Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, and in particular to a vulcanizing machine with a rapid heating structure. Background Technology

[0002] A vulcanizing machine is a machine that vulcanizes various rubber and plastic materials. It has functions such as timed mold locking, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. Vulcanizing machines are divided into three types: electric heating, steam heating, and heat transfer oil heating. During the use of a vulcanizing machine, a heating device is needed to provide the required pressure and temperature to the material.

[0003] However, when vulcanizing materials, heating is done directly through two heating plates, which can easily cause heat to be lost to the outside. This can lead to uneven temperature distribution on the surface of the heating plates and on different parts of the material. Some parts of the material may be cold due to rapid heat loss and cannot be fully vulcanized. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vulcanizing machine with a rapid heating structure. The vulcanizing area is enclosed by a cover, reducing heat loss to the outside and allowing more heat to be used in the vulcanization process of the material. Furthermore, with the cooperation of the fan and fixed plates, the hot air circulates between the two fixed plates, achieving uniform and rapid heating.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vulcanizing machine with a rapid heating structure includes a base plate, an mounting plate fixedly connected to the upper end of the base plate, two first hydraulic cylinders mounted on the lower end of the mounting plate, the output ends of the two first hydraulic cylinders being fixedly connected to a cover, a second hydraulic cylinder mounted on the inner top of the cover, an upper heating plate fixedly connected to the output end of the second hydraulic cylinder, an upper mold fixedly connected to the lower end of the upper heating plate, two lower heating plates provided on the upper end of the base plate, and a lower mold provided on the upper end of each of the two lower heating plates, fixing plates fixedly connected to the inner walls of both sides of the cover, both fixing plates being hollow inside, and multiple through holes opened on opposite sides of the two fixing plates, a fan mounted on the upper end of the mounting plate, the air inlet of the fan communicating with the interior of one of the fixing plates through an air inlet pipe, and the air outlet of the fan communicating with the interior of the other fixing plate through an air outlet pipe.

[0008] Preferably, a rotating rod is rotatably connected between the inner walls of the two sides of the movable groove, and a first gear is fixedly connected to the outer wall of the rotating rod. The first gear meshes with a rack. A first motor is installed on the outer wall of the base plate. The output shaft of the first motor extends into the movable groove and is fixedly connected to one end of the rotating rod.

[0009] Preferably, each of the two lower heating plates has a first sliding groove at its upper end, an electric telescopic rod is installed on the inner wall of each of the two first sliding grooves, and a first slider is fixedly connected to the telescopic end of each of the two first electric telescopic rods. Each of the two lower molds has a second sliding groove, and a second slider is slidably connected to the inner wall of each of the two second sliding grooves.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The structure includes a first hydraulic cylinder and a cover, which allows the cover to move down and contact the upper part of the base plate to form a relatively sealed space, thereby reducing heat loss.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A vulcanizing machine with a rapid heating structure includes a base plate 1. A mounting plate 2 is fixedly connected to the upper end of the base plate 1. Two first hydraulic cylinders 3 are mounted on the lower end of the mounting plate 2. The output ends of the two first hydraulic cylinders 3 are jointly fixedly connected to a cover 4. By setting the cover 4, a relatively sealed space can be formed, greatly reducing the loss of internal heat to the external environment, allowing more heat to be concentrated in the vulcanizing area, reducing heat waste, and facilitating rapid heating. A second hydraulic cylinder 5 is installed at the inner top of the cover 4. The output end of the second hydraulic cylinder 5 is fixedly connected to an upper heating plate 6. The lower end of the upper heating plate 6 is fixedly connected to an upper mold 7. The upper end of the base plate 1 is provided with two lower heating plates 8. The upper end of each of the two lower heating plates 8 is provided with a lower mold 9. The upper end of the base plate 1 is provided with a moving groove 10. The inner walls of both sides of the moving groove 10 are fixedly connected to a guide rod 11. The outer wall of the guide rod 11 is slidably connected to a rack 12. The upper end of the rack 12 is fixedly connected to two moving blocks 13. The upper ends of the two moving blocks 13 are fixedly connected to the lower ends of the corresponding lower heating plates 8.

[0023] The inner walls of the two sides of the moving groove 10 are rotatably connected to a rotating rod 14. The outer wall of the rotating rod 14 is fixedly connected to a first gear 15. The first gear 15 meshes with a rack 12. Through the cooperation of the rack 12 and the first gear 15, the two lower molds 9 can be moved. In this way, while processing one of the lower molds 9, the other lower mold 9 can be loaded and unloaded, which shortens the downtime of the vulcanizing machine and allows the vulcanizing machine to maintain a suitable working temperature range for a longer period of time, thus effectively improving the heating efficiency. The outer wall of the base plate 1 is equipped with a first motor 16, which is a servo motor. The output shaft of the first motor 16 extends into the interior of the moving groove 10 and is fixedly connected to one end of the rotating rod 14. The upper ends of the two lower heating plates 8 are each provided with a first sliding groove 17. The inner walls of the two first sliding grooves 17 are each equipped with an electric telescopic rod 18. The telescopic ends of the two electric telescopic rods 18 are each fixedly connected to a first slider 19.

