Description

Technical Field

[0001] The utility model relates to the technical field of full-cold-shrink cable terminals, in particular to a high-temperature vulcanization molding device for full-cold-shrink cable terminals. Background Art

[0002] The cold-shrink cable terminal head is made of elastomeric materials (commonly used are silicone rubber and ethylene propylene rubber) that are injection-vulcanized and molded in the factory, and then expanded and lined with plastic spiral supports to form components of various cable accessories. Prior art announcement number CN203427243U proposes a submarine cable factory joint vulcanization device, which includes a work platform and a vulcanization mold installed on the work platform. The vulcanization mold includes a vulcanization mold lower part and a vulcanization mold upper part. The vulcanization mold lower part is fixedly mounted on the work platform, and the vulcanization mold upper part is mounted on the vulcanization mold lower part. The two together form a mold cavity. The air outlet, air inlet and cooling water inlet are respectively arranged on the vulcanization mold upper part. The pressure gauge is arranged on the vulcanization mold upper part and is connected to the mold cavity of the vulcanization mold. The thermocouple is installed in the vulcanization mold and is connected to the control device through a signal line. However, some cold-shrink cable accessories with higher insulation performance requirements have thicker tube walls. In addition, the mold heating temperature during the heating and vulcanization process is not easy to be too high (too high temperature will destroy the physical properties of liquid silicone rubber). Under the condition of a certain injection speed, the thicker tube wall and the hot melt temperature that is not easy to be too high will result in a long vulcanization time, low production efficiency, and poor hot melt molding effect.
