The invention relates to a manufacturing device for a
silica gel mold of a
surfboard fin, belonging to the technical field of
processing of surfboard fins. The manufacturing device comprises a base plate which is provided with a molding unit, a pouring unit and a
plasticine leveling unit, wherein four baffle plates are arranged in the molding unit and define into a rectangular shape; four slidersare arranged in the molding unit; a screw and two guide columns are arranged between each baffle plate and a slider located right ahead of the outer side of the same baffle plate; a press plate, a supporting frame, a press rod and four third guide columns are arranged in the
plasticine leveling unit; and feed drum supporting frames, a feed drum, a stirring blade and stirring blade fixing supportsare arranged in the pouring unit. The manufacturing device provided by the invention solves the problem of large occupied space for storage of a pouring frame of the
silica gel mold of the
surfboard fin, the problem of poor flatness of the
silica gel mold manufactured in the prior art, and the problem of difficult cleaning of residual bubbles in the silica gel mold and residual silica gel solidified on the wall of a silica gel filled container.