[0024] Each of the two lower molds 9 has a second slide groove 20, and a second slider 21 is slidably connected to the inner wall of each of the two second slide grooves 20. Each of the two first sliders 19 cooperates with the corresponding second slider 21. The upper ends of the two lower heating plates 8 and the lower ends of the two lower molds 9 have rotating grooves 22. A rotating shaft 23 is rotatably connected between the inner walls on both sides of each rotating groove 22. A second gear 24 is fixedly connected to the outer wall of each rotating shaft 23. Each pair of cooperating second gears 24 mesh with each other. Through the meshing action of the two second gears 24, the lower mold 9 can rotate to a certain angle. Then, the electric telescopic rod 18 is activated, so that the first slider 19 enters the second slide groove 20 and pushes the second slider 21 upward along the second slide groove 20, thereby pushing out the material for easy removal. A second motor 25 is installed on the outer wall of each of the two lower heating plates 8. Both second motors 25 are servo motors.

[0025] The output shafts of the two second motors 25 extend into the corresponding rotating slots 22 and are fixedly connected to one end of the corresponding rotating shafts 23. Fixing plates 26 are fixedly connected to the inner walls of both sides of the cover 4. Both fixing plates 26 are hollow, and multiple through holes are opened on opposite sides of each fixing plate 26. A fan 27 is installed on the upper end of the mounting plate 2. The fan 27 is a circulating fan. The air inlet of the fan 27 is connected to the interior of one of the fixing plates 26 through an air inlet pipe 28, and the air outlet of the fan 27 is connected to the interior of the other fixing plate 26 through an air outlet pipe 29. The fan 27 causes hot air to circulate continuously between the two fixing plates 26. Through the multiple through holes on opposite sides of the fixing plates 26, the hot air can be evenly distributed inside the cover 4, fully contacting the upper heating plate 6, the lower heating plate 8, and the material. This ensures that the material receives uniform heat transfer in all parts during the vulcanization process, effectively avoiding local overheating or overcooling and achieving rapid heating.

[0026] In this utility model, when in use, the first hydraulic cylinder 3 is first activated. The extension of the first hydraulic cylinder 3 will cause the cover 4 to drop, thereby sealing the vulcanization area, reducing the loss of internal heat to the external environment, and improving the thermal efficiency of the entire heating system. Then, the second hydraulic cylinder 5 is activated. The second hydraulic cylinder 5 will extend and push the upper mold 7 to move downward and close with the lower mold 9, so as to vulcanize the material placed on the lower mold 9.

[0027] During vulcanization, the upper heating plate 6 and the lower heating plate 8 can be activated for heating. At the same time, the blower 27 can be activated to make the hot air continuously circulate between the two fixed plates 26. The hot air first enters the interior of one fixed plate 26 through the air inlet pipe 28, and then flows out from the through hole of the fixed plate 26, and is evenly distributed inside the cover 4, making full contact with the upper heating plate 6, the lower heating plate 8 and the material to heat the material. After that, the hot air enters the interior of the other fixed plate 26 through the through hole, and returns to the blower 27 through the air outlet pipe 29. This cycle is repeated to realize the recycling and even distribution of hot air, ensuring that the material can receive uniform heat transfer in all parts during the vulcanization process, effectively avoiding local overheating or overcooling, and thus achieving rapid heating.

[0028] After vulcanization, the first motor 16 is started, causing the rotating rod 14 to rotate, which in turn causes the first gear 15 to rotate. The rotation of the first gear 15 causes the rack 12, which meshes with it, to slide along the guide rod 11 in the moving groove 10. The rack 12 drives the lower heating plate 8 and the lower mold 9 to move through the moving block 13. In this way, when vulcanizing one of the lower molds 9, the other lower mold 9 can be moved to a position that is easy to pick up and put down the material, reducing the downtime of the vulcanizing machine and enabling the vulcanizing machine to maintain a suitable working temperature range for a longer period of time, thus improving heating efficiency.

[0029] When material needs to be retrieved, the second motor 25 can be started, causing the rotating shaft 23 to rotate, which in turn causes the second gear 24 to rotate. Through the meshing of the second gear 24, the lower mold 9 is rotated to a certain angle. Then, the electric telescopic rod 18 is started, and the electric telescopic rod 18 extends, causing the first slider 19 to enter the second slide groove 20 and push the second slider 21 upward along the second slide groove 20, thereby pushing the material out. This makes it convenient for workers to retrieve the material and reduces the safety risks of burns and scratches.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
