Description

Technical Field

[0001] The present invention relates to the technical field of heat insulation plates, and more specifically, to a heat insulation plate for a vulcanizer and a manufacturing method thereof. Background Art

[0002] The heat insulation plate of the vulcanizer is used to block the heat transfer between the heating plate and the vulcanizer frame and can withstand the clamping pressure of the vulcanizer. Currently, the heat insulation plate is made by mixing and pressing reinforcing materials such as glass fiber and resin. This kind of heat insulation plate has poor heat resistance. Under the condition of being frequently subjected to the clamping pressure of the vulcanizer, the existing heat insulation plate has a low service life and is prone to aging, and has a high thermal conductivity. During the vulcanization process of the product, it needs to be heated frequently to maintain the required vulcanization temperature, resulting in waste of resources.

[0003] In order to improve the service life of the heat insulation plate, enhance the strength of the heat insulation plate, reduce the thermal conductivity of the heat insulation plate, and reduce production costs, therefore, a heat insulation plate for a vulcanizer and a manufacturing method thereof are proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a heat insulation plate for a vulcanizer and a manufacturing method thereof to solve the problems raised in the above background art.

[0005] To solve the above technical problems, one of the purposes of the present invention is to provide a heat insulation plate for a vulcanizer, including a cover plate. The two cover plates are vertically distributed up and down. A plurality of support components are arranged between the cover plates, and through holes corresponding to the support components are arranged on the surface of the cover plate;

[0006] The support component includes a support column arranged between the cover plates. A through groove is provided on the surface of the support column, and a support sleeve is arranged in the through groove. The support sleeve is adapted to the through groove. The support sleeve is used to bear the clamping force of the vulcanizer. Gaskets are arranged on the surfaces at both ends of the support column. The surface of the gasket is stepped. The gasket is adapted to the through hole. The support column and the gasket are fixedly connected by fastening bolts. Aerogel felt is filled around the support component to reduce heat transfer between the cover plates through the aerogel felt.

[0007] As a further improvement of this technical solution, the support components are annularly distributed around the center of the cover plate in an array manner. The support components improve the overall support strength of the cover plate through the annular array distribution.

[0008] As a further improvement of this technical solution, the support sleeve is made of zirconia material, and zirconia has the characteristics of high strength and low thermal conductivity.

[0009] As a further improvement of this technical solution, the gasket in the cover plate and the support component is fixed by welding, and the gasket and the cover plate form a plane through welding.

[0010] A second object of the present invention is to provide a vulcanizer and a manufacturing method thereof, including the heat insulation plate for a vulcanizer described in any one of the above, comprising the following steps:

[0011] S1. Place the support sleeve at the through groove of the support column for adaptation. After the adaptation is completed, fix the gasket at both ends of the support column through fastening bolts to complete the assembly of the support component;

[0012] S2. Fix the gasket at one end of the support component and the mask by welding. Then cut the aerogel felt into round pieces and reserve the mounting holes on the support component. Put the aerogel felt on the surface of the support component, cover the other mask on the surface of the aerogel felt, and fix the mask and the gasket at the other end of the support component by welding.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The mask is used as the contact surface of the heat insulation plate. The mask has good temperature resistance and can avoid deformation in a high-temperature environment. By providing a support component between the masks, the support component is used to enhance the clamping pressure of the vulcanizer borne by the mask and improve the service life of the mask. By reducing the heat conduction rate of the surface temperature of the mask through the support component, the heating energy and fuel required during the operation of the vulcanizer are reduced, thereby reducing the production cost. Aerogel felt is filled around the support component, and the aerogel felt is used to reduce the heat transfer between the masks, maintain the vulcanization temperature required for product vulcanization, and prevent the loss of heat energy, thus saving resources.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The heat insulation board of the vulcanizer is used to block the heat transfer between the heating plate and the vulcanizer frame and can withstand the clamping pressure of the vulcanizer. Now the heat insulation board is made by mixing and pressing the reinforcing materials of glass fiber and resin. This kind of heat insulation board has poor heat resistance. Under the state of often being subjected to the clamping pressure of the vulcanizer, the existing heat insulation board has a low service life and is easy to age, and has a high thermal conductivity. During the vulcanization process of the product, it needs to be heated frequently to maintain the temperature required for vulcanization, resulting in waste of resources. In order to improve the service life of the heat insulation board, reduce the thermal conductivity of the heat insulation board, and reduce production costs, therefore, a heat insulation board for a vulcanizer and its manufacturing method are proposed.

