Abstract
The utility model discloses a die for producing a silastic electric product with an umbrella skirt, which is mainly used for producing a silastic electric product with an umbrella skirt and without a longitudinal die assembling seam on the surface. The die solves the problem that an electric product produced by a common die can have a longitudinal die assembling seam, which leads the electric product to easily form a perfoliate conductive channel at the position of the longitudinal die assembling seam. The technical measures adopted by the die are as follows: the die for producing the silastic electric product with the umbrella skirt comprises an upper template, a lower template and a mandril. The die for producing the silastic electric product with the umbrella skirt is characterized in that a plurality of annular dynamic modules are overlapped between the upper template and the lower template; a cooperative structure inserted together is arranged between the end parts of two neighboring movable modules; cavities are formed in the dynamic modules which are overlapped together; and the mandril penetrate through the central positions of the cavities; and moreover, a rubber discharge port and a rubber feed port communicated with the cavities are respectively arranged at the position of the upper template and the position of the lower template.
