0027] When the dual-axis motor 5 is running, the two rotating shafts 6 will drive the two rotating blocks 7 to rotate, which in turn will cause the two round shafts 8 to rotate and drive the two lifting plates 9 to move downward, thereby causing the two fans 10 to move downward, so that the two air outlets 12 can always be at the same level as the mold, thus achieving the purpose of efficient cooling of the mold.

[0028] Among them, connecting blocks 13 are fixedly installed at the front and rear of the two fans 10, and round rods 14 are movably sleeved inside the connecting blocks 13. The bottom of the round rods 14 is fixedly connected to the top of the base plate 1.

[0029] The design of the connecting block 13 and the round rod 14 serves to limit the movement of the two fans 10, ensuring that the two fans 10 can move downwards stably.

[0030] The support platform 2 is equipped with a pneumatic cylinder 15, the top of which passes through the support platform 2 and extends to the top of the support platform 2 and is fixedly connected to a mounting plate 16. The top of the mounting plate 16 is fixedly connected to a first electric heating plate 17.

[0031] When the pneumatic cylinder 15 is running, it will drive the mounting plate 16 and the first electric heating plate 17 to move upward.

[0032] The inner surface of the mounting plate 16 is movably connected to the outer surface of the support rod 3, and the inner surface of the mounting plate 16 is smooth.

[0033] This design allows the mounting plate 16 to move more smoothly on the surface of the support rod 3.

[0034] The bottom of the rectangular plate 4 is fixedly connected to a second heating plate 18, the second heating plate 18 having the same dimensions as the first heating plate 17.

[0035] The combination of the second heating plate 18 and the first heating plate 17 enables the heating and extrusion of the mold.

[0036] The two fans 10 are fixedly connected to the outside of a cooling box 19. A cooling plate 20 is movably installed inside the cooling box 19, and a handle 21 is fixedly connected to the top of the cooling plate 20.

[0037] This design makes it easy for operators to remove and replace the cooling plate 20 by pulling the handle 21.

[0038] The top of the lifting plate 9 is fixedly connected to a drive motor 22, and the other end of the output shaft of the drive motor 22 is fixedly sleeved with a drive shaft 23. A rotating rod 24 is fixedly sleeved on the outer surface of the drive shaft 23.

[0039] When the drive motor 22 is running, it will cause the drive shaft 23 to drive the rotating rod 24 to rotate.

[0040] The inner surface of the rotating rod 24 is movably connected to a cylindrical block 25, the bottom of the cylindrical block 25 is fixedly connected to a pin 26, the outer surface of the pin 26 is movably connected to the inner surface of the cooling box 19, and the outer side of the pin 26 penetrates the cooling plate 20 and extends into the interior of the cooling plate 20.

[0041] The two cylindrical blocks 25 move toward each other, which will cause the two pins 26 to move toward each other. When the two pins 26 move to the inside of the two cooling plates 20, the fixing effect on the two cooling plates 20 will be released, making it easier to quickly and efficiently move the two cooling plates 20.

[0042] The cooling box 19 is fitted with a connecting pipe 27, which is circular in shape.

[0043] The design of the connecting pipe 27 serves to assist the air intake 11 in drawing in outside air.

[0044] There are four round rods 14, and the four round rods 14 are symmetrical about the center of the base plate 1.

[0045] The design of four round rods 14 provides a better limiting effect for the two fans 10.

[0046] Working principle and usage process of this utility model:

[0047] During the vulcanization process of rubber products, the mold releases a lot of heat, so it needs to be cooled down. At this time, starting two fans 10 will cause two air inlets 11 to draw in outside air through two connecting pipes 27. The air enters the interior of two cooling boxes 19, is cooled by two cooling plates 20, and then is discharged from two air outlets 12 to cool the mold.

[0048] When the mold moves downward, the relative height between the air outlet 12 and the mold changes, making them no longer on the same horizontal plane. At this time, the dual-axis motor 5 is started, which will cause the two rotating shafts 6 to drive the two rotating blocks 7 to rotate, which in turn causes the two round shafts 8 to rotate and drive the two lifting plates 9 to move downward, thereby causing the two fans 10 to move downward, so that the two air outlets 12 can always be on the same horizontal plane as the mold, achieving the purpose of efficient cooling of the mold.

[0049] When the cooling effect of the cooling plate 20 on the air weakens, it needs to be replaced. At this time, starting the two drive motors 22 will cause the two drive shafts 23 to drive the two rotating rods 24 to rotate. In turn, the rotating rods 24 rotate and squeeze the two cylindrical blocks 25 and the two pins 26 to move towards each other. When the two pins 26 move to the inside of the two cooling plates 20, the fixing effect on the two cooling plates 20 will be released. At this time, by pulling the two handles 21 upward, the purpose of quickly replacing the two cooling plates 20 can be achieved, which improves convenience.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