[0026] One of the purposes of the present invention is to provide a heat insulation board for a vulcanizer, which includes a cover plate 100. Two cover plates 100 are distributed vertically up and down. A plurality of support assemblies 200 are arranged between the cover plates 100. Through holes corresponding to the support assemblies 200 are provided on the surface of the cover plate 100. Refer to Figure 1 , Figure 5 and Figure 6 As shown, the support assembly 200 includes a support column 201 arranged between the cover plates 100. A through groove is provided on the surface of the support column 201. A support sleeve 202 is arranged in the through groove. The support sleeve 202 is adapted to the through groove. The support sleeve 202 is used to bear the clamping force of the vulcanizer. Gaskets 203 are provided on the surfaces at both ends of the support column 201. The surfaces of the gaskets 203 are stepped and are adapted to the through holes. The support column 201 and the gaskets 203 are fixedly connected by fastening bolts. The cover plates 100 are supported by the support sleeve 202. The gaskets 203 in the cover plates 100 and the support assembly 200 are fixed by welding. The gaskets 203 and the cover plates 100 form a plane through welding.

[0027] Since the support sleeve 202 is made of zirconia material, the Mohs hardness grade of zirconia is 8 - 8.5, which has the characteristic of high hardness. When supporting between the cover plates 100, the support sleeve 202 can bear the clamping pressure of the vulcanizer. At the same time, the thermal conductivity of the support sleeve 202 is usually between 2 - 3 W / m·K, which is relatively low compared with other common heat-conducting materials, enabling the heat insulation board to have a high-strength supporting effect while reducing the thermal conductivity of the heat insulation board. Refer to Figure 4 and Figure 5As shown, the support component 200 is surrounded by aerogel felt 300. Use a ruler or template to mark the required shape on the surface of the aerogel felt 300, ensuring that the marks are clear and accurate. Press a blade knife or cutting knife against the marked line and cut along the marked line. By cutting the aerogel felt 300 into a disc with the same diameter and reserving the installation holes for the support component 200 on the surface of the aerogel felt 300, the density of the aerogel felt 300 is very low, which makes it a lightweight thermal insulation material. Its thermal conductivity is usually between 0.015 - 0.030 W / (m·K), which is dozens of times that of traditional thermal insulation materials such as glass fiber and rock wool;

[0028] By reducing the heat transfer between the masking plates 100 through the aerogel felt 300, heat energy is dissipated, thereby maintaining the required vulcanization temperature, avoiding excessive or too small temperature, ensuring that the rubber product is vulcanized at the correct temperature and time, and thus obtaining a better vulcanization effect.

[0029] Using the masking plate 100 as the contact surface of the heat insulation plate, the masking plate 100 has good temperature resistance and avoids deformation in a high-temperature environment. By providing a support component 200 between the masking plates 100, the support component 200 is used to enhance the clamping pressure of the vulcanizer on the masking plate 100. By the support component 200, the heat conductivity of the surface temperature of the masking plate 100 is reduced, reducing the heating energy and fuel required during the operation of the vulcanizer, thereby reducing production costs. Fill the aerogel felt 300 around the support component 200, and the aerogel felt 300 is used to reduce the heat transfer between the masking plates 100 and prevent the loss of heat energy, thus saving resources.

[0030] Since the surface of the heat insulation plate needs to bear the clamping pressure of the vulcanizer, in order to improve the structural stability of the heat insulation plate and avoid deformation of the surface of the heat insulation plate, which affects the use effect, refer to Figure 1 and Figure 4 As shown, the support components 200 are distributed in a circular array around the center of the masking plate 100. The support components 200 improve the overall support strength of the masking plate 100 through the circular array distribution. The support components 200 disperse the pressure load between them, thereby improving the overall stability of the heat insulation plate.

[0031] In order to improve the support strength of the heat insulation plate, refer to Figure 6 As shown, the support sleeve 202 is made of zirconia. Zirconia has the characteristics of high strength and low heat conductivity. Since zirconia has a very high hardness, usually 8 - 8.5 in the Mohs hardness scale, it is harder than many metals and other ceramic materials. Therefore, by using the support sleeve 202 to support the inside of the heat insulation plate, the service life of the heat insulation plate is guaranteed.

[0032] The second object of the present invention is to provide a vulcanizer and its manufacturing method, including the heat insulation plate for the vulcanizer according to any one of the above, and including the following steps:

[0033] S1. Place the support sleeve 202 at the through groove of the support column 201 for adaptation. After the adaptation is completed, fix the gasket 203 to both ends of the support column 201 through fastening bolts to complete the assembly of the support assembly 200;

[0034] S2. Weld and fix the gasket 203 at one end of the support assembly 200 to the mask 100. Then cut the aerogel felt 300 into circular pieces and reserve the mounting holes on the support assembly 200. Put the aerogel felt 300 on the surface of the support assembly 200, cover the other mask 100 on the surface of the aerogel felt 300, and weld and fix the mask 100 to the gasket 203 at the other end of the support assembly 200.

[0035] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
