Embodiment Construction
[0057] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0058] figure 1 It is a flow chart of a method for manufacturing a sealing ring according to an exemplary embodiment, as shown in figure 1 As shown, the method includes:
[0059] In step 101, a mold is used to produce the sealing rubber strip, and at least two sealing rubber strips having a first preset length and a preset cross-sectional size are produced.
[0060] In step 102, according to the at least two sealant strips, at least two sealant strips whose length sum is equal to a second preset length are selected.
[0061] In step 103, the sealing strip is used to connect the mold, and the joints of at least two selected sealing strips are sequentially connected to form a sealing ring with a preset perimeter and a preset cross-sect...

The invention discloses a sealing ring manufacturing method and a mold, and belongs to the technical field of sealing rings. The method comprises the steps that at least two sealing rubber strips withthe first preset length and the preset section size are manufactured through a sealing rubber strip production mold, at least two sealing rubber strips with the total length equal to the second preset length are selected according to the at least two sealing rubber strips, through a sealing rubber strip connecting mold, joints of the at least two selected sealing rubber strips are sequentially connected to form a sealing ring with the preset perimeter and the preset section size, and the preset perimeter is equal to the second preset length. According to the embodiment of the invention, the sealing rubber strip production mold is used for producing the sealing rubber strips, and the sealing rubber strips are connected to form the required sealing ring, so that a sealing ring production mold with the size matched with that of the sealing ring does not need to be manufactured, the time for manufacturing the production mold is saved, and the manufacturing period of the sealing ring is shortened; and the manufacturing difficulty of the sealing ring is reduced, the requirement for production equipment is lowered, and then the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of sealing rings, in particular to a method for manufacturing a sealing ring and a mold. Background technique [0002] In the long-distance pipeline transportation industry, equipment such as ball receiving barrels, ball sending barrels, and filter separators are common. These devices are equipped with quick-opening blind plates, which are used on circular openings of pressure pipes or pressure vessels, and are mechanical devices that can realize quick opening or closing. The sealing ring is used to seal between the quick-opening blind plate and the circular opening of the pressure pipe or pressure vessel. Due to the large size of the quick-opening blind plate, a larger-sized sealing ring is required. [0003] In the related technology, the production of the sealing ring adopts an integrated molding method. First, the sealing ring production mold is made according to the size requirements of the sealing rin...
