DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: a heat transfer element processing mold for a preheater that is easy to dissipate heat, comprising a base 1, a bearing plate 2, a cover plate 3, an outer mold sleeve 4, a first sealing pad 5, a second sealing pad 6, a fixing plate 7, an electric telescopic rod 8, a supporting plate 9, an inner mold sleeve 10, a limiting plate 11, a limiting plate 12, a limiting plate 13, a linkage plate 14, a reduction motor 15, a first cooling tube 16, a second cooling tube 17, an exhaust fan 18, a dustproof net 19 and a controller 20. When the heat transfer element processing mold for a preheater that is easy to dissipate heat is used, as shown in FIG. Figure 1 , Figure 3 and Figure 5 First, the material for processing the heat transfer element of the preheater can be put into the inner side of the outer mold sleeve 4 nested in the cover plate 3, and then the controller 20 embedded in the inner side of the rear upper end of the base 1 can be used to control the reduction motor 15 installed on the front side of the base 1 to operate, so that the reduction motor 15 drives the limit plate 13 connected thereto to rotate through the coupling. Since two limit plates 13 are arranged on the inner side of the base 1, the lower left rear side of the limit plate 13 is rotatably connected to the limit plate 11, and the middle rear side and the right front side of the limit plate 11 are rotatably connected to the bearing plate 2 The upper ends of the limiting plate 11 and the limiting plate 13 are both rotatably connected to the base 1, and a linkage plate 14 rotatably connected thereto is provided at the right rear side of the limiting plate 11. Therefore, the limiting plate 13 is driven by the linkage plate 14 to rotate in conjunction with the limiting plate 13 through the operation of the reduction motor 15, so that the limiting plate 11 drives the carrying plate 2 to perform annular rotation under the restriction of the limiting plate 12, thereby achieving the purpose of vibrating the processing material of the heat transfer element in the outer mold sleeve 4 to prevent the quality of the processed heat transfer element from being affected by the presence of holes;

[0028] like Figure 1 , Figure 2 and Figure 3 After the vibration of the heat transfer element processing material is completed, the controller 20 can be used to control the electric telescopic rod 8 nested inside the outer end of the carrier plate 2 to operate, so that the electric telescopic rod 8 drives the support plate 9 fixed thereon to descend, so that the support plate 9 drives the inner mold sleeve 10 fixed by screws therein to descend, until the inner mold sleeve 10 is nested and fits in the outer mold sleeve 4. Then, the controller 20 can be used to control the first refrigeration pipe 16 and the second refrigeration pipe 17 nested inside the carrier plate 2 to perform refrigeration operation, so that the first refrigeration pipe 16 and the second refrigeration pipe 17 cool the water sealed by the first sealing gasket 5 and the second sealing gasket 6 in the carrier plate 2. Since the first refrigeration pipe 16 is located outside the lower end of the outer mold sleeve 4 supported by the fixing plate 7, and the second refrigeration pipe 17 is located at the lower left and lower right sides of the outer mold sleeve 4, it is convenient to cool the outer mold sleeve 4, accelerate the molding of the heat transfer element processing material, and improve the processing efficiency.

[0029] like Figure 1 , Figure 3 and Figure 4 After the heat transfer element is formed, the controller 20 can be used to control the electric telescopic rod 8 to operate, so that the support plate 9 drives the inner mold sleeve 10 to rise, disconnecting the inner mold sleeve 10 from the outer mold sleeve 4, and then the controller 20 can be used to control the exhaust fans 18 symmetrically installed on the left and right sides of the support plate 9 to operate. Since a dustproof net 19 is arranged above the exhaust fan 18 and fits the support plate 9, and the lower end of the support plate 9 is hollow, it is convenient for the exhaust fan 18 to filter the outside air through the dustproof net 19 and extract it into the support plate 9, and then blow it onto the outer mold sleeve 4 and the inner mold sleeve 10, so as to dissipate heat from the mold and reduce heat loss.

[0030] like Figure 1 , Figure 2 and Figure 3 After the heat transfer element is formed and radiated, it can be taken out from the outer mold sleeve 4 for further processing. After the mold is used for a long time, the outer mold sleeve 4 can be taken out from the cover plate 3 for replacement. The screws fixing the inner mold sleeve 10 and the support plate 9 can be disconnected to replace the inner mold sleeve 10. The screws fixing the cover plate 3 and the carrier plate 2 can be disconnected to remove the first refrigeration pipe 16 and the second refrigeration pipe 17 from the carrier plate 2 for replacement. The dustproof net 19 and the support plate 9 can be disconnected to repair the exhaust fan 18, so as to prolong the service life of the mold.
