Description

Technical Field

[0001] The utility model relates to the technical field of vacuum mechanisms of vulcanizers, in particular to a vacuum mechanism of a rubber plate vulcanizer. Background Art

[0002] Rubber sheets are resistant to oil, acid and alkali, cold and heat, and aging. They can be directly cut into sealing gaskets of various shapes and are widely used in the pharmaceutical, electronic, chemical, antistatic, flame retardant, food and other industries. When processing rubber sheets, a rubber vulcanizing plate machine is required to provide the rubber sheet with the pressure and temperature required for vulcanization. To ensure the sealing effect, the vacuum mechanism of the existing rubber plate vulcanizer usually adopts an integrated structure and is directly installed under the fixed plate of the vulcanizer. The contact between the bottom and the moving plate is used to ensure isolation from the external air.

[0003] For example, the prior art publication number is CN218399055U, which is a vacuum mechanism of a rubber plate vulcanizer. The utility model realizes convenient fixation between the limit bar and the heating plate by setting a limit bar fixedly connected to the heating plate with bolts, and utilizes an elastic clamping ring fixedly connected to the end of the second hydraulic cylinder to realize convenient installation of the second hydraulic cylinder on the guide column. The sealing strip is slidably embedded on the inner side of the limit bar to realize the limitation of the vertical displacement of the sealing strip, thereby improving the application scope of the vacuum structure.

[0004] However, the above-mentioned prior art still has the following problems when in use: when the above-mentioned rubber plate vulcanizer is in use, the sealing strip is moved by the second hydraulic cylinder and the retaining ring. Since the contact area between the second hydraulic cylinder and the sealing strip is small, the sealing strip is prone to deformation after long-term movement, which will reduce the sealing between the sealing strip and the limit strip, and further affect the vacuum sealing between the moving plate and the frame plate. Based on this, the utility model provides a vacuum mechanism of a rubber plate vulcanizer with high sealing performance. Utility Model Content
