Abstract

The invention discloses an electric cable accessory silicon rubber heating vulcanization mold. The mold comprises an upper mold plate, a lower mold plate, a positioning frame and core rods, wherein aplurality of cavities are arranged between the upper mold plate and the lower mold plate; the core rods correspond to the cavities one by one and are positioned between the upper mold plate and the lower mold plate; an inner end of each core rod extends into each cavity; an outer end of each core rod is fixedly connected with the positioning frame; and a core rod heating device is arranged in eachcore rod. The electric cable accessory silicon rubber heating vulcanization mold has the advantages of short vulcanization time and high production efficiency.

Description

technical field [0001] The invention belongs to the field of cable accessory moulds, in particular to a silicone rubber heating vulcanization mold for cable accessories. Background technique [0002] At present, silicone rubber needs to be heated during the vulcanization process. Traditional mold heating, such as Chinese patent announcement number: CN101916631A, discloses a manufacturing mold for a composite insulator, which includes a lower mold, an upper mold, an electric heating plate, a heat shield and Water conveying board, the inside of the water conveying board is provided with a main rubber channel and a water channel, and the water jacket is installed under the water conveying board, and the water jacket has a middle-hole channel connected with the main rubber channel in the water conveying board and the water conveying board. The water inlet chamber and the water outlet chamber connected in series by the water channel, the water jacket passes through the heat insul...
