[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] A mold for molding porous tube bundle fluororubber sealing plates, such as Figures 1-5 As shown, the molding die includes a lower die 1 and an upper die 2, and a fixing member 3 is fixedly connected to one side of both the lower die 1 and the upper die 2.

[0027] A middle mold 4 is fixed between the upper mold 2 and the lower mold 1, and the porous tube bundle fluororubber sealing plate is filled and molded on the middle mold 4.
